OBJECTIVE: We evaluated the contribution of the human papilloma virus (HPV) load in planning follow-up and management of women post cone biopsy for high-grade cervical intraepithelial neoplasia (CIN2-3). METHODS: Ninety-six suitable women were followed-up by Pap smears: two consecutive abnormal smears dictated referral for colposcopy-directed biopsy. Before colposcopy, HPV tests determined high-risk HPV DNA type and load (Hybrid Capture System type I). Patients histologically diagnosed with CIN1 or CIN2-3 underwent repeat conization or hysterectomy for residual disease. HPV load was compared to cytology for the detection of residual disease. RESULTS: At follow-up, 20/89 (22.4%) studied women had positive cytology reports of either low- (n = 11) or high-grade (n = 9) squamous intraepithelial lesion (SIL). Colposcopic biopsies diagnosed 9 CIN1 and 8 CIN2-3 cases. Residual disease was corroborated in 16/17 (94.1%) women and the status was readjusted based on cone biopsy/hysterectomy: CIN2-3 in 9 and CIN1 in 7. The positive prediction values for CIN2-3 residual disease with high-grade SIL, CIN2-3 on colposcopic punch biopsy, and high HPV load were 89, 100, and 100%, respectively. For CIN1 residual disease with low-grade SIL, CIN1 on colposcopic punch biopsy, and low and borderline HPV load, they were 54.5, 77.7, and 100%. The HPV load was a more accurate predictor for CIN1 or CIN2-3 on the cervical specimen in cases with low-grade SIL or CIN1 on colposcopic biopsy. CONCLUSIONS: Evaluating HPV loads after a positive cytology report may assist in triaging women post conization biopsy for CIN2-3 to appropriate treatment. Its high positive predictive value, specificity, and sensitivity for CIN1 and CIN2-3 and supplementary information could be especially pertinent for clinical management of low-grade SIL cases. 相似文献

OBJECTIVE: The objective of this study was to evaluate the clinical and economic implications of adding human papillomavirus (HPV) testing to the follow-up and management protocol of women with a histological diagnosis of low-grade cervical intraepithelial neoplasia (CIN1). METHODS: The study cohort consisted of 314 women with histological diagnosis of CIN1 and who met the inclusion criteria. They were followed-up by pap smears and samples for HPV tests that were obtained and analyzed on the first visit after referral. HPV assessment was carried out later. Colposcopy and biopsies were performed when there were two consecutive abnormal pap results or positive HPV tests. Women with any degree of CIN underwent cone biopsies. RESULTS: The positive predictive value (PPV) of low-grade squamous intraepithelial lesion and high-grade squamous epithelial lesion to identify high-grade lesions (CIN2-3) were 48.9 and 95%, respectively. The PPV of low-risk HPV type for CIN1 and that of high-risk HPV type for CIN2-3 were both 97%. Of the 314 study participants, 68 (21.6%) patients were positive for HPV analysis, and 67 of these (98.5%) had either CIN1 or CIN2-3 on the cone biopsy, with an overall PPV of 95%. The cost effectiveness ratio was $1457 per additional case detected by the "HPV approach." CONCLUSIONS: Testing for the presence of high-risk HPV types is both clinically and economically more beneficial than cytology in the follow-up and management of patients with a diagnosis of CIN 1 because of its better sensitivity, specificity, and PPV reports. 相似文献

