From 1995 to 2016, the rate of thyroid cancer in Iredell County, North Carolina, was more than double the expected rate for the entire state.
Now, a new report released by the N.C. Thyroid Panel offers recommendations for the top-priority research needed to understand the alarming patterns and potential causes of thyroid cancer.
Occurrences of thyroid cancer have been rising globally and in North Carolina since the mid-1990s. The causes of the disease are poorly understood, with the only known risk factors being childhood exposure to ionizing radiation and obesity.
In spring 2019, the UNC Lineberger Comprehensive Cancer Center convened a panel of expert scientists and other stakeholders to identify research needs related to thyroid cancer in the state. Dr. Andrew F. Olshan, Barbara Sorenson Hulka Distinguished professor in Cancer Epidemiology at the University of North Carolina Gillings School of Global Public Health and associate director for population sciences at UNC Lineberger, served as the panel chair.
“Our goal,” he says, “was to advise on what it would take to investigate the cancer patterns in the state, and parse through multiple competing explanations for those patterns.”
Ultimately, the report recommends ten areas for further research on thyroid cancer, including: Developing an N.C. thyroid cancer patient study to gather new information on factors that might influence development of the disease; examining patterns of health care utilization; conducting geospatial analyses of cancer cases to determine if there are other increases in thyroid cancer across the state; and communicating with epidemiologists in other states where similar trends have been documented.Friday Letter Submission, Publish on August 23
