Living guidelines, continuously updated frameworks based on emerging data, are essential to bridge this gap. They enable just-in-time incorporation of new therapies, streamline biomarker-driven care, and address the unique needs of rare and ultrarare cancers. Regulatory approvals for tumor-agnostic agents, such as NTRK inhibitors and immunotherapies for microsatellite instability-high/mismatch repair-deficient tumors, underscore the urgency for unified guidance. Trials like TAPUR, TRACK, and NCI-MATCH demonstrate the feasibility and benefit of molecular profiling across diverse cancer types. Tools like ESMO's ETAC-S provide structured criteria for evaluating tumor-agnostic potential, yet real-world implementation lags. Living guidelines can harmonize testing practices, improve access, and educate clinicians on cross-tumor applicability. They also facilitate proactive biomarker testing, reduce treatment delays, and enhance patient safety through tailored toxicity management.

Isolated cases with extreme early-onset or multiple unrelated cancers are rare and frequently underdiagnosed. This study aimed to improve genetic diagnostic yield in unresolved patients with strong clinical suspicion of hereditary cancer. Inclusion criteria were (1) ≥4 primary tumors in different organs (or ≥3 if two are rare), (2) adult-type cancers at ≤25 years, or (3) profuse gastrointestinal adenomatous polyposis before age 50 years or profuse polyposis of unknown type before age 30 years.</p><p><strong>Methods: </strong>Germline DNA from 98 patients selected through ERN-GENTURIS underwent short-read whole-genome sequencing (WGS). Ninety had received negative results from standard genetic testing, whereas eight had not been tested. Variant analysis was performed using the RD-Connect GPAP and Solve-RD frameworks.</p><p><strong>Results: </strong>Pathogenic or likely pathogenic variants in phenotype-related high-penetrance genes were found in 6% of patients, including <i>APC</i> and <i>TP53</i> mosaicisms and germline variants in <i>TP53</i>, <i>BAP1</i>, <i>BARD1</i>, and <i>MBD4</i> (homozygous). Three patients carried pathogenic variants in hereditary cancer genes unrelated to their phenotype, and a heterozygous <i>ERCC3</i> pathogenic variant was detected in a young patient with breast cancer. Suggestive variants of uncertain significance were identified, including a chromosome 3 inversion affecting <i>VHL</i> and <i>MLH1</i> in a patient with renal and gastric cancers. Potentially regulatory noncoding variants in phenotype-associated genes were observed in 15% of patients (22 variants).</p><p><strong>Conclusion: </strong>Comprehensive resequencing of patients suspected of hereditary cancer increased the diagnostic yield by 6%. Detected pathogenic variants involved phenotype-related genes not previously analyzed or missed because of mosaicism. WGS further enables identification of novel gene associations and structural, deep intronic, or regulatory variants.</p>","PeriodicalId":14797,"journal":{"name":"JCO precision oncology","volume":"10 4","pages":"e2500354"},"PeriodicalIF":5.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13098671/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147698371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
