Evaluation of the role of radiotherapy in the management of dermatofibrosarcoma protuberans
2013
Summary Purpose: The aim of this study was to evaluate the role of radiotherapy (RT) in the management of dermatofibrosarcoma protuberans (DFSP). Methods: Twenty-eight patients treated with RT for DFSP between 1974 and 2012 at Gulhane Military Medical Academy (GMMA) Radiation Oncology Department were retrospectively evaluated. Twenty-five out of 28 patients (89%) received postoperative RT and 3 received definitive RT alone. In the 25 patients receiving postoperative RT, the type of surgical excision was limited excision in 5 patients and wide excision in the remaining 20. Median RT dose was 63.21±3.7 Gy (range 50-70). Results: At a median follow-up of 5 years, 5-year overall survival (OS) for the whole patient group was 93%. No relationship was determined between the total delivered RT dose and OS. The 5-year OS of the 10 female patients was 90% whereas it was 94% for the 18 male patients (p>0.05). Five-year disease-free survival (DFS) for the patients undergoing wide excision with RT vs. those undergoing limited excision with RT was significantly superior (p <0.05) in patients treated with wide excision and RT. Conclusion: RT is an effective treatment option for DFSP patients with positive postoperative margins, recur rent disease and selected inoperable cases.
