[Long-term experience with multidisciplinary therapy of twenty-six patients with dermatofibrosarcoma protuberans].
2009
Abstract Dermatofibrosarcoma protuberans is a low or moderate grade malignant, uncommon soft tissue tumor. The tumor is characterized by slow, but locally aggressive growth, low metastatic potential and high recurrence rate. Initial treatment is the radical surgical excision, using traditional wide excision or Mohs surgery. In case of positive surgical margin or local recurrence, radio-chemotherapy and recently imatinib mesylate is used as adjuvant therapy. Twenty-six patients treated multidisciplinary for dermatofibrosarcoma protuberans were followed up. Mean age of the patients was 44.7 years; mean follow-up time was 60.57 months. In fifteen cases (57.7%) R0 resection was performed, while eleven patients (42,3%) received only R1 resection. An average of 1.87 resections was necessary in order to achieve R0 resection. Six patients (23%) received adjuvant radiotherapy and two patients (7.6%) adjuvant chemotherapy following the removal of the primary tumor. Sixteen patients had no local recurrence. Ongoing treatments were needed in the case of ten patients (38.4%) who developed local recurrence. One patient has deceased due to distant metastases. Using statistical methods we examined the effects indicated as prognostic factors in the literature on local recurrence, precisely, the effect of age above 50 years and surgical radicalism. Dermatofibrosarcoma protuberans can be successfully treated with multidisciplinary therapy. A larger number of cases and randomized multicenter investigations are needed in order to reach more accurate conclusion.
