Analysis of Exploring Optimized Sequential Treatment Strategies of Antibody-Drug Conjugates (ADCs) in HER2-Low-Expressing Breast Cancer

Sponsor: Sun Yat-sen University

Summary

This study retrospectively analyzes the clinical data of HER2-low breast cancer (IHC 1+/2+ and FISH-negative) patients treated with sequential antibody-drug conjugates (ADCs). Key variables include patient demographics, tumor characteristics, ADC regimens (e.g., trastuzumab deruxtecan, sacituzumab govitecan), treatment sequencing, survival outcomes, and safety profiles. Genomic data (e.g., HER2 expression dynamics, TROP2 levels) are integrated to explore resistance mechanisms and prognostic biomarkers.mechanisms. This study aims to investigate the efficacy of different ADC sequential regimens in HER2-low breast cancer patients.
