In the largest study to date of bone and soft tissue tumors, OGM detected 100% of the variants found by multiple standard techniques, including karyotyping, fluorescent in-situ hybridization (FISH) & gene fusion assays OGM was also more sensitive, including detection of diagnostic or pathogenic variants missed by karyotype in 74% (14/19) of cases that failed or were negative by karyotyping When OGM results and next-generation sequencing (NGS) results were combined, diagnostic and pathogenic structural variants (SVs), copy number variants (CNVs), and/or single nucleotide variants (SNVs) were found in ~98% of cases, a substantially greater rate than when karyotyping, FISH and NGS are used Dec. 23, 2024 -- Bionano Genomics, Inc. (Nasdaq: BNGO) today announced a publication in Modern Pathology by a group of researchers at the Johns Hopkins University School of Medicine, showing that optical genome mapping (OGM) can outperform traditional techniques in analysis of bone and soft tissue tumors. Several prior publications have shown the utility of OGM compared to traditional cytogenetics in studies of hematologic malignancies, however, data on the application of OGM in solid tumors has been relatively sparse. This study provides compelling support for extending the utility of OGM in cancer beyond hematologic malignancies to solid tumors. OGM detected all variants revealed by conventional cytogenetics: OGM showed 100% concordance, identifying all pathogenic variants detected by standard of care cytogenetic methods. The specificity of OGM was assessed to be 100%, i.e. OGM correctly identified the same pathogenic SVs and CNVs detected by standard of care/routine cytogenetics (karyotyping and FISH). OGM detected pathogenic variants missed by karyotyping: In 74% of cases with normal or failed karyotype, OGM detected diagnostic or pathogenic SVs that were missed by karyotyping. Further, in 6 cases that failed to yield any karyotyping results due to culture failure, OGM detected pathogenic SVs in all of them. Variants found by OGM but missed by standard of care included the EWSR1::ETV1 fusion, which is a key molecular hallmark of clear cell sarcoma and helps to differentiate it from other soft tissue sarcomas and melanomas. OGM resolved complex cancer genomes: Study authors found that OGM data could re-characterized and better defined complex structural rearrangements including chromoanagenesis in 27% of cases and complex 3-6-way translocations in 15% of cases when compared to traditional cytogenetic methods. OGM combined with NGS found pathogenic variants in 98% of cases, a substantially greater rate than when karyotyping, FISH and NGS are used: The integrated approach of the combination of OGM and NGS resulted in the detection of pathogenic SVs and sequence variants in ~98% of cases. OGM was 100% concordant with NGS for aneuploidy detection. OGM findings have the potential to qualify subjects for targeted therapies that otherwise would not have been possible: The authors state that several of the OGM findings could result in the potential for these cases to qualify for either targeted treatments or clinical trials. For example, cases with potential to be treated by CDK4/6 inhibitors (palbociclib, ribociclib, abemaciclib), TRK inhibitors (larotrectinib, entrectinib), pan-FGFR inhibitors (erdafitinib or futibatinib) were highlighted. Erik Holmlin, president and chief executive officer of Bionano commented, “Approximately 50% of bone and soft tissue tumor samples fail to reveal actionable information for proper classification of disease, prognosis and therapeutic management because they either fail to culture or because traditional techniques in cytogenetics lack adequate sensitivity and specificity to reliably detect relevant variants. We have seen increasing evidence for OGM as a valuable alternative to cytogenetic methods in blood cancers, and we are thrilled to see researchers at Johns Hopkins publishing this compelling case for extending OGM’s utility to bone and soft tissue tumors.” The full research publication is available at: https://doi-org.libproxy1.nus.edu.sg/10.1016/j.modpat.2024.100684 Bionano is a provider of genome analysis solutions that can enable researchers and clinicians to reveal answers to challenging questions in biology and medicine.
