Abstract

Papillary thyroid cancer (PTC) has a good prognosis, but about 30% of individuals with the disease may develop more aggressive tumors. However, the mechanisms that lead to greater aggressiveness in PTC are not clear. In this purpose, the objective of this study was to investigate the association between the frequency of food consumption and the predictors of tumor histopathological prognosis of PTC. Forty-seven individuals with PTC had their eating habits investigated by a semi-quantitative Food Frequency Questionnaire (FFQ), focusing on the food or food group previously associated with TC. Foods consumed more than 1x / week by at least 50% of the patients were individually investigated for associations with the predictors of PTC histopathological prognosis: invasion, extrathyroidal extension, multicentricity, lymph node metastasis and tumor size.
