Establishing a Cervical Cytology Biorepository: A Protocol for Advancing Translational Cervical Cancer Research...

Area of Science:

• Gynecologic Oncology
• Molecular Epidemiology
• Biobanking

Background:

• Cervical cancer is a global health issue with screening disparities, especially in young US women.
• High-risk HPV is the main cause, but environmental factors need more study.
• The VCU Cervical Cytology Biorepository was created to research cervical cancer risk, biomarkers, and health disparities.

Purpose of the Study:

• To establish a cervical cytology biorepository using residual Pap specimens.
• To support research into the causes of cervical cancer and gynecologic health disparities.
• To enable multi-omic analyses for biomarker discovery.

Main Methods:

• Standardized protocols for recovery, processing, and storage of residual ThinPrep Pap specimens (ages 21-65).
• Utilized an opt-out consent model and IRB-approved waiver for discarded cytology.
• Integrated electronic health records for longitudinal clinical data and cryostored specimens at -80°C.

Main Results:

• The biorepository enables standardized processing of residual Pap specimens for genomic DNA extraction and metabolomic profiling.
• Pilot data confirm adequate input for multi-omic analyses from residual cervical cytology.
• Demonstrated feasibility and scalability of the biorepository protocol.

Conclusions:

• A framework for establishing a cervical cytology biobank from residual clinical specimens was developed.
• Linking biospecimens with clinical and demographic data facilitates research on cervical cancer and gynecologic conditions.
• This resource supports molecular epidemiology for biomarker identification and addressing reproductive health disparities.
