A Multileaf Collimator for Modulated Electron Radiation Therapy for Breast Cancer

Abstract

Results from recent clinical trials have shown that irradiation is an effective adjuvant therapy to lumpectomy, mastectomy, and chemotherapy for breast cancers of different stages. However, the conventional tangential photon beam treatment has two major limitations. Firstly, part of the lung and heart (in the case of the left breast treatment) may be exposed to high radiation dose. Secondly, the contralateral breast may receive a significant amount of scatter dose. Consequently, irradiation-related complications such as arm edema, myocardial infarction, severe breast fibrosis, and secondary breast cancer may occur in the patients who have undergone conventional photon beam treatment.
