OBJECTIVE: To investigate the feasibility and necessity of endoscopic thyroidectomy with central lymph node dissection via the combined breast and trans-oral approaches. METHODS: Six patients with papillary thyroid carcinoma who underwent endoscopic total thyroidectomy with central node dissection via combined breast and trans-oral approaches from November 2014 to January 2015 in Zhongshan Hospital, Xiamen University, were analyzed. RESULTS: After completion of endoscopic central lymph node dissection via the traditional breast approach, eight pieces of lymph nodes could still be dissected via the trans-oral approach...

A woman in her 60s presented with a recurrent lymph node metastasis from a papillary thyroid carcinoma in the right parapharyngeal space. She had already undergone total thyroidectomy, five resections for cervical lymph node metastases, and right carotid rebuilding. Surgical resection of the current metastasis was impossible. (131)I-radioiodine therapy (RIT) with 3.7 GBq (131)I was not effective; therefore, stereotactic radiation therapy (SRT) using a CyberKnife radiotherapy system was scheduled. The prescription dose was 21 Gy, and a dose covering 95% of the planning target volume (PTV) in three fractions was administered...

The clinical data of 20 cases of patients with MTC confirmed by the clinical surgery were retrospectively analyzed. And the high-frequency ultrasound features were analyzed and compared with the pathological characteristics. There were 16 cases with tumor invasion into one side of the thyroid gland; 17 cases with tumor in the middle-upper pole of the thyroid gland...

BACKGROUND AND AIMS: miR-199a-3p may play an important role in tumour inhibition. The aim of the present study was to determine any link between miR-199a-3p expression in thyroid tissues and clinicopathologic features, as well as to assess potential usefulness of miR-199a-3p in prediction for invasion and metastasis of papillary thyroid carcinoma (PTC). METHODS: A total of 188 tissue samples (136 PTCs, 52 normal thyroid tissue) were collected. We measured the levels of miR-199a-3p with quantitative reverse-transcriptase PCR (RT-qPCR) in all subjects...

BACKGROUND The aim of this study was to evaluate the value of semiquantitative analysis (SQA) of 99mTc-MIBI imaging in predicting early-stage cervical lymph node metastasis (CLNM) in thyroid carcinoma (TC). MATERIAL AND METHODS TC patients (n =106) undergoing surgical resection and histopathological examination were enrolled. All patients received 99mTc-MIBI imaging prior to surgery. P-glycoprotein (P-gp) expression was detected by PT-PCR and immunohistochemistry. With pathological results as the criterion standard, the diagnostic efficiency of 99mTc-MIBI imaging in predicting early-stage CLNM was evaluated...

Papillary thyroid carcinoma (PTC) is a heterogeneous tumor with various histological and molecular subtypes. EHD2 is involved in endocytosis and endosomal recycling. This study aimed to investigate the prognostic significance of EHD2 expression in PTC and develop a new model for predicting persistent/recurrent disease after thyroidectomy. Pathologic slides of 512 consecutive patients with PTC ≥ 1 cm were retrospectively reviewed. BRAF mutation analysis and immunohistochemistry for EHD2 were performed. Clinical significance of EHD2 mRNA expression was analyzed in 388 PTC patients using The Cancer Genome Atlas dataset...

A poor papillary thyroid cancer (PTC) prognosis is strongly associated with the BRAF V600E mutation. During tumor progression, levels of the high mobility group box 1 (HMGB1) protein are often dysregulated. Results herein demonstrate that HMGB1 protein levels differ between tumor and adjacent non-tumor tissue and that HMGB1 mRNA levels were higher in wild-type BRAF PTC tissues than in BRAF V600E PTC tissues (2-△Ct 0.31 ± 0.25 vs. 0.16 ± 0.12; P < 0.05). HMGB1 protein levels also differed in the same manner (wild-type BRAF PTC tissues 0...

Background. High-resolution ultrasonography and the ability to perform fine-needle aspiration biopsy even for nodules smaller than three millimeters have considerably increased the detection rate of thyroid micropapillary carcinoma (TMPC). Despite favorable prognosis, the prevalence of cervical lymph node metastases in patients with TMPC is approximately 30%. Aim. In this study, we aimed to determine the central lymph node metastasis rate and its relation to the characteristics of the tumor. Methods. One hundred nine patients who underwent surgery due to TMPC between December 2009 and January 2014 were analyzed retrospectively...

