Advances in Ovarian Cancer Treatment and Prevention Mechanisms Can Save Many Women in India : Fortis Hospital
News Desk, News Nation 360 : Women-related cancers although being one of the major causes of mortality in India are less spoken about and cared for. Cancers such as ovarian cancer especially have a high mortality rate. In India, 59,276 were estimated as new ovarian cancer cases at the end of 2020. The incidence of ovarian carcinoma is expected to increase to 371,000 a year by 2035 (55%) increase, while the death rate increases by 67% to 254,000. Moreover, women in the perimenopausal age group and in their 50s and 60 years are more likely to develop ovarian cancer. Dr Sujata Datta, Consultant, Mother & Child Care, Fortis Hospital Anandapur Kolkata has spoken about it. The first step is to diagnose the disease using symptom history, physical examination, imaging techniques and tumour markers. There are different types of imaging like ultrasound, MRI, CT scan that examine the spread of the disease and the current stage and type of tumour. The next step is deciding whether surgery or adjuvant therapy such as chemotherapy is appropriate as the initial step in treatment. The age of the patient, type and stage of tumour and to some extent her fertility plans determines the type of surgery done. In young patients, with certain early-stage germ cell tumours that have low malignant potential, and whose families have not been completed, conservative surgery with removal of the affected ovary only sometimes performed. For patients with advanced-stage ovarian cancer, sometimes a few cycles of chemotherapy are given first to shrink the disease and then surgery is performed to reduce complications and morbidity from the procedure. In the last few decades, there have been phenomenal advances in ovarian cancer treatment and genetic testing has played a significant role in providing personalized treatment. For example, to assess the risk of cancer in a woman with a family history of breast and ovarian cancer, BRCA 1 and BRCA 2 genetic testing are often done. If the result is positive then the risk of ovarian cancer is very high, almost 45%. In such cases, women are advised to have their ovaries and tubes removed after childbearing or by the age of 35-40, to minimise the risk of later developing ovarian cancer and also reducing the incidence of breast cancer. Other ways to reduce the risk of ovarian cancer are the use of the oral contraceptive pill and breastfeeding. Tubal ligation and removal of tubes surgically also helps reduce the risk of ovarian cancer. Moreover, a large majority of women then undergo a staging laparotomy that consists of adequate midline incision, meticulous exploration of the abdominal cavity and organs with biopsies as required. Fluid from the abdominal cavity is sent for cytology, and removal of the uterus with both ovaries and tubes are carried out together with pelvic and paraaortic lymph nodes removal and excision of the fatty apron called the omentum. Now, many people are not aware that 1 in 4 women with ovarian cancer has a hereditary mutation. Ovarian cancer has a high percentage of genetic mutations that are hereditary compared with other cancers like breast cancer. Therefore, any patient with a personal history of breast cancer diagnosed < 45 years, personal or family history of ovarian cancer, peritoneal cancer, or fallopian tube cancer should be sent for genetic counselling and tested for gene mutations. Moreover, women especially young girls and boys should be given the Human papillomavirus vaccine. This vaccine can prevent most cases of cervical cancer if given before a girl or woman is exposed to the virus. In addition, this vaccine can prevent vaginal and vulvar cancer in women and can prevent penile cancers in men.
