Abstract:
Objective:To explore the expression and clinical significance of KIF20A in HER2-positive breast cancer.Methods:The clinicopathological characteristics of 82 cases of HER2-positive breast cancer were retrospectively analyzed. The expression of KIF20A in tissues was detected by immunohistochemical method, and the expression of KIF20A in HER2 overexpression breast cancer and its relationship with clinicopathological characteristics were analyzed. The mRNA level of KIF20A in HER2-positive breast cancer tissues and normal tissues adjacent to cancer were analyzed by bioinformatics methods.Results:The positive expression of KIF20A was in the nucleus, forming brown-yellow particles. In HER2-positive breast cancer tissues, the positive high expression rate of KIF20A is 57.3%, while it is mainly low or no expression in the adjacent tissues. The high expression of KIF20A is significantly correlated with tumor size and pTNM stage, while the correlation with age and tumor grade is not statistically significant. The results of bioinformatics analysis suggest that the high expression of KIF20A in invasive breast cancer is significantly related to poor disease-free survival.Conclusions:KIF20A is abnormally expressed in HER2-positive breast cancer, which is related to the tumor grade and pTNM stage of HER2 overexpression breast cancer, and the high expression of KIF20A indicates a poor prognosis.
