    Journal: Afr Health Sci; 2014 Mar; 14(1):17-21. PubMed ID: 26060453.
    Abstract:
    BACKGROUND: Esophageal cancer is the eighth most common cause of cancer death worldwide with squamous cell carcinoma and adenocarcinoma carcinoma as the main histopathological subtypes. Esophageal cancer is known for its marked variation by geographic region, ethnicity, and gender. Hitherto, the histopathological subtype of this cancer in Northern Uganda were not known. Therefore the aim of the study was to describe the characteristics of esophageal cancer with respect to the histopathologic subtypes, different sites of occurrence, age and gender in this region since its distribution varies with location. METHODS: The study was carried out at Lacor Hospital, in northern part of Uganda. The record of 71 patients who had endoscopic and histopathological diagnosis of cancer of esophagus over a period of 3 years between January 2009 and December 2011 were retrospectively analyzed. RESULTS: A total of 140 patients had endoscopic diagnosis of cancer of the esophagus and of these, 71 patients had both endoscopic and histopathological diagnosis of cancer of esophagus during the three-year period covered in the study between January 2009 to December 2011. The female to male ratio was 1:3 with mean age of 55.5 years ± SD 11.8. The common histopathological pattern of cancer of esophagus was squamous cell carcinoma of esophageal consisting of 66 patients (93.o%). The ratio of squamous cell carcinoma to adenocarcinoma was 13:1.The majority of the esophageal cancers were found in the middle third with 38 patients (53.52%), followed by lower third with 27 patients (38.0%) and the upper third which was only 6 patients (8.5%). CONCLUSSIONS: Squamous cell carcinoma is the most common histopathological subtype in this geographical location with overall cancer of the esophagus mainly affecting the lower 2/3 of the esophagus with the majority in the middle third.