A comparison of the human papillomavirus test and Papanicolaou smear as a second screening method for women with minor cytological abnormalities 总被引:2,自引:0,他引:2
Andersson S Dillner L Elfgren K Mints M Persson M Rylander E 《Acta obstetricia et gynecologica Scandinavica》2005,84(10):996-1000
BACKGROUND: Of the estimated one million Papanicolaou (pap) smears performed annually in Sweden, about 4% show any degree of abnormality. Approximately, 1% of these cases contain moderate or severe atypia (high-grade squamous intraepithelial lesions) and the rest contain low-grade atypia. Recommendations for the management of minor abnormalities vary in various parts of Sweden. Generally, a second Pap smear is obtained 4-6 months after the first one showing low-grade atypia. The aim of this study is to compare the sensitivity of human papilloma virus (HPV)-DNA testing for the detection of cervical intraepithelial neoplasia (CIN) 2-3 with that of a second Pap smear in women, who had low-grade atypia in their first Pap smear. METHODS: Women with low-grade atypia in the Stockholm area, detected at a population-based cytology screening, were enrolled. A repeat Pap smear, HPV test, and colposcopically directed biopsies were obtained. For the detection of HPV, Hybrid Capture II (HC II) was used. RESULTS: The HPV-DNA test was positive in 66% of the 177 participating women. The sensitivity of the second Pap smear and HPV-DNA test to detect CIN 2-3 was 61 (95% CI = 45-74) and 82% (95% CI = 67-91), respectively. The positive and negative predictive values of HPV testing were 27 (95% CI = 18-35) and 89% (95% CI = 80-97), respectively. CONCLUSIONS: In Sweden, a second Pap smear is often obtained for the follow-up of women with low-grade atypia. The results of our study show that compared to the second Pap smear, HPV testing with HC II is a more sensitive method for detecting high-grade lesions. 相似文献

Negative predictive value of human papillomavirus test following conization of the cervix uteri. 总被引:17,自引:0,他引:17
OBJECTIVE: The goal of this study was to determine/evaluate the negative predictive value of human papillomavirus (HPV) testing following conization of cervix uteri. METHODS: A prospective analysis was undertaken on 79 cone biopsies of women with high-grade lesions (cervical intraepithelial neoplasia (CIN) III). HPV testing was performed on cervical smears before and after conization. We correlated the margin status (defined as positive cone margin or endocervical curettage status) and positive conization HPV status with the residual disease in a hysterectomy specimen. A Digene II kit was used to perform HPV testing. HPV detection was done by Hybrid Capture assay. RESULTS: Of the 79 patients, 47(59.5%) had positive margins after conization. HPV testing was positive in 37 cases (78.7%) and negative in 10 cases (21.3%). Residual disease was found in 31 of 47 (66%) postconization hysterectomy specimens. No residual lesions were found in HPV-negative cases. Of the 32 cases with negative margins following conization, HPV testing was negative in 25 cases (78%) and was positive in 7 cases (22%). Among these 25 cases with negative HPV tests, no residual lesion was detected, and in 7 HPV-positive cases, only one residual lesion was found. CONCLUSION: HPV testing is potentially an effective tool in predicting residual dysplasia after conization and could potentially assist in the decision between hysterectomy and conservative follow-up in women with CIN III. 相似文献

We aimed to investigate whether postconization human papillomavirus (HPV) DNA testing can predict treatment failure and improve the accuracy of conventional follow-up in women with high-grade cervical intraepithelial neoplasia (CIN). Between March 2001 and October 2005, 120 patients with confirmed CIN 2 or 3 were treated with loop electrosurgical excision procedure (LEEP) and were enrolled. Six patients were lost to the follow-up. Postconization follow-up was performed at every 3-6 months during the first year and then annually. Specimens were tested for the presence of HPV, using the Hybrid Capture 2 (Digene Co, Gaithersburg, MD) and HPV DNA chip (Mygene Co, Seoul, Korea) test. Persistent HPV infection was defined as persistently (two times or more) positive HPV tests with the same HPV subtype(s) at initial diagnosis. Twenty-two (19.3%) patients showed treatment failure after conization. The only significant risk factor for redevelopment of CIN after conization was persistence of the same HPV subtype (P < 0.0001). And women with recurrent or residual CIN had higher HPV load during the 6-month follow-up postconization. In conclusion, the persistence of the same HPV subtype after LEEP conization was an important predictor of treatment failure. The follow-up protocol after conization of CIN should include both cervical cytology and HPV test, and HPV DNA chip test is needed to detect a persistent HPV infection. 相似文献

