Abstract

BACKGROUND AND AIMS: Living-donor liver transplantation (LDLT) has been widely performed in patients with end-stage liver disease and hepatocellular carcinoma in Japan. Although extrahepatic cancer survey for LDLT candidates is absolutely required, few reports have indicated the optimal surveillance method for colorectal cancer. The aim of this study is to investigate the feasibility and findings of colonoscopy before LDLT. PATIENTS AND METHODS: From January 2004 to August 2006, we prospectively enrolled all of the scheduled LDLT candidates of our hospital for pretransplant colonoscopy examination. RESULTS: A total of 81 patients were enrolled for colonoscopy. Of these patients, 67 (83%) could actually undergo colonoscopy. Patients who could not undergo colonoscopy exhibited more impaired liver function than those who could (median Model End-Stage Liver Disease score; 25.5 vs. 14.5, P=0.0003). Among patients who underwent colonoscopy, observation of total colon was attained in 64 (96%). Neoplasia was found in 28 (42%) patients, including 4 patients with adenomas ≥10 mm, 1 patient with adenomas with high-grade dysplasia, and 3 patients with invasive cancer. Patients who had advanced neoplasia (adenoma ≥10 mm, adenomas with high-grade dysplasia, or invasive cancer) were likely to have a lower performance status (PS) (7/8 were PS 3) than those who did not (P=0.054). CONCLUSIONS: Clinically significant tumors were found in a considerable portion of LDLT candidates, particularly in lower PS patients. Because immunosuppressive agents after transplantation may worsen malignant tumors, colonoscopy before transplantation is recommended in patients who can tolerate the procedure.
