Conclusion: The bladder wall V25Gy was significantly higher in the group with acute GU toxicity as predicted by earlier work. Indeed, in the group with Gr2+ toxicity the constraint V25Gy > 9 cc was violated 3 times as often as without toxicity. Further investigations are ongoing to explore the unexpected result of no significant difference in GU toxicity patterns between the tight and standard margin groups.
