A Clinical Analysis of 37 Cases Dermatofibroma Protuberans

From Jul 1977 to Oct 1989.37 cases of dermatofibroma protuberans(DFP)were treated either with surgery alone (S)or with surgery plus radiotherapy (S+R).The 3, 5, 7, 10, 15-years survival rates in two groupswere;S group 86.4%, 86.4%，63.6 %, 54.5%，4.5%and SCR group 100%, 93.3%，80%, 60%,33.3%Onlythel5-year survival rate was significant for the S+R group as compared to the S group. The 5-year disease free survival rate was significantly better for the S+R group as compared to the S group (P<0.01)either the first therapy or the secondary therapy after recurrence.The prognosis was better when the maximum tumor size was smaller than 7cm.Radiotherapy is recommended after expansive ontological resection in the light of the treatment of DFP.
