title: [A result of mass-screening for uterine cervical cancer in Hyogo prefecture (author's transl)].
abstract: A result of mass-screening for uterine cervical cancer conducted by Hyogo Cancer Hospital performed using mobilunit from 1965 to 1978 was analyzed and presented in this paper. The total number of women taking our initial screening examination was 188, 183.5% women screened or 9,447 were transferred for the further accurate examination. The rate of participants for this 2nd examination was 93.8% on the average. In this initial screening examination, a result of cytological examination on Papanicolaou's classification was as follows; 94.87% for class I and II, 4.81% for class III, and 0.21% for class IV and V. In the 2nd examination, the rate of the negative, suspected positive were 70.6%, 22.5% and 6.9% respectively. 759 cervical cancers were detected in our screening. The detecting rate of cervical cancer was 0.4% among initially screened women and 8.6% among women who appeared for the accurate examination. As the detecting rate among women for the 2nd examination became higher year by year (20% increase during recent 3 years), the accuracy of our screening methodology appeared to be improving. The incidence rate of cervical cancer in our screening was classified as stage 0; 49.0%, Ia; 36.4%, Ib; 9.1%, II; 3.9% an III; 1.6%. The most of detected cancer was occupied by cancer in situ and early invasive cancer. Annual review showed there is a gradual and steady increase in incidence rate to stage 0 in our screening.
