BACKGROUND AND OBJECTIVES Phyllodes tumors (PTs) are uncommon biphasic breast tumors that usually occur in adult females. They are composed of a benign epithelial component and a cellular, spindle cell stroma forming a leaf-like structure. No one morphologic finding is reliable in predicting the clinical behavior of the tumor. The purpose of this study was(More)
AIMS We investigated the relationship between serum leptin concentrations and polymorphism of the leptin receptor gene and breast cancer. METHODS Serum leptin concentrations were measured by enzyme-linked immunosorbent assay in 47 women with invasive breast cancer compared with 41 age-matched controls without cancer. Genomic DNA was extracted from(More)
BACKGROUND AND OBJECTIVES Inflammation has been implicated in the initiation and progression of thyroid cancer. Neutrophil-to-lymphocyte ratio (NLR) is a simple index of systemic inflammatory response, and has been shown to be a prognostic indicator in some types of cancer. The aim of this study was to examine the relationship between NLR and(More)
Patients with hereditary pheochromocytoma are at risk of the development of bilateral disease. Partial adrenalectomy can preserve adrenal function to avoid the morbidity associated with medical adrenal replacement. Here, we report a multimedia case study of synchronous bilateral partial adrenalectomy by the laparoscopic approach. A 13-year-old patient with(More)
The incidence of thyroid cancer has remarkably increased in recent years. Epidemiologic data suggest that obesity is associated with an increased incidence of several types of malignancies, including thyroid cancer. Leptin, an adipocyte-derived cytokine, has been shown to be involved in cancer development and progression. We previously demonstrated that(More)
Preoperative detection of vocal cord palsy is important in thyroid and parathyroid surgery. However, routine fiberoptic laryngoscopy may bring patients unnecessary discomfort. The aim of this study was to determine the feasibility of using surgeon-performed ultrasonography (US) as a screening tool for preoperative assessment of vocal cord movement. In the(More)
BACKGROUND The Thyroid Imaging Reporting and Data System (TI-RADS) was proposed based on a scheme similar to Breast Imaging Reporting and Data System (BI-RADS) lexicon used in breast lesions. The purpose of this study was to evaluate its interobserver variability and accuracy. METHODS We included 498 nodules in 437 patients undergoing thyroidectomy. Two(More)
OBJECTIVES Perchlorate, nitrate, and thiocyanate are well-known inhibitors of the sodium-iodide symporter and may disrupt thyroid function. This exploratory study investigated the association among urinary perchlorate, nitrate, and thiocyanate concentrations and parathyroid hormone (PTH) levels in the general U.S. population. METHODS We analyzed data on(More)
Phyllodes tumors of the breast are uncommon, and it is difficult to predict biologic behavior based on clinicopathologic features. Despite the wealth of data on the factors to predict recurrence, little is known about the impact of treatment refinements. This study seeks to define changes in patient characteristics, histopathologic parameters, and outcome(More)
Laparoscopic cholecystectomy in elderly patients has been linked to higher complication rates and longer lengths of stay. The purpose of this study was to identify risk factors associated with prolonged postoperative hospitalization in elderly patients undergoing laparoscopic cholecystectomy. The records of 287 patients aged 65 years or older, who underwent(More)
