Using previous dosimetric analysis methods, we identified the volume of bowel receiving 30 Gy (V30) correlated with acute gastrointestinal (GI) toxicity in anal cancer patients treated with intensity-modulated radiation therapy and concurrent chemotherapy. For V30 > 450 cc and ≤450 cc, acute GI toxicity was 33% and 8%, respectively (p = 0.003).
