About this study

Official title: Wet-suction Versus Slow-pull Technique for Endoscopic Ultrasound-guided Fine-needle Biopsy of Solid Lesions: a Multicentric Randomized Controlled Trial

A randomized cross-over study investigating the impact of two different suction techniques on histological yield and sample quality of specimens collected by endoscopic ultrasound biopsy from solid lesions using histology needles.

Being tested
Endoscopic ultrasound-guided fine-needle biopsy

What participants receive

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

  • Endoscopic ultrasound-guided fine-needle biopsyProcedure or surgery

    Solid lesions will be sampled under endoscopic ultrasound guidance using the two techniques (wet-suction and slow-pull)

Study groups in NCT04834193
Study groupRoleWhat they receive
WET-SUCTIONExperimentalThe stylet will be removed and the needle will be pre-flushed with 1-2mL of saline. The lesion will then be punctured, and suction will be applied using a 10-mL pre-vacuum syringe. The sample collected will be pushed into a formalin vial with saline.
Receives: Procedure: Endoscopic ultrasound-guided fine-needle biopsy
SLOW-PULLActive comparatorAfter puncturing the lesion, the stylet will be slowly and gradually withdrawn for at least 40cm. The sample will be pushed into formalin using the stylet.
Receives: Procedure: Endoscopic ultrasound-guided fine-needle biopsy

What is being measured

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

  1. Histologic yield

    The rate of samples containing a tissue "core" (yes/no) for histological evaluation, defined as an intact piece of tissue of at least 550 μ

    Measured: 6 months

Secondary outcomes (4)
  1. Tissue integrity

    Tissue integrity will be evaluated by attributing a score from zero to 3 (3 represents the better outcome), according to the following score system:

    0: No cells/tissue

    1. Cytological specimen (disaggregated cells representative of the target lesion not allowing for tissue architectural assessment)
    2. Histologic microfragments (sample adequate for histological evaluation, namely an architecturally intact piece of tissue but without a "core")
    3. Histologic "core" (defined as an architecturally intact piece of tissue measuring at least 550 μ)

    Measured: 6 months

  2. Blood contamination

    Blood contamination will be evaluated by attributing a score from zero to 3 (3 represents the better outcome), according to the following score system:

    0: Only blood

    1. High blood contamination (>50% of the surface)
    2. Moderate blood contamination (25-50% of the surface)
    3. Low blood contamination (<25% of the surface)

    Measured: 6 months

  3. Tumor fraction

    The rate of samples containing an adequate tumor fraction ≥20 percent (i.e., ≥ 20 percent tumor cells in a background of benign nucleated cells).

    Measured: 6 months

  4. Diagnostic accuracy

    Diagnostic accuracy (defined as the ratio between the sum of true positive and true negative values divided by the number of lesions) will be calculated for each study arm

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Endoscopic ultrasound-guided fine-needle biopsy in people with Endoscopic Ultrasound and Fine-needle Aspiration, run by Azienda Ospedaliera Universitaria Integrata Verona at 1 site in Italy.

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 5 inclusion and 7 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 2 Feb 2023. 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 Italy. 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?

Histologic yield (time frame: 6 months). 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 NCT04834193, which also lists 1 linked publication.

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 2 Feb 2023.
