BRD8 regulated ER-dependent and independent growth pathways, and depletion of BRD8 abolished neratinib-induced ER activation and restored drug sensitivity in resistant cells. A 3-gene BRD8 signature successfully predicted anti-HER2 therapy response in two human clinical trials. Together, these findings establish BRD8 as both a predictive biomarker for anti-HER2 response and a therapeutic target to overcome resistance in HR+/HER2+ breast cancer.

The updated analysis of the phase 3 PHILA trial confirmed the superiority of pyrotinib in combination with trastuzumab and docetaxel over placebo in combination with trastuzumab and docetaxel in sustaining longer progression-free survival and improving overall survival for initial treatment of HER2 positive metastatic breast cancer. The safety profile remained consistent with interim findings, with no new safety signals identified during extended follow-up. This analysis reinforces the efficacy of this dual anti-HER2 (pyrotinib plus trastuzumab) regimen as an effective treatment strategy for this patient population.

Two metastatic SDC patients with HER2 amplification responded to HER2 tyrosine kinase inhibitor (TKI) pyrotinib and the combination of trastuzumab and pertuzumab, respectively. Our work underscores the potential of genomic profiling to guide precision therapy in SDC, with HER2-targeted treatments offering promising therapeutic avenues.

The present study revealed five prognostic genes and constructed a predictive model, which provided a theoretical basis for the correlation linking Tolerogenic dendritic cells to gastric cancer, and established potential therapeutic strategies in managing gastric cancer. Single-cell analysis revealed that INHBA, ASCL2, and CD36 exhibited marked differential expression in dendritic cells.

Moreover, its ability to traverse the blood-brain barrier confers potential therapeutic advantages in patients with brain metastases. This comprehensive review provides a systematic overview of the pharmacological profile and mechanism of action of pyrotinib, with emphasis on recent clinical trials assessing pyrotinib-based regimens in HER2-positive breast cancer.

No new safety concerns were found. This study provides real-world evidence of the effectiveness and safety of afatinib as first-line therapy for Chinese patients with EGFR mutation-positive advanced NSCLC.

Among older adults, 31 (97%) patients experienced AEs of all grades, and only six patients had grade ≥ 3 AEs with no grade 5 AEs. Afatinib demonstrated comparable therapeutic efficacy and safety in older and non-older adult patients with advanced EGFR-mutant NSCLC.Trial registration: UMIN-CTR identifier (UMIN000024935).
