Despite the decreasing incidence and mortality from gastric cancer, it remains a major health problem worldwide. Ninety percent of cases are adenocarcinomas. Here, we report a case of gastric adenocarcinoma developed after successful treatment of prior primary gastric diffuse large B-cell lymphoma (DLBCL). Our patient was an elderly man with primary gastric DLBCL in whom complete remission was ...

Lack of apoptosis is a key factor in carcinogenesis and tumor progression. Survivin is a member of the inhibitor of apoptosis protein (IAP) family. Second mitochondria-derived activator of caspases/direct inhibitor of apoptosis-binding protein with low pI (Smac/DIABLO) is an antagonist of IAPs. Recently, Smac/DIABLO was identified as a potent therapeutic target. However, the clinical significan...

AIM to investigate the expression of proliferating cell nuclear antigen (PCNA) and E-cadherin in gastric carcinoma and to analyze their clinical significance. METHODS A total of 146 patients were selected for this study, including 38 patients with intestinal metaplasia, 42 with dysplasia, and 66 with primary gastric cancer. In addition, 40 patients with normal gastric tissues were selected as...

BACKGROUND/AIMS Gastric cancer (GC) is the second leading cause of cancer-related deaths worldwide and is the most frequent cancer in Iran. Epstein-Barr virus (EBV) has been shown to be associated with gastric cancer. The present study was carried out to investigate the prevalence of Epstein-Barr virus (EBV) associated gastric cancer among Iranian patients. METHODS Ninety formalin fixed paraf...

objective(s):mirnas have been proposed to be key regulators of tumorigenesis, progression and metastasis. however, their effect and prognostic value in gastric cancer is still poorly known. materials and methods: gastric cancer cell lines were cultured. tissue samples obtained from 36 gastric cancer patients were used for quantitative real-time pcr (qrt-pcr) analysis. the tissue microarrays (tm...

BACKGROUND To assess the extent of gastric intestinal metaplasia (IM) in gastrectomy specimens in populations of the Pacific basin having different incidence of gastric carcinoma. MATERIALS AND METHODS One thousand three hundred and nine-two gastrectomies were investigated: 1088 had a gastric carcinoma and 304 miscellaneous gastric diseases. Twenty-one thousand three hundred and fourteen hist...

We report the establishment and characterization of four continuous cell lines derived from human primary and metastatic gastric carcinomas, and we compare their properties with a panel of colorectal carcinoma cell lines previously established and reported by us. Our success rate in culturing gastric carcinomas was relatively low, especially from primary tumors, compared to colorectal carcinoma...

background little is known about the possible influence of demographic and histological risk factors on the survival of patients with esophageal and gastric cancer. objectives based on the available registry and follow-up information, this study compares 1-5 year survival rate of gastric and esophageal cancer. patients and methods through a concurrent (prospective) cohort study, all 366 patient...

Metastasis of breast carcinoma to the stomach is relatively uncommon, although metastasis to other organs such as lung, bone, and lymph nodes is not rare. It may cause difficulty in differentiating from primary gastric carcinoma. We report a case of signet ring cell carcinoma of the breast with metastasis to the stomach with illustrations of histologic findings of both lesions. The results of i...
