Follow-up after lung cancer resection: is intensified also justified?

In patients who undergo complete resection of a nonsmall cell lung cancer (NSCLC) post-operative followup to detect locoregional and distant recurrences is indicated in order to find potentially treatable lesions at an early stage. There is also an increased risk of developing a second primary lung cancer, unrelated to the previous tumour. Thus, secondary screening may also be worthwhile in this patient population.
