We also performed univariate and multivariate Cox regression analyses of GSTM2 protein expression and clinical characteristics, and the results showed that the p value of GSTM2 protein level in infiltrating lymphocytes within tumor tissues was less than 0.05, which indicated that GSTM2 was potentially an independent prognosis factor for colon cancer (Table 2). The gene discussed is GSTM2; the disease is neoplasm.
