This approach offers a promising, non-invasive alternative to traditional tissue sampling by enabling a "digital biopsy." Integrating these models into clinical workflows could reduce the diagnostic burden on patients and facilitate personalized treatment planning. However, further validation in larger, prospective cohorts is necessary.

Comprehensive CYP2D6 profiling improves phenotype assignment and highlights methodological pitfalls that may contribute to inconsistencies in pharmacogenetic studies. While no definitive association with clinical outcomes was observed in the overall cohort, these findings underscore the importance of analytically robust genotyping strategies and warrant validation in larger, prospectively designed cohorts, and highlight the importance of comprehensive genotyping strategies in resolving inconsistencies across pharmacogenetic studies.

Thus, VALD-3 treatment initiated the ROS/JNK/Bax-mitochondrial apoptosis pathway, leading to caspase-3 activation and GSDME cleavage, thereby executing pyroptosis. These findings suggest that GSDME-dependent pyroptosis is a novel mechanism by which VALD-3 eradicates cancer cells and offer new insights into potential clinical applications for anticancer therapies.

Available breast cancer-specific data are largely retrospective and suggest clinically meaningful but attenuated weight loss compared with pivotal obesity trials, with concurrent aromatase inhibitor or tamoxifen use associated with smaller reductions...Studies also suggest potential survivorship benefits relevant to lymphedema and cardio-oncology, although causality is unproven. Prospective cancer-specific trials and implementation studies are needed to define safety; optimal timing; patient selection; and effects on oncologic outcomes, function, and quality of life.

We discuss the case literature on the management of ophthalmic and eyelid metastases, including the role of radiotherapy. We outline the multi-disciplinary team (MDT) discussions and recommendations made in the present case, which ultimately found that the risks of radiation toxicity would outweigh the benefits. Adjuvant therapy with fulvestrant and palbociclib was recommended, with future consideration of a CDK 4/6 inhibitor in the event of metastatic recurrence.

TARGIT-IORT is associated with excellent local control, very high survival rates, and a very low toxicity profile for low-risk early breast cancer, consistent with the TARGIT-A trial and should be offered to patients when suitable.

Commercially representative vepdegestrant tablets demonstrated bioequivalence with the pivotal phase 3 vepdegestrant tablets; all tablet formulations of vepdegestrant 200 mg were well tolerated.

Real-world data demonstrate that ODRS correlates with key pathological characteristics and can guide adjuvant therapy selection, independent of menopausal status or nodal involvement. This suggests that ODRS is useful in tailoring chemotherapy decisions in ER-positive/HER2-negative breast cancer.

Cells were characterized for dormancy- like behavior using increased p-p38 and decreased p-ERK expression (dormant, p-p38High and p-ERKLow expression), reduced Ki67 expression, elevated p21 and p27 levels by immunofluorescence, absence of senescence using β-galactosidase staining and resistance to doxorubicin...FGF-2 was required with laminin to induce dormancy in MDA-MB-231 cells under hypoxic conditions (FGF-2 plus fibronectin were unable to induce dormancy), whereas laminin or fibronectin alone were sufficient under normoxic conditions. Overall, we established culture conditions that recapitulate an in vitro breast cancer dormancy-like phenotype and reveal subtype-specific differences in dormancy regulation.

High-resolution lineage tracing and multi-omic studies demonstrate that CDK4/6i resistance is shaped by clonal selection and adaptive remodeling of cell states, with the ESR1 mutation status and the specific inhibitor acting as key determinants of evolutionary trajectories. These findings suggest that both variables should be considered when designing sequential and combination treatment strategies to overcome CDK4/6i resistance.
