Number of Persons That Are Vitamin D Deficient in the Thyroid Nodule, Thyroid Cancer in Remission, and the Active Thyroid Cancer Groups. [ Time Frame: Within 12 months of enrollment in thyroid cancer collaborative registry (TCCR) database ]
We evaluated serum calcium,creatinine,albumin,and 25-hydroxyvitaminD(25-OH-D)in 42 thyroid nodule, 45 thyroid cancer in remission, & 24 active thyroid cancer patients. We also determined the number and percent of participants in each group that had vitamin D deficiency, defined as 25-OH-D < 30 ng/ml.
Assess percentage of persons with vitamin D levels in the deficient range (25-OH-D <30ng/ml) with active thyroid cancer compared to those in remission and controls. [ Time Frame: Within 12 months of enrollment in thyroid cancer collaborative registry database ]

Assess Vitamin D Levels in Those With & Without Thyroid Cancer
The Relationship Between Vitamin D and Thyroid Cancer
The purpose of this study is to evaluate Vitamin D levels in thyroid cancer patients with active disease compared with thyroid cancer patients in remission and patients with thyroid nodules.
Thyroid cancer is the most common endocrine related malignancy, increasing in incidence in recent years. There are relatively few, well known factors, both genetic and environmental, which predispose to the development of thyroid cancer. Vitamin D deficiency has been associated with other cancers, but the association between vitamin D and thyroid cancer is unknown. We plan to do a case control, pilot study to evaluate the relationship between vitamin D levels and thyroid nodules, thyroid cancer in remission, and active thyroid cancer.
Observational Model: Case Control

Non-Probability Sample
The Thyroid Tumor and Cancer Collaborative Registry (TCCR) is a thyroid cancer and thyroid nodule database at the University of Nebraska Medical Center. The database serves as a registry and biospecimen bank for those who wish to participate in multidisciplinary research. The database will be accessed to query for individuals with a diagnosis of thyroid cancer, both active disease and in remission, as well as a diagnosis of thyroid nodules. Those meeting eligibility requirements will then have their registry information and stored biospecimens accessed for testing and review.
