BACKGROUND Gastric cancer is a common malignancy worldwide and a common cause of death from cancer. Despite recent advances in multimodality treatment and targeted therapy, complete resection remains the only treatment that can lead to cure. This study was devised to investigate the technical feasibility, safety and oncologic efficacy of laparoscopy-assisted gastrectomy for advanced gastric can...
Levels of gastric juice nitrite, several urinary N-nitroso compounds, and other analytes were examined among nearly 600 residents in an area of Shandong, China, where precancerous gastric lesions are common and rates of stomach cancer are among the world's highest. Gastric juice nitrite levels were considerably higher among those with gastric juice pH values above 2.4 versus below 2.4. Nitrite ...
Aim. Amino acid metabolism in cancer patients differs from that in healthy people. In the study, we performed urine-free amino acid profile of gastric cancer at different stages and health subjects to explore potential biomarkers for diagnosing or screening gastric cancer. Methods. Forty three urine samples were collected from inpatients and healthy adults who were divided into 4 groups. Health...
Prognostic value of DNA-ploidy in gastric cancers is still a matter of controversy. A possible explanation for the discrepant results reported in the literature could be sampling error in tumours with multiple stemlines differing in DNA-ploidy [2,4]. In order to determine whether or not such hetero-geneity exists and play a role in biology of gastric cancers we have analysed two different types...
background: this study testing the effectiveness ,toxicity and tolereability of new chemotherapeutic regimen (consist of irinotecan 5-fu and leucovorin) in locally advanced and metastatic gastric cancer. patients and methods: patients with locally advanced gstric cancer (atleast stage 3)or metastatic gastric cancer that no treated previously with chemotherapeutic agents entered onto this study....
The tumor suppressor p16 is a negative regulator of the cell cycle, commonly believed to act in the nucleus. We recently found that p16 protein is expressed in the cytoplasm of gastric cancer cells, concomitantly with anion exchanger 1 (AE1). The aim of this study was to analyze the significance of cytoplasmic p16 and its relationship to AE1 in the progression of gastric cancer. Expression of p...
Background and purpose: Mortality rate from gastric cancer is growing in the world. Nowadays, in many cancers, between cancer development and changes in EGF receptor expression levels there is a very precise relationship. Perhaps one of the best known of these changes in gastric cancer is over expression of Her1 & 2 receptors. This study investigated the expression rate of these two receptors i...
Gastric adenocarcinoma is the second leading cause of death due to cancer in the world and in advanced stages the prognosis is poor with current therapies. Over-expression of HER-2/neu has been seen in several cancers such as gastric cancer and its expression is associated with poor prognosis. The aim of this study is to evaluate the over-expression of HER-2/neu in gastric biopsy samples of pat...
