研究目的:

1.主要研究目的 客观缓解率(ORR)、乳腺病理完全缓解率(bpCR)、降期手术成功率以及远期无病生存率(DFS)、总生存率(OS)指标,评估CDK4/6抑制剂联合新辅助内分泌治疗策略对新辅助化疗不敏感的HR+HER2-亚型,cT4/N2-3M0的不可手术乳腺癌患者的影响。 2. 次要研究目的或探索性研究目的 2.1. 通过分析新辅助内分泌治疗后12周及及治疗24周后(术前)的循环肿瘤细胞(CTC)及循环肿瘤基因(ctDNA)、完全细胞周期停滞率(CCCA,定义为Ki-67≤2.7%),评估早期新辅助内分泌治疗疗效; 2.2. 通过分析术后的内分泌治疗敏感性疾病率,评估ESDR是否可以替代以上指标预测患者远期生存(DFS及OS); 2.3. 探索术后ESDR、ORR、bpCR结果是否可以指导患者后续治疗方案; 2.4. 探索新辅助内分泌敏感患者与新辅助化疗敏感患者基因表达等特征的区别,以此进行新辅助治疗(新辅助内分泌治疗及新辅助化疗)敏感人群的基因预测模型的建立。  

Objectives of Study:

1. Main research objectives Objective response rate (ORR), breast pathological complete response rate (bpCR), success rate of downstaging surgery, and long-term disease-free survival (DFS) and overall survival (OS) indicators, to evaluate the effect of CDK4/6 inhibitor combined with neoadjuvant endocrine therapy strategy on patients with HR+HER2- subtype, cT4/N2-3M0 inoperable breast cancer who are insensitive to neoadjuvant chemotherapy. 2. Secondary or exploratory research objectives 2.1. Evaluate the efficacy of early neoadjuvant endocrine therapy by analyzing circulating tumor cells (CTCs) and circulating tumor genes (ctDNA) 12 weeks after neoadjuvant endocrine therapy and 24 weeks after treatment (before surgery), and complete cell cycle arrest rate (CCCA, defined as Ki-67 ≤ 2.7%); 2.2. Evaluate whether ESDR can replace the above indicators to predict long-term survival (DFS and OS) of patients by analyzing the postoperative endocrine therapy-sensitive disease rate; 2.3. Explore whether the postoperative ESDR, ORR, and bpCR results can guide the subsequent treatment plan of patients; 2.4. Explore the differences in gene expression and other characteristics between neoadjuvant endocrine-sensitive patients and neoadjuvant chemotherapy-sensitive patients, so as to establish a gene prediction model for the population sensitive to neoadjuvant therapy (neoadjuvant endocrine therapy and neoadjuvant chemotherapy).
