研究目的:

本研究旨在评估在标准 TCbHP 方案(多西他赛 + 卡铂 + 曲妥珠单抗 + 帕妥珠单抗)基础上加用吡咯替尼对疗效不佳的 HR 阳性 HER2 阳性早期乳腺癌患者的有效性和安全性,并探索生物标志物对治疗反应的预测价值。具体如下: 1.探索优化治疗方案:筛选经 2 周期 TCbHP 新辅助化疗疗效不佳(肿瘤退缩 < 50%)的 HR 阳性 HER2 阳性早期乳腺癌患者,对比继续使用标准 HP 双靶向治疗和采用 TCbHP + 吡咯替尼三靶向治疗方案,探索针对此类患者更优的新辅助治疗方案; 2.评估有效性和安全性:明确在标准 TCbHP 方案基础上加用吡咯替尼,对疗效不佳患者治疗的有效性和安全性。通过设置对照组和试验组,以总病理完全缓解率(tpCR)为主要终点,无事件生存期(EFS)、安全性等为次要终点进行评估,为临床治疗提供可靠依据; 3.探索生物标志物预测价值:全面分析 Ki67、PAM50、HER2DX、PIK3CA 突变率、肿瘤浸润淋巴细胞、PD-L1 表达水平以及 FISH 检测(HER2 与 CEP17 的比值)等生物标志物。结合临床病理特征,多维度预测不同抗 HER2 靶向治疗策略的潜在受益者,从而为临床医生制定精准治疗决策提供支持。  

Objectives of Study:

This study aims to evaluate the efficacy and safety of adding pyrotinib to the standard TCbHP regimen (docetaxel + carboplatin + trastuzumab + pertuzumab) in HR-positive, HER2-positive early-stage breast cancer patients with poor treatment response. And explores the predictive value of biomarkers for treatment response. Details:1.Explore optimized treatment regimens: Identify HR+/HER2+ early-stage breast cancer patients with inadequate response (tumor shrinkage <50%) after 2 cycles of TCbHP neoadjuvant chemo. Compare continuing standard HP dual-targeted therapy vs. TCbHP + pyrotinib triple-targeted therapy to find a superior neoadjuvant regimen for this subset.2.Evaluate efficacy and safety: Determine the efficacy and safety of adding pyrotinib to standard TCbHP in poor responders. Via control and experimental groups, assess outcomes with total pathological complete response (tpCR) as the primary endpoint and event-free survival (EFS), safety, and other factors as secondary endpoints to provide reliable clinical guidance.3.Explore biomarker predictive value: Comprehensively analyze biomarkers including Ki67, PAM50, HER2DX, PIK3CA mutation rate, tumor-infiltrating lymphocytes, PD-L1 expression levels, and FISH testing (HER2/CEP17 ratio). Combine with clinicopathological characteristics to multidimensionally predict potential beneficiaries of different anti-HER2 targeted therapy strategies, aiding clinicians in precision treatment decisions.
