The role of exenterative surgery and urinary diversion in persistent or locally recurrent gynecological malignancy: complications and survival.

ABSTRACT

OBJECTIVE: Treatment options in patients with persistent or locally recurrent cervical cancer are limited. The aim of this study was to determine the chance of cure and associated morbidity following pelvic exenteration. PATIENTS AND METHODS: Consecutive patients who underwent pelvic exenteration between January 1992 and December 2006 at the University Hospital of Bern or the Karlsruhe Medical Center were evaluated. Time to recurrence, type of exenteration and urinary diversion, pathological stage, postoperative complications and survival were assessed. RESULTS: Initial therapy prior to diagnosis of persistent or locally recurrent disease included radiation therapy in 51%. Anterior exenteration was performed in 37 (86%) and total exenteration in 6 (14%). Half of the women underwent additional procedures. A continent urinary diversion was constructed in 16 and an ileal conduit in 27 patients. Early postoperative complications were generally minor and only 2 patients required surgical intervention. Four intestinal fistulas were successfully treated conservatively. Late complications were mainly tumor-related. Complication rates associated with the urinary diversion were low and there was no difference in complications between continent and incontinent diversions. The overall disease-specific 5-year survival rate after exenteration was 36.5%. Survival correlated significantly with surgical margin status. CONCLUSION: In patients with persistent or locally recurrent gynecological malignancy of the pelvis, exenteration is a viable option with long-term survival in over one third of patients. Continent urinary diversion did not show higher complication rates than an ileal conduit and should be considered even in irradiated patients. This may be of greater significance in younger patients in whom an intact body image can play an important role in quality of life.
