研究目的:

本研究旨在探索 18F-FDG PET/CT 预测 HER2 阳性早期或局部晚期乳腺癌新辅助治疗的疗效并指导治疗 2 周期后疗效欠佳患者新辅助治疗方案选择的效用,从而提高新辅助治疗的病理学完全缓解(pCR)率,改善患者预后。通过对比新辅助 TIPy 方案治疗 2 周期后 18F-FDG PET/CT 的 SUVmax 下降率,来指导后续 4 个周期的新辅助治疗方案,验证 18F-FDG PET/CT 预测并指导新辅助治疗方案选择的效用,改善患者的整体预后。  

Objectives of Study:

The purpose of this study is to explore the utility of 18F-FDG PET/CT in predicting the efficacy of neoadjuvant therapy for HER2-positive early or locally advanced breast cancer and guiding the selection of neoadjuvant treatment regimens for patients with suboptimal response after 2 cycles of treatment, thereby improving the pathological complete response (pCR) rate of neoadjuvant therapy and patient prognosis. By comparing the SUVmax decline rate of 18F-FDG PET/CT after 2 cycles of neoadjuvant TIPy regimen, this study aims to guide the selection of subsequent 4-cycle neoadjuvant treatment regimens, validate the utility of 18F-FDG PET/CT in predicting and guiding neoadjuvant treatment selection, and improve the overall prognosis of patients.
