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)
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)
BACKGROUND Somatic BRAF mutation is frequently observed in papillary thyroid carcinoma (PTC). Recent evidence suggests that PTCs are heterogeneous tumors containing a subclonal or oligoclonal occurrence of BRAF mutation. Conflicting results have been reported concerning the prognostic significance of the mutant allele frequency. Our present aim was to(More)
BACKGROUND 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(More)
We investigated the time it took to develop fatty liver and changes in serum aspartate aminotransferase and alanine aminotransferase levels in patients with breast cancer treated with adjuvant tamoxifen. Liver sonography to detect fatty liver and measurement of serum aspartate and alanine aminotransferase levels were performed regularly for patients with(More)
BACKGROUND Aluminum overload and accumulation in tissues may lead to skeletal, hematological, and neurological toxicity. The aim of this study was to assess the effects of serum aluminum levels on presentations, postoperative recovery, and symptom improvement in patients undergoing parathyroidectomy for secondary hyperparathyroidism. METHODS From 2008 to(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)
BACKGROUND Epidemiologic studies have shown that obesity is associated with an increased risk of thyroid cancer. Leptin, an adipocyte-derived cytokine, can act as a growth factor on certain normal and transformed cells. Aberrant expression of leptin or leptin receptor has been detected in some types of cancer. The aim of this study is to determine(More)
Local anesthetics are frequently used in fine-needle aspiration of thyroid lesions and locoregional control of persistent or recurrent thyroid cancer. Recent evidence suggests that local anesthetics have a broad spectrum of effects including inhibition of cell proliferation and induction of apoptosis in neuronal and other types of cells. In this study, we(More)
The frequent association of stromal tumors with neurofobromatosis raises high suspicion of a possible correlation between the two entities. The aim of this study was to analyze clinicopathologic features of patients with concomitant neurofibromatosis and gastrointestinal stromal tumors and to discuss the molecular basis for their possible pathogenesis.(More)
