Objective: Chances of survival after the diagnosis of recurrent endometrial cancer are poor. Although total pelvic exenteration has been described as a treatment for a select subset of patients with recurrent endometrial cancer, the use of other surgical procedures in this setting has not been well described. The objective of this study was to review our experience with non-exenterative surgery for recurrent endometrial cancer.
Methods: We reviewed the medical records of all patients who underwent non-exenterative surgery for recurrent endometrial cancer between 1/91 and 1/03. Survival was determined from the time of surgery for recurrence to last follow-up. Survival was estimated using Kaplan-Meier methods. Differences in survival were analyzed using the log-rank test. The Fisher's exact test was used to compare optimal versus suboptimal cytoreduction against possible predictive factors.
Results: Twenty-seven patients were identified. Fifteen patients (56%) had disease limited to the retroperitoneum, 10 patients (37%) had intraperitoneal disease, and 2 patients (7%) had both intra- and retroperitoneal disease. Cytoreduction to <or=2 cm of residual disease was achieved in 18 patients (67%), while 9 patients (33%) had cytoreduction to residual disease >2 cm. There were no major perioperative complications or mortalities. The median hospital stay was 7 days (range, 1-18 days). Additional therapies included intraoperative radiation therapy in 9 patients (33%), radiation therapy in 12 patients (44%), and chemotherapy in 10 patients (37%). The median follow-up for the entire cohort was 24 months (range, 5-84 months). The median progression-free survival was 14 months (95% CI, 6-23), and the median disease-specific survival was 35 months (95% CI, 24-not reached). Size of residual disease was the only significant predictor for both progression-free and disease-specific survival. Patients with residual disease <or=2 cm had a median disease-specific survival of 43 months (95% CI, 35-not reached) compared with 10 months (95% CI, 7-29) for those with >2 cm residual (P = 0.01).
Conclusions: Surgical resection for recurrent endometrial cancer may provide an opportunity for long-term survival in a select patient population. The only factor associated with improved long-term outcome was the size of residual disease remaining at the end of surgical resection.
