Population prevalence of human papillomavirus (HPV) and cervical intraepithelial neoplasias (CIN) is an important indicator to judge the disease burden in the community, to monitor the performance of cervical cancer screening program and to assess the impact of HPV vaccination program. India being a country without any cervical cancer screening program has no published data on the population prevalence of CIN and only a few large community‐based studies to report the high‐risk HPV prevalence. The objective of our study was to study HPV and CIN prevalence in a previously unscreened population. We pooled together the results of three research studies originally designed to assess the performance of visual inspection after acetic acid application and Hybrid Capture 2 (HC 2). Nearly 60% of the screened women had colposcopy irrespective of their screening test results. The diagnosis and grading of cervical neoplasias were based on histology. The age standardized prevalence of HPV by HC 2 test was 6.0%. Age‐adjusted prevalence of CIN1 and CIN2 was 2.3% and 0.5%, respectively. The age‐adjusted prevalence of CIN3 was 0.4% and that of invasive cancer was 0.2%. The prevalence of high‐risk HPV was relatively low in the population we studied, which is reflected in the low prevalence of high‐grade CIN. The prevalence of CIN3 remained constant across age groups due to absence of screening. 相似文献

To test the reliability of the Hybrid Capture II (HC-II) assay detecting 13 high-risk human papillomavirus (HR-HPV) types for the screening of cervical lesions, we monitored by cytology, HR-HPV testing, colposcopy and biopsy, 3,091 women with normal smears at the first entry. Our primary endpoint was clinical progression defined as the presence of a high-grade lesion (HGSIL) at the biopsy. In our population of 659 HR-HPV-infected women, 241 (36.6%) had a positive HR-HPV test at 2 to 4 examinations with a final histological diagnosis of HGSIL in 51 cases (21.2%) within 4 to 36 months, while women with regressive HPV infection did not develop any lesion during the same period. In the cohort of 2,432 women testing negative for HR-HPV infection, only 2 women (0.08%) developed a HGSIL. Both were HR-HPV positive 18 and 24 months after the first entry, at the time of diagnosis of disease. The RR of incident HGSIL when a HR-HPV was detected at enrollment in women with normal smears was 96.7 (95% CI, 95.8-97.7). The RR increased to 237.3 (95% CI, 222.8-251.8) when the HR-HPV test remained positive at 2 controls, and to 314.3 (95% CI, 260.7-367.9) when the HR-HPV test was positive at 3 controls. The evaluation of the viral load of HR-HPV by the HC-II did not represent a sensitive approach to predict the recurrence of HR-HPV infection and/or the apparition of HGSIL. Nevertheless, a recurrent HR-HPV infection detected with HC-II represents a reliable tool to select populations at risk for the development of HGSIL. 相似文献

In this prospective cohort study, we estimated the long‐term risk of cervical intraepithelial neoplasia grade 3 or cancer (CIN3+) by high‐risk human papillomavirus (hrHPV) genotype and semi‐quantitative viral load at baseline among 33,288 women aged 14–90 years with normal baseline cytology. During 2002–2005, residual liquid‐based cervical cytology samples were collected from women screened for cervical cancer in Copenhagen, Denmark. Samples were HPV‐tested with Hybrid Capture 2 (HC2) and genotyped with INNO‐LiPA. Semi‐quantitative viral load was measured by HC2 relative light units in women with single hrHPV infections. The cohort was followed in a nationwide pathology register for up to 11.5 years. In women aged ≥30 years at baseline, the 8‐year absolute risk for CIN3+ following baseline detection of HPV16 was 21.8% (95% confidence interval [CI]: 18.0–25.6%). The corresponding risks for HPV18, HPV31, HPV33, and other hrHPV types, respectively, were 12.8% (95% CI: 7.6–18.0%), 11.3% (95% CI: 7.7–14.9%), 12.9% (95% CI: 7.0–18.8%) and 3.9% (95% CI: 2.7–5.2%). Similar absolute risk estimates were observed in women aged <30 years. Higher HPV16‐viral load was associated with increased risk of CIN3+ (hazard ratio = 1.34, 95% CI: 1.10–1.64, per 10‐fold increase in viral load). A similar trend, although statistically nonsignificant, was found for viral load of HPV18. The 8‐year absolute risk of CIN3+ in women with HPV16‐viral load ≥100.0 pg/ml was 30.2% (95% CI: 21.9–38.6%). Our results support that hrHPV genotyping during cervical cancer screening may help identify women at highest risk of CIN3+. 相似文献

