Efficacy of postoperative adjuvant transcatheter arterial chemoembolization in hepatocellular carcinoma patients with microvascular invasion

Figure 1 Overall survival and recurrence-free survival curves of hepatocellular carcinoma patients who either underwent liver resection alone or followed by postoperative adjuvant transcatheter arterial chemoembolization. A: OS for HCC/MVI (-) patients (P = 0.872); B: OS for HCC/MVI (+) patients (P = 0.019); C: RFS for HCC/MVI (-) patients (P = 0.974); D: RFS for HCC/MVI (+) patients (P = 0.002). OS: Overall survival; HCC: Hepatocellular carcinoma; MVI: Microvascular invasion; RFS: Recurrence-free survival.
