Clinical statistics of general patients and A-bomb exposed patients in the Red Cross Nagasaki A-Bomb Hospital was carried out during the 10 year period from 1964 to 1973 to study the number of outpatients and inpatients by year, sex ratio and the incidence of malignant tumors.
Concerning bladder tumor, prostatic cancer and testis tumor that were highly frequent among malignant tumors in A-bomb exposed patients, the incidence in the general group and the A-bomb exposed group was analyzed by the number of outpatients, the number of inpatients and sex ratio, and was also compared with the frequency in the clinical statistics in Japan.
The incidence of bladder tumor showed no difference between general patients and A-bomb exposed patients. The incidence of prostatic cancer in A-bomb exposed patients was approximately three times as high as that in general patients but it was much lower than the statistical value in Japan. The incidence of testis tumor in A-bomb exposed patients was twice as high as that in general patients as far as male outpatients were concerned, and was nearly equal as far as male inpatients were concerned. However, it was noteworthy that the incidence ranked high in the national statistics of testis tumor in Japan.
