BackgroundA multimodality approach to patients with locally recurrent rectal cancer that includes surgery is associated with a significant survival advantage when tumor-free margins are achieved. Patients with advanced tumors will require extended sacropelvic resection to optimize oncologic outcomes.ObjectiveThe aim of this study was to assess the safety, feasibility, and oncologic outcomes of extended sacropelvic resection for locally recurrent rectal cancer at our institution.DesignA retrospective review identified 406 patients who had surgery for locally recurrent rectal cancer between 1997 and 2007. From this group, all patients who underwent a curative-intent sacropelvic resection were analyzed.SettingsThis investigation was conducted at an academic tertiary referral center.PatientsThirty patients (24 male) were identified. Median age was 59 years (range, 25-84). Operations were performed for a first local recurrence (n = 24), a second recurrence (n = 5) and for a third recurrence (n = 1).InterventionsTwenty-six patients underwent neoadjuvant radiation, and 20 received intraoperative radiation therapy. All patients underwent extended sacropelvic resection.Main Outcome MeasuresThe primary outcomes measured were early (<30 days) and late (>30 days) surgical complications. Overall and disease-free survivals were estimated by using the Kaplan-Meier technique.ResultsMargin-negative resection was achieved in 93%. The most proximal level of spinal transection was the fourth lumbar space, and 4 patients underwent lower extremity amputation. There was no mortality, and early morbidity was seen in 76%. Median follow-up was 2.7 years (range, 2 months to 10.8 years). Overall survival at 2 and 5 years was 86% and 46%. Disease-free survival at 2 and 5 years was 79% and 43%.LimitationsThis study was limited by its retrospective nature and the limited number of patients.ConclusionsWe found extended sacropelvic resection for locally recurrent rectal cancer to be feasible and safe with overall and disease-free survival rates in comparison with survival rates seen in patients undergoing nonsacropelvic resections for locally recurrent rectal cancer.
