ABSTRACT
BACKGROUND AND AIMS: The incidence of intrahepatic cholangiocarcinoma (ICC) in non-alcoholic fatty liver disease (NAFLD) is increasing gradually. The prognosis of NAFLD-ICC has not been well studied. We aim to investigate the prognosis of patients with NAFLD-ICC after curative-intent partial hepatectomy (PH).
METHODS: Multi-center data from January 2003 to January 2014 were retrospectively analyzed. The prognosis of ICC was analyzed using PSM and compared with hepatitis B virus (HBV)-related ICC.
RESULTS: A total of 898 patients with ICC were included in this study. Of them, 199 (22.2%) were NAFLD-ICC, and 699 (77.8%) were HBV-ICC. Multivariate analysis showed that CA19-9 ≥ 37 U/mL, microvascular invasion, tumor size > 5 cm, multiple tumors, and lymph node (LN) metastasis were independent risk factors for early recurrence (ER) in ICC patients. After a 1:1 PSM, NAFLD-ICC has worse 5-year overall survival (OS) (24.0% vs. 48.9%), 5-year recurrence (80.9% vs. 55.0%), and ER (58.5% vs. 30.0%) than that of HBV-ICC (all P < 0.01). Multivariable analysis showed NAFLD was an independent risk factor for OS (hazard ratio [HR] 2.26, 95% CI 1.63-3.13, P < 0.001), tumor recurrence (HR 2.24, 95%CI 1.61-3.10, P < 0.001) and ER (HR 2.23, 95%CI 1.60-3.09, P < 0.001) in patients with ICC after PH. The sensitivity analysis indicated that NAFLD-ICC patients were more likely to experience ER.
CONCLUSION: Compared with HBV-ICC, NAFLD-ICC has a worse prognosis and was more likely to relapse early. More frequent surveillance should be considered.
