## TL;DR

Led the proton dose-escalation trial in prostate cancer and the comparative-effectiveness debate over proton therapy.

## Summary

Anthony Zietman led PROG 95-09, the randomised trial showing high-dose proton-boosted radiotherapy improves biochemical control in localised prostate cancer, and co-leads the PARTIQoL trial comparing protons with IMRT. He has championed evidence-based adoption of proton therapy, led bladder-preserving trimodality therapy at MGH, and edited the International Journal of Radiation Oncology, Biology, Physics.
