CEACAM5 and colorectal carcinoma: The correlation between YAP expression in CRC tissues and clinicopathologic features is as follows: YAP expression level was closely related to serosal invasion (P=0.040), lymphatic metastasis (P=0.013), the lymph node ratio (LNR; P=0.035), remote metastasis (P=0.020), Dukes stage (P=0.033), and the CEA (P=0.011) (Table 1).
