Ultrasonographic Thyroid Nodule Classification Using a Deep Convolutional Neural Network with Surgical Pathology.

Ultrasonography with fine-needle aspiration biopsy is commonly used to detect thyroid cancer. However, thyroid ultrasonography is prone to subjective interpretations and interobserver variabilities. The objective of this study was to develop a thyroid nodule classification system for ultrasonography using convolutional neural networks.

Postoperative Thyroid-Stimulating Hormone Levels Did Not Affect Recurrence after Thyroid Lobectomy in Patients with Papillary Thyroid Cancer.

Background: Thyroid-stimulating hormone (TSH) suppression is recommended for patients who undergo thyroidectomy for differentiated thyroid cancer (DTC). However, the impact of TSH suppression on clinical outcomes in low-risk DTC remains uncertain. Therefore, we investigated the effects of postoperative TSH levels on recurrence in patients with low-risk DTC after thyroid lobectomy.

Guidelines for the Surgical Management of Oral Cancer: Korean Society of Thyroid-Head and Neck Surgery.

Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to "surgical management of oral cancer" published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies.

Extent of surgery did not affect recurrence during 7-years follow-up in papillary thyroid cancer sized 1-4 cm: Preliminary results.

Objective: There is debate whether hemithyroidectomy is sufficient for patients with papillary thyroid cancer (PTC) sized 1-4 cm. Therefore, we investigated whether hemithyroidectomy affects recurrence rate compared with thyroidectomy in patients with PTC sized 1-4 cm.

Design: Retrospective observational study.

Guidelines for the Surgical Management of Laryngeal Cancer: Korean Society of Thyroid-Head and Neck Surgery.

Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to develop clinical practice guidelines for the surgical treatment of laryngeal cancer. This Task Force conducted a systematic search of the EMBASE, MEDLINE, Cochrane Library, and KoreaMed databases to identify relevant articles, using search terms selected according to the key questions. Evidence-based recommendations were then created on the basis of these articles.

Vitamin D level is not a predictor of hypocalcemia after total thyroidectomy.

Purpose: As the incidence of thyroid cancer has increased, hypocalcemia, a common complication of thyroid surgery, has become a serious problem. However, no definite predictor of postoperative hypocalcemia is known. In this study, our purpose was to investigate the potential role of vitamin D as a predictor of postoperative hypocalcemia.

Comparison of quality of life between open and endoscopic thyroidectomy for papillary thyroid cancer.

Background: Recently, various endoscopic thyroidectomy techniques have been introduced for cosmetic purposes. However, few reports have compared the quality of life (QOL) between post-endoscopic thyroidectomy and post-conventional open thyroidectomy. In this study, we investigated whether endoscopic thyroidectomy was comparable to conventional open thyroidectomy with respect to QOL.

Central lymph node metastasis in papillary thyroid microcarcinoma can be stratified according to the number, the size of metastatic foci, and the presence of desmoplasia.

Background: Lymph node (LN) metastasis is common in papillary thyroid microcarcinoma (PTMC). The aim of this study was to investigate the impact of LN metastasis and its risk stratification on PTMC recurrence.

Methods: We retrospectively reviewed the data of 336 patients with PTMC who underwent surgery from 2005 to 2006 at a single institution.

Preoperative localization and intraoperative parathyroid hormone assay in korean patients with primary hyperparathyroidism.

Background: The intraoperative parathyroid hormone (IOPTH) assay is widely used in patients with primary hyperparathyroidism (PHPT). We investigated the usefulness of the IOPTH assay in Korean patients with PHPT.

Methods: We retrospectively reviewed the data of 33 patients with PHPT who underwent parathyroidectomy.

Loss of ERβ expression in papillary thyroid carcinoma is associated with recurrence in young female.

Objectives: We investigated the expression of oestrogen receptors (ERs) in papillary thyroid cancers (PTCs) and evaluated their prognostic role.

Methods: We enrolled 81 female patients who underwent thyroid surgery and had a confirmed diagnosis of PTC between 01 January 1995 and 31 December 1996. Data on clinicopathologic parameters were obtained from patients' medical records.

Comparative study of a gasless transaxillary approach versus a bilateral axillo-breast approach for endoscopic thyroidectomy in a single institute.

Background: Gasless transaxillary approach (TA) and the bilateral axillo-breast approach (BABA) are 2 distinctive approaches for endoscopic thyroidectomy. The purpose of this study was to evaluate and compare these 2 procedures.

Methods: From May 2008 to July 2011, we performed endoscopic hemithyroidectomy via gasless TA (83 cases) and BABA (45 cases).

New endoscopic thyroidectomy via a unilateral axillo-breast approach with gas insufflation: Preliminary report.

Background: Invasiveness of endoscopic thyroidectomy has been in debate. The purpose of this study was to introduce new endoscopic thyroidectomy via a unilateral axillo-breast approach (UABA) with gas insufflation to lessen invasiveness.

Methods: We performed 68 cases of hemithyroidectomy via a UABA with gas insufflation from January to July 2011.

Role of adjuvant chemotherapy in malignant mucosal melanoma of the head and neck.

The objective of this study was to analyze the role of adjuvant chemotherapy and prognostic factors in malignant mucosal melanoma of the head and neck (HNMM). Thirty-two patients with mucosal melanoma of the head and neck who received local treatment with or without adjuvant chemotherapy were reviewed. Clinicopathologic parameters including anatomic sites, gender, age (60 vs.

Stereotactic body radiotherapy for refractory cervical lymph node recurrence of nonanaplastic thyroid cancer.

Objective: To investigate the feasibility and efficacy of stereotactic body radiotherapy as salvage treatment for cervical node recurrence from nonanaplastic thyroid cancer refractory to other modalities.

Study Design: Pilot study.

Setting: A single institution-based practice.

EGFR mutations and human papillomavirus in squamous cell carcinoma of tongue and tonsil.

This study was performed to determine the clinical significance of mutations in the EGFR (epidermal growth factor receptor) along with their association with human papillomavirus (HPV) infections in patients with squamous cell carcinoma of the head and neck (HNSCC). Exons 18-21 of the EGFR tyrosine kinase domain were sequenced and HPV typing was carried out using the HPV DNA chip in tissues obtained from patients with tongue and tonsil cancer. Univariate and multivariate analyses were used to identify the significant factors.
