REVIEW
Zhanwei Zhao, Zifang Yin, Qingchuan Zhao
The associations between red and processed meat consumption and gastric cancer risk have remained inconclusive. We performed a systematic review and meta-analysis to analyze these associations. We searched PubMed and EMBASE to identify studies published from inception through October 2016. Subtype analyses of gastric cancer (gastric cardia adenocarcinoma and gastric non-cardiac adenocarcinoma) and dose-response analyses were performed. We finally selected 42 eligible studies. The summary relative risks of highest versus lowest consumption were positive for case-control studies with 1...

INTRODUCTION: Metastasis is a leading cause of cancer-related-deaths worldwide. Recently, cancer stem cells (CSCs) have been believed to be responsible for tumor initiation and metastasis, but till now, difference of cellular features and behaviors between CSCs from tumor tissues (TCSCs) and circulation (CCSCs) remains largely unknown, which hinders the progression of targeted therapies for metastasis. METHODS AND RESULTS: Here, we provide the features of circulating gastric cancer stem cells (CGCSCs) isolated from human gastric adenocarcinoma...

Gastric adenocarcinoma (GAC) is a common cause of cancer-related death worldwide. GAC can be classified as intestinal or diffuse. Intestinal type cancers are common and reported to have a better prognosis compared to diffuse cancers. Studies have shown the presence and amount of tumor budding in intestinal carcinomas of the colon and esophagus to predict nodal metastasis and recurrence. Our aim is to determine if tumor budding in intestinal type GAC correlates with prognostic features. One hundred four patients treated with primary surgical excision between 1999-2013 were identified...

Gastric cancer, a leading worldwide cause of cancer mortality, shows high geographic and ethnic variation in incidence rates, which are highest in East Asia. The anatomic locations and clinical behavior also differ by geography, leading to the controversial idea that Eastern and Western forms of the disease are distinct. In view of these differences, we investigated whether gastric cancers from Eastern and Western patients show distinct genomic profiles. We used high-density profiling of somatic copy-number aberrations to analyze the largest collection to date of gastric adenocarcinomas and utilized genotyping data to rigorously annotate ethnic status...

Esophagogastric junction (EGJ) adenocarcinoma has been on the increase in Western countries. However, in Asian countries, data on the incidence of EGJ adenocarcinoma are evidently lacking. In the present review, we focus on the current clinical situation of EGJ adenocarcinoma in three Asian countries: Japan, Hong Kong, and Malaysia. The incidence of EGJ adenocarcinoma has been reported to be gradually increasing in Malaysia and Japan, whereas it has stabilized in Hong Kong. However, the number of cases in these countries is comparatively low compared with Western countries...

Siewert's classification of adenocarcinoma of the esophagogastric junction (EGJ) classifies tumors anatomically for determining the appropriate surgical technique. According to this classification, a type II tumor, true carcinoma of the cardia, is defined as a cancer within 1 cm proximal to 2 cm distal of the EGJ. Histological analysis indicates that the cardiac gland is present with a high degree of frequency between 1-2 cm to the gastric side and 1-2 cm to the esophageal side of the EGJ, which means that this zone can be considered as neither the stomach nor the esophagus but rather as a third zone known as the 'EGJ zone'...

BACKGROUND AND AIM: Western studies have suggested two distinct etiologies of esophagogastric junction (EGJ) cancer: Helicobacter pylori-associated atrophic gastritis and non-atrophic gastric mucosa resembling esophageal adenocarcinoma. The present study investigated whether endoscopic gastric mucosal atrophy can distinguish between these two types of EGJ adenocarcinoma. METHODS: Data were collected from patients with Siewert type II, T1 EGJ adenocarcinoma who underwent endoscopic or surgical resection at eight Japanese institutions in 2010-2015...

Gastric metastasis from ovarian cancer is exceptionally rare and generally occurs in advanced stages. A 71-year-old woman presented with a solitary gastric submucosal mass 8 years after the diagnosis of a stage IA ovarian serous adenocarcinoma. Endoscopy showed a tumor covered with normal gastric mucosa. Initially, a gastrointestinal stromal tumor was suspected, but biopsy revealed a histology of invasive micropapillary carcinoma, similar to the histological findings of the previously resected ovarian tumor...

BACKGROUND: The urokinase plasminogen activation (uPA) system is a crucial pathway for tumour invasion and establishment of metastasis. Although there is good evidence that uPA system expression is a clinically relevant biomarker in some solid tumours, its role in gastroesophageal cancer is uncertain. RESULTS: We identified 22 studies encompassing 1966 patients which fulfilled the inclusion criteria. uPA, uPAR, or PAI-1 expression is significantly associated with high risk clinicopathological features...

BACKGROUND: 5-Aminolevulinic acid is a precursor of photosensitizing protoporphyrin IX and has been applied for photodynamic diagnosis of brain and bladder tumors with few side effects. Although most upper gastrointestinal tumors can be detected during photodynamic diagnosis, some tumors containing signet-ring cells cannot be visualized. Here, we aimed to assess whether proteins involved in the absorbance, activation, and turnover of protoporphyrin IX altered the fluorescence signal in gastric cancer...

