CPSF4 and metastatic malignant neoplasm in the lymph nodes: We also used a univariate analysis to evaluate associations between patient prognosis and several clinicopathologic factors including CPSF4 expression (high vs. low), gender (male vs. female), age (≥60 vs. <60 years), pT stage (tumor size; T3-T4 vs. T1-T2) and pN stage (lymph node metastasis; N2-N3 vs. N0–N1).
