68Ga-PSMA-11 Efficacy in Detecting BCR Prostate Cancer in Chinese Patients

This study is testing a special type of imaging scan using a radioactive tracer called 68Ga-PSMA-11 to see how well it can detect prostate cancer that has come back after surgery or radiation treatment in Chinese patients. A rising PSA blood test after initial treatment can signal recurrence, but standard scans often can't find where it is — this PET scan may do better. **You may be eligible if...** - You are a Chinese male aged 18 or older - You have a confirmed diagnosis of prostate cancer and have been treated with surgery or radiation - Your PSA (a blood marker for prostate cancer) has risen again after treatment, suggesting the cancer may have returned - You are willing to undergo the imaging scan **You may NOT be eligible if...** - You have not had prior radical prostatectomy or radiotherapy - You are currently receiving hormone therapy or other systemic prostate cancer treatment - You have had another cancer in the past 5 years - You are unable to provide consent Talk to your doctor to see if this trial is right for you.
