Abstract: | The terminology used for reporting cervical samples in the UK is the BSCC classification, which has evolved over many years. In 2002 the BSCC held a consensus conference to review the BSCC classification, with the intention of providing clearer results for women, improving concordance with other terminologies and facilitating consistency with new scientific developments and technologies. The consensus conference was well attended and robust. In the intervening years there have also been other further advances on morphometry, data on outcomes, data from EQA and other sources. Liquid Based cytology (LBC) has been implemented by the NHS CSP. All of these developments have impacted on the proposed classification, which will be presented in full. The term 'dyskaryosis' will be retained and several of the current reporting categories will be relatively unchanged, though additional information on LBC will be provided. The major proposed changes are: (1) A move to a single category of 'High Grade Dyskaryosis' to replace the existing categories of moderate and severe dyskaryosis. (2) Sub-division of Borderline change into three categories. Borderline change in glandular cells Borderline change ?high grade Borderline change, NOS (3) The current grades of Mild Dyskaryosis and Borderline change with Koilocytosis to be merged. Details of these proposals, together with illustrations and the evidence base for change will be presented. |
