Decreased BTG1 expression in gastric cancer was positively correlated with depth of invasion, lymphatic and venous invasion, lymph node metastasis, TNM staging and worse prognosis (Zhu et al., 2015), but the lower BTG1 expression in ovarian cancer was positively correlated with FIGO staging (Sheng et al., 2014). Here, BTG1 is linked to gastric cancer.
