摘要

Background

Cervical cancer is the second most common cancer worldwide, with three-fourths of cases occurring in developing countries. In India, it is the most prevalent genital malignancy among women. Despite advances in screening, early detection, and treatment, recurrence remains a common occurrence. Liquid-based cytology (LBC) helps to reduce the rate of inadequate samples and increase screening capacity, which has been successfully achieved. Additionally, some of the extra costs associated with liquid-based cytology have been balanced by a reduction in repeat tests.

Methods

A narrative review of current literature was undertaken to assess the diagnostic performance, technical advantages, and clinical applications of liquid-based cytology compared with conventional cytology techniques.

Results

Liquid-based cytology is a thin-layer or monolayer slide preparation technique designed to enhance the sensitivity and specificity of cytologic assessment. It has become a preferred method over conventional smear and cytospin techniques, demonstrating equal or superior diagnostic accuracy, especially in specimens with abundant mucus or blood. Additionally, liquid-based cytology is better suited for immunocytochemistry and further analyses, including molecular investigations. This method also provides a foundation for human papillomavirus testing, automation, and emerging technologies, like advanced flow cytometry, confocal microscopy, and HPV methylation markers. These new techniques are also useful in the prognosis of patients, guiding further treatment. Women benefit from quicker results and reduced anxiety.

Conclusion

Liquid-based cytology is superior to conventional cytology, but not solely due to its sensitivity. Other factors contribute to its advantage, and the incorporation of automation may further enhance its effectiveness. As current research focuses on developing combined strategies with novel tests to improve sensitivity and specificity in triaging patients with positive HR-HPV types, liquid-based cytology could be the best option.
