Cytological reporting of cervical abnormalities according to endocervical status.

An analysis of cytology reporting within Victorian Cytology Service demonstrates that the proportion of Papanicolaou smears which were reported as including an endocervical component increased from approximately one half during 1987-89 to more than three quarters during 1990-91. The improvement coincided with the routine provision of special sampling instruments to all practitioners supplemented by an education program. Despite the increase in endocervical sampling, no increase in the rate of reporting of high-grade intraepithelial lesions of the cervix has occurred. An increase between the two time periods in the cytological reporting of adenocarcinoma, adenocarcinoma in situ and endocervical dyskaryosis has occurred, but does not reach statistical significance.
