Patients with prostate cancer at age 80 can generally live for more than five years with treatment. For male patients, prostate cancer is an age-related disease that generally develops slowly and has a long course. For patients over the age of 75, radical prostate cancer surgery is not recommended. 80-year-old prostate cancer patients are recommended to have endocrine therapy or radiotherapy. For this condition, an effective survival time of more than 5 years can be obtained with the above mentioned treatment options. Endocrine therapy for prostate cancer is very effective. It is recommended to take oral Comstock 50mg per day for 28 days per month orally as a course of treatment. Continuous treatment for 9-12 months can effectively control the progression of prostate cancer and effectively prolong the survival time of patients.
