Ye JZ, et al. - The efficacy and safety of postoperative adjuvant transcatheter arterial chemoembolization (PA-TACE) were investigated in preventing tumor recurrence and improving survival in Barcelona Clinic Liver Cancer (BCLC) early (A) and intermediate (B) stage hepatocellular carcinoma (HCC) patients with microvascular invasion (MVI). PA-TACE was a safe adjuvant intervention. It could efficiently prevent tumor recurrence and improve the survival of BCLC early- and intermediate-stage HCC patients with MVI.
