%X <B>UNASSIGNED: </B>Spontaneous rupture of hepatocellular carcinoma (HCC) is a potentially fatal complication and the third leading cause of death in patients with HCC after tumor progression and liver failure. Previous studies suggested that improved HCC surveillance has decreased the incidence of rupture. This study aims to characterize patients with ruptured HCC over time and identify predictors of rupture.<BR><B>UNASSIGNED: </B>We retrospectively reviewed a prospectively collected database of 1451 HCC patients to identify cases with rupture and predictors of rupture. Data were divided into three 9-year eras to compare and trend patient/tumor characteristics and rupture.<BR><B>UNASSIGNED: </B>Fifty-seven patients (3.9%) presented with spontaneous HCC rupture and the following characteristics: mean age 62.6 years, 73.7% males, 41% cirrhosis, and mean tumor size of 8.0 cm. On multivariate analyses, predictors of rupture included obesity, tumor >5 cm, and single tumors, whereas the presence of cirrhosis was a negative predictor for rupture.Across three eras, there were changes in disease etiology and decreases in tumor size, and more HCCs were found with surveillance. However, more patients were noncirrhotic, and the incidence of spontaneous rupture was unchanged over time.<BR><B>UNASSIGNED: </B>Despite improved early detection of HCC over time, the incidence of rupture has been unchanged. The persistent incidence of rupture may possibly be attributed to increasing proportion of fatty liver-related HCC patients who lack traditional risk factors for surveillance and may not have cirrhosis. Better identification of fatty liver disease and determining which patients need HCC surveillance may be needed in the future to prevent spontaneous rupture.
