We performed correlation analysis between ZFAS1 expression and various clinico-pathological features, and we have not observed any association of ZFAS1 expression with clinical stage, lymph node metastasis, distant metastasis, grade, tumor diameter and survival in our cohort (P > 0.05, data not shown). The gene discussed is ZFAS1; the disease is metastatic malignant neoplasm in the lymph nodes.
