BACKGROUND Pancreatic neuroendocrine tumors (PanNETs) are malignant endocrine neoplasms that present diverse clinical behaviors. Therefore, identification of biomarkers of PanNETs is important for stratification of the prognosis of PanNET patients. Recently, cytokeratin 19 (CK19) and KIT expression were reported to have prognostic significance in PanNET patients. METHODS To identify their pro...
BACKGROUND To identify prognostic factors in patients with parotid gland carcinomas who were treated at the Princess Margaret Hospital. METHODS Clinical outcome of two hundred fifteen patients with malignancies of the parotid gland was evaluated over a 16-year period. RESULTS Two-hundred-fifteen patients with adenoid cystic carcinoma (n = 20), adenocarcinoma (n = 19), acinic cell carcinoma ...
INTRODUCTION Whipple's Pancreaticoduodenectomy has increasingly been used as an appropriate resectional procedure for tumors of the periampullary region which are pancreatic, periampullary, ampullary and biliary tumors. Our aim was to study the distribution and histopathologic features of these tumors and to examine local trends of periampullary neoplasms resected with a PD. METHODS A descrip...
Breast cancer incidence is lower and survival is longer in Asian women residing in Japan, China, or the Philippines than Caucasian women residing in the United States. Phytoestrogen intake has been examined as a possible reason for the disparity in breast cancer incidence and survival. This study examined the association between phytoestrogen intake prior to diagnosis of breast cancer and indic...
BACKGROUND Vascular endothelial growth factor-C (VEGF-C) is the main inducer of lymphangiogenesis. VEGF-C overexpression is associated with lymphovascular tumor cell invasion, an increased rate of lymph node metastasis and adverse prognosis in various human cancers. However, little is known about the upstream inducers of VEGF-C expression. Recent studies have shown that human epidermal growth f...
The neutrophil-to-lymphocyte ratio (NLR) is an inflammation marker that has prognostic value for various tumors, but its prognostic value in urothelial carcinoma (UC) remains controversial. This meta-analysis investigated the prognostic value of NLR in UC. A systematic search was performed on PubMed, ISI Web of Science, and Embase for studies focusing on the association between NLR and clinical...
PURPOSE The negative sentinel lymph node (SLN) biopsy avoids conventional axillary dissection in patients with breast cancer with clinically negative axilla. Despite negative SLN, there is a risk of leaving involved non-SLN behind in the axilla. We investigated the predictive power of tumor characteristics for non-SLN metastasis. METHODS Lymphatic mapping with blue dye method for SLN biopsy a...
