    Integrated Liquid Biopsy and Tumor Tissue Genomic Profiling of Appendiceal Cancer: cfDNA Burden, Mutation Landscapes, and Clinical Outcomes. (PubMed, Ann Surg Oncol)
    This study supports integrating comprehensive ctDNA assays into standard diagnostic and treatment pathways for AC using large gene panels. TP53, SMAD4, SPTA1, and GNAS mutations serve as prospective tumor-specific molecular classifiers for histological grade, while germline variants in NOTCH4 and BARD1 may further influence disease biology, with ZFHX3, ADGRA2, POLE, and TCF3 affecting grade stratification. Overall cfDNA concentration may serve as a potential prognostic biomarker in AC.

    Integrating breast tumour homologous recombination deficiency status to aid germline BRCA1 and BRCA2 variant classification. (PubMed, EBioMedicine)
    Analysis across multiple tumour whole-genome sequencing datasets has shown that HR status prediction algorithms can separate profiles for BRCA1 and BRCA2 pathogenic variants and provide further evidence at increased weight to aid in the classification of germline BRCA1 and BRCA2 variants. Tumour sequencing offers a promising strategy for reducing the uncertainty in germline variant interpretation.

    BPHL promotes TNBC stemness by resolving R-loops via POLR2A lactylation inhibition and BARD1-mediated ubiquitination. (PubMed, Cancer Lett)
    Intriguingly, in vivo BPHL depletion curbed tumorigenesis-an effect partially mitigated by RNase H overexpression but reinstated by β-catenin blockade. These insights position BPHL as a compelling target for eradicating TNBC CSCs.

    The Contribution of Genetic Modifiers to Ovarian Cancer Risk in BRCA1 and BRCA2 Pathogenic Variant Carriers. (PubMed, Cancers (Basel))
    The analysis identified 11 variants affecting both BRCA1 and BRCA2 carriers, most of which increase risk, including the following: IRS1, RSPO1, SYNPO2, BABAM1, MRPL34, PLEKHM1, and TIPARP...The only SNP reaching genome-wide significance (p < 5 × 10-8) was in BNC2. The article summarizes the growing number of genetic modifiers of ovarian cancer risk among BRCA1/2 carriers and highlights their potential to improve individualized risk assessment, enhance patient stratification, support personalized prevention and surveillance strategies, deepen the understanding of disease biology, and identify potential therapeutic targets.

    Tyrer-Cuzick Lifetime Risk Is Not Associated With Non-BRCA1/2 Pathogenic Variants for Breast Carcinoma. (PubMed, Breast J)
    When choosing a genetic testing panel for breast cancer genes, TC is not as a reliable predictor on individual patient's family history, NCCN guidelines, or ASBrS guidelines. Our study supports the need to develop a genetic risk calculator that incorporates the predictive value for these non-BRCA1/2 PVs in otherwise low or average TC women.
