Opinion statement

When treating soft tissue sarcomas (STS) of the extremities, the major therapeutic goals are survival, local tumor control, optimal function, and minimal morbidity. Surgical resection of the primary tumor is the essential component of treatment for virtually all patients. However, local control by surgery alone is poor for the majority of patients with extremity lesions unless the procedure removes large volumes of grossly normal tissue (ie, widely negative margins are attained, because sarcomas tend to infiltrate normal tissue adjacent to the evident lesion). Thus, removal of the gross lesion by a simple excision alone is followed by local recurrence in 60% to 90% of patients. Radical resections reduce the local recurrence rate to 10% to 30%, but may compromise limb function. The combination of function-sparing surgery and radiation achieves better outcomes than either treatment alone for nearly all patients with STS. Because both surgical and radiation technique are critically important for optimizing local control of tumor and functional outcome, it is important to manage these patients in dedicated multispecialty clinics comprised of physicians with expertise in sarcomas, including orthopedic and general oncologic surgeons, radiation oncologists, medical oncologists, sarcoma pathologists, and bone and soft tissue diagnostic radiologists. Radiation therapy can be given by external beam radiation therapy (EBRT) or brachytherapy (BRT) or combination thereof. External beam radiation can be given either preoperatively or postoperatively. The clinical considerations and the outcome data that must be considered in choosing the most appropriate treatment technique for the individual patient are discussed.
