Pelvic OARs constraints: sparing the bowel
- V15 as strong predictor in a recent updated model by Robertson (2010)
- Not confirmed in the NRG0822 controlled trial (!)…WHY ?
- Robertson study: 3DCRT 3 fields (pre & post-op)
- NRG0822: IMRT (pre-op)
- Robertson study: bowel loops
- NRG0822: «peritoneal space»
- Correlation between V40-V45 and V15 for 3DCRT
