Is there really a role for the comprehensive geriatric assessment in metastatic non-small cell lung cancer?

Lung cancer is the most common cancer worldwide and the leading cause of cancer-related deaths (1,2). About 50% of patients with non-small cell lung cancer (NSCLC) are older than 65 year-old, and median ages at diagnosis are currently 63–70 in Western countries (3). Due to demographic trends and CT-based screening, incidence of NSCLC in elderly is expected to increase. Therefore, the management of these patients is a challenge for the medical community.
