Purpose: The purpose of this study was to investigate the oncological and clinical outcome of ulcerative colitis (UC) patients with coexisting colorectal cancer/dysplasia following stapled ileal pouch-anal anastomosis (IPAA). Materials and methods: One hundred eighty-five UC patients who underwent stapled IPAA were followed prospectively in a comprehensive pouch clinic. They were divided into three groups: colorectal cancer, dysplasia, and no cancer/dysplasia. Demographic parameters, clinical data, and oncological and functional outcome of the three groups were compared. Results: Sixteen patients had cancer and 14 had dysplasia. Two of the three cancer patients who developed metastatic disease died. One patient who had rectal cancer was found to have cancer cells in the rectal cuff 10years after IPAA. All other cancer/dysplasia patients were disease-free at 62months (median). The 5-year survival rate was 87.5% for the cancer group and 100% for the others (p < 0.0001). Chemotherapy (nine patients) did not affect pouch function. Two rectal cancer patients who received radiotherapy did not maintain a functioning pouch. Overall pouch failure rates were 19%, 7%, and 6% for cancer, dysplasia, and no-cancer/dysplasia patients, respectively (p = 0.13). The mean frequency of bowel movements in 24h was similar between the groups. Conclusions: Stapled IPAA is a reasonable option for UC patients with cancer/dysplasia. Chemotherapy is safe, but the effect of radiation on pouch outcome is worrisome. Close long-term follow-up for UC patients with cancer/dysplasia is recommended for early detection of possible recurrence.
