Worldwide, lung cancer is the primary cause of cancer-related deaths. The majority of lung cancer cases are diagnosed at an advanced stage, which reduces the 5-year survival rate. At the moment, low-dose CT is the only screening option available for lung cancer, and it has certain drawbacks. According to a cancer genomics company, a blood test for early-stage lung cancer detection has been developed. Globally, lung cancer is the primary cause of cancer-related mortality. Lung cancer was the cause of approximately 2 million diagnoses and 1 in 8 deaths in 2020. The type of cancer, the time of diagnosis, and whether the cancer has spread to other parts of the body all affect a person’s 5-year survival rate for lung cancer. Early-stage lung cancer is more curable. Previous studies have demonstrated that because many people do not exhibit clear symptoms at an early stage, the majority of lung cancer cases are diagnosed at an advanced stage. Currently, low-dose computed tomography (CT) scanning is the only method of screening for lung cancer. CT scans, however, occasionally result in false positives or negatives.

Currently, research is being done on a novel method of early lung cancer detection. The first results of a novel blood test for the identification of early-stage lung cancer were presented at the annual congress of the European Society for Medical Oncology this year. created by Personalis Inc., a cancer genomics company. The new test, known as the NeXT Personal ctDNA assay, can identify minute amounts of circulating tumor DNA (ctDNA) in blood, indicating the presence of residual or recurrent cancer, according to Dr. Richard Chen, executive vice president of research and development at Personalis Inc. and chief medical officer. According to Chen, who spoke with Medical News Today, “the NeXT Personal technology leverages whole genome sequencing and advanced noise suppression with NeXT SENSE technology to identify an ultra-sensitive, unique genetic signature derived from a patient’s tumor.”. “This distinct signature is monitored in the patient’s bloodstream over an extended period to detect any lingering or recurrent cancer, attaining an industry-best sensitivity of approximately 1 part per million of ctDNA. He continued, “This increased sensitivity offers the potential for earlier detection, more accurate monitoring, earlier recurrence risk assessment and intervention, and significant advancement in lung cancer care.

The primary finding from the work with the NeXT Personal assay in TRACERx, according to Dr. Charles Swanton, principal investigator for the study and deputy clinical director of the Francis Crick Institute in London, concerns disease stratification in early-stage lung cancer. “At the moment, we don’t always have the ability to direct additional supplemental therapy, called adjuvant therapy, to those who would benefit it most because we have an imperfect system to understand which patients will typically have a poor clinical outcome following surgical resection of their primary tumor with curative intent,” Swanton told Medical News Today. This results in some patients receiving insufficient care while others receive excessive care. Better methods of classifying patients into those who will and won’t recover well from surgery are therefore desperately needed. Our investigation was set against this realization. According to Swanton, it’s critical to accurately categorize patients as high- or low-risk because this allows for “individualized” adjuvant therapy trials.

“It could have a significant impact to be able to withhold treatment from patients who are unlikely to benefit while providing it to a population of patients who would.” he said. In terms of recurrence detection, we are aware that recurrence can be identified nearly a year ahead of routine clinical surveillance in patients who have evidence of ctDNA in the blood after surgery. Similar to the pre-operative data, this allows for the implementation of aggressive treatment in the early-metastatic setting, thereby providing a more individualized approach to treatment. According to Chen, Personalis is now offering the NeXT Personal test for clinical testing as a part of an early access program. According to him, between 20 and 40 percent of patients with early-stage lung cancer eventually experience a recurrence, depending on the stage. The sensitivity of some recurrence detection techniques, such as imaging or other blood tests, may be restricted. It may be possible to treat or advance treatment for lung cancer patients sooner if more sensitive methods for identifying cancer that remains after treatment or recurs. “.

According to Swanton, the new blood test’s next research steps would involve validating the results in prospective cohorts. He stated, “This will pave the way for routine clinical use and the identification of particular cohorts where an ultra-sensitive assay can be applied.”. Dr. John Roberts, a thoracic surgeon with Lynn Cancer Institute, a division of Baptist Health South Florida, at Boca Raton Regional Hospital, told Medical News Today after reviewing details about the new NeXT Personal ctDNA assay that since CT scanning has been shown to reduce lung cancer mortality more than any medical intervention, an accurate blood test should have a similar effect. He clarified, “All of our blood testing for lung cancer only detects advanced cancer.”. Since a CT scan is currently the only method available for screening for lung cancer, any test that could be used as an early cancer screening would represent a significant advancement. According to Roberts, the majority of lung cancer patients who experience recurrence following treatment are already incurable when the disease is detected. It would be beneficial for any test to identify recurrences early on. “.

Sara Belton, PhD, a nurse navigator for the Lung Screening Program at the Cardiothoracic Outpatient Clinic in California at Providence Saint John’s Health Center, was also interviewed by Medical News Today regarding this study. She stated that any tools that can assist clinicians in the diagnosis and long-term management of lung cancer are most welcome. She works as a nurse navigator and focuses on lung cancer screening. According to Belton, “a blood test for lung cancer genome detection is being developed by several research consortia and is considered by many in the field as the ‘Holy Grail’ for lung cancer diagnosis.”. “If this research is successful, physicians will benefit from having a more accessible and potentially more accurate modality for screening for lung cancer than the current gold standard, CT imaging scans, which are best used in conjunction with clinical interpretation and excellent imaging visualization. I’m glad to hear this and am interested in learning more about their outcomes in the future. She went on to say that having an inexpensive, readily available blood test that can be used to screen for lung cancer will enable medical professionals to increase screening efforts, which are currently low in the US.

According to Belton, “current clinical guidelines for lung cancer screening recommend that only current or former smokers who are over 50 and have a smoking history of at least 20 pack years be screened for lung cancer every year.”. Nonetheless, these recommendations do not apply to the up to 10% of lung cancer patients who have never smoked. These are frequently the ones whose lung cancer is discovered too late to receive the best care and results. “A more widely available blood test would enable us as clinicians to identify these non-smokers who are at risk, and would enable us to intervene and treat them at an early enough stage to ensure favorable health outcomes, and potentially prevent them from passing away from lung cancer,” the speaker continued. “This would be a huge advancement in lung cancer care and screening, and I am optimistic that a blood test of this kind will be made commercially available in the coming years”.

All highly processed foods associated with diabetes and cancer

All highly processed foods associated with diabetes and cancer

Comments 0 Comment

A recent study found that the emergence of several chronic conditions is linked to a diet high in ultra-processed foods. Extremely processed foods derived from animals and drinks with added sugar and artificial sweeteners are especially prone to cause diabetes, heart disease, and cancer at the same time. Experts advise against overindulging in ultra-processed foods like breads, cereals, and plant-based substitutes, even though this study did not find any such connection. Ultra-processed foods can be difficult to identify because they are usually grouped based more on processing level than nutritional value. Ultraprocessed food consumption has been connected to a number of distinct chronic illnesses, including diabetes, cardiovascular disease, and cancer. They are also connected to comorbidities, or combinations of these diseases, a large study now confirms. The study indicates that individuals with a diet high in ultra-processed foods have a 9 percent higher chance of developing cardiovascular and cardiometabolic comorbidities. The study found that beverages sweetened with artificial sweeteners and animal products had the highest increase in risk. The researchers did not discover any correlation between comorbidities, plant-based substitutes, and ultra-processed breads and cereals.