Long‐term follow‐up of the risk for cervical intraepithelial neoplasia grade 2 or worse in HPV‐negative women after conization 下载免费PDF全文

Little research has been conducted on the long‐term value of human papillomavirus (HPV) testing after conization. We investigated whether cytology adds to the value of a negative HPV test for long‐term prediction of cervical intraepithelial neoplasia grade 2 or worse (CIN2+). In addition, we compared risk of CIN2+ following a negative HPV test in women after conization with that in women from the general population. During 2002–2005, 667 women treated for CIN2+ were tested for HPV and cytology 46 months after conization. Only HPV‐negative women were included. Women participating in routine screening were age‐matched with post‐conization HPV‐negative women, leaving 13,230 and 477 women, respectively, for analysis. By linkage to the Pathology Data Bank, we identified all cases of CIN2+ by December 2013. The 3‐, 5‐, 8‐ and 10‐year risks for CIN2+ were 0.7, 0.9, 2.8 and 5.7% after a negative HPV test and 0.5, 0.8, 2.9 and 6.1% in HPV and cytology‐negative women. HPV‐negative women in the general population had similar 3‐year and 5‐year risks of 0.4 and 1.0%; thereafter, they had lower risks of 1.9% at 8 years and 2.7% at 10 years. Our results indicate that HPV testing may be used as a test of cure after conization. In the first 5 years after testing, the risk for CIN2+ of women who were HPV‐negative at 34 months after conization was similar to that of HPV‐negative women in the general population. After 67 years, however, women who have undergone conization may be at higher risk for CIN2+. 相似文献

Stratifying HPV‐positive women for CIN3+ risk after one and two rounds of HPV‐based screening 下载免费PDF全文
Nienke J. Veldhuijzen Nicole J. Polman Peter J.F. Snijders Chris J.L.M. Meijer Johannes Berkhof 《International journal of cancer. Journal international du cancer》2017,141(8):1551-1560
A main challenge of human papilloma (HPV)‐based screening for cervical cancer is to adequately identify HPV‐positive women at highest risk of cervical intraepithelial neoplasia grade 3 or worse, CIN3+. The prognostic value of currently used adjunct markers (HPV16/18 genotyping and reflex cytology) may change after multiple rounds of HPV‐based screening because of a change in the proportion of HPV‐positive women with incident infections. To this end, we re‐analyzed results from the POBASCAM trial (Population Based Screening Study Amsterdam). Women were randomized to HPV/cytology cotesting (intervention group) or to cytology‐only (HPV blinded; control group) at enrolment. Our analytical population consisted of women with an HPV‐positive result at the second round, 5 years after enrolment (n = 381 intervention, n = 392 control). Nine‐year CIN3+ risks were estimated by Kaplan–Meier. HPV‐positive women were stratified by risk markers: HPV16/18 genotyping, reflex cytology and preceding HPV results. When comparing one to two rounds of HPV‐based screening, the prognostic value of an abnormal cytology result did not change (40.0% vs. 42.3%, p = 0.5617), but diminished for an HPV16/18 positive result (25.4% vs. 38.0%, p = 0.0132). HPV16/18 genotyping was nondiscriminative in women with incident HPV infections (HPV16/18 positive 10.0% vs. negative 12.1%, p = 0.3193). Women from the intervention group were more likely to have incident infections compared to women from the control group (incident screen‐positive results 75.6% vs. 64.6%, p = 0.001) Our results indicate that at a second round of HPV‐based screening, risk differentiation by cytology remained strong, but was diminished for HPV 16/18 genotyping because of a larger proportion of incident infections. 相似文献

The clinical value of HPV genotyping in triage of women with high‐risk‐HPV‐positive self‐samples 下载免费PDF全文

