Cohort study 

研究目的:

主要目的: 探讨基于多模态超声(二维、血流、弹性、造影)的动态特征变化能否早期、准确预测乳腺癌新辅助治疗后的病理学反应(主要终点为pCR)。 次要目的:比较多模态超声与DCE-MRI在评估新辅助治疗疗效方面的一致性及相关性。筛选出对预测pCR最具价值的超声影像学标志物(如造影参数、弹性值变化率等)。开发和验证一个基于多模态超声动态特征的机器学习预测模型,用于个体化预测患者达到pCR的概率。  

Objectives of Study:

Primary Objective:To explore whether dynamic characteristic changes based on multimodal ultrasound (including 2D-ultrasonography, blood flow imaging, elastography and contrast-enhanced ultrasound) can early and accurately predict the pathological response to neoadjuvant therapy in breast cancer, with pathological complete response (pCR) set as the primary endpoint.Secondary Objectives:To compare the consistency and correlation between multimodal ultrasound and DCE-MRI in evaluating the efficacy of neoadjuvant therapy.To screen out ultrasound imaging biomarkers with the highest predictive value for pCR, such as contrast-enhanced parameters and the change rate of elastic values.To develop and validate a machine learning prediction model based on dynamic multimodal ultrasound features for individualized prediction of the probability of achieving pCR in patients.
