National age-adjusted rates of mortality from esophageal cancer have increased among Blacks in the United States, while remaining nearly unchanged among Whites. By 1980, esophageal cancer had become one of the leading causes of cancer death among Blacks, with the excess among males under age 55 exceeding six-fold. Inferences about the causes of esophageal cancer cannot be made from this descriptive survey, but the rising trend raises etiologic hypotheses about environmental exposures (e.g., alcohol, tobacco, nutrition) that may differentially affect Blacks.
在美国,黑人经年龄调整后的全国食管癌死亡率有所上升,而白人的死亡率几乎保持不变。到1980年,食管癌已成为黑人中癌症死亡的主要原因之一,55岁以下男性的超额死亡率超过了六倍。这项描述性调查无法推断出食管癌的病因,但这种上升趋势引发了关于环境暴露(如酒精、烟草、营养)的病因假设,这些环境暴露可能对黑人产生不同的影响。
