Hemipelvectomy: a changing perspective for a rare procedure.
OBJECTIVE
To compare the prognosis of patients undergoing a hemipelvectomy (HP) in the treatment of pelvic sarcomas and carcinomas and to review the morbidity and mortality associated with HP.


METHODS
Retrospective chart review.


METHODS
The Foothills Hospital, University of Calgary, Calgary, Alberta.


METHODS
Thirteen patients with clinically and radiographically isolated malignancies involving the bony pelvis and adjacent structures.


METHODS
Patients were treated with either an external HP (9 patients) or internal HP (4) in 1983-2001.


METHODS
Survival and recurrence rates for patients in 2 histopathologic groups (sarcoma v. carcinoma); morbidity and mortality associated with HP.


RESULTS
Hemipelvectomy was performed for 7 sarcomas (4 primary bone and 3 soft tissue) and 6 carcinomas (5 genital tract and 1 unknown primary). Seven of the 9 external HPs involved composite resection of other pelvic structures, including other pelvic viscera (3 patients), sacrum (3) and portions of lumbar vertebrae and nerves (1). There were no additional resections among the 4 internal HPs, but 3 patients had allograft reconstruction. Length of stay averaged 30 days (range 14-70 d). At least 1 complication occurred in 10 of 13 cases. The most common complication was flap necrosis occurring in 5 patients (38%). There was 1 perioperative death (8%). The survival of patients treated for sarcomas was better than for carcinomas, which were primarily of the genital tract. Only 1 of the patients with a pelvic sarcoma died of disease (86% disease-specific survival), with a median follow-up of 12 months (range 9-108 mo). Of the 7 sarcoma patients 5 were disease-free at last follow-up. One of 6 pelvic carcinoma patients died perioperatively, with another dying of unknown causes 4 months after surgery. Of the 4 remaining patients 3 died of disease, resulting in a median survival of 9 months (range 4-20 mo). Four of 6 patients with pelvic carcinomas developed recurrent disease, none local.


CONCLUSIONS
HP has considerable morbidity but is a viable and potentially curative treatment for patients with pelvic sarcomas. With pelvic carcinomas HP was not curative, but did provide short-term local disease control. Future improvements in imaging techniques and quality-of-life studies may help with patient selection. The role of HP in recurrent carcinoma remains to be determined.
