Abstract
Background: CHEST guidelines on lung cancer screening during the COVID-19 pandemic1 support delaying interval scans for 3-6 months. There is a concern that progression during this time could result in a higher stage at diagnosis. To determine the safety of this approach, we investigated whether time to interval scan was associated with disease stage at diagnosis.
Method: The SUMMIT Study aims to assess the implementation of low-dose CT for lung cancer screening in a high-risk population and to validate a multi-cancer early detection blood test. Indeterminate nodules are followed up at 3 months.
Participants with interval scans delayed to ≥4 months due to the pandemic and a comparison pre-pandemic group with scans performed at the target timeframe of 3-4 months were identified. Outcomes from cases referred for definitive assessment following interval scan were analysed.
Results:
outlines referrals made and clinical stage of lung cancer diagnoses.
Conclusion: Preliminary data does not suggest a shift to higher stage at diagnosis from delayed interval scans performed at 4-6 months. Whilst this must be validated with additional cases, if confirmed this evidence supports the safety of the CHEST guidelines for lung cancer screening during the COVID pandemic.
