The expression level of UCA1 in tumor tissues was positively associated with lymph node metastasis (P = 0.004), distance metastasis (P = 0.015) and higher TNM stage (P = 0.035), but not with other clinicopathological parameters including age, gender and T stage (Table 1). This evidence concerns the gene UCA1 and metastatic malignant neoplasm in the lymph nodes.
