Preoperative serum thyroglobulin concentration as a predictive factor of malignancy in small follicular and Hurthle cell neoplasms of the thyroid glandPetrič, Rok, 1972- ; Bešič, Hana ; Bešić, NikolaBackground Cytologic examination of a fine-needle aspiration biopsy specimen cannot distinguish between benign and malignant follicular or Hurthle cell neoplasms. Serum thyroglobulin (Tg) ... concentrations are higher in follicular and Hurthle cell carcinomas than in benign follicular or Hurthle cell tumors, but preoperative measurement of Tg is not recommended for initial evaluation of thyroid nodules. The aim of this study was to find out whether preoperative serum Tg concentration is a predictive factor of malignant disease in patients with a follicular or Hurthle cell neoplasm with a diameter of 2 cm or less. Methods From 1988 to 2013, a total of 244 patients (214 female, 30 male, age range 9 to 82 years, median age 52 years) had a surgical procedure at our institute because of follicular or Hurthle cell neoplasms with a tumor diameter of 2 cm or less. In these patients a preoperative concentration of Tg was determined and Tg-autoantibodies were negative. The risk factors for malignancy were identified by a chi-square test and multivariate logistic regression. Results The histopathologic diagnoses were carcinoma, adenoma, and benign goiter in 62 (25.5%), 115 (47%), and 67 (27.5%) patients, respectively. The median preoperative Tg concentration in benign tumors, papillary carcinomas, follicular carcinomas, and Hurthle cell carcinomas was 41, 87, 72, and 106 ng/ml (P = 0.05), respectively. The predictive factors for carcinoma shown by the chi-square test were: sex, thyroid volume, and preoperative Tg concentration. The independent predictors of malignancy as shown by multivariate logistic regression were: male sex (odds ratio, 2.57; P = 0.02), and a Tg concentration of more than 80 ng/ml (odds ratio, 2.35; P = 0.005). Conclusion The independent predictors of malignancy in follicular or Hurthle cell neoplasms are sex and preoperative Tg concentration.Vir: World journal of surgical oncology [Elektronski vir]. - ISSN 1477-7819 (Vol. 12, no. 282, Sep. 2014)Vrsta gradiva - e-članekLeto - 2014Jezik - angleškiCOBISS.SI-ID - 1858427
