Checkpoint inhibitors in NSCLC for the elderly: current challenges and perspectives

Introduction: In the elderly non-small cell lung cancer (NSCLC) is more commonly diagnosed in advanced stages. Conservative therapy including chemotherapy in this age group might be challenging because one of the criteria for its indication is the appropriate functional status, and in the elderly this is more difficult to ascertain. Checkpoint inhibitors are recent therapies found to be effective alone or in combinations in patients with advanced NSCLC, but little is known about their efficacy and their safety in such patients.Areas covered: We review clinical studies of checkpoint inhibitors in patients with advanced NSCLC in an attempt to identify peculiarities related to their use in the elderly. The clinical studies discussed enrolled a significant proportion of elderly patients and for some compounds, post-hoc analysis in the elderly was performed. Efficacy data supports the use of such compounds in the elderly and the safety profile is acceptable for all molecules discussed.Expert opinion: In the elderly with advanced NSCLC, checkpoint inhibitors are efficacious and well tolerated and may be appropriate for use in patients with an increased impaired functional status. Furthermore, in this category of patients this therapy may be used as a neoadjuvant therapy in order to improve the resectability of the tumor.
