Correlation between endoscopic suspicion of gastric cancer and histology in Nigerian patients with dyspepsia.
Article in English | IMSEAR | ID: sea-124881
ABSTRACT
Gastric mucosal biopsies of 77 dyspeptic patients whose endoscopic features were suggestive of cancer and 56 patients with uncomplicated duodenal ulcer (DU) were subjected to histopathological analysis. Gastric cancer was confirmed in 18 (23.4%) of the 77 patients but not in 59 (76.6%). 4 (5.2%) of the 18 patients had early gastric cancer (EGC). Histopathological findings in the stomach biopsy of the 59 patients in whom cancer could not be confirmed were compared with those of the 56 patients with DU. Intestinal metaplasia (IM) was present in 32.2% of the 59 cases with endoscopic suspicion of gastric cancer and in 16.1% of the 56 DU controls (P < 0.05). Mucosa-associated lymphoid tissue (MALT) occurred in 28.8% of the cancer-resembling cases and in 12.5% of the DU patients (P < 0.05). The difference in the prevalence of gastric mucosal atrophy and Helicobacter pylori infection between the two groups (83% vs. 71.4%) did not reach statistical significance (P > 0.10). All 18 patients with gastric cancer were positive for Helicobacter pylori and the prevalence of the infection approached 95% in those with IM and MALT. This study shows that IM and MALT present with endoscopic appearances that resemble that of gastric cancer and that along with the latter, their main aetiological agent is Helicobacter pylori.
