Morbidity dynamics in proton –photon or photon radiation therapy for locally advanced prostate cancer

Conclusions Local irradiation with a fractional dose of 3.0–5.5Gy(RBE) and a cumulative dose of 28.0–28.8Gy(RBE) for protons significantly reduces the early and late rectitis severity, but does not reduce the risk of lower urinary tract injuries. Fractionation regimens do not significantly differ in toxicity levels.
