Pelvic exenteration and sphincter preservation in the treatment of soft tissue sarcomas.

摘要

BACKGROUND: Pelvic sarcomas are rare and there are very few effective therapeutic alternatives. A complete resection is considered the main factor associated to a good prognosis, which justifies the employment of a pelvic exenteration (PE) in selected cases. METHODS: Between 1980 and 2000, 96 PE were performed, nine of which were for sarcomas. The clinical characteristics, surgical and anatomopathological aspects and the patients' evolution were described. RESULTS: The median follow-up time was 24 months (ranging from 1 to 57 months). In relation to the sphincters preservation, at least one sphincter was preserved in five patients. There were two post-operative deaths. In the last follow-up, six patients were alive without any evidence of the disease. CONCLUSION: Pelvic exenterations should be performed for the treatment of selected cases of locally advanced pelvic sarcomas. Sphincter preservation may be performed, provided that oncological resection principles are obeyed.
