A twenty-year period in mass screening for uterine cervical cancer in Fukushima Prefecture.

Abstract

To explore the change in age distribution of patients with uterine cervical cancer and its precursors, we analyzed 2,168,923 women in a series of mass screening for uterine cervical cancer in Fukushima Prefecture. The first examination rate was not increased over a 20-year period. During the screening period, severe dysplasia was found in 693 women, carcinoma in situ in 672 women, microinvasive carcinoma in 517 women, and frank invasive carcinoma in 421 women. The numbers of patients with frank invasive carcinoma was decreased gradually in every age group, which might reflect the effectiveness of our mass screening project. Although the detection rates of severe dysplasia, carcinoma in situ and microinvasive carcinoma have not changed in patients groups over 40 years old, the detection rates were increased in patients under the age of 39. These results may reflect a recent tendency for cervical cancer to increase in young women. It is important, therefore, to increase the screening rate for young women to prevent the progression with advanced cervical cancer.
