The five-year survival rate for patients with stage III endometrial cancer is about 50 percent after treatment, which varies from person to person. Endometrial cancer is a common malignant tumor in women, and the occurrence of the disease is related to hormone levels, obesity and many other factors. According to the FIOG staging, where stage III represents a situation where the tumor invades beyond the uterine body but does not extend beyond the true pelvis, and where the vagina and para-uterine tissues in the pelvis may be involved but not the bladder or rectum. For patients who are amenable to surgery, surgical resection is often performed; this is followed by adjuvant therapies such as radiotherapy. With aggressive treatment, patients with stage III endometrial cancer can achieve a five-year survival rate of about 50%. After surgery, it is important to follow the doctor’s instructions for regular checkups and maintain good living habits.