Cytology alone, or combined with HPV16/18 genotyping, might be an acceptable method for triage in hrHPV‐cervical cancer screening. Previously studied HPV‐genotype based triage algorithms are based on cytology performed without knowledge of hrHPV status. The aim of this study was to explore the value of hrHPV genotyping combined with cytology as triage tool for hrHPV‐positive women. 520 hrHPV‐positive women were included from a randomised controlled self‐sampling trial on screening non‐attendees (PROHTECT‐3B). Eighteen baseline triage strategies were evaluated for cytology and hrHPV genotyping (Roche Cobas 4800) on physician‐sampled triage material. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), referral rate, and number of referrals needed to diagnose (NRND) were calculated for CIN2+ and CIN3+. A triage strategy was considered acceptable if the NPV for CIN3+ was ≥98%, combined with maintenance or improvement of sensitivity and an increase in specificity in reference to the comparator, being cytology with a threshold of atypical cells of undetermined significance (ASC‐US). Three triage strategies met the criteria: HPV16+ and/or ≥LSIL; HPV16+ and/or ≥HSIL; (HPV16+ and/or HPV18+) and/or ≥HSIL. Combining HPV16+ and/or ≥HSIL yielded the highest specificity (74.9%, 95% CI 70.5–78.9), with a sensitivity (94.4%, 95% CI 89.0–97.7) similar to the comparator (93.5%, 95% CI 87.7–97.1), and a decrease in referral rate from 52.2% to 39.5%. In case of prior knowledge of hrHPV presence, triage by cytology testing can be improved by adjusting its threshold, and combining it with HPV16/18 genotyping. These strategies improve the referral rate and specificity for detecting CIN3+ lesions, while maintaining adequate sensitivity. 相似文献

Using nationwide Danish registries we examined the long‐term risk of cervical cancer in women diagnosed with cervical intraepithelial neoplasia grade 3 (CIN3) (including adenocarcinoma in situ (AIS)) on the cone compared to women with a normal cytology test. Initially, we identified women born 1918–1990, who were recorded as living in Denmark between January 1, 1978 and December 31, 2012. From the Pathology Data Bank information on CIN3 on the cone, margins status, histological type of CIN3 and cervical cytology results was extracted. Cox proportional hazard model was used to estimate the relative risk of subsequent cervical cancer. We included 59,464 women with CIN3 on the cone and 1,918,508 women with a normal cytology test. Overall, women diagnosed with CIN3 had a higher risk of subsequent cervical cancer compared to women with normal cytology (HR = 2.06; 95%CI: 1.81–2.35). Analyses according to time since conization showed elevated risks in all time periods, and 25 years or more after conization the relative risk was significantly increased (HR = 2.56; 95%CI: 1.37–4.77). Twenty years or more after conization, also women with negative margins had an increased relative risk (HR = 2.49; 95%CI: 1.12–5.57). In addition, the long‐term relative risk of cervical cancer varied with the different histological types of CIN3 and was highest for AIS (HR = 7.50; 95%CI: 1.87–30.01, 10–14 years after conization). In conclusion, women diagnosed with CIN3 on the cone have a long‐lasting increased risk of cervical cancer even when the margins on the cone are negative. 相似文献

Women treated for high‐grade cervical intraepithelial neoplasia (CIN) are at risk of recurrent CIN Grade 2 or worse (rCIN2+). Currently, posttreatment monitoring is performed using cytology or cytology/high‐risk (hr)HPV cotesting. This study aimed to evaluate the performance of p16/Ki‐67 dual‐stained cytology (p16/Ki‐67) for posttreatment monitoring. Three hundred and twenty‐three women treated for high‐grade CIN in the SIMONATH study underwent close surveillance by cytology, hrHPV and DNA methylation marker testing up to 12 months posttreatment. Histological endpoints were ascertained by colposcopy with biopsy at 6 and/or 12 months. p16/Ki‐67 dual‐staining was performed on residual liquid‐based cytology samples obtained at, or shortly before biopsy collection. Clinical performance estimates of cytology, hrHPV, p16/Ki‐67 testing and combinations thereof for the detection of rCIN2+ were determined and compared to each other. Sensitivity of p16/Ki‐67 for rCIN2+ (69.2%) was nonsignificantly lower than that of cytology (82.1%; ratio 0.84, 95% CI: 0.71–1.01), but significantly lower than that of hrHPV testing (84.6%; ratio 0.82, 95% CI: 0.68–0.99). Specificity of p16/Ki‐67 for rCIN2+ (90.4%) was significantly higher compared to both cytology (70.8%; ratio 1.28, 95% CI: 1.19–1.37) and hrHPV testing (76.2%; ratio 1.19, 95% CI: 1.12–1.26). Overall, hrHPV testing showed very high sensitivity, along with a good specificity. When considering cotesting, combined p16/Ki‐67/hrHPV testing showed rCIN2+ sensitivity comparable to cytology/hrHPV cotesting (87.2% vs. 89.7%; ratio 0.97, 95% CI: 0.92–1.03), but with significantly increased specificity (74.2% vs. 58.1%; ratio 1.28, 95% CI: 1.19–1.38). Thus, when considered in combination with hrHPV, p16/Ki‐67 might be an attractive approach for surveillance of women treated for high‐grade CIN. 相似文献

