|Abstract:||A workshop on the high risk group and the preventive oncology of prostatic cancer was held in Kyoto on July 28, 1976. The following subjects were presented: 1. Prostatic cancer epidemiology (Dr. Hirayama). 2. Influence of radiation for the occurrence of prostatic cancer (Dr. Kato). 3. Survival rate and endocrinological aspect of prostatic cancer (Prof. Kumamoto). 4. Experimental prostatic cancer (Prof. Yoshida). 5. Model mass screening for prostatic diseases using transrectal ultrasonotomography (Prof. Watanabe). 6. Cooperation study for prostatic cancer between Japan and U. S. A. (Prof. Yoshida). 7. A review on literatures of prostatic cancer epidemiology (Dr. Mishina). The review revealed evidences as follows: Two striking evidences in prostatic cancer epidemiology are prevalence only in older ages and different incidence between races. The highest frequency is observed among Negros living in U. S. and relatively higher among Whites commonly in U. S. and Europe. On the contrary, most Orientals show lower frequency, though that among Japanese is increasing remarkably during these one or two decades. Some migrant studies reveal that frequency among Japanese Americans is approximately in the middle between Japanese in Japan and American Whites. Although the occurrence of latent cancer is almost equal in each race, histological features of the cancer cells are more active in Whites or Japanese Americans than Japanese in Japan. Two probable evidences are influence from sexual life and heredity. This disease is fewer in unmarried men than married men and prevalent in men with greater sexual activities. A few kinds of hereditary disposition are reported. Two suspectable evidences are cadmium pollution and vegetables taking. High frequency might be observed among men chronically exposed to cadmium oxide dust over a period of ten or more years. Low frequency in vegetarians is also reported.|