Data from the European Prospective Investigation into Cancer and Nutrition (EPIC) are analyzed in this study. A prospective cohort study is being conducted to investigate the relationships between environmental, genetic, dietary, and lifestyle risk factors and cancer as well as other diseases. The researchers examined data from 266,666 participants for the new study. The NOVA index was used to rank the foods they consumed in relation to their processing level. A median of 11.2 years of follow-up was conducted to monitor the emergence of chronic illnesses. The precise characteristics that characterize a problematically processed food are a matter of debate. This is mostly due to the fact that most modern foods require some processing, unless they are purchased straight from the farm. Healthy foods like tofu, simple bread, canned tuna or beans, and cheese can all be considered processed foods. Ultra-processed foods, or UPFs, are the main cause for concern, though. Most researchers use the NOVA index, which was created by Carlos Monteiro and associates at Sao Paolo University in Brazil, as the standard. The World Health Organization’s scientist in nutrition and metabolism and lead investigator for the new study, Dr. Heinz Freisling, described how the index operates as follows: NOVA classifies foods into four categories: fresh or minimally processed, culinary ingredients, processed, and ultra-processed, not according to their nutrient profile.

The final category, according to study observer Michelle Routhenstein, a preventive cardiology dietitian at EntirelyNourished . com, is foods that are made solely with a combination of industrial processes. There is still opportunity for individual opinions because ingredients play a significant role in the overall story and processing level alone does not tell it all. According to Dr. Dot Freisling, foods classified as [u]ltra-processed are those that are unfit for home preparation due to a shortage of ingredients and equipment. Colorants, artificial sweeteners, food preservatives, and other substances are a few examples of these ingredients. It is not yet clear why ultra-processed foods show this strong link with a wide range of conditions, which makes it a hot topic of research why consuming them might lead to comorbidities, according to Dr. Freisling. He surmised that it might be related to the easily accessible and reasonably priced nature of these foods for the end user. People often overindulge in these because they are meant to be flavorful and shelf-stable. For instance, according to Dr. Freisling, a bag of tortilla chips can easily defeat a simple boiled corn cob. He added that artificial sweeteners and other additives might be involved. He went on to say that the modified food matrix, which is a food’s natural structure or matrix at the microscopic level, and the complete absence of dietary fiber might both be significant factors. Routhenstein pointed out that the process. She also mentioned that ultra-processed foods like chips, crackers, and cookies have the highest AGE levels per gram.

The survival and relapse rates of cervical cancer are improved with induction chemotherapy.

The survival and relapse rates of cervical cancer are improved with induction chemotherapy.

Comments 0 Comment

Advances in screening, prevention, and therapy have contributed to recent increases in cancer survival rates. Human papillomavirus (HPV) vaccination as a preventative measure and screening for early diagnosis have been the main focuses of efforts to increase cervical cancer survival. Nonetheless, some people continue to be diagnosed with advanced cancer that has to be treated. According to a recent study, induction therapy may increase the overall survival rates of advanced cervical cancer by 39%.

At sites in the United Kingdom, Mexico, India, Italy, and Brazil, researchers gathered a cohort of 500 women with cervical cancer that measured more than 4 centimeters (cm) across (stage 1B2 to stage 4A) or less than 4 cm (stage 1B1 if the cancer is also in the lymph nodes). This group was divided into two arms; the first underwent six weekly doses of chemotherapy consisting of carboplatin and paclitaxel, followed by up to six weeks of treatment with radiation therapy and the chemotherapy medication cisplatin for their cancer. For their malignancy, the second trial arm’s participants had only the conventional six weeks of chemotherapy and radiation treatment.

After five years of cohort follow-up, researchers discovered that patients who had undergone induction chemotherapy had a noticeably higher overall survival rate. Patients who got induction therapy, chemotherapy, and radiation therapy had an overall five-year survival rate of 80%, while patients who had only standard chemotherapy and radiation therapy had a five-year survival rate of 72%. For patients who got the induction therapy initially, this meant a 39% lower chance of death over a five-year period. People who live with cancer without it progressing or spreading are said to be progression-free survivors.

At five years, the progression-free survival rate for patients who had received induction therapy, chemotherapy, and radiation was 73%, while the rate for patients who had just received standard chemotherapy and radiation was 64%. This indicated a 35% decrease in the likelihood of progression during the five years that followed treatment. The group receiving induction chemotherapy experienced more adverse effects than the other; 59% of that group’s side effects interfered with their ability to go about their daily lives, compared to 48% of the other group.

According to a 2023 study by the American Cancer Society (ACS), the United States’ cancer death rate has dropped by a third since 1991. The American Cancer Society (ACS) attributes the decline in U.S. mortality to advancements in early identification and treatment. Other nations have also witnessed a decline in mortality; early in 2023, the National Health System in the United Kingdom reported a 10% rise in cancer survival rates since 2005. The advent of induction chemotherapies is one advancement in treatment. Induction therapy is described as “the first treatment given for a disease” by the National Cancer Institute, following previous medical interventions.

Chemotherapy administered before to other treatments for patients with aggressive malignancies that have a high chance of spreading is known as induction chemotherapy. They have previously been demonstrated to be successful in raising overall survival rates for a number of cancers, including pancreatic, lung, acute myeloid leukemia, and breast cancer. After these therapies, further radiotherapy, surgery, or chemotherapy may be administered. Additionally, Dr. McCormack stressed that cervical cancer is a disease that is largely preventable. In order to help prevent infection and the subsequent development of cervical cancer, the HPV vaccine was first made available to adolescent girls in 2006 and subsequently to boys prior to their sexual maturation.

Between 2012 and 2019, the United States had a 65% decline in the rate of cervical cancer in people in their 20s. Researchers hypothesize that this decline “foreshadows” a subsequent decline in cervical cancer rates in that region and is caused by the introduction of the HPV vaccine in 2006.

Globally, non-melanoma skin cancer now has a higher mortality rate than melanoma.

Globally, non-melanoma skin cancer now has a higher mortality rate than melanoma.

Comments 0 Comment

Worldwide, non-melanoma skin malignancies caused more fatalities than melanoma because they are far more prevalent. Skin cancer rates may be rising in part due to the aging population. Skin cancer that is non-melanoma is curable and, in most circumstances, preventative.

