The treatment of lower extremity sarcomas with wide excision, radiotherapy, and free-flap reconstruction.
Treatment of extremity sarcomas has evolved into a multidisciplinary approach utilizing surgery, radiotherapy, and, in some cases, chemotherapy. Limb-sparing surgery has maintained low rates of local recurrence when supplemented with early postoperative radiotherapy (brachytherapy). Leg defects that result from resection resemble those caused by trauma and appear ideally suited to free-flap reconstruction. However, the resection site is subjected to 4500 cGy of radiation given within 2 weeks of surgery. It has not been demonstrated that free flaps can endure early postoperative radiation without adverse effects. Three patients are presented with locally recurrent leg sarcomas treated by wide excision, brachytherapy, and free-flap reconstruction. All flaps survived, and the wounds healed uneventfully. This study reviews the current multidisciplinary approach to the treatment of lower extremity sarcomas and demonstrates the durability of free-flap reconstruction in the presence of early postoperative radiation therapy.
