RATIONALE: Women who do not undergo routine cervical screening may be more likely to collect a self-sample for human papillomavirus testing.

PURPOSE: This randomized clinical trial is studying self-sampling in women who do not undergo routine cervical screening.

Condition Intervention
Health Status Unknown Precancerous Condition Behavioral: compliance monitoring Other: cervical Papanicolaou test Other: educational intervention Other: screening questionnaire administration Other: survey administration Procedure: colposcopy

Study Type: Observational
Official Title: The Potential Role of Self-sampling in Women Who do Not Attend for Cervical Screening - a Randomised Controlled Trial

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Comparison of the percentages of women responding to the invitation to return a self-sampling kit vs responding to an invitation for a cervical smear

Secondary Outcome Measures:
  • Response to the invitation for further investigation following a positive test result (colposcopy for women with a smear showing mild dyskaryosis or above, smear +/- colposcopy for those with a positive HPV test)
  • Response to the request to return a survey regarding demographic information and reasons for previous non-attendance for screening

Estimated Enrollment: 3000
Study Start Date: June 2009
Study Completion Date: March 2011
Primary Completion Date: February 2010 (Final data collection date for primary outcome measure)
Detailed Description:


  • To ascertain whether women who do not attend for cervical screening are more likely to respond to the opportunity to collect a self-sample for human papillomavirus (HPV) testing, or to respond to a further invitation to undergo a cervical smear.
  • To ascertain whether such women will attend for further investigation if they have a positive screening test (HPV test or cervical smear).

OUTLINE: Patients are randomized to 1 of 2 arms.

  • Control: Patients receive an invitation for a routine cervical smear and a cervical screening survey. Information regarding attendance for smear or colposcopy is collected at the Primary Care Trust.
  • Study (self-sampling kit): Patients receive an explanatory letter, an information sheet about the study, a consent form, information about human papillomavirus (HPV) and HPV testing, a self-sampling test kit, and an invitation to take their own HPV sample and return it to the research group for processing. Patients also receive a cervical screening survey. Patients who attend for further investigation following a positive HPV result go to St. Mary's Hospital Colposcopy Unit, Paddington. During this visit cervical smear tests are performed and women are offered immediate colposcopy so that they would not need to return for colposcopic examination if their smear test is abnormal.
