Dermatofibrosarcoma protuberans: treatment and prognosis

E J Rutgers et al. Eur J Surg Oncol. 1992 Jun.

Abstract

Dermatofibrosarcoma protuberans (DFSP) is a rare tumor of the skin with a strong tendency to recur locally. Nineteen cases of DFSP are presented. In eight of them a total of 20 local recurrences occurred, in five after irradical and in three after 'narrow' excisions. After wide excision (greater than 2 cm) for primary or wide re-excision for recurrent tumor, all patients remained free of tumor with a mean follow-up of 13.2 years (range 2-28 years). An extensive literature review revealed 913 cases of DFSP. The overall recurrence rate is about 50%; after adequate wide excision, 13%. Recurrent tumor is safely treated by wide re-excision and the recurrence rate is then 12%. Regional and distant recurrences are infrequent. Eleven cases (1%) were reported to have regional lymph node metastases and 37 (4%, 17 of whom were histologically confirmed) distant metastases, principally in the lung. The prognosis after appearance of regional or distant recurrence is bad. The role of radiotherapy in the management of this tumor is unclear. Primary or recurrent DFSP is best treated by surgical excision with a minimal margin of 2- preferably 3-cm of surrounding skin including the underlying fascia. Elective lymph node dissection is not advised.
