前立腺癌の臨床統計病理学的研究 1.秋田県における羅患率の算定

Abstract

An attempt was made to clarify the regional difference of the morbidity of prostate cancer in Akita prefecture. Clinical records of 166 patients with prostate cancer first diagnosed by histological examination during the 5 year's period from 1976 to 1980 were obtained from 20 hospitals in Akita Prefecture. The average annual morbidity of prostate cancer was 5.52 per 100, 000 in male. The greatest number of patients was found in the age group 70-79 years old (84), followed by those 60-69 years old (49) and then those 80-89 years old (24). Limited to the over 60 average annual morbidity of prostate cancer was 39.6. As for regional difference of morbidity, there was no significant difference between the urban and rural areas. Among the 9 districts of Akita Prefecture, a morbidity remarkably higher than the average was found in Noshiro-Yamamoto (9.2) and Yuzawa-Okachi (11.4) distiricts.
