Stenting of central lesion and subsequent standard palliative treatment and dyspnoea symptom control

Standard palliative treatment and standard dyspnoea symptom control.

Patients will undergo arterial blood gas sampling from the radial artery. This will be done by experienced doctors who are highly skilled in this procedure.

Arterial puncture

Blood samples for baseline biochemistry, full blood count, and clotting screen will be taken. In patients additionally providing optional consent blood will be taken for laboratory based basic science research into lung cancer carcinogenesis and pharmacogenetics. Blood will be taken by qualified and experienced nurses, doctors and phlebotomists.

Venepuncture

Patients randomised into the stenting arm will undergo rigid bronchoscopy under general anaesthetic.

General anaesthetic

Patients randomised into the stenting arm will be admitted overnight for the procedure

Inpatient stays

All patients will be asked to complete a 6 minute walking test at baseline and on day 15. Patients randomised into the stent arm (Arm A) will complete a further 6 minute walking test at 24 hours post-stent

Walking test

All patients will undergo spirometry and flow volume loop assessments at baseline and on day 15.

Spirometry & flow volume loop assessment

For patients randomised to stenting and giving additional voluntary consent, 2 pairs of biopsies of tumour tissue, and 1 pair of biopsies of normal airways tissue will be taken for basic scientific research into lung cancer carcinogenesis, and pharmacogenetics.

To investigate whether the use of airways stents (metal tubes to open and keep open narrowed airways) together with the standard treatment increases the proportion of patients who can complete a 6min walking distance (6MWD) test at 2 weeks +/- 2days in patients with breathlessness due to lung cancer, when compared to standard treatment alone.
