PURPOSE : Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) has been established as the standard operative procedure for classic familial adenomatous polyposis( FAP). However, it is unclear which type of surgery should be undertaken for FAP patients with invasive colorectal cancer in clinical practice. This study evaluated the outcome of different surgeries performed in FAP patients with invasive colorectal cancer.
PATIENTS AND METHODS : The study included 21 classic FAP patients with or without invasive colorectal cancer, who underwent proctocolectomy at our institute between 2000 and 2013. Patient background, type of operation, and prognosis were retrospectively examined.
RESULTS : In the non-invasive cancer group, total proctocolectomy with IPAA was performed in 7 patients, and colectomy with ileorectal anastomosis (IRA) was performed in 5 patients. Conversely, in the invasive cancer group, IPAA, proctocolectomy with end ileostomy (TPC), and IRA were performed in 2, 2, and 5 patients, respectively. Overall survival did not differ significantly between the 2 groups( 5 year survival, 88.9% vs 75.0%, p=0.48).
CONCLUSION : These results suggest that IPAA, IRA, or TPC might contribute to survival time prolongation in patients with invasive colorectal cancer, as is the case for those without invasive colorectal cancer.organization:
