Little is known about the natural course of nonalcoholic fatty liver disease (NAFLD) with advanced fibrosis. We describe long-term outcomes and evaluate the effects of clinical and histologic parameters on disease progression in patients with advanced NAFLD.We conducted a multi-national study of 458 patients with biopsy-confirmed NAFLD with bridging fibrosis (F3, n = 159) or compensated cirrhosis (222 patients with Child-Turcotte-Pugh scores of A5 and 77 patients with scores of A6), evaluated from April 1995 through November 2013 and followed until December 2016, death, or liver transplantation at hepatology centers in Spain, Australia, Hong Kong, and Cuba. Biopsies were re-evaluated and scored; demographic, clinical, laboratory, and pathology data for each patient were collected from the time of liver biopsy collection. Cox proportional and competing risk models were used to estimate rates of transplantation-free survival and major clinical events and to identify factors associated with outcomes.During a mean follow-up time of 5.5 years (range, 2.7-8.2 years), 37 patients died, 37 received liver transplants, 88 had initial hepatic decompensation events, 41 developed hepatocellular carcinoma, 14 had vascular events, and 30 developed nonhepatic cancers. A higher proportion of patients with F3 fibrosis survived transplantation-free for 10 years (94%; 95% confidence interval [CI], 86%-99%) than of patients with cirrhosis and Child-Turcotte-Pugh A5 (74%; 95% CI, 61%-89%) or Child-Turcotte-Pugh A6 (17%; 95% CI, 6%-29%). Patients with cirrhosis were more likely than patients with F3 fibrosis to have hepatic decompensation (44%; 95% CI, 32%-60% vs 6%, 95% CI, 2%-13%) or hepatocellular carcinoma (17%; 95% CI, 8%-31% vs 2.3%, 95% CI, 1%-12%). The cumulative incidence of vascular events was higher in patients with F3 fibrosis (7%; 95% CI, 3%-18%) than cirrhosis (2%; 95% CI, 0%-6%). The cumulative incidence of nonhepatic malignancies was higher in patients with F3 fibrosis (14%; 95% CI, 7%-23%) than cirrhosis (6%; 95% CI, 2%-15%). Death or transplantation, decompensation, and hepatocellular carcinoma were independently associated with baseline cirrhosis and mild (33%) steatosis, whereas moderate alcohol consumption was associated with these outcomes only in patients with cirrhosis.Patients with NAFLD cirrhosis have predominantly liver-related events, whereas those with bridging fibrosis have predominantly nonhepatic cancers and vascular events.
