Aim. To investigate the agreement between cervical cytology assessed by conventional hematoxylin-eosin staining and liquid-based cervical cytology (BD SurePath™ liquid-based Pap test).
Materials and methods. The study analyzed cervical cytology diagnoses of 2426 women aged 19 to 68 (mean
34 ± 11) who sought obstetric and gynecology care between 2018 and 2019 and underwent liquid-based cervical cytology using BD SurePath™ liquid-based Pap test and cervical cytology assessed by conventional hematoxylin-eosin staining.
Results. Liquid-based cervical cytology was associated with significantly higher detection rate of cervical intraepithelial neoplasia of various grades (LSIL + HSIL) compared to conventional cervical cytology (15.13 ± 0.4% and 11.99 ± 0.2%, respectively, p = 0.016 ); it also better characterized the inflammatory process (28.7 ± 1.3% and 17.9 ± 1.2%, respectively, p = 0.042) and dysbiosis (5.7 ± 0.2% and 9.3 ± 0.3%, respectively, p = 0.015) in endocervical samples, which is necessary for an adequate diagnosis and perioperative treatment of patients to prevent the recurrence of cervical neoplasia.
Conclusion. The findings of the study suggest an advantage of liquid-based cervical cytology over conventional technique, which allows a recommendation to use liquid-based cytology as the preferable cervical screening modality.
