Inner Border-A Specific and Significant Colposcopic Sign for Moderate or Severe Dysplasia (Cervical Intraepithelial Neoplasia 2 or 3)

Performance of three colposcopic images for the identification of squamous and glandular cervical precursor neoplasias

Purpose

To evaluate prevalence and diagnostic performance of three colposcopic images to diagnose squamous and glandular cervical precursor neoplasias.

Methods

Cross-sectional study, conducted through analysis of stored digital colposcopic images. To evaluate the diagnostic performance of three images, herein named grouped glands, aceto-white villi, and atypical vessels, for detection of adenocarcinoma in situ (AIS) and cervical squamous intraepithelial neoplasias (CIN) grades 2 and 3, calculations of sensitivity, specificity, accuracy, positive likelihood ratio, receiver operating characteristic (ROC) curve, and area under the curve (AUC) were made, with their respective 95% confidence intervals.

Results

Grouped glands, aceto-white villi, and atypical vessels images had: prevalence of 21.3, 53.8, and 33.8% in patients with AIS, and 16.2, 19.5, and 9.3% in those with CIN 2 and 3; for the diagnosis of AIS, sensitivity of 21.3, 53.8, and 33.8%, specificity of 89.8, 95.2, and 94.9%, accuracy of 76.6, 87.2, and 83.1%, positive likelihood ratio of 2.1, 11.2, and 6.6, and AUC of 0.55, 0.74, and 0.64; for the diagnosis of CIN 2 and 3, sensitivity of 16.2, 19.5, and 9.3%, specificity of 89.8, 95.2, and 94.9%, accuracy of 39.4, 43.4, and 36.3%, positive likelihood ratio of 1.6, 4.1, and 1, 8, and AUC of 0.53, 0.57, and 0.52, respectively.

Conclusion

Prevalence and accuracy of the three images were higher for the diagnosis of glandular than squamous cervical precursor neoplasias. Sensitivity, specificity, positive likelihood, and AUC of aceto-white villi and atypical vessels images were higher for the diagnosis of glandular than squamous cervical precursor neoplasias.

Diagnostic value of the 2011 International Federation for Cervical Pathology and Colposcopy Terminology in predicting cervical lesions

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.

Explanation and Use of the Rio 2011 Colposcopy Nomenclature of the IFCPC (International Federation for Cervical Pathology and Colposcopy): Comments on the general colposcopic assessment of the uterine cervix: adequate/inadequate; squamocolumnar junction; transformation zone

In July 2012 the IFCPC adopted a revised terminology for colposcopic examinations of the uterine cervix. In 2012, the Boards of the Arbeitsgemeinschaft Kolposkopie (AGK - Austrian Society of Colposcopy), the Arbeitsgemeinschaft für Kolposkopie und Zervixpathologie (AGKOL - Swiss Society of Colposcopy and Cervical Pathology) and the Arbeitsgemeinschaft für Kolposkopie und Zervixpathologie (AGCPC - German Society of Colposcopy and Cervical Pathology) accepted the validity of the 2011 IFCPC nomenclature and recommended its use in general clinical practice across German-speaking countries. The revised nomenclature was devised so that examiners can evaluate colposcopic criteria according to a specific scheme. At the start of the examination, the examiner must assess whether the colposcopy is representative or not. 1. Can the examination be classed as adequate or inadequate (reasons must be given)? 2. How would you describe the visibility of the squamocolumnar junction and categorize the transformation zone? Below we discuss some aspects of this general assessment as outlined in the nomenclature which were found to require further clarification for general practice.

Colposcopy: a global perspective: introduction of the new IFCPC colposcopy terminology

This article describes the current nomenclature of colposcopic findings in the lower genital tract as defined by the International Federation for Cervical Pathology and Colposcopy (IFCPC) and agreed at their Triennial General Meeting in July 2012 in Rio de Janeiro. It builds on previous nomenclature published by the IFCPC over the last two decades and introduces for the first time the concept of transformation zone excision types. Vulval and vaginal colposcopic terminology is described.

Explanation and Use of the Colposcopy Terminology of the IFCPC (International Federation for Cervical Pathology and Colposcopy) Rio 2011

In July 2012 a revised terminology on colposcopic examinations of the cervix uteri was adopted by IFCPC. Central aspect is a description of characteristics that should aid in the definition of the disease entity cervix uteri. The nomenclature is built up in such a way that the examiner can evaluate colposcopic criteria according to a specific scheme. Firstly it is assessed whether the colposcopy is representative. Then it should be clarified whether or not the findings are normal. If the findings are not normal but rather abnormal the severity of the lesion is classified according to the so-called grade 1 (minor change) and grade 2 findings (major change). Specific abnormal findings such as leukoplakia, erosion and Lugol's finding are also not defined at this point. Characteristics suspicious for an invasion are described separately, in particular, atypical vessel patterns are mentioned here. As already held in the previous revised nomenclature (Barcelona), various findings are described in a last group: congenital transformation zones (CTZ), congenital anomalies, condylomas (papillomas), endometriosis, polyps (ectocervical, endocervical), inflammation, stenosis, postoperative changes (scarred portio, vaginal stump).

[Colposcopy in the diagnosis of early cervical cancer]

Cervical intraepithelial neoplasia and early cervical cancer are characterized by colposcopic minor and major changes and vessel abnormalities. In minor changes check-ups in most cases are sufficient. To avoid R1-resection and conization associated premature birth, conization should be performed under colposcopic visualization. In the USA and UK evidence based colposcopic guidelines were issued based on cytologic and colposcopic classifications. The German Society of Colposcopy (AG-CPC) published recommendations for the daily practice for all findings. For screening purposes there is no evidence to recommend colposcopy. In these cases, cytology is at the forefront, whereas colposcopy is only indicated in cases of conspicuous or unclear cytological results.
