Conclusions

• IMRT superior to 3DCRT for locally advanced NSCLC

– lower dose to all risk organs except low dose to lungs

• Interplay effects not really critical in IMRT

– gated delivery not crucial for IMRT

– but start off with ‘simple’ plans with large segment shapes

– additional respiration margin of about ¼ amplitude (if GTV is

delineated at mid-vent CT)

• Start working on a sound IGRT protocol before going into

optimizing your planning procedures
