Colposcopy services in the United Arab Emirates.

BACKGROUND: United Arab Emirates (UAE) is a young country with a population of 3 million, an abundant oil wealth, and a high standard of living. There is no organized cervical screening program, but the authorities are planning to introduce one soon. OBJECTIVE: To study the availability and quality of colposcopy services. METHODS: A questionnaire survey of all gynecologists in the major government and private hospitals in the country. RESULTS: Twenty government hospitals offer obstetrics and gynecology services, 11 governments and 4 private hospitals have colposcopy services. Of the 52 specialists performing colposcopy, 8 had adequate training, 3 had formal recognition, and 3 had long-term experience. The number of cases seen per doctor varies from 10 to 100 a year, with a mean and median of 28 and 15, respectively. Three units had the required basic colposcopy equipment for diagnosis and treatment. Only 1 unit performs audit. CONCLUSIONS: Colposcopy service is widely available in many hospitals in the United Arab Emirates, but substantial variation exists in clinical standards and needs more organization and standardization.

Outcome after negative colposcopy among human immunodeficiency virus-infected women with borderline cytologic abnormalities.

OBJECTIVE: To estimate the risk of and risk factors for progression among human immunodeficiency virus (HIV)-seropositive women with abnormal cervical cytology but negative colposcopy. METHODS: In a prospective cohort study, 391 HIV-seropositive and 103 seronegative women with cervical cytology read as atypical squamous cells (ASC) or low-grade squamous intraepithelial lesion (LSIL) but negative colposcopy were followed up for a mean of 4.0 years with cytology at 6-month intervals. Colposcopy was prescribed for any epithelial abnormality. RESULTS: Progression to CIN2, CIN3, high-grade SIL/severe dysplasia, or cancer occurred in 47 (12%) HIV-seropositive women and 4 (4%) HIV-seronegative women (P = .02). Progression to CIN1 was seen in an additional 12 HIV-seropositive women and 1 seronegative woman. In multivariate analysis, high-risk but not low-risk HPV detection (hazard ratio [HR] 2.46-95% confidence interval [CI] 1.18-5.12, P = .02 for high risk, HR 1.41, 95% CI 0.62-3.21, P = .42 for low risk), satisfactory colposcopy (HR 2.01, 95% CI 1.11-3.65, P = .02), and non-Hispanic African-American ethnicity (HR 5.08, 95% CI 1.72-14.98, P = .003) were the only factors associated with progression, while HIV serostatus was marginally significant (HR 2.53, 95% CI 0.85-7.50, P = .09). CONCLUSION: Human immunodeficiency virus-seropositive women with negative colposcopy after borderline cytology face a higher risk of progression than seronegative women, but the absolute risk is low and becomes nonsignificant after controlling for HPV risk type, ethnicity, and colposcopic findings. Observation is appropriate. LEVEL OF EVIDENCE: II-2.

Colposcopy in the management of the pregnant patient with abnormal cervical cytology.

Thirty patients with abnormal cervical cytology had a colposcopy during pregnancy. Their management during and after pregnancy is described and supports the contention that the introduction of a colposcopy service safely permits a greater selectivity in management without recourse to operative intervention during pregnancy. In one patient a preclinical invasive squamous carcinoma of the cervix was diagnosed by colposcopy, and in another three, in whom colposcopy could not exclude the presence of invasion, a wedge biopsy under anaesthesia and two punch biopsies without anaesthesia had to be performed. In the remaining 26 patients, the possibility of invasion could be excluded by colposcopy and further treatment deferred until after pregnancy.

Human papillomavirus testing improves the accuracy of colposcopy in detection of cervical intraepithelial neoplasia.

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.

Women's experiences in coping with abnormal Papanicolaou results and follow-up colposcopy.

