Application of Plasma Circulating HPV DNA Testing to Management of Cervical Intraepithelial Neoplasia

Completed
Conditions
Cervix Lesion
Cervical Cancer
Interventions
Diagnostic Test: digital PCR (dPCR) assay
Registration Number
NCT04274465
Lead Sponsor
UNC Lineberger Comprehensive Cancer Center
Brief Summary

The purpose of this study is to see if circulating HPV DNA (cHPVDNA) can be used as a noninvasive biomarker for cervical intraepithelial neoplasia (CIN) 2-3 in hopes of reducing procedures and costs for patients, as well as personalize their treatment plan.

Detailed Description

cHPVDNA is detectable in plasma of patients with invasive disease and CIN 1-3, and with the development of a highly sensitive and specific droplet digital Polymerase Chain Reaction (PCR) assay, it is hoped to be identified more prevalently and thus can improve risk stratification and help produce personalized treatment decisions and may be more cost-efficient. Plasma samples and cervical swabs will be collected from patients in University of North Carolina (UNC) Gynecology clinics, and some patients will also provide a urine sample. Those receiving biopsies or colposcopies and will come back to clinic 2-4 weeks post-excision for collection of another blood specimen. Using plasma samples and pathology results, we will characterize the relationship between plasma cHPVDNA levels and 1) CIN 1 versus CIN 2-3 pathology 2) CIN 2-3 pre-excision and 2-4 weeks post-excision. We will accrue three cohorts of 25, 30, 30 patients corresponding to 1) Control 2) CIN 1 3) CIN 2-3. The control cohort will establish background signal in the assay. We will compare the proportion of detectable cHPVDNA levels between CIN 1 and CIN 2-3 cohorts using Fisher's exact test with 80% power, significance level of 10%. Paired t-test will be used to compare pre- and post-excision cHPVDNA levels.

Primary Outcome Measures
NameTimeMethod
Relationship between plasma cHPVDNA levels and presence of CIN 2-3 histopathologyBaseline

We will quantify cHPVDNA levels in blood plasma from patients with normal screening, CIN 1, and CIN 2-3 cervical disease prior to treatment.

Secondary Outcome Measures
NameTimeMethod
Changes in cHPVDNA levels following excisional therapy for CIN 2-3 cervical disease.2-4 weeks post-excision

For patients who undergo excisional therapy, we will collect bio-specimens and quantify cHPVDNA levels in plasma during their post-procedure visit.
