Combining eprenetapopt with carboplatin shows promising preclinical efficacy by enhancing cytotoxicity in olaparib-resistant models and demonstrating synergistic interaction; these data support the combination as a potential strategy to mitigate PARPi resistance and carboplatin cross-resistance in TP53 mutant HGSOC and TNBC cell lines. Although further studies are needed to elucidate the molecular mechanisms underlying the synergistic effect, here we point out the combination of eprenetapopt and carboplatin as a potential therapeutic strategy to address olaparib resistance in HGSOC and TNBC patients.

Participants desired more follow-up, better support and education around practical and emotional considerations for prophylactic surgery, and acknowledgment of personal and community factors that impacted them. Genetic counselors can personalize each visit to the patient and their needs by extensively contracting and bringing up topics that may be relevant and adjusting based on their preferences and values.

<br><br><b></b> This study delineated the mutational spectrum of recurrent and/or metastatic SDC. Even in advanced disease, prognostically relevant mutations were identified, emphasizing the clinical importance of cancer genomic profiling tests.

This work lays the basis for precision and personalised treatment for TNBC patients. However, future optimisation and clinical validation of these nanoparticles can be done in future to determine their translational potential for use in practice.

Actionable genomic mutations such as PIK3CA, ESR1, ERBB2, BRCA1/2, and AKT/PTEN are reviewed in relation to their corresponding therapeutic agents. Implementation challenges, pre-analysis pitfalls, uncertain sampling cadence, cost barriers, and disparities in access are discussed, along with potential solutions.

In parallel, circulating cell-free DNA fragments containing Alu sequences have also been correlated with delivered radiation dose and clinical toxicity, underscoring their potential as minimally invasive biomarkers. Taken together, these findings position Alu activation as both a mechanistic driver of radio-response heterogeneity and a minimally invasive biomarker for biodosimetry and toxicity risk stratification.

This report highlights an extremely rare, pathologically confirmed case of synchronous bilateral primary breast carcinoma with OCGCs. The presence of OCGCs in both invasive and in situ components suggests that their formation can be induced at early stages of tumor development, likely reflecting a distinct immune-reactive tumor microenvironment driven by host-related factors.

However, many patients with these variants have urothelial cancer of the bladder only. Broader genetic testing, particularly in those with a suggestive personal or family cancer history, may help identify patients at risk who might otherwise be missed.
