Page 22 - Screening for Cervical Cancer: Systematic Evidence Review
P. 22
Chapter I. Introduction
importance of assessing potential harms of screening becomes clear. The psychological effects
of labeling young women with an anxiety-provoking, possibly precancerous condition, and the
associated individual, health care system, and societal costs deserve attention. Ideally, screening
tools would help guide selection of the intensity of intervention across the spectrum of cervical
dysplasia.
For this report, we sought evidence about screening in older age groups and after
hysterectomy. We also looked at methods to determine the optimal interval and at the potential
contribution of new technologies and HPV testing methods to clinical prevention of cervical
cancer. Furthermore, we sought evidence about the cost implications, the population to be
screened, and potential harms that follow from screening.
Prior Recommendations
US Preventive Services Task Force
The second edition of the Guide to Clinical Preventive Services from the US Preventive
Services Task Force gave an A to the recommendation of a regular Pap test for all women who

are or have been sexually active and who have a cervix.

The Task Force further stipulated (pg 112):
There is little evidence that annual screening achieves better outcomes than screening
every 3 years (B recommendation). The interval for each patient should be
recommended by the physician based on risk factors. There is insufficient evidence to
recommend for or against an upper age limit for Pap testing, but recommendations can be
made on other grounds to discontinue regular testing after age 65 in women who have
had regular previous screening in which the testing has been consistently normal (C
recommendation). Women who have undergone a hysterectomy in which the cervix was
removed do not require Pap testing unless the hysterectomy was performed because of
cervical cancer or its precursors.
