{"title":"Controversies Surrounding IGF-I Receptor Involvement in Thyroid-Associated Ophthalmopathy.","authors":"Terry J Smith","doi":"10.1089/thy.2024.0606","DOIUrl":"10.1089/thy.2024.0606","url":null,"abstract":"<p><p><b><i>Background:</i></b> Thyroid-associated ophthalmopathy (TAO, aka thyroid eye disease [TED], Graves' orbitopathy) remains poorly understood and inadequately treated since its initial description. It is disfiguring, can threaten vision, and represents an autoimmune process closely associated with thyroid disease. Unambiguous connections linking TAO to the glandular maladies of Graves' disease (GD) remain incompletely clarified. Detecting the thyrotropin receptor (TSHR) in periocular tissues suggests that this cell-surface protein represents a shared autoantigen with the thyroid gland, but we now know that its expression is ubiquitous. Most patients with TAO have relatively high circulating levels of activating anti-TSHR autoantibodies. Emerging more recently is the importance of insulin-like growth factor I receptor (IGF-IR) in the pathogenesis of TAO. The TSHR/IGF-IR signaling complex apparently drives circulating fibrocytes and the unique phenotypes of fibroblasts inhabiting the TAO orbit (GD-OF). <b><i>Methods:</i></b> The PubMed database was scanned for articles dating back to the earliest time periods covered. Keywords used for primary searches included thyroid-associated ophthalmopathy, Graves' orbitopathy, TED, orbit, TSH receptor, IGF-I receptor, and autoimmune thyroid disease. Secondary searches used numerous other search terms. <b><i>Results:</i></b> GD-OF have been characterized extensively as being particularly responsive to the immunological factors and key effectors in TAO pathogenesis. Both TSHR and IGF-IR are overexpressed by GD-OF and CD34⁺ fibrocytes and form a signaling complex. They are activated through this TSHR/IGF-IR complex to produce large amounts of hyaluronan and express multiple cytokines. This complex mediates cellular responses to pathogenic IgGs in TAO. CD34⁺ fibrocytes and CD34⁺ OF also express relatively high levels of multiple thyroid autoantigens. Identifying IGF-IR as a key component of a receptor complex and its intertwining signaling activities with those of TSHR has led to a targeted medical therapy for TAO. This therapy involves the selective systemic inhibition of IGF-IR. <b><i>Conclusions:</i></b> Much has been learned over the preceding decades about the pathogenesis of TAO. Among these is the identification of IGF-IR as a pivotal component underpinning the disease. This has led directly to development of an effective targeted therapy. Important gaps in our understanding persist, and current therapies have limitations. Thus, despite these advancements, considerably more remains to be achieved.</p>","PeriodicalId":23016,"journal":{"name":"Thyroid","volume":" ","pages":"232-244"},"PeriodicalIF":5.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143256671","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}

TC overdiagnosis leads to overtreatment, lifelong medical care, and side effects. This study systematically quantifies the epidemiological profile of TC incidence in China, as well as estimating TC incidence attributable to overdiagnosis. <b><i>Methods:</i></b> Data were derived from the Cancer Incidence in Five Continents databases. Age-standardized incidence rates (ASIRs) per 100,000 person-years were calculated using the world standard population. Joinpoint regression and age-period-cohort models were conducted to examine temporal ASIR trends and period effects, respectively. We estimated TC incidence attributable to overdiagnosis among patients aged 15-84 years by comparing shapes of age-specific curves with those observed before diagnostic practices. <b><i>Results:</i></b> In 2013-2017, there were 37,862 and 117,979 new TC cases in males and females in China, respectively, with ASIRs of 6.9/100,000 and 21.1/100,000. Significant upward trends were observed from 1993 to 2017, with average annual percent changes being 14.7% for males and 16.2% for females. Incidence rate ratios of period effects markedly increased from 1.0 to 61.8 for males and from 1.0 to 42.9 for females from 1993 to 2017. Overdiagnosis accounted for 83.5% (31,455/37,685) and 88.7% (104,222/117,509) of cases in males and females in 2013-2017, respectively, yielding ASIRs of 5.9/100,000 and 19.1/100,000. ASIRs attributable to overdiagnosis in urban populations (6.9/100,000 for males and 21.7/100,000 for females) were significantly higher than in rural populations (1.3/100,000 and 6.4/100,000). Among the 25 included provinces, ASIRs attributable to overdiagnosis ranged from 0.3/100,000 in Sichuan to 18.5/100,000 in Shanghai in males and from 0.1/100,000 in Shanxi to 49.4/100,000 in Shanghai in females.

The location of the tumor was classified into epidermis, dermis, or hypodermis on the basis of the involved skin layer. After RFA, the technique efficacy (absence of detectable vasculature and volume reduction at 12 months), clinical success (resolution of symptoms or cosmetic problems), volume reduction ratio (VRR), complete disappearance of tumor, and complications were assessed. <b><i>Results:</i></b> Of the 50 recurrent tumors, 9 involved the epidermis, 10 involved the dermis, and 31 involved the hypodermis. A total of 88 RFA sessions (mean, 1.8; range: 1-6) were performed. The technique efficacy at 1 year was 72% (36/50 [confidence interval or CI: 59.6-84.4%]).
