Repeated Hepatic Resection versus Radiofrequency Ablation for Recurrent XXXX after Hepatic Resection: A Propensity Score Matching Study.

@entity1 @entity157 @entity5 @entity1349
UNASSIGNED: Purpose To compare the long-term outcomes of repeated hepatic resection and radiofrequency (RF) ablation for recurrent @entity157 ( @entity157 ) by using propensity score matching. Materials and Methods This retrospective study was approved by the institutional review board, and the requirement to obtain informed consent was waived. Thirty-nine @entity1 who underwent repeated hepatic resection and 178 who underwent RF ablation for recurrent @entity157 (mean @entity5 size    standard deviation, 1.8 cm    0.7) between November 1994 and December 2012 were included in the study. @entity1 ranged in age from 24 to 85 years (mean, 54.9 years). @entity1 ranged in age from 25 to 85 years (mean, 54.8 years), and @entity1 ranged in age from 24 to 76 years (mean, 55.4 years). A 1:2 repeated hepatic resection group-RF ablation group matching was done by using propensity score matching. The @entity1349 ( @entity1349 ) and disease-free survival (DFS) were compared before and after propensity score matching. Complications were assessed. Results Before matching, @entity1349 rates at 1, 3, 5, and 8 years were 88.8%, 88.8%, 83.9%, and 56.3%, respectively, with repeated hepatic resection and 98.9%, 82.5%, 71.0%, and 58.3% for RF ablation. DFS rates at 1, 3, and 5 years were 66.1%, 48.5%, and 43.1% for repeated hepatic resection and 70.1%, 40.8%, and 30.0% for RF ablation. After matching, the @entity1349 rates at 1, 3, 5, and 8 years were 98.7%, 85.7%, 72.1%, and 68.6%, respectively, and the DFS rates at 1, 3, and 5 years were 71.8%, 45.1%, and 39.4% in the RF ablation group (n = 78). Neither the @entity1349 nor DFS rate was significantly different between the two groups before matching (P = .686 and P = .461) and after matching (P = .834 and P = .960). The postoperative mortality rate was 2.6% in the repeated hepatic resection group and 0% in the RF ablation group. Conclusion The long-term @entity1349 and DFS were not significantly different between repeated hepatic resection and RF ablation for @entity1 with recurrent @entity157 after hepatic resection.
