Objective:
To update our report on the outcome of patients who underwent extended pelvic resection (EPR) for recurrent or persistent uterine and cervical malignancies.
Methods:
We reviewed the records of all patients who underwent EPR between 6/2000 and 07/2011. EPR was defined as an en-bloc resection of a pelvic tumor with sidewall muscle, bone, major nerve, and/or major vascular structure. Complications up to 180 days post surgery were analyzed. Survivals were estimated using the Kaplan-Meier method.
Results:
We identified 22 patients. Median age at the time of EPR was 58 years (range, 36-74). Median tumor diameter was 5.4 cm (range, 1.5-11.2). Primary tumor sites included: uterus, 13; cervix, 7; synchronous uterus/cervix, 1; and synchronous uterus/ovary, 1. The EPR structures were: muscle, 13; nerve, 10; bone, 8; vessel, 5. Complete gross resection with microscopically negative margins (R0 resection) was achieved in 17 patients (77%). There were no perioperative mortalities. Major postoperative complications occurred in 14 patients (64%). The two most common morbidities were pelvic abscesses and peripheral neuropathies. Median follow-up time was 28 months (range, 6-99). The 5-year overall survival (OS) for the entire cohort was 34% (95% CI, 13-57). For the 17 patients who had an R0 resection, the 5-year OS was 48% (95% CI, 19-73). In patients with positive pathologic margins (n=5), the 5-year OS was 0%.
Conclusion:
EPR was associated with prolonged survival when an R0 resection was achieved. The high rate of postoperative complications remains a hallmark of these procedures and properly selected patients should be extensively counseled preoperatively.
