Canyons and Volcanoes: The Effects of Radiation on the Chest Wall.

Tumors involving the sternum often require complete removal of the bony structure to achieve cure and prevent recurrence. The type and extent of reconstruction must be carefully selected. Full-thickness sternal defects often necessitate semirigid or rigid biocompatible prostheses and carefully transposed myocutaneous flaps. Superimposed infection on radiation-induced cancer or osteoradionecrosis involving the sternum is also observed, and optimal treatment relies on an experienced multidisciplinary team. This report describes the successful management of 2 cases of sternal involvement after radiation: a canyonlike lesion and a volcanolike lesion.
