Detection of Minimal Residual Disease Based on HPV ctDNA in Cervical Cancer

October 11, 2022 updated by: Peking Union Medical College Hospital

Clinical Value of Minimal Residual Disease Detection Based on Human Papillomavirus Circulating Tumor DNA (HPV ctDNA) in Cervical Cancer

In this study, a large-scale cohort of cervical cancer patients was established in multiple centers. Minimal residual disease(MRD) was assessed by ddPCR detection of HPV E7 gene ctDNA to assess tumor burden and predict the risk of disease recurrence, so as to provide new biomarkers for precise treatment of cervical cancer patients. The study continued until 36 months after the end of treatment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study is to assess MRD by detecting HPV E7 gene ctDNA to assess tumor burden and predict the risk of disease recurrence. According to the treatment methods, the patients were divided into two groups :(1) initial surgical treatment group (2) initial concurrent chemoradiotherapy group.

After the patients were enrolled in the study according to the criteria, they were given standard treatment. The patients were followed up every 3~6 months within 2 years after treatment and every 6~12 months from 3 to 5 years after treatment, including general and gynecological physical examination, cervical or vaginal cytology test, HPV typing test, SCC, CA125, and imaging examination such as CT or MRI if necessary.

Peripheral blood samples were collected to detect HPV E7 ctDNA before treatment, after treatment, and at 6, 12, 18, 24, 30, and 36 months of follow-up.

The primary endpoint is Disease-free survival (DFS, time from the treatment initiation to disease progression). Secondary endpoints include HPV ctDNA state before treatment, dynamic change trend of HPV ctDNA after treatment and overall survival (OS, time from the treatment initiation to death).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

initial surgical treatment group

After the patients were enrolled in the study according to the criteria, they were given standard treatment. The patients were followed up every 3~6 months within 2 years after treatment and every 6~12 months from 3 to 5 years after treatment, including general and gynecological physical examination, cervical or vaginal cytology test, HPV typing test, SCC, CA125, and imaging examination such as CT or MRI if necessary.

Peripheral blood samples were collected to detect HPV E7 ctDNA before treatment, 2 weeks after surgery, (1 month after adjuvent radiotherapy if available) and at 6, 12, 18, 24, 30, and 36 months of follow-up.
Other: detect HPV E7 ctDNA
Peripheral blood was collected from the patients, and the copy number of HPV E7 gene in ctDNA was accurately detected by ddPCR

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures
