Computer-aided treatment design of a distal upper extremity soft tissue tumor with electron beam radiotherapy

We present here a novel approach for the planning and treatment of a distal upper extremity soft tissue tumor. Utilizing computed tomography (CT) based electron dose calculations, a customized compensating wax bolus was designed in order to deliver sufficient dose coverage to the tumor volume while sparing the draining lymphatics of the patient's hand and digits. A clinical case is presented as well as the design and construction of the compensator. Outcome and clinical implications are discussed.