OBJECTIVES: To delineate the primary concerns women associate with abnormal Papanicolaou (Pap) results and colposcopy and to identify women's strategies for coping with these potential stressors. DESIGN: A longitudinal, descriptive study involving telephone interviews after participants received abnormal Pap results and mailed questionnaires before and after colposcopy. SETTING: Private and public women's health clinics in the midwestern United States. PARTICIPANTS: Seventy-five women who had abnormal Pap results and needed initial colposcopy completed telephone interviews; 40 completed a precolposcopy questionnaire and 35 completed a postcolposcopy questionnaire. MAIN OUTCOME MEASURES: Clients' concerns and coping strategies were assessed after they learned their Pap results were abnormal, the day before colposcopy, and the day after the procedure. RESULTS: Women's primary concerns involved not understanding the Pap results, cancer, or infertility. Coping strategies used most, and rated as helpful throughout the experience, were seeking social support and distraction. CONCLUSIONS: Nursing interventions can be designed to improve women's understanding of the meaning of abnormal Pap results, address concerns about abnormal Pap results, and encourage women to use social support and distraction while awaiting colposcopy.

Screening for cervical cancer: a new scope for general practitioners? Results of the first year of colposcopy in general practice.

A survey was carried out over one year of all the women who attended a colposcopy clinic in a general practice. During the year 1254 women underwent cytological screening in the practice and 197 of these underwent colposcopy. Of 79 women with abnormal smears that suggested cervical intraepithelial neoplasia, 62 (79%) were confirmed by biopsy to have cervical premalignancy. In addition, the remaining 118 women with normal or inflammatory smears underwent colposcopy either because of their history or because they requested the investigation. A general underestimate of cervical intraepithelial neoplasia when cytology alone was used was discovered. Seven out of 28 women with inflammatory smears were found to have important cervical premalignancy. Mildly dyskaryotic smears led to a falsely reassuring estimate of the degree of severity of cervical lesions. Seven out of 13 patients who underwent colposcopy because they were thought to be at high risk of neoplasia because of a history of genital warts, unexplained recurrent cystitis, heroin abuse, or immunosuppression had cervical intraepithelial neoplasia proved at biopsy. This report shows that both in screening for and in the follow up of known cervical disease a normal smear cannot guarantee normal pathology. Diagnostic colposcopy is a valuable complementary investigation that could be carried out in a general practice.

Management guidelines for women with normal colposcopy after low grade cervical abnormalities: population study.

OBJECTIVES: To develop an evidence based protocol for the follow up of women with low grade cervical abnormalities for whom treatment is not immediately indicated. DESIGN: Population outcome study. SETTING: Colposcopy clinic of an inner city teaching hospital. PARTICIPANTS: 566 women with low grade cytological abnormalities who were not treated at a first visit to the colposcopy clinic, followed up for a total of 881 years. MAIN OUTCOME MEASURES: Resolution of abnormalities, persistence of disease, and treated disease. RESULTS: Abnormalities resolved in 306 (54.1%) women, whereas 138 (24.4%) had persistent disease and 122 (21.5%) were subsequently treated. Colposcopic opinion, smear test results, age, smoking history, and number of pregnancies were all significantly related to outcome. Logistic regression analysis produced a model that correctly identified 70% of women whose abnormalities resolved. Only 23 of 295 women (7.8%) with a normal cervix on colposcopy and a smear without dyskaryosis at a first visit were treated by the end of the observation period. CONCLUSIONS: Women referred with low grade cytological abnormalities who have a normal cervix on colposcopy and a negative or borderline repeat smear test result may be discharged from the colposcopy clinic. We propose a follow up protocol that could safely avoid unnecessary visits to a clinic.

The value of primary colposcopy in genitourinary medicine--a six year review.

OBJECTIVE: To evaluate the effectiveness of primary colposcopy in the genitourinary medicine setting by comparing the cervical cytology and punch biopsy results for women identified as having an abnormal cervical transformation zone. METHOD: A retrospective audit of six years' findings in primary colposcopy was carried out. The punch biopsy findings of 1338 women were compared with their last cervical cytology results. A small sample of biopsies were subjected to in situ hybridisation for human papilloma virus types 6, 11, 16, 18 and cytomegalovirus. RESULTS: The tabulated results demonstrated the variability between histology and cytology. This was explored with reference to other studies. The viral typing showed the dominance of low oncogenic risk human papilloma virus types. CONCLUSION: The findings are discussed against the overall concept of sexual health. Primary colposcopy facilitates empowerment of the patient and her partner through the opportunity for demonstration and explanation of disease processes and options for management. Experience and expertise gathered in six years of primary colposcopy confirm the value of primary colposcopy not only in improved diagnosis and management but also in teaching, audit and research.

