Meanwhile, positive and strongly positive expression rates of SERPIND1 were higher in the lymph node metastasis–positive group than in the lymph node metastasis–negative group, but the differences were not statistically significant (100 and 82.4% vs. 94.6 and 76.8%, P > 0.05 in all cases). The gene discussed is SERPIND1; the disease is metastatic malignant neoplasm in the lymph nodes.
