Predictive, Prognostic evidence:
Predictive: The study discusses the effectiveness of trastuzumab deruxtecan in patients with HER2-low metastatic breast cancer, indicating that the variant correlates with response to this specific therapy, as evidenced by the significant differences in progression-free survival and overall survival between treatment groups.
Prognostic: The results show that patients with HER2-low metastatic breast cancer had different overall survival rates based on the treatment received, suggesting that the HER2-low status is associated with disease outcomes independent of therapy.
