Detailed Description

The role of ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for the diagnosis of hilar/mediastinal adenopathy is well established. However, different aspiration techniques are available and it's not clear if there's a significant difference between suction vs no suction aspiration. Of great interest is the role of different aspiration techniques in EBUS-TBNA in determining the diagnostic yield for histopathological evaluation, including molecular biology and PD-L1 amplification assessment in lung cancer diagnosis.

In this context, no comparative studies between suction and no suction aspiration have been performed; moreover, considering only suction techniques, no studies evaluated if there's a difference between aspiration with EBUS dedicated syringe and manual aspiration through Cameco syringe. It is very important for clinical practice to definitively assess the non inferiority of no suction techniques in EBUS-TBNA in terms of diagnostic yield, and to provide information regarding the quality of histologic sample to define the best diagnostic strategy.

The study is focused on a minimum of 306 patients who have at least one hilar/mediastinal lymph node > 1 cm on CT scan or hypermetabolic on FDG-PET in at least one approachable lymph nodal station for which a diagnostic cyto-histological assessment is required for clinical purpose. Patients will be randomized 1:1:1 (no suction : passive suction with EBUS dedicated syringe : manual suction with Cameco syringe) by a computer-generated random-allocation system to undergo EBUS-TBNA with one of the three different aspiration techniques. The pathologist provides a final diagnosis and, as secondary endpoint, a qualitative assessment of the sample quality using both a binary and a semi-quantitative score.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Intervention / Treatment

ACTIVE_COMPARATOR: No suction EBUS-TBNA
In this technique the stylet is slowly removed without any kind of device in order to avoid active suction.
Procedure: No suction EBUS-TBNA

The needle is moved from a side to side of the lymphnode for 15 times. Each lymphnode is sampled three times.

The samples obtained will be examined on-site by experienced blinded cytopathologist.All specimens obtained will be send to definitive cytological and histological evaluation and the final diagnosis will be collected and reported on CRFs.
ACTIVE_COMPARATOR: Passive suction through dedicated EBUS-TBNA syringe
After rapid stylet removal, suction is applied through a vacuteiner syringe, without active aspiration.
Procedure: Passive suction through dedicated EBUS-TBNA syringe

The needle is moved from a side to side of the lymphnode for 15 times. Each lymphnode is sampled three times.

The samples obtained will be examined on-site by experienced blinded cytopathologist.All specimens obtained will be send to definitive cytological and histological evaluation and the final diagnosis will be collected and reported on CRFs.
ACTIVE_COMPARATOR: Manual applied suction EBUS-TBNA through a pistol-grip syringe holder
After rapid stylet removal, suction is applied through Cameco syringe pistol, that can apply active suction manually.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
To compare the diagnostic yield of active suction vs passive suction vs no suction EBUS-TBNA in the diagnosis of hilar/mediastinal adenopathies
Time Frame: 36 months
The diagnostic yield is defined as the rate of diagnoses/total of cases. Assuming that the best technique provides a diagnostic yield of 94%, the non inferiority is defined if the difference between the best and the worst method is less than 3% with a non-inferiority limit of 10%.
36 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Adeguacy for molecular assessment in lung cancer
Time Frame: 36 months
Considering only the lung cancer diagnoses, the sample is considered adeguated is if provides all the available molecular evaluations included PD-L1 iperexpression
36 months
Qualitative evaluation of the sample by the pathologist
Time Frame: 36 months
The sample is evaluated by a pathologist that provides a semi-quantitative assessment of the sample, through a cell count: the sample is adeguate only if it contains more than diagnostic 100 cells.
36 months
