To determine the value of early alterations of the tumor markers α-fetoprotein (AFP) and des-γ-carboxy prothrombin (DCP) for predicting the outcomes of patients with advanced hepatocellular carcinoma (HCC) who receive sorafenib.Tumor response, overall survival (OS), and progression-free survival (PFS) were retrospectively analyzed in 59 patients with advanced HCC. Serum AFP and DCP were examined for early elevation within 4 weeks after the initiation of sorafenib. An increase in AFP was defined as AFP of more than 20%, and an increase in DCP was defined as more than two-fold higher level than the baseline. The relationship of the clinical characteristics, laboratory data at baseline, and early elevations of AFP and DCP with disease progression was analyzed.The median OS and PFS were 11 and 3.3 months, respectively. The rate of progressive disease (PD) was 54%, and an early increase in AFP was significantly related to PD (P=0.006) and was a significant independent predictor of both poorer OS and PFS (P0.001, hazard ratio, 4.14; 95% confidence interval, 1.946-8.811; and P=0.001, hazard ratio, 2.852; 95% confidence interval, 1.524-5.337, respectively). There was no association between early increase in DCP and clinical outcomes.Early increase in AFP predicted PD and poorer survival and may thus be a useful biomarker in patients with advanced HCC who receive sorafenib.

Inhibitors of 3-hydroxy,3-methylglutaryl coenzyme A (HMG-CoA) reductase have been reported to decrease the cholesterol saturation index (CSI) in duodenal bile in humans and to prevent formation of cholesterol gallstones in animal studies. We performed a prospective study to evaluate the role of HMG-CoA reductase inhibitors as gallstone-dissolving agents. Fifty patients with radiolucent gallstones in a gallbladder opacifying at drip infusion cholecystography were treated with either 10 mg/day simvastatin plus 600 mg/day ursodeoxycholic acid (group 1, n=26) or 600 mg/day ursodeoxycholic acid alone (group 2, n=24) for 12 months. The ratio of solitary to multiple gallstone cases was 21:29. Plasma lipid levels were assessed and ultrasonographic examination of the gallbladder was performed at baseline and at 3-month intervals during treatment. Duodenal bile sampling was performed in five patients in each group at baseline and after 12 months of treatment. Plasma cholesterol decreased significantly in group 1 but not in group 2. In solitary gallstone cases, no significant difference in dissolution rates was observed between groups 1 (3 of 9, 33%) and 2 (4 of 12, 33%). In contrast, the dissolution rate in multiple gallstone cases was significantly higher in group 1 (12 of 17, 71%) than in group 2 (3 of 12, 25%) (p0.01). Bile cholesterol saturation index was significantly decreased (p0.01) but did not significantly differ between the two groups. These results suggest that combination therapy with simvastatin and ursodeoxycholic acid is more effective for cholesterol gallstone dissolution than ursodeoxycholic acid monotherapy in patients with multiple gallstones.
