摘要

The incidence of de novo malignancy (DNM) after liver transplantation (LT) is reported to be 3.1% to 14.4%. It is a known cause of death in long-term recipients. This study aimed to clarify the clinical features and risk factors of DNM. Recipients who underwent adult-to-adult living-donor LT (LDLT) and survived for >6 months were investigated. The medical records were retrospectively reviewed. This study was approved by the institutional review board. In total, 180 patients were included. The indications for LDLT were hepatocellular disease (n = 62), metabolic liver disease (n = 50), cholestatic disease (n = 46), acute liver failure (n = 12), and others (n = 10). The median age at LDLT was 48 (18-71) years, and the follow-up period was 15 (0-29) years. De novo malignancy was diagnosed in 24 recipients (28 sites), including the digestive tract (n = 9), genitourinary (n = 5), gynecologic (n = 5), lung (n = 4), hematological (n = 3), and others (n = 2). The median duration from LDLT to DNM was 7 (0-19) years. Four patients were lost to follow-up due to advanced-stage cancer. R0 (curative treatment) for non-hematological DNM was achieved in 19 lesions (95%). The 10- and 20-year DNM incidence rates were 11% and 20%, respectively. The 20-year survival rates of DNM (59.6%) and non-DNM (59.9%) patients were not significantly different. De novo malignancy was significantly higher in patients with primary sclerosing cholangitis than in others (P < .05). Even in DNM recipients, early detection of malignancy and R0 treatment promises long-term outcomes comparable to those of non-DNM recipients.
