About this study

Official title: Feasibility of Targeted Bronchial Washing Fluid for Molecular Testing With Next Generation Sequencing in Patients With Early-stage Non-small Cell Lung Cancer

This is a single center, clinical trial evaluating the relevance of intratumoral washing for detection of generic alteration with Next Generation Sequencing.

Read the detailed description

This is a prospective, single-arm, open-label study to assess evaluate the relevance of intratumoral washing by ultrathin bronchoscopy (outer diameter; 3mm) for detection of genetic alterations using Next Generation Sequencing in patients suspicious of early-stage lung cancer.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ultarthin bronchoscopy with intratumoral washingDiagnostic test

    Each subject suspected of early-stage, resectable lung cancer will undergo bronchooscopic procedure. Ultrathin bronchoscope is inserted and placed within tumor under radial EBUS, virtual bronchoscopic navigation, and fluoroscopy guidance. Subsequently, intratumoral washing is performed. After undergoing surgery for suspected early-stage lung cancer, the analysis of next generation sequencing is conducted on intratumoral washing, tissue from surgical specimen, and blood.

What is being measured

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

  1. The diagnostic accuracy of genetic alterations in intratumoral washing fluid using Next Generation Sequencing

    Diagnostic accuracy is defined as the number of true positive and true negative genetic alterations detected by Next Generation Sequencing, divided by the total number of intratumoral washing attempts using ultrathin bronchoscopy.

    Measured: through study completion, an average of 1 year

Secondary outcomes (5)
  1. Detection rate of clinically significant actionable mutations among intratumoral washing fluid, plasma, and tissue

    Detection rate is defined as the number of genetic alterations detected by Next Generation Sequencing divided by the total number of intratumoral washing attempts using ultrathin bronchoscopy. Clinically significant actionable mutations are defined as genes with corresponding drugs, either approved or under clinical trial (e.g., EGFR, ALK, ROS1, BRAF V600E, RET, NTRK, KRAS G12C, FGFR3, or HER2).

    Measured: through study completion, an average of 1 year

  2. Concordance rate of genetic alterations detected by Next Generation Sequencing among intratumoral washing fluid, plasma, and tissue

    The concordance rate of genetic alterations detected by Next Generation Sequencing in intratumoral washing fluid, compared with plasma and tissue (gold standard).

    Measured: through study completion, an average of 1 year

  3. Sensitivity and specificity of genetic alterations detected by Next Generation Sequencing in intratumoral washing fluid

    The sensitivity and specificity of genetic alterations detected by Next Generation Sequencing in intratumoral washing fluid compared with tissue (gold standard).

    Measured: through study completion, an average of 1 year

  4. Turn-around time

    The duration between an order request and the task completion in in intratumoral washing fluid compared with plasma and tissue (gold standard).

    Measured: through study completion, an average of 1 year

  5. Detection rate of co-mutations among intratumoral washing fluid, plasma, and tissue

    Detection rate is defined as the number of genetic alterations detected by Next Generation Sequencing divided by the total number of intratumoral washing attempts using ultrathin bronchoscopy. Co-mutations are defined as the occurrence of two or more genetic alterations within the same tumor cells in an individual, including at least one actionable mutation (e.g., TP53, DNMT3A, TET2, CTNNB1, PIK3CA, RB1, STK11).

    Measured: through study completion, an average of 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Ultarthin bronchoscopy with intratumoral washing in people with Lung Cancer, run by Pusan National University Hospital at 1 site in South Korea.

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

Who may be eligible to take part?

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: under way, not looking for participants, as of the sponsor's last update on 11 Mar 2026. 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 South Korea. 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?

This study is still under way. Results are not available in the source record yet.

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?

The diagnostic accuracy of genetic alterations in intratumoral washing fluid using Next Generation Sequencing (time frame: through study completion, an average of 1 year). 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 11 Mar 2026.
