Objective: There is no other screening program close to the success rate of PAP test. Cervical cytology constitutes a large workload so that quality control in cervical cytology is important for the quality assurance of pathology laboratories. Material and Method: In this study, we collected the cervical cytology results from all over Turkey and discussed the parameters influencing the quality of the PAP test. The study was conducted with Turkish gynaecopathology working group and 38 centers (totally 45 hospitals) agreed to contribute from 24 different cities. The study was designed to cover the cervical cytology results during 2013. The results were evaluated from the data based on an online questionnaire. Results: The total number of Epithelial Cell Abnormality was 18,020 and the global Epithelial Cell Abnormality rate was 5.08% in the total 354,725 smears and ranging between 0.3% to 16.64% among centers. The Atypical squamous cells/Squamous intraepithelial lesion ratios changed within the range of 0.21-13.94 with an average of 2.61. When the centers were asked whether they performed quality assurance studies, only 14 out of 28 centers, which shared the information, had such a control study and some quality parameters were better in these centers. Conclusion: There is an increase in the global Epithelial Cell Abnormality rate and there are great differences among centers. Quality control studies including the Atypical squamous cells/Squamous intraepithelial lesion ratio are important. Corrective and preventive action according to quality control parameters is a must. A cervical cytology subspecialist in every center can be utopic but a dedicated pathologist in the center is certainly needed. [ABSTRACT FROM AUTHOR]

Objective: Cervical carcinoma has been included in the preventable diseases category ever since the use of cervical cytology in routine practice. The Pap test is an efficient screening test. We aimed to compare the cervical cytology diagnosis with biopsy and smear follow up results in our institution. Material and Method: We aimed to compare the diagnosis of cytology material examined in our institution during the 2009-2012 period with their biopsy and smear follow ups. The diagnoses were compared with the follow up smears and/or cervical biopsies. Results: 13610 Pap tests were examined during September 2009-July 2012. Among these cases, there were 370 atypical squamous cells of undetermined significance (ASCUS), 29 atypical squamous cells-high grade intraepithelial lesions cannot be excluded (ASC-H), 155 low grade squamous intraepithelial lesion (LSIL), 33 high grade squamous intraepithelial lesion (HSIL), and 5 atypical glandular cell (AGC) diagnoses. The ratio of atypical squamous cell (ASCUS and ASC-H) to squamous intraepithelial lesions was 2.12. Squamous intraepithelial lesion was verified in 47 of 91 ASCUS cases. Among patients who had a cervical biopsy, 52 of 64 LSIL cases and all of the 21 HSIL cases had biopsy-proven SIL. Conclusion: Atypical squamous cell (ASC) is the most common diagnosis in abnormal cervical cytology. As it is indefinite, ASC is used as a quality assurance parameter and the aim is to decrease its use. As the ratio of epithelial cell abnormality is variable in different populations, the ASC/SIL is a more definite variable to be used for quality assurance. The efficiency in clinical use of the cervical cytology screening test is determined by biopsy verification. Our epithelial cell abnormality, ASC/SIL ratio and cytology-histology correlation values were parallel to the literature, proving that the methods are used reliably at our institution.
