N2 - Purpose: Assessing predictors of acute bowel toxicity after whole-pelvis irradiation (WPRT) Image-guided Tomotherapy with simultaneous integrated boost on prostate/prostate bed. Methods and materials: In the period March 2005-April 2009, 178 patients were treated with radical or adjuvant/salvage intent with WPRT Tomotherapy. Median dose to the pelvic nodes was 51.8 Gy/28 fractions while concomitantly delivering 65.5-74.2 Gy to prostate/prostatic bed. The impact of many anatomical and clinical parameters on ≥Grade 2 acute bowel toxicity was investigated by logistic analyses. Results: Only 15/178 patients (8.4%) experienced Grade 2 toxicity (none Grade 3). Main predictors at univariate analysis were nodal CTV (CTVN ≥ 380 cc; OR: 3.7, p = 0.017), treatment duration (
