Environmental Factors and Thyroid Cancer
NCT05172921 · View on ClinicalTrials.gov ↗
Study Summary
Thyroid cancer incidence has been steadily increasing and has nearly tripled since the 1970's in the US and worldwide. Early detection of small, papillary thyroid cancers using high quality diagnostic imaging explains only about 50% of this increased incidence, suggesting that there is a true increase in the occurrence of thyroid cancer and that changes in the prevalence of environmental risk factors might play a role in thyroid cancer etiology and progression. Yet, the cascade of environmental triggers linked to thyroid cancer remains elusive. 'Exposomics' studies all health relevant chemical exposures that an individual experiences, and leverages metabolomic platforms to estimate the "internal" environment, informing both exogenous exposures and the metabolic products that lead to, or arise from, disease. Besides exposure to ionizing radiation as known modifiable risk factor, epidemiological evidence suggests that exposure to endocrine disrupting chemicals may be a potential thyroid cancer risk factor due to their known effects on thyroid function. However, these studies relied either on exposure questionnaires which are susceptible to recall bias, or used a limited set of targeted biomarkers measured after diagnosis for testing associations with case-control status, and not thyroid cancer prognosis. Further, the molecular basis for observed associations with thyroid cancer remains unclear. To address the overall hypothesis that environmental exposures alter metabolic pathways and therefore affect thyroid cancer prognosis, small amounts of blood will be collected using dried blood microsampler technology (e.g. Mitra® sampling devices), which is minimally invasive and can be used to collect repeated blood measurements at home, without the need for specialized training. These dried blood samples will be used to perform metabolomics experiments, which describe the sum of exogenous exposures, metabolic alterations, and biological response. Additional exposure assess

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05172921
The ClinicalTrials.gov registry entry for NCT05172921 describes a study currently listed as recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 500 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Icahn School of Medicine at Mount Sinai, which has 946 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Thyroid Cancer appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05172921 reports 1 study location spanning 1 distinct geographic area — top geographies include New York. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
