Background:
Locally recurrent rectal cancer involving the upper sacrum is generally considered a contra-indication to curative surgery. The aim of this study was to determine if a survival benefit was seen in patients undergoing high sacrectomy.
Methods:
All patients with locally recurrent rectal cancer involving the sacrum above the 3rd sacral body between 1999 and 2007 were retrospectively reviewed. Kaplan-Meier survival analysis was performed.
Results:
Nine patients were identified with a median age of 63 years. The proximal extent of sacral resection was through S2 (n = 6), S1 (n = 2), and L5-S1 (n = 1). All patients had R0 negative-margin resection. Median operative time was 13.7 hr, and median operative blood transfusion was 3.7 L. Thirty-day mortality was nil. Postoperative complications requiring surgical intervention occurred in three patients. Local re-recurrence in the pelvis occurred in one patient. The overall median survival was 31 months (range, 2-39 months). Three patients still alive are free of disease after 40, 76, and 101 months, respectively. Ultimately, all deaths were due to metastatic disease.
Conclusions:
High sacrectomy that achieves clear margins in patients with recurrent rectal cancer is safe and feasible. A majority will die of metastatic disease, but long-term survival may be possible in some patients.
