Analyses of the correlation between UCA1 expression and gastric cancer patients’ clinical pathological features showed that increased UCA1 expression was correlated with gastric cancer TNM stage and lymph node metastases, with no other correlation found between UCA1 expression and other gastric cancer clinical pathological features, including the patients’ sex, age, tumor size, and degree of differentiation (Table 1). Here, UCA1 is linked to gastric cancer.
