Among them, 91 patients received C-TACE-A, and 96 patients received D-TACE-A. The primary endpoint was overall survival (OS), and the secondary endpoints were progression-free survival (PFS) and disease control rate (DCR). Propensity score matching (PSM) was used to reduce selection bias.Results: Before PSM, the median OS was 15 months (95% CI: 12.5– 17.5) and 13 months (95% CI: 11.1– 14.9; P=0.480) in the C-TACE-A and D-TACE-A groups, respectively. The median PFS was 7 months (95% CI: 5.9– 8.1) in the C-TACE-A group and 7 months (95% CI: 5.6– 8.4; p=0.677) in the D-TACE-A group. The DCR was 81.3% in the C-TACE-A group and 72.9% in the D-TACE-A group. Cox regression analysis showed that D-TACE-A did not increase mortality risk or tumor recurrence risk. After PSM, there was no statistically significant difference in median OS or PFS between the two groups. In the subgroup analysis, after adjusting for relative factors, D-TACE-A increased the mortality risk more than C-TACE-A in patients with BCLC stage C (HR: 1.678, 95% CI: 1.129– 2.495; P=0.011), but D-TACE-A lowered the tumor recurrence risk compared with C-TACE-A in patients with Child–Pugh B (HR: 0.210, 95% CI: 0.082– 0.538; P=0.001) and cirrhosis (HR: 0.481, 95% CI: 0.293– 0.791; P=0.004). Grade III and IV adverse events in patients with D-TACE-A were similar to those in patients treated with C-TACE-A (P> 0.05).Conclusion: Patients with unresectable HCC treated with D-TACE-A might not show increased survival compared with patients treated with C-TACE-A. Advanced HCC patients without cirrhosis may receive greater survival benefits from C-TACE-A than D-TACE-A.Keywords: hepatocellular carcinoma, drug-eluting beads transarterial chemoembolization, conventional transarterial chemoembolization, apatinib, efficacy |