According to a study being presented at the European Academy of Dermatology and Neurology Congress 2023, non-melanoma skin malignancies now account for more deaths globally than melanoma alone. The prevalence of non-melanoma skin cancers is so great that even though they are less lethal than melanomas, the number of fatalities from them is larger, according to the study’s authors. In contrast to the 324,635 occurrences of melanoma, there were approximately 1.2 million cases of non-melanoma skin cancer in 2020. According to the study, non-melanoma skin cancers caused 63,700 deaths globally and 78% of all skin cancer cases in 2020. At the same time, 57,000 people died from melanoma.

What to know about skin cancers other than melanoma

Skin cancers other than melanoma grow slowly in the top layers of the skin. Squamous cell carcinoma and basal cell carcinoma are common varieties. These malignancies are easier to cure and have a lower propensity to spread to other parts of the body. In spite of relatively low death rates, the study’s authors noted that fair-skinned and older people in the United States, Germany, the United Kingdom, France, Australia, and Italy experience a high incidence rate of skin cancer. The researchers point out that skin cancer risk exists even in nations with a significant population of people with dark complexion.

“This study offers a fascinating look into the incidence and fatality rates of skin cancer around the world. According to Dr. Michele Green, a cosmetic dermatologist at Northwell Lenox Hill Hospital in New York City who was not involved in the study, “It is interesting that the availability of dermatologists in a given area did not correlate with melanoma incidence or mortality rates, suggesting that other factors besides dermatologist density successfully decrease mortality-to-incidence ratios. “It is also surprising to see how high the mortality rate for non-melanoma skin cancers is, as most would assume melanoma to be the most lethal skin cancer type,” she said in an interview with Medical News Today.

The increase in cases of non-melanoma skin cancer

Dr. Brian Toy, a dermatologist and clinical professor in the School of Medicine at the University of Southern California who was not involved in the study, said that historically, melanoma has a much higher risk of death than non-melanoma skin cancers like basal cell carcinoma and squamous cell carcinoma, which are typically not life-threatening. Despite important developments in treating metastatic melanoma with immunotherapy, which has essentially supplanted conventional chemotherapy, Toy stated to Medical News Today that this is still the case. Immunotherapy has significantly improved patients’ chances of surviving, especially those with metastatic melanoma.

“In this study, the absolute number of patient deaths attributed to non-melanoma skin cancer did exceed those with melanoma, but that is only because the sheer number of non-melanoma skin cancers (1,198,073) far exceeded the number of melanomas (324,635),” he continued. “An analogy would be to compare the number of fatalities from motor vehicles to those from motorcycles. Despite the fact that driving a car is statistically safer than riding a motorbike, there are more car accidents every year because so many more people drive than ride bikes. People ought to visit a dermatologist frequently. The doctor checks for non-melanoma skin cancers during routine checkups and advises early treatment to stop them from progressing to a life-threatening stage.

Non-melanoma skin cancer incidence and mortality rates are rising, according to Green, for a number of reasons. One of them is the aging of the world’s population. As we become older, our cumulative exposure to UV radiation raises our risk of getting skin cancer. Another reason is the thinning of our ozone layer. By absorbing UV rays, the ozone layer shields our atmosphere from harm.

Unless it has personally touched them, a friend, or a family member, “patients in the United States are generally unaware of the signs and symptoms of skin cancer,” Toy added. “Countries with a skin cancer epidemic, like Australia and New Zealand, where the incidence is extremely high due to the sheer number of fair-skinned people living in a sunny climate, have much more awareness.” The authors propose that stepping up public education campaigns about risk factors can be beneficial. In order to manage the condition, programs should include dermatologists, general practitioners, and other medical professionals.

The report offers incidence and death statistics for every country, including those where they are significantly higher than in the United States. Dr. Trevan Fischer, a surgical oncologist and assistant professor of surgical oncology for Saint’s John’s Cancer Institute at Providence Saint John’s Health Center in California who was not involved in the study, notes that it also lumps several types of non-melanoma skin cancers together. “Kaposi sarcoma and Merkel cell carcinoma are two additional, extremely uncommon, but potentially aggressive forms of skin cancer. The death rates increased as a result of their being included with non-melanoma malignancies. According to Fischer, Medical News Today, basal cell and squamous cell carcinomas have substantially lower mortality rates.

He continued, “The other question regarding death rates is, did the patients die from the skin cancer or another health condition, but they had skin cancer?” For instance, if someone has a kidney transplant and later dies from a heart attack, did they pass away from kidney disease or did they pass away from a heart attack while they were suffering from kidney illness? These are two distinct objects.

Treatment for non-melanoma skin cancer

The kind, size, and location of skin cancer all affect how it is treated. Except in cases when the tumor is deep or has migrated to other parts of the body, dermatologists are able to treat the majority of cases of non-melanoma skin cancer. After that, an oncologist is frequently contacted. Excision and Mohs surgery are two surgical alternatives for treating the condition, according to Green. “A biopsy is taken during excision surgery and sent to a lab to make sure there is no trace of cancer still present. During Mohs surgery, the lesion is removed one layer at a time. A pathologist examines each layer as it is removed to check for abnormal cells, and the process is continued until there are no aberrant cells left in the tissue.

Cryosurgery or curettage and electrodesiccation may be suggested by your doctor if surgery is not an option, she continued. “Curettage and electrodesiccation involves scraping the lesion’s surface with a curette before burning the residual lesion with a hyfrecator. In order to treat superficial lesions, cryosurgery uses liquid nitrogen; it can be used alone or after curettage and electrodesiccation. A topical treatment called fluorouracil, which prevents the abnormal cells from dividing, can also be used to treat some basal cell carcinomas, according to Green.

Breast cancer: Can a wearable device help to detect it?

Breast cancer: Can a wearable device help to detect it?

Comments 0 Comment

To screen for breast cancer at home, researchers created a wearable gadget.

Initial testing reveal that it is capable of detecting tiny cysts that are comparable in size to early-stage breast tumours. To confirm the effectiveness of the gadget, clinical trials are required.

One day, a cutting-edge piece of wearable technology that can be fastened to a bra might enable individuals to identify breast cancer symptoms while lounging at home.

With approximately 1 in 6 cancer-related deaths among women, breast cancer is the most common cancer in the world. Women make up the great majority of breast cancer patients. Men experience 0.5% to 1% of cases, though.

If discovered when the cancer has not yet moved outside of the breast, breast cancer has a 5-year relative survival rate of up to 99%. The 5-year survival rate drops to 30% if discovered later, such as when cancer has spread to distant bodily areas like the lungs, liver, or bones.

Currently, the most popular approach for detecting breast cancer is a mammography, an X-ray imaging procedure.

Mammograms must be performed in an imaging center even though they are typically efficient at detecting 87% of malignancies. This limits access for many people, especially those with low incomes, who could postpone screening as a result of the high associated expenses and challenges in organizing transportation.

The health outcomes for those diagnosed with the condition globally could be improved by initiatives to increase accessibility and lower the cost of breast cancer screening.

