BACKGROUND AND PURPOSE: This study reports on the treatment techniques, toxicity, and outcome of pelvic intensity-modulated radiotherapy (IMRT) for lymph node-positive prostate cancer (LNPPC, T1-4, c/pN1 cM0). PATIENTS AND METHODS: Pelvic IMRT to 45-50.4 Gy was applied in 39 cases either after previous surgery of involved lymph nodes (n = 18) or with a radiation boost to suspicious nodes (n = 21) with doses of 60-70 Gy, usually combined with androgen deprivation (n = 37). The prostate and seminal vesicles received 70-74 Gy. In cases of previous prostatectomy, prostatic fossa and remnants of seminal vesicles were given 66-70 Gy. Treatment-related acute and late toxicity was graded according to the RTOG criteria. RESULTS: Acute radiation-related toxicity higher than  grade 2 occurred in 2 patients (with the need for urinary catheter/subileus related to adhesions after surgery). Late toxicity was mild (grade 1-2) after a median follow-up of 70 months. Over 50% of the patients reported no late morbidity (grade 0). PSA control and cancer-specific survival reached 67% and 97% at over  5 years. CONCLUSION: Pelvic IMRT after the removal of affected nodes or with a radiation boost to clinically positive nodes led to an acceptable late toxicity (no grade 3/4 events), thus justifying further evaluation of this approach in a larger cohort.