OBJECTIVE: We aimed to define the adjunctive role of human papillomavirus (HPV) DNA testing in the follow-up of high-grade cervical intraepithelial neoplasia (CIN) after conization. STUDY DESIGN: We analyzed a consecutive series of 2,154 patients who received conization. Patients who had cone diagnosis of cervical cancer or CIN 1, a hysterectomy within 12 weeks after conization, and no follow-up data were excluded. The remaining 765 patients (monitored by Pap smears, colposcopy with or without high-risk HPV DNA testing) were analyzed. RESULTS: Of the 765 patients, 279 had CIN at cone margin or endocervix (group A) while 486 were both margin- and endocervix-free (group B). The 3-year cumulative rate of residual/recurrent high-grade CIN was 10.3% (95% CI, 6.9-13.7). HPV follow-up status (P=.015), margin status (P=.001), and follow-up cervical cytology (P<.0001) were significant predictors for residual/recurrent high-grade CIN by multivariate analysis. Four high-grade CINs and 1 microinvasive carcinoma of group A were detected initially by HPV testing, while 48.3% (199/410) of those without recurrent/persistent high-grade CIN still had persistent HPV infection. CONCLUSION: HPV DNA testing is useful in the follow-up and understanding of the natural history after conization for high-grade CIN. 相似文献

Background: A Pap test result of atypical squamous cells of undetermined significance (ASCUS) presents a clinical challenge. Only 5–10% of women with ASCUS harbour serious cervical disease.
Methods: We screened 3619 women, who attended to Mirza Koochak Khan Hospital at Tehran University of Medical Sciences with Pap smears, of whom 100 returned with ASCUS. After six months, each subject underwent a standard cytology (conventional Pap smear), human papillomavirus (HPV) DNA testing (identifying high-risk HPV types with polymerase chain reaction) and colposcopy with multiple cervical biopsies.
Results: Mean age was 44.09 ± 8.6 years. The estimated prevalence of cervical intraepithelial neoplasia (CIN) II or higher was 4%. When histologically verified high-grade lesions (≥ CIN II) were observed, the relative sensitivity of HPV DNA testing was 100% compared with conventional Pap smear, which performed 75% versus 100% relative sensitivity, respectively, using cytological diagnosis high-grade squamous intraepithelial lesion, or low-grade squamous intraepithelial lesion (LSIL) as the cut-off. Negative and positive predictive values (NPV and PPV) of Pap test were 98.9% and 100%. The NPV and PPV of HPV DNA testing were 100%.
Conclusions: Although less complicated than colposcopy, the repeat Pap smear triage algorithm for ASCUS may underdiagnose some women with high-grade CIN, when compared with colposcopy. Considering the high sensitivity of HPV testing, it may be useful as an alternative to the current policy of six-month repeat cytology for women with ASCUS results. 相似文献

OBJECTIVE: To explore the role of high-risk human papillomavirus (HPV) DNA testing in the improvement of the recognition of cervical cancer and precancerous lesions in women with abnormal cervical cytology. METHODS: A total of 2152 women with abnormal cervical cytology were submitted to both HPV DNA testing and biopsy guided by colposcopy and the results were correlated. RESULTS: Positive rate of high-risk HPV DNA in groups of atypical squamous cells of undetermined significance (ASC-US), atypical squamous cells, cannot exclude high-grade (ASC-H), low-grade squamous intraepithelial lesions and high-grade squamous intraepithelial lesions was 53.7, 53.2, 84.6 and 93.0%, respectively. In each group, the detection rate of grade 2,3 cervical intraepithelial neoplasia (CIN 2,3) or cervical cancer in patients with positive HPV DNA was significantly higher than that with negative HPV DNA (P<0.05). In ASC-US group, the negative predictive value of high-risk HPV DNA testing for detection of CIN 2,3 and cervical cancer was 99.8% and the sensitivity 98%. CONCLUSION: HPV DNA testing is a useful indicator in the management of patients with ASC-US and plays an important role in the evaluation of risk for CIN 2,3 and cervical cancer. 相似文献

