Many patients with oncogene-driven non-small-cell lung cancer (NSCLC) treated with tyrosine kinase inhibitors experience limited sites of disease progression. This study investigated retrospectively the benefits of local ablative therapy (LAT) to central nervous system (CNS) and/or limited systemic disease progression and continuation of crizotinib or erlotinib in patients with metastatic ALK gene rearrangement (ALK+) or EGFR-mutant (EGFR-MT) NSCLC, respectively. ⋯ Oncogene-addicted NSCLC with CNS and/or limited systemic disease progression (oligoprogressive disease) on relevant targeted therapies is often suitable for LAT and continuation of the targeted agent, and is associated with more than 6 months of additional disease control.

Randomized Controlled Trial
Bevacizumab maintenance in patients with advanced non-small-cell lung cancer, clinical patterns, and outcomes in the Eastern Cooperative Oncology Group 4599 Study: results of an exploratory analysis.
The Eastern Cooperative Oncology Group (ECOG) 4599 study showed a significant survival benefit with the use of bevacizumab (BV) in combination with carboplatin and paclitaxel (CP) in comparison with CP chemotherapy alone in patients with previously untreated advanced, metastatic or recurrent non-small-cell lung cancer (NSCLC). Such results were achieved using BV as maintenance therapy until progressive disease. Because current data on single-agent BV maintenance in non-small-cell lung cancer are limited, we present a retrospective analysis of safety and efficacy outcomes for patients who received maintenance BV after induction treatment and the maintenance-eligible population of the control arm in ECOG 4599. ⋯ In this retrospective analysis of patients in the ECOG 4599 study, who were alive, progression free, and on-study 21 days after six cycles of induction therapy, significant reductions in HRs for progression (0.64, p < 0.001) and survival (0.75, p = 0.03) were associated with BV treatment during induction and maintenance compared with CP induction therapy alone and suggestive of possible benefit because of bevacizumab maintenance.
