Univariate analysis results demonstrated that invasion depth (P = .021), lymph node metastasis (P = .030), FEZF1‐AS1 expression levels (P = .001), distant metastasis (P = .003), TNM stage (P < .001) were closely related to OS (Table 2). The gene discussed is FEZF1; the disease is metastatic malignant neoplasm in the lymph nodes.
