title: Early cytokine responses after percutaneous magnetic resonance imaging guided laser thermoablation of malignant liver tumors.
abstract: An early systemic response induced by magnetic resonance imaging (MRI)-guided interstitial percutaneous laser thermoablation was analyzed in 13 consecutive patients with malignant liver tumors by serum interleukin (IL)-1beta, IL-6, IL-10, tumor necrosis factor (TNF)-alpha, its receptor TNFRI, and C-reactive protein (CRP) levels up to 72h after the procedures. Only IL-6 (p=0.033) and TNFRI (p<0.001) increased statistically significantly after ablation, while the TNF-alpha, IL-1 beta, and IL-10 levels remained unchanged. The peak median CRP response was 92mg/l. There was a dose-dependent correlation between the energy used and the maximum CRP values (tau=0.68, p=0.013). MRI-guided laser thermoablation induced an early systemic inflammatory reaction with statistically significantly elevated IL-6, TNFRI, and CRP levels but not TNF-alpha or IL-10 levels and without procedure-related complications, favoring this procedure as a safe therapeutic alternative for well-selected patients with liver tumors.
