Cohort study 

研究目的:

本研究拟基于单中心真实世界队列,系统评估乳腺癌患者在新辅助治疗前后雌激素受体(ER)、孕激素受体(PR)、人表皮生长因子受体2(HER2)、Ki-67及雄激素受体(AR)的动态变化特征,分析其转换率及变化方向,并进一步探讨上述生物标志物变化与病理完全缓解(pCR)、Miller-Payne(MP)评分及术后腋窝淋巴结病理状态(ypN)之间的关系。同时,在未达到pCR的残余病灶患者中,进一步分析Ki-67动态变化与病理反应程度的相关性,并评价AR表达及其动态变化对新辅助治疗疗效的预测价值,从而为乳腺癌新辅助治疗后残余病灶的再评估及后续个体化治疗提供依据。  

Objectives of Study:

This study aims to systematically evaluate the dynamic changes in estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), Ki-67, and androgen receptor (AR) before and after neoadjuvant therapy in patients with breast cancer based on a single-center real-world cohort. It further aims to analyze the conversion rates and directions of these biomarkers and to explore their associations with pathological complete response (pCR), Miller-Payne (MP) grade, and postoperative pathological lymph node status (ypN). In addition, among patients with residual disease after neoadjuvant therapy, this study will further investigate the relationship between dynamic Ki-67 changes and pathological response, and evaluate the predictive value of baseline AR expression and its dynamic change for treatment efficacy. The ultimate goal is to provide evidence for biomarker reassessment and individualized postoperative treatment strategies in breast cancer.

本研究采用回顾性数据采集方式。研究数据主要来源于医院电子病历系统、病理系统及相关临床检查记录。研究者依据预设的数据提取表收集患者基线临床病理资料、治疗前空芯针穿刺病理资料、术后手术标本病理资料及疗效评价指标。所有数据录入后由两名研究人员进行核对与质控,发现疑问时通过原始病历及病理报告回查确认。数据在分析前进行匿名化和去标识化处理,并存储于受密码保护的电子数据库中,仅限研究团队授权成员访问,以确保数据完整性、准确性和安全性。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

This study uses retrospective data collection. Data are obtained mainly from the hospital electronic medical record system, pathology system, and related clinical examination records. Investigators will collect baseline clinicopathological characteristics, pre-treatment core needle biopsy data, post-operative pathological findings, and treatment response indicators using a predefined data extraction form. After data entry, two researchers will independently verify and perform quality control. Any discrepancies will be checked against the original medical records and pathology reports. Before analysis, all data will be anonymized and de-identified and stored in a password-protected electronic database accessible only to authorized study personnel to ensure data integrity, accuracy, and security.
