Is this the end of the line for the moderate dyskaryotic smear?
OBJECTIVE
The British Society for Clinical Cytology has recently proposed that the terminology for cervical smear reporting is to be changed from a 3-tier system (mild, moderate, severe dyskaryosis) to a 2-tier system of low-grade and high-grade dyskaryosis. This modification eliminates the central category of moderate dyskaryosis which would be incorporated into the high-grade group. The aim of this study was to investigate the role of the moderate dyskaryotic smear in clinical practice.


METHODS
A retrospective review of all women who were referred for colposcopy because of a moderate dyskaryotic smear was carried out for a 6-month period. Data collected included colposcopic impression, procedure performed and final histopathology. Two cytologists who were unaware of the original smear report were asked to reclassify these smears using the new 2-tier system. Their findings were compared with the documented colposcopic and histopathology results.


RESULTS
One hundred women with moderate dyskaryotic smears were referred for colposcopy during the study period. Most of these were reclassified as high-grade dyskaryosis using the new system. Fifty-six (72%) of the moderate dyskaryotic smears which were correctly regraded as high grade by cytologist 1 were found to have cervical intraepithelial neoplasia 2/3 on final histopathology, whereas for cytologist 2, 66 (68%) were found to have high-grade cervical intraepithelial neoplasia.


CONCLUSIONS
There is no clinical benefit in retaining the term moderate dyskaryosis. This study emphasizes the need for a uniform 2-tier system.
