    Background Limited data exist on the burden and features of non‐cirrhotic hepatocellular carcinoma (HCC) in the United States. Aim To evaluate characteristics, aetiologies, trends and outcomes of non‐cirrhotic HCC from 2000 to 2014 at five large US centres Methods Patient, tumour and liver disease aetiology data were collected. The presence of underlying cirrhosis was assessed based on published criteria. Results Of 5144 eligible patients with HCC, 11.7% had no underlying cirrhosis. Non‐cirrhotic patients were older (64.1 vs 61.2 years), more frequently females (33.9% vs 20.8%) and less frequently black (8.3% vs 12.4%) (P < .001 for all). Among non‐cirrhotic patients, non‐alcoholic fatty liver disease (NAFLD) was the most common liver disease (26.3%), followed by hepatitis C virus (HCV) (12.1%) and hepatitis B virus (HBV) (10%) infections. As of 2014, there was increased percentage of cirrhotic HCC and a decline in non‐cirrhotic HCC mainly due to significant annual increases in cirrhotic HCC due to HCV (0.96% [P < .0001]) and NAFLD (0.66% [P = .003]). Patients with non‐cirrhotic HCC had larger tumours (8.9 vs 5.3 cm), were less frequently within Milan criteria (15% vs 39%), more frequently underwent resection (43.6% vs 8%) (P < .001 for all) and had better overall survival than cirrhotic HCC patients (median 1.8 vs 1.3 years, P = .004). Conclusions Nearly 12% of HCCs occurred in patients without underlying cirrhosis. NAFLD was the most common liver disease in these patients. During the study, the frequency of non‐cirrhotic HCC decreased, whereas that of cirrhotic HCC increased. Although non‐cirrhotic patients presented with more advanced HCC, their survival was better.

    Distinctive Features and Outcomes of Hepatocellular Carcinoma in Patients With Alcohol-Related Liver Disease: A US Multicenter Study
    (Wolters Kluwer Health, 2020-03) deLemos, Andrew; Patel, Milin; Gawrieh, Samer; Burney, Heather; Dakhoul, Lara; Miller, Ethan; Scanga, Andrew; Kettler, Carla; Liu, Hao; Roche, Patrick; Wattacheril, Julia; Chalasani, Naga; Medicine, School of Medicine
    Introduction: The burden of hepatocellular carcinoma (HCC) occurring in patients with alcoholic liver disease (ALD) is increasing at an alarming rate. The aims of this study were to compare the patient and tumor characteristics of HCC occurring in ALD-alone relative to and in addition to other chronic liver diseases. Methods: Patients diagnosed with HCC between 2000 and 2014 were identified at 5 US clinical centers. The patients were categorized as ALD-alone, ALD plus viral hepatitis, or a non-ALD etiology. Clinical and tumor characteristics among the 3 groups were compared, and survival probability was estimated by the Kaplan-Meier method. The frequency of noncirrhotic HCC was compared across the 3 groups. Results: A total of 5,327 patients with HCC were analyzed. Six hundred seventy (12.6%) developed HCC due to underlying ALD. Ninety-one percent of ALD-related HCC arose in men, in contrast to non-ALD etiologies where men accounted for 70% of HCCs cases (P < 0.001). Patients with ALD-alone-related HCC were older at diagnosis and had tumors less likely to be detected as part of routine surveillance. The ALD-alone cohort was least likely to be within the Milan criteria and to undergo liver transplantation. Overall survival in the ALD-alone HCC cohort was lower than the other 2 groups (1.07 vs 1.31 vs 1.41 years, P < 0.001). HCC in the noncirrhotic ALD cohorts occurred in only 3.5% of the patients compared with 15.7% in patients with non-ALD etiologies (P < 0.001). Discussion: HCC occurring in patients with ALD occurred mostly in older men and almost exclusively in a cirrhotic background. They present with advanced tumors, and their survival is lower than HCCs occurring in non-ALD.

    Risk factors for hepatocellular carcinoma in cirrhosis due to nonalcoholic fatty liver disease: A multicenter, case-control study
    (Baishideng Publishing Group, 2017-03-08) Corey, Kathleen E.; Gawrieh, Samer; deLemos, Andrew S.; Zheng, Hui; Scanga, Andrew E.; Haglund, Jennifer W.; Sanchez, Jorge; Danford, Christopher J.; Comerford, Megan; Bossi, Krista; Munir, Samina; Chalasani, Naga; Wattacheril, Julia; Department of Medicine, IU School of Medicine
    AIM To identify risk factors associated with hepatocellular carcinoma (HCC), describe tumor characteristics and treatments pursed for a cohort of individuals with nonalcoholic steatohepatitis (NASH) cirrhosis. METHODS We conducted a retrospective case-control study of a well-characterized cohort of patients among five liver transplant centers with NASH cirrhosis with (cases) and without HCC (controls). RESULTS Ninety-four cases and 150 controls were included. Cases were significantly more likely to be male than controls (67% vs 45%, P < 0.001) and of older age (61.9 years vs 58 years, P = 0.002). In addition, cases were more likely to have had complications of end stage liver disease (83% vs 71%, P = 0.032). On multivariate analysis, the strongest association with the presence of HCC were male gender (OR 4.3, 95%CI: 1.83-10.3, P = 0.001) and age (OR = 1.082, 95%CI: 1.03-1.13, P = 0.001). Hispanic ethnicity was associated with a decreased prevalence of HCC (OR = 0.3, 95%CI: 0.09-0.994, P = 0.048). HCC was predominantly in the form of a single lesion with regional lymph node(s) and distant metastasis in only 2.6% and 6.3%, respectively. Fifty-nine point three percent of individuals with HCC underwent locoregional therapy and 61.5% underwent liver transplantation for HCC. CONCLUSION Male gender, increased age and non-Hispanic ethnicity are associated with HCC in NASH cirrhosis. NASH cirrhosis associated HCC in this cohort was characterized by early stage disease at diagnosis and treatment with locoregional therapy and transplant.
