Abstract
PURPOSE: The aim of this paper is to study urinary5-hydroxyindoleacetic acid (5-HIAA) in gastric cancer patients with a biochemical method and compare this metabolite with normal control and individuals with chronic gastritis. MATERIALS AND METHODS: The subjects were 48 histologically proven gastric adenocarcinoma patients. They were 10 women and 38 men with mean age of 63.73 years. For determination of urinary excretion of 5-HIAA, a biochemical method was applied. According to kit protocol, the patients' fresh urine was added to the reagent material, and the color of the sediment that was the result of interaction between 5-HIAA and the mercury salt was compared with the standard colorimetric plate of the kit. The same method was also performed for a group of 47 patients with chronic gastritis and also a group of 50 normal individuals (age and sex matched). RESULTS: Urinary 5-HIAA was significantly higher in gastric cancer patients compared to individuals with chronic gastritis and normal controls (P value <0.001), but no association was detected in urinary 5-HIAA based on age, sex, or site of tumor and tumor grade in gastric cancer patients group. Also, no significant difference was noted in 5-HIAA excretion between chronic gastritis and normal control groups. CONCLUSION: Urinary excretion of 5-HIAA is significantly higher in the gastric cancer patients in comparison with that of chronic gastritis patients or normal individuals. So, this test could be regarded as a tumor marker in conjunction with other modalities in diagnosis of gastric cancer.
