This study was designed to provide up-dated incidence figures for bladder cancer in France.
The method used was based on modelling of the mortality/incidence ratio observed in French departments with cancer registries.
The number of invasive cancers, which represent an average of slightly less than two-thirds of all bladder tumours diagnosed in France, increased in males from 5,591 in 1990 to 7,203 in 1990 and 8,986 in 2000. For females, these figures were 1,593, 1,744 and 1,787, respectively. This increase was mainly due to growth of the population, as incidence rates varied only slightly (+1.14% per year in males and -0.5% in females). Over the same period, the risk of death from bladder cancer decreased for both sexes.
The diversity of the classifications, which clearly reflects the difficulty of defining bladder tumours, raises problems for descriptive epidemiology. This situation will probably be clarified by the consensus reached by pathologists over recent years.
本研究旨在提供法国膀胱癌的最新发病率数据。
所采用的方法基于对法国设有癌症登记处的各部门所观察到的死亡率/发病率比值进行建模。
浸润性癌的数量在男性中从1990年的5591例增加到1995年的7203例以及2000年的8986例，浸润性癌平均占法国诊断出的所有膀胱肿瘤的略少于三分之二。对于女性，这些数字分别为1593例、1744例和1787例。这种增加主要是由于人口增长，因为发病率仅略有变化（男性每年增长1.14%，女性每年下降0.5%）。在同一时期，男女因膀胱癌死亡的风险均有所下降。
分类的多样性清楚地反映了定义膀胱肿瘤的困难，给描述性流行病学带来了问题。近年来病理学家达成的共识可能会澄清这种情况。
