Twenty related risk factors, including gender, age, comorbidity scores, biochemical parameters, and blood routine before treatment like alanine transaminase (ALT)-pre, glutamic oxaloacetic transaminase (AST)-pre, ALB-pre, STB-pre, Cr-pre, Hb-pre, platelet (PLT)-pre, white blood cell (WBC)-pre, lymphocyte (LY)-pre, red blood cell (RBC)-pre, the location of tumor, the maximum diameter of tumor, MWA energy, MWA time, and the number of antenna insertions, were analyzed using the univariate and multivariate logistic regression model method. The gene discussed is GSTM1; the disease is neoplasm.
