研究目的:

主要目的 评价 HP 双靶联合 AI 及库莫西利方案用于 HR+/HER2+ 早期乳腺癌新辅助治疗的病理完全缓解率(pCR,ypT0/is ypN0)。 次要目的 1. 评价残余肿瘤负荷 0-I 级(RCB 0-I)率。 2. 根据 RECIST 1.1 评估的客观缓解率(ORR)。 3. 评估无事件生存(EFS)。 4. 评价方案的安全性(CTCAE v5.0)。 探索性目的 基于基线肿瘤组织的 BluePrint? 等分子分型特征,探索肿瘤内在亚型(如 HER2-type、Luminal-type)与本方案新辅助治疗疗效(pCR/RCB)的相关性,以识别优势获益人群。  

Objectives of Study:

Primary Objective: To evaluate the pathological complete response (pCR, ypT0/is ypN0) rate of trastuzumab and pertuzumab (dual HER2 blockade) combined with AI and dalpiciclib as neoadjuvant therapy for HR+/HER2+ early breast cancer. Secondary Objectives: 1. To evaluate the Residual Cancer Burden (RCB) 0-I rate. 2. To evaluate the Objective Response Rate (ORR) according to RECIST 1.1. 3. To evaluate Event-Free Survival (EFS). 4. To evaluate the safety of the regimen (CTCAE v5.0). Exploratory Objective: To explore the correlation between tumor intrinsic subtypes (e.g., HER2-type, Luminal-type) based on baseline tumor tissue molecular profiling (e.g., BluePrint?) and neoadjuvant efficacy (pCR/RCB), aiming to identify the population with dominant benefits.
