The effectiveness of the method for determining the level of thyroglobulin in needle washouts of fine-needle aspiration biopsy in the differential diagnosis of metastases of highly differentiated thyroid cancer in the lymph nodes of the neck

Introduction. Thyroid cancer is one of the most common malignant neoplasms endocrine system. well-differentiated thyroid constitutes about 90 % all tumors gland. Despite growing morbidity and high incidence this pathology, in case timely diagnosis treatment has favorable prognosis. Aim. using clinical examples, to demonstrate possibility thyroglobulin measurement needle washouts fineneedle aspiration biopsy detection cervical metastases highly differentiated cancer. Materials methods. five patients (2 with combined oncological 2 nodes gland, 1 patient after a thyroidectomy) adenopathy measured level wash out fluid lymph-nodes immunoradiometric method commercial kits Institute Isotopes-IRmA (Hungary). Results. Cervical were detected or excluded by determination fine-needle non-informational cytological studies. The useful diagnostic differential who have other morphological forms addition cancer, as well for history Conclusion. Determination puncture washout simple lymph neck several tumors.