Researchers recently created a wearable ultrasound breast patch that could enable patients to scan for breast cancer at home.

Bard-certified doctor Dr. Kamila Seilhan, stated: “This wearable ultrasound device may help patients at high risk of breast cancer in the interim between routine mammograms by enabling early tumor detection.”

A breast-attached wearable breast cancer detector

The same ultrasound technology that imaging centres utilise is the foundation of the device. However, because of the piezoelectric materials used, it can be made smaller to function as a portable ultrasound scanner. Through a mechanism called piezoelectricity, crystals transform mechanical energy into electrical energy, which in this instance can be used to interpret ultrasound measurements.

“The device sends sound waves into the breast tissue, and as it moves across the breast, it produces high-quality images identifying cysts that may need to be investigated by a breast cancer specialist,” said Dr. Jennifer Tseng, F.A.C.S., medical director of breast surgery and a double board-certified surgical oncologist specializing in breast cancer at City of Hope Orange County Lennar Foundation Cancer Centre in Irvine, California, who was not involved in the research.

To make the device wearable, the researchers created a flexible, 3D-printed patch with honeycomb-like holes. The patch fastens to a bra with holes so it may touch the skin and scan breast tissue there.

The entire breast may be imaged thanks to the scanner’s six various positioning options. In order to capture photographs from various perspectives, it can also be rotated.

The scanner has already been tested on a 71-year-old woman who has a history of breast cysts. They were able to identify cysts with the gadget that were as small as early-stage tumours, or 0.3 centimetres in diameter. According to their findings, the images produced had an 80mm depth and a resolution comparable to that of conventional ultrasounds.

Senior author of the study Canan Dagdeviren, Ph.D., Associate Professor of Media Arts and Science at Massachusetts Institute of Technology (MIT), stated that the technology makes it simple to repeatedly take pictures from the same location.

Increased screening availability for breast cancer

Dr. Dagdeviren stated that the ultimate purpose of the device is to reach underrepresented women, including those living in less economically developed nations, and to make breast cancer screening more accessible and affordable.

Dr. Seilhan remarked that if successful, the device could be especially helpful in isolated locations without simple access to medical facilities.

“Healthcare facilities and organizations with limited funds can purchase the device more easily because of its low cost,” she said.

She continued by saying that while the gadget is simple to operate, it might be useful in settings where medical personnel have limited technical expertise.

Dr. Tseng pointed out, however, that in order for patients in less developed nations to benefit fully from diagnostic technologies, it is equally critical for them to have better access to those tools.

However, she added, “patients still need to have the data reviewed by an expert who can recommend what to do next.” This device may assist patients identify potential problem areas that they were unable to identify before.

When will the breast cancer wearable device be obtainable?

According to Dr. Dagdeviren, the device might be usable for 4-5 years. She is starting a business to achieve this goal and is looking for partners and investors. For mass production and FDA certification, she stated, “we will need about $40 million.”

In spite of the fact that the device now needs a “bulky computer interface” to process photographs, the author continued, her team is currently working on a more portable design and will soon release an iPhone-size image processor.

The researchers are also creating a workflow that will enable artificial intelligence to examine data and produce diagnostic evaluations that might be more precise than those made by a radiologist comparing photos that were obtained over some time.

Experts spoke with Dr. Richard Reitherman, Ph.D., a board-certified radiologist and medical director of breast imaging at MemorialCare Breast Centre at Orange Coast Medical Centre in Fountain Valley, California, who was not involved in the study to learn more about potential future uses for the device.

“This kind of product will be a welcomed supplemental addition to women’s health care,” the doctor said. “If it can be demonstrated to be on par with mammography and dedicated breast ultrasound for breast cancer screening, it will be a welcome alternative.”

However, he pointed out that one of the biggest obstacles for any new gadget is completing successful clinical trials, which will probably require collaboration with the American College of Radiology.

“This is a complex and difficult proposition,” he said. “The jump from translational science to clinical efficacy remains to be seen.”

What are the limitations of the study?

Its limits stem from the fact that the technology is still in its early stages of development.

The University of Kansas Cancer Centre breast radiologist Dr. Onalisa Winblad, who was not part of the study, stated that she does not currently support its use because it “does not have scientific data to prove utility.”

The linked article’s photographs are of low quality when compared to those from our normal breast ultrasound. In patients with dense breast tissue, ultrasonography is a tool that is beneficial in addition to mammography.

Dr. Tseng concurred that although ultrasonography is a useful tool for breast cancer screening, it cannot take the place of mammography and other types of preventive treatment provided by a breast cancer specialist.

Different technologies are more effective than others at detecting various breast alterations. For instance, while some calcifications cannot be seen with ultrasonography, others can be seen with mammography, she noted.

She stated that two of the most crucial elements in how effectively the tool performs as a breast cancer screening tool are “the device’s ability to find true positive cases and avoid fake positive cases.“

She continued by saying that even while the tool might be simple to use, how well it works may still rely on the user. Also, she added that because the human breast varies from person to person and even among individuals, large-area and deep-tissue imaging can be challenging.

When challenged about the device’s limits, Dr. Reitherman stated that in order to maintain good quality metrics, the scanner must be operated under medical supervision, such as through “virtual supervision by a radiologist.”

“Therefore, the existing medical community and physicians that would be interpreting and recommending actions based on this device’s information would need to be on board,” he said.

Cancer: physical activity a day could lower your risk.

Cancer: physical activity a day could lower your risk.

Comments 0 Comment

In a recent study, the impact of vigorous intermittent lifestyle physical activity (VILPA) on the risk of developing cancer was examined.

Using information from wrist-worn accelerometers, researchers followed 22,398 non-exercisers’ health records for cancer for nearly 7 years while also tracking their daily intense activity.

When compared to not participating in VIPLA, 4.5 minutes of VILPA per day, divided into 1-minute bursts, was linked to a 32% lower chance of developing cancer.

Power walking, lugging groceries, and climbing stairs are just a few examples of the many possibilities that exist in daily life for strenuous physical activity.

The importance of physical activity to overall health and wellbeing cannot be overstated. According to research, regular exercise can reduce the risk of developing chronic diseases like cancer, diabetes, and cardiovascular disease.

In fact, the World Health Organisation (WHO) reports that those who are not adequately active have a death risk that is 20–30% higher than those who are.

Even though the benefits of physical activity are obvious, only about 1 in 3 women and 1 in 4 men globally adhere to the guidelines for 75 minutes of strenuous exercise or at least 150 minutes of moderate exercise per week.

Good news has arrived from a recent study for those who dislike or are unable to engage in structured, intense exercise.

Just 4.5 minutes per day of vigorous-intensity physical exercise undertaken in 1-minute bursts was related with an up to 32% decreased risk of cancer, according to wrist-worn accelerometer data taken from 22,398 non-exercising people collected from the UK Biobank.

VILPA: What is it?

