A review of papers related to oral cancer reveals some non-uniformity in the classification of cancer of the lip. This paper examines the incidence of lip cancer in England and Wales using age-standardized and age- and sex-specific rates, and relates the results to those for other sites of oral cancer. There is a falling trend in age-adjusted incidence rates for lip cancer but not for intra-oral cancers, and the age-specific incidence shows a plateau effect for lip cancer after about 75 yr of age, whereas the incidence rate continues to rise throughout life for intra-oral cancers. These differences underline the importance of classifying cancer of the lip separately from other oral cancers.
对与口腔癌相关论文的回顾显示，唇癌的分类存在一些不一致性。本文使用年龄标准化率以及年龄和性别特异性率，研究了英格兰和威尔士唇癌的发病率，并将结果与口腔癌其他部位的发病率进行了关联。唇癌的年龄调整发病率呈下降趋势，而口腔内癌症则不然；年龄特异性发病率显示，唇癌在约75岁后呈现平台效应，而口腔内癌症的发病率在一生中持续上升。这些差异凸显了将唇癌与其他口腔癌分开分类的重要性。
