Cytohistological correlation and discrepancy of conventional Papanicolaou smear test with corresponding histopathology: a retrospective study over a 5-year period.

The accuracy of Papanicolaou (Pap) smear testing can be measured using the cytohistological correlation and discrepancy method. This study aimed to evaluate and compare the cytohistological correlation and discrepancy of the conventional Pap test with the corresponding histopathology and to compare the data with other similar studies. A retrospective study was performed at the pathology department of a referral hospital in Muscat, Oman, over a 5-year period. Of 6000 Pap smears, 162 had matching histopathology results (abnormal smear rate 2.7%) but 10 were unsatisfactory for histological diagnosis. Cytohistological correlation was seen in 96/152 (63.2%), while discrepancy was seen in 56/152 (36.8%). False negatives and false positives were found for 7 and 49 cases respectively. The findings of this study confirm the role of conventional Pap testing as a screening test for the diagnosis of cervical lesion but not for management of patients. In comparison with other studies, we also report a low percentage of abnormal Pap smears.

L'exactitude du test de Papanicolaou classique peut être mesurée à l'aide de la méthode de la corrélation et de la discordance cytohistologiques. La présente étude visait à évaluer et à comparer la corrélation et la discordance cythohistologiques du test de Papanicolaou classique à l'histopathologie correspondante et à comparer les données à celles d'autres études similaires. Une étude rétrospective a été menée dans le service de pathologie d'un hôpital de recours à Mascate [Oman], sur une période de cinq ans. Sur un total de 6000 frottis vaginaux, 162 présentaient des résultats histopathologiques concordants [taux de frottis anormaux : 2,7 %] mais 10 d'entre eux n'étaient pas satisfaisants pour le diagnostic histologique. Une corrélation cytohistologique a été observée dans 96/152 des cas [63,2 %], tandis qu'une discordance a été observée pour 56/152 cas [36,8 %]. Des faux négatifs et des faux positifs ont été observés dans 7 cas et 49 cas, respectivement. Les résultats de cette étude confirment le rôle du test de Papanicolaou classique en tant que test de dépistage pour le diagnostic d'une lésion cervicale mais pas pour la prise en charge des patientes. Par rapport à d'autres études, nous avons aussi observé un faible pourcentage de frottis vaginaux anormaux