Evaluation of adjunctive HPV testing by Hybrid Capture II in women with minor cytological abnormalities for the diagnosis of CIN2/3 and cost comparison with colposcopy.

BACKGROUND: As a proportion of high grade cervical intraepithelial neoplasia (CIN2/3) are associated with equivocal cervical smears, which show borderline or mild dyskaryosis, follow up with repeat smears, colposcopy and biopsy is required. Since infection with oncogenic Human Papilloma Virus (HR HPV) has been found to be associated with the development of cervical cancer, HRHPV testing appears to be an alternative. OBJECTIVE: The present study assesses if HRHPV testing can predict CIN2/3 in women referred for mild dyskaryosis and borderline cytological changes in an health authority with a referral policy to colposcopy after one single mild dyskaryotic Pap smear. STUDY DESIGN: The HPV DNA Hybrid Capture II (Digene/Abbott, Maidenhead) was evaluated on 110 consenting women with mild dyskaryosis and 23 women with persistent borderline changes, who were referred for colposcopy between May and November 2001. A cost comparison between two referral policies was performed. RESULTS: CIN2/3 was diagnosed histologically in 30 of 133 women (22%) with minor cytological abnormalities. As the Receiver Operator Characteristics plot suggested a cut-off of 3 pg/ml the HRHPV HCII was evaluated at 3 RLU (relative light units) and at the manufacturer's recommendation of 1 RLU. At both cut-offs sensitivity and negative predictive value were high at 97%. Specificity was low at 37% at a cut-off of 1 pg/ml and 46% at a cut-off of 3 RLU. To remain cost neutral in comparison to immediate colposcopy the costs for one HR HPV HC II must not exceed pound 34.37 per test at a cut off of 3 pg/ml. CONCLUSION: The negative likelihood ratio (NLR) was of good diagnostic value with 0.089 at 1 RLU and 0.072 at 3 RLU, which reduces the post-test probability for CIN2/3 to 2% in this population. Women with minor cytological disorders can be excluded from colposcopy on a negative HR HPV result.Specificity can be improved by restricting HR HPV testing to women with persistent borderline cytological changes or to women over 30 years.

Telephone counseling improves adherence to colposcopy among lower-income minority women.

PURPOSE: A randomized trial was conducted to evaluate the impact of a telephone counseling intervention to improve patient adherence to colposcopic examination for suspected cervical intraepithelial neoplasia (CIN). METHODS: Subjects were lower-income, minority women who missed a scheduled initial appointment for colposcopy at an urban medical clinic. Patients were randomly assigned to either a control condition (n = 42) or a telephone counseling condition (n = 48). The 15-minute, structured telephone counseling intervention protocol addressed educational, psychosocial, and practical barriers to colposcopy adherence. RESULTS: The most common patient-reported barriers to colposcopy adherence included a lack of understanding of the purpose of colposcopy (50%), worry about or fear of cancer (25%), and forgetting (23%). Telephone counseling was found to be highly effective in addressing these barriers and improving adherence to diagnostic follow-up and treatment. Of patients in the control condition, 43% complied with a rescheduled colposcopy appointment, compared with 67% in the telephone counseling condition. Logistic regression analysis indicated that the effect of telephone counseling was independent of sociodemographic confounder variables (odds ratio = 2.6; P less than .003). Additionally, 74% of patients who received the initial telephone counseling adhered to recommended treatment, compared with 53% of patients in the control condition. CONCLUSION: Brief, structured telephone contact may be a cost-effective mechanism for improving adherence to diagnostic follow-up and treatment for a variety of cancer screening tests.

Appraisal theory and emotional sequelae of first visit to colposcopy following an abnormal cervical screening result.

