Immune checkpoint inhibitors (ICIs) offer a more tolerable alternative to chemotherapy, but their efficacy and safety in elderly non-small cell lung cancer (NSCLC) patients remain underexplored due to limited representation in clinical trials. A narrative literature review was conducted using PubMed, Embase, and the Cochrane Library to evaluate studies on elderly NSCLC patients (≥65 years) treated with ICIs. Key outcomes assessed included overall survival, progression-free survival, response rates, treatment-related adverse events, and the influence of immunosenescence on treatment efficacy. The review highlighted evidence supporting the efficacy and safety of ICIs in elderly NSCLC patients, particularly those with good performance status. Age-related immunosenescence may affect outcomes, emphasizing the need for individualized treatment. Limited data suggest ICIs alone maybe preferable to chemo-immunotherapy for patients over 75 years. However, the exclusion of elderly patients from clinical trials and methodological limitations reduces the generalizability of these findings. ICIs hold promise for advanced NSCLC in older adults, but tailored approaches and greater elderly inclusion in trials are needed to optimize outcomes.  \nKeywords: lung cancer; elderly patients; immune checkpoint inhibitors; non-small cell lung cancer; immunosenescence  \n1. Introduction  \nLung cancer is a significant health concern worldwide. In 2020 alone, nearly 1.8 million deaths were reported out of 2.2 million newly diagnosed cases [1,2] . The agestandardized incidence rate of lung cancer, which measures the number of new cases per 100,000 individuals each year, shows considerable variation across different countries. For instance, Denmark reports a rate of 36.8 per 100,000, while Mexico has a considerably lower rate of 5.9 per 100,000 [3,4] . This disease is a significant concern in developing countries like China, wh","cbCaimeKdM2rpTY2","https://ap.wps.com/l/cbCaimeKdM2rpTY2","pdf",823826,17,"English","# Introduction\n## Epidemiology and burden in older adults\n## Age-related differences in immunotherapy responses\n# Abstract\n# Keywords","[{\"question\":\"Why are elderly patients with advanced NSCLC considered a special population for immunotherapy?\",\"answer\":\"They are more likely to have comorbidities and reduced organ function, which can limit tolerability of chemotherapy and complicate treatment decisions.
