Sumario:BACKGROUND: Esophageal cancer is the eighth most frequent and sixth most fatal cancer worldwide. This study aimed to investigate the clinical characteristics and prognostic significance of yes related protein 1 (YAP1) and transcriptional co-activator with PDZ binding motif (TAZ) in patients with esophageal squamous cell carcinoma (ESCC). METHODS: A total of 306 ESCC pathological specimens and adjacent tissues (as control; tissues from the esophageal mucosa >5 cm from the edge of the tumor) were collected between January, 2008 and December, 2018. Immunohistochemical staining was used to assess the expression of YAP1 and TAZ proteins in the ESCC and adjacent tissues, and their relationship with clinicopathological parameters was evaluated using SPSS 21.0 software. RESULTS: YAP1 and TAZ proteins were highly expressed in ESCC, and their expression was closely related to TNM stage and lymph node metastasis. Expression of YAP1 was associated with tumor size (P = .029), differentiation (P = .000), depth of invasion (P = .001), and TNM stage (P = .000). Expression of TAZ was associated with tumor size (P = .034), differentiation (P = .000), depth of invasion (P = .029), lymph node metastasis (P = .006), and ethnicity (P < .001). The expression of YAP1 protein was positively correlated with the expression of TAZ protein (r = 0.257, P < .05). YAP1 and TAZ expression (P = .039 and .000, respectively), tumor size (P = .041), and lymph node metastasis (P = .001) significantly affected the overall survival of patients with ESCC, and represent independent factors for overall survival. CONCLUSION: YAP1 and TAZ proteins are highly expressed in ESCC, and closely related to the clinical and pathological parameters such as the diameter of the tumor, degree of differentiation, and depth of invasion, indicating that YAP1 and TAZ may be involved in the development of ESCC. YAP1 and TAZ may be used as prognostic markers in ESCC.
