Lower GI 2016

Conclusive remarks

- IMRT should be «mandatory» (better sparing of OARs, better conformation) - Quite strong evidence of clinical benefit using IMRT - Rotational IMRT (VMAT/IMAT/RA…., Tomo) highly effective and fast, better conformality and, sometime, better OAR sparing - Potential of IMRT not yet fully assessed, in particular for improving the sparing of genitals and bone marrow (a Phase II trial in progress) - Skin toxicity could be reduced (very sensitive to CTV/PTV definition, planning strategies) - IGRT /ART (?)
