Fig. 2From: The study of direct and indirect effects of radiofrequency ablation on tumor microenvironment in liver tumor animal modelComparison of tumor growth rate in mice bearing H22 liver tumor. The tumor growth curves showed the residual tumor grew faster in the direct RFA group than the indirect RFA group (P = 0.026). The tumor growth rate in the control group was the slowest compared with that in the direct RFA group (P < 0.001) and indirect RFA group (P = 0.042). *P < 0.05, **P < 0.01Back to article page
