BACKGROUND: Neck ultrasound (NUS) is currently seen as a main component of follow-up of differentiated thyroid cancer (DTC) and is usually performed regardless of non-stimulated thyroglobulin (Tg) levels. The aim of this study is to determine whether there is a clinical benefit from such a routine NUS in DTC patients. METHODS: We performed a retrospective database study of 3176 cervical ultrasound exams performed in 773 patients between June 15, 1996 and July 1, 2012...

BACKGROUND: In the eighth edition of the AJCC staging system for differentiated thyroid carcinoma (DTC), minimal extrathyroidal extension (ETE) is no longer a determinant of T3 category. Instead, gross ETE invading only strap muscles has been designated as a new T3b category. The long-term prognosis of patients with DTC and gross ETE invading only strap muscles was investigated. METHODS: This was a retrospective analysis of patients who underwent thyroidectomy between 1996 and 2005...

Immune checkpoint inhibitor therapies targeting PD-L1/PD-1 have been shown to be effective in treating several types of human cancer. In papillary thyroid carcinoma (PTC), little is known about the expression of PD-L1/PD-1 in the tumor microenvironment or its potential correlation with BRAF V600E mutation status. In this study, we examined the expression of PD-L1, PD-1, and BRAF V600E in PTC by immunohistochemistry and investigated the clinical significance of expression status. We studied the expression of PD-L1, PD-1, and BRAF V600E by immunohistochemical staining in 110 cases of PTC with a diameter > 1 cm...

Differentiated thyroid cancer (DTC) is usually curable with surgery, radioactive iodine (RAI), and thyroid-stimulating hormone (TSH) suppression. However, local recurrence and/or distant metastases occur in approximately 15% of cases during follow-up, and nearly two-thirds of these patients will become RAI-refractory (RR-DTC) with a poor prognosis. This review focuses on the most challenging and rapidly evolving aspects of RR-DTC, and we discuss the considerable improvement in more accurately defining RR-DTC, more effective therapeutic strategies, and describe the diagnosis, pathogenesis, and future prospects of RR-DTC...

Metastases to cervical lymph node are fairly common in differentiated thyroid cancer. In iodine-refractory disease, the disease may persist in the thyroid bed, cervical lymph nodes, lungs, or the bones commonly. Retropharyngeal lymph nodal involvement in thyroid cancer is unusual and may even be the presenting complaint. We represent a case of iodine-refractory thyroid cancer with retropharyngeal lymph nodal involvement in addition to lung metastases.

Background: Preablative stimulated thyroglobulin (ps-Tg) is an important investigation in the follow-up of patients with Differentiated thyroid cancer(DTC) after surgery. Levels of ps-Tg >2-10 ng/ml have been suggested to predict metastasis to cervical and extracervical sites. There is still debate on the need for routine iodine whole-body scan (131 I WBS) in the management of low-to-intermediate-risk DTC patients. Objective: We analyzed our data of patients with DTC who underwent total thyroidectomy to discuss the predictability of ps-Tg on metastatic disease on the 131 I WBS...

Papillary thyroid carcinoma (PTC) has been increasing across the world with incomplete understanding of its pathogenesis. We aimed to investigate gene alterations and biomarkers contributing to PTC development. A total of five eligible microarray datasets including 94 PTC and 81 normal thyroid samples were included to identify gene expression signatures. Using integrative meta-analysis of expression data (INMEX) program, we identified a total of 2699 differentially expressed genes (DEGs) (1333 overexpressed and 1366 underexpressed genes) in PTC relative to normal thyroid samples...

BACKGROUND: Regional lymph node metastases (LNM) have prognostic significance in differentiated thyroid cancer (DTC). However, there was no distinction between N1a and N1b in the final staging classification in the eighth edition of the tumor-node-metastasis (TNM) staging system. This study aimed to evaluate the prognostic implication of N1b classification for predicting disease-specific survival (DSS) in DTC patients with stage I/II disease. METHODS: A total of 3089 patients with stage I/II DTC who underwent thyroid surgery between 1996 and 2005 were included...

Introduction  The rates of thyroid cancers are on a rise, especially well-differentiated thyroid cancers. This could be partly due to newer diagnostic modalities, like high-resolution ultrasound, that can pick up smaller lesions. Differentiated thyroid cancers with distant metastases are not common, and even rarer is the initial presentation with complaints not related to the neck. Objectives  The objective of this series was to study and report the unusual cases of patients with differentiated thyroid cancer with distant metastasis...
