Objective To analyze the incidence and risk factors of colorectal adenomatous polyps (CAP) in recipients after liver transplantation. Methods Seventy-seven liver transplant recipients and 231 individuals undergoing colonoscopy during physical examination were recruited in this study. The incidence of CAP and pathological examination results were analyzed. Clinical data of liver transplant recipients were collected. According to the incidence of CAP, liver transplant recipients were divided into the CAP group (n=28) and non-CAP group (n=49). The risk factors of CAP after liver transplantation were identified. Results The 5-year cumulative incidence rates of colorectal polyps in liver transplant recipients and physical examination individuals were 43% and 34%, and 29% and 23% for the 5-year cumulative incidence rates of CAP, with no significant differences (both P > 0.05). Among all liver transplant recipients, 65 polyps were detected. The quantity of polyps in 1 case was excessively high and not counted. Multiple polyps were identified in certain recipients. Five polyps were not prepared for pathological examination due to small size. Pathological examination of 60 polyps demonstrated 25 inflammatory polyps, 33 CAP (8 complicated with low-grade intraepithelial neoplasia and 3 complicated with high-grade intraepithelial neoplasia), and 2 well-differentiated adenocarcinoma. Cox model analysis prompted that use of ciclosporine after liver transplantation was an independent risk factor for CAP in the recipients. Conclusions The risk of CAP is slightly elevated after liver transplantation. Postoperative use of ciclosporine is an independent risk factor for CAP in recipients after liver transplantation. Colonoscopy should be emphasized in the recipients after liver transplantation.

Objective To investigate the incidence of de novo malignant tumors of the digestive system after liver transplantation (LT) in China. Methods Relevant literature review was performed from Wanfang data, China National Knowledge Infrastructure (CNKI) and Chongqing VIP. The retrieval time started from the establishment of each database to May 9, 2019. The Chinese search terms were liver transplantation+ postoperative/de novo+ malignant tumor/cancer. The age distribution, sex composition, time of diagnosis, involved organs, treatment and clinical prognosis of recipients with de novo malignant tumors of the digestive system after LT in China were retrospectively analyzed. Results After literature screening, 16 articles were eventually selected including 47 cases of de novo malignant tumors of the digestive system after LT. A majority of them were male recipients. The age of the recipients was 51 (23-65) years old, most of them were middle age (45-59 years old). The average time of diagnosis of de novo malignant tumors of the digestive system after operation was 43 (2-156) months, with the highest number of cases within postoperative 1-3 years. Colon and stomach were the most common tumor sites. Surgery combined with radiotherapy and chemotherapy remained the main treatment option. However, the overall clinical prognosis of patients with de novo malignant tumors of the digestive system after LT was poor with a mortality rate of 51%. Conclusions In China, colon cancer and gastric cancer are the main de novo malignant tumors of the digestive system after LT. The overall clinical prognosis of patients with de novo malignant tumors of the digestive system is poor. Sufficient attention should be paid to postoperative monitoring and prevention.
