About

This study aims to evaluate the predictive value of the tumor vascular normalization score for the efficacy of neoadjuvant therapy in HER-2-positive breast cancer and explore its potential as a predictive biomarker. Through longitudinal observation of HER-2-positive breast cancer patients receiving standard treatment, we will analyze the correlation between vascular normalization scores and treatment responses (including objective response rate [ORR] and pathological complete response [pCR]) to optimize individualized therapeutic strategies. Additionally, an exploratory investigation will assess the impact of ginsenoside-containing formulations (e.g., Jinxing Capsule, Shenyi Capsule, Yiqi Jianpi Oral Liquid) on tumor vasculature and neoadjuvant therapy outcomes in HER-2-positive breast cancer, providing scientific insights for complementary therapeutic interventions.

HER2 positive breast cancer

Description:

Female breast cancer patients with histopathologically confirmed HER2-positive status (defined as HER2 immunohistochemistry \[IHC\] 3+ or HER2 IHC 2+ with positive confirmation by fluorescence in situ hybridization \[FISH\]) who are planned to receive neoadjuvant therapy, including chemotherapy and HER2-targeted regimens.
