The Estimation of Thyroid Cancer Risk based on Type 2 Diabetes Mellitus and ABO Blood Group

Abstract

OBJECTIVEMultiple potential risk factors have been proposed for the development of thyroid cancer. Type 2 diabetes and ABO blood group had a significant relationship with some cancers. These agents may be relatedto thyroid cancer. This study investigates the association between thyroid cancer and diabetes and theABO blood group.METHODSThis analytic study was conducted in patients with thyroid cancer (n=87) and the individuals cancerfree (n=929). The odds ratio of thyroid cancer was estimated in diabetic patients after adjusting age andsex. The distribution of the blood groups in both groups was determined and compared with considering confidence interval 95%.RESULTSWe observed a significant association between thyroid cancer and type 2 diabetes (odds ratio (OR): 4.42,95% confidence interval (CI): 2.04-9.57, p
