The role of pelvic exenteration for sarcomatous malignancies.

Pelvic exenteration, although performed most frequently for recurrent squamous cell carcinoma of the cervix and vagina, has been used in selected patients with pelvic sarcoma. Nine patients with various histologic types of sarcoma treated by pelvic exenteration are reported. During this 23-year time period, 46 patients with sarcoma were evaluated for possible exenteration. Patients with embryonal rhadomyosarcoma (sarcoma botryoides) were excluded because these pediatric tumors are now treated with less radical operative procedures, plus radiation and chemotherapy. Six patients had exenteration as primary treatment, and three patients had exenteration as secondary treatment. Four patients developed recurrent disease (mean 5.2 months), and all four died of disease. Five patients were alive at 5 and 10 years, for an absolute survival of 55%. All three patients with mixed mesodermal tumors died of recurrent disease, compared with 83% survival for patients with other sarcoma types. Pelvic exenteration may play a limited but important role in the therapy of pelvic sarcoma.
