Conversion of ER, PR, HER2 and Ki-67 and Prognosis in breast cancer metastases to the brain

2022-06-06

Abstract excerpt

<h4>Objective: </h4> This study aimed to analyze the expression levels of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER-2), and Ki-67 proliferation index in the brain metastatic lesions and primary lesions in Chinese patients with breast cancer brain metastasis (BCBM) and determine the correlation between their changes and patients’ survival. Methods A retrospec...
