HER-2 positive

These findings support a model in which CBD downregulates HER2 and, in a HER2-dependent context, promotes paraptosis and ferroptosis. In addition, docking and molecular dynamics analyses suggested a potential interaction between CBD and HER2, providing mechanistic insights into possible molecular recognition relevant to HER2-positive breast cancer.

In patients with BCBM, T-DXd-associated ILD/pneumonitis occurred in 10% of patient and frequently necessitated treatment modification. Although no fatal ILD was observed, the high discontinuation rate underscored the imperative for vigilant monitoring and protocol-guided management to mitigate pulmonary toxicity while preserving intracranial efficacy.

Higher HER2-HQE is associated with increased RCB. Quantifying HER2 heterogeneity via HQE and percentage of HER2 IHC 3+ may help optimize therapeutic strategies in clinical practice.

Tumor histology affects the real-world effectiveness of first line ET plus CDK4/6i. In ILC, all three CDK4/6i performed similarly; therefore, treatment selection should prioritize tolerability, manageability, drug-drug interactions, and patient preferences.

The integration of CDK4/6 inhibitors into anti-HER2 treatment strategies represents a promising approach to address the unique biology of HR + /HER2 + BC. Molecular profiling and personalized treatment strategies are essential to optimize patient outcomes and reduce unnecessary toxicity.

Bayesian network meta-analysis (NMA) was conducted to integrate direct and indirect comparisons, addressing the lack of head-to-head trials. Eleven studies (2 RCTs, 9 retrospective; 826 patients) evaluated four treatment strategies: pyrotinib + RT, pyrotinib alone, RT alone, and lapatinib + RT. In contrast, lapatinib + RT appeared to offer limited benefit and a higher risk of SAEs. Further randomized controlled trials are needed to validate these findings.
