The optimal strategy for adjuvant therapy after curative resection for hepatocellular carcinoma (HCC) patients with solitary tumor and microvascular invasion (MVI) is controversial. This trial evaluated the efficacy and safety of adjuvant transcatheter arterial chemoembolization (TACE) after hepatectomy versus hepatectomy

Several anti-viral drugs are approved for the treatment of hepatitis B virus (HBV) infection. However, whether quantitative hepatitis B surface antigen (qHBsAg) can predict the therapeutic response during long-term entecavir treatment remains unclear. Fifty-five chronic hepatitis B (CHB) patients who
