Cervicography

Background

Cervicography involves the use of a specialized camera that is described as easy to use and not requiring experience in colposcopy. The photographs, referred to as cervigrams™, are static photographic images of the cervix similar to those seen during low-level magnification colposcopy. The images are sent to a central laboratory (National Testing Laboratories, the worldwide exclusive licensee of the product) for interpretation by colposcopists who have received specialized training in interpretation of cervigrams. Cervigrams are interpreted as negative, atypical, positive, or defective.

Cervicography has been investigated in three general settings:

  • As an alternative to Pap smear screening as a primary screening technique for cervical cancer. This application has been investigated primarily in "resource poor" areas that do not have cytology expertise to interpret Pap smears.
  • As an adjunct to routine Pap smear screening to improve the sensitivity of Pap smear screening for cervical cancer. For example, it is estimated that negative cytology reports are issued on 20% or more of all invasive cervical cancers.
  • As a triage technique for colposcopy in patients found to have low-grade lesions on Pap smear specimens.

The management of low-grade lesions, i.e., atypical squamous cells of uncertain significance (ASCUS), has been a subject of investigation. For example, colposcopy is an option for further workup of ASCUS lesions, and yet at colposcopy only 20% of these patients actually have a high-grade lesion. Furthermore, many low-grade lesions that may prompt colposcopy will spontaneously regress. If cervicography can be used to identify which ASCUS cytology results are most likely to harbor higher grade lesions and thus need colposcopy and biopsy, unnecessary colposcopies in patients with innocuous cytologic abnormalities would decrease. Other triaging strategies include repeat Pap smears or evaluation for human papilloma virus (HPV) infection.

U.S. Food and Drug Administration (FDA) Approval or Marketing Clearance of Devices

In June 1982, the Cerviscope Optical System (Fotomedics) was cleared for marketing by the FDA through the 510(k) process. The FDA determined that this device was substantially equivalent to existing devices for viewing tissues of the vagina and cervix.

Speculoscopy

Background

The procedure for conducting a speculoscopy involves several steps. First, the cervix is washed with 3–5% acetic acid. The examining room lights are then dimmed, and the cervix is visually examined using 5X magnifying loupes. The examination takes place using a disposable blue-white chemiluminescent light that is attached to the inner aspect of the upper speculum blade. Epithelial cells with increased keratinization and nuclear cytoplasmic ratios have an increased light reflection and appear white, in clear distinction to the dark blue of the normal epithelium. The presence of white lesions is considered a positive result; these areas may then be sampled for cytologic evaluation.

Speculoscopy must be distinguished from other methods of enhanced visual inspection of the cervix, including cervicography and colposcopy. Cervicography involves taking a picture of the cervix with a special macrolens strobe-flash camera after the cervix is swabbed with acetic acid. The photograph is then sent to a central laboratory for interpretation. Colposcopy involves the visual inspection of the cervix using a lighted microscope; unlike cervicography and speculoscopy, colposcopy has not been proposed as a primary screening method.

Two clinical roles of speculoscopy have been proposed, both as an adjunct to conventional cervical cancer screening and as a technique to select women with atypical cytological findings for further evaluation for colposcopy. For example, although cervical cancer screening is considered among the most successful cancer screening programs, it is still considered to be relatively insensitive; i.e., Papanicolaou (i.e. Pap) smear cytology is associated with false-negative results ranging from 15% to 55%. Speculoscopy is thought to potentially increase the sensitivity of cervical cancer screening by enhancing the visual inspection of the cervix.

Management of women with atypical Pap smears has evolved over the past several years, with a focus on various strategies to select those women with high-risk lesions who would benefit from further evaluation with colposcopy. Screening for human papillomavirus (HPV) is increasingly accepted as part of initial cervical cancer screening for women aged 30 years and older. In 2012 guidelines developed jointly by the American Cancer Society (ACS), American Society for Colposcopy and Cervical Pathology (ASCCP), and American Society for Clinical Pathology (ASCP), HPV and cytology “co-testing” every 5 years is the preferred screening strategy recommended for women aged 30-65 years; cytology alone every 3 years is included as an acceptable screening alternative. (19) Similarly, the United States Preventive Services Task Force (USPSTF) 2012 cervical cancer screening guideline recommends screening with a combination of cytology and HPV testing every 5 years for women for women aged 30 to 65 years who want to lengthen their screening interval. (20) Both 2012 guidelines recommend cytology only for women aged 21 to 29 years.

