Objective: To evaluate the interobserver reliability of colposcopy and the prediction of final histologic results.Materials and Methods: Visibility of the squamocolumnar junction, presence and grading of atypical transformation zone (ATZ), and presence and grading of cervical intraepithelial neoplasia (CIN) were assessed by nine expert colposcopists in 100 cervigrams. Pairwise kappa, group kappa, and class-specific kappa values were computed. Frequency and degree of interobserver disagreement on CIN and ATZ grading and correlation with histologic results were studied.Results: The median pairwise kappa and the group kappa values were excellent for ATZ detection, acceptable for the squamocolumnar junction, and poor for the other variables; the presence of ATZ had a sensitivity for CIN of 90.2% and a specificity of 48.6%; the colposcopic impression of high-grade CIN had a sensitivity of 54.4% and a specificity of 88%.Conclusions: Some colposcopic predictions are reproducible between observers, predictive of the histologic results, and can be integrated in the algorithm for the management of patients with abnormal Pap smear results.

Abstract: Vulvar examination during procedures for cervical carcinoma screening (CCS) can be a valid chance for early diagnosis of vulvar diseases and precancerous lesions. With this aim an online questionnaire was sent to the members of the Italian Cervical Carcinoma Screening Group (GISCi) from either first level group (FLG, Pap/human papillomavirus test sampling) or second level group (SLG, colposcopy and treatments) to assess if and how vulvar examination was performed. 86% of FLG and 90.2% of SLG report performing vulvar examination prior to CCS procedures. 15% of SLG cannot manage basic vulvar diseases and they refer patients to specialized center. 54.3% underline lack of standardized protocol in case of vulvar disease detection. Despite most health care professionals report examining the vulva during CCS procedures, vulvar cancer early diagnosis is still challenging., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2024, ASCCP.)

Objective: To report the results of an Internet-based colposcopy quality assurance program from a population-based cervical screening service in a large region of northern Italy., Methods: In 2010 to 2011, a Web application was made accessible on the Web site of the regional administration. Fifty-nine colposcopists of the registered 65 participated. They logged-in, viewed a posted set of 50 high-quality digital colpophotographs selected by an expert committee, and rated them for colposcopic impression using a 4-tier classification (Negative; abnormal, grade 1 [G1]; abnormal, grade 2 [G2]; suspected invasive cancer [Cancer]) derived from the International Federation for Cervical Pathology and Colposcopy 2002 classification. kappa (κ) coefficients for intercolposcopist agreement and colposcopist-committee agreement were calculated., Results: Colposcopist-committee agreement was greater than intercolposcopist agreement (overall κ 0.69 vs 0.60, p<.001). The κ values for colposcopist-committee agreement were 0.83 on Negative, 0.53 on G1, 0.66 on G2, and 0.80 on Cancer (all p values for pairwise comparisons<.001, except for Negative vs Cancer [p=.078]). There was no systematic tendency for colposcopists to underestimate or overestimate the colposcopic findings (2-tailed sign test, p=.13). Overall colposcopist-committee agreement was greater among patients 35 years or older (p<.001) and for colposcopists with previous quality assurance experiences (p<.01). Only 0.2% of Negative impressions were formulated for a cervical intraepithelial neoplasia grade 2 or worse. As a parallel finding, the impression of Cancer predicted cervical intraepithelial neoplasia grade 2 or less in 0.5% of cases. The histologic substrates of G1 were dispersed over a large spectrum., Conclusions: The reproducibility of colposcopic impression, when classified by trained colposcopists examining high-quality images, is higher than is generally thought.

Objective: To evaluate the effectiveness of microcolposcopy in preventing incomplete electrosurgical excision at the endocervical cone margin in patients with CIN and unsatisfactory colposcopy., Materials and Methods: Four-hundred and twenty-one patients were studied. Complete excision of disease at the endocervical margin was evaluated using multiple logistic regression analysis., Results: One-hundred and eighty-three patients underwent microcolposcopy. In 160 patients, the cone depth exceeded the endocervical extension of the squamocolumnar junction as predicted by microcolposcopy. In 23 patients, the opposite was observed. Microcolposcopy was not performed in 238 patients. For the three groups, the frequency of endocervical cone margin involvement was 22%, 22%, and 13%, respectively. Multiple logistic regression analysis showed that patients with a cone depth exceeding the endocervical margin of the squamocolumnar junction as predicted by microcolposcopy had no reduction in the risk of incomplete conization., Conclusion: The use of microcolposcopy awaits validation for assessment of the transformation zone to predict negative conization margins.
