Cancer of the oesophagus was a rare disease in the South African black population until the last few decades. Increases in incidence have occurred and at present it is the commonest cancer in black men in many parts of South Africa. A case-control study of 200 oesophageal cancer patients and 391 hospital controls has been carried out in order to determine the risk factors in the urban black population of Soweto. The results indicate that the cancer patients were long-term urban residents from a very low socio-economic group. The association between smoking pipe tobacco and oesophageal cancer previously noted in South Africa is confirmed. In addition, consumption of traditional beer was found to be a major risk factor.
直到过去几十年，食管癌在南非黑人人口中还是一种罕见疾病。发病率出现了上升，目前在南非许多地区，它是黑人男性中最常见的癌症。为了确定索韦托城市黑人人口中的风险因素，对200名食管癌患者和391名医院对照者进行了一项病例对照研究。结果表明，癌症患者是来自非常低社会经济群体的长期城市居民。此前在南非发现的吸食烟斗烟草与食管癌之间的关联得到了证实。此外，发现饮用传统啤酒是一个主要风险因素。
