Tumor factors associated with clinical outcomes in patients with hepatitis B virus infection and hepatocellular carcinoma Tong MJ; Siripongsakun S; Stanford-Moore G; Hsu L; Chang PW; Blatt LMGastroenterol Hepatol (N Y) 2012[Dec]; 8 (12): 808-19BACKGROUND AND AIMS: Hepatitis B virus (HBV) infection is a common cause of hepatocellular carcinoma (HCC) in the United States. This study evaluated the impact of surveillance and treatment on HBV-infected HCC patients and identified factors associated with survival. METHODS: From 1981 to 2010, 166 hepatitis B surface antigen (HBsAg)-positive HCC patients were evaluated. Fifty-eight patients had HCC detected by surveillance, while 108 patients presented with HCC. RESULTS: Compared to patients detected by surveillance, those presenting with HCC had more symptoms (65.7% vs 41.4%; P=.002), were more frequently outside of Milan criteria (73.7% vs 29.6%; P<.001), more often presented with diffuse tumors (23.2% vs 1.9%; P<.001), and had a shortened median survival time (9.5 months vs 18.7 months; P=.003). Patients who presented with diffuse tumors were younger and more often male (P=.002-.007), had a higher alpha-fetoprotein (AFP) level (P=.023), and had a median survival time of only 1.68 months. By multivariate analysis, factors that were significantly associated with mortality included diffuse tumors (hazard ratio [HR], 6.30; 95% confidence interval [CI], 3.14-12.66; P<.001), being outside of Milan criteria (HR, 2.02; 95% CI, 1.26-3.23; P=.005), albumin level (HR per 1 standard deviation decrease, 1.4; 95% CI, 1.15-1.72; P=.001), AFP level (HR per 1 log standard deviation increase, 1.38; 95% CI, 1.13-1.67; P=.001), and receiving liver transplantation versus other treatments (HR, 0.08-0.38; 95% CI, 0.03-0.87; P<.001 to P=.022). CONCLUSION: In the United States, HBV-related HCC is a common malignancy, especially among Asian immigrants. Identification of HBsAgpositive subjects and routine HCC surveillance are essential for improving survival in these patients.ä |
