PURPOSE The ARTIST (Adjuvant Chemoradiation Therapy in Stomach Cancer) trial was the first study to our knowledge to investigate the role of postoperative chemoradiotherapy therapy in patients with curatively resected gastric cancer with D2 lymph node dissection. This trial was designed to compare postoperative treatment with capecitabine plus cisplatin(More)
OBJECTIVE An accurate assessment of a potential lymph node metastasis is an important issue for the appropriate treatment of early gastric cancer. Minimizing the amount of invasive procedures used in cancer treatment is critical for improving the patient's quality of life. Therefore, this study analyzed the predictive risk factors for a lymph node(More)
BACKGROUND & AIMS Lymphoepithelioma-like carcinoma (LELC) is a rare subtype of gastric carcinoma (GC) with a better survival rate than other GCs; most cases of LELC are associated with Epstein-Barr virus (EBV) infection. We investigated whether the survival advantage of LELC is related to the EBV infection itself or to associated inflammatory immune(More)
BACKGROUND Laparoscopic-assisted distal gastrectomy (LADG) is a treatment method for patients with early gastric cancer; however, single or reduced port LADG has been rarely reported. This study aimed to compare surgical outcomes of patients with gastric cancer undergoing reduced port totally laparoscopic distal gastrectomy (duet TLDG) to those of patients(More)
PURPOSE In order to improve the likelihood of curative and safe gastric surgery, this study investigated the clinical features and surgical outcomes of gastric cancer with a synchronous cancer. PATIENTS AND METHODS The clinicopathological data of 10,090 gastric cancer patients at Samsung Medical Center from September 1994 to December 2006 were(More)
In this paper, we present a restricted temporal decomposition method for LSF parameters. The event vectors estimated by this method preserve the ordering property of LSF parameters so that they can be quantized efficiently. Experimental results show that interpolated LSF parameters can be quantized transparently at the rate of 753 bps. We also design a LPC(More)
BACKGROUND Surgical results including postoperative complications, prognoses, body weight changes, and nutritional statuses were compared in patients with early gastric cancer in the upper third of the stomach who were treated by total gastrectomy or proximal gastrectomy. METHODS The authors reviewed clinicopathologic features, postoperative(More)
Gastric cancer, a leading cause of cancer-related deaths, is a heterogeneous disease. We aim to establish clinically relevant molecular subtypes that would encompass this heterogeneity and provide useful clinical information. We use gene expression data to describe four molecular subtypes linked to distinct patterns of molecular alterations, disease(More)
Extracellular nucleotides regulate renal ion transport. With the use of in vitro perfusion and [Ca(2+)](i) imaging, this study investigated whether mouse and rabbit cortical collecting ducts (CCD) respond to luminal nucleotides. In mouse CCD, luminal ATP (EC(50): 10 microM) and UTP (EC(50): 9.7 microM) increased [Ca(2+)](i) with an initial peak and a(More)
Identification of critical genes which play pivotal roles in controlling tumor growth and survival will establish the basis for developing therapeutic targets. With the aim of establishing personalized medicine for treatment of solid tumors, we focused on MET amplification in gastric cancer patients, given the extreme sensitivity to c-Met inhibitor in MET(More)
