Popis: | PURPOSE: Stereotactic body radiation therapy (SBRT) and radiofrequency ablation (RFA) are widely used therapies for the treatment of intrahepatic metastases; however, direct comparisons are lacking. We sought to compare outcomes for these 2 modalities. METHODS AND MATERIALS: From 2000 to 2015, 161 patients with 282 pathologically diagnosed unresectable liver metastases were treated with RFA (n = 112) or SBRT (n = 170) at a single institution. The primary outcome was freedom from local progression (FFLP). The effect of treatment and covariates on FFLP was modeled using a mixed-effects Cox model with application of inverse probability treatment weighting to adjust for potential imbalances in treatment modality. RESULTS: The median follow-up period was 24.6 months. Patients receiving SBRT had larger tumors than those treated with RFA (median, 2.7 cm vs 1.8 cm; P |
