An investigation of galectin-3 and thyroglobulin using IFA was conducted in 80 patients. A lavage of aspirate from the thyroid gland was obtained by fine-needle aspiration biopsy. It was stated that significant increase of galectin-3 and thyroglobulin was noted in case of high differentiated thyroid carcinoma in comparison with benign nodules. Galectin-3 and thyroglobulin from the lavage of thyroid gland aspirate could be used as an oncological marker for complex differentiated diagnostics of high differentiated thyroid carcinoma and benign nodules.

Objective: There are conflicting data on the risk of thyroid cancer in thyroid nodules 3 cm or larger, and few such studies on this issue have been conducted in Asia. This study aimed to examine the risk of thyroid cancer in patients with thyroid nodules 3 cm or larger. Methods: This was a 7-year retrospective study conducted in a tertiary referral hospital in Taiwan. All patients with a thyroid nodule measuring ≥3 cm who underwent thyroid operation with or without fine-needle aspiration biopsy (FNAB) were included. The prevalence rate of thyroid cancer, as well as the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and false-negative rate of FNAB for thyroid nodule ≥3 cm were also examined. Results: A total of 132 patients were included in this study. Thyroid cancer was detected in 19 of 132 (14.4%) thyroid nodules measuring ≥3 cm. The performance of FNAB for detecting cancer in nodules 3 cm or larger without considering other ultrasonography parameters was relatively poor with a sensitivity of 50%, but the specificity (100%), PPV (100 %), and NPV (93.4 %) were excellent. Conclusion: The risk of thyroid cancer for thyroid nodules ≥3 cm in this study was low. The PPV and NPV of FNAB were high for the detection of cancer in large nodules. The decision to perform thyroidectomy should not be solely based on nodule size and should include other factors, such as ultrasound characteristics and surgical risk.

Background. The diagnostic efficacy of the molecular analysis that included determination of papillary thyroid carcinoma (PTC) marker gene expression levels and BRAF mutation in fine-needle aspiration biopsy material was evaluated in a prospective study of patients with thyroid nodules. Materials and methods. Totally, 36 patients (29 females and 7 males) with thyroid nodules were included in the study. The mRNA expression of genes (SFTPB and TFF3) was estimated in relation to a housekeeping gene level (KPNA4) by means of duplex RT-PCR followed by the band intensity measurement. Detection of BRAF mutation was performed by PCR followed by direct sequencing. Results. In 25/32 (78.1%) cases, results of the molecular test were in agreement with the cytological diagnosis (7/7 PTC and 18/25 non-PTC) further confirmed by histological examination of tissues surgically removed from all seven PTC patients and 10 individuals with benign nodules. In 7/32 patients (21.9%) there was a discrepancy between cytological findings and molecular results, which revealed a benign nodule and a PTC-like pattern, respectively. Upon a repeated examination of five of these patients about one year later, three were cytologically diagnosed with PTC (all patients had been operated on), and the diagnosis of the other two patients remained unchanged. Conclusions. The results have demonstrated that the molecular analysis of FNAB material is an informative means of the preoperative diagnosis of thyroid nodules as it allows identification of patients with suspected PTC before other diagnostically significant changes take place.

Nodular goiter is a rare condition in children and adolescents and compared with adults, thyroid nodules are more frequent malignant in pediatric population. We have investigated the prevalence of thyroid carcinoma among the thyroid disorder emphasizing on the surgical treatment in term of indication, methods and complications. Retrospective study of 35 children and adolescents with nodular goiter. Demographic data, thyroid ultrasonographic features, fine needle biopsy aspiration, hormonal profile, surgical treatment procedure as well as histological aspects were recorded. Study included 26 (74%) girls and 9 (26%) boys with a mean age of 11.66 years. Fine needle aspiration biopsy was performed in 10 cases due to the TIRADS score � 4 with Bethesda II in 3 cases, Bethesda III in 4 cases and Bethesda V in 3 cases. The surgical treatment was performed in 16 (45.7%) cases due to fine needle aspiration biopsy results or due to the relapse after medical treatment. Lobectomy was performed in 7 (43.7%) cases while total thyroidectomy was the final option for the rest of 9 (56.3%) patients. As a result of pathological examination in 8 cases the thyroid carcinoma has been found. The rest of 8 patients presented benign thyroid findings (follicular adenoma, toxic adenoma and Graves� disease with follicular adenoma). The prevalence of thyroid carcinoma among the pediatric population with thyroid nodules was 22.8% most affected being the female gender.

PURPOSE: Thyroid cancer is the most frequently occurring endocrine malignancy; however, preoperative diagnosis of some lesions, in particular those with follicular histology, is difficult, and a consistent number of nototherwise-specified “follicular nodules” are surgically resected more for diagnosis than therapeutic purposes. In this study, we investigated whether the lectin-related molecules CD44v6 and galectin-3, the expression of which is altered during deregulated cell growth and malignant transformation, could be potential markers for improving the diagnostic accuracy of conventional cytology. MATERIALS AND METHODS: A comparative immuno-chemical and molecular analysis was performed on 157 thyroid specimens representative of normal, benign, and malignant tissues, and on 36 cytologic samples obtained preoperatively by fine-needle aspiration biopsy from nonselected patients with palpable thyroid nodules. RESULTS: Normal thyrocytes did not express galectin-3 nor CD44v6. Although the expression of CD44v6 isnegligible in thyroiditis, these molecules are variably detected in benign and malignant proliferative lesions. Interestingly, galectin-3 is never expressed in benign lesions, but it is invariably detected in cancers. A comparative evaluation of CD44v6 and galectin-3 expression in thyroid malignancies demonstrated that these molecules are coexpressed at the messenger RNA and protein level in almost all lesions. CONCLUSION: Our findings suggest that CD44v6 and galectin-3 could be potential markers to preoperatively identify malignant transformed thyrocytes. Immunodetection of these molecules on cytologic specimens obtained by fine-needle aspiration biopsy is an accurate and improved method for selecting, on a molecular basis, those nodular lesions of the thyroid gland that need to be surgically resected.