OBJECTIVE: To compare current cytological follow up of women treated for high-grade cervical intraepithelial neoplasia (CIN) with follow up by high-risk human papillomavirus (HPV) testing together with cytology. DESIGN: A cost-effectiveness modelling study. SETTING: Gynaecology clinics in the Netherlands. POPULATION: Women treated for high-grade CIN. METHODS: A Markov model was developed to compare six follow-up strategies with HPV testing with current cytological follow up at 6, 12, and 24 months. Model parameter estimation was based on three Dutch follow-up studies and a Dutch population-based screening cohort. MAIN OUTCOME MEASURES: The number of CIN2/3 cases missed after 5 years follow up, the number of diagnostic procedures, and costs involved. RESULTS: Strategies with adjunct HPV testing were more effective than current follow up (reduction in missed CIN2/3 cases 32-77%, corresponding to a number needed to treat of 192-455) and less inconvenient (reduction in repeat smears 28-65%). A particularly attractive strategy was HPV testing alone at 6 months and both HPV and cytological testing at 24 months after treatment. This strategy yielded a high detection rate of post-treatment CIN, did not lead to an increase in colposcopy rate, and was 49 Euro per woman cheaper than the current strategy. CONCLUSIONS: Our model supports the use of high-risk HPV testing for monitoring women treated for high-grade CIN. 相似文献

To assess the performance of human papillomavirus (HPV) testing and colposcopy in detection of cervical pathology. A series of 389 women referred for colposcopy due to an abnormal Pap smear had cervical swabs analyzed for oncogenic (high-risk [HR]) HPV types using Hybrid Capture II (HC2) assay. Loop electrical excision procedure cone biopsy (88%) or colposcopic biopsy (11%) was used as the gold standard. Of the atypical squamous cells of undetermined significance (ASCUS) smears, 48% were positive for HR HPV, as compared to 76.3% of low-grade squamous intraepithelial lesions (LSIL) smears. HR HPV was detected in 66.7% and 90% of patients with cervical intraepithelial neoplasia (CIN) 1 and CIN2 (or higher), respectively. The sensitivity of the Pap smear using an ASCUS threshold in detecting high-grade CIN was 94.5% (95% confidence intervals (CI): 91-97%) and that of colposcopy 98.5% (95% CI: 95-99%). The respective specificities were 30% (95% CI: 17-28%) and 35.6% (CI: 29-42%). HC2 test had comparable sensitivity, 90% (95% CI: 85-93%), but higher specificity, 54.3% (95% CI: 47-61%). Combining HC2 test with Pap increased specificity, 66.7% and 41.3% for ASCUS and LSIL cutoff, respectively. The minor-abnormality threshold together with HC2 increased specificity of colposcopy with no changes in sensitivity. High viral load (>100 relative light unit/positive control) was associated with significant disease. HPV DNA testing improves the accuracy of colposcopy in the detection of high-grade CIN in women with ASCUS or LSIL smears. 相似文献

OBJECTIVE: This study was undertaken to compare postcolposcopy management strategies for women referred for low-grade squamous intraepithelial lesions (LSIL) or oncogenic human papillomavirus (HPV) DNA-positive atypical squamous cells of undetermined significance (ASCUS), with cervical intraepithelial neoplasia (CIN) grade 1 or less found at initial colposcopy. STUDY DESIGN: A 2-year prospective follow-up of 1539 women was designed to assess the percentage sensitivity of different postcolposcopy management strategies to detect subsequent CIN grade 2 or 3 and percentage referral to repeat colposcopy. RESULTS: HPV testing at 12 months was sensitive (92.2%) for detection of CIN grade 2 or 3 with a referral rate to repeat colposcopy of 55.0%. Repeat semiannual cytology with referral to colposcopy at an ASCUS threshold demonstrated similar sensitivity (88.0%) but with a higher rate of referral to colposcopy (63.6%). Combining cytology and HPV testing did not increase sensitivity and hurt specificity. Baseline viral load and colposcopic impression were not helpful. CONCLUSION: The most efficient test for identifying women with CIN grade 2 or 3 after colposcopy might be an HPV test alone at 12 months. 相似文献