Regulatory Status

In 1995, speculoscopy using the Speculite® (Trylon Corp.; Monarch Beach, CA), a chemiluminescent light source, was cleared for marketing by the FDA through the 510(k) process. Later in 1995, the Pap Plus Speculoscopy (Trylon Corp.) was also cleared for marketing by the FDA and was later renamed PapSure®. It combined the Speculite device with a vaginal speculum, which is used for obtaining a Pap smear. In 2002, Watson Diagnostics, Inc. acquired the rights to PapSure and Speculite from Trylon Corporation, and they continue to market the combination device as PapSure. Speculite is intended for use only in conjunction with the Pap smear and is indicated for use in women currently recommended to undergo cervical screening with Pap smears.

Speculoscopy, with or without directed sampling, is considered experimental, investigational and unproven as an adjunct to a program of cervical cancer screening including initial or repeat Papanicolaou (Pap) smears or DNA testing for human papillomavirus (HPV).

Rationale

Cervicography

Cervicography has been the subject of several randomized studies that have studied its use in various settings, i.e., as a primary screening technique, an adjunct to Pap smear screening as a primary screening technique, and a triaging strategy for patients found to have low-grade lesions on Pap smear.

Cervicography as an Alternative to Pap Smear as a Primary Screening Technique

Schneider and colleagues reported on a study comparing cervicography with conventional Pap smear, a conventional Pap smear interpreted with the aid of PapNet (neural network semiautomatic screening device), and a Pap smear prepared from a ThinPrep solution and interpreted conventionally. (1) The study included 8,460 women from Costa Rica, considered a high-risk population for cervical cancer. Patients were referred for colposcopy and potential biopsy if there was an abnormal cytologic result by any 1 of these 3 methods. The sensitivities and specificities of the cytologic testing and cervicography for the most clinically important high-grade lesions compared to a referent diagnosis* are summarized in the following table.

Table 1. Sensitivity of Cervicography and Cytology to Detect High-Grade Lesions

 

Sensitivity of Cytology, %

Sensitivity of Cervicography, %

High-grade lesions; women older than 50 years

84.6

26.9

High-grade lesions; women younger than 50 years

75.5

54.6

*Referent diagnoses were made based on histologic, cytologic, and cervicographic results.

As noted in Table 1, the sensitivity of cervicography sharply drops among older, predominantly postmenopausal women. This observation is explained by the cephalad movement of the transformation zone in postmenopausal women. The transformation zone is the site of origin of most cervical cancers, and as it moves cephalad into the cervical canal, it is no longer well visualized with cervicography. The authors concluded that cytologic testing performed better than cervicography for the detection of high-grade intraepithelial lesions, while cervicography was only marginally better in the detection of invasive cervical cancer.

Cervicography as an Adjunct to Primary Pap Smear Screening

The combined use of Pap smear screening, cervicography, and human papilloma virus (HPV) testing has been investigated as a technique to reduce the false negative rate of Pap smear screening alone.

Autier and colleagues performed a randomized study comparing cytology alone versus cytology and cervicography. (2) A total of 5,550 women considered at low risk of cervical neoplasia were randomized to one of the screening strategies and rescreened 1 year later with combined cytology and cervicography. Women positive for either of the 2 initial screening tests were referred for colposcopy-biopsy. The principal study endpoint was the rate of histopathologically confirmed cervical intraepithelial neoplasia (CIN) lesions. In the cytology only group, 13 of the 2,772 (0.47%) Pap smears were read as abnormal. In contrast, in the combined group, 12 Pap smears were read as abnormal in addition to 101 cervigrams that were read as abnormal. No woman was positive for both Pap smear and cervigram. A total of 13 patients in the cytology alone group were referred to colposcopy, compared to 113 in the combined group. Cervical intraepithelial neoplasia grade 2-3 (CIN 2-3) was identified in 4 of the patients in the cytology alone group compared to 6 in the combined group. Therefore, the majority of the patients with abnormal cervigrams were either found to have no lesion or CIN 1 on subsequent colposcopy. CIN 1 lesions are generally thought to be transient in nature and require no specific treatment, but may be followed up with repeat Pap smears. While the addition of cervicography to cytology improved the detection of CIN 1 lesions, it did so at a cost of a decreased specificity. In addition, detection of CIN 2 and 3 lesions represents the most clinically significant target of screening.

