This study provides the first extensive assessment of incidence patterns and temporal trends of pediatric DTC in Germany, using the best available data from the German Malignant Endocrine Tumor (MET) Registry and the German Childhood Cancer Registry (GCCR) covering a period of 25 years. <b><i>Patients and Methods:</i></b> We conducted a register-based incidence and time series analysis, identifying all children and adolescents diagnosed with DTC at ages 0-17 years between 1997 and 2021 in Germany, as recorded in the German MET Registry and/or the GCCR. Age-specific and age-standardized incidence rates (ASR) over time, average annual percentage changes (AAPC), and cross-tabulations were used to evaluate incidence and temporal patterns. <b><i>Results:</i></b> We identified 469 DTC cases, including 85.7% papillary thyroid cancer and 9.4% follicular thyroid cancer. The average ASR for the period 1997-2021 was 1.16 per million, with higher rates in females compared with males (1.64 vs. 0.72 per million, respectively). Incidence rates increased with increasing age. The overall ASR increased from 0.84 per million in 1997-2001 to 1.48 per million in 2017-2021, with an AAPC of 3.46% [confidence interval or CI: 2.12-4.83]. The increase was most pronounced in adolescents aged 15-17 years (AAPC: 6.79% [CI: 4.43-9.19]). The proportion of incidentalomas rose from 5% in 1997-2001 to 26% in 2017-2021, yet we observed no marked shift in tumor size between symptomatic and incidental cases. <b><i>Conclusions:</i></b> Our study revealed a significant increase in pediatric DTC incidence in Germany, most pronounced among adolescents. The observation of an increasing incidence mirrors global trends and presents a complex public health challenge. While improved detection likely contributes to this trend, the stable tumor size distribution suggests that other factors are also in play. The rising detection of incidentalomas suggests enhanced diagnostic practices unrelated to symptoms of thyroid neoplasia. These findings highlight the need to carefully evaluate diagnostic and screening practices in pediatric populations.</p>","PeriodicalId":23016,"journal":{"name":"Thyroid","volume":" ","pages":"1540-1550"},"PeriodicalIF":5.8,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142547626","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}

While this increase is partially due to increased detection, environmental pollutants have also emerged as a possible contributing factor. Our goal was to perform a systematic review to assess the relationship between environmental air pollution and thyroid cancer. <b><i>Methods:</i></b> Systematic literature search was performed using PubMed, EMBASE, Cochrane Library, Web of Science, and Scopus databases for original articles published prior to March 2024, investigating outdoor air pollution and thyroid cancer/nodules (PROSPERO CRD42024517624). Inclusion criteria included quantitative reporting of pollutant levels and effect size. Specific pollutants included ozone (O<sub>3</sub>), particulate matter less than 2.5 (PM<sub>2.5</sub>) or 10 microns in diameter (PM<sub>10</sub>), sulfur dioxide (SO<sub>2</sub>), nitric oxides (NO<sub>x</sub>), carbon monoxide (CO), and polyaromatic hydrocarbons (PAHs). Study design, sample size, pollution assessment method, covariates, and strength/direction of associations between pollutants and thyroid cancer/nodule detection were extracted, and descriptive synthesis was utilized to summarize pertinent findings. Risk of bias was assessed using the National Heart, Lung, and Blood Institute quality assessment tool. <b><i>Results:</i></b> Of 1294 identified studies, 11 met inclusion criteria.

This study reported the clinicopathological characteristics of patients with thyroid cancer diagnosed through the FHMS and treated at the Fukushima Medical University Hospital. <b><i>Methods:</i></b> Data regarding the clinicopathological characteristics of patients with thyroid cancer were collected and evaluated in this descriptive study. <b><i>Results:</i></b> Among the 263 patients diagnosed with thyroid cancer as of September 2021, 220 patients with cytologically diagnosed thyroid cancer were treated as referrals from the FHMS.

Questions regarding the extent of patient involvement in shared decision-making (SDM) processes persist; this is particularly pertinent to patients considering treatment options for low-risk papillary thyroid cancer (PTC). In this study, we aimed to explore Chinese young adults' experiences of SDM relating to the choice of treatment for low-risk PTC. <b><i>Methods:</i></b> The study used a qualitative descriptive design and semistructured interviews. Interviews were conducted with 24 patients (ages ranging from 18 to 38 years; 4 men and 20 women) diagnosed with low-risk (PTC) between March 2023 and May 2024. Twenty-two of 24 patients' tumor size measured 1 cm or smaller; the largest tumor size measured 1.47 cm. Reflexive thematic analysis was used to identify key themes from the transcribed interviews. <b><i>Results:</i></b> The analysis revealed that the SDM experiences of young patients with low-risk PTC involve four themes: challenges in information sharing; reasons for information seeking; factors influencing decision making; and self-positioning in treatment decision making. Three self-positions relating to treatment decision making were identified. These included dependent positioning, which reflects a \"paternalistic\" decision-making pattern; collaborative positioning, reflecting a \"sharing\" of decision making; and autonomous positioning, reflecting an increased sense of personal responsibility for both managing their health and engagement in decision making. Limited treatment options being offered, overuse of medical terminology, and communication gaps between clinicians and patients were the main challenges described during the information-sharing process. Information that needs persisting after physician-patient consultations resulted in active information-seeking behavior. The key variables identified in this study that potentially affected the decision-making process were future personal considerations, language used to discuss cancer, and negative emotions. <b><i>Conclusions:</i></b> These results highlight the necessity of adopting flexible strategies when supporting collaborative treatment decision making in the context of the doctor-patient interaction for low-risk PTC. Based on these findings, clinicians can take measures to enhance the quality of SDM by inquiring about patients' role preferences, providing details of the full range of treatment options, and encouraging patients to share their preferences and concerns relating to possible treatment options.</p>","PeriodicalId":23016,"journal":{"name":"Thyroid","volume":" ","pages":"1486-1494"},"PeriodicalIF":5.8,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142475410","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}