Objective: To determine the frequency of high-grade cervical intraepithelial neoplasia in patients with atypical and low-grade cervical cytology and to assess the optimal evaluation and follow-up.Methods: Prospective observational study of 367 of 7,651 private patients who had cytologic, virologic, or colposcopic changes suggesting cervical intraepithelial neoplasia or cervical carcinoma. The study was performed to determine the frequency of cervical intraepithelial neoplasia in the various cytologic groups and to assess the effect of testing for human papillomavirus on the sensitivity, specificity, and positive predictive value of these tests.Results: Papanicolaou smears that included all non-negative tests (high- and low-grade squamous intraepithelial lesions and atypical squamous or glandular epithelial cells of undetermined significance) had the maximal sensitivity (89%) for high-grade cervical intraepithelial neoplasia and cancer. The combined cytologic categories of high- and low-grade squamous intraepithelial lesions had a sensitivity of 58%, this was reduced to 24% if only high-grade squamous intraepithelial lesions were considered relevant for additional evaluation. If we had not evaluated the patients with atypical squamous and glandular cells of undetermined significance, we would have missed diagnosing one third of high-grade and one half of low-grade cervical intraepithelial neoplasia. Cervical cytology was false negative in 8% of patients with high-grade and in 14% of those with low-grade cervical intraepithelial neoplasias. High-risk human papillomavirus deoxyribonucleic acid was detected in 40% of women with high-grade and in 24% of those with low-grade grade cervical intraepithelial neoplasias. The positive predictive value of cytology with atypical squamous cells of undetermined significance increased from 5% to 38% for high-grade and from 30 to 85% for high- and low-grade cervical intraepithelial neoplasias in patients with detectable high-risk human papillomavirus deoxyribonucleic acid. Virologic studies produced no significant improvement on these diagnoses in women with high- or low-grade cytology.Conclusions: Because of the poor sensitivity of cytology suggesting high-grade squamous intraepithelial lesions, we recommend that all women with atypical or low-grade cytology be recalled for colposcopy and high-risk human papillomavirus deoxyribonucleic acid testing, if available. Decisions whether to perform a biopsy should be based on the result of colposcopic examination. Performing colposcopy only on those patients who have cytologic high-grade squamous intraepithelial lesions and following those with lower grade cytologic anomalies without colposcopic diagnosis appears inadequate to rule out high-grade cervical intraepithelial neoplasia. 相似文献

HPV testing in cervical screening 总被引:1,自引:0,他引:1

High-risk human papillomavirus (hrHPV) bearing cervical intraepithelial neoplasia (CIN) is considered, as the real precursor lesion of cervical cancer and persistence of an hrHPV infection is necessary for the progression to cervical cancer. This knowledge warrants the use of hrHPV testing as an adjunct to cervical cytology in population-based screening programmes and for monitoring therapy efficacy of high-grade CIN lesions. Replacement of cytology by hrHPV testing altogether is considered, but for this to be (cost-) effective, accurate information about the specificity of the hrHPV test is required. Additional test systems that can be used to stratify women with a positive hrHPV test are HPV genotyping, viral load analysis and hrHPV mRNA analysis. The need for HPV genotyping of cervical smears is illustrated by the increased risk for high-grade cervical lesions associated with HPV types 16 and 18. In particular, for women who have normal but persistently (>1 year) HPV18-positive smears, endocervical curettage is suggested (evidently considering the age and possible future pregnancies of the respective woman) because HPV18 is associated with glandular lesions in the cervix, which are difficult to detect by cytology. 相似文献

