A Comparative Study of Conventional Pap Smear and Liquid-Based Cytology

Area of Science:

• Gynecology
• Oncology
• Cytopathology

Background:

• Cervical cancer poses a significant global health challenge, particularly in developing nations.
• Georgia faces a high burden, with it being a leading cause of cancer death among women.
• Effective screening is vital for reducing cervical cancer incidence and mortality.

Purpose of the Study:

• To compare the efficacy of liquid-based cytology (LBC) against conventional Pap smears for cervical cancer screening in Georgia.
• To evaluate differences in sample adequacy and detection rates between the two methods.

Main Methods:

• Analysis of 1000 cervical cytology samples from asymptomatic women aged 18-65 in Georgia.
• Samples processed using ThinPrep technology and stained via the Papanicolaou protocol.
• Reporting followed the Bethesda 2001 System, with evaluation by light microscopy.

Main Results:

• Liquid-based cytology (LBC) demonstrated significantly higher rates of satisfactory smears (89.4% vs. 80.3%) and lower unsatisfactory rates (1.33% vs. 7.33%) compared to conventional Pap smears.
• LBC showed improved detection rates for various squamous intraepithelial lesions, including NILM, ASCUS, ASC-H, LSIL, and HSIL.
• These findings indicate superior diagnostic accuracy with LBC.

Conclusions:

• Liquid-based cytology (LBC) is a more effective screening method than conventional Pap smears for cervical cancer.
• Wider implementation of LBC in Georgia can enhance early detection and reduce disease burden.
• LBC's superior performance supports its adoption in clinical practice for improved patient outcomes.
