    Beyond HRD status: Unraveling Genetic Variants Impacting PARP Inhibitor Sensitivity in Advanced Ovarian Cancer. (PubMed, Cancer Res Commun)
    P2; Additionally, analysis of BRCA1 variants revealed that truncating variants in exon 11 correlated with clinical benefit when niraparib was combined with bevacizumab. Conclusively, our findings highlight the complexity of PARPi response in AOC and underscore the importance of exploring somatic variants beyond HRD status. Further investigation into exon 11 variants of BRCA1 and the potential of combination treatment is warranted.

    Mismatch Repair (MMR) and Homologous Recombination (HR) Deficiency: Real-Life Applications of biomarkers for complementary approaches in Epithelial Ovarian Cancer (AIOM 2024)
    HRD genomic instability tests and multigene panel assessments serve as synergistic tools in EOC clinical settings, proving essential for identifying patients likely to benefit from PARPi therapy. These tools also enhance the detection of HRR and MMR gene variants, aiding in preventive care. Further investigations into the genetic profiles of HRD-negative tumors are crucial for advancing cancer risk management and developing novel therapeutic avenues.

    In-House Testing for Homologous Recombination Deficiency (HRD) in Mexican Patients with High-Grade Serous Ovarian Cancer (AMP Europe 2024)
    In our preliminary validation cohor t, we observed a 90% concordance rate between assays, consistent with the results of other series (81.6% to 87.8%). When applying the AmoyDX HRD focus panel in HGSOC, we detected HRD positivity in 48.22% of tumors, similar with the incidences reported in PAOLA1 (48%), PRIMA (50.9%), and VELIA (50.1%) trials. While the global prevalence of BRCA1/2 alterations in ovarian cancer ranges from 20% to 25%, we found that 32% of positive cases in our series exhibited gene variants consistent with previous reports of BRCA variant frequencies in Mexican patients.

    Real-life data for HRD testing from the only French platform using the Myriad MyChoice test (ESMO-GC 2024)
    Background: HRD is correlated with increased survival of patients with advanced ovarian cancer treated with maintenance olaparib + bevacizumab. The Myriad MyChoice test allows the analysis of BRCA variations and the GIS at the same time for a complete and faster molecular diagnosis, which is suitable for the majority of patients. Moreover, the thorough quality selection of tissue samples during the bioinformatics analysis leads to a strong reliability and a confidence in the results by dramatically reducing the rate of false negative results.

    Feasibility and cost-effectiveness of genetic counselling for all patients with newly diagnosed ovarian cancer: a single-centre retrospective study. (PubMed)
    Using genetic counselling to consent patients with newly diagnosed ovarian cancer for germline testing fulfils the international gold standard. Subsequent somatic homologous recombination deficiency analysis complements testing and identifies more patients who will benefit from PARP inhibitor maintenance therapy. Contrary to previous health cost model studies, the procedure does not increase testing costs in the Swiss population and does not delay maintenance therapy. Therefore, all patients should be offered a primary germline analysis. The challenge for the future will be to ensure sufficient resources for prompt genetic counselling and germline testing.

    Olaparib Addition to Maintenance Bevacizumab Therapy in Ovarian Carcinoma With BRCA-Like Genomic Aberrations. (PubMed, JAMA Netw Open)
    In this secondary analysis of the PAOLA-1 randomized clinical trial, patients with a BRCA-like tumor, but not those with a non-BRCA-like tumor, had a significantly longer survival after olaparib plus bevacizumab treatment than placebo plus bevacizumab treatment. Thus, the BRCA1-like classifier could be used as a biomarker for olaparib plus bevacizumab as a maintenance treatment.

    Implementing MyChoice® CDx HRD testing for the Nordics: lessons from 2021 to 2023. (PubMed, Acta Oncol)
    The myChoice® CDx Nordic core facility has been well received among the Nordic countries and provides new insights on the influence of national guidelines on HRD testing. Overall, we experienced an efficient turnaround time and a high fraction of conclusive results. Interestingly, prior somatic BRCA testing is redundant when assessing HRD status through myChoice® CDx test since somatic BRCA screening is already a significant component of the myChoice® CDx test. Thus, it should be considered to omit prior somatic BRCA testing to ensure a rationalised HRD diagnostic flow optimised for clinical use.

    Homologous Recombinant Deficiency Does Not Share Morphologic Surrogates of BRCA-mutated High-Grade Serous Carcinoma (USCAP 2024)
    BRCA mutation is one cause of HRD and appears that SET morphology associated with HGSC is unique to BRCA-mutation and not under the umbrella of other causes and effects of HRD. HRD in HGSC may produce its own molecular surrogate that is yet to be discovered. Definitive determination of which platform is superior for clinical validation of HRD assessment as a surrogate to Myriad MyChoiceDX gold standard requires matched analysis against Myriad and patient's progression free survival.

    In patients with advanced ovarian cancer who are BRCA WT, HRD does not seem to predict cytoreductive surgical outcome or pre-treatment disease volume, although patients with HRI were less likely to be offered PCS. Larger, prospective cohort with HR status on all comers with HGSOC, will help to determine the significance of HR status when deciding on PCS or ICS.

    Multi-gene NGS tumour testing was capable of identifying all clinically relevant germline variants. Although paired multi-gene tumour-germline testing is required to determine variant origin, over 40% of individuals in this study could have avoided germline testing following negative tumour results. These results suggest that streamlining genetic testing for EOC patients via primary multi-gene tumour testing is possible with further investigation.

    Homologous Recombination Deficiency (HRD) In Primary Advanced Stage And Recurrent P53 Abnormal Endometrial Carcinoma (ESGO 2024)
    Further investigation of HRD and EC-specific GIS cut-off value are highly warranted and may help to improve outcome in this specific EC subgroup. Patients with p53abn tumors may benefit from PARP inhibition and HRD testing may provide key information for patient selection.

    Real-World Concordance between Germline and Tumour BRCA1/2 Status in Epithelial Ovarian Cancer. (PubMed)
    The myChoice CDx was able to detect most germline BRCA1/2 pathogenic variants in tumour DNA, although a proportion of pathogenic large rearrangements were not reported. If Myriad's myChoice CDx is used for tumour BRCA1/2 testing, our data supports a testing strategy of germline and tumour BRCA1/2 testing in all patients diagnosed with epithelial ovarian cancer aged < 79 years old, with germline BRCA1/2 testing only necessary for patients aged ≥ 80 years old with a tumour BRCA1/2 pathogenic variant.

    Tumour-based Mutational Profiles Predict Visceral Metastasis Outcome and Early Death in Prostate Cancer Patients. (PubMed, Eur Urol Oncol)
    Mutations in the TP53 gene and genes (APC/CTNNB1) related to the Wnt pathway are associated with metastatic visceral dissemination and early death. These genomic alterations could be considered as markers to identify prostate cancer patients at a high risk of life-threatening disease who might benefit from more intensified treatment or new targeted therapies.

    Repair-assisted damage detection as a potential predictive biomarker for immunotherapy response in ovarian cancer (SGO 2024)
    RADD demonstrates the ability to determine a quantitative analysis of DNA damage and repair in ovarian cancer samples. Considering its rapid turnaround time and correlation with HR status, RADD has potential use in determining clinical trial candidates stratified by HR status. Additionally, RADD correlates with known predictive biomarker CD39 for response with immunotherapy.
