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

Description of intervention(s) / exposure
Bronchoalveolar lavage (BAL) of lung of patients undergoing bronchoscopy for suspected lung cancer / Lung resected for management of known lung cancer. BAL involves installation of a small amount of saline into the lung, via the bronchoscope, then removing the fluid via suctino to allow diagnosis of cells retrieved within the fluid. This is a standard diagnostic procedure in bronchoscopy.
Analysis of the behaviour of inflammatory cells in lung cancer, specifically, the role tumour-associated lung cancer play in the progression of lung cancer.
We hope to determine the diagnostic and prognostic value of such information

Comparator / control treatment
Bronchoalveolar lavage (BAL) or wedge resection of adjacent lobe (for BAL) or non-tumour-bearing lung (for post-surgical specimens) to attain a "control" specimen

Active

Outcomes
Primary outcome [1] 3959 0
Sensitivity and specificity will be determined following analysis of both cell surface markers of alveolar macrophages, as well as characteristics (eg. phagocytic ability, inducible proteins). The ability of these to determine the diagnosis of cancer will be compared to the gold standard of histologic analysis of surgically resected specimen. Sensitivity (ability to detect a condition if it is present)/Specificity (how specific a positive result is for the particular condition being studied) of analysis of BAL inflammatory cells in determining the diagnosis of peripheral lung lesions.
Timepoint [1] 3959 0
36 months
Secondary outcome [1] 6659 0
Prognositc value of the presence/density/behaviour characteristics of inflammatory - ie. can information obtained from analysis predict whether patients will experience higher or lower rates of disease recurrence after surgery, or longer or shorter survival times following their diagnosis of lung cancer.
