Brief Summary:
The optimal treatment for oligometastatic prostate cancer (OMPC) is still on its way. Accumulating evidence has proven the safety and feasibility of radical prostatectomy and local or metastasis-directed radiotherapy for oligometastatic patients. The aim of this trial is to compare the safety and feasibility outcomes of metastasis-directed neoadjuvant radiotherapy (naRT) and neoadjuvant androgen deprivation therapy (naADT) followed by robotic-assisted radical prostatectomy (RARP) to ADT combined with abiraterone for treating OMPC.
Detailed Description:
The present study will be conducted as a prospective, open-label, two arms clinical trial. Patients with ≤ 3 de novo oligometastatic PCa, diagnosed on Ga-68 prostate-specific membrane antigen (PSMA) PET/CT, will be randomized in a 1:1 ratio between arm A (hormone) and arm B (neoadjuvant hormone and RT). The patients in arm A with oligometastatic PCa will receive long-term ADT combined with abiraterone. The patients in arm B with oligometastatic PCa will receive 1 month of naADT, followed by metastasis-directed radiation and abdominal or pelvic radiotherapy. Then, radical prostatectomy will be performed at intervals of 5-15 weeks after radiotherapy, and long-term ADT will be continued. The primary endpoints of the study are progression-free survival (PFS) including biochemical recurrence-free survival (bPFS), and radiological progression-free survival (RPFS). The secondary endpoints include quality of life (QoL), time to CRPC, positive surgical margin (pSM), overall survival (OS), postoperative continence, and toxicities parameters.
