Mass screening for cervical cancer in Norway: evaluation of the pilot project.
The Norwegian Department of Health and Social Affairs initiated a national screening program for cervical cancer in 1990, with all women aged 25 to 70 years to be offered cervical screening every three years. During the first three years of the program (November 1991-October 1994), all spontaneous cervical cytology in Norway was recorded at the Norwegian Cancer Registry. In addition, women in the counties of Vestfold and Sør-Trøndelag were invited individually to be screened. The aim of the present study was principally to evaluate the organization aspects of a nationwide, population-based screening program for cervical cancer in Norway. Special attention was paid to the coverage, the attendance rate, and the cytologic findings in the two-county study area. A total of 1,581,379 Pap smears were recorded from November 1991 to October 1994. Most smears were taken from women under age 30 years (31.7 percent). About 25 percent of the women aged 25 to 29 years had more than one normal smear. In the study area, a coverage of about 71 percent in the age group 25 to 69 years was achieved. The pilot project also has shown that it is possible to recruit elderly women into screening. However, no difference was noted between the study and the reference area with regard to findings per smear of precursor lesions (CIN 3, modified SNOMED coding system). The experiences from three years of recording and the implementation of the pilot project have provided useful guidelines for the national screening which began in January 1995.
