[Problems in urinary bladder cancer in the aged].
In general, the result of treatment for bladder cancer in elderly patients over 70 years seems less favorable than younger patients. The analysis of case records of our clinic suggests two responsible factors. First, proportion of invasive to superficial cancer is higher in elderly than younger patient; the proportions are 37, 35, 29, 23 and 18%, in ninth, eighth, seventh, sixth and under-sixth decade respectively. Second, the cause of death indifferent to primary cancer is more frequent in elderly than younger patient. Main intercurrent diseases are hepatic, cerebro-vascular, cardio-pulmonary diseases, and cancer of other organs. It is concluded that, superficial cancer should be distinguished more accurately from invasive cancer and treated more properly especially in elderly patient.