OBJECTIVE: We evaluated high-risk human papillomavirus (HPV) testing by Hybrid Capture II (HC II) in addition to cytology to predict recurrent/residual cervical intraepithelial neoplasia (CIN) 2/3 and cervical cancer in women treated for CIN 3. METHODS: Follow-up study of 108 women with histologically confirmed CIN 3. RESULTS: Pretreatment, in 96% (104/108) of the smears high-risk HPV DNA was present. Posttreatment, 71% (77/108) of the women had normal cytology and negative HC II test and none developed recurrent/residual disease during a median follow-up of 28.8 months with a range of 2.4-64.8 months. One of the 12% (13/108) of women with normal cytology and positive HC II test was diagnosed with cervical adenocarcinoma. One of the 7% (8/108) of women with abnormal cytology (borderline dyskaryosis or worse) and negative HC II test was diagnosed with CIN 2. Three of the 9% (10/108) of women with abnormal cytology and a positive HC II test were diagnosed with CIN 2/3. These results show an increased risk for recurrent/residual CIN 2/3 and cervical carcinoma when at least one posttreatment test is positive. The highest relative risk (72.9, 95% CI 25-210) was present in women with both tests positive. CONCLUSIONS: HPV testing with Hybrid Capture II in conjunction with cytology can be used as a tool to select women with an increased risk for recurrent/residual CIN 2/3 and cervical cancer. The standard policy in The Netherlands is cytology at 6, 12, and 24 months posttreatment. However, for women with both normal cytology and negative HC II test at 6 months the chance to develop recurrent/residual CIN 2/3 and cervical carcinoma is so low that retesting at 12 months can be omitted. 相似文献

OBJECTIVE: The goal of this study was to investigate whether expanded cytologic referral criteria for colposcopy or the addition of human papillomavirus (HPV) testing on cervical screening could improve the rates of detection of cervical intraepithelial neoplasia (CIN). METHODS: HPV testing by semiquantitative polymerase chain reaction/ELISA was performed in 1000 women who were self-referred for routine Pap smear. They underwent colposcopy following an abnormal smear result or a positive HPV test. As abnormal smear results were considered reports of low- or high-grade squamous intraepithelial lesion, atypical squamous cells of undetermined significance, and even HPV-associated reactive cellular changes (mild koilocytosis, mild dyskeratocytosis, hyperchromatic nuclei, bimultinucleation, and cleared cytoplasm). Loop excision of the transformation zone was performed in women with cytology and colposcopy indicative of CIN, as well as in women with normal cytology but positive HPV test and colposcopic impression of CIN. RESULTS: The Pap test was abnormal in 89% of the cases of CIN 1 (34/38) and 96% of CIN 2/3 (27/28) diagnosed in our population. HPV testing picked up four additional cases of CIN 1 (11%) and one case of CIN 2/3 (4%). Overall the HPV test detected 95% of the cases of CIN 1 (36/38) and 89% of the cases of CIN 2/3 (25/28). CONCLUSION: HPV testing does not appear to add significantly to cytology in terms of positive predictive value or detection rate, if extended cytologic indications for colposcopy are used. 相似文献

The current status of HPV DNA testing 总被引:5,自引:0,他引:5

Infection with high-risk types of HPV underlies most cases of high-grade cervical intraepithelial neoplasia (CIN) and practically all cases of invasive cervical cancer. Currently, cervical HPV DNA is detected by means of PCR and sandwich capture molecular hybridization methods. Research has focused on the potential role of HPV testing in three conditions: screening for cervical neoplasia, triage of women with low-grade lesions and follow-up after conservative surgical treatment for CIN. Concerning the first condition, HPV testing does not seem to offer an obvious advantage over traditional cytology screening, mainly due to false positive results in younger women with transient HPV infection. A possible exemption to this is the case of middle-aged women and low-resource settings, where the excellent sensitivity of a HPV test is desirable. Although data are controversial regarding low grade lesions, results from randomized studies indicate that HPV testing could be useful in a triage of women with an initial cytological diagnosis of ASCUS, where detection of DNA of a high-risk type should lead to colposcopy. Although there is a lack of randomized controlled trials in this field, data from observational studies indicate that HPV DNA testing after conservative surgical treatment for CIN may be very sensitive and detect early residual and recurrent disease. 相似文献

