The clinical and histopathological characteristics of thyroid gland diseases in adolescents requiring surgical treatment: a ten-year follow-up study.

The present research aimed to determine the clinical and pathohistological characteristics of thyroid gland diseases in adolescents who were previously surgically treated at the Endocrine Surgery Center of the University Medical Center of Serbia from 01/01/2001 to 01/01/2011. The study covered 170 patients of both sexes from the population of adolescents (aged 16 to 20 years) with various malignant and benign thyroid gland diseases. The data for this study were extracted from the medical histories of patients and the electronic database of the Center for Endocrine Surgery. Detailed data analysis included diagnosis, symptomatology, surgical intervention type, and disease stage. The following thyroid status parameters were analyzed from preoperative data: thyroxine (T4), thyroxine free fraction (FT4), triiodothyronine (T3), triiodothyronine free fraction (FT3), and thyroid stimulating hormone (TSH). In addition, the pathohistological features of diagnosed thyroid diseases were also determined, with a special focus on the presence of well-differentiated cancers. Papillary carcinomas were the most common of well-differentiated cancers in adolescents over the ten-year follow-up period. Based on the assessed data, total thyroidectomy was the most commonly used type of surgical intervention in these patients. The conducted research provides essential information related to both the biological characteristics and diagnostics of these cancers and their surgical treatment in such a sensitive population. Moreover, research showed that the clinical presentation of thyroid cancer in adolescents is almost identical to that in adults.
