Capivasertib, an AKT inhibitor, approved in combination with fulvestrant for hormone receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer with ≥1 PIK3CA, AKT1, and/or PTEN alterations, significantly improved progression-free survival in the CAPItello-291 phase 3 trial. However, capivasertib-associated adverse events of diarrhea, rash, and hyperglycemia may require proactive management. This article provides practical recommendations to support prevention and early intervention to optimize adherence and treatment outcomes.

Trastuzumab-based therapy has shown survival benefit in HER2-positive SEC, leading to its inclusion in current treatment guidelines...The prognostic value remains debated, though recent trials of antibody-drug conjugates (e.g., T-DXd) show promise...Diagnostic challenges include variable scoring systems, intratumoral heterogeneity, and HER2-low classification. Standardization of testing criteria and further clinical validation of HER2-targeted strategies across gynecologic tumors are essential to guide personalized therapy and improve outcomes.

The pattern of metastatic spread, particularly lymphatic involvement, appears to influence the efficacy of nivolumab in advanced or recurrent gastric cancer. Recognizing metastatic patterns may assist in optimizing patient selection and therapeutic strategies for immune checkpoint blockade.

Hb 100 ng/mL, height >160 cm, and the presence of lymph node metastases were associated with HER2 expression and positivity. HER2 testing should be considered mandatory when all these factors are present. The mechanisms linking these four factors to HER2 expression require further investigation.

This trial has been approved by the Institutional Review Board (IRB) and began patient enrollment in January 2024. The trial will provide insights into the safety and effectiveness of a novel combinatorial therapy for BCBM.

While challenges remain in distinguishing Luminal B2, the use of BT imaging and AI demonstrates promise for refining molecular subtype assessment and improving clinical decision-making.Clinical Relevance-This study demonstrates that AI-driven analysis of digital breast tomosynthesis can capture tumor and microenvironment characteristics, providing valuable insights into disease staging and progression. By leveraging comprehensive imaging data rather than limited biopsy samples, this approach has the potential to improve non-invasive molecular subtyping, aiding personalized treatment decisions while reducing reliance on invasive procedures.

Combining palbociclib, trastuzumab, and ET was safe and improved significantly PFS, compared to TPC in previously treated HER2-positive, PAM50 luminal A/B ABC patients.

The efficacy of NAT regimens containing trastuzumab plus pertuzumab (HP) and trastuzumab plus pyrotinib (HPy) was compared. Both HP and HPy combined with chemotherapy can be considered as optional NAT regimens for HER2-positive BC. The nomogram incorporating common clinical indicators provides a basis for clinicians to predict NAT efficacy at an earlier stage.

Collectively, our study demonstrates that ITPC exhibits a robust accuracy for detecting SLN metastases in cN + breast cancer patients treated with NAC. The findings support the implementation of molecular subtype-specific SLN management: ITPC alone may be adequate for HER2-positive and TNBC tumors; for hormone receptor-positive (Luminal) subtypes, ITPC may need to be combined with molecular/immunohistochemical analysis.

The treatment resulted in a complete response, with a tolerable side effect profile and ongoing treatment-free survival. Our case adds to the literature suggesting clinical benefit of the use of Trastuzumab-deruxtecan in HER2-positive tumors, and underscores the importance of molecular testing for patients with rare tumor subtypes.

Elevation of serum BNP could not predict cardiotoxicity. Less frequent LVEF monitoring could be considered during long-term use of trastuzumab.
