Abstract:Objective: To analyze the correlation between connexin 45 (Cx45) and clinicopathological features and prognosis of colorectal cancer patients. Methods: 97 patients with colorectal cancer admitted to our hospital from January 2016 to January 2019 were selected, and the expression levels of Cx45 in their focus tissues, adjacent tissues, and metastatic lymph nodes were detected by tissue microarray technology. The expression differences of Cx45 in focus tissues of patients with different clinicopathological features and different prognoses were compared, and the relationship between the expression characteristics of Cx45 in focus tissues and clinical pathological features and prognosis of patients were analyzed. Results: A total of 97 lesions, 97 adjacent tissues and 86 metastatic lymph node tissues were obtained. The high expression rate of Cx45 in lesions and metastatic lymph nodes was higher than that in adjacent tissues, and the low expression rate was lower than that in adjacent tissues, with statistical significance (P<0.05). The expression of Cx45 in rectal cancer patients with different lymph node metastasis, different degree of differentiation, and different TNM staging rhythm was statistically significant (P<0.05). The overall survival time (OS) and disease-free survival time (PFS) of patients with high expression of Cx45 were shorter than those with low expression of Cx45, and the difference was statistically significant (P<0.05). Cox regression model showed that lymph node metastasis, low differentiation degree, TNM stage Ⅲ ~ Ⅳ, and high expression of Cx45 in lesion tissues were independent risk factors for OS in patients with colorectal cancer (P<0.05). Conclusion: The expression of Cx45 in colorectal cancer patients with different lymph node metastasis status, differentiation degree, and TNM stage are significantly different. Besides the clinicopathological features, the high expression of Cx45 in colorectal cancer patients is also directly related to the shortening of OS.
