Inclusion criteria

Inclusion criteria: 1. Histologically confirmed prostate adenocarcinoma within the past 6 months; 2. Primary localized PCa (cN0 and cM0 on mpMRI and PSMA-PET); 3. PSMA-PET examination completed; 4. Good physical condition with an ECOG performance status of 0 or 1; 5. Age >= 18 years; 6. Expected survival >= 5 years; 7. Patient voluntarily participates, receives standard treatment prior to stereotactic body radiotherapy of the prostate, and signs the informed consent form.

Exclusion criteria

Exclusion criteria: 1. Prostate neuroendocrine tumor; 2. Previous history of prostate surgery, prostate or pelvic radiotherapy, or local prostate treatment; 3. Time interval between the start of ADT and the initial mpMRI and PSMA-PET scans is greater than 1 month; 4. Radiologically suspicious or pathologically confirmed mpMRI and/or PSMA-PET lymph node involvement (cN), metastatic disease (cM) / cT4 lesions; 5. Bilateral hip prostheses or any implants that may cause extensive CT artifacts; 6. Medication contraindications for undergoing mpMRI/PSMA-PET scans; 7.

New malignancies within the past 2 years, or previous malignancies expected to significantly affect 5-year survival; 9. Concurrent participation in other interventional clinical trials that may interfere with this study; 10. According to clinical assessment, anticoagulation therapy with warfarin or a bleeding tendency that poses a risk for fiducial marker implantation.