Costa and colleagues reported on the results of 992 patients undergoing routine Pap smears who underwent simultaneous cervicography and HPV testing. (3) All patients also underwent colposcopy as the reference tool. The combination of Pap testing with cervicography resulted in an increase in sensitivity but a decrease in specificity. The positive predictive value of combined Pap and cervicography (43%) was similar to that of Pap smear alone (45%).

Cervicography as a Triaging Strategy in Women with Atypical Squamous Sells of Undetermined Significance (ASCUS) or Low-Grade Squamous Intraepithelial Lesion (LSIL) on Pap Smears

The ASCUS/LSIL Triage Study (ALTS) was a multicenter, randomized trial that compared three different management strategies for 3,488 women with either ASCUS or LSIL on an initial Pap smear. (4) The strategies included: 1) immediate colposcopy (considered the reference standard), 2) triage to colposcopy based on the results of HPV testing, or 3) triage based on cytology results alone. The main study endpoint was detection of CIN 3, since there is a general consensus that this lesion is at high risk of progressing to invasive cancer and requires definitive treatment. All patients also underwent cervicography, as a "fail safe" mechanism in the noncolposcopy groups to prevent a missed cancer diagnosis. The cervicography results were then interpreted separately as a triaging technique for mildly abnormal cervical cytology results by comparing the results of the cervicography with the histologic results of those patients who underwent colposcopy. (5) Cervigrams were categorized as defective, negative, atypical, or positive. Positive cervigrams were further subdivided into additional categories: positive, LSIL, high-grade intraepithelial lesion (HSIL), or cancer. If one considered an atypical cervigram as an indication for referral to colposcopy, the sensitivity of cervicography to detect CIN 3 lesion (i.e., high-grade lesion requiring treatment) was 79.3% and would have required the referral of 41.8% of women for colposcopic examination. When increasing the threshold for colposcopic referral to cervigrams interpreted as positive for LSIL, the sensitivity of detected CIN 3 dipped to 65.8%, requiring referral of 26.5% of women for colposcopic exam. In the ALTS trial, cytology and HPV testing were explored as triaging options. Table 2 shows the comparative results:

The authors concluded that cost-utility analyses will determine whether and when cervicography, compared with other clinical options, is useful in the management of mildly abnormal cervical cytology results.

Other information

In 2001, the American Society for Colposcopy and Cervical Pathology (ASCCP) published guidelines for the management of women with cervical abnormalities, in part based on the results of the ALTS study. These guidelines do not recommend cervicography as a triaging strategy. (6, 7)

The U.S. Preventive Services Task Force specifically does not recommend cervicography as part of a cervical cancer screening program. (8) The Task Force states that the sensitivity of cervicography is similar to that of Pap smears, but that both the specificity and positive predictive value are considerably lower than Pap smears. The positive predictive value is only about 1%–26%, and up to 10%–15% of cervigrams are unsatisfactory in quality. The Task Force concludes that “There is insufficient evidence to recommend for or against routine screening with cervicography.” This recommendation was issued in 1996.

Summary

Cervicography alone has an inferior sensitivity compared to cytology, and therefore is not recommended in settings where adequate cytology services are available. As an adjunct to Pap smear screening, cervicography may increase the sensitivity for detecting cervical abnormalities, but will decrease the specificity, potentially resulting in increased referrals for colposcopy. As a triaging strategy for patients with mildly abnormal cytology results, cervicography is a promising technique that appears to be similar in terms of positive and negative predictive values compared to other options, including repeat cytology or HPV testing. However, if the original Pap smear was collected in a liquid medium, subsequent HPV testing in patients whose cytology was mildly abnormal could be done on the same sample. Therefore, these patients do not need to return for a repeat office visit. Both repeat Pap smear and cervicography would require an additional office visit. At present, no clinical guidelines are available from the American College of Obstetricians and Gynecologists, U.S. Preventive Services Task Force, or related organizations that recommend the use of cervicography in any of the above clinical situations.