Studies of the clinical relevance of human papillomavirus (HPV) DNA load have focused mainly on HPV16 and HPV18. Data on other oncogenic types are rare. Study subjects were women enrolled in the atypical squamous cells of undetermined significance (ASC‐US) and low‐grade squamous intraepithelial lesion (LSIL) triage study who had ≥1 of 11 non‐HPV16/18 oncogenic types detected during a 2‐year follow‐up at 6‐month intervals. Viral load measurements were performed on the first type‐specific HPV‐positive specimens. The association of cervical intraepithelial neoplasia grades 2–3 (CIN2/3) with type‐specific HPV DNA load was assessed with discrete‐time Cox regression. Overall, the increase in the cumulative risk of CIN2/3 per 1 unit increase in log10‐transformed viral load was statistically significant for four types within species 9 including HPV31 (adjusted hazard ratio [HR adjusted] = 1.32: 95% confidence interval [CI], 1.14–1.52), HPV35 (HR adjusted = 1.47; 95% CI, 1.23–1.76), HPV52 (HR adjusted = 1.14; 95% CI, 1.01–1.30) and HPV58 (HR adjusted = 1.49; 95% CI, 1.23–1.82). The association was marginally significant for HPV33 (species 9) and HPV45 (species 7) and was not appreciable for other types. The per 1 log10‐unit increase in viral load of a group of species 9 non‐HPV16 oncogenic types was statistically significantly associated with risk of CIN2/3 for women with a cytologic diagnosis of within normal limits, ASC‐US, or LSIL at the first HPV‐positive visit but not for those with high‐grade SIL. Findings suggest that the viral load‐associated risk of CIN2/3 is type‐dependent, and mainly restricted to the species of HPV types related to HPV16, which shares this association. 相似文献

Recently, DNA methylation analysis of FAM19A4 in cervical scrapes has been shown to adequately detect high‐grade cervical intraepithelial neoplasia and cervical cancer (≥CIN3) in high‐risk HPV (hrHPV)‐positive women. Here, we compared the clinical performance of FAM19A4 methylation analysis to cytology and HPV16/18 genotyping, separately and in combination, for ≥CIN3 detection in hrHPV‐positive women participating in a prospective observational multi‐center cohort study. The study population comprised hrHPV‐positive women aged 18–66 years, visiting a gynecological outpatient clinic. From these women, cervical scrapes and colposcopy‐directed biopsies (for histological confirmation) were obtained. Cervical scrapes were analyzed for FAM19A4 gene promoter methylation, cytology and HPV16/18 genotyping. Methylation analysis was performed by quantitative methylation‐specific PCR (qMSP). Sensitivities and specificities for ≥CIN3 were compared between tests. Stratified analyses were performed for variables that potentially influence marker performance. Of all 508 hrHPV‐positive women, the sensitivities for ≥CIN3 of cytology, FAM19A4 methylation analysis, and cytology combined with HPV16/18 genotyping were 85.6, 75.6 and 92.2%, respectively, with corresponding specificities of 49.8, 71.1 and 29.4%, respectively. Both sensitivity and specificity of FAM19A4 methylation analysis were associated with age (p ≤ 0.001 each). In women ≥30 years (n = 287), ≥CIN3 sensitivity of FAM19A4 methylation analysis was 88.3% (95%CI: 80.2–96.5) which was noninferior to that of cytology [85.5% (95%CI: 76.0–94.0)], at a significantly higher specificity [62.1% (95%CI: 55.8–68.4) compared to 47.6% (95%CI: 41.1–54.1)]. In conclusion, among hrHPV‐positive women from an outpatient population aged ≥30 years, methylation analysis of FAM19A4 is an attractive marker for the identification of women with ≥CIN3. 相似文献

