OBJECTIVES: The incidence of papillary thyroid carcinoma increased in several countries. The purpose of this study was to quantify the changes in thyroid carcinomas in our University Hospital.
STUDY DESIGN: Retrospective study.
METHODS: All 1.927 thyroidectomy cases studied in the Pathology Department of Hotel-Dieu de France Hospital (Beirut, Lebanon), between 2003 and 2013, were included.
RESULTS: The Female/Male Sex Ratio of the studied population was 3.7/1. The mean age of female patients was significantly lower than that of male patients. The most frequent diagnoses were multinodular goiter (78%) and papillary-carcinoma (26%). 337 cases had a single lesion on gross examination. 21 of them were diagnosed with follicular carcinoma and 59 with follicular adenoma. A statistically significant correlation was found between the unicity of the lesion on gross examination and the final diagnosis of a follicular neoplasm. Thyroid carcinoma was multifocal in 33% of the cases and bilateral in 24%. A statistically significant increase in thyroid carcinoma proportion (from 15% in 2003 to 44% in 2013) was found. Among all thyroid carcinomas, the proportion of papillary type increased from 65% in 2003 to 94% in 2013 ; this increase remained statistically significant after the exclusion of papillary micro-carcinomas, whose proportion was stable throughout the 11 years.
CONCLUSIONS: In this study, we noted a statistically significant increase in the frequency of thyroid carcinoma, especially of the papillary type. The unicity of the lesion on gross examination is significantly associated with a follicular neoplasm.
