Clinicopathological analysis indicated that PHF5A expression was not associated with patient’ age or gender, or histological grade, but positively correlated with tumor size (P = 0.015), lymph node metastasis (P = 0.002), and clinical stage (P = 0.003) (Table 1). The gene discussed is PHF5A; the disease is metastatic malignant neoplasm in the lymph nodes.
