ABSTRACT
We compared the diagnostic accuracy of liquid-based cervicovaginal cytology using MonoPrep2(TM) system (Monogen, Herndon, Virginia, USA), a manual system based on membrane filtration method, with conventional Pap smear. Study population included 92 patients visiting the gynecologic department under the suspicion of uterine cervical disease. In thirty of them, surgical biopsy was performed. MonoPrep2(TM) system provided well-preserved monolayer specimen with good nuclear morphology. However, about 19% of specimens were inadequate to interpret due to low cellularity. The detection rate of abnormal cells more than ASCUS (atypical squamous cells of unknown significance) was 23.9% and higher than 19.4 % of conventional Pap smear. Diagnostic concordance rate with conventional Pap smear was 81%, and severe discordance rate influencing on the management of patient was 7.6 %. Among these seven cases, MonoPrep2(TM) system was more diagnostic only in four. In comparison with histology, the sensitivity of diagnosis of MonoPrep2(TM) system was 78.9% and slightly higher than 73.5% of conventional Pap smear. However, the specificity was 81.1% and lower than 90.9% of Pap smear. In conclusion, MonoPrep2(TM) system provided diagnostic accuracies similar to the conventional Pap smear. The inexpertness of slide preparation and the low cellularity were considered to endow a limitation in more accurate evaluation.
