Lower GI 2017

Conclusive remarks

- 3DCRT and IMRT techniques offer good planning solutions - IMRT should be preferred (better sparing of OARs, better conformation) - Risk of sub-optimal planning with IMRT, be careful…. - Rotational IMRT (VMAT/IMAT/RA…., Tomo) highly effective and fast, better conformality and, sometime, better OAR sparing - Constraints for OARs still poorly available (primarily for bowel, bone marrow, genitals)….much to be done (need of studies correlating prospective patient-reported outcomes/QoL scores vs dose-volume data) - (Quantification of the impact of CHT poorly addressed)

- IGRT improves accuracy; potentials to reduce margins with the aim to spare OARs in specific patients (i.e: sexual dysfunctions ?) - Adaptive re-planning in its very early phase…
