Evaluation of the sensitivity of cervicography in a consecutive colposcopic series.

Cervicography was performed in 606 women referred for colposcopy. Cervigrams were blindly reviewed by two independent readers. The positivity rate at cervicography was high (operator A = 50%, B = 58.8%). The sensitivity for papillomavirus infection (HPV)/cervical intraepithelial neoplasia I (CIN I) (n = 141) was 79.4% for operator A and 80.8% for operator B. The sensitivity for CIN II or more severe lesions (n = 22) was 95.2% and 90.5% for operators A and B, respectively. The positive predictive value for HPV/CIN I or CIN II, or more severe lesions was 36.9% and 6.9% for operator A and 32.1% and 5.3% for operator B, respectively. Interobserver variability was acceptable (kappa = 0.62). Cervicography suspected 27 HPV/CIN I, 1 CIN II and 1 CIN III which showed no cytologic abnormalities. This study confirms that cervicography has a good sensitivity for cervical lesions, but it is based on a selected series, not representative of a screening condition. The combination of cervicography and cytology in screening is presently under evaluation in a prospective study of screened women.

Colposcopic diagnosis: clinical aspects and experiences.

Colposcopy can be applied as an integral part of every gynecologic examination in concert with cytology; to identify and localize lesions suspected on the basis of abnormal cytology findings; and to clarify the nature of clinically suspicious lesions. This implies using colposcopy to clarify the nature of cervical changes seen with the naked eye. This practice is superior to colposcopy which is restricted to evaluating abnormal smears because it can pick up some lesions missed by cytology. But it is not as effective as routine colposcopy because it can miss lesions not picked up by gross inspection of the cervix and because there is no opportunity to inspect the lower tract of the cervical canal. Considering that only 15-20% of lesions are purely endocervical, not too much time is wasted by examining these cases. If colposcopy is limited to evaluating grossly suspicious lesions, then its role is merely to avoid unnecessary biopsies.

Diagnostic reliability of prebioptic methods in the prediction of a histological basis of cervical lesions and its correlation with accuracy of colposcopically directed biopsy in patients with cervical neoplasia.

OBJECTIVE: High incidence of cervical cancer in the Czech Republic leads us to look for an optimal model of screening. The evaluation of the realiability of prebiopsy (cytology and colposcopy) and of punch biopsy is an important diagnostic step. MATERIAL AND METHODS: In a prospective study we examined 308 women detected by cytological screening who afterwards underwent surgery for a cervical lesion. Punch biopsy before the operation, most frequently by conization, was performed in every patient after assessing the prebioptic prediction (colposcopy and cytology). RESULTS: Reliable cytological screening associated with good colposcopy permits a correct diagnosis with high reliability. The rate of errors which increase the risk (threatening of health or the life of women) was 2.9% by prebioptic methods (high reliability) and 4.4% by punch biopsy. CONCLUSION: These good results are achieved in centers led by trained physicians and experts in cytology and skilled in colposcopy.
