General practitioners’ perception of risk factors for cervical cancer development: Consequences for patient education
Introduction
Accumulated evidence for the pivotal role that human papillomavirus (HPV) plays in the development of cervical cancer, has fuelled the search for applications of HPV in vaccine development and primary and secondary cervical screening. Already, HPV detection is used in triage of borderline or mildly dyskaryotic smear results [1], [2]. Last year, the United States Food and Drug Administration has approved Digene's Hybrid Capture 2 assay for use with a Pap test to adjunctively screen women aged 30 years and older for the presence of high-risk HPV infection. This was based on the theory that after the age of 30, the negative predictive value of both Pap and HC2 assays would improve the sensitivity of cervical cancer screening. This introduction of HPV detection in cervical screening will make it necessary to provide appropriate information to the general public. Several studies have been performed to investigate the knowledge of HPV, but mostly in college students [3], [4], [5], [6]. From these studies, it can be concluded that knowledge of HPV is very limited. In a previous study, we have developed a questionnaire concerning risk factors for cervical cancer development which was completed by 162 women [7]. From this study, it appeared that the women were not well informed of the most important risk factors, and almost unaware of the role of HPV as a sexually transmitted agent. Only 3% of the women could name HPV as the viral agent involved in cervical cancer development. Furthermore, it would appear that the majority of the women did not obtain the information needed to fill in the questionnaire from their general practitioner or gynaecologist. The aim of this study was to investigate whether general practitioners have appropriate knowledge of the relationship between HPV and cervical cancer to be able to inform women presenting for cervical screening.

Methods
A three-page self-administered questionnaire was developed to measure perception of risk factors for cervical cancer development. The questionnaire contained 20 possible risk factors. Respondents were asked to rate their view of the impact of a given risk factor on the development of cervical cancer on a scale of 1 (unimportant) to 5 (very important). In the case of two risk factors (bacterial and viral infection), there was room for naming the agent involved, if known. The final question asked
Results
Sixty GPs filled in the questionnaire (33 men, 24 women, 3 did not specify gender). Twenty-eight trainees also filled in the questionnaire (10 men, 18 women). The 20 risk factors suggested in the questionnaire were: smoking, alcohol, drugs, young age at start of sexual activity, number of sex partners, sexual behaviour of the male partner, bacterial infection, viral infection, large number of children/pregnancies, immune suppression (e.g. due to transplantation), hormonal therapy (e.g. due to
Discussion
Currently, in Flanders, Belgium, HPV DNA testing is only being used for triage of ASCUS smears. However, in the light of the approval by the FDA of the Hybrid Capture 2 test for simultaneous Pap smear and HPV testing, it can not be ruled out that HPV testing will become a routine test in women of 30 years and older. In both situations, accurate information about HPV will be crucial to inform women's screening choices and to avoid psychosocial problems in women with positive HPV DNA test

Cervical cancer screening: Women's knowledge, attitudes, and practices in the region of Monastir (Tunisia)
2012, Revue d'Epidemiologie et de Sante PubliqueCitation Excerpt :In our study, only 12% of women reported that healthcare providers gave them information on cervical screening. This low rate can be improved by focusing on the education of medical students and practitioners, so that they can supply patients with sufficient background information to make an informed choice on participating in cervical cancer screening [22,23]. Some studies report that the most significant predictors of CCS were marriage and advanced age [24].
Everything you always wanted to know about HPV (but could not ask your doctor)
2010, Patient Education and CounselingCitation Excerpt :In a recent survey, two thirds of health providers self-reported not being very comfortable answering HPV-related questions [25]; the same problem exists for discussing other STDs with patients [26]. Furthermore, research shows that knowledge relevant for patient counseling is not sufficient in general practitioners [27,28]. This may have several causes.
Knowledge about infection with human papillomavirus: A systematic review
2008, Preventive MedicineCitation Excerpt :A more valid picture of knowledge is obtained if the subjects must produce an answer themselves (Schuman and Presser, 1979). In this review, only physicians showed a high percentage of knowledge in response to an open question (Martinez et al., 1997; Baay et al., 2006). The second predictor was gender.
Pediatrician knowledge and attitudes regarding human papillomavirus disease and its prevention
2007, VaccineCitation Excerpt :As in the case of any new vaccine, the implementation of HPV vaccines gives rise to problems such as a lack of confidence in their efficacy, the fear of side effects, and purchase costs [22,23]. However, HPV vaccines may face additional barriers because they are intended to prevent a sexually transmitted disease, because the relationship between HPV infection and the development of cancer many years later is underestimated, and because their efficacy in preventing malignancies other than cervical cancer is still unknown [24–28]. Furthermore, it is also unknown whether other oncogenic types might replace types 16 and 18 after the introduction of HPV vaccines, and whether the vaccines are effective in immunocompromised subjects [29,30].
