Lee, Eun Sik; Lee, Chong Wook

Abstract

Pelvic sarcoma is rare disease. It is very difficult to detect and to treat such tumor in early stage due to the location. But modern anti-cancer therapeutic modalities improve the prognosis. Herein we analyze the experiences of 8 patients of pelvic sarcoma during a recent 10 year period. Six patients were male and 2 were female. Presentations were urinary obstruction in 3 patients, abdominal mass in 5. Various radiologic diagnostic examinations were performed and the results of compressing the adjacent organs rather invasion were founded. Distant metastasis was not recognized in all cases. Exploratory laparotomies were performed in all patients. In 5 patients, mass excision with or without adjacent organs was possible and fecal or urinary diversions were done. In 3 patients, the excision was impossible and fecal, urinary diversions and biopsy for pathologic diagnosis were done. Rhabdomyosarcoma was in one patient, leiomyosarcoma in 3, liposarcoma in 3 and extraskeletal myxoid chondrosarcoma is one. In postoperative long term follow up, the 3 patients died within 6 months whose tumors were not resectable. The 3 patients survived more than 3 years whose tumor masses were excised and who received adjuvant chemotherapy and/or radiotherapy. In one patient, a local recurrence occurred and died of sepsis during postoprative chemotherapy, in one patient now in observation under radiotherapy. The treatment of sarcoma in pelvic cavity must include multiple anti-cancer therapeutic modalities.
