Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age ≥ 18 years;
  • At least 1 hilar/mediastinal lesion (short axis ≥ 1 cm) requiring diagnostic bronchoscopy procedure;
  • Patients who can understand the purpose of the trial, participate voluntarily and sign an informed consent form.

Who cannot join

  • The lesion is a mediastinal cyst or abscess;
  • Combined severe cardiopulmonary diseases, coagulation disorders, poor tolerance to anaesthesia, combined psychiatric disorders or severe neurosis and other relevant contraindications to bronchoscopy;
  • EBUS assessment reveals that the lesion is rich in blood flow or adjacent to a large vessel, etc. Consider biopsy to be high risk and inappropriate for continuation of biopsy;

About this study

Official title: The Comparison of Endobronchial Ultrasound-guided Transbronchial Needle Aspiration, Mediastinal Cryobiopsy Via a Tunnel, and Forceps Biopsy Via a Tunnel in Diagnosing Mediastinal Lymphadenopathy: a Multicenter Randomised Controlled Trial.

The goal of this prospective, multi-centre, randomised controlled clinical study is to compare the diagnostic yield and safety of the three biopsy techniques (EBUS-TBNA, EBUS-TBMC via a tunnel, and EBUS-TBFB via a tunnel) in mediastinal/hilar lymph node biopsies.

Participants will divided into EBUS-TBNA group, EBUS-TBMC via a tunnel group, and EBUS-TBFB via a tunnel group at a 1:1:1 ratio by using central, computerized random sequence, and then undertake EBUS-TBNA, EBUS-TBMC via a tunnel, or EBUS-TBFB according to the group.

Researchers will compare the diagnostic yield and incidence of adverse events of the three biopsy techniques.

Being tested
EBUS-TBNA, EBUS-TBMC via a tunnel, EBUS-TBFB via a tunnel

What participants receive

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

  • EBUS-TBNAProcedure or surgery

    Also called Endobronchial ultrasound-guided transbronchial needle aspiration.

    A 22G biopsy needle was insert into the lesion through tracheal-bronchial wall under real-time EBUS guided by bronchoscopist. Needle punctures were performed by using the jabbing method. Once it is confirmed that the puncture needle is within the target lesion, the puncture needle is moved back and forth while suction (An empty 50 ml syringe was connected to the port at the end of the puncture needle and aspirated to 20 ml maintained for 20 seconds.) is applied. Each lymph node was operated 5 times.

  • EBUS-TBMC via a tunnelProcedure or surgery

    Also called endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy via a tunnel.

    First a tunnel between airway wall and mediastinal and/or hilar lesion was made by a puncture dilation catheter (BroncTruTM AK-91-55, Bronchus Inc. Hangzhou, China). The 1.1mm cryoprobe (Erbe 20402-401, ERBE, Tübingen, Germany) entered the target lymph node through the tunnel under direct monitoring of EBUS, and the distance between the tip of the cryoprobe and the border of target lymph node was measured using EBUS. After confirming that the distance was >5 mm, the probe was cooled with liquid carbon dioxide for 5-9 seconds. Then retracted with the bronchoscope and the frozen biopsy tissue. Samples were retrieved by thawing in saline and then fixed in formalin. The same lymph node was operated for 3 times.

  • EBUS-TBFB via a tunnelProcedure or surgery

    Also called endobronchial ultrasound-guided transbronchial forceps biopsy

    Firstly, a tunnel to reach the lymph node is established by making use of a puncture dilation catheter, and a 1.5mm biopsy forceps is pushed into the lymph node through the working channel of the ultrasound bronchoscope. After entering the lymph node, the biopsy forceps were opened proximally to the lymph node, the biopsy forceps were advanced, and then the biopsy forceps were closed distally to the lymph node for each specimen. Each lymph node was operated 5 times.

What is being measured

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

  1. Dignostic yield of EBUS-TBNA, EBUS-TBMC via a tunnel, and EBUS-TBFB

    The proportion of participants in whom the biopsy led to a definitive diagnosis.

    Measured: 7 days after the biopsy

  2. Incidence rate of adverse events

    Symptoms and signs

    Measured: 7 days after the biopsy

  3. the adequacy of sample acquisition

    Samples resulting in a specific diagnosis or samples with the presence of lymphpcytes were considered as adequate.

    Measured: 7 days after the biopsy

Secondary outcomes (1)
  1. the adequacy of sample acquisition

    Samples resulting in a specific diagnosis or samples with the presence of lymphpcytes were considered as adequate.

    Measured: 7 days after the biopsy

Dignostic yield of EBUS-TBNA, EBUS-TBMC via a tunnel, and EBUS-TBFB (time frame: 7 days after the biopsy). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06262620, which also lists 2 linked publications.
