BACKGROUND: The prognosis of metastatic gastric cancer (GC) remains dismal, with a median survival of 10 months. Historically, primary tumor resection was not thought to confer any survival benefit. Although high-level data exist guiding treatment of metastatic GC for patients in the East, no such data exist for Western patients despite inherent ethnic differences in GC biology. METHODS: The 2006-2012 National Cancer Database was queried for adult patients with metastatic gastric adenocarcinoma...

Helicobacter pylori infection causes chronic active gastritis that after many years of infection can develop into peptic ulceration or gastric adenocarcinoma. The bacterium is highly adapted to surviving in the gastric environment and a key adaptation is the virulence factor urease. Although widely postulated, the requirement of urease expression for persistent infection has not been elucidated experimentally as conventional urease knockout mutants are incapable of colonization. To overcome this constraint, conditional H...

BACKGROUND: Gastric cancer (GC) is the third leading cause of cancer death, and most patients represent metastatic phenotype at the time of diagnosis. Urokinase plasminogen activator (uPA) system is well known for its critical roles in cancer cells invasion since uPA/uPA receptor (uPAR) overexpresses in several cancers. Subsequently, suppression of uPA/uPAR gene expression improves patients overall survival and prevents cancer progression. OBJECTIVES: The aim of the current study was to investigate possible effects of live Lactobacillus reuteri as a probiotic in inhibition of GC cells proliferation and invasion...

BACKGROUND: Over the last two decades, intraperitoneal chemotherapy has been found to have activity for select subgroups of patients with carcinomatosis from colon, ovarian, appendiceal, and recently, gastric origins. However, there is little data to support an aggressive surgical approach of cytoreduction (debulking) and hyperthermic intraperitoneal perfusion with chemotherapy (HIPEC) for patients with gastric cancer and positive cytology or carcinomatosis. The morbidity and mortality rates of cytoreduction and HIPEC, in combination with gastrectomy, are significant and the survival rates of this approach may not extend beyond that of treatment with systemic chemotherapy...

Gastric cancer is one of the most common tumors of the digestive system. Here, analysis of the expression profiles of circular RNAs in advanced gastric adenocarcinoma and adjacent normal mucosa tissues revealed differential expression of 306 circular RNAs, among which 273 were predicted to exert regulatory effects on target microRNAs. The downstream pathway networks of circular RNA-microRNA were mapped and the node genes were identified. In particular, we found that the expression of hsa_circ_0058246 was elevated in tumor specimens of patients with poor clinical outcomes...

BACKGROUND: Solitary metastasis of a malignancy to the spleen is rare, particularly for gastric cancer. Only a few case reports have documented isolated splenic metastasis from early gastric cancer. We describe a case of splenic metastasis from early gastric cancer. CASE PRESENTATION: A 60-year-old man underwent a distal gastrectomy for early gastric cancer. It infiltrated the submucosa with pathological nodal involvement (pT1bN2M0, stage IIB). One year after the gastrectomy, an abdominal computed tomography scan showed a low-density lesion, 17 mm in diameter, at the upper pole of the spleen...

BACKGROUND: Venous thromboembolism (VTE) is an independent predictor of death among patients with cancer. Patients with gastric cancer (GC) are at higher risk for VTE when compared to other solid tumors, and if one considers its prevalence, GC may be responsible for one of the highest incidences of cancer-associated thrombosis. The impact of VTE on mortality is not well defined among patients with GC. AIM: The aim of this study is to measure the impact of VTE as independent predictor of GC mortality...

Increasing evidence suggests that the glutathione peroxidase 2 may actually play important roles in tumorigenesis and progression in various human cancers such as colorectal carcinomas and lung adenocarcinomas. However, the role of glutathione peroxidase 2 in gastric carcinoma remains to be determined. In this study, the expression and prognostic significance of glutathione peroxidase 2 in gastric carcinoma were investigated and the well-known prognostic factor Ki-67 labeling index was also assessed as positive control...

Gastric carcinoma (GC) is the fifth most common malignancy worldwide but the third leading cause of cancer death, and surgery remains the only curative treatment option. Prognosis of patients with liver metastases from gastric carcinoma (LMGC) is poor, and the optimal treatment of metastatic gastric cancer remains a matter of debate. In 2002, a 53-year-old male patient with GC and synchronous oligometastatic lesion in liver VIII segment underwent a total gastrectomy combined with metastasectomy. The pathologic diagnosis was stage IV gastric adenocarcinoma (pT3N2M1), which was treated with adjuvant chemotherapy (cisplatin, epirubicin, leucovorin, and 5-fluorouracil)...

The incidence of gastric and rectal carcinoids is increasing. This is probably due to endoscopic screening. The prognosis is primarily dependent upon tumor size, aggressiveness (pathology, Ki-67), metastatic disease and stage. However, neuroendocrine carcinoma usually behaves as an adenocarcinoma.

BACKGROUND: A significant proportion of patients never receive curative-intent surgery for resectable gastric cancer (GC). The primary aims of this study were to identify disparities and targetable risk factors associated with failure to operate in the context of national trends in surgical rates for resectable GC. METHODS: The National Cancer Database was used to identify patients with resectable GC (adenocarcinoma, clinical stage IA-IIIC, 2004-2013). Multivariate modeling was used to identify predictors of resection and to analyze the impact of surgery on overall survival (OS)...

Until now, no standard chemotherapy has been widely accepted for advanced gastric cancer (GC). The current research aimed to compare folinic acid, fluorouracil with irinotecan (mFOLFIRI) or with oxaliplatin (mFOLFOX7) as first-line treatments in patients with locally advanced GC in an open, randomized, phase II study. Previously untreated metastatic or recurrent GC patients with measurable disease received mFOLFIRI (arm A) or mFOLFOX7 (arm B) every 2 weeks. The defined second-line treatment was mFOLFOX7 for arm A and mFOLFIRI for arm B...

BACKGROUND/AIM: Helicobacter pylori is a pathogen that colonizes a majority of the world's population. Genetic diversity within the virulence genes of bacteria such as cagPAI and vacA may have a modified effect on the pathogenic potential of the bacteria. This study aimed to investigate which genes can be suggested as potentially related virulence factors for H. pylori-associated active chronic gastritis and stomach adenocarcinoma in the northwest of Iran and south of Turkey. MATERIALS AND METHODS: Formalin-fixed, paraffin-embedded stomach biopsy tissue samples were obtained from Iranian and Turkish patients from selected geographical regions...

Here, we report that it's feasible for imaging gastric adenocarcinoma mice model with prostate-specific membrane antigen (PSMA) targeting imaging agents, which could potentially provide an alternate and readily translational tool for managing gastric adenocarcinoma. DKFZ-PSMA-617, a PSMA targeting ligand reported recently, was chosen to be radio-labeled with nuclide 64Cu. 64Cu-PSMA-617 was radio-synthesized in high radio-chemical yield and specific activity up to 19.3 GBq/μmol. It showed good stability in vitro...

Importance: Small-bowel adenocarcinomas (SBAs) are rare cancers with a significantly lower incidence, later stage at diagnosis, and worse overall survival than other intestinal-derived cancers. To date, comprehensive genomic analysis of SBA is lacking. Objective: To perform in-depth genomic characterization of a large series of SBAs and other gastrointestinal tumors to draw comparisons and identify potentially clinically actionable alterations. Design, Setting, and Participants: Prospective analysis was performed of clinical samples from patients with SBA (n = 317), colorectal cancer (n = 6353), and gastric carcinoma (n = 889) collected between August 24, 2012, and February 3, 2016, using hybrid-capture-based genomic profiling, at the request of the individual treating physicians in the course of clinical care for the purpose of making therapy decisions...
