Most prior observational research of traditionally HER2-negative patients suggests that tumor behavior and biology do not vary according to HER2-low vs. HER2-0 expression, though some studies suggest otherwise. Here we studied this question in women with metastatic breast cancer (MBC) who were treated with standard single agent chemotherapy in the setting of clinical trials carried out in the pre-DESTINY-04 era. After pooling data from 142 female patients with MBC across historic clinical trials and categorizing them according to HER2 expression (i.e., HER2-0 or HER2-low), we evaluated associations between HER2 expression and the outcomes of both progression-free survival (PFS) and overall survival (OS) with both Kaplan-Meier and Cox proportional hazards methods.