Additional Literature Review

Ferris and colleagues compared cervicography to on-site colposcopy and telecolposcopy in 264 women. (9) The authors found no statistically significant difference in rates of agreement or sensitivity and specificity for each of the screening methods when CIN 1 cases were considered. However, when evaluating CIN 2 and 3 cases, on-site colposcopy out-performed cervicography in rate of agreement and sensitivity (Table 3). Therefore, the authors indicated telecolposcopy detected more cervical neoplasia than cervicography.

In Cronje, 1,286 women were each screened with cytologic examination, cervicography, direct acetic acid test, and speculoscopy. (10) Results were compared to histologic examination to identify a suitable method for screening in a developing country. The authors concluded that none of the methods were individually sufficient for screening in a developing country. Cervicography results were 48.9 for sensitivity and 87.5 for specificity and were noted to be inadequate for the study purpose due to the low specificity. Finally, Howard and colleagues compared the diagnostic yield of cervicography and HPV testing among 304 women with ASCUS lesions detected on Pap smears. (11) The adjunctive tests were compared to the gold standard of colposcopy. The authors concluded that while both adjunctive tests increased the sensitivity of cytology, there was insufficient power to determine whether observed sensitivities were statistically significantly higher than expected, given that the adjunctive tests could improve the sensitivity by chance alone.

Studies continue to evaluate the potential role of cervicography in settings where adequate cytology services are not available. In addition, studies are evaluating the potential impact of combining cervicography with other tests as a risk-stratification or triage technique. For example, Wang and colleagues reported that combining results of liquid-based cytology, HPV testing, and cervicography could help determine the risk of subsequent development of cervical precancers. (12) Before this could be used in practice, replication/validation of these findings would be needed.

Two studies of interrater reliability using cervigrams were published; both used convenience samples of cervigrams obtained for other studies. In the first, 72 experienced (4 expert) colposcopists from 5 countries reviewed a sample of 50 cervigrams, representing a spectrum from normal to cancerous, for the presence of lesions and the site of suggested biopsy. (13) Their results were compared to those of the consensus (not histology). Agreement was 70% (65%–75%), which the authors concluded was sufficient for all centers to participate in a trial assessing the best management strategy for biopsy proven CIN1. The second study involved 919 cervigrams from the ASCUS-LSIL Triage Study (all subjects referred to the study had either ASCUS or LSIL). (14) Each cervigram was evaluated by 2 expert colposcopists for lesion severity and the number of lesions. The evaluators had complete agreement in 56.8% of cases, disagreement between high- and low-grade lesions in 37.8%, and absolute disagreement in 5.3%. HPV status and age were predictive of agreement. The authors concluded that caution is needed when using static images, even of high quality, for teaching and testing of colposcopists. Although neither study was intended to assess the screening capacity of cervicography, they illustrate challenges for the technology.

A multispectral digital colposcope, a modified colposcope with a video camera adapter and automated digital image analysis, is in development, and a report of the performance of this technology in a pilot study of 29 patients was identified. (16) Sensitivity was reported at 79% and specificity was 88%. Much larger study populations will be necessary to evaluate the test characteristics of this emerging technology.

Chen and colleagues conducted a study in Taiwan evaluating cervicography as an adjuvant screening tool for women with precancerous lesions identified by Pap smear. (17) A total of 125 women were enrolled, and 119 underwent cervicography. The investigators created a digital cervicography instrument using a digital camera with a macro lens and a circular-shaped continuous light source. They evaluated images in-house using the Reid colposcopic index (RCI) scoring system. Scores were dichotomized to a total RCI score of 0–2 (predictive of mild dysplasia) and a total RCI score of 3–8 (predictive of moderate or severe dysplasia). There were 112 cases of ASCUS or LSIL (by the Pap smear); 92 of these received an RCI score of 0–2 and 20 received an RCI score of 3–8. Of the 7 cases of HSIL (by the Pap smear), 1 received an RCI score of 0–2 and 6 received an RCI score of 3–8. A McNemar test to evaluate changes in classification after performing digital cervicography was statistically significant (p<0.01). The investigators used findings from digital cervicography primarily to show patients visual images with the goal of reducing their anxiety over having an abnormal Pap smear. No conclusions were made regarding the impact of digital cervicography on patient management, e.g., referral to colposcopy. It is important to note that the Chen study did not use standard cervicographic equipment or analysis methods so it is not clear whether their technique would be considered cervicography.

