Microwave ablation (MWA) provides a promising treatment for liver tumor. This study aimed to evaluate the therapeutic efficacy of reconstructed CT–guided MWA in liver tumors. A retrospective study was conducted for 52 liver tumors (2.24 ± 0.84 cm, 0.8–4.0 cm) in 49 patients (29 men and 20 women; 59.7 ± 12.0 years) who were treated with reconstructed CT-guided MWA from February 2015 to September 2015. Baseline characteristics of patients and tumors were recorded, and technical details were depicted. Technical success and technique efficacy were evaluated. In results, MWA was performed in all patients successfully (n=49), and the complete ablation rate was 100% (52/52). Mean followup time was 10.1 ± 2.5 months (range, 6–15 months). Cumulative local tumor recurrence (LR) was 1.9% (1/52), 5.8% (3/52), and 7.7% (4/52) at 1, 3, and 6 months respectively. Cumulative distant recurrence (DR) was 3.8% (2/52), 7.7% (4/52), and 7.7% (4/52) at 1, 3, and 6 months respectively. Until May 2016, all patients were conscious and alive. In conclusion, reconstructed CT-guided MWA is feasible with high technique efficacy in the treatment of hepatic tumors.
