Abstract

Purpose To identify and compare predictors of local tumor progression free survival (LTPFS) after radiofrequency ablation (RFA) and microwave ablation (MWA) of colorectal liver metastases (CLM). Methods This is a retrospective review of CLM ablated from November 2009 to April 2015 (110 patients). Margins were measured on contrast-enhanced CT 6 weeks post-ablation. Clinical and technical predictors of LTPFS were assessed using a competing risk model adjusted for clustering. Results Technique effectiveness (complete ablation) was 93% (79/85) for RFA and 97% (58/60) for MWA (P=0.47). The median follow-up period was significantly longer for RFA versus MWA (56 versus 29 months) (P<0.001). There was no difference in the LTP rates between RFA and MWA (P=0.84). Significant predictors of shorter LTPFS for RFA on univariate analysis were ablation margin ≤5 mm (P<0.001) (HR: 14.6; 95% CI: 5.2–40.9) and peri-vascular tumors (P=0.021) (HR: 2.2; 95% CI: 1.1–4.3); both retained significance on multivariate analysis. Significant predictors of shorter LTPFS on univariate analysis for MWA were ablation margin ≤5 mm (P<0.001) (SHR: 11.6; 95% CI: 3.1–42.7) and no history of prior liver resection (P<0.013) (HR: 3.2; 95%: 1.3–7.8); both retained significance on multivariate analysis. There was no LTP for tumors ablated with margin over 10 mm (median LTPFS: not reached). Peri-vascular tumors were not predictive for MWA (P=0.43). Conclusion Regardless of the thermal ablation modality used, margins >5 mm are critical for local tumor control, with no LTP noted for margins over 10 mm. Unlike RFA, the efficiency of MWA was not affected for peri-vascular tumors.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
