The contract is for the continuation of the “Study of Thyroid Cancer and Other Thyroid Diseases in Belarus”, a large-scale epidemiological study detecting thyroid and other pathology in persons who have been exposed to radiation as released by the accident at the Chernobyl Nuclear Power Station in April 26, 1986. The study involves two cohorts: (1) the “main cohort” that was established in the late 1990s and consists of 11,732 subjects who were age 18 or under at the time of the accident, had their dose to the thyroid gland measured, and lived in the Chernobyl affected areas in Belarus; and (2) the “in utero cohort” that was established in 2017 and consists of 2.965 persons who were exposed to Chernobyl fallout radiation in utero and early post-natal life. The main emphasis of this contract is to conduct medical screening for thyroid cancer and diseases in the recently established in-utero cohort. The main cohort, after having undergone three cycles of thyroid screening, transitioned to linkage-based passive follow-up. The specific objectives are: for the in utero cohort, (1) to conduct medical screening for thyroid cancer and thyroid non-cancer disease; (2) to evaluate the reliability of questionnaire-based doses previously reconstructed; for both the main and in utero cohorts: (3) to maintain passive follow-up to update occurrences of thyroid cancer, other cancer and thyroid non-cancer disease, through linkage with the Chernobyl State Registry and the National Belarusian Cancer Registry, (4) update demographic, clinical and epidemiologic data through a mail survey. Medical screening of in utero cohort focuses on thyroid cancer but also ascertain a wide spectrum of benign lesions, including benign tumors, nodules, functional changes (hyper- or hypothyroidism, thyroiditis, etc.), which have been associated with radioiodine exposure. Another important aspect of the study is the evaluation of uncertainty of questionnaire-based doses due to memory recall. NCI’s previous study shows that if dose-related measurements are available for study subjects, the quality of individual behavior and dietary data has, in general, a small influence on the results of the retrospective dose assessment. However, direct thyroid measurements are available only for around 15% of mothers of in utero cohort subjects; evaluation of uncertainty in doses due to possibly poor memory recall is important for this study. Another task for the contract is to update the dataset for the main and in-utero cohort with information obtained as a result of record linkage to the State Chernobyl Registry and National Belarusian Cancer Registry. We are also updating vital status and last known address for the subjects of main cohort through a mail survey.

该合同旨在继续进行“白俄罗斯甲状腺癌和其他甲状腺疾病的研究”，这是一项大规模流行病学研究，旨在检测受到切尔诺贝利核电站事故释放的辐射的人的甲状腺和其他病理状况1986 年 4 月 26 日站。该研究涉及两个队列：（1）“主要队列”，成立于 20 世纪 90 年代末，包括事故发生时年龄在 18 岁或以下、居住在白俄罗斯切尔诺贝利受影响地区的 11,732 名受试者接受了甲状腺剂量测量；(2) 2017 年建立的“子宫内队列”；包括 2,965 名在子宫内和产后早期暴露于切尔诺贝利辐射的人员。该合同的主要重点是对甲状腺癌和疾病进行医学筛查。在最近建立的子宫内队列中，主要队列在经历三个周期的甲状腺筛查后，转变为基于连锁的被动随访。 具体目标是：对于子宫内队列，(1) 对甲状腺癌和甲状腺非癌症疾病进行医学筛查；(2) 评估先前重建的基于问卷的剂量的可靠性；队列：(3) 通过与切尔诺贝利国家登记处和白俄罗斯国家癌症登记处联系，维持被动随访，更新甲状腺癌、其他癌症和甲状腺非癌症疾病的发生情况， (4) 通过邮件调查更新人口统计、临床和流行病学数据。 子宫内队列的医学筛查重点关注甲状腺癌，但也确定广泛的良性病变，包括良性肿瘤、结节、功能变化（甲状腺功能亢进或减退、甲状腺炎等），这是与放射性碘暴露相关的另一个重要因素。该研究的一个方面是评估由于记忆回忆而导致的基于问卷的剂量的不确定性，NCI 之前的研究表明，如果研究对象可以获得剂量相关的测量结果，那么个人行为和饮食数据的质量就会受到影响。一般而言，对回顾性剂量评估的结果影响很小，但是，仅对大约 15% 的子宫内队列受试者母亲进行直接甲状腺测量；由于记忆能力可能较差，因此评估剂量的不确定性对于本研究很重要。 。 合同的另一项任务是使用通过与国家切尔诺贝利登记处和国家白俄罗斯癌症登记处的记录链接获得的信息来更新主要队列和子宫内队列的数据集。我们还在更新生命状态和最后已知地址。通过邮件调查确定主要队列的受试者。
