Background And Objective:
gastric cancer is the fifth most prevalent cancer and the fourth cause of death because of cancer. In Iran, northern and northwestern regions are considered gastric cancer hot spots. Identifying serum biomarkers could be helpful in early diagnosis of patients with gastric adenocarcinoma (GAC). Increase in progastrin level has been reported in different cancers. Given the diagnostic value of this biomarker, this study aimed to determine the diagnostic role of progastrin serum biomarker in patients with gastric cancer.
Methodology:
In this case-control study, forty patients with gastric cancer who were diagnosed by endoscopy and pathologic findings and visited Mazandaran Comprehensive Cancer Center. The participants had received no treatment yet and entered this study. The participants in case group were compared with the control group including forty-two individuals with no history of gastrointestinal cancer in their first-degree relatives and visiting the lab for routine tests. Progastrin serum level was assessed using ELISA kit. The Kruskal-Wallis test and Mann Whitney test, both non-parametric) were used for statistical analysis and the relation between the variables was examined using Pearson's correlation coefficient at 95% confidence level in SPSS 16.
Findings:
In this study, progastrin serum level was significantly higher in patients with gastric cancer compared with normal participants (P = 0.035). Progastrin serum level had no significant relation with tumor clinicopathologic parameters (p-value > 0.05).
Conclusion:
Increase in progastrin may be utilized as a predictive factor for gastric cancer.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
