The treatment principles of prostate cancer vary with different stages. For clinical stage T1-T2N0M0 prostate cancer, which is early-stage, patients can choose radical prostatectomy or radical radiotherapy. For patients with locally advanced prostate cancer, specifically staged T3 or T4 but without lymph node or distant metastasis, options include radiotherapy combined with hormonal therapy or solely hormonal therapy. For patients with distant metastasis, which indicates advanced-stage prostate cancer, treatment primarily involves hormonal therapy. If hormonal therapy fails, chemotherapy may be utilized. Additionally, for pain caused by bone metastasis, local radiotherapy or radionuclide therapy can be integrated into the comprehensive treatment approach.
