Background & AimsHepatocellular carcinoma (HCC) is the second most common cause of cancer deaths worldwide. The global HCC BRIDGE study was a multiregional, large-scale, longitudinal cohort study undertaken to improve understanding of real-life management of patients with HCC, from diagnosis to death.MethodsData were collected retrospectively from January 2005 to September 2012 by chart reviews of eligible patients newly diagnosed with HCC at participating institutions.ResultsForty-two sites in 14 countries contributed final data for 18 031 patients. Asia accounted for 67% of patients, Europe for 20% and North America for 13%. As expected, the most common risk factor was hepatitis C virus in North America, Europe and Japan, and hepatitis B virus in China, South Korea and Taiwan. The most common Barcelona Clinic Liver Cancer stage at diagnosis was C in North America, Europe, China and South Korea, and A in Taiwan and Japan. Across all stages, first HCC treatment was most frequently transarterial chemoembolization in North America, Europe, China and South Korea, percutaneous ethanol injection or radiofrequency ablation in Japan and resection in Taiwan. Survival from first HCC treatment varied significantly by region, with median overall survival not reached for Taiwan and 60, 33, 31, 24 and 23 months for Japan, North America, South Korea, Europe and China respectively (P < 0.0001).ConclusionsInitial results from the BRIDGE study confirm previously reported regional trends in patient demographic characteristics and HCC risk factors, document the heterogeneity of treatment approaches across regions/countries and underscore the need for earlier HCC diagnosis worldwide.

Progression of hepatitis B in patients with lamivudine-resistant strains is slowed down by adefovir dipivoxil (ADV). Whether the time point of ADV administration (genotypic vs. phenotypic resistance) influences the outcome of therapy is unknown. We compared the outcome of ADV therapy in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B patients with genotypic and phenotypic resistance to lamivudine. Ten milligrams of ADV was administered daily for 2 years to 46 HBeAg-negative patients at the time of phenotypic resistance (group A, >6 log 10 copies/mL of hepatitis B virus [HBV] DNA and high alanine aminotransferase [ALT] levels) and 28 patients at the time of genotypic resistance (group B, 3-6 log 10 copies/mL of HBV-DNA and normal ALT). HBV DNA was assessed every 2 months using Versant 3.0 assay, and lamivudine resistance was confirmed via INNO-LiPA assay in all patients. By month 3, HBV DNA tested negative in all patients from group B compared with only 20 (46%) in group A (P < .0001). The 2-year rates of virological response were 100% in the former patients and 78% in the latter ones (P < .0001). ALT levels remained persistently normal in all group B patients, whereas in group A patients they normalized at rates of 50% at month 6 (P < .0001), 72% at month 12 (P < .01), and 93% at month 24. None of the patients developed ADV resistance or ADV-related side effects. In conclusion, to optimize antiviral treatment in HBeAg-negative patients selecting resistant strains to lamivudine, ADV should be added to lamivudine as soon as genotypic resistance is detected.