Summary

There remains insufficient evidence on the reliability and diagnostic accuracy of cervicography, and insufficient evidence that cervicography has a benefit on net health outcome. Moreover, cervicography may no longer be commercially available. The continued existence of Fotomedics, the manufacturer of the FDA-cleared Cerviscope Optical System and the National Testing Laboratories, previously mentioned as the worldwide exclusive licensee for analyzing cervigrams, could not be verified (e.g., no Web sites or current contact information were identified).

The 2006 update of the consensus guidelines for the management of cervical abnormalities by the American Society for Colposcopy and Cervical Pathology do not mention cervicography or cervigrams.(15) The U.S. Preventive Services Task Force has not updated their guidelines for cervical cancer screening since 2003.

Speculoscopy

Speculoscopy as an adjunct to routine cervical cancer screening

To determine the clinical performance of speculoscopy compared to conventional Papanicolaou (Pap) smear screening alone, speculoscopy must be evaluated in prospective studies of patients undergoing routine screening. Moreover, ideally, all patients would be referred to colposcopy, which is currently considered the gold standard. However, this type of testing is not feasible on a large scale, and thus it is likely that only patients with positive results on Pap smears or speculoscopy would then be referred to colposcopy. A search of the literature identified 4 prospective trials published in screening populations.

Edwards and colleagues conducted a multicenter trial in a health maintenance organization (HMO) setting in which 689 patients undergoing routine Pap smear screening immediately underwent a speculoscopy at the same office visit. The exam was performed by nurse practitioners and midwives. (21) Those with positive findings on either Pap smear screening (presence of atypical squamous cells of uncertain clinical significance [ASCUS] or intraepithelial lesions) or speculoscopy (presence of aceto-whitening) subsequently underwent colposcopy. A total of 9.9% of patients (n=68) had normal results on Pap smear screening but a positive finding on speculoscopy. This group of patients represents the potential incremental yield of adding speculoscopy to routine screening. The results of the colposcopy in this group showed high-grade lesions in 3 patients, low-grade lesions in 28 patients, and normal findings in 37 patients. The clinical significance of low-grade lesions is uncertain; it is thought that the majority may be related to benign human papillomavirus (HPV) infections or are otherwise self-limited. Therefore, a clearly clinically significant finding of a high-grade lesion was identified by speculoscopy alone in 3 of 689 patients (0.4%). The clinical significance of this increase is unclear, particularly in the context of an increase in the false-positive rate for referral to colposcopy (from 2.6% to 5.4%).

Wertlake and colleagues reported on the results of a larger trial of 5,692 women who received speculoscopy in addition to routine pelvic exam and cervical cancer screening. (22) Pap smears showing intraepithelial lesions were considered positive, and speculoscopy was considered positive if aceto-whitening was present. Note that unlike the Edwards et al. study, (21) this study did not consider ASCUS cells to constitute a positive Pap smear. A total of 839 patients with positive results on either test were referred for colposcopy. Of these, 648 patients (77%) were referred solely on the basis of speculoscopy results. Of the 839 referred for colposcopy, only 410 (51.3%) underwent the recommended colposcopy; of these 410 patients, 333 were identified only by speculoscopy. Among these 333 patients, 11 high-grade lesions were identified, while 154 had low-grade lesions, and 168 had findings that were interpreted as normal or reparative. Interpretation of these results is limited by the large number of dropouts in the study, but the results are similar to the above study; a marginal increase in the identification of high-grade lesions coupled with an increase in the false-positive rate for referral to colposcopy. Another similarly designed, prospective community-based study conducted in Italy reported similar results. (23) In this study of 3,300 women, an additional 407 women were referred to colposcopy on the basis of a positive speculoscopy alone. Of these, 6 high-grade lesions were found, 269 had normal colposcopy results, and 132 low-grade lesions were found. Consistent among all these studies is the increased detection of low-grade lesions by speculoscopy alone. As noted by Wertlake et al., "…the use of any of these visual aids [speculoscopy, cervicography, colposcopy] will require sound clinical algorithms for managing those patients with visual abnormalities only (Papanicolaou smear negative). Such algorithms are likely to be multifactorial, balancing the increase in disease detection with the potential for false-positive results.…"