OBJECTIVES: Attendance at colposcopy following an abnormal cervical smear is potentially a highly distressing event. This study evaluates the role of cognitive appraisal components (Lazarus, 1991; Smith et al., 1993) in explaining emotional reactions to this event. We also compare the psychological sequelae of immediate treatment at first colposcopy (See and Treat, ST) vs. colposcopy with treatment deferred to a later date (Diagnose and Defer, DD). METHOD: One thousand and eighty-five women referred for colposcopy completed a questionnaire assessing appraisal and emotion following their attendance. Clinical data were abstracted from medical records and social deprivation scores were estimated from postal code information based on normative data. RESULTS: Diagnosis and cognitive appraisals were each significantly associated with emotion, together accounting for between 3 and 15% of variance in different emotions. Specific patterns of appraisal explained specific emotions in line with theoretical predictions. Women with Cervical Intraepithelial Neoplasia (CIN) 2 or CIN 3 undergoing 'ST' were less anxious, less embarrassed and significantly more relieved compared with a matched sample of women undergoing 'DT', and perceived their first appointment as more motivationally congruent. CONCLUSION: Diagnosis, motivationally incongruent experiences and low emotion-focused coping potential are the most important determinants of anxiety after colposcopy. 'See and Treat' appears to have a positive psychological impact by increasing motivational congruence.

[The suitability of digital colposcopy for telematic applications].

Since carcinoma of the cervix is one of the most common cancers in women, screening of the cervix has acquired considerable importance. Colposcopy is a simple diagnostic method of detecting suspicious changes at an early stage. Shortcomings of this method are its low specificity and high inter- and intra-observer variability. A clinical pilot study was therefore carried out to investigate the advantages of a digital colposcopic system comprising a binocular colposcope coupled to a CCD camera and a computer. The aim of the study was to evaluate the reliability of diagnostic findings of the cervix obtained with digital colposcopy in comparison with standard binocular colposcopy, and to assess its suitability for telematic applications (teleconsultation, telediagnostics, treaching). A total of 315 patients were examined and statistically analysed. The patients were first submitted to a conventional colposcopic examination and a diagnosis was established. During the colposcopic examination camera images were stored on a computer, on the basis of which a second physician experienced in colposcopy reviewed the initial diagnosis. The primary and secondary findings of each patient were classified into 4 categories and compared following the Rome classification system. Agreement between the primary and secondary diagnosis was established in 69% of the cases (kappa = 0.60 +/- 0.03). No bias was observed in terms of under- or overrating. The percentage of non-assessable colposcopic examinations was 9.2%. Digital colposcopy is therefore suitable for reproducing diagnostic findings on the computer, given adequate digital image quality and a suitable classification model. The method has clear advantages with regard to follow-up, internal quality control of the diagnosis, and the training and further education of physicians and students. In the future, telecolposcopy may open up new opportunities in gynaecology.

[Sensibility and specificity of cytology and colposcopy exams with the histological evaluation of cervical intraepithelial lesions].

OBJECTIVE: To evaluate the correlation of cytopathological and colposcopycal diagnosis with the histopathological analysis from biopsy. METHODS: 80 patients from the colposcopy ambulatory of the Hospital e Maternidade Santa Brígida de Curitiba, PR, were selected. Those patients were sent to colposcopy under the following criteria: 1) previous abnormal cytopathological exams, 2) Indicative clinical data or, 3) Suspected lesions on gynecological exam. The statistical significance analysis of the results was done using the chi-square test. Sensibility, specificity, positive predictive value (PPV) and negative predictive value (NPV) were also determined. RESULTS: The patients' mean age was 30.2 (+/-10.9). Cytopathological capability of identifying lesions was 50% when compared to histology. Its specificity was 77%, the sensibility 41%, the PPV 74%, and the NPV 45%. Colposcopy capability of identifying lesions was 50%. Its sensibility, specificity, PPV and NPV were 96%, 19%, 65% and 75% respectively. The two methods associated were capable of identifying 63% of the lesions. CONCLUSIONS: Cytopathology was a high specificity exam, while colposcopy from those selected patients had a high sensibility. Colposcopy association with cytopathological screening, on those selected patients, significantly raises the diagnostic accuracy of cervical cancer precursor lesions.

