There is also a clear association between radiation exposure (from radiotherapy or fallout) and incidence of papillary thyroid carcinoma. [16] Port et al reported that papillary thyroid cancers in patients exposed to radiation from the Chernobyl accident could be completely distinguished from sporadic papillary thyroid cancers in patients with no history of radiation exposure, on the basis of gene expression patterns involving seven genes (ie, SFRP1, MMP1, ESM1, KRTAP2-1, COL13A1, BAALC, PAGE1).
