Abstract
INTRODUCTION
The hypothesis of an association between papillary thyroid carcinoma (PTC) and chronic lymphocytic thyroiditis (CLT) continues to generate debate. Retrospective studies suggest that there is a greater probability of diagnosing a PTC in surgical specimens with CLT; however, prospective studies suggest that there is no true increase in risk.
METHODS
An analytical, cross-section measurement and retrospective study was carried out considering gender, age and diagnosis of CLT and PTC in surgical specimens. A binary logistic regression model was proposed to predict the probability of carrying out the diagnosis of PTC based on the diagnosis of CLT, gender and age.
RESULTS
The study population consisted of 1136 patients, 1047 (92.2%) women and 89 (7.8%) men, with an average age of 47.5±14.3 years. The prevalence of CLT and PTC was 14.9% and 16.1% respectively. Coexistence between PTC and CLT was found in 44 patients, corresponding to 3.9% of the population. Our logistic regression model suggests that the probability of diagnosing PTC in surgical specimens of male patients under 40 years old and with CLT is 53.8%.
CONCLUSIONS
We suggest that there is a greater probability of diagnosing PTC in surgical specimens with confirmatory histological data for CLT; in addition, in males under 40 years old this probability increases.
