Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Exposure: patients whose mediastinal lymph node sample was taken using Acquire Needle (manufacturer: Boston Scientific).

All patients who are referred to mediastinal/hilar lymph node sampling will be screened. Sampling is done by interventional pulmonologists and there are 2 needs available to taking samples.

We denoted Acquire needle (Boston Scientific) as "interventional" as it is newer but technically we are not intervening but rather comparing 2 methods of obtaining samples. Acquire needles have 3 cut points and pierces lymph nodes easier.

The procedure usually takes 45 min (including anaesthesia, examining bronchi then examining lymph nodes and taking samples). All procedures are done by an interventional pulmonologist or a trainee under direct supervision.

Diagnosis / Prognosis
Comparator / control treatment
Control: patients whose mediastinal lymph node sample was taken using ViziShot Needle (manufacturer: Olympus)

ViziShot needles are similar to conventional needles used for withdrawing bloods. Its tip is different of Acquire and hence it is being compared to see if one needle is superior. We denoted ViziShot as "Control" as it has been used for longer period in interventional pulmonology field. However, it is a comparative study rather than "interventional" where all participants receive the same treatment except for the intervention. In this study, we are only randomising which needle used to take biopsy rather than "intervening" with any process.

All procedures are done by an interventional pulmonologist or a trainee under direct supervision.

Active

Outcomes
Primary outcome [1] 328902 0
Proportion of diagnostic samples per needle of out all needle aspirations. Samples will be transferred to slides that are examined by on site cytologist and will be denoted as "sufficient material" or non-sufficient (ie bloods)
Timepoint [1] 328902 0
Immediately post-aspiration procedure.
Primary outcome [2] 328903 0
Complications related to lymph node aspiration (pneumothorax or haemoptysis or infection or unexpected visit to ED)
Timepoint [2] 328903 0
Participants will be phoned between 7-10 days post-aspiration procedure to check these outcomes.
Primary outcome [3] 328904 0
Proportions of needle failure (ie how often interventional pulmonologist has to change needle used take biopsy). This will be written by the proceduralist on study specific form immediately post procedure.
Timepoint [3] 328904 0
Evaluated immediately during procedure and to be written on study specific form.
Secondary outcome [1] 400832 0
Proportions of participants who needed repeat procedure. This will be collected by checking medical records that participants had or did not have a repeat procedure.
Timepoint [1] 400832 0
Evaluated 6 weeks after aspiration procedure.
Secondary outcome [2] 400833 0
Time taken to perform procedure using each needle determined by digital watch.
Timepoint [2] 400833 0
Immediately post-aspiration procedure.

Eligibility
Key inclusion criteria
All patients referred to Transbronchial Node Aspiration (TBNA) by Endoscopic Ultrasound (EBUS) that meet the following criteria:
- Adults (defined as older than or equal to 18 years of age). There is no upper limit of age provided participants can consent.
- Outpatient/Elective admission to perform the procedure
- Not on anticoagulation (or withheld prior to procedure). Aspirin is ok
- Able to consent
- First TBNA (linear) EBUS (not a redo procedure and no linear EBUS with last 8 weeks).
- Repeat EBUS due to participants intolerance is considered to be failure of bronchoscopy/sedation rather than failure of biopsy needle. The failed procedure results will be not be counted
- At least 1 lymph node size greater or equal to 10 mm
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- Unable to consent, this includes but not limited to participants with dementia, intellectual difficulties, or inability to communicate.
- Contraindication to taking biopsy – ie on anticoagulation or dual antiplatelets therapy within 48 hrs of procedure or INR > 1.5
- Inpatients (due to being sick, likely less time to consider participation and making an informed consent). To clarify, inpatients refer to patients who were admitted via emergency department and does not include elective admission to facilitate a procedure or investigations such as who live far away from Lyell McEwin Hospital.

Study design
Purpose of the study
Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Centralised randomisation via Redcap software (once a patient is enrolled, Redcap randomises this patient to either Acquire needle or ViziShot needle).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomisation table was created using permuted block randomisation. R software is used to generate random sequence. Randomisation is stratified by first targeted biopsy site (hilar versus mediastinal location)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s


Intervention assignment

Type of endpoint/s
Statistical methods / analysis
We anticipate that Acquire needle has 87% successful first pass while ViziShot has 64% successful pass rate. Based on these estimates, a sample size of 108 (54 in each group) provides a power of 80% to detect this difference.

Data analysis will be performed using R statistics. Using mixed logistic model, we aim to calculate the odds of a diagnostic pass after adjusting for location and number of lymph node(s) targeted for sampling.
