Re-Irradiation with Conformal Electron Beam Therapy for Recurrent Breast Cancer

Patients with recurrent breast cancer involving the chest wall, who have been previously irradiated, present a clinical challenge. Pulsed reduced dose rate external beam radiotherapy has been shown to reduce recurrences with an acceptable rate of toxicity including chest wall soft tissue and rib necrosis [1]. For patients presenting with a breast cancer recurrence in close proximity to the skin surface, our treatment center has modified the technique by using electrons passing through customized wax bolus milled by a commercial compensator manufacturer (decimal, Sanford, FL).
