Surveillance Imaging Findings of Lung Cancer Recurrence after Definitive Therapy

The authors investigate the role of surveillance imaging, particularly chest CT, in detecting lung cancer recurrence after definitive therapy. They highlight the various patterns of recurrence—local, regional, and distant—and emphasize the importance of understanding tumor histologic features and treatment modalities in predicting recurrence risk. The study aims to improve diagnostic accuracy and patient care by identifying characteristic imaging patterns associated with lung cancer recurrence.