Gastric cancer including gastro-esophageal junction adenocarcinomas are most challenging and deadly cancers of the gastrointestinal tract. Gastric cancer has a fatality-to-case ratio of 0.66, translating that nearly two thirds of newly diagnosed patients will have disseminated disease and in need of systemic therapy (1). Advanced gastric adenocarcinoma (AGC) is a heterogenous disease with differences in geographical distribution, histopathology, and molecular subtypes. Fluoropyrimidines (5-FU, S-1, and capecitabine), platinum compounds (cisplatin, oxaliplatin), taxanes (paclitaxel, docetaxel), and the topoisomerase inhibitory irinotecan are active drugs against AGC...

INTRODUCTION: Multiple primary neoplasms are relatively rare, but their incidence has increased because of aging and improvements in diagnostic imaging. PRESENTATION OF CASE: A 67-year-old man presented with epigastric pain. On upper gastrointestinal endoscopy, an ulcer was seen at the gastric angle, and biopsy showed moderately differentiated adenocarcinoma (AC). Colonoscopy demonstrated a 15-mm lesion in the sigmoid colon and a submucosal lesion in the lower rectum...

Chronic Helicobacter pylori ( H. pylori) infection is a major gastric adenocarcinoma (GA) risk factor. GA disproportionately affects U.S. Hispanics compared with non-Hispanic Whites (NHWs). Since H. pylori infection studies in Hispanics are few, infection rates in Hispanic and NHW men in Bexar County were compared, and relationships with ethnicity and obesity examined. Age- and zip code-matched participants from a community-dwelling cohort were randomly selected. Sera from 284 men were analyzed by enzyme immunoassay for H...

A 59-year-old man was referred to the Kochi Medical School Hospital due to left shoulder pain. Physical examination revealed a nodular, painful mass lesion in the subcutaneous tissue of the right chest wall, with a diameter of ~2 cm. Esophagogastroduodenoscopy revealed a large ulcerated tumor in the lower gastric body near the lesser curvature, and biopsy specimens of the gastric and humeral lesions revealed poorly differentiated adenocarcinoma. Abdominal computed tomography revealed multiple low-density lesions in the liver and a well-defined, 2...

We report the case of a 73-year-old female who was diagnosed with advanced gastric cancer. Esophagogastroduodenoscopy was used to diagnose Borrmann type 3 advanced gastric cancer located at the gastric antrum. A biopsy revealed poorly differentiated adenocarcinoma. Abdominopelvic computed tomography (CT) and (18)F-fluorodeoxyglucose positron emission tomography-CT (FDG-PET-CT) scans demonstrated multiple lymph node metastases, including the para-aortic lymph nodes. Systemic chemotherapy with 5-fluoruracil (5-FU), oxaliplatin, and leucovorin (FOLFOX) was initiated...

Acanthosis nigricans (AN) is a dermatopathy associated with insulin-resistance, drugs, endocrine disorders, chromosomal abnormalities (benign AN), and neoplasia (malignant AN). Malignant AN (MAN) is a rare paraneoplastic skin syndrome most commonly associated with gastric adenocarcinoma and other intra-abdominal malignancies. We report the case of a 28-year-old female with AN associated with obesity, insulin resistance, and endometrial adenocarcinoma. Although rare, MAN is often an initial sign of malignancy and must trigger extensive investigation, particularly in patients with sudden development of possibly paraneoplastic dermatoses or in patients diagnosed with benign AN with any atypical features...

Thymus schimperi is a highly localized and a rare plant endemic to Ethiopia. An optimized and validated high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (HPLC-ESI-MS/MS) method was applied to characterize 23 polyphenolic compounds found in ethyl acetate extracts of the plant. From those, flavones dominated and luteolin was the major component contributing 21.83% of the total composition (or 46.05±0.59g/kg of fresh sample weight). Validation data showed a determination coefficient (R(2))≥0...

Malignant infiltration of pia and arachnoid mater, referred to as leptomeningeal carcinomatosis (LMC), is a rare complication of gastric carcinoma. The most common underlying malignancy in patients with LMC are leukemia, breast cancer, lymphoma, and lung cancer. We report a case of gastric adenocarcinoma that presented with LMC in the absence of overt gastrointestinal signs or symptoms. A 56-year-old Hispanic woman presented to the hospital with a three-week history of intermittent headaches and visual blurring...

BACKGROUND: Autoimmune gastritis (AIG) and adenocarcinoma-associated chronic atrophic gastritis (CAG) are both associated with oxyntic atrophy, but AIG patients demonstrate an increased risk of carcinoid tumors rather than the elevated risk of adenocarcinoma observed with CAG. We therefore sought to compare the characteristics of the metaplastic mucosa in AIG and CAG patients. METHODS: We examined markers for metaplasia (spasmolytic polypeptide expressing metaplasia (SPEM) and intestinal metaplasia) as well as proliferation (Ki67) and immune cell populations (neutrophils, macrophages, and eosinophils) in gastric sections from 16 female patients with autoimmune thyroiditis and AIG and 17 patients with CAG associated with gastric adenocarcinoma...
