Evaluation of a new method for the diagnosis of alterations of Lens culinaris agglutinin binding of thyroglobulin molecules in thyroid carcinoma.

چکیده
BACKGROUND The measurement of serum thyroglobulin (Tg) is widely used as a marker for recurrence of thyroid carcinoma following total thyroidectomy. However, this method cannot differentiate between benign and malignant disease. We focused on the sugar chain in the Tg molecule and investigated the usefulness of Lens culinaris agglutinin (LCA)-reactive Tg ratios in sera and wash fluids obtained during fine-needle aspiration (FNA) for the detection of thyroid carcinoma. METHODS The study was performed using 203 serum samples (115 from patients with benign thyroid disease and 88 from patients with thyroid carcinomas) and 176 wash fluid samples (143 benign, 21 malignant, and 12 inconclusive). LCA-reactive Tg ratios were determined using an enzyme-linked immunosorbent assay, and a comparison was made between malignant and benign lesions. RESULTS In serum, the ratio in patients with malignancy was 79.5+/-6.0 [mean+/-standard deviation (SD)], significantly lower than in patients with benign lesions (84.9+/-3.5). The ratios in wash fluid from malignant lesions (75.8+/-18.9) were also significantly lower than those from benign lesions (85.6+/-3.9). CONCLUSIONS These results suggest that this method could distinguish between benign and malignant lesions and may be useful for screening serum and wash samples.

The clinical utility of Lens culinaris agglutinin-reactive thyroglobulin ratio in serum for distinguishing benign from malignant conditions of the thyroid.
BACKGROUND Traditionally, the follow-up of differentiated thyroid carcinoma consists of periodic withdrawal from L-T4-suppressive therapy to allow performance of a highly sensitive serum Tg measurement to detect recurrences. We investigated Lens culinaris agglutinin-reactive thyroglobulin ratios in serum to evaluate in usefulness for detection of thyroid carcinoma. METHODS The study was condu...

The treatment of patient with differentiated carcinoma of thyroid consists of three stages, surgery, I 1.1.i ablation and hormone therapy. To avoid the problems mentioned in the article, initially the patient should have thyroid scan, T.1 , T4, thyroglobulin estimation and a chest x-ray, prior to surgery which should be carried out by a competent surgeon, in order that total thyroidectomy can b...

Background: Thyroid carcinoma is the most frequent malignant tumor of the endocrine system in human body and accounts for nearly 1% of all cancers. Medullary thyroid carcinoma is the third frequent of thyroid cancer and accounts about 5-8% of thyroid cancer. Osteocalcin, known as a Bone Gamma-carboxyglutamic Acid-containing Protein (BGLAP), is the most non collagenous protein. Retinol binding p...
متن کاملHow to manage patients with undetectable thyroglobulin but thyroid residue after radioiodine ablative therapy in differentiated thyroid carcinoma, retreatment or observation?
Introduction:Differentiated thyroid carcinoma (DTC) follow-up after thyroidectomy and radioiodine-ablation is performed mainly by thyroglobulin (Tg), diagnostic iodine-131 whole body scan (DxWBS) and sonography. Some patients with undetectable Tg have thyroid-bed uptake after ablation in whom decision making regarding the need for retreatment is still controversial. Me...

This study was done in research institute of nuclear medicine from 1988-1992 for evaluation of the value of serum thyroglobulin level in comparison with 1-131 whole body scan (1-131 WBS) in patients with differentiated thyroid carcinoma. 204 patients who had total or near total thyroidectomy treated with 1-131 were evaluated in this study. Out of 204 patients 136 di...
