Positive cervical smear with subsequent normal colposcopy and histology--frequency of CIN in a long-term follow-up.
From a total of 1466 new cases of cervical smears suggesting cervical intraepithelial neoplasia (CIN) II or worse, all examined with colposcopy and biopsies, 328 cases (22.4%) were initially examined with vaginal and cervical colposcopy, directed biopsies of portio, and endocervical curettage (ECC) with normal results. Patients were followed-up with regular colposcopy and cervical smear for an average of 10.6 years (2-19 years). In 72 cases (22%) a CIN occurred, in general more than 1 year (mean 2.96 years) after entering the study. Possible explanations are discussed and careful monitoring of this group of patients is recommended.
