To reduce bias in patient selection, the different covariate distributions in two groups were adjusted using inverse probability treatment weighting (IPTW).

Five\u2010year recurrence\u2010free survival (RFS) was significantly better in the LR group than in the RFA group (<jats:italic>P<\/jats:italic> &lt; 0.0001). Multivariate analysis showed that RFA was an independent predictor of worse RFS (<jats:italic>P<\/jats:italic> = 0.0004). The local recurrence rate was higher in the RFA than in the LR group, with recurrences in each group tending to be treated with the same modality as initially. After IPTW adjustment, the OS of patients in the LR and RFA groups did not significantly differ, whereas the RFS of the LR group remained significantly better than that of the RFA group (<jats:italic>P<\/jats:italic> = 0.00014).
