Context: Use of BRAF mutation in papillary thyroid cancer (PTC) has the potential to improve risk stratification this cancer. Objective: The objective study was investigate prognostic value patients with PTC. Design, Setting, and Subjects: In a multicenter 219 PTC patients, data on their clinicopathological characteristics clinical courses between 1990 2004 were retrospectively collected, tumor status determined. Associations initial subsequent recurrence analyzed. Main Outcome Measure:...

The BRAF gene has been found to be activated by mutation in human cancers, predominantly malignant melanoma. We tested 476 primary tumors, including 214 lung, 126 head and neck, 54 thyroid, 27 bladder, 38 cervical, 17 prostate for the T1796A polymerase chain reaction (PCR)-restriction enzyme analysis of exon 15. In 24 (69%) 35 papillary thyroid carcinomas examined, we a missense thymine (T)-->adenine (A) transversion at nucleotide 1796 (T1796A). was detected four lung cancers six neck but...

This analysis was performed to determine the effect of initial therapy on outcomes thyroid cancer patients. The study setting a prospectively followed multi-institutional registry. Patients were stratified as low risk (stages I and II) or high III IV). Treatments employed included near-total thyroidectomy, administration radioactive iodine, hormone suppression therapy. Outcome measures overall survival, disease-specific disease-free survival. Near-total aggressive each independently...

Recombinant human TSH has been developed to facilitate monitoring for thyroid carcinoma recurrence or persistence without the attendant morbidity of hypothyroidism seen after hormone withdrawal. The objectives this study were compare effect administered recombinant with withdrawal on results radioiodine whole body scanning (WBS) and serum thyroglobulin (Tg) levels. Two hundred twenty-nine adult patients differentiated cancer requiring WBS studied. Radioiodine Tg measurements performed...

To detect recurrent disease in patients who have had differentiated thyroid cancer, periodic withdrawal of hormone therapy may be required to raise serum thyrotropin concentrations stimulate tissue so that radioiodine (iodine-131) scanning can performed. However, causes hypothyroidism. Administration recombinant human stimulates without requiring the discontinuation therapy.

BACKGROUND A novel prognostic staging classification encompassing all forms of thyroid carcinoma was created for the National Thyroid Cancer Treatment Cooperative Study (NTCTCS) Registry, with goal prospective validation and comparison other available classifications. METHODS Patient information recorded prospectively from 14 institutions. Clinicopathologic based on patient age at diagnosis, tumor histology, size, intrathyroidal multifocality, extraglandular invasion, metastases,...

Dyslipidemia increases the risk of atherosclerotic cardiovascular disease and is incompletely reversed by statin therapy alone in many patients. Thyroid hormone lowers levels serum low-density lipoprotein (LDL) cholesterol has other potentially favorable actions on metabolism. Consequently, thyromimetic drugs hold promise as lipid-lowering agents if adverse effects can be avoided.We performed a randomized, placebo-controlled, double-blind, multicenter trial to assess safety efficacy compound...
