BACKGROUND: The cysteinyl transfer RNA synthetase gene (CARS) is located on chromosome band 11p15.5, which is an important tumor-suppressor gene region. Mutations in CARS have been identified in many kinds of cancers; however, evidence for a relationship between genetic variants in CARS and gastric cancer at the population level is still lacking. Thus, we explored the association of variants in CARS with gastric cancer using a two-stage case-control strategy in Chinese. METHODS: We undertook a two-stage case-control study to investigate the association between polymorphisms in CARS and risk of gastric cancer with use of an Illumina Infinium(®) BeadChip and an ABI 7900 system...

BACKGROUND: Data concerning the long-term outcomes of endoscopic submucosal dissection (ESD) versus surgery for early gastric cancer (EGC) are limited. We aimed to compare the long-term outcomes of ESD and surgery for patients with EGC. METHODS: Data were reviewed from patients treated by ESD or surgery for EGC in 2005-2010. The primary outcome was overall survival (OS). Secondary outcomes were disease-specific survival (DSS), disease-free survival (DFS), recurrence-free survival (RFS), treatment-related complications, and hospital stay duration...

BACKGROUND: Although anthracycline-based triplets are one of the most widely used schedules to treat advanced gastric cancer (AGC), the benefit of including epirubicin in these therapeutic combinations remains unknown. This study aims to evaluate both the efficacy and tolerance of triplets with epirubicin vs. doublets with platinum-fluoropyrimidine in a national AGC registry. METHODS: Patients with AGC treated with polychemotherapy without trastuzumab at 28 hospitals in Spain between 2008 and 2016 were included...

BACKGROUND: Transcribed ultraconserved regions (T-UCRs) are a novel class of noncoding RNAs that are highly conserved among the orthologous regions in most vertebrates. It has been reported that T-UCRs have distinct signatures in human cancers. We previously discovered the downregulation of T-UCR expression in gastric cancer (GC), indicating that T-UCRs could play an important role in GC biology. Uc.160+, a T-UCR reported to be downregulated in human cancer, has not been examined in GC...

BACKGROUND: Some gastric adenomas may progress to adenocarcinoma in a short time, but others remain as adenoma for a long time. METHODS: Among 1138 cases diagnosed as adenoma by biopsy at Kure Medical Association Hospital between 1990 and 2010, 51 adenomas were enrolled. Of these, 28 adenomas (group A) were followed for 60 months or longer with no progression to adenocarcinoma within 60 months, and the other 23 adenomas (group B) were upgraded to carcinoma by consecutive biopsies performed within 1 year after the first biopsy...

BACKGROUND: Keratin 17 (KRT17) was shown to be an important molecular marker for predicting the carcinogenesis, progression, and prognosis of various cancer types. Our previous studies identified KRT17 as a possible biomarker for gastric cancer by gene microarray, with an elevated expression that occurred early during tumorigenesis and increased during tumor progression. Based on these findings, we aimed to investigate KRT17 biological functions in gastric adenocarcinoma and its possible use as a rational molecular target for anticancer therapy...

BACKGROUND: Papillary adenocarcinoma of the stomach has been treated according to the same endoscopic submucosal dissection (ESD) indication criteria as other differentiated-type adenocarcinomas. We aimed to compare lymph node metastasis (LNM) in patients with early gastric cancer (EGC) with papillary adenocarcinoma (EGC-P) with that in patients with EGC with nonpapillary adenocarcinoma (EGC-NP) and to consider the potential limitation of current ESD indication criteria in the treatment of EGC-P...

BACKGROUND: The E-cadherin, N-cadherin, and Snail genes are epithelial-mesenchymal transition (EMT)-inducible genes. Previous studies demonstrated that the expression of EMT markers in the primary tumor sites of gastric cancer correlates with tumor progression and prognosis. However, the clinical significance of the expression of these EMT markers in metastatic lymph nodes remains unclear. In the present study, we investigated the expression of these EMT markers in the primary tumor sites and metastatic lymph nodes...

BACKGROUND: Minimal residual disease of the peritoneum is challenging for early cancer detection in gastric cancer (GC). Utility of PCR amplification of cancer-derived DNA has been considered feasible due to its molecular stability, however such markers have never been available in GC clinics. We recently discovered cancer-specific methylation of CDO1 gene in GC, and investigated the clinical potential to detect the minimal residual disease. METHODS: One hundred and two GC patients were investigated for peritoneal fluid cytology test (CY), and detection level of the promoter DNA methylation of CDO1 gene was assessed by quantitative methylation specific PCR (Q-MSP) in the sediments (DNA CY)...

BACKGROUND: Gastric carcinoma with lymphoid stroma (GCLS) is characterized by undifferentiated carcinoma mixed with prominent lymphoid infiltration. GCLS has unique clinicopathological features and a better prognosis compared to other types of gastric cancer. We analyzed the clinicopathological features of early GCLS in relation to lymph node metastasis (LNM). METHODS: We performed a retrospective analysis of 241 patients diagnosed with GCLS confined to the mucosa or the submucosa between March 1998 and December 2015...
