| Outline of Final Research Achievements |
The aim of this study was to clarify the specific miRNAs in serum that could predict the early response of HCC to sorafenib treatment.Analyzing the sera from screening cohort, we selected five miRNAs. Through further analysis using a validation cohort and healthy control subjects, we found that miR-181a-5p and miR-339-5p showed significant differences in serum levels among patients with partial response (PR), stable disease (SD), and progressive disease (PD). We also analyzed the factors associated with disease control (DC); patients with DC showed a significantly higher level of serum miR-181a-5p than non-DC patients or healthy control subjects. We further conducted multivariate analysis among HCC patients with Barcelona Clinic Liver Cancer stage C using extrahepatic metastasis, serum decarboxiprothrombin and miR-181a-5p levels as covariables; serum miR-181a-5p was the only independent factor for achieving DC and affecting overall survival.
