Efficacy and safety of transcatheter arterial chemoembolization combined with microwave ablation for hepatic hemangiomas (> 5 cm)

Figure 1 This figure compares the transcatheter arterial chemoembolization group and the transcatheter arterial chemoembolization + microwave ablation group at 12 months and > 3 years. The top charts display the complete response and objective response rate, illustrating significantly higher values for transcatheter arterial chemoembolization (TACE) + microwave ablation (MWA) at 12 months (P < 0.001) and a trend toward better outcomes at > 3 years (P = 0.059). The lower charts show the tumor diameter at 12 months: TACE + MWA achieved significantly greater tumor reduction (P < 0.05), whereas at > 3 years, the difference was not statistically significant (P = 0.29). These findings highlight the enhanced early tumor control and suggest a sustained long-term clinical benefit using the TACE + MWA combination. CR: Complete response; MWA: Microwave ablation; ORR: Objective response rate; TACE: Transcatheter arterial chemoembolization.
