A Delphi method was used, consisting of 4 rounds of voting and subsequent discussions. The panel included 18 international experts from 11 countries and 4 continents. Consensus was defined as ≥75% agreement among participants. Recommendations were structured into the following categories: thromboprophylaxis, perioperative management, and VTE treatment. Consensus was reached on several critical areas, resulting in 14 recommendations. Key recommendations include: thromboprophylaxis should be considered at time of CS diagnosis and continued for 3 months after biochemical remission, provided there are no obvious contraindications. The standard weight-based prophylactic dose of low molecular-weight heparin is the preferred agent for thromboprophylaxis in patients with CS. Additionally, perioperatively and around inferior petrosal sinus sampling, thromboprophylaxis should be reconsidered if not already initiated at diagnosis. For VTE treatment, extended thromboprophylaxis is advised continuing for 3 months after Cushing is resolved. These Delphi consensus-based recommendations aim to standardize care practices and enhance patient outcomes in CS by providing guidance on thromboprophylaxis, including its initiation and continuation across various disease states, as well as the preferred agents to use. The panel also highlighted key areas for further research, particularly regarding the use of direct oral anticoagulants in CS and the management of mild CS and mild autonomous cortisol secretion.

Additionally, we developed a support vector machine model for diagnosing malignant and high-risk PTCs.</p><p><strong>Results: </strong>CLDN16 demonstrated high specificity for PTC, with positive detection rates (88.0% in The Cancer Genome Atlas [TCGA] and 88.3% in our center) significantly surpassing BRAF-V600E (47.5% in TCGA and 74.3% in our center). This resulted in superior diagnostic accuracy (ROC-CLDN16 = 0.922 vs ROC-BRAF-V600E = 0.742 in TCGA). CLDN16 exhibited stable expression across primary and metastatic sites and was associated with aggressive features, including extrathyroidal extension and lymph node metastasis. CLDN16 knockdown inhibited migration, invasion, and iodine uptake in PTC cells. Clinically, CLDN16 effectively identified malignancy in BRAF wild patients (94.2%), and combined with BRAF-V600E, achieved 96.9% accuracy. The incorporation of CLDN16 into PTC molecular typing facilitated precise high-risk identification (92.0% accuracy in the training set and 100% in the validation set).</p><p><strong>Conclusions: </strong>CLDN16 presents a promising biomarker that could surpass BRAF-V600E, offering effective clinical utility and revolutionizing PTC molecular typing for precise high-risk identification.</p>","PeriodicalId":11884,"journal":{"name":"European Journal of Endocrinology","volume":"192 2","pages":"128-140"},"PeriodicalIF":5.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143491292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
