Screening for cervical cancer: a review of women's attitudes, knowledge, and behaviour. (1/2075)

The United Kingdom (UK) cervical screening programme has been successful in securing participation of a high proportion of targeted women, and has seen a fall in mortality rates of those suffering from cervical cancer. There remains, however, a significant proportion of unscreened women and, of women in whom an abnormality is detected, many will not attend for colposcopy. The present work reviews the psychological consequences of receiving an abnormal cervical smear result and of secondary screening and treatment, and examines reasons for women's non-participation in the screening programme. Psychological theories of screening behavior are used to elucidate women's reactions and to suggest methods of increasing participation, of improving the quality of the service, and of reducing women's anxiety. A literature search identified studies that examine factors influencing women's participation in the screening programme, their psychological reaction to the receipt of an abnormal cervical smear result, and experiences of colposcopy. Reasons for non-participation include administrative failures, unavailability of a female screener, inconvenient clinic times, lack of awareness of the test's indications and benefits, considering oneself not to be at risk of developing cervical cancer, and fear of embarrassment, pain, or the detection of cancer. The receipt of an abnormal result and referral for colposcopy cause high levels of distress owing to limited understanding of the meaning of the smear test; many women believe the test aims to detect existing cervical cancer. The quality of the cervical screening service can be enhanced by the provision of additional information, by improved quality of communication, and by consideration of women's health beliefs. This may result in increased participation in, and satisfaction with, the service.  (+info)

Natural history of dysplasia of the uterine cervix. (2/2075)

BACKGROUND: A historical cohort of Toronto (Ontario, Canada) women whose Pap smear histories were recorded at a major cytopathology laboratory provided the opportunity to study progression and regression of cervical dysplasia in an era (1962-1980) during which cervical squamous lesions were managed conservatively. METHODS: Actuarial and Cox's survival analyses were used to estimate the rates and relative risks of progression and regression of mild (cervical intraepithelial neoplasia 1 [CIN1]) and moderate (CIN2) dysplasias. In addition, more than 17,000 women with a history of Pap smears between 1970 and 1980 inclusive and who were diagnosed as having mild, moderate, or severe dysplasia were linked to the Ontario Cancer Registry for the outcome of any subsequent cervical cancers occurring through 1989. RESULTS: Both mild and moderate dysplasias were more likely to regress than to progress. The risk of progression from mild to severe dysplasia or worse was only 1% per year, but the risk of progression from moderate dysplasia was 16% within 2 years and 25% within 5 years. Most of the excess risk of cervical cancer for severe and moderate dysplasias occurred within 2 years of the initial dysplastic smear. After 2 years, in comparison with mild dysplasia, the relative risks for progression from severe or moderate dysplasia to cervical cancer in situ or worse was 4.2 (95% confidence interval [CI] = 3.0-5.7) and 2.5 (95% CI = 2.2-3.0), respectively. CONCLUSION: The risk of progression for moderate dysplasia was intermediate between the risks for mild and severe dysplasia; thus, the moderate category may represent a clinically useful distinction. The majority of untreated mild dysplasias were recorded as regressing to yield a normal smear within 2 years.  (+info)

Pap screening clinics with native women in Skidegate, Haida Gwaii. Need for innovation. (3/2075)

PROBLEM ADDRESSED: First Nations women in British Columbia, especially elders, are underscreened for cancer of the cervix compared with the general population and are much more likely to die of the disease than other women. OBJECTIVE OF PROGRAM: To develop a pilot program, in consultation with community representatives, to address the Pap screening needs of First Nations women 40 years and older on a rural reserve. MAIN COMPONENTS OF PROGRAM: Identification of key links to the population; consultation with the community to design an outreach process; identification of underscreened women; implementation of community Pap screening clinics; evaluation of the pilot program. CONCLUSIONS: We developed a Pap screening outreach program that marked a departure from the usual screening approach in the community. First Nations community health representatives were key links for the process that involved family physicians and office staff at a local clinic on a rural reserve. Participation rate for the pilot program was 48%, resulting in an increase of 15% over the previously recorded screening rate for this population. More screening clinics of this type and evaluation for sustainability are proposed.  (+info)

Mildly dyskaryotic smear results: does it matter what women know? (4/2075)

BACKGROUND: As of 1992, all women in the UK who have a first mildly dyskaryotic cervical smear are placed under surveillance for 6 months rather than being referred for immediate colposcopy. OBJECTIVES: We aimed to explore the relationship between anxiety and understanding about mild dyskaryotic, and to propose and discuss a method of analysing free text comments written by participants in studies based on structured questionnaires. METHODS: The freely scripted text of 236 women who had completed a questionnaire as part of a randomized controlled trial to assess the impact of an educational package was analysed. Randomization group status was concealed. Texts expressing similar views were grouped together and categorized. A matrix was drawn up to encompass the categories, and the comments were reallocated accordingly. RESULTS: Examination of the free text revealed two dimensions, concern and knowledge. There were no differences with respect to the apparent level of concern between the two randomization groups. However, comments from the intervention group were significantly more likely to have been classified as expressing good or vague knowledge than those from women in the control group. CONCLUSION: Although the educational intervention improved women's knowledge about the meaning of an abnormal smear result, this better knowledge was not correlated with less anxiety about the result. The free text analysis was a useful supplement to the main trial questionnaires. It demonstrated the existence of a range of understanding about cervical dyskaryosis, of anxieties relating to the receipt of such a result and the degree of interest women showed in acquiring further information.  (+info)