The Japanese government began a human papillomavirus (HPV) vaccination program for girls aged 12‐16 years in 2010 but withdrew its recommendation in 2013 because of potential adverse effects, leading to drastically reduced vaccination uptake. To evaluate population‐level effects of HPV vaccination, women younger than 40 years of age newly diagnosed with cervical intraepithelial neoplasia grade 1‐3 (CIN1‐3), adenocarcinoma in situ (AIS), or invasive cervical cancer (ICC) have been registered at 21 participating institutes each year since 2012. A total of 7709 women were registered during 2012‐2017, of which 5045 were HPV genotyped. Declining trends in prevalence of vaccine types HPV16 and HPV18 during a 6‐year period were observed in CIN1 (50.0% to 0.0%, Ptrend < .0001) and CIN2‐3/AIS (83.3% to 45.0%, Ptrend = .07) only among women younger than 25 years of age. Overall, HPV vaccination reduced the proportion of HPV16/18‐attributable CIN2‐3/AIS from 47.7% to 33.0% (P = .003): from 43.5% to 12.5% as routine vaccination (P = .08) and from 47.8% to 36.7% as catch‐up vaccination (P = .04). The HPV16/18 prevalence in CIN2‐3/AIS cases was significantly reduced among female individuals who received their first vaccination at age 20 years or younger (P = .02). We could not evaluate vaccination effects on ICC owing to low incidence of ICC among women aged less than 25 years. We found HPV vaccination to be effective in protecting against HPV16/18‐positive CIN/AIS in Japan; however, our data did not support catch‐up vaccination for women older than 20 years. Older adolescents who skipped routine vaccination due to the government’s suspension of its vaccine recommendation could benefit from receiving catch‐up vaccination before age 20 years. 相似文献

Little is known about acquisition of human papillomavirus (HPV) and its outcome among older women with negative HPV testing and normal cytology. A longitudinal 3‐yr follow‐up of nested‐cohort subjects (n = 8825) from a population‐based cervical cancer screening study whose Pap and HPV tests were negative at baseline were conducted. Every active HPV‐negative (n = 413) participant had 12‐mo follow‐ups of Pap smear and HPV testing. Colposcopy was performed if either HPV‐positive or cytology was abnormal. The cytology and histology information of the remaining subjects (passive HPV‐negative, n = 8412) was obtained from national registry database. Median age of participants was 45 yr (range, 30–73 yr). The incidence of new acquisition was 4.2/100 woman‐years. The 3‐yr cumulative total HPV acquisition rate was 11.1% (95% confidence interval [CI]: 8.1–14.1). Increased number of sexual partners (≥2 vs. 1) of the participant was associated with risk of acquisition (odds ratio [OR]: 5.0, 95% CI: 2.0–12.6) by multivariate analysis. Three cases of ≥ cervical intraepithelial neoplasia (CIN) 2 were identified in 3‐yr follow‐up in active HPV‐negative subjects. HPV genotypes in the dysplastic tissue were actually present at baseline samples after reanalysis. From the passive HPV‐negative group, only 1 case progressed to CIN2 probably after HPV acquisition. Negative Pap and HPV tests assured a very low risk of developing ≥ CIN2 within 3 yr despite incident HPV infection. 相似文献

Human papillomavirus (HPV) types 16/18, included in HPV vaccines, contribute to the majority of cervical cancer, and a substantial proportion of cervical intraepithelial neoplasia (CIN) grades 2/3 or worse (CIN2+/CIN3+) including adenocarcinoma in situ or worse. The aim of this study was to quantify the effect of quadrivalent HPV (qHPV) vaccination on incidence of CIN2+ and CIN3+. A nationwide cohort of girls and young women resident in Sweden 2006–2013 and aged 13–29 (n = 1,333,691) was followed for vaccination and histologically confirmed high‐grade cervical lesions. Data were collected using the Swedish nationwide healthcare registers. Poisson regression was used to calculate incidence rate ratios (IRRs) and vaccine effectiveness [(1‐IRR)x100%] comparing fully vaccinated with unvaccinated individuals. IRRs were adjusted for attained age and parental education, and stratified on vaccination initiation age. Effectiveness against CIN2+ was 75% (IRR = 0.25, 95%CI = 0.18–0.35) for those initiating vaccination before age 17, and 46% (IRR = 0.54, 95%CI = 0.46–0.64) and 22% (IRR = 0.78, 95%CI = 0.65–0.93) for those initiating vaccination at ages 17–19, and at ages 20–29, respectively. Vaccine effectiveness against CIN3+ was similar to vaccine effectiveness against CIN2+. Results were robust for both women participating to the organized screening program and for women at prescreening ages. We show high effectiveness of qHPV vaccination on CIN2+ and CIN3+ lesions, with greater effectiveness observed in girls younger at vaccination initiation. Continued monitoring of impact of HPV vaccination in the population is needed in order to evaluate both long‐term vaccine effectiveness and to evaluate whether the vaccination program achieves anticipated effects in prevention of invasive cervical cancer. 相似文献

