Two hundred and forty-five women consecutively attending a large city Sexually Transmitted Diseases (STD) Centre had routine cervical screening performed by both the Pap smear and, in addition, a Cervigram. The aim of this study was to determine the prevalence of HPV infection, CIN and cervical cancer in an STD population. The mean age of this group was 26 years with a range from 16 to 53 years. Colposcopy and biopsy revealed a prevalence for human papillomavirus (HPV) of 41%, and 20.4% for cervical intraepithelial neoplasia (CIN). No cases of cervical cancer were detected. The Pap smear detected HPV-associated change in 18% and CIN in 8.2%, therefore generally underestimating the true prevalence of HPV and CIN. Cervicography was positive in 44% of the total group, indicating either HPV-associated change or CIN. Current screening methods are therefore failing to detect significant amounts of HPV-associated change and CIN.  相似文献

ObjectiveTo find out different grades of cervical intraepithelial lesions of cervix with visual inspection of cervix with acetic acid (VIA).MethodsVIA was carried out in 540 eligible women attending Gynaecology Outpatient Department for gynecological problems. The women underwent a complete clinical evaluation. All screened women (540) were evaluated by colposcopy and biopsies which were taken from different quadrants of the cervix. The final diagnosis was based on histology, which allowed direct estimation of sensitivity, specificity, and predictive values of VIA and colposcopy. Those with abnormal lesions diagnosed by histology were considered as true positive.ResultsOut of 540 patients screened, 212 (39.27%) were VIA positive. More patients with cervical lesions were detected by VIA than colposcopy. There were 63 (11.67%) women with histologic cervical intraepithelial neoplasia (CIN I), which was found in 150 (27.78%) by VIA and 138 (25.56%) by colposcopy. VIA and colposcopy yielded high grade CIN II in the same number of patients. Biopsy proven cancer was found in 24 (4.45%) which was detected in 18 (3.33%) by VIA and colposcopy. Sensitivity and specificity of VIA were 68.50% and 70.45% respectively. Positive predictive value was 41.04% and negative predictive value was 90.85%.ConclusionsVIA can differentiate a normal cervix from a precancerous cervix with reasonable accuracy. The sensitivity and specificity of VIA are comparable to the other studies. So VIA may reduce the cervical intraepithelial lesions both in urban and rural areas.  相似文献

The reduction of cervical cancer mortality in developing countries is only one of many priorities competing for scarce funds. Incidence of cervical cancer may be up to six times higher in these countries than in developed countries due to lack of screening programs. The current WHO recommendation is to evaluate visual inspection as a way of identifying early curable cancer, as screening by cytology is too complex and expensive. Hence, an assessment of visual inspection aided by acetic acid (VIA) has been conducted in Zimbabwe. The study aimed to find out the true sensitivity, specificity, and positive predictive value (PPV) for high-grade CIN. The subject group was composed of 10,934 women screened by VIA and by exfoliative cervical cytology. The main findings of the study were that VIA was abnormal in about 20% of women; moreover, the test had a PPV of 25.9%, meaning that 3 out of 4 women would potentially be overtreated. VIA, however, represents a proven, simple means of identifying women in undeveloped health facilities, though level of training is probably critical to its success. Screening should go hand in hand with health education, which has proven valuable in reducing the rate of deaths from cervical cancer.  相似文献

India is a high-risk country for cervical cancer which accounts a quarter (126,000 new cases, 71,000 deaths around 2,000) of the world burden. The age-standardized incidence rates range from 16-55 per 100,000 women in different regions with particularly high rates in rural areas. Control of cervical cancer by early detection and treatment is a priority of the National Cancer Control Programme of India. There are no organized cytology screening programmes in the country. The technical and financial constraints to organize cytology screening have encouraged the evaluation of visual inspection approaches as potential alternatives to cervical cytology in India. Four types of visual detection approaches for cervical neoplasia are investigated in India: a) naked eye inspection without acetic acid application, widely known as 'downstaging'; b) naked eye inspection after application of 3-5% acetic acid (VIA); c) VIA using magnification devices (VIAM); d) visual inspection after the application of Lugol's iodine (VILI). Downstaging has been shown to be poorly sensitive and specific to detect cervical neoplasia and is no longer considered as a suitable screening test for cervical cancer. VIA, VIAM and VILI are currently being investigated in multicentre cross-sectional studies (without verification bias), in which cytology and HPV testing are also simultaneously evaluated, and the results of these investigations will be available in 2003. These studies will provide valuable information on the average, comparative test performances in detecting high-grade cervical cancer precursors and cancer. Results from pooled analysis of data from two completed studies indicated an approximate sensitivity of 93.4% and specificity of 85.1% for VIA to detect CIN 2 or worse lesions; the corresponding figures for cytology were 72.1% and 91.6%. The efficacy of VIA in reducing incidence of an mortality from cervical cancer and its cost-effectiveness is currently being investigated in two cluster randomized controlled intervention trials in India. One of these studies is a 4-arm trial addressing the comparative efficacy of VIA, cytology and primary screening with HPV DNA testing. This trial will provide valuable information on comparative detection rates of CIN 2-3 lesions by the middle of 2003. The expected outcomes from the Indian studies will contribute valuable information for guiding the development of public health policies on cervical cancer prevention in countries with different levels of socio-economic and health services development and open up new avenues of research.

