Gefitinib, erlotinib, and afatinib are tyrosine kinase inhibitors (TKIs) used for treatment of advanced EGFR-mutated NSCLC. Estimating differences in toxicity between these EGFR TKIs is important for personalizing treatment. ⋯ EGFR TKIs are well tolerated, with less than 10% of patients discontinuing treatment because of AEs. The profile of and risk for toxicities vary between EGFR TKIs and can be used to inform the selection of treatment.

This study examined the association of extent of lung resection, pathologic nodal evaluation, and survival for patients with clinical stage I (cT1-2N0M0) adenocarcinoma with lepidic histologic features in the National Cancer Data Base. ⋯ Surgeons treating patients with stage I lung adenocarcinoma with lepidic features should cautiously utilize sublobar resection rather than lobectomy, and they must always perform adequate pathologic lymph node evaluation.

NSCLC with de novo anaplastic lymphoma receptor tyrosine kinase gene (ALK) rearrangements and EGFR or KRAS mutations co-occur very rarely. Outcomes with tyrosine kinase inhibitors (TKIs) in these patients are poorly understood. ⋯ De novo concurrent ALK/KRAS co-alterations were associated with resistance to ALK TKI treatment in seven out of eight patients. In patients with ALK/EGFR co-alterations, outcomes with ALK and EGFR TKIs seem inferior to what would be expected in patients with either alteration alone, but further studies are needed to clarify which patients with ALK/EGFR co-alterations may still benefit from the respective TKI.

The optimal role for postoperative radiotherapy (PORT) for thymoma and thymic carcinoma remains controversial. We used the National Cancer Data Base to investigate the impact of PORT on overall survival (OS). ⋯ In this large database analysis of PORT for thymic tumors, PORT was associated with longer OS, with the greatest relative benefits observed for stage IIB to III disease and positive margins. In the absence of randomized studies assessing the value of PORT, these data may inform clinical practice.
