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)
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)
The aims of this study are to evaluate and compare the accuracies of isotropic multi-detector row CT (MDCT) including multiplanar reconstruction (MPR) images for preoperative staging of endoscopically diagnosed early gastric cancer (eEGC) and advanced gastric cancer (eAGC). One hundred and five patients with endoscopically proven gastric cancer underwent(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)
BACKGROUND Mesenchymal stem cells (MSCs), also known as multipotent progenitor cells, release several factors that support cell survival and enhance wound healing. We hypothesized that MSC-secreted molecules would induce a trophic effect in pancreatic islet culture conditions. METHODS Pancreatic islets were co-cultured with MSCs, and ADP/ATP ratios,(More)
The establishment of better selection criteria for identifying sub-populations that may benefit from treatment is a key aspect of the development and success of targeted therapy. To investigate methods for assessing MET overexpression in gastric cancer, we conducted immunohistochemistry using a new anti-Total MET monoclonal antibody in a single-institution(More)
BACKGROUND AND OBJECTIVES The correlation between perioperative CEA, CA 19-9, and CA 72-4 and recurrence of gastric cancer has not been clarified. The aim of this study was to investigate the relationships between perioperative CEA, CA 19-9, and CA 72-4 and recurrence of gastric cancer. METHODS We retrospectively analyzed the relationships between the(More)
Gastric cancer (GC) is the second most common cause of cancer-related deaths. It is known to be a heterogeneous disease with several molecular and histological subtypes. Here we perform whole-genome sequencing of 49 GCs with diffuse (N=31) and intestinal (N=18) histological subtypes and identify three mutational signatures, impacting TpT, CpG and TpCp[A/T](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)
