P66.04 Real World Data: Immunotherapy in Lung Cancer Patients over 65 Years Old in Spain

In the last decade, immunotherapy (IT) has become a key therapeutic tool in lung cancer treatment. The number of elderly patients with this pathology in Spain has been progressively increased in recent years, becoming a representative subgroup nowadays. Studies carried out with IT in these patients are a minority and controversial, generating a need in clinical practice. The aim of the study is to establish clinical and toxicity differences between patients older and younger than 65 years, treated with IT.
