Abstract

We examined the effect of potential interfering factors that play major roles in the outcome of our patients with stomach cancer. 100 consecutive patients diagnosed with gastric cancers were prospectively observed, treated and followed from November 2009 to January. Absence of Helicobacter pylori infection (P=0.027), absence of vascularisation (P<0.001), and undetermined histopathological type of adenocarcinoma (P=0.003) were factors significantly associated with higher grade of gastric lesions. Life tables were used to define survival of gastric cancers. Survival rates of these patients at 1st week, 1st month, 2nd month, 3rd month, and 6th month were 97, 96, 91, 90, and 82, respectively. The only determinant of 6 months of survival was age over 68 (P=0.039). Our study confirms our previous knowledge that gastric cancers have unfavorable outcome in Iran.
