“…28 General immuno-stimulatory agents, such as interleukin 2 (which stimulates CTL proliferation), and early vaccines have failed to demonstrate activity in lung cancer, achieving a durable benefit in only a limited subset of patients, delivering a modest survival benefit, and being associated with a considerable toxicity burden. [29][30][31] This led to the belief that lung cancer is a poorly immunogenic disease. However, novel and improved immunotherapeutic agents, including a range of vaccines and immuno-oncology agents, are currently in development, and although results are not yet available from Phase 3 clinical trial programs, data from early studies suggest that improved efficacy might be possible.…”
