Summary

This study will compare two clinically accepted protocols for surveillance imaging in individuals who are found to have a small pulmonary nodule on chest computed tomography (CT) scans.

Conditions

  • Solitary Pulmonary Nodule
  • Coin Lesion, Pulmonary
  • Lung Neoplasms
  • Carcinoma, Non-small-cell Lung

Interventions

OTHER

More Frequent Surveillance Strategy

Chest CT scans to be repeated at 3, 6, 12 and/or 24 months, depending on patient risk factors and nodule size and attenuation (density)

OTHER

Less Frequent Surveillance Strategy

Chest CT scans to be repeated at 3, 6, 12 and/or 24 months, depending on patient risk factors and nodule size and attenuation (density). Overall, participants in the less frequent arm are expected to undergo 30% fewer surveillance imaging tests.