Short bursts of physical activity that are a regular component of our lifestyle (daily living) are referred to as vigorous intermittent lifestyle physical activity (VILPA) by Dr. Stamatakis and his colleagues.

VILPA examples include, but are not restricted to:

  • climbing hills
  • ascending stairs
  • power walking, also known as maximising walking pace for a short distance (like 100–200 metres) to reach intense intensity, involves carrying children or groceries for 50–100 metres.
  • intense housework.
  • VILPA differs from conventional intense physical activity in that it is intermittent and transient, lasting up to two minutes at a time, as opposed to continuous and planned.

Effects of VILPA and cancer risk

The study was a prospective cohort study of adults, aged 40 to 69, who provided the UK Biobank with their data.

The research team led by Dr. Stamatakis only included participants from the accelerometer-wearing group who reported not exercising in their free time and taking one or fewer leisurely walks per week in their analysis of the association between VILPA and cancer incidence.

The study removed participants who provided incomplete information, had a history of cancer, or improperly wore the activity monitor.

22,398 participants made up the study population, and their average age was 62. 54.8% of these were female, and 96% of them were white.

The researchers found 2,356 new cancer occurrences throughout a mean follow-up period of 6.7 years, including cancer registration, hospitalisation for cancer, or death from any malignancy.

The researchers utilised a machine-learning method known as “random forest” to categorise accelerometer-recorded physical activity based on intensity — vigorous, moderate, and light.

VILPA reduces cancer risk by just a few minutes every day.

The majority of VILPA incidents took place in spurts of up to one or two minutes. People participated in VILPA for a maximum of 16 minutes, or about 4.5 minutes per day on average.

According to statistical assessments, the association between VILPA and cancer risk is almost linear, meaning that a person’s risk of developing cancer decreases as they engage in more VILPA.

People who engaged in VILPA for an average of 4.5 minutes per day, in short bursts of up to 1 or 2 minutes, had a 20% lower chance of developing cancer than those who did not engage in any VILPA (6.2% of study participants).

Previous studies have demonstrated a link between insufficient physical activity and several cancer forms. These consist of:

  • liver
  • lung
  • kidney
  • gastric cardia (a type of stomach cancer)
  • endometrial
  • Leukaemia myeloid
  • myeloma
  • colorectal
  • neck and head
  • bladder
  • mammary cancer
  • esophageal adenocarcinoma (esophageal cancer)

This study demonstrates that those who engaged in 4.5 minutes of VILPA daily have a 31% lower risk of developing certain physical activity-related malignancies.

The least amount of VILPA necessary to significantly lower the chance of developing cancer was also determined by the researchers. They discovered that 3.4 minutes of VILPA per day can reduce the risk of cancer overall by 17% and 3.6 minutes of VILPA per day can reduce the risk of cancer linked to physical activity by 18%.

More study is required to determine how VILPA affects cancer.

A relatively small quantity of strenuous lifestyle activity can have such a large link with decreased cancer risk, according to the “high-quality study,” according to Dr. David Raichlen, professor of biological sciences and anthropology at the University of Southern California.

According to him, “the authors used a novel machine learning-based method to identify behaviours and this study moves the field forward, allowing us to better understand the benefits of this form of physical activity on [the] risk of developing cancer.”

Because of the study’s methodology, Dr. Raichlen advised that causality could not be established; however, “this work certainly suggests that future intervention studies using VILPA are warranted.”

According to Prof. Markus Gruber, chair of Training and Movement Science and director of the University Konstanz’s Human Performance Research Centre, the study supports the long-held belief in exercise science that “intensity matters.”

Prof. Gruber made the same observation as Dr. Raichlen, namely that although the study’s data, methods, and analysis are sound, the study is cross-sectional and can only report relationships between VILPA and cancer incidence.

When challenged about the connection between VILPA and cancer incidence, Prof. Gruber responded that there are a number of plausible “explanations for the results that need to be tested.”

He claims that VILPA may either directly lower the risk of cancer, boost physical fitness, or show superior physical fitness, which is linked to a lower risk of cancer. Additionally, VILPA may reduce the effects of aging-related fitness decreases and reduce cancer risk by doing so.

Overall, according to Prof. Gruber, VILPA is a promising substitute for duration-based advice on physical activity, “especially for people who don’t like to exercise.”

Melanoma: Black man at 26% higher risk to die.

Melanoma: Black man at 26% higher risk to die.

Comments 0 Comment

Significant melanoma discrepancies between racial and ethnic groupings have been discovered by researchers.

Using the National Cancer Database, researchers discovered that Black males had the lowest survival rates for melanoma diagnoses and a 26% higher mortality risk than white men.

Put on sun-protective clothing, use sunscreen, and examine your skin once a month to protect yourself from melanoma.

While there are many studies on both male and female melanoma instances, there is little information on how race affects this skin disease, particularly in men.

A group of experts looked over the National Cancer Database to find out more. They looked at male non-Hispanic white, non-Hispanic black, non-Hispanic Asian, non-Hispanic American Indian/Alaska Native instances of primary cutaneous invasive melanoma.

Their data showed melanoma incidence differences between racial and ethnic groupings.

The trunk was the most typical site for melanoma in both white people and American Indian/Alaskan Native people. Men of color Black, Asian, and Hispanic had their lower extremities found to have melanoma, though.

The majority of stage 3 or stage 4 melanomas (48.6%) were seen in Black people. White guys (75.1%) and Black males (51.7%) had the highest 5-year overall melanoma survival rates.

According to research, black people with melanoma had a 26% higher mortality rate than white people with the same diagnosis.

Dr. Bianka Bubic, study author and a dermatology research fellow at The Ohio State University Wexner Medical Centre, said, “We hope that this study lays the foundation for future research to explore the reasons for why there are different presentations and survival among men of diverse racial groups in melanoma.”

Survival rates for melanoma vary by race

Researchers are currently looking into why Black people have a higher chance of developing severe melanoma. Pigmented lesions that may have variations in size, form, symmetry, or pattern can be early indicators of melanoma.

A board-certified dermatologist at Psoriasis Telehealth in Palo Alto, California, Dr. Faranak Kamangar, told that early detection of skin abnormalities in the Black community may be more challenging, thus postponing diagnosis.

She pointed out that the results emphasise the value of early cancer screening in many racial and ethnic groups.

Dr. Kamanger pointed out that socioeconomic issues such a lack of cheap insurance and medical treatment may disproportionately affect the severity of melanoma in Black communities, which could result in a diagnosis at a late stage.

“The main tendency, that Black men are diagnosed with melanoma at later stages, making it less likely to be treated and probably leading to greater rates of morbidity and mortality for this population, has been known to us for some time. The research also confirms previously reported findings that Black men are more likely to develop acral lentiginous melanoma, a subtype of melanoma that is typically detected at a later stage and may occur in difficult-to-examine body regions. Bob Marley is a well-known illustration. He unfortunately had a late diagnosis of melanoma and passed away from it,” according to board-certified dermatologist Dr. Faranak Kamangar.

