Bladder cancer in the three main age groups

ABSTRACT

Despite of the fact that the incidence of carcinoma of the urinary bladder associated with bilharziasis that occurs at young age compared to non-bilharzial type, the incidence of this tumor in young adults was not high. On the other hand, over 70- years the incidence was three times greater than below the age of 40 years. A retrospective survey of bladder cancer cases during six years from September 1987 to September 1993 showed 18.2% incidence. The two groups of extreme age were analyzed [below 40 years and 70 years and above] and compared with middle age group. Out of the twenty four cases aged below 40 years [4.8%], only 4 patients [0.8%] was classified histologically as transitional cell carcinoma [T.C.C.]. Out of the 90 patients, presented over 70 years of age [18.1%], 45 showed TCC [9%] on histopathological examination, compared to 35.7% in the middle age group
