A Phase II Randomized Study of Proton Versus Photon Beam Radiotherapy in the Treatment of Unilateral Head and Neck Cancer

Memorial Sloan Kettering Cancer Center·interventional·Posted Oct 4, 2016·Updated Nov 5, 2025

In Brief

A Phase 2 clinical trial evaluating Photon intensity modulated radiation therapy (IMRT) and Proton beam radiotherapy (PBRT) for Head and Neck Cancer. Active but no longer recruiting, targeting 108 participants across 9 sites.

Detailed Summary

Compared to IMRT, PBRT is thought to give less radiation exposure to the surrounding healthy tissues. It is possible that side effect rates with PBRT will be lower or the same compared to IMRT, but this has not been well studied to date. Although both of these radiation therapies have been used in the past to treat head and neck cancer, this research study will compare the effects of these two different radiation treatment modalities with each other to see whether PBRT is better, the same or worse than IMRT.
