Figure 1:
Comparison of effect of paclitaxel (PTXL) timing (either before RF ablation [pre-RF] or after RF ablation [post-RF]) on tumor coagulation over time. Tumor coagulation increased over time for both groups (paclitaxel–RF ablation and RF ablation–paclitaxel) to a similar maximum amount at 96 hours (P = .16). More rapid response was observed for paclitaxel–RF ablation, which had the greatest rate of mean increase in coagulation area occurring earlier (4–24 hours, 352.5 mm2 ± 81.2) compared with that at later time (24–72 hours, 258.9 mm2 ± 158.9) for RF ablation–paclitaxel.
