The correlation between STEAP1 expression and clinical variables (age, gender, differentiation, tumor size, lymph node metastasis, distant metastasis, tumor stage) showed that lymph node metastasis, distant metastasis and tumor stage can significantly affect STEAP1 expression (P<0.05, Table 1). The gene discussed is STEAP1; the disease is metastatic malignant neoplasm in the lymph nodes.
