Cervical cancer screening programs: summary of the 1982. Canadian task force report

Abstract

The Canadian Task Force on Cervical Cancer Screening Programs, which produced its first report in 1976, was reconvened by the Department of National Health and Welfare in 1980 in response to concerns expressed about the significance of new data, changing sociosexual patterns and wide variations in the implementation of the 1976 recommendations. This article is a summary of the 1982 task force report. In addition to updates of the 1976 material new sections appear on groups at risk, mathematical models of screening, quality control in screening programs, cytologic screening coverage of the Canadian population and management of patients with abnormal smears. The 1982 recommendations deal with frequency of screening, laboratory quality control and follow-up mechanisms. The task force concludes that measures to improve the quality and sensitivity of screening programs and to include women who have never been screened will be more effective in reducing mortality from carcinoma of the cervix than will attempts to increase the frequency of screening. The task force views as unnecessary the annual screening of women over 35 years of age whose previous smears have been normal. Since younger women are sexually more active and tend to have more than one sexual partner they are at high risk. Therefore, the task force recommends annual screening for sexually active women aged 18 to 35 years. Physicians, health care professionals and government health agencies have a role to play in informing women about the recommended intervals for cervical smears and ensuring that screening programs of adequate quality are available. Although women are primarily responsible for entering and continuing in such a program, government-sponsored registries are essential if the full potential of cervical smear programs is to be realized.
