Abstract:
Objective To investigate the clinical significances of the expressions of Yes-associated protein 1 (YAP1) and collagen triple helix repeat containing 1 (CTHRC1) in triple-negative breast cancer (TNBC) and their correlations with expression of E-cadherin. Methods Immunohistochemical analysis (SABC) was performed to detect expressions of YAP1 and CTHRC1 in 73 specimens of TNBC and adjacent cancer tissues collected from patients in Dandong First Hospital from January 2006 to December 2017. The correlations between the expressions of YAP1 and CTHRC1 and clinicopathologic features and E-cadherin expression were analyzed. Results The expression rates of YAP1 and CTHRC1 in TNBC were 71.23％(52/73) and 79.45％(58/73), and 13.70％(10/73) and 27.40％(20/73) in adjacent cancer tissues, respectively, and the differences were statistically significant (χ2 values were 49.452 and 39.748, both P< 0.01). The expressions of YAP1 and CTHRC1 were related to tumor grade, clinical stage and lymphatic metastasis (YAP1:χ2 values were 10.244, 8.754, and 6.914, all P<0.05;CTHRC1:χ2 values were 12.582, 13.172, and 6.400, all P< 0.05), but they were not related to patient's age, tumor diameter and menopausal status (all P>0.05). The expressions of YAP1 and CTHRC1 were negatively correlated with expression of E-cadherin in TNBC (r=-0.371, P=0.001;r=-0.323, P=0.005). Conclusion YAP1 and CTHRC1 is closely related to the occurrence and development of TNBC and may participate in the invasion of TNBC through epithelial mesenchymal transition.