Acral lentiginous melanoma is the most prevalent melanoma subtype in Black people, but it is also more challenging to identify and diagnose early.

Dr. Wael Harb, a haematologist and medical oncologist at MemorialCare Cancer Institute at Orange Coast Medical Centre in Fountain Valley, California, said that acral lentiginous melanoma “typically appears on less noticeable or examined areas like the palms, soles, or under the nails.”

Are there genetic factors that influence melanoma risk?

Racial and ethnic inequalities in melanoma risk may also be influenced by genetics.

According to Dr. Kamanger, “Acral lentiginous melanoma has higher rates in this population due to genetic predispositions and, in general, is diagnosed at a later stage.”

We have now discovered genes that predispose to acral lentiginous melanoma, and this is the key factor contributing to greater risk among some groups. Diagnosis may be delayed if the nails and bottom of the feet are involved. Except for the amelanotic subtype, melanoma is often pigmented and brown in colour, according to Dr. Kamanger.

Dr. Harb emphasised that acral lentiginous melanoma frequently manifests in locations that are not as exposed to the sun. This may explain why certain body parts, such as the palms, soles, and areas under the nails, are particularly vulnerable.

Dr. Harb noted that “this type of melanoma frequently develops in areas with less melanin, which provides natural protection against UV damage.”

Dr. Harb contrasted this with the development of superficial spreading melanoma, which frequently appears as a new or changing mole or discoloured area on sun-exposed skin.

The different ways that melanoma manifests in Black and White people emphasizes the significance of thorough skin inspections that include all body parts, not just those that are regularly exposed to the sun.

Research on the prevalence of melanoma in various racial groups is still lacking.

The majority of research papers conducted so far focus on white people’s melanoma cases. Dr. Kamanger noted that as a result, the conclusions that may be drawn are limited by the tiny sample size of Black men.

The primary flaw with this study is that Black men make up less than 0.5% of the population. To obtain useful sub-data, this is a very small quantity, as Dr. Kamanger pointed out.

“The study has some limitations, even if it offers insightful information. It does not take into consideration disease-specific survival, which limits our capacity to distinguish between melanoma mortality and death from other causes,” according to Dr. Harb.

Additionally, certain data were missing, which may have impacted the precision and thoroughness of the findings.

Additionally, compared to white people, there were significantly fewer instances of melanoma among ethnic minority groups. Dr. Harb continued that this can result in bias because the sample might not accurately reflect the entire population.

Taking steps to prevent melanoma

The first step in preventing skin cancer is to shield yourself from the sun. There is no safe level of ultraviolet light exposure, according to Dr. Kamanger, who described ultraviolet light as a real carcinogen.

“UPF clothing, SPF 30 and above sun protection, and seeking shade should be practised.”

Every part of your body, including your feet and nails, should be examined once a month, according to Dr. Kamanger.

When in doubt, schedule a yearly skin cancer test with a board-certified dermatologist, said Dr. Kamanger.

According to Dr. Bubic, “any lesions that may be changing, increasing in size, bleeding, or not healing appropriately should be evaluated.”

Improve melanoma treatment with fecal transplant?

Improve melanoma treatment with fecal transplant?

Comments 0 Comment

Using immune checkpoint inhibitors like pembrolizumab or nivolumab in conjunction with fecal transplants demonstrated the procedure’s safety in patients with advanced melanoma, according to a phase 1 clinical trial.

65% of the trial participants experienced a favorable response to immunotherapy. Following the fecal transplant, positive responders’ gut microbiomes revealed a rise in helpful bacteria and a decrease in dangerous bacteria.

Larger phase 2 trials will be carried out, and the use of faecal transplants in difficult-to-treat malignancies like pancreatic cancer will be investigated.

Numerous cancer patients have recently benefited from a type of treatment called immunotherapy, which uses the immune systems of the patients to identify and eliminate cancer cells.

Some immunotherapy medications, such as pembrolizumab (Keytruda) and nivolumab (Opdivo), function by preventing the mechanism by which cancer cells can conceal themselves from the immune system.

These immune checkpoint inhibitors, also known as anti-programmed death (PD-1) medications, are successful in treating roughly 50% of patients with melanoma, a kind of skin cancer.

Recently, researchers investigated whether patients with metastatic melanoma might respond better if immunotherapy and fecal microbiota transplants were combined.

This combination was not only risk-free but most patients responded well to the therapy, with some obtaining complete remission.

Phase 1 of the trial

Faecal transplants were coupled with the licenced medications pembrolizumab or nivolumab, which are already the standard of care for advanced melanoma, in the phase 1 MIMic trial.

The objective of the clinical experiment was to determine whether it is secure to combine these two medications in melanoma patients. As a supplementary goal, the impact of faecal transplants on the immune system and gut flora was evaluated.

Following a technique that was approved by Health Canada, healthy donors were carefully chosen. Then, capsules were created using the faeces of healthy donors.

Twenty metastatic melanoma patients were enrolled in the trial from Lawson Health Research Institute, the Jewish General Hospital (JGH), and the Centre Hospitalier de l’Université de Montréal (CRCHUM).

Each research subject was given capsules containing 80–100 mg of a fecal transplant from a single healthy volunteer donor. At least a week before receiving treatment with approved immunotherapy medications (either pembrolizumab or nivolumab), the fecal transplants were administered orally as capsules.

Is fecal transplantation plus immunotherapy safe?

The faecal transplantation operation was successfully completed by each of the 20 patients.

No major side effects were noticed prior to beginning immunotherapy, and no infections were spread through faecal transplantation. However, eight patients (40%) did have mild to moderate side effects from faecal transplantation, including diarrhoea, flatulence, and abdominal discomfort.

17 patients (85%) of the group encountered adverse immune-related events, the majority of which (70%) happened within the first three months of immunotherapy. Of these, five study participants (25%) experienced significant immune-related adverse effects, including nephritis (n = 1), arthritis (n = 2), exhaustion (n = 1), pneumonitis (n = 1), and arthritis (n = 2). These side effects forced the study participants to stop receiving their medication.

The researchers found no previously unreported adverse reactions to immunotherapy or faecal transplantation.

Did combined therapy lead to better results?

Four of the 20 participants in the trial (20%) experienced complete remission, making up 65% (13 out of 20) of the patients who responded favorably to the therapy.

All patients had strains of the donor’s bacteria in their gut microbiomes, according to analysis; however, this resemblance only got stronger over time in those patients who had a good response to the therapy. After receiving faecal transplants, respondents had higher levels of helpful bacteria and lower levels of dangerous bacteria.

The good impact of healthy donor faeces in boosting the efficiency of immunotherapy was further demonstrated in studies on mice by the researchers.

Fecal microbial transplantation: what is it?

