Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Use of the novel GEN cut biopsy tool in addition to usual conventional radial EBUS biopsy tools . GEN cut tool is a blunt ended thin probe of 1.9mm diameter. This has two inwardly placed very small sharp edges that can shear thin slices of tissue with rotation.
This tool will be introduced through a guide sheath hence improving the safety of the procedure.
The procedure will be performed by a trained bronchoscopist . A bronchoscope is a small flexible tube with a camera at the end of the tube to visualise the windpipes. The tools are introduced through the working channel of this bronchoscope. The procedure will be performed under sedation
Intervention code [1] 299472 0
Diagnosis / Prognosis
Comparator / control treatment
Comparison will be made between the GEN cut biopsy samples and conventional Radial EBUS samples of cytology brush, forceps biopsy and needle aspiration biopsy.
In the conventional sampling method the instruments are introduced through the working channel of the bronchoscope as mentioned previously and biopsies or brushings performed.
Control group
Active

Outcomes
Primary outcome [1] 303770 0
1. Ability to obtain a core biopsy sample that would be suitable for PDL-1 testing. This will be assessed by the study pathologist as to the ability to form a core biopsy from the tissue sample obtained via Gen cut tool and the ability to stain for PDL-1 stain.
Timepoint [1] 303770 0
Each biopsy will be assessed at the end of each procedure for the suitability of PDL-1 testing
It is anticipated that 6 months will be required to complete recruitment of 20 patients
Primary outcome [2] 303771 0
Safety: Composite outcome
1. Pneumothorax: This will be assessed by performing a USS using the M band and sliding sign at the bedside soon after biopsy to check for pneumothorax. If any doubt exist the patient will be sent urgently for a conventional CXR.
2. Bleeding: Following each biopsy the amount of bleeding will be assessed. This is anticipated to be no more than conventional Radial EBUS biopsy bleeding which is negligible and requires only suction.
Timepoint [2] 303771 0

Summary
Brief summary
The aim of this study is to assess the diagnostic ability and safety in obtaining a core biopsy from peripheral lung lesions (PPL) using the novel Gen Cut tool with Radial EBUS.

Who is it for?
You may be eligible to join this study if you are aged 18 years or over and a have a peripheral lung lesions noted on CT chest/Chest X ray that require a biopsy.

Study details

Procedure: Informed consent will be taken for the procedure from the patient. Procedure will be performed under conscious sedation or general anaesthesia according to the institution.
Once the patient is sedated, the bronchoscope "camera" is introduced via the mouth/nose to the required location. Then a thin USS wire called "Radial EBUS" will be introduced to locate the lesion.
Following this the Gen cut biopsy tools will be introduced as the first mode of biopsy.


How this study may be beneficial for research/treatment:
ThIs study is exploring the new biopsy method (Gen cut) that is safer and can benefit many patients from this safer procedure at their hospital without requiring to transfer to a very specialised centre.
