To investigate the efficacy and toxicity of 68Ga-PSMA-HBED-CC ((68)Ga-PSMA) PET-CT-guided RT in the treatment of oligometastatic prostate cancer retrospectively.
A total of 23 prostate cancer patients with biochemical relapse, of which 13 were castration sensitive (CS) and 10 castration resistant (CR), were treated with intensity-modulated and image-guided RT (IMRT-IGRT) on ≤3 metastases detected by (68)Ga PSMA PET-CT.
