The Canadian Task Force On Preventive Health Care Releases Updated Guideline For Cervical Cancer Screening
Task Force says annual screening for asymptomatic women is unnecessary
OTTAWA, Jan. 7, 2013 /CNW/ - The Canadian Task Force on Preventive Health Care (Task Force) today released an updated guideline on cervical cancer screening, recommending women aged 25-69 be screened at an interval of three years. The Task Force, an independent body of fourteen specialists with expertise in prevention, and primary care in Canada, says early and frequent (often annual) cervical screening is unnecessary. The Guideline is published in the Canadian Medical Association Journal - http://www.cmaj.ca/lookup/doi/10.1503/cmaj.121505.
The guideline is an update to that last published by the Task Force in 1994 and is based on the best and latest evidence in cervical cancer screening. Aimed at physicians, policy makers and Canadian women, the updated Guideline identifies the optimal use and frequency of screening (Pap tests) for cervical cancer in asymptomatic women who are or who have been sexually active, regardless of sexual orientation.
"Since the introduction of Pap tests in Canada, the proportion of women getting cervical cancer has declined from 1.5% of all women to 0.66%, and the proportion dying from cervical cancer had declined from 0.94% to 0.22%" said Dr. James Dickinson, member of the Task Force and chair of the guideline working group. "And while it is likely that most of this improvement is a result of screening, other countries have achieved similar outcomes despite initiating screening at an older age and implementing longer screening intervals. Reducing the number of pap tests gives women the benefit from screening, while reducing the inconvenience, discomfort and potential harms caused by early and excessive testing."The current guideline differs from the previous 1994 CTFPHC recommendations in a number of ways:
- The updated Guideline says routine screening is not recommended in sexually active women who are younger than 25. The 1994 Guideline recommended annual screening with Pap tests after initiation of sexual activity or at age 18.
- The updated Guideline recommends asymptomatic women aged 25-69 (who are or have been sexually active) be screened at an interval of 3 years. The 1994 Guideline recommended women aged 20-69 be screened every three years - but only after 2 normal Pap tests.
- In the updated Guideline, screening is now explicitly recommended in women older than 69, if prior screening has not been adequately performed. In the previous Guideline, screening women aged 70+ was not recommended.
