Recently, the use of MPTXv2 has been shown to further improve the accuracy of risk stratification of ITNs.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>A total of 338 patient samples with atypia of undetermined significance (<i>n</i> = 258) or follicular neoplasm (<i>n</i> = 80) cytology diagnosis and corresponding surgical outcomes or clinical follow-up, collected between 2016 and 2020 were included [Correction added on 19 June 2024, after first online publication: In the preceding sentence, the <i>n</i> values 260 and 78 have been changed to 258 and 80, respectively.]. All samples underwent multiplatform testing (MPTXv1), which includes an oncogene panel (ThyGeNEXT<sup>®</sup>) plus a microRNA risk classifier (ThyraMIR<sup>®</sup>). A blinded, secondary analysis was performed to assess the added utility of MPTXv2 (ThyraMIR<sup>®</sup>v2). The average length of follow-up for the surveillance group (<i>n</i> = 248) was 30 months.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Sensitivity at moderate threshold was 96% and specificity at positive threshold was 99% for MPTXv2. At 14% disease prevalence, the negative predictive value at the moderate threshold was 99% and the positive predictive value at the positive threshold was 89% for MPTXv2. MPTXv2 had fewer patients classified into the moderate-risk group than MPTXv1, which was statistically significant (<i>p</i> < .001). Using surgical resection, the gold standard for outcomes, MPTXv2 showed a statistically greater area under the curve (<i>p</i> = .028) than MPTXv1, demonstrating greater accuracy for MPTXv2.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Both test versions demonstrated robust performance with low false-positive molecular results. Data suggest that incorporation of MPTXv1, and more recently MPTXv2, into clinical practice within our healthcare network resulted in improved accuracy of ITN risk stratification.</p>\u0000 </section>\u0000 </div>","PeriodicalId":9410,"journal":{"name":"Cancer Cytopathology","volume":"132 9","pages":"556-563"},"PeriodicalIF":2.6,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cncy.22829","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141179113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
