The correlational analysis between LINC00355 expression and clinicopathological factors of gastric cancer patients determined that higher LINC00355 expression levels were significantly correlated with advanced pathologic stage (P = 0.000), invasion depth (P = 0.000), and distant metastasis (P = 0.029) in gastric cancer patients, but it was not correlated with other factors, including histologic differentiation, lymphatic metastasis, sex, and age (Table 1). The gene discussed is LINC00355; the disease is gastric cancer.