OBJECTIVE: We assessed the associations between FDG uptake in primary papillary thyroid carcinomas (PTCs) and clinicopathological features, including the BRAF V600E mutation, using quantitative and qualitative analyses of preoperative PET/CT data. DESIGN AND PATIENTS: This was a retrospective review of 106 patients with PTC who underwent PET/CT scans between February 2009 and January 2011 before undergoing total thyroidectomy. Data collected from surgical specimens were compared with FDG uptake in the primary tumour using quantitative and qualitative analyses of preoperative PET/CT data...

The aim of this study was to investigate the correlation between elastography and histologic characteristics including fibrosis and calcification. We also wanted to investigate whether other clinicopathologic indexes influence the strain ratio (SR) of papillary thyroid carcinomas (PTCs). We retrospectively reviewed 126 papillary thyroid carcinomas (PTCs) from 103 patients who underwent ultrasonography and elastography before surgery. The histologic characteristics and clinicopathologic indexes were compared with the SR of ultrasound elastography (UE)...

Context: The A883F germline mutation of the REarranged during Transfection proto-oncogene causes multiple endocrine neoplasia 2B. In the revised American Thyroid Association (ATA) guidelines for the management of medullary thyroid carcinoma (MTC) the A883F mutation has been reclassified from the highest to high risk level, although no well-defined risk profile for this mutation exists. Objective: To create a risk profile for the A883F mutation for appropriate classification in the ATA risk levels...

Objective: To investigate the value of jugulo-omohyoid lymph nodes (JOHLN) in predicting occult lateral cervical lymph node metastasis in patients with papillary thyroid carcinoma (PTC). Methods: The clinicopathological data of 136 out of 2 100 PTC patients, who had a high risk of lateral neck lymph node metastasis and treated by us from January 2010 to December 2015, were retrospectively analyzed. Super selective neck dissection (SSND, level Ⅲ and Ⅳ)was performed and JOHLNs were sent for frozen section in all the 136 cases...

BACKGROUND: Clear-cell carcinoma of the thyroid has been regarded as a variant of follicular (FTC) or papillary (PTC) thyroid carcinoma. Twenty-one primary thyroid carcinomas with clear-cell features, diagnosed in 20 patients (12 female) were identified between 1992 and 2012 (0.5% of in-house thyroid carcinomas). METHODS: Hematoxylin and eosin slides were reviewed. SNaPshot multigene mutational analysis and a translocation panel were successfully performed on 15 of these cases...

Nonanaplastic follicular cell-derived thyroid carcinoma (NAFCTC) includes differentiated- (DTC) and poorly differentiated thyroid carcinoma (PDTC). DTC has an excellent prognosis, while PDTC is situated between DTC and anaplastic carcinomas. Short-term studies suggest that PDTC patients diagnosed only on tumor necrosis and/or mitosis have a prognosis similar to those diagnosed according to the TURIN proposal. The purpose of this study was to evaluate prognosis for NAFCTC based on long-term follow-up illuminating the significance of tumor necrosis and mitosis...

BACKGROUND: Prognostic factors are essential for risk stratification in patients with differentiated thyroid carcinoma (DTC). The role of stimulated postoperative thyroglobulin (sPOTg) has been well established in adult DTC population, but it remains unclear in children and adolescents. This study aimed to evaluate potential prognostic factors in children and adolescents with DTC, with special emphasis on sPOTg analysis. METHODS: Individuals aged ≤18 years at diagnosis were selected from a cohort of DTC patients attending the thyroid clinic of a tertiary university-based hospital...

PURPOSE: Papillary thyroid carcinoma (PTC) arising from the pyramidal lobe is rare; therefore, clinicopathologic evaluation is lacking. In addition, the rate of occult malignancy in the pyramidal lobe after thyroid surgery is unclear. This study is to evaluate the clinical characteristics of PTCs that involve the pyramidal lobe.
