High-quality data from prospective trials are lacking for the elderly sub-population. This systematic review and meta-analysis aims to review the efficacy and safety of immunotherapy in older patients. Methods: A systematic literature search was conducted. Randomized clinical trials providing outcome data on a subgroup of elderly (>65y) were available for meta-analysis. Primary outcomes of interest were OS and PFS for efficacy analysis. Results: Seven studies were included in the systematic review, and four in the efficacy analysis. The pooled analysis of OS and PFS showed a consistent benefit (HR 0.78 and 0.91, respectively). Conclusions: immunotherapy may be an effective and well-tolerated treatment option in the elderly population, but more prospective and randomized data are needed.