We determined whether the participation rate for a brush‐based cervicovaginal self‐sampling device is noninferior to the participation rate for a lavage‐based one for testing for hrHPV (high‐risk human papillomavirus). Additionally, positivity rates for hrHPV, the detection rates for cervical intraepithelial neoplasia grades 2 and 3 or worse (CIN2+/3+), and user comfort were compared. A total of 35,477 non‐responders of the regular cervical screening program aged 33–63 years were invited to participate. Eligible women (n = 30,130) were randomly assigned to receive either a brush‐based or a lavage‐based device, and a questionnaire for reporting user convenience. Self‐sampling responders testing hrHPV‐positive were invited for a physician‐taken sample for cytology; triage‐positive women were referred for colposcopy. A total of 5,218 women participated in the brush‐based sampling group (34.6%) and 4809 women in the lavage‐based group (31.9%), i.e. an absolute difference of 2.7% (95%CI 1.8–4.2). The hrHPV‐positivity rates in the two groups were identical (8.3%, relative risk (RR) 0.99, 95%CI 0.87–1.13). The detection of CIN2+ and CIN3+ in the brush group (2.0% for CIN2+; 1.3% for CIN3+) was similar to that in the lavage group (1.9% for CIN2+; 1.0% for CIN3+) with a cumulative RR of 1.01, 95%CI 0.83–1.24 for CIN2+ and 1.25, 95%CI 0.92–1.70 for CIN3+. The two self‐sampling devices performed similarly in user comfort. In conclusion, offering a brush‐based device to non‐responders is noninferior to offering a lavage‐based device in terms of participation. The two self‐sampling methods are equally effective in detecting hrHPV, CIN2+/CIN3+ and are both well accepted. 相似文献

Oncogenic HPV types are the major cause of worldwide cervical cancer, but only a small proportion of infected women will develop high-grade cervical intraepithelial neoplasia or cancer (CIN2/3+). We performed a prospective study including 781 women with normal, atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LGSIL) cytology, and infected or not by high-risk (HR) HPV tested by Hybrid Capture II. Women were followed up every 6 months for a median period of 22 months. Among the HR-HPV-positive women at entry, more than half cleared their virus in 7.5 months; the clearance rate was greater for low viral loads than for high loads and also was higher in women with an initial ASCUS/LGSIL smear than in women with normal cytology. The incidence of cytologic abnormalities strongly depended on baseline viral load and HR-HPV persistence. Maintenance of cytologic abnormalities was associated with the outcome of HR-HPV status (negative or =100 pg/mL). Conversely, women who were consistently HR-HPV negative or transiently HR-HPV positive, whatever the cytology at baseline was, did not develop CIN2/3+ during follow-up. Age seemed to affect only the rate of incident HR-HPV infection. In conclusion, our data suggest that women repeatedly tested positive for HR-HPV are at risk of developing CIN2/3+, even when initial cytology is normal. A high viral load could be used as a short-term marker of progression toward precancerous lesions, although lower load does not inevitably exclude progressive disease. 相似文献

We studied the effectiveness of high‐risk human papillomavirus (hrHPV) triage for immediate colposcopy in women with borderline or mild dyskaryosis (BMD). In the Utrecht province of the Netherlands, women aged 30–60 years who participated in the regular cervical screening programme were offered hrHPV testing and cytology (intervention group) or cytology only (control group). In the intervention group (n = 337), women with BMD were immediately referred for colposcopy only if the sample was hrHPV positive. Women with a hrHPV negative test were advised to repeat cytology at 6 and 18 months and were referred for colposcopy if and when the repeat test result was positive (BMD or worse). In the control group (n = 329), referral of women with BMD was delayed until cytology was repeatedly positive at 6 or 18 months. The CIN3 detection rates were 10.7% (36/337) in the intervention group and 6.4% (21/329) in the control group (p = 0.047). Moreover, hrHPV triaging resulted in shorter time to diagnosis (154 vs. 381 days). Although the number of colposcopy referrals was 51.5% higher in the intervention group than in the control group, the medical costs per detected CIN3 were slightly lower ([euro] 4781 vs. [euro] 6235). If, in addition, hrHPV negative women had been referred back to routine screening at baseline, the CIN3 rate would have been 10.1% (34/337) and colposcopy rate would only have been 30.4% higher than in the control group. This study shows that hrHPV triaging of women with BMD is at least as effective for detecting CIN3 as repeat cytology, also when hrHPV negative women are referred back to routine screening. 相似文献
