How long persistent and stable ground-glass nodules (GGNs) should be followed is uncertain, although a minimum of 3 years is suggested. Here, we evaluated a group of GGNs that had remained stable for an initial period of 3 years with the aim of determining the proportion of GGNs showing subsequent growth after the initial 3 years and identifying the clinical and radiologic factors associated with subsequent growth. ⋯ For the individuals with GGNs having the aforementioned risk factors, the longer follow-up period is required to confirm subsequent GGN growth.

Crizotinib and ceritinib have been developed to treat advanced or metastatic NSCLC by inhibiting anaplastic lymphoma receptor tyrosine kinase gene (ALK). No randomized trial has compared these treatments head-to-head. We compared efficacy outcomes between patients receiving ceritinib and an external control group receiving crizotinib, both as initial ALK-targeted therapies for previously treated advanced or metastatic ALK-positive NSCLC. ⋯ In an adjusted comparison across separate clinical trials, ceritinib was associated with prolonged OS and PFS compared with crizotinib when used as initial ALK-targeted therapy for previously treated ALK-positive NSCLC.
