Resection of Isolated Pelvic Recurrences after Colorectal Surgery: Long-Term Results and Predictors of Improved Clinical Outcome

Recurrence in the pelvis after resection of a rectal or rectosigmoid cancer presents a dilemma. Resection offers the only reasonable probability for cure, but at the cost of perioperative morbidity and potential mortality. Clinical decision making remains difficult.
Patients resected with curative intent for isolated pelvic recurrences after curative colorectal surgery from 1988 through 2003 were reviewed retrospectively. Clinical and pathologic factors, salvage operations, and complications were recorded. The primary measured outcome was overall survival. Univariate and multivariate analyses were conducted to identify prognostic factors of improved outcome.
Ninety patients underwent an attempt at curative resection of a pelvic recurrence with median follow-up of 31 months. Complications occurred in 53% of patients. Operative mortality was 4.4% (4 of 90). Median overall survival was 38 months, and estimated 5-year survival was 40%. A total of 51 of 86 patients had known recurrences (15 local, 16 distant, 20 both). Multivariate analysis revealed that preoperative carcinoembryonic antigen level and final margin status were statistically significant predictors of outcome.
The resection of pelvic recurrences after colorectal surgery for cancer can be performed with low mortality and good long-term outcome; however, morbidity from such procedures is high. Low preoperative carcinoembryonic antigen and negative margin of resection predict improved survival.
