[Progress report on the Bethesda System].

The 2001 Bethesda System is a uniform system of terminology for reporting results of pap smears. It is acknowledged by most cytopathologists worldwide as a standard for cervical cytology reports. In France, several national surveys have confirmed its current utilization. However, more specific analysis have shown that the Bethesda System may be routinely modified by individual laboratories or even individual cytopathologist working within the same department. The aim of this progress report was to emphasize the importance of fully understanding the Bethesda System and applying it in a rigorous and standardized way.
