As illustrated in Table 2, we found that PCAT19 expression was related to tumor size and pathology (P < 0.05), but not associated with age (P = 0.859), gender (P = 0.719), clinical stage (P = 0.423), or lymph node metastasis (P = 0.370). Here, PCAT19 is linked to metastatic malignant neoplasm in the lymph nodes.
