Multivariable cox regression analysis showed that tumor diameter, MWA power (High), tumor differentiation (Poor), EGFR mutations, and SIRI (High) were independent related factors for OS (hazard ratio [HR] 2.271, P<0.001; HR 0.510, P=0.010; HR 3.983, P<0.001; HR 0.151, P<0.001 and HR 2.583, P<0.001, respectively; Table 2). Here, EGFR is linked to neoplasm.
