Conditions
Brief summary
This study intends to find out if low dose CT scan may be feasible in Queensland to identify early lung cancers in people at highest risk of lung cancer.
Interventions
Low dose CT with multi-detector CT to detect pulmonary nodules and lung cancer in people at high risk of having lung cancer.
This uses a lower than usual dose of CT scanning than conventional CT chest doses to reduce radiation exposure.
The condition that is being screened for is lung cancer.
There will be one low-dose CT screening scan per year for 3 years, with follow up taking an additional 3 years after the last scan.

Inclusion criteria
- Age 60 -74 years and 364 days. - Current or previous cumulative cigarette smoking history of > 30 pack years (packs per day multiplied by the number of years smoked). Former smokers must have quit smoking within the previous 15 years. - With or without asbestos exposure
Exclusion criteria
Exclusion criteria are intended to eliminate from consideration individuals unable to give informed consent or who, by virtue of medical disability, would unlikely survive to the end of the trial period. Also excluded are individuals unlikely to complete curative lung cancer surgery (e.g., thoracotomy with lobectomy or pneumonectomy – i.e. poor lung function), individuals presenting with symptoms suggestive of lung cancer; individuals who have had recent chest imaging; or those with physical conditions that would preclude high quality screening computerised tomography (CT). Other exclusion criteria are: - Inability to lie on the back with arms raised above the head. Supine positioning, with or without the support of pillows under the head or extremities, with arms briefly resting above the head, is required for purposes of acquiring helical CT scans. - Metallic implants or metallic devices in the chest or back (pacemakers or Harrington fixation rods, etc.) that would cause sufficient beam hardening artefact so as to degrade image quality in the lungs. - Prior history of lung cancer. - Computed Tomography (CT)) of the chest within the past 18 months - Treatment for, or advisement by a physician of evidence of any cancer within the past five years, with the exceptions of non-melanoma skin cancer and most in-situ carcinomas. (Treatment for, or evidence of, melanoma or in-situ bladder/transition cell carcinomas within the preceding five years renders the potential participant ineligible.) - Prior removal of any portion of the lung, excluding percutaneous lung biopsy. - Requirement for home oxygen supplementation for respiratory conditions. - Participation in another cancer screening trial - Participation in a cancer prevention trial other than smoking cessation programs. - Present symptoms suggestive of lung cancer, including unexplained weight loss of over 15 lbs (~6.5 kgs) within the past 12 months, or unexplained haemoptysis. - Any medical condition that poses a significant risk of mortality during the 6-year trial period. - Any medical or psychiatric condition precluding informed medical consent.
