Particle Therapy 2017

Strategies of RTOG-1308:

a)The prescribed dose for this study is 70 Gy. The study is designed to allow lower doses in situa;ons for which cri;cal structure constraints cannot be met. A>er randomiza;on the pa;ent’s dose will be individualized to the highest achievable dose (within normal ;ssue organs-at-risk constraints) between 60-70 Gy; b)Cross-over from protons to photons not permissable. c)The protocol will maintain strict organs-at-risk constraints for this trial; d)The protocol will perform preliminary quality assurance review as pa;ents are entered on the trial to monitor dose prescrip;ons and dose/contouring compliance.
