No first-line regimen significantly improved OS or PFS in HER2-positive advanced gastric cancer. However, HLX22-based and immune-combination strategies show potential clinical value-particularly in enhancing ORR-and merit further investigation.

OFS + AI were associated with better DDFS in patients with RD after neoadjuvant therapy. Our findings can assist shared decision-making on adjuvant endocrine therapy of these patients.

In vitro mechanistic studies revealed that CPT1A may promote mitochondrial damage and induce cardiomyocyte injury by interacting with Parkin. This study underscores the utility of multi-omics integration in elucidating TIC mechanisms and paves the way for personalized cardioprotective strategies in HER2-targeted therapy.

DS extract alleviates TRZ-induced cardiotoxicity, manifested by improved cardiac function, reduced myocardial injury markers, and mitigated tissue and mitochondrial damage. Its mechanism of action is associated with regulating proteins in the ferroptosis pathway (upregulating GPX4 and downregulating ACSL4). Additionally, tanshinone I, IIA, and IIB have been identified as potential active components.

In esophageal tumors, adjuvant nivolumab is used. Among HER2-positive patients, adding pembrolizumab to trastuzumab and chemotherapy - in PDL1 CPS ≥1 cases - has become a new standard. A special mention must be made of MSI-H tumors, in which immunotherapy is highly effective, and adjuvant chemotherapy is not recommended according to current guidelines.

We show that Tucatinib potently inhibits the proliferation and migration of cervical tumor cells in vitro and tumor growth in a mouse xenograft model, while exhibiting excellent biological safety. These findings offer molecular insights into the structural and functional mechanism of MCT2 and identify Tucatinib as novel dual inhibitor of both transporters.

Furthermore, treatment with sunvozertinib did not change protein expression or subcellular localization of ABCB1. Altogether, these data demonstrate that sunvozertinib, when combined with other conventional chemotherapeutic agents, can overcome MDR and improve therapeutic effect.

In the context of PTEN loss and AR inhibitor resistance, zenocutuzumab did not restore sensitivity. These findings highlight the critical molecular context in which tumor microenvironment (TME)-derived NRG1 impacts responsiveness to AR inhibition and suggest that targeting NRG1 is a promising strategy for overcoming resistance to androgen blockade in PTEN-wildtype prostate cancers.

Pyrotinib showed good antitumor activity in the treatment of patients with HER2-positive advanced breast cancer and displayed a degree of efficacy in patients with brain metastases. The main adverse reaction was diarrhea, which was mostly low to moderate in severity, and the incidence of high-grade AEs was generally low, with controllable toxicity.

All enrolled patients received the full treatment protocol consisting of anthracycline followed by 12 months of trastuzumab alone or with pertuzumab. The highest risk was observed when both elevated hs-Tn I (≥82 ng/L after four cycles of anti-HER2 agents) and elevated hs-CRP (after four cycles of anthracyclines) were present. The interaction between both hs-Tn I and hs-CRP demonstrates significant predictive value for cardiotoxicity risk related to HER2+ breast cancer treatment.

P2, N=13, Terminated, Spanish Breast Cancer Research Group | Trial completion date: Aug 2026 --> May 2025 | Active, not recruiting --> Terminated | Trial primary completion date: Aug 2026 --> May 2025; The study was closed early due to safety concerns and an unfavorable benefit-risk balance. Unexpected high neutropenia rates required a costly sub-study, which was not feasible, forcing the sponsor to terminate the trial prematurely.
