For early prostate cancer endocrine therapy is more effective. Androgen is closely related to the occurrence and development of prostate cancer, and endocrine therapy is one of the important treatments for prostate cancer. The indications of endocrine therapy are: metastatic prostate cancer (N1 and M1); limited early prostate cancer or locally progressed prostate cancer, which cannot be treated with radical surgery or radiotherapy; neoadjuvant endocrine therapy before radical surgery or radical radiotherapy; adjuvant endocrine therapy with radiotherapy; local recurrence after curative treatment, but unable to undergo local treatment; distant metastasis after curative treatment; androgen continuous suppression during the stage of denervation resistance. .. Some studies claim that the 1-, 3- and 5-year disease-specific survival rates of prostate cancer patients after endocrine therapy are 93.2%, 68.3% and 40.1%, respectively. If prostate cancer is suspected or diagnosed, it is recommended to go to regular hospitals for a comprehensive assessment of the condition and follow the doctor’s instructions for treatment to avoid delays.