Setting Three UK centres: Manchester, Aberdeen and London.
Population or sample Women treated for cervical intraepithelial neoplasia (CIN).
Methods Women were recruited at 6 months of follow up, and cytology and HPV testing was carried out at 6 and 12 months. If either or both results were positive, colposcopy and if appropriate, a biopsy and retreatment was performed. At 24 months, cytology alone was performed.
Main outcome measures Cytology and histology at 6, 12 and 24 months.
Results Nine hundred and seventeen women were recruited at 6 months of follow up, with 778 (85%) and 707 (77.1%) being recruited at 12 and 24 months, respectively. At recruitment, 700 women had had high-grade CIN (grades 2 or 3) and 217 had CIN1. At 6 months, 14.6% were HPV positive and 10.7% had non-negative cytology. Of those with negative cytology, 9% were HPV positive. Of the 744 women who were cytology negative/HPV negative at baseline, 3 women with CIN2, 1 with CIN3, 1 with cancer and 1 with vaginal intraepithelial neoplasia (VAIN)1 were identified at 24 months. Nine of 10 cases of CIN3/cervical glandular intraepithelial neoplasia (CGIN) occurred in HPV-positive women. At 23 months, cancer was identified in a woman treated for CGIN with clear resection margins, who had been cytology negative/HPV negative at both 6 and 12 months.
Conclusions Women who are cytology negative and HPV negative at 6 months after treatment for CIN can safely be returned to 3-year recall. 相似文献

This systematic review examined the risk of cervical dysplasia among women who have undergone a colposcopy episode of care to inform their return to population-based cervical screening. PubMed, Embase, and grey literature were searched between January 2000 and 2018. One reviewer screened citations against pre-defined eligibility criteria. A second reviewer verified 10% and 100% of exclusions at title and abstract and at full-text screening, respectively. One reviewer extracted data and assessed methodological quality of included articles; a second reviewer verified these in full. The primary outcome was incidence of cervical intraepithelial neoplasia grade 2 or greater (CIN2+) subsequent to initial colposcopy evaluation. Secondary outcomes included incidence of CIN2+ after negative follow-up test results and performance of follow-up strategies. Results were synthesized narratively. A total of 48 studies were included. The 1- to 5-year CIN2+ risks after colposcopy evaluation ranged from 2.4% to 16.5% among women treated for CIN2+ and from 0.7% to 16.8% among women untreated for CIN grade 1 or less (≤CIN1). Follow-up strategies included single or repeat cytology, human papillomavirus (HPV) testing, or combined HPV/cytology co-testing at various intervals. After negative follow-up test results, risk varied by follow-up strategy for both groups and by referral cytology severity for untreated women. Performance of follow-up strategies varied among treated women. Among untreated women, co-testing demonstrated greater sensitivity than cytology alone. In conclusion, women treated during colposcopy for CIN2+ and women with ≤CIN1 who were referred to colposcopy for low-grade cytology and who did not receive treatment may be able to return to population-based screening after negative co-testing results. Current evidence does not suggest that women untreated for ≤CIN1 who are referred for high-grade cytology be returned to screening at an average risk interval. The optimal strategy for colposcopy discharge needs ongoing evaluation as implementation of HPV testing evolves. 相似文献

OBJECTIVE: To assess the usefulness of human papilloma virus (HPV) typing for predicting pre-malignant and malignant cervical lesions. STUDY DESIGN: 314 women, who underwent colposcopy, biopsies and high and low-risk HPV typing after a confirmed abnormal routine Pap test were studied. HPV-DNAs were typed by using PCR technique. RESULTS: We found a significant increasing rate of high-risk-HPV by the increasing severity of histology, ranging from 40% in negative cases to 86.9% in those with CIN3 lesions. The positive predictive value of high-risk-HPV ranged from 13.3% in patients with atypical squamous cells of undetermined significance (ASCUS) to 29.4% in those with HSIL. By contrast, negative predictive value was 96% in patients with ASCUS, 97.2% in low-grade squamous intraepithelial lesions (LSIL), and 71.4% in high-grade squamous intraepithelial lesions (HSIL). Sensitivity and specificity for detecting CIN2 or CIN3 was 86.0% and 41.3%, respectively. CONCLUSIONS: The high negative predictive value of high-risk HPV testing suggests that HPV negativity could be used for predicting the absence of important cervical lesions, and therefore avoiding unnecessary colposcopy in ASCUS and LSIL cases. 相似文献
