Consistent Condom Use Increases the Regression Rate of Cervical Intraepithelial Neoplasia 2-3

Cervical intraepithelial neoplasia grades 2-3 (CIN2-3) are usually treated by cone excision, although only 30% progress to cancer and 6-50% regress spontaneously. The aim of this study was to examine the influence of clinical factors like smoking habits, number of lifetime sexual partners, age at first sexual intercourse, sexual activity span and hormonal versus non-hormonal contraception type on the regression rate of CIN2-3.In this prospective population-based cohort study 170 women aged 25-40 with abnormal cytology and colposcopy-directed biopsies showing first time onset CIN2-3 were consecutively included. The interval between biopsy and cone excision was standardized to minimum 12 weeks. Regression was defined as ≤ CIN1 in the cone biopsy.The regression rate was 22%. Consistent condom use, defined as those women whose partners used condoms for all instances of sexual intercourse, was infrequent (n=20, 12%). In univariate analysis consistent condom use, hormonal contraception and age at first sexual intercourse significantly predicted regression. In a multivariate analysis only consistent condom use remained as an independent predictor of regression (regression rate 55%, p=0.001, hazard ratio=4.4).Consistent condom use between punch biopsy and cone excision in first-time onset CIN2-3 patients significantly increases the regression rate

Computerised morphometrical analysis in endometrial hyperplasia for the prediction of cancer development. A long term retrospective study from northern Norway

Aims—To evaluate and compare the long term prognostic value of the WHO classification and the computerised multivariate morphometrical D score in endometrial hyperplasia. To test the reproducibility of the D score in two different centres. Methods—Histopathological WHO classification and computerised morphometrical analysis using the D score (< 0, high risk; > 1, low risk; 0–1, uncertain) in a population based study from northern Norway of archival dilatation and curettage material from 68 women with 10–20 years of follow up. Results—Of the 68 patients included in the study, 18 developed cancer. The sensitivity and specificity of the D score (< 0 v > 1) were 100% and 78%, respectively, which was better than the WHO classification (89% and 60%, respectively). The negative and positive predictive values for the D score were 100% and 58% and of the WHO classification 94% and 44%, respectively. This study found a slightly higher specificity for the D score than former retrospective studies, but otherwise the results were comparable. The D score results were reproducible between the two centres (R = 0.91; slope = 0.98; intercept = 0.3). Conclusions—D score assessment is a reproducible and more accurate predictor of outcome of endometrial hyperplasia than the WHO classification assessed by an experienced gynaecological pathologist. Routine application of the D score might reduce over and undertreatment of endometrial hyperplasia. Key Words: endometrial hyperplasia • cancer • image analysis • prognostic classification rul
