Abstract IA09: Inflammation and immunity in pulmonary premalignancy

Abstract

Abstract Unleashing the immune response against pulmonary premalignancy could transform therapy and outcomes. We are evaluating the mutational landscape of pulmonary premalignancy and the associated premalignant microenvironment by whole-exome DNA sequencing and immunohistochemistry. Remarkably, we find putative neoepitopes and frequent immune-effector cell infiltration as well as evidence of immune suppression in pulmonary premalignancy. These findings suggest that premalignant-associated antigens are recognized and elicit immune responses at the earliest points of lung adenocarcinoma development. Identification of neoepitopes that can be targeted before the development of invasive lung cancer could eventually shift the approach to disease interception through immunoprevention and treatment of the very earliest phase of the disease.
