Context: To compare the efficacy and safety of microwave ablation (MWA) versus MWA combined with I125 seed implantation for the treatment of post-transcatheter arterial chemoembolization (TACE) residual lesions of primary liver cancer. Methods: A total of 38 patients with post-TACE residual lesions of liver cancer only received MWA, whereas 33 patients received combined treatment of MWA with I125 seed implantation. Enhanced magnetic resonance imaging (MRI) or positron emission tomography/computed tomography (PET/CT) was performed for review at 1, 3, and 6 months after treatment to observe and compare the short-term efficacy and complications between the two groups. Results: The tumor complete response (CR) rate of the MWA group after treatment was 55.3% (21/38) and that of the MWA + I125 group was 81.8% (27/33), indicating a significantly higher value than that of the MWA group (P < 0.05). There was no difference in the minor complications between the two groups, and no serious complications were recorded. Conclusions: MWA combined with I125 seed implantation for the treatment of post-TACE residual lesions of primary liver cancer is safe and effective, and its efficacy is better than that of the simple MWA treatment.
