Does proton beam radiation therapy improve safety and disease control in patients with breast cancer requiring regional nodal irradiation?
Proton beam RT is safe and effective for breast cancer requiring regional nodal irradiation, with no early cardiac changes, supporting the need for randomized trials.
Proton beam RT for breast cancer has low toxicity rates and similar rates of disease control compared with historical data of conventional RT. No early cardiac changes were observed, which paves the way for randomized studies to compare proton beam RT with standard RT.
Jimenez et al. (Mon,) studied this question.
