About this study

Official title: A Prospective Study of Circulating Tumor DNA Detection by Targeted Sequencing in Surgical Non-Small Cell Lung Cancer Patients

Conduct a prospective study to compare gene detection by ctDNA with tumor tissue DNA via targeted DNA sequencing in surgical NSCLC patients.

Read the detailed description

Previous studies have shown the feasibility of detecting mutation status by circulating tumor DNA (ctDNA)in non-small cell lung cancer (NSCLC) patients. However, no clinical standard method has been established, and most previous studies were lack of prospective clinical data and aimed at advanced NSCLC.

We plan to perform a prospective study including consecutive cases of NSCLC patients who underwent surgical treatments. Primary tumor and plasma samples were collected in each patients and gene mutation analysis were performed immediately after surgery. We utilized the targeted DNA sequencing with a next-generation sequencing (NGS) platform to detect driver somatic mutations in matched tumor DNA (tDNA) and plasma ctDNA samples with matched white blood cell (WBC) DNA as a control. A panel of genes were identified.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Whether ctDNA can detect genomic alterations in peripheral blood that are consistent with those in matched tumor sample

    Measured: 2-3 months

Secondary outcomes (4)
  1. Concordance of tDNA and plasma ctDNA gene detection in early stage non-small cell lung cancer

    Measured: 2-3months

  2. Correlation of ctDNA concentration with clinical features

    Measured: 2-3months

  3. Comparison of positive predictive value between ctDNA and tumor markers

    Measured: 2-3months

  4. The relationship between ctDNA concentration and disease free survival(DFS)

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Carcinoma, Non-Small-Cell Lung, run by Peking University People's Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Whether ctDNA can detect genomic alterations in peripheral blood that are consistent with those in matched tumor sample (time frame: 2-3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jan 2016.
