BACKGROUND Insertion of drainage tubes at gastric cancer surgery could be useful for the prediction and management of postoperative complications. However, drains should be removed as soon as they are deemed unnecessary for various reasons. Amylase concentration of the drainage fluid following total gastrectomy for gastric cancer has been reported to be a(More)
BACKGROUND Tumor budding has been suggested to be a prognostic factor in various cancers but has never been studied in esophageal cancer. METHODS In this study, the microscopic finding of tumor budding in esophageal squamous cell carcinoma was correlated with outcome after esophagectomy. One hundred and thirty-six patients undergoing a curative(More)
BACKGROUND Various inflammation-based prognostic scores, including the Glasgow prognostic score (GPS), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), prognostic index (PI), and prognostic nutritional index (PNI), have been associated with survival in patients with several types of cancer. This study compared the ability of these(More)
BACKGROUND Identification of novel molecular biomarkers will improve the management of patients with gastric cancer (GC). Prenyl diphosphate synthase subunit 2 (PDSS2) is required for coenzyme Q10 biosynthesis and acts as a tumor suppressor; however, the role and regulatory mechanisms of PDSS2 in GC are not understood. The aim of this study was to determine(More)
Despite recent advances in surgical techniques including staple closure and ultrasonic devices, the reported incidence of postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP) remains high. Therefore, we devised a new strategy in which the pancreatic stump is enveloped with the elevated jejunum (EJ) by a modified Blumgart anastomotic(More)
BACKGROUND AND OBJECTIVES Pancreatic fistula (PF) and subsequent intra-abdominal abscess is a serious complication after gastrectomy for gastric cancer. The study aims to evaluate amylase concentration of drainage fluid (d-AMY) and serum C-reactive protein (CRP) as the predictive factors related to PF amounting to Clavien-Dindo (CD) grade III. METHODS 448(More)
BACKGROUND Epithelial-to-mesenchymal transition (EMT) is considered to play an important role in cancer invasion and metastasis. METHODS The mRNA levels of an epithelial marker (E-cadherin), mesenchymal marker (vimentin), and Zeb-1 were measured in 11 gastric cancer cell lines. Functional analysis was performed using Zeb-1 knockdown. EMT status of 116(More)
OBJECTIVE The purpose of this study was to evaluate the prognostic relevance of SMAD4 expression in pancreatic cancer. METHODS We analyzed the correlations between SMAD4 expression and clinicopathological parameters and outcome in 174 patients with pancreatic cancer. Specimens were also classified into subtypes reflecting epithelial-to-mesenchymal(More)
CXCR4, a chemokine receptor, is considered to be involved in the metastastic formation of various types of cancer and could influence survival. More recently, CXCR4 was reported to be associated with peritoneal metastasis in gastric cancer, and CXCL12, its ligand, as a prognostic determinant among gastric cancer of various stages. In order to more(More)
