Second hits were confirmed in genes with (NF1, RB1, TP53, EXT2, and SDHC) and without (ATM, CDC73, MLH1, MSH6, POLG, and KCNQ1) known association with mesenchymal tumor predisposition. Sarcomas from two Lynch syndrome patients showed mismatch repair deficiency, predicting a treatment response to immune checkpoint inhibitors (Level 1 biomarker according to the FDA (Federal Drug Administration) and ESMO (European Society for Medical Oncology)). None of the three CHEK2 carriers had a second hit in the tumor, suggesting a weak link to sarcoma.\n\nWe conclude that second-hit analyses can be used in standard of care to identify syndrome-related tumors. This approach can help distinguish true manifestations of tumor syndromes from unrelated germline findings and enhance the understanding of germline predisposition in soft tissue tumors. Prospective screening using germline whole genome sequencing should be considered when comprehensive somatic sequencing is introduced into clinical practice.", "doi": "10.3390/cancers16223816", "pmid": "39594770", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC11592761"}, {"db": "pii", "key": "cancers16223816"}], "notes": [], "created": "2026-09-23T13:18:05.961Z", "modified": "2026-09-23T13:18:06.015Z"}, {"entity": "publication", "iuid": "4f306abf9d6a4413a37d3c05184c8591", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/4f306abf9d6a4413a37d3c05184c8591.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/4f306abf9d6a4413a37d3c05184c8591"}}, "title": "Comprehensive Genomic Profiling Alters Clinical Diagnoses in a Significant Fraction of Tumors Suspicious of Sarcoma.", "authors": [{"family": "\u00d6fverholm", "given": "Ingegerd", "initials": "I", "orcid": "0000-0002-6907-8004", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/7f20e1dcc8044bd59e46e6e621970946.json"}}, {"family": "Wallander", "given": "Karin", "initials": "K", "orcid": "0000-0001-8166-9678", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/2d3f581341864b9696eb87f2eb139335.json"}}, {"family": "Haglund", "given": "Cecilia", "initials": "C", "orcid": "0000-0001-5484-8945", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/feaf6e6ac6124010879296805aefa71f.json"}}, {"family": "Chellappa", "given": "Venkatesh", "initials": "V", "orcid": "0000-0003-1431-6949", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/2a6df7e52f9c4dc198f775dd68418bf4.json"}}, {"family": "Wejde", "given": "Johan", "initials": "J", "orcid": "0009-0009-1563-8158", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/779fda01cb5c48bb9298cf4b58832b5b.json"}}, {"family": "Gellerbring", "given": "Anna", "initials": "A", "orcid": "0009-0002-4505-2173", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/f976bcaf72cc4dff82337be3b0f4406a.json"}}, {"family": "Wirta", "given": "Valtteri", "initials": "V", "orcid": "0000-0003-3811-5439", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/6a4f538e838c483eb968174f2df89165.json"}}, {"family": "Renevey", "given": "Annick", "initials": "A", "orcid": "0000-0001-7411-6063", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/67d697726ce24c9aa520c2f939fe0b9c.json"}}, {"family": "Caceres", "given": "Eva", "initials": "E", "orcid": "0000-0003-2890-2631", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/4a1a215e82844e94b0dae86bd0694118.json"}}, {"family": "Tsagkozis", "given": "Panagiotis", "initials": "P", "orcid": "0000-0002-6631-2053", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/cb8bbbcf790c480287e6db74ecaba104.json"}}, {"family": "Mayrhofer", "given": "Markus", "initials": "M", "orcid": "0000-0003-3403-0083", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/94acf55356df407299eb37645fbfa066.json"}}, {"family": "Papakonstantinou", "given": "Andri", "initials": "A", "orcid": "0000-0002-4232-4658", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/92ce7841d57444208c3d0827c5b59f68.json"}}, {"family": "Linder-Stragliotto", "given": "Christina", "initials": "C", "orcid": "0009-0002-1247-7028", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/9845c43d1a354904a285d8947f4c0d4d.json"}}, {"family": "Br\u00e4nstr\u00f6m", "given": "Robert", "initials": "R", "orcid": "0000-0001-6245-7223", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/3226406376a0446a862fee2823bbf447.json"}}, {"family": "Larsson", "given": "Olle", "initials": "O", "orcid": "0000-0001-8173-2956", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/065233fb84e54ac4b9dfe4aebc8f7b2a.json"}}, {"family": "Lindberg", "given": "Johan", "initials": "J", "orcid": "0000-0003-3610-6774", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/e5102a5c0ee2436bb9f35d36188d3e69.json"}}, {"family": "Lin", "given": "Yingbo", "initials": "Y", "orcid": "0000-0001-7190-2261", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/abe61b8bfc9d4adbab3c83762278c3c0.json"}}, {"family": "Haglund de Flon", "given": "Felix", "initials": "F", "orcid": "0000-0002-7015-3841", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/be9b0eda414549868536c4e96a3a845a.json"}}], "type": "journal article", "published": "2024-06-14", "journal": {"title": "Clin.

For soft-tissue and bone tumors, this classification is currently based primarily on morphology assessment and IHC staining. However, these standard-of-care methods can pose challenges for pathologists. We therefore assessed how whole-genome and whole-transcriptome sequencing (WGTS) impacted tumor classification and clinical management when interpreted together with histomorphology.\n\nWe prospectively evaluated WGTS in routine diagnostics of 200 soft-tissue and bone tumors suspicious for malignancy, including DNA and RNA isolation from the tumor, and DNA isolation from a peripheral blood sample or any non-tumor tissue.\n\nOn the basis of specific genomic alterations or absence of presumed findings, WGTS resulted in reclassification of 7% (13/197) of the histopathologic diagnoses. Four cases were downgraded from low-grade sarcomas to benign lesions, and two cases were reclassified as metastatic malignant melanomas. Fusion genes associated with specific tumor entities were found in 30 samples. For malignant soft-tissue and bone tumors, we identified treatment relevant variants in 15% of cases. Germline pathogenic variants associated with a hereditary cancer syndrome were found in 22 participants (11%).\n\nWGTS provides an important dimension of data that aids in the classification of soft-tissue and bone tumors, correcting a significant fraction of clinical diagnoses, and identifies molecular targets relevant for precision medicine.
