Human Papilloma Virus (HPV) Circulating Tumor DNA (ctDNA) in Cervical Cancer

October 24, 2025 updated by: Mayo Clinic
This study collects blood samples to determine if the DNA of HPV that causes cervical cancer can be detected in patients with cervical cancer that is new (primary), has come back (recurrent), or has spread to other places in the body (metastatic) and are undergoing treatment with surgery, radiotherapy, chemotherapy, and/or immunotherapy. Researchers may use this information to predict response (good or bad) of the cervical cancer to treatment and detect recurrent cancer sooner.

Detailed Description

PRIMARY OBJECTIVES:

I. To estimate the ctDNA detection rate in cervix cancer patients undergoing surgery, radiotherapy, chemotherapy, and/or immunotherapy in the setting of primary, recurrent or metastatic disease.

II. Association of ctDNA baseline levels and clearance kinetics with clinical and radiographic tumor response.

III. To explore the association of detectable ctDNA at each time point with invasive recurrence-free survival and overall survival.

IV. To explore the use of ctDNA for surveillance and detection of disease recurrence.

V. To create a repository for future exploratory studies including analyzing changes in T cell and other immune cell subpopulations during and following therapy for cervix cancer.

OUTLINE: Patients are assigned to 1 of 4 cohorts.

COHORT 1: Patients undergo collection of blood samples at baseline prior to surgery, at 6 weeks, 3, 6, and 12 months post-surgery, every 6 months during year 2, and at the time of recurrence (if applicable).

COHORT 2: Patients undergo collection of blood samples at baseline prior to the first fraction of radiation, during week 4 of radiotherapy, at 6 weeks, 3, 6, and 12 months post-radiotherapy, every 6 months during year 2, and at the time of recurrence (if applicable).

COHORT 3: Patients undergo collection of blood samples at baseline prior to the first fraction of radiation, during week 4 of radiotherapy, on the day of the final fraction of radiotherapy, at 3 months post-radiotherapy, every 3 months during years 1 and 2, and at the time of recurrence (if applicable).

COHORT 4: Patients undergo collection of blood samples at baseline prior to initiation of chemotherapy or immunotherapy, at 4 weeks and 8 weeks after initiation of chemotherapy or immunotherapy, every 3 months during years 1 and 2, and at the time of recurrence (if applicable).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Proportion of patients with undetectable circulating tumor deoxyribonucleic acid (ctDNA) posttreatment in patients with detectable ctDNA pre-treatment
Time Frame: At 6 weeks post-surgery (cohort 1), at 4-6 weeks after completion of chemotherapy and radiation (cohort 2), 4-6 weeks post End of chemotherapy and radiotherapy (cohort 3), at 8 weeks after start of chemotherapy or immunotherapy (cohort 4)
The proportion will be reported along with the exact 95% binomial confidence interval. Additionally will report the mean standard deviation and median interquartile range ctDNA post-treatment in these patients.
At 6 weeks post-surgery (cohort 1), at 4-6 weeks after completion of chemotherapy and radiation (cohort 2), 4-6 weeks post End of chemotherapy and radiotherapy (cohort 3), at 8 weeks after start of chemotherapy or immunotherapy (cohort 4)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description

Time Frame: Baseline
Will be associated with Federation of Gynecology and Obstetrics stage and assessed using linear regression, reporting the correlation as well as the model estimates.
Baseline
Clinical tumor response
Time Frame: At post-treatment assessment, assessed up to 2 years
Will be assessed for association with baseline and post-treatment ctDNA using logistic regression. Depending on the number of tumor response, or non-response patients whichever is fewer, multiple variable models may be considered including additional relevant baseline covariates such as disease stage.
At post-treatment assessment, assessed up to 2 years
Radiographic tumor response
Time Frame: At post-treatment assessment, assessed up to 2 years
Will be assessed for association with baseline and post-treatment ctDNA using logistic regression.

Depending on the number of events, multiple variable models may be considered including additional relevant baseline covariates such as disease stage.
Up to 2 years
ctDNA clearance kinetics
Time Frame: Up to 2 years
Will be correlated with recurrence-free survival. ctDNA other than at baseline will be considered in these models as a time dependent covariate. Depending on the number of events, multiple variable models may be considered including additional relevant baseline covariates such as disease stage.
Up to 2 years
