November 29, 2023 updated by: Xian-Jun Yu, Fudan University

Explorations of Cell-free DNA Multi-omics Technology in Detection of Minimal Residual Disease and Disease Prognosis After Surgery in Early Pancreatic Ductal Adenocarcinoma: A Single-center, Prospective, Observational Case Study

This trial aims to develop a minimal residual disease (MRD) detection model for predicting recurrence of patients with stage I-II pancreatic ductal adenocarcinoma after surgery and adjuvant therapy, based on cfDNA fragmentation and methylation signal.

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 entire study is divided into two stages. Stage one is the enrollment period. 51 subjects with pancreatic ductal adenocarcinoma in stages I-II who have not received neoadjuvant therapy and have undergone radical surgery were enrolled. Blood samples at the time point before surgical treatment (T0) were collected and fresh tissue specimens (cancerous tissue and adjacent normal tissue) were collected. Blood samples were subjected to methylation, fragment group, and CNV multi-omics testing, and tissue samples were subjected to target methylation area testing. Stage two is the follow-up period. Blood samples from the fifth week after surgery to before adjuvant therapy (T1) and blood samples from 4-8 weeks after adjuvant therapy (T2) were collected. Blood samples were subjected to methylation, fragment group, and CNV multi-omics testing with different techniques. The subjects were followed up for 1.5 years. According to progression and recurrence, the subjects were divided into progression group and non-progression group. Methylation and multi-omics prognosis models were trained and compared for their performance in residual detection and recurrence prediction.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample
