PURPOSE: Stomach adenocarcinoma (STAD) has become the second main cause of cancer death around the world, and accumulated evidence has suggested that micro-RNAs (miRNAs) are likely to be served as indicator for diagnosis and prognosis in a variety of tumors. The purpose of this study was to discover the miRNAs acting as independent prognostic factors of STAD and to provide reference for the STAD diagnosis and prognosis. METHODS: In this study, we analyzed the clinical data collected from 393 STAD cases of the Cancer Genome Atlas (TCGA;USA) and the expression data of 1881 miRNAs to screen miRNAs that were associated with STAD via Cox regression univariate analysis and those miRNAs with independent effect on the prognosis of STAD via Cox regression multivariate analysis...

PURPOSE: The contradictory long-term results following D2 lymphadenectomy have revealed the necessity for a more tailored lymphadenectomy in cases of gastric cancer. Among the patients who had undergone a modified D2 lymphadenectomy for gastric cancer, we further analyzed the subgroup in which histologically and immunohistochemically solitary lymph node metastases were detected. Classifying the primary tumors as towards to the lesser and towards to the grater curvature, we propose possible routes of lymphatic spread and possible clinical implications...

Germline mutations in CDH1, the gene coding for the E-cadherin adhesion protein, are known to cause hereditary diffuse gastric cancer. We identified a new truncating germline mutation (p.Asp538Thrfs*19) in exon 11 of the CDH1 gene in a 41-year-old male with a diffuse gastric cancer. Although he had no parental history of gastric cancer, the co-segregation study in the family detected the same mutation in his healthy 31-year-old brother. The mutation affects one of the extracellular repeat (CAD repeats) domains which is essential for the homophilic binding specificity that directs "E-cadherin" to bind with itself each others...

Pulmonary squamous cell carcinoma is the second most common non-small cell malignancy of the lung. It commonly metastasizes to the adrenal glands, bone, liver, brain, and kidneys. Most occurrences of metastatic squamous cell carcinoma involving the gastrointestinal tract originate from primary lung tumors. Metastasis to the duodenum, however, is exceedingly rare, with very few cases of stomach or duodenal involvement described in the literature. We report the case of a patient with stage IV pulmonary squamous cell carcinoma metastasizing to the duodenum with an uncommon presentation to add to the paucity of literature available regarding this rare finding...

BACKGROUND: Radiotherapy for pancreatic cancer has two major challenges: (I) the tumor is adjacent to several critical organs and, (II) the mobility of both, the tumor and its surrounding organs at risk (OARs). A treatment planning study simulating stereotactic body radiation therapy (SBRT) for pancreatic tumors with both the internal target volume (ITV) concept and the tumor tracking approach was performed. The two respiratory motion-management techniques were compared in terms of doses to the target volume and organs at risk...

Immune evasion is a well-recognized hallmark of cancer and recent studies with immunotherapy agents have suggested that tumors with increased numbers of neoantigens elicit greater immune responses. We hypothesized that the immune system presents a common selective pressure on high mutation burden tumors and therefore immune evasion mutations would be enriched in high mutation burden tumors. The JAK family of kinases is required for the signaling of a host of immune modulators in tumor, stromal, and immune cells...

IMP3 is an RNA binding protein required for ribosomal RNA processing, which has been suggested to be a prognostic marker in a large variety of human types of cancer. However, available data on the prevalence of IMP3 expression are largely discrepant. To systematically investigate the epidemiology and clinical relevance of IMP3 expression in human cancers we employed a two-step tissue microarrays (TMAs) approach. First, a normal tissue TMA and a multi-tumor TMA were analyzed for immunohistochemically detectable expression of IMP3 in 76 different normal tissue types and 3889 cancer samples from 95 different tumor categories...

A woman in her 70s was diagnosed with a protruding mucosa-associated lymphoid tissue (MALT) lymphoma during a secondary health examination. After eradication of Helicobacter pylori, a biopsy revealed gastric follicular lymphoma (FL) and the lesion was still protruding one year later. (18)F-fluorodeoxyglucose positron emission tomography showed focal nodular hypermetabolic activity, suggesting that FL may have transformed into a diffuse large B-cell lymphoma. Upper gastrointestinal endoscopy, colonoscopy, and capsule endoscopy showed no other lesions in the gastrointestinal tract, and bone marrow biopsy showed no permeation into the marrow...

BACKGROUND: Emerging evidence suggested that miRNAs can function as oncogenes or tumor suppressors by regulating downstream target genes. miR-324-3p has been reported to function in several carcinomas, but its role in gastric cancer (GC) is still unknown. This study aims to explore the effects of miR-324-3p on the development of GC. METHODS: Expression of miR-324-3p was examined in GC cells and tissues by qRT-PCR. Effects of miR-324-3p on GC cells were evaluated by cell vitality assay, colony formation assay, cell migration assay, and flow cytometric assay...

BACKGROUND: Current endoscopic full-thickness resection (EFTR) methods produce transmural communication and expose the tumor to the peritoneum. An EFTR method with a simple suturing technique that does not expose the gastric mucosa to the peritoneum (non-exposure simple suturing, NESS) was recently developed. To date, there have been no prospective studies that compare EFTR with laparoscopic wedge resection in human or animal. The aim of this study was to compare outcomes between NESS-EFTR and laparoscopic wedge resection (LWR) using the linear staplers in a randomized animal study...

Lymphomas are solid tumors of the lymphatic system and these are divided into Hodgkin's and non-Hodgkin lymphoma. Non-Hodgkin tumors may originate from non-nodal tissues such as the gastrointestinal tract and they are considered primary when extranodal involvement is equal to or greater than 75% according to the nodal involvement. Extranodal gastrointestinal lymphomas represent 1% to 4% of tumors of the digestive tract, and 10 to 15% of all non-Hodgkin lymphomas. The stomach is the most common extranodal lymphomas site...
