[Cytological screening of uterine cervical cancer by samples in liquid medium (CytoRich). Preliminary study of a series of 111 292 patients]. / Dépistage cytologique du cancer du col utérin par prélèvements en milieu liquide (CytoRich). Etude préliminaire d'une série de 111 292 patientes.

We report on the preliminary results of a series of 111,292 patients who benefited from a liquid medium sample (CytoRich) for cervical cancer screening. The number of dubious or limited smears was reduced by 0.03% and 0.53% respectively. The junction zone was better explored, and metaplastic changes were observed in 35.71% of the cases. This method improved the identification of low-grade lesions by +56% (2751/111,292; 2.47%) and of high-grade lesions by +75% (860/111,292; 0.77%), with a reduction in the number of ASCUS/AGUS by -44% (2065/111,292; 1.85%). This preliminary study confirms the results already published. The results demonstrating cytohistological correlation should prove to be a decisive factor, enabling the testing of the sensitivity and specificity of this technique. It will then be possible to envisage a future 'new paradigm' for screening cervical cancer as the result of a liquid medium sample, computer-assisted screening and HPV viral identification by Hybrid capture II.