Evidence for the clinical utility of human papillomavirus (HPV) DNA testing has increased over the years and has now become very convincing. Some specific uses of HPV detection are a) triage of women with cytological determinations of atypical squamous cells of undetermined significance (ASC-US) and related management strategies, b) as a marker for test of cure post-treatment, and c) most importantly, as an adjunct to cytology in routine cervical disease screening programs. There are many studies that support each of these applications and include 8 studies on ASC-US triage, 10 on test of cure and 13 on adjunctive or stand-alone HPV screening. The most notable investigation of ASC-US triage was ALTS, a randomized controlled trial of 3,488 women. With respect to routine HPV screening the combined studies included 77,000 women, providing as a histological endpoint more than 1,000 cases of high-grade cervical intraepithelial neoplasia (CIN) or cancer. Testing methods were either the Hybrid Capture 2 (HC2) test or the polymerase chain reaction (PCR) test. HPV testing of women with ASC-US cytology had on average a higher sensitivity (90%) and specificity (70%) than repeating the cytological test (sensitivity 75%, specificity 60%) and was also more sensitive than colposcopy for follow-up. As an adjunct to the Papanicolaou (Pap) cytology test in routine screening, HPV DNA testing was a more sensitive indicator for prevalent high-grade CIN than either conventional or liquid cytology. A combination of HPV DNA and Papanicolaou testing had almost 100% sensitivity and negative predictive value. The specificity of the combined tests was slightly lower than the specificity of the Papanicolaou test. One "double-negative" HPV DNA and Papanicolaou test indicated a higher prognostic assurance against risk of future CIN 3 than three subsequent negative conventional Papanicolaou tests and may safely allow three-year or longer screening intervals for such low-risk women. It appears that HPV DNA testing is on the way to becoming a common testing strategy in cervical cancer prevention programs. Research continues into approaches for improving the performance and cost-effectiveness of HPV detection methods. Hybrid Capture 3 will offer improved HPV typing capabilities and the Rapid Capture machine allows for robot-assisted HPV DNA testing, permitting greater test throughput. PCR test improvements are expected to contribute to the growth of flexible accurate and cost-effective HPV DNA tests. It is likely that improved diagnostic technology along with HPV genotyping and quantitation may provide more value in future. A particularly promising approach is to combine HPV DNA testing with expression levels of other markers such as proliferative or cell cycle regulatory proteins to subdivide HPV-positive women into those who are at greater risk of cancer and those who can be safely followed by screening at longer intervals.

OBJECTIVE: To compare visual inspection with acetic acid (VIA) to Papanicolau (PAP) smears in a community setting in a developing nation. METHODS: Women undergoing cervical cancer screening in Honduras received either VIA and PAP smears (VIA/PAP group) or PAP smears alone (PAP-only group). Local healthcare providers performed PAP screening. A VIA-trained nurse performed VIA exams. All PAP smears were processed in Honduras. PAP smears from the VIA/PAP group were reviewed in the United States. Women with positive VIA or PAP tests were offered colposcopy. We compared the relative accuracy of PAP smears and VIA and the proportions of women completing follow-up colposcopy after positive screening tests. RESULTS: In total, 1709 PAP smears were performed including women from both the VIA/PAP and PAP-only groups. Nine PAP smears were positive (0.5%). Three women completed colposcopy (33%). All three had biopsy-confirmed dysplasia. In the VIA/PAP group (n = 339), 49 VIA exams were abnormal (14%) and two PAP smears were abnormal when read in Honduras (0.6%). When reviewed in the United States, 14 of the 339 PAP smears were abnormal (4%). Forty women (83%) completed follow-up colposcopy after a positive VIA exam. Twenty-three had biopsy-proven dysplasia. All 23 dysplasia cases had negative PAP smear readings in Honduras; four PAP smears were reclassified as positive in the United States. CONCLUSIONS: Although few developing countries can maintain high-quality PAP smear programmes, many governments and charitable organizations support cervical cancer screening programmes that rely on PAP smears. This study underscores the need to promote alternative technologies for cervical cancer screening in low-resource settings.  相似文献

Background:Early detection and diagnosis of high-grade cervical intraepithelial neoplasia grade 2 or higher (CIN2+) is critical for a good prognosis and appropriate treatment. The chief aim of our study was to evaluate the diagnostic performance of folate receptor-mediated staining solution detection (FRD) for CIN2+.Methods:We conducted a systematic review and meta-analysis by searching the PubMed and EMBASE databases for studies published until May 2020, which assessed the diagnostic accuracy of FRD, human papilloma virus (HPV) testing, and ThinPrep cytology test (TCT) for the detection of CIN2+. Bivariate models were used to compare the diagnostic performance of FRD, HPV, and TCT.Results:Six studies involving 2817 patients were included in this meta-analysis. The pooled specificity of FRD was higher than that of HPV and TCT for detecting CIN2+ (0.65, 0.12, and 0.39, respectively). The summary area under the receiver operating characteristic curve values using FRD, HPV, and TCT for detecting CIN2+ were 0.79, 0.95, and 0.77, respectively, indicating that FRD was superior to TCT. The diagnostic odds ratios of FRD, HPV, and TCT were 6 (95% CI: 5–7), 3 (95% CI: 2–5), and 3 (95% CI: 2–4), respectively, demonstrating that FRD had good diagnostic accuracy.Conclusion:FRD showed good diagnostic accuracy and higher specificity than HPV and TCT for detecting CIN2+. Based on our results, we propose that FRD could be a candidate for cervical screening, especially in underdeveloped countries.  相似文献
