Methods: This retrospective study was institutional review board approved. A total of 121 patients (102 men and 19 women) with 136 ICCs after hepatectomy from April 2011 to January 2017 were reviewed. Fifty-six patients underwent US-PMWA and 65 patients underwent SR. Survival, recurrence and liver function were compared between the two groups. Effect of changes in key parameters [i.e., overall survival (OS) and recurrence-free survival (RFS)] was statistically analyzed with the log-rank test. Univariate and multivariate analysis were performed on clinicopathological variables to identify factors affecting long-term outcome. Results: The OS and RFS after MWA were comparable to that of SR (p£¿=£¿.405, and p£¿=£¿.589, respectively). Estimated 5-year OS rates were 23.7% after MWA and 21.8% after SR; for RFS, estimated 3-year RFS rates were 33.1% after MWA and 30.6% after SR. Major complication rates in SR group were higher than that in MWA (p£¿<£¿.001) (SR, 13.8% vs. MWA, 5.3%). Multivariate analysis showed tumor number (p£¿=£¿.012), ALBI grade (p£¿=£¿.007), and metastasis (p£¿=£¿.016), may become OS rate predictors. Conclusions: US-PMWA had comparable oncologic outcomes with SR and could be a safe and effective treatment for recurrent ICC after hepatectomy %U https://www.tandfonline.com/doi/full/10.1080/02656736.2019.1571247
