Cancer of the middle ear is an uncommon tumor which has a very poor prognosis. A population-based analysis shows that there are two marked differences between men and women for middle ear cancer in England and Wales: (1) the incidence rate in men continues to rise with advancing age, but in women the rise is proportionately much less after 75 years of age; and (2) the mortality rate in men decreases after 70 to 75 years of age, whereas the mortality for women continues to rise with advancing age. The significance of these differences is not yet clear. No other epidemiologic reports related to middle ear cancer has been found in the literature.
中耳癌是一种罕见的肿瘤，预后很差。一项基于人群的分析表明，在英格兰和威尔士，中耳癌在男性和女性之间存在两个显著差异：（1）男性的发病率随着年龄增长持续上升，但女性在75岁以后上升幅度相对较小；（2）男性在70至75岁以后死亡率下降，而女性的死亡率则随着年龄增长持续上升。这些差异的意义尚不清楚。文献中未发现其他与中耳癌相关的流行病学报告。
