Univariate analysis showed that the RFS in all 129 cases was significantly influenced by lymph node metastasis (P<0.001), large tumor size (P<0.001), low Hb level (P=0.011), and AURKA expression level (P<0.001) (Table 3). The gene discussed is GSTM1; the disease is metastatic malignant neoplasm in the lymph nodes.
