Background: Scant data on upper gastrointestinal cancers in Rwanda exist to guide potential prevention efforts. We evaluated the epidemiological, clinical and histopathological data among patients with gastric and esophageal tumors at a tertiary Referral Hospital in Rwanda. Methodology: We performed a retrospective review of histologically-confirmed esophageal and gastric cancers in adults age ≥ 18 yrs. old presenting to a university teaching hospital (Centre Hospitalier Universitaire de Butare) from 2014-2019. Variables included age at diagnosis, sex, clinical presentation, tumor location and histopathological type. Results: There were 149 upper gastrointestinal cancers, of which 137 (92%) were gastric and 12 (8%) were esophageal. Gastric cancer patients had a mean age at presentation of 56.9 ± 12.3 years (range 21 - 87). Presenting symptoms were epigastric pain (78.8%), weight loss (53.3%), post-prandial vomiting (52.6%), early satiety (29.9%), epigastric mass (24.8%), hematemesis (19.7%) and melena (16.8%). The location was antrum 50.3%, corpus 21.8%, fundus 8%, and cardia 8%. Tumor type was adenocarcinoma in 94.1%. Helicobacter pylori infection was present in 108 (78.8%). Esophageal cancer patients had a mean age of 54.4 ± 9.5 years (range 35 - 72). Presenting symptoms were dysphagia (100%) and weight loss (83%). The most common site was lower third esophagus (9/12), and adenocarcinoma cancer subtype accounted for 5/12 (41.6%) cases. Conclusion: Gastric adenocarcinoma was the most commonly diagnosed upper gastrointestinal cancers and was associated with a high prevalence of H. pylori infection. This study lays the foundation for future work to improve cancer outcomes in Rwanda.
