Treatment with an ICI and cranial RT was not associated with a significant increase in RT-related AEs, suggesting that use of programmed cell death 1/programmed death ligand 1 inhibitors in patients receiving cranial RT may have an acceptable safety profile. Nonetheless, additional studies are needed to validate this approach.

Introduction: Immunotherapy has revolutionized the treatment of NSCLC, but little is known about the activity of programmed cell death 1 and programmed death ligand 1 blockade across age groups. Methods: We retrospectively evaluated patients with NSCLC who initiated programmed cell death 1 and programmed death ligand 1 inhibitors from January 2013 through July 2017. Medical records and radiographic imaging were reviewed to determine progression-free survival (PFS) and overall survival (OS). We also compared immunotherapy-related toxicities, steroid use, and hospitalizations by age. Results: Of the 245 patients, 26.1% were younger than 60 years, 31.4% were age 60 to 69 years, 31.0% were age 70 to 79 years, and 11.4% were age 80 years or older. The median PFS times by age group were as follows: younger than 60 years, 1.81 months; age 60 to 69 years, 2.53 months; age 70 to 79 years, 3.75 months; and age 80 years or older, 1.64 months (log-rank p value ¼ 0.055). The median OS times by age group were as follows: younger than 60 years, 13.01 months; age 60 to 69 years, 14.56 months; age 70 to 79 years, 12.92 months; and age 80 years or older, 3.62 months (log-rank p value ¼ 0.011). Rates of immunotherapy-related toxicities, steroid use, and hospitalizations did not differ by age. Conclusions: Although the OS and PFS benefits of immunotherapy differ by age, the rates of toxicity are similar regardless of age.

Alectinib demonstrated preliminary antitumor activity in patients with advanced RET-rearranged NSCLC, most of whom had received prior RET inhibitors. Larger prospective studies with longer follow-up are needed to assess the efficacy of alectinib in RET-rearranged NSCLC and other RET-driven malignancies. In parallel, development of more selective, potent RET TKIs is warranted.

Introduction: Capmatinib is approved for MET exon 14altered NSCLC on the basis of activity in targeted therapynaive patients. We conducted a phase 2 study to assess the efficacy of capmatinib in patients previously treated with a MET inhibitor.Methods: Patients with advanced NSCLC harboring MET amplification or MET exon 14 skipping alterations received
