Study design	Observational, prospective, pilot study
Secondary study design
Study type	Participant information sheet
Scientific title	A cohort study to investigate whether radiolabelled lung nodule localisation and excision is a technically successful and reliable method for excision, in patients with small lung nodule: a observational, prospective, pilot study
Study acronym	Radio-labelled excision of lung nodules (RLELN)
Study objectives	Injection of small pulmonary nodules with radiolabelled material will improve accurate localisation, aid early resection of these nodules and will optimize patient management with resultant improved outcome.
Ethics approval(s)	NRES Committee North West - Lancaster, 27/05/2015, ref: 15/NW/0369
Health condition(s) or problem(s) studied	Lung cancer or lung nodules of indeterminate origin
Intervention	Patients with very small nodules not amenable to excision via VATS surgery will be offered the option of radionucleotide injection of their nodules with VATS resection performed on the same day as an alternative to thoracotomy. Patients will be identified from lung cancer multi-disciplinary (MDT) meetings. These MDT meetings are already an integral part of the researchers thoracic surgery services. They meet these patients to discuss their options for the management of these lung nodules and convey them the decision of the MDT. Patient makes a choice and an informed consent is taken. This new treatment option will be discussed as part of their treatment options. The procedure will entail an admission to hospital (as per routine practice for patients who are due to undergo surgery). All patients will sign an informed consent form. They will have an injection of radio labelled substance under local anaesthesia by a consultant radiologist in the CT scan room. This is the same technique which is employed for CT guided lung biopsies which is a well-established procedure and the radiology team are well experienced in its conduct. After this procedure the patient will return to the ward and later that day they will come to theatres, have a general anaesthetic and undergo a minimally invasive excision (key hole surgery) of the nodule in question. The researchers will use the same key hole surgical technique that they routinely employ for larger nodules excision which they are able to see and feel, but the difference will be that they will use intraoperative gamma probe to detect the exact location of the nodule within the lung tissues. The recovery period from this operation will be about 2-4 days.
Intervention type	Procedure/Surgery
Primary outcome measure(s)	Technical success of lung nodule excision., assessed via histological confirmation of complete excision of nodule
