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 ration 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.
本文报告了一项关于肯尼亚食管癌的临床、放射学、组织学和地理学研究。研究发现，这种癌症在男性中的诊断率高于女性，男女比例为8:1（肯尼亚癌症登记处）。男性和女性最常见的发病年龄为50至59岁。食管最常受累的部位是中三分之一和下三分之一，比例几乎相等。值得注意的是，肿瘤在下三分之一处有未明原因的低分化倾向。此外，还对可能的病因进行了综述。