Colposcopy in assessment of the natural history of prospectively followed-up human papillomavirus (HPV) lesions in the uterine cervix.

As a part of the long-term prospective follow-up study conducted in our clinic since 1981 for women with cervical HPV (Human papillomavirus) infections (either with or without cervical intra-epithelial neoplasia, HPV-CIN and HPV-NCIN, respectively) the colposcopic data on 292 consecutive patients with a mean follow-up of 16 months are reported. The results are based on 786 colposcopies performed at 6-month intervals according to conventional methods. Colposcopic findings are categorized into one of the following patterns: normal, warty, punctate, mosaic, leukoplakia, and combination. Colposcopic pattern bore an excellent correlation to the natural history (clinical course) of the HPV lesions, in that colposcopy was normal in 75% of the regressing lesions, in 38% of the persistors, and in only 16% of the progressors. The percentage of regression increased parallel with the frequency of normal pattern during the follow-up. Leukoplakia and combination were the two most frequent (55.7%) patterns in progressor lesions, as compared with only 12.9% in regressors and in 33.2% of the persistors. The same was true of the 15 lesions progressing into carcinoma in situ (CIS), and treated by cone. In the progressor lesions, an abnormal colposcopy pattern was disclosed in 65-100%, as compared with 14-35% only in the regressors. The present study provides evidence that colposcopy is an applicable and relatively accurate diagnostic method for assessing cervical HPV lesions. Colposcopy also seems to have some prognostic value in the follow-up of these lesions, as shown by the fact that normal colposcopic pattern is frequently associated with regression, whereas leukoplakia and combination are encountered more frequently than others in HPV lesions with CIN, shown to be more prone to progress during the follow-up.

Patient acceptance and the psychological effects of women experiencing telecolposcopy and colposcopy.

BACKGROUND: The purpose of the study was to assess patient acceptance and psychological effects in women experiencing telecolposcopy compared with colposcopy. METHODS: Convenience samples of 150 and 263 women scheduled for colposcopy or telecolposcopy, respectively, completed questionnaires assessing anxiety (Prime MD), depression [Center for Epidemiologic Studies/Depressed Mood Scale (CES-D)], health beliefs and concerns, coping style (Miller Behavioral Style Score) and examination acceptance and satisfaction. Test scores and subject responses were compared using the t test and Wilcoxon rank sum test. RESULTS: Mean scores representing mild anxiety (1.3 and 1.2, P =.7) and mild depression (35.4 and 36.3, P =.4) were reported for the telecolposcopy and colposcopy groups, respectively. The telecolposcopy group indicated significantly greater mean scores for the examination, saving them time and money compared with the colposcopy group. Women in both groups were highly satisfied with their examinations and care. CONCLUSIONS: In general, women reported very high levels of satisfaction with telecolposcopy and colposcopy. Potential savings of time and money and improved health care were considered of particular value to women examined by telecolposcopy. Telecolposcopy seems to be well accepted by rural women.

Is default from colposcopy a problem, and if so what can we do? A systematic review of the literature.

It has been reported that many women referred to outpatient colposcopy clinics fail to attend for their appointments. The aim of this paper is to search the literature to assess the extent of default from colposcopy and to identify interventions, suitable for implementation within primary care, to reduce the proportion of women defaulting. Searches were performed on MEDLINE, PsychLIT, Bids and Cancerlit from 1986 to September 1997 using the terms colposcopy or cervical/Pap smear in association with default, non-attendance, adherence, patient compliance, treatment refusal, patient dropouts, attendance, barriers or intervention. The inclusion criteria for primary papers were that they contained data that enables the calculation of default rates for colposcopy or the results of interventions aimed at improving the default rates. Thirteen publications describing default rates and four describing interventions were included as primary papers. Combining the data from these studies suggests default rates of 3%, 11%, and 12% for assessment/treatment visits, first review, and second review respectively. The intervention studies suggested a need to tailor the intervention to the population and the type of information to suit the individual. Varying definitions make comparison of default rates difficult, and the use of a crude non-attendance rate may result in an overestimate of default rates. The vast majority of women invited to colposcopy eventually attend. It is questionable if there is a need for interventions to increase compliance. Where necessary, greater cooperation across the primary/secondary care interface and use of the extended primary care team may be a more cost-effective means of increasing compliance.

