DNA Methylation Biomarkers to Predict Survival After Surgery for Lung Adenocarcinoma

June 5, 2025 updated by: Chen Qihan, Nanjing University

A Multicenter Retrospective Study Identifying DNA 5mC Predictors for LUAD Prognosis

This study is designed to assess DNA 5-methylcytosine (5mC) methylation modifications in lung adenocarcinoma (LUAD) samples and develop a prognosis-predictive model for LUAD based on cancer tissue DNA 5mC levels. The research will link post-surgical recurrence and survival outcomes to the DNA 5mC profiles of patients. By collaborating with two hospitals in China, this multicentral study will utilize over three years of prognostic data from LUAD patients to validate the model's accuracy. Additionally, the research aims to explore the potential of the model in guiding adjuvant treatment strategies by comparing the differences in outcomes between high-risk patients who receive further treatment and those who do not. This study aspires to enhance future treatment planning for LUAD patients, providing personalized and effective therapeutic options based on precise prognostic predictions.

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.

Detailed Description

  • Model Development

    • The methylation data will be analyzed to identify specific 5mC methylation patterns associated with post-surgical recurrence and survival outcomes.
    • A prognostic model will be developed based on these methylation profiles to predict LUAD prognosis.

  • Model Validation

    • Clinical data from LUAD patients at two hospitals in China, including over three years of follow-up information, will be used to validate the accuracy and reliability of the prognostic model.
    • Statistical methods will be applied to assess the model's predictive power and its ability to accurately stratify patients into different risk categories.

  • Exploration of Follow-up and Adjuvant Therapy Guidance

    • The study will compare outcomes between high-risk patients who receive additional adjuvant treatment and those who do not, based on the risk categories identified by the prognostic model.
    • This comparison aims to explore the model's potential in guiding adjuvant therapy decisions, ultimately enhancing personalized treatment strategies and improving survival rates for LUAD patients.

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.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.

LUAD patients who received surgical treatment and were followed up at Nanjing Drum Tower Hospital

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
Overall survival
Time Frame: 4years and/or 5years after surgery completion
Subjects will be divided into high-risk and low-risk groups based on the DNA methylation model. The overall survival (OS) of these two groups will be compared to determine if there is a significant difference. Additionally, we will analyze whether there are significant differences in OS between high-risk and low-risk groups that received further treatment and those that did not.
4years and/or 5years after surgery completion

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
Disease-free survival
Time Frame: 4-year and/or 5-year after surgery completion
Subjects will be divided into high-risk and low-risk groups based on the DNA methylation model. The disease-free survival (DFS) of these two groups will be compared to determine if there is a significant difference. Additionally, we will analyze whether there are significant differences in DFS between high-risk and low-risk groups that received further treatment and those that did not.
