Self-Sampling Modality for Cervical Cancer Screening: Overview of the Diagnostic Approaches and Sampling Devices

Abstract

Cervical cancer remains the fourth most common malignancy among women worldwide. Despite well-developed prevention measures, incidence and mortality continue to rise, especially in low- and middle-income countries due to low screening coverage and unavailability of human papillomavirus (HPV) vaccination. The cervical cancer screening coverage could be improved by the implementation of a self-sampling modality for HPV testing. Multiple research pieces support the validity and reliability of a self-sampling modality as an alternative approach to clinician-collected samples for primary cervical cancer screening via HPV genotyping. Moreover, growing research evidence on the self-sampling modality reception shows high acceptance of the method among screened populations. Studies on the self-sampling approach economic efficiency also revealed a high cost-effectiveness of HPV testing through a self-sampling modality compared to other screening modalities for cervical cancer. It is specifically important for low-resource settings, which should use the self-sampling cost advantages to improve cervical cancer screening coverage by attracting underscreened populations. Overall, self-sampling modality has a higher participation rate and better patient satisfaction reported; thus, the method is highly recommended by the World Health Organization for cervical cancer screening.