A multicenter study from Asia, published in 2007, evaluated the combined use of speculoscopy and Pap smear (PapSure®) for cervical cancer screening. (23) The study enrolled 1,813 premenopausal and postmenopausal women who had not received a Pap smear in the previous 3 years; 112 did not meet the study criteria or were lost to follow-up, leaving results of 873 premenopausal and 828 postmenopausal (94%) women for analysis. Colposcopy was conducted in 870 randomly selected women with negative screenings and 214 women who had positive screening test results. Nineteen women were diagnosed with high-grade squamous intraepithelial lesions (HGSIL) on biopsy, resulting in a rate of 1.1% for the population of 1,701 women. Sensitivity of Pap smear alone was 53%, speculoscopy alone was 63%, and the combined sensitivity was 90%, identifying 17 of 19 cases of HGSIL. Combined testing decreased specificity from nearly 100% with Pap smear alone to 90%. The positive predictive value of combined testing was 8.8%, and the negative predictive value was 99.9%. Speculoscopy identified 7 additional positive cases of HGSIL of a total of 19 (equating to 0.4% out of the 1,701 women included in the study and 37% of the population with cervical cancer). When evaluated by menopausal status, results were significant for premenopausal women but not for postmenopausal women; however, this result is limited by the low number of positive cases (n=7) in the postmenopausal group. These results are consistent with earlier studies reviewed above, with a 0.4% increase in detection rate and a larger increase in the number of women being referred for colposcopy.

Speculoscopy as a technique to triage for colposcopy

Evaluation of this role of speculoscopy would require a prospective, controlled trial comparing the diagnostic performance of speculoscopy to current best practice which involves cytology and HPV testing. The results of 2 multicenter trials on speculoscopy have been published, both prior to the now-accepted strategy of using HPV testing as a triage strategy for colposcopy. The 2 studies are reviewed below.

Massad and colleagues reported on a multicenter study of 137 with atypical Pap smears who underwent colposcopy. (24) The exact nature of the atypia was not provided. Patients underwent Pap smear, followed by speculoscopy, and then colposcopy. Any acetowhite areas noted on the speculoscopy exam were considered positive. Of the 94 women who had positive colposcopy results, 73% and 27% had positive and negative speculoscopies, respectively. Using colposcopy as the gold standard, the sensitivity, specificity, and positive and negative predictive values for speculoscopy were 73%, 93%, 96%, and 62%, respectively. It is unclear how, based on this diagnostic performance, speculoscopy would be integrated into a program of cervical cancer screening. It is likely that a negative predictive value of 62% would be considered adequate to consider foregoing a colposcopy, and it is unclear how the positive predictive value of 96% would affect the decision to undergo colposcopy. The results are not compared with the alternative options of repeat cytology or HPV testing.

In a second study from the same group of investigators, 395 patients referred for colposcopy underwent a repeat cervical smear immediately followed by a colposcopy, performed by the same physician. (25) Histologic diagnoses were compared with cytology, speculoscopy, and colposcopy results. An antecedent acetowhite abnormality detected during speculoscopy was highly predictive (97% positive predictive value) of a subsequent abnormal colposcopy. This study has the same limitations as the earlier study by this research team.

Summary

There is insufficient evidence on the diagnostic accuracy of speculoscopy added to Pap smears compared to Pap smears alone. In addition, there is insufficient evidence on the diagnostic accuracy of speculoscopy for triaging women with a positive Pap smear to additional follow-up such as repeat cytology or HPV testing. Thus, speculoscopy is considered investigational.
