Alveolar soft part sarcoma: a report of 15 cases

The aim of this study was to evaluate the presentation, course and treatment outcome of 15 patients with this rare type of sarcoma. The files of the patients were retrospectively analysed. Overall survival was calculated according to the Kaplan-Meier method. There were 15 patients, 8 male and 7 female. The mean age at diagnosis was 29 years for men and 24 years for women. The median survival was 48 months with an overall 5-year survival of 38%. 5 patients had haematogenic metastases at the time of diagnosis. For the remaining 10 patients with localised disease, the median survival was 48 months and the 5-year survival 48%. The median disease-free survival for these patients was 12 months with a 5-year disease free survival of 40%. After the occurrence of haematogenic metastases, patients survived a median period of 8 months (range 0-45 months). 5 patients are still free of disease after a median period of 234 months (12-295 months). Alveolar soft part sarcoma is found especially in young adults. When diagnosed, it is often metastasised with a poor prognosis. However, when radically resected, long-term survival is possible.
