Abstract

Objective

To evaluate the diagnostic accuracy of the 2011 International Federation for Cervical Pathology and Colposcopy (IFCPC) colposcopic terminology.

Methods

The clinicopathological data of 2262 patients who underwent colposcopy from September 2012 to September 2016 were reviewed. The colposcopic findings, colposcopic impression, and cervical histopathology of the patients were analyzed. Correlations between variables were evaluated using cervical histopathology as the gold standard.

Results

Colposcopic diagnosis matched biopsy histopathology in 1482 patients (65.5%), and the weighted kappa strength of agreement was 0.480 (P<0.01). Colposcopic diagnoses more often underestimated (22.1%) than overestimated (12.3%) cervical pathology. There was no significant difference between the colposcopic diagnosis and cervical pathology agreement among the various grades of lesions (P=0.282). The sensitivity, specificity for detecting high-grade lesions/carcinoma was 71.6% and 98.0%, respectively. Multivariate analysis showed that major changes were independent factors in predicting high-grade lesion/carcinoma, whereas transformation zone, lesion size, and non-stained were not statistically related to high-grade lesion/carcinoma.

Conclusions

The 2011 IFCPC terminology can improve the diagnostic accuracy for all lesion severities. The categorization of major changes and minor changes is appropriate. However, colposcopic diagnosis remains unsatisfactory. Poor reproducibility of type 2 transformation zone and the significance of leukoplakia require further study.

The Lower Anogenital Squamous Terminology Standardization Project for HPV-Associated Lesions: background and consensus recommendations from the College of American Pathologists and the American Society for Colposcopy and Cervical Pathology.

Ritu Nayar, M H Stoler, David Wilbur … (2012)

The terminology for human papillomavirus (HPV)-associated squamous lesions of the lower anogenital tract has a long history marked by disparate diagnostic terms derived from multiple specialties. It often does not reflect current knowledge of HPV biology and pathogenesis. A consensus process was convened to recommend terminology unified across lower anogenital sites. The goal was to create a histopathologic nomenclature system that reflects current knowledge of HPV biology, optimally uses available biomarkers, and facilitates clear communication across different medical specialties. The Lower Anogenital Squamous Terminology (LAST) Project was cosponsored by the College of American Pathologists and the American Society for Colposcopy and Cervical Pathology and included 5 working groups; 3 work groups performed comprehensive literature reviews and developed draft recommendations. Another work group provided the historical background and the fifth will continue to foster implementation of the LAST recommendations. After an open comment period, the draft recommendations were presented at a consensus conference attended by LAST work group members, advisors, and representatives from 35 stakeholder organizations including professional societies and government agencies. Recommendations were finalized and voted on at the consensus meeting. The final, approved recommendations standardize biologically relevant histopathologic terminology for HPV-associated squamous intraepithelial lesions and superficially invasive squamous carcinomas across all lower anogenital tract sites and detail the appropriate use of specific biomarkers to clarify histologic interpretations and enhance diagnostic accuracy. A plan for disseminating and monitoring recommendation implementation in the practicing community was also developed. The implemented recommendations will facilitate communication between pathologists and their clinical colleagues and improve accuracy of histologic diagnosis with the ultimate goal of providing optimal patient care.

The accuracy of colposcopic grading for detection of high-grade cervical intraepithelial neoplasia.

L. Massad, Mark Schiffman, Jose Jeronimo … (2009)

To relate aspects of online colposcopic image assessment to the diagnosis of grades 2 and 3 cervical intraepithelial neoplasia (CIN 2+). To simulate colposcopic assessment, we obtained digitized cervical images at enrollment after acetic acid application from 919 women referred for equivocal or minor cytologic abnormalities into the ASCUS-LSIL Triage Study. For each, 2 randomly assigned evaluators from a pool of 20 colposcopists assessed images using a standardized tool online. We calculated the accuracy of these assessments for predicting histologic CIN 2+ over the 2 years of study. For validation, a subset of online results was compared with same-day enrollment colposcopic assessments. Identifying any acetowhite lesion in images yielded high sensitivity: 93% of women with CIN 2+ had at least 1 acetowhite lesion. However, 74% of women without CIN 2+ also had acetowhitening, regardless of human papillomavirus status. The sensitivity for CIN 2+ of an online colpophotographic assessment of high-grade disease was 39%. The sensitivity for CIN 2+ of a high-grade diagnosis by Reid Index scoring was 30%, and individual Reid Index component scores had similar levels of sensitivity and specificity. The performance of online assessment was not meaningfully different from that of same-day enrollment colposcopy, suggesting that these approaches have similar utility. Finding acetowhite lesions identifies women with CIN 2+, but using subtler colposcopic characteristics to grade lesions is insensitive. All acetowhite lesions should be assessed with biopsy to maximize sensitivity of colposcopic diagnosis with good specificity.

Strength of correlations between colposcopic impression and biopsy histology.

L.Stewart Massad, Yvonne Collins (2003)

The aim of this study was to determine the strength of the correlation between colposcopic impression and biopsy histology. In an urban referral clinic, colposcopy and directed biopsy were performed between July 1, 1996, and December 31, 1999, by residents supervised by board-certified attending obstetrician-gynecologists. Impression and biopsy were graded as benign, suggesting condyloma or koilocytosis, cervical intraepithelial neoplasia (CIN) grades 1-3, or cancer. The significance of association was assessed by chi(2) testing and the strength by kappa statistics. Colposcopies were performed on 2825 women, with colposcopic impression and biopsy grade known for 2112. Exact agreement was found in only 893 (37%) women, but results agreed within one grade in 1203 (75%). The association between impression and histology was significant (P < 0.001), but the strength of the correlation was poor (0.20). The positive predictive value of any colposcopic abnormality for any histologic abnormality was 80%. The negative predictive value of a benign colposcopic impression was 68%. The sensitivity of colposcopy with a threshold of any lesion detected was 89%, and the specificity was 52%. The sensitivity for CIN 2/3 was 56%. Colposcopy is imprecise, although useful in estimating lesion grade. Management decisions require biopsy.
