Abstract

Objective To determine the accuracy of colposcopic and cytological assessment at predicting final histological diagnosis in women referred with abnormal cervical smears during pregnancy; to use this data as a basis for a follow up protocol for pregnant patients referred with abnormal cervical cytology. Study design Retrospective analysis of women referred to Queens Medical Centre, Nottingham, UK with abnormal cytology whilst pregnant between 1994 and 2003. Results Forty-nine patients in total were included in the study. Colposcopic assessment in the antenatal period had a concordance with final histological diagnosis in 60% of patients and a concordance of 68% when undertaken in the post-natal period. Cytological concordance was lower at 58%. In only six percent of patients was a cervical biopsy undertaken and there were no complications as a result. There was a fall in colposcopically assessed high-grade cervical intraepithelial neoplasia between the antenatal and post-natal period. No cases of invasive cancers were diagnosed antenatally. Conclusion A policy of conservative management of pregnant patients during the antenatal period is supported by this data. A suggested protocol of one colposcopic assessment at the time of the index abnormal smear followed by a post-partum colposcopy, and appropriate treatment is suggested.
