Abstract Introduction: Differenciated thyroid carcinoma (DTC) stand for 80% of malignant disease of the thyroid gland. DTC generally has a good prognosis and benign course. Several studies concluded that specific patient risk factors and tumor type determine their clinical course. The aim of the study was to define global survival and identify risk factors. Methods: We performed a descriptive and retrospective analysis of DTC patients who were surgically treated at the Head and Neck Surgery Service at Carlos Andrade Marin Hospital from 1980 to 2010. Demographic variables, tumor related variables and type of tumor were recorded. Kaplan Meier survival curves and long Rank test were obtained. Cox model was used to assess prognostic factors. Results: Of 353 DTC treated patients, the 5-year overall survival rate for follicular type was 65.4% and for papillary type 90.1%. A 10-year overall survival rate for follicular type was 41.5% and for papillary tipe 76.9 %. Finally, a 15-year overall survival rate for follicular type was 33.2 % and for papillary type 66.5%. Univariate analysis showed that factors like age (p 0,002), ETE ( p 0,001) and histological lymph node invasion (p 0,002) were significant. Discusion: Variables like age, ETE and histological lymph node invasion were found to be significant prognostic survival factors in DTC patients.
