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.
  • Presence of mediastinal lymphadenopathy of unknown etiology.
  • Clinical suspicion of lymphoma, based on any of the following:
  • Previous history of lymphoma (suspected relapse). Presence of lymphoma at another site. Clinical and radiographic findings suggestive of new isolated mediastinal lymphoma (e.g., isolated idiopathic bulky mediastinal adenopathy with or without systemic symptoms), as assessed by the study bronchoscopists.

Who cannot join

  • A more probable alternative cause for lymphadenopathy is identified (e.g., lung cancer or other non-lymphoproliferative malignancies).

About this study

The goal of this clinical trial is to learn which of two minimally invasive procedures is better at safely diagnosing lymphoma in the mediastinum (chest) in adults (aged 18 and older) who are suspected to have either a new or a returning (relapsed) lymphoma. The main questions it aims to answer are:

Which procedure, endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-TBMC) or endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), has a higher success rate in obtaining a definitive diagnosis? Is one procedure safer than the other in terms of complications? Researchers will compare the EBUS-TBMC group to the EBUS-TBNA group to see if the cryobiopsy technique leads to better diagnostic results and has a similar or better safety profile.

Participants will:

Be randomly assigned to undergo one of the two diagnostic procedures (EBUS-TBMC or EBUS-TBNA) during a single bronchoscopy session.

Have their tissue samples analyzed by pathologists. Be followed clinically for at least 6 months to confirm the final diagnosis.

What participants receive

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

  • Endobronchial ultrasound-guided transbronchial needle aspirationProcedure or surgery

    After the target lymph nodes are determined and the safety of needle aspiration is ensured, a 19-G needle will be placed in the working channel of the EBUS scope. The tip of the sheath of the needle will be visible on the endobronchial view, and the needle will then be allowed to pierce the airway wall and enter the lymph node using the jabbing technique under direct ultrasound guidance. A 50-mL syringe will be used to collect 20 mL of aspirates, which will be maintained for 20 s. Each lymph node will be sampled five times to optimize the diagnostic yield. Five passes per node are planned. The samples will not be evaluated on site.

  • Endobronchial ultrasound-guided tranbronchial mediastinal cryobiopsyProcedure or surgery

    After the target lymph node is located (vascular structures will be excluded via the Doppler function), a tunnel will be made between the target lymph node and the airway wall using a 19-G needle. Subsequently, a 1.1-mm cryoprobe (Erbe 20 402-401, ERBE, Tübingen, Germany) will be inserted through the tunnel and positioned within the target lymph node under EBUS monitoring. The distance between the cryoprobe tip and the lymph node edge will be confirmed to be >5 mm in all four directions. Afterward, the probe will be cooled in liquid carbon dioxide for 5-9 s. A total of three passes will be performed.

Questions about this trial

What is this clinical trial studying?

A study testing Endobronchial ultrasound-guided transbronchial needle aspiration and Endobronchial ultrasound-guided tranbronchial mediastinal cryobiopsy in people with Mediastinal and Hilar Lymphadenopathy, run by China-Japan Friendship Hospital.

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 4 inclusion and 1 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: opening soon, as of the sponsor's last update on 20 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

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?

Diagnostic yield (time frame: 7 days after sampling). 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 20 Jan 2026.
