Abstract
Dermatofibrosarcoma protuberans (DFSP) is a rare indolent cutaneous tumor; approximately 10–15 % contain areas of fibrosarcoma (DFSP-FS) and tend to behave more aggressively. The optimal treatment is resection with wide margins; the likelihood of local control after this procedure exceeds 90 %. Patients with positive or close margins have a high risk of local recurrence after surgery alone; the addition of postoperative radiotherapy results in local control rates of 85 % or higher. The dose-fractionation schedules are similar to those used for carcinomas. Experience with radiotherapy alone for gross disease is limited. The probability of regional or distant metastases is 5 % or less.
