title: Epidemiological study of 314 cases of cancer of the bladder in the administrative department of Bas-Rhin, France.
abstract: This study is composed of two epidemiological investigations. The first concerns the geographical distribution of cancer of the bladder in the department of Bas-Rhin. The geographical distribution of 314 cases of cancer of the bladder in eight districts of the Bas-Rhin has been studied. The resultant map shows considerable variations in morbidity. The urban predominance may be due to environmental factors. The second enquiry concerns the frequency of multiple cancers of different primary sites occurring in cases of cancer of the bladder. Nine such cases have been identified. There may be a common predisposing factor in such cases. All patients were heavy smokers.