Colposcopy, cytology and histology in the diagnosis of squamous intraepithelial lesions of the cervix.

OBJECTIVE: To compare colposcopic findings to cytologic and histological diagnoses in women with colposcopic reports of ANTZ and/or HPV infection. METHODS: Among 791 hospitalized women referred for colposcopic examination, colposcopy showed ANTZ grade 0-2 and/or HPV infection in 271 patients (34.26%). Only 153 were fully investigated by colposcopy, cytology (under colposcopic observation) and histology (target punch biopsy: 109 patients; surgical specimens of hysterectomy: 42 patients; conization: 2 patients). Cytological and histological diagnoses were reported according to the Bethesda System. RESULTS: 132/153 Pap smears were estimable for sampling adequacy; 44/63 resulted as normal and were histologically positive for LSIL [1]. Five LSIL-positive Pap tests were negative on histology (false negative and false positive rate of 33.33% and 3.78%). The pap test was diagnostic for intraepithelial neoplasia in 34/65 cases (53.3%) and for invasive cancer in 6/11 cases (54.5%). In 67/132 cases (50.8%) adequate-for-sampling Pap smears could not predict the exact diagnosis. On the other hand, 108/141 patients with colposcopic evidence of ANTZ/cancer showed histological SIL or invasive neoplasm (76.59%): ANTZ 1 was associated to LSIL and HSIL in 74.1% and 2.4%; ANTZ 2 to LSIL, HSIL and invasive cancer in 41%, 30.76% and 10.3%. Colposcopic suspicion of invasive cancer in 8 patients was histologically demonstrated in 7 (87.5%); colposcopic diagnosis of HPV infection was confirmed in 10/12 (83.4%). CONCLUSION: A better correspondance was shown between colposcopy and histology than between cytology and histology in the diagnosis of SIL. We suggest a routine colposcopy investigation for all patients admitted to a gynecological clinic and we believe it is very important to take Pap smears under colposcopic observation if colposcopy and cervical smears are performed in the same sitting.

Screening for high-grade cervical intra-epithelial neoplasia and cancer by testing for high-risk HPV, routine cytology or colposcopy.

The validity of testing for high-risk types of human papillomavirus (HPV) in cervical cancer prevention programs is undetermined. We compared the performance on primary screening of HPV DNA testing, cytology and colposcopy in detecting cervical intra-epithelial neoplasia (CIN) grade 2 or 3 or cancer. A cohort of 4,761 women, median age 35 years, was screened by routine cytology, routine colposcopy and testing for high-risk HPV by a PCR-based method. Within an 8-month period, women with abnormal findings on cytology or screening colposcopy or in whom high-risk HPV types were detected were referred for colposcopy and biopsy. Women negative on all initial screening tests were followed by a second screening examination. To correct for work-up bias, the true prevalence of CIN 2 or 3 or cancer was estimated by projection from histologically verified subgroups. Cervical biopsies were taken in 364 women (7.6%), of whom 114 (2.4%) showed CIN 2 (n = 34) or CIN 3 (n = 71) or cancer (n = 9). High-risk HPV testing achieved bias-corrected performance measures of 89.4% sensitivity, 93.9% specificity, 35.8% positive predictive value and 99.6% negative predictive value. Bias-corrected rates of true- and false-positives by high-risk HPV testing compared to cytology (colposcopy) were about 4.5 (6.7) and 19.1 (7.4) times higher, respectively. The quality of routine cytology was controlled by computer-assisted review, and the observed number of true-positives more than doubled after adding automated review results. In middle-aged women, testing for high-risk HPV types, particularly when negative, may be used to increase the screening interval in programs for secondary prevention of cervical cancer.
