TY - JOUR AU - Detterbeck, Frank C. PY - 2019 TI - Surveillance of ground glass nodules—when is enough, enough? JF - Translational Lung Cancer Research; Vol 8, Supplement 4 (December 31, 2019): Translational Lung Cancer Research Y2 - 2019 KW - N2 - Lee et al . provide important information about the long-term behavior of ground glass nodules (GGNs) (1). They carried out a retrospective review of 208 GGNs, detected during routine health check-up CT scans (1–3 mm slice thickness), that were stable for 5 years (78% pure GGNs) (1). Growth was defined as an increase in the largest total dimension of ≥2 mm (others have shown high inter- and intra-observer variability for changes of <2 mm) or the development of a new solid component (presumably visible on mediastinal windows although not explicitly stated).
