    Biphasic (squamoid) papillary renal cell carcinoma: a distinct molecular and morphologic subtype within the PRCC spectrum. (PubMed, Virchows Arch)
    Targeted NGS revealed MET amplification (2 cases), MET mutation (1 case), NOTCH1 mutations (9 cases), and alterations in MAP2K2, FGFR4, DDR pathway genes (e.g., PMS2, CDK12R44W, RAD51C/D), and chromatin remodeling genes (EZH2, ARID1A). These findings support BPRCC as a distinct subtype of papillary RCC with consistent biphasic morphology, immunophenotypic divergence, and a unique molecular profile enriched for NOTCH, MAPK, and DDR pathway alterations.

    A novel ddPCR assay for BRCA1 and RAD51C methylation: Advancing HRD Detection in Ovarian Cancer. (PubMed, J Mol Diagn)
    ddPCR effectively identified methylation-driven HRD, explaining deficiency in 36.4% additional patients with a positive GII score. These findings highlight the importance of incorporating methylation analysis into HRD testing to improve patient stratification for PARP inhibitor therapy.

    Predictive value of homologous recombination-related gene mutations in survival outcomes of first-line nivolumab plus chemotherapy for gastric cancer. (PubMed, Gastric Cancer)
    HRR mutations were associated with favorable survival outcomes in patients treated with nivolumab plus chemotherapy. Our findings suggest that HRR mutations may serve as a potential predictive biomarker for first-line ICI-based chemotherapy in gastric cancer.
