Retrospective Study of Carcinoma of the Esophagus in Kenya

Departments of Pathology [D. G. G., D. A. O. O.] and Surgery [P. A. O., A. W.], University of Nairobi, and Department of Radiology, Kenyatta National Hospital, Nairobi [F. J. M.]

A clinical, radiological, histological, and geographical study of carcinoma of the esophagus in Kenya is reported. It was found that this cancer is diagnosed more often in males than in females, with a ratio of 8:1 (Kenya Cancer Registry). The most common age in males and females is 50 to 59 years. The regions of the esophagus most commonly involved are the middle and lower thirds, in almost equal proportions. An unexplained tendency for the tumor to be poorly differentiated towards the lower third is noted. In addition a review on the possible etiological factors is presented.
