Background:
Locoregional colon cancer recurrence occurs in around 10% of patients following initial curative intent primary resection. We hypothesized oncological results can vary based on the recurrence site. Our aim was to determine outcomes for patients undergoing resection with curative intent for locally recurrent colon cancer.
Methods:
Patients with locoregional recurrence after curative intent resection for colon cancer were identified (1999-2017). Demographics, operative details and outcome data were recorded. Kaplan-Meier method was used to compare survival differences.
Results:
Fifty-two patients (mean age, 62) were included. The most common recurrence site was primary anastomosis (48%). R0 resection was obtained in 68%. Major morbidity occurred in 37%. Patients with anastomotic recurrence had a statistically significant overall survival compared to other sites (71.6 vs. 40.8 months respectively with a P value of 0.05).
Conclusions:
Excellent outcomes are possible for curative intent recurrent colon cancer surgery. The site of loco-regional recurrence plays a significant role in outcomes. Table of Contents Summary: Colon cancer recurrence can be treated surgically with optimal outcomes. Anastomotic recurrence is associated with improved survival.
