The application of liquid biopsy techniques in cervical cancer diagnosis, prediction and therapeutic surveillance

Cervical cancer (CC) is a significant cause of cancer-related deaths in women and ranks as the fourth most common malignant tumor worldwide. Cervical histopathology is currently the primary diagnostic method for confirming the presence of CC. Tumor markers and imaging techniques play crucial roles in monitoring treatment effectiveness and prognostic follow-up. Unfortunately, these traditional examination methods are invasive and often lack sensitivity and accuracy. Therefore, there is a need for a less invasive and more sensitive test to facilitate early diagnosis, efficacy evaluation, and prognostic monitoring of CC. In recent years, liquid biopsy has been developed as a new detection method. It involves analyzing tumor components released into the peripheral circulation, such as cell-free RNA, circulating tumor DNA, circulating tumor cells, tumor-educated platelets, and exosomes. Liquid biopsy offers advantages such as being less invasive, highly reproducible, and capable of real-time monitoring. Moreover, liquid biopsy can play a crucial role in the early diagnosis of CC, guiding targeted therapy, assessing prognosis, and evaluating treatment effectiveness. This review focuses on the value of liquid biopsy application in CC, detection markers, and detection methods. It also explores how liquid biopsy can be used in the detection, prognosis, and monitoring the progression of CC. The advantages and limitations of liquid biopsy in CC are analyzed to promote its application and improve the diagnosis and treatment of the disease.
