Background: The benefits in terms of curative resection and survival of pelvic exenterations for specific extraluminal pelvic recurrences from rectal cancer in the era of total mesorectal excision were assessed.
Methods: We conducted a single-center review of patients with extraluminal pelvic recurrence from colorectal cancer between March 2004 and November 2010. Twenty-seven pelvic exenterations (13 posterior and 14 total) were performed. Independent predicative factors such as age, sex, local control on first surgery, pelvic sidewall excision, initial International Union Against Cancer (UICC) staging, sphincter-preserving resection at first surgery, tumor presentation on computed tomography and magnetic resonance imaging (pelvis sidewall involvement, number of fixation sites, ureteral involvement), local disease-free interval, previous symptoms, and postoperative treatment were analyzed.
Results: No operative mortality was noted in this series. Overall morbidity rate was 74%; 22% of the patients developed severe complications. Complete surgical clearance (R0) was obtained in 63% of the patients. The rate of R0 resections was lower in total pelvic exenteration (57%) than in posterior pelvic exenteration (69%). Three years overall survival and disease-free survival were 76% and 59%, respectively. Curative resection (R0) was the only independent prognostic factor for overall survival (P = .0016) and disease-free survival (P < .0001).
Conclusion: Pelvic exenterations for extraluminal pelvic recurrences from rectal cancer afford a high R0 resection rate with acceptable morbidity.
