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.
