Background:
The present study investigated outcomes following surgical resection of hepatocellular carcinoma (HCC) in nonalcoholic fatty liver disease (NAFLD).
Methods:
Patients (n = 225) undergoing resection for HCC were divided into three groups: hepatitis C viral group (n = 147), hepatitis B viral group (n = 61), and NAFLD group (n = 17). Clinicopathological characteristics and surgical outcomes were analyzed retrospectively.
Results:
Patients in the NAFLD group were older (P < 0.001), with a higher body mass index (P < 0.001) and larger tumors (P = 0.002) than patients who were positive for hepatitis viral markers. Eight patients in the NAFLD group were found to have nonalcoholic steatohepatitis (NASH) histologically. Postoperative morbidity and 30-day mortality rates were significantly higher in the NAFLD group (59% and 12%, respectively) than in the hepatitis C viral (31% and 0.7%, respectively) and hepatitis B viral (28% and 3.3%; P = 0.043 and P = 0.016, respectively) groups. All deaths in the NAFLD group were in patients with NASH-related cirrhosis who had undergone right hemihepatectomy. Survival after resection was comparable among the three groups (P = 0.391), but patients with NAFLD showed better disease-free survival on univariate (P = 0.048) and multivariate (P = 0.020) analyses.
Conclusions:
Surgical resection may provide a survival benefit for patients with NAFLD-related HCC. Patients with NASH-related cirrhosis undergoing major hepatic resection should be treated carefully.
