Statistical analysis showed that the positive expression of OR2T6 was tightly associated with lymph node metastasis (p = 0.002) and higher TNM (Tumor/Node/Metastasis) staging (p = 0.033), but not with patients' age, tumor size, or histological grade (Table 2). The gene discussed is OR2T6; the disease is metastatic malignant neoplasm in the lymph nodes.