Fecal transplantation, also known as fecal microbial transplantation (FMT), is a medical treatment in which the recipient’s intestines are filled with a healthy person’s donated poo (or feces).

In order to address medical disorders linked to abnormalities in gut bacteria, this method involves introducing healthy bacteria into the recipient’s intestines.

The effective treatment for recurrent Clostridium difficile infections is fecal transplantation. Fecal transplants are frequently administered via colonoscopy, however they can also be given as pills.

Gut and immune system interaction

So why do immune checkpoint inhibitors not work for everyone?

Recent research reveals that the bacteria in the gut may have an impact on how well the medications work. Immune checkpoint inhibitor-responsive individuals have a distinctive and healthy gut microbiome, often known as a “group of microorganisms in their gut.”

One of the study’s authors, Saman Maleki, Ph.D., assistant professor of oncology, pathology and laboratory medicine, and medical biophysics at Western University, as well as a researcher at the London Regional Cancer Programme and Lawson Health Research Institute, reasoned that altering a person’s gut microbiome to make it more diverse and healthy may enhance their response to immune checkpoint inhibitors.

Faecal microbial transplantation is one technique to modify the gut microbiota.

Will fecal transplants be used in the management of melanoma?

The principal study investigator, Dr. John Lenehan, a medical oncologist at the London Regional Cancer Programme, an associate scientist at the Lawson Health Research Institute, and an associate professor of family medicine and oncology at Western University, stated that the most significant finding in the study was that “none of the patients were harmed by the experimental treatment.”

Faecal transplants had been demonstrated to be beneficial by observational and pre-clinical studies, but “what happens in mice does not always translate to patients,” he noted. In fact, according to Dr. Lenehan, “more recent studies using similar therapies have shown harm, with patients having a worse response.”

He clarified that faecal transplantation was carried out differently in these other investigations than it was in the MIMic experiment.

“There are several factors, including bowel preparation, the number of FMTs required, the amount of stool required, and the identity of the donors. We had no idea if our approach would be secure or efficient. Thankfully, it appears that it was both! “, he exclaimed.

The director of the Supportive Oncology Research Group at the University of Adelaide and a research fellow at the Hospital Research Foundation Group, Hannah Wardill, Ph.D., who was not involved in this study, thinks this combination therapy strategy has the potential to be a successful treatment.

“FMT is a reasonably accessible intervention, and this study shows it is safe and likely effective at improving immunotherapy response,” she added.

The combination of faecal transplants and immunotherapy results in an improved response rate in patients who would otherwise be unresponsive to immunotherapy, which indicates that “more people will benefit from immunotherapy,” according to Dr. Wardill.

Boost skin cancer immunotherapy by targeting proteins.

Boost skin cancer immunotherapy by targeting proteins.

Comments 0 Comment

A protein that aids tumors in evading immune response and supports the growth of melanoma has been discovered by new research.

According to researchers, immunotherapy should be more effective with tailored medicines directed particularly at this protein.

One of the most prevalent malignancies, melanoma is typically brought on by exposure to UV light, while hereditary factors also play a part in its development.

Experts advise staying away from tanning beds and direct sunshine, as well as keeping an eye out for any moles that seem out of the ordinary.

The growth of melanoma has been the subject of recent research, which has also opened up new potential treatment options.

In a study that was published in the journal Science Advances, researchers showed how a protein called NR2F6 aids tumor growth by assisting tumours to elude the immune system.

The scientists discovered that in mice, eliminating the protein made the immune treatment work more effectively.

“This tells us that NR2F6 helps melanoma evade the immune system, and without it, the immune system can more readily suppress tumour growth,” said Dr. Hyungsoo Kim, a research assistant professor at Sanford Burnham Prebys, a research centre in La Jolla, California, and the study’s first author.

Treatments that prevent the protein’s action are thought to be twice as effective since it behaves the same way whether it is in a tumor or the tissues around it.

The scientists are currently searching for fresh medications that can particularly target NR2F6.

learning about melanoma

Melanoma develops when the DNA in skin cells is harmed, according to dermatologist Dr. Ahmad Chaudhry of the United Kingdom, who spoke to us.

According to Chaudhry, exposure to ultraviolet (UV) light from the sun or tanning booths is frequently to blame for this. “Due to this damage, the melanocytes (cells that produce melanin) proliferate out of control and aggregate into a mass of malignant cells. The development of melanoma in the eyes or internal organs does occur occasionally, but it is less frequent.”

While there are some hereditary risk factors that can potentially play a role, sunshine and tanning beds are linked to skin cancer for a reason.

We were informed by Dr. Sudarsan Kollimuttathuillam, a medical oncologist and haematologist at the City of Hope cancer research organization’s Huntington Beach and Irvine Sand Canyon locations, that 7% to 15% of people with melanoma also have a family member who has the condition.

According to him, having characteristics like pale skin, freckles, or blonde or red hair raises one’s overall risk of developing skin cancer. Atypical mole syndrome is another genetic disorder that dramatically raises the lifetime risk of melanoma and is characterized by a high number of moles with odd forms or color.

Risk can be reduced, but genetics cannot be changed. Doctors advise limiting exposure to the sun during peak hours, staying away from tanning beds in general, and wearing sun protection when outdoors to reduce your risk of acquiring skin cancer.

In the words of Kollimuttathuillam, “regular skin examinations by both you and a dermatologist will help detect melanoma at an early stage, when it is more treatable.”

Experiencing melanoma

One of the most prevalent types of cancer are skin malignancies like melanoma.

More than 97,000 Americans are expected to receive melanoma diagnoses in the US in 2023, according to the American Cancer Society.

As previously mentioned, melanoma can be detected early by a number of telling indications, including genetics and moles. The following procedure usually entails removing and then examining the mole if a doctor suspects it may be malignant. Melanoma presence or absence can be assessed by a range of tests.

It’s crucial to get an early diagnosis of melanoma because it spreads quickly.

According to Kollimuttathuillam, melanoma is the type of skin cancer that is most likely to spread to distant organs or bones. Because of this, imaging technologies may be utilized to spot cancer cells that have done so.

After receiving a melanoma diagnosis, a patient has a variety of treatment choices at their disposal, including radiation therapy, surgery, and immunotherapy.

In the earliest stages of melanoma, patients typically do not require imaging tests because, as Kollimuttathuillam noted, “we know that the best way to stop cancer is to prevent it.” “I cannot emphasize enough how crucial it is for patients to be advocates for their skin health to avoid advanced stages of this disease,” the doctor said.

Types of Immunotherapy

Medication is used in immunotherapy to boost your immune system. This might aid in its attack on cancer cells.

Severe melanoma is treated with a variety of immunotherapies, including:

Checkpoint blockers. The PD-1 blockers nivolumab (Opdivo) and pembrolizumab (Keytruda) as well as the CTL4-blocker ipilimumab (Yervoy) are among these drugs. These medications could aid T cells in your immune system in identifying and eliminating melanoma cancer cells.