A mobile unit: an effective service for cervical cancer screening among rural Thai women. (5/2075)

BACKGROUND: We carried out a systematic screening programme using a mobile unit with the purpose of increasing use of Papanicolaou (Pap) smear screening among rural Thai women. The mobile unit campaign was carried out initially between January and February 1993 and then in 1996 in all the 54 rural villages in Mae Sot District, Tak Province, northern Thailand. METHODS: To evaluate the effect of the programme on changes in knowledge and use of screening, we compared the results of three interview surveys of women, 18-65 years old, in villages selected by systematic sampling for each survey; first in 1991 (before the operation of the programme), secondly in 1994 (one year after the first screening campaign), and last in 1997 (one year after the second campaign). This report also compares data on Pap smears taken by the mobile unit with other existing screening services in the study area. RESULTS: A total of 1603, 1369, and 1576 women respectively, participated in each survey. The proportion of women reported knowing of the Pap smear test increased from 20.8% in 1991 to 57.3% in 1994 and to 75.5% in 1997. The proportion of women who had ever had a Pap smear increased from 19.9% in 1991 to 58.1% in 1994 and to 70.1% by 1997. Screening by the mobile unit accounted for 85.2% of all cervical intraepithelial neoplasia (CIN) III and all invasive cancers identified among the Pap smears taken by screening services in the area between 1992 and 1996. The rate of CIN III was 3.5/1000 smears in this screening programme, which was 5.2 and 2.0 times higher than the rates in the maternal and child health/family planning clinic and the annual one-week mass screening campaign respectively. CONCLUSIONS: The use of a mobile unit may be an effective screening programme in rural areas where existing screening activities cannot effectively reach the female population at risk.  (+info)

Comparison between virus isolation method, Papanicolaou stain, immunoperoxidase stain and polymerase chain reaction in the diagnosis of genital herpes. (6/2075)

Papanicolaou (Pap) stain, immunoperoxidase (IP) stain and polymerase chain reaction (PCR) were evaluated against the virus isolation method for their sensitivity and specificity in the diagnosis of herpes simplex virus (HSV) infection in 96 women who were suspected of genital herpes. The result showed that the sensitivity of PCR, IP and Pap stain was 100, 92.0 and 62.7%, respectively, while the specificity was 76.2, 66.7 and 81.0%, respectively. PCR was even more sensitive than the virus isolation technique. As Pap stain is the technique routinely performed for diagnosing genital herpes in most of the hospitals in Thailand, its low sensitivity should be taken into consideration. Based on the investigation by all four techniques together, HSV infection was diagnosed in 91.6% of the cases suspected of genital herpes which reflected higher precision of the clinical diagnosis over Pap stain.  (+info)

Association of human papillomavirus infection and disease with magnitude of human immunodeficiency virus type 1 (HIV-1) RNA plasma level among women with HIV-1 infection. (7/2075)

Ninety-three women with human immunodeficiency virus type 1 (HIV-1) infection were enrolled in a cross-sectional study to evaluate the relationship between plasma HIV-1 RNA levels and coincident cervical infection and disease caused by human papillomaviruses (HPVs). HIV-1 RNA plasma levels of >10,000 copies/mL were highly associated with the presence in cervical specimens of HPV DNA of oncogenic (high risk) virus genotypes (P=.006; relative risk, 2.57). In addition, similar HIV-1 RNA plasma levels were associated with abnormal Pap smears (P=.01; relative risk, 2.11). In this study, 81% of women with high-risk HPV cervical infection had abnormal Pap smears. Measurement of HIV-1 RNA plasma levels may help to identify a subgroup of HIV-1-infected women at increased risk for cervical HPV infection and disease.  (+info)

Nonisotopic detection and typing of human papillomavirus DNA in genital samples by the line blot assay. The Canadian Women's HIV study group. (8/2075)

The line blot assay, a gene amplification method that combines PCR with nonisotopic detection of amplified DNA, was evaluated for its ability to detect human papillomavirus (HPV) DNA in genital specimens. Processed samples were amplified with biotin-labeled primers for HPV detection (primers MY09, MY11, and HMB01) and for beta-globin detection (primers PC03 and PC04). Amplified DNA products were hybridized by a reverse blot method with oligonucleotide probe mixtures fixed on a strip that allowed the identification of 27 HPV genotypes. The line blot assay was compared to a standard consensus PCR test in which HPV amplicons were detected with radiolabeled probes in a dot blot assay. Two hundred fifty-five cervicovaginal lavage specimens and cervical scrapings were tested in parallel by both PCR tests. The line blot assay consistently detected 25 copies of HPV type 18 per run. The overall positivity for the DNA of HPV types detectable by both methods was 37.7% (96 of 255 samples) by the line blot assay, whereas it was 43. 5% (111 of 255 samples) by the standard consensus PCR assay. The sensitivity and specificity of the line blot assay reached 84.7% (94 of 111 samples) and 98.6% (142 of 144 samples), respectively. The agreement for HPV typing between the two PCR assays reached 83.9% (214 of 255 samples). Of the 37 samples with discrepant results, 33 (89%) were resolved by avoiding coamplification of beta-globin and modifying the amplification parameters. With these modifications, the line blot assay compared favorably to an assay that used radiolabeled probes. Its convenience allows the faster analysis of samples for large-scale epidemiological studies. Also, the increased probe spectrum in this single hybridization assay permits more complete type discrimination.  (+info)
