Objectives

Narrative objectives1

We hypothesize that pelvic lymph node prophylactic irradiation of PSA-nonresponders during treatment with PBRT will provide optimal salvage radiotherapy avoiding overtreatment, and we will evaluate the safety and efficacy of this treatment.

Interventions/Control_1

All patients will be prescribed 68 Gy to the prostate bed.
Patients are defined as responders and non-responders based on the change in PSA before radiotherapy and on the day of 46 Gy irradiation.
The responders will be completed at 68 Gy without field modification. The non-responders will be given extended field(pelvic wall radiation therapy)prescribed by 50 Gy.
Pre-treatment preparation period 1-14 days
Radiotherapy period 2 to 3 months
Post-treatment observation period 60 months.
