Primary Outcome Measures
NameTimeMethod
Histopathological response to 177Lu-PSMA RLT in the resected prostate specimen and in the resected lymph nodes
Secondary Outcome Measures
NameTimeMethod
-To study the tolerability of study medication and assessment of quality of life (QoL) by patient reported outcome measures and specific QoL questionnaires using the EORTC Quality of Life Questionnaire for cancer patients (EORTC-QLQC30 and EORTC-QLQ-BM22) [19] at baseline and four weeks after each cycle of 177Lu-PSMA RLT.<br><br>-To assess the prostate-specific antigen (PSA) free survival at 12 months after two cycles of 177Lu-PSMA RLT and concurrent RARP and ePLND.<br>