Oncolytic virus therapy. In this procedure, melanoma tumors are injected with talimogene laherparepvec (T-VEC, Imylgic), a modified virus. In addition to killing cancer cells, this virus may also cause your immune system to fight cancer cells.

Cytokine therapy. Immune cells can interact with one another with the aid of a class of proteins called cytokines. Interleukin-2 (aldesleukin, proleukin) therapy may enhance your immune system’s defense against cancer.

Your doctor may recommend a single immunotherapy treatment or a cocktail of immunotherapy medications. They might prescribe Yervoy and Opdivo combined, for instance.

Individuals with stage 4 melanoma now have better survival rates thanks to immunotherapy. However, there is a chance that this treatment will have negative side effects.

Contact your doctor straight away if you suspect any potential side effects.

In order to combine medication with diagnostics, researchers have found a novel radioactive compound named CB-2PA-NT as a possible possibility.

The chemical exhibits strong uptake and retention in tumors while maintaining a distinct difference from surrounding tissues. It works by targeting neurotensin receptors, which are prevalent in numerous malignancies.

Shortly, researchers intend to carry out human imaging investigations utilizing CB-2PA-NT, which may have an impact on personalized cancer treatment for patients. Regulatory approval is still waiting.

The University of Wisconsin and the University of North Carolina worked together to create the anti-cancer medication candidate CB-2PA-NT, which has the potential to be used widely.

This study lays the framework for future investigations that will use CB-2PA-NT in human imaging, albeit these studies still require regulatory approval in order to start.

New research positions CB-2PA-NT as a promising candidate for an original theranostics method, according to data presented at the Society of Nuclear Medicine and Molecular Imaging Annual Meeting (SNMMI 2023).

Therapy and diagnostics are combined in theranostics.

Correct diagnosis is a prerequisite to choosing the best course of action. A precise diagnosis is even more crucial in the era of personalized medicine. This is where treatments can be tailored to a person’s unique biomarkers.

This is especially true in the field of cancer, where it is crucial to get a precise diagnosis.

Theranostics offers a potent method for battling cancer by fusing two crucial components. It entails locating cancer cells throughout the body and removing them with specialized radiation.

Positron emission tomography (PET) is used to localise the malignancy, and then medicine is given to kill it. Theranostics’ astounding accuracy greatly reduces the possibility of damaging nearby healthy tissues.

CB-2PA-NT has the potential to significantly advance the field of precision medicine by particularly targeting neurotensin receptors (NTSRs) present in diverse cancer types.

Researchers pursue the receptors on cancer cells

When it comes to many malignancies, including lung, colorectal, breast, pancreatic, and prostate cancers, NTSRs are more prevalent receptors.

A radioactive chemical that can precisely bind to NTSR1, one of these receptors, has been developed by scientists.

In terms of how well they are absorbed and retained by tumors, earlier attempts to synthesize these compounds have had mixed results.

One of the study’s authors and doctorate candidate at the University of North Carolina in Chapel Hill, Xinrui Ma, gave us an explanation of the main conclusions.

“This [study] abstract reports] a novel theranostic agent targeting neurotensin receptor 1 (NTSR1) and its application in cancer imaging and therapy,” said Ma.

The optimization of NTSR1-related compounds has already been attempted by numerous organizations, including our own. In fact, we have been working on this topic since 2012. Challenges include limited serum stability, significant liver absorption, some ligands’ agonistic character, and/or quick washout, she added.

The cross-linked propylamine moiety, Ma continued, “can significantly improve tumor uptake and retention, building on previous research and experience.”

“The tumor absorption increased 10-fold as compared to the peptide-based ligand while still maintaining the high contrast. The high uptake was also sustained at 24 and 48 hours following injection, which is more significant, the researcher said.

We have a rare chance to create theranostic drugs for patient treatment because of the much better tumor absorption and retention. Indeed, to investigate the theranostic potential of these novel compounds in a variety of cancer types, such as lung cancer, colorectal cancer, and PSMA-negative prostate cancer, we have forged a close partnership with Prof. Jonathan Engle’s team at the University of Wisconsin, said Xinrui Ma.

Which NTSR1 inhibitor is most effective?

The best NTSR1 antagonist for imaging and therapy was determined by the researchers’ investigation, which looked at a variety of NTSR1 antagonists.

They then carried out studies to radioactively designate these compounds. They verified that the NTSR1 receptor was in fact present in the lung cancer cells (H1299 cells) using a procedure known as western blot.

The compounds were also examined for stability in test tubes and on living lung cancer cells. Also, for their capacity to bind to lung cancer cells in laboratory settings and on animals.

Finally, to examine how the chemicals were dispersed throughout the body, they used PET and CT imaging on tiny animals.

Western blot analysis of the results revealed that the NTSR1 receptor was substantially expressed in the H1299 lung cancer cells. The chemical known as CB-2PA-NT has shown a potent ability to bind to the H1299 lung cancer cells among the NTSR1 antagonists.

Small animal imaging provided proof that CB-2PA-NT was taken up by the tumor in large numbers. Clearly contrasted with the surrounding tissues, and stayed in the tumor for a considerable amount of time.

CB-2PA-NT was chosen for additional research because it stood out as the most promising compound when compared to the other NTSR1 antagonists.

There is a “need to confirm application in humans”

If this theranostic strategy is successful, it may provide a reliable method for imaging to detect the presence of NTSR1 in many cancer types.

This would be helpful for making diagnoses, selecting patients, and keeping track of how well treatments were working. It might also function as a radioactive material used in therapy.

We were informed by Yale resident doctor Dr. Tejasav Sehrawat. He was unrelated to the experiment, that “theranostics is a young discipline for diagnosing and treating malignancies. The growth of the field overall is quite intriguing and has a lot of potential. The competent execution of this investigation and the good preclinical findings are encouraging.

“While the authors have already demonstrated their findings in animal models, application in people still has to be verified. We should all be eagerly awaiting the findings of the authors’ next human investigations. Because there is significant inter-species heterogeneity in these studies, according to Dr. Tejasav Sehrawat.

Possibly negative future effects for cancer patients

This finding, according to Ma, “is important because it could offer personalised medicine for cancer patients,”

She informed us that, in terms of the disease, NTSR was discovered to be overexpressed in prostate cancer tissues. Specifically in PSMA-negative prostate cancer tissues.

This shows that NTSR1-targeted theranostics may be a prostate cancer treatment option in populations that are ineligible for PSMA-based methods. Lung, colorectal, breast, and pancreatic cancers are only a few of the tumors that could potentially benefit from NTSR-targeted theranostics, says Ma, Xinrui

“A broad spectrum of patients may benefit from the newly developed agents,” Ma noted. The researchers are still awaiting regulatory authorization to carry out the first-ever human imaging tests with CB-2PA-NT, and more study is required.
