Age
18 Years to 85 Years

Inclusion criteria

Inclusion criteria: 1) Aged =18 and =85 years. 2) Pathologically confirmed prostate cancer, excluding pure small cell carcinoma or sarcoma, but allowing inclusion of patients with partial neuroendocrine differentiation. 3) PSMA PET confirmed the presence of 1-3 bone metastases, with regional lymph node metastasis allowed (lymph node metastasis within the abdominal pelvic cavity below the bifurcation of the abdominal aorta). If PSMA PET was not performed at diagnosis, bone scan confirmation of 1-3 bone metastases is allowed, but a PSMA PET must be reviewed before enrollment. 4) Prior systemic treatment (endocrine therapy, chemotherapy, targeted therapy, radionuclide therapy) before enrollment is permitted. 5) No history of pelvic radiotherapy, external beam radiotherapy to the prostate, or brachytherapy, or radical prostatectomy. 6) ECOG performance status of 0-2. 7) Agreement to enroll and sign an informed consent form. 8) Ability to comply with radiotherapy positioning and treatment. 9) Ability to complete quality of life questionnaires. 10) Laboratory tests meet the following criteria.

Exclusion criteria

Exclusion criteria: 1) History of external beam radiotherapy or brachytherapy to the primary lesion, or history of radical prostatectomy. 2) Non-regional lymph node metastasis and/or visceral metastasis confirmed by PSMA PET/CT/MR within 90 days prior to randomization. 3) Progression to the hormone-resistant stage (mCRPC). 4) Subjects deemed unsuitable for participation in the clinical trial by the investigator.
