Histologic findings after a colposcopic biopsy showing CIN2

Objective. To determine the risk of CIN3 and cancer in subsequent specimens among women with colposcopic biopsy showing CIN2. Methods. A retrospective review of demographic and medical information collected at colposcopy. Patient records were again reviewed 8 to 26 months later for information on procedures and histology results. Results. Histologic evaluation of specimens showed no lesions in 14, atypia or koilocytosis in 21, CIN1 in 25, CIN2 in 26, CIN 3 in 27, ungraded CIN in 3, and cancer in 3. No cancers were found in women at or below the median age of 33 years or those with satisfactory colposcopy. However, cancers were found in women with negative repeat cytology and negative colposcopic impression. Conclusion. Observation may be an option for young women with CIN2 on colposcopic biopsy if they are reliable for follow up and the entire squamocolumnar junction is seen.
