The main methods of treating prostate cancer are surgery, endocrine therapy, radiotherapy and chemotherapy. Depending on the clinical stage of prostate cancer, there are also differences in treatment methods. Stage I means the tumor is not obvious, cannot be palpated or not detected by imaging; 2. Stage II means the tumor is confined to the prostate; 3. Stage III means the tumor is beyond the prostate envelope; 4. Stage IV means the tumor is fixed or invades the adjacent tissues other than the seminal vesicles. Generally, radical prostatectomy is preferred for stage I and II prostate cancer. A few patients with stage III and IV prostate cancer can be considered for radical prostatectomy after strict screening. Radical prostate cancer surgery is one of the most effective ways to cure limited prostate cancer. Early screening can give prostate cancer patients the opportunity to undergo radical surgery, which is one of the most effective ways to treat limited prostate cancer. Stage III prostate cancer is treated with a combination of endocrine therapy. Most prostate cancers are effective in removing androgens from the body, and treatment includes surgical debulking and drug debulking. Surgical debulking refers to the removal of testicular tissue in men; pharmacological debulking refers to the use of drugs to block androgens, commonly used drugs such as Norelide and Comstock. In addition, radiation therapy is also an option, with radioactive particle implantation and external radiation treatment for prostate cancer. For stage IV prostate cancer, endocrine therapy combined with radiotherapy is the main treatment, and chemotherapy can be administered to patients with desmoid-resistant prostate cancer.
