There is a general interpretation that the distribution and pattern of various cancers exhibit geographical variations between developed and developing countries. However, as far as oral cancer is concerned, these differential patterns of distribution are not much documented.
This review is aimed to bring in the existence of geographical disparities and its pattern for oral cancer incidence and mortality. The objectives of this review are: (1) To compare and comment on the trends in estimates for oral cancer incidence and mortality for the years 2002, 2008, and 2012. (2) To correlate oral cancer incidence and mortality values for 2012 with the human development index (HDI) scores for 2012 for each country. Design: Ecological approach and entire review was carried out using two secondary data sets, and they were (i) Age-standardized oral cancer incidence and mortality value for all countries published by the International Agency on Cancer Research for the years 2002, 2008, and 2012. (ii) HDI score for all countries for the year 2012 released by the United Nations Development Program.
A diametric pattern of distribution was observed across the two strata of countries. When developed countries have higher rates for incidence, low developed countries have higher rates for mortality.
有一种普遍的解释认为，各类癌症的分布和模式在发达国家和发展中国家之间呈现出地域差异。然而，就口腔癌而言，这些不同的分布模式鲜有文献记载。
本综述旨在揭示口腔癌发病率和死亡率的地域差异及其模式。本综述的目标如下：（1）比较并评论2002年、2008年和2012年口腔癌发病率和死亡率估计值的趋势。（2）将2012年各国的口腔癌发病率和死亡率值与2012年的人类发展指数（HDI）得分进行关联。设计：采用生态学方法，整个综述使用了两个二手数据集，分别是：（i）国际癌症研究机构公布的2002年、2008年和2012年所有国家的年龄标准化口腔癌发病率和死亡率值。（ii）联合国开发计划署发布的2012年所有国家的HDI得分。
在两类国家中观察到了截然相反的分布模式。当发达国家发病率较高时，欠发达国家的死亡率较高。
