Immunosenescence (iSenescence) correlates with disease progression in advanced non-small cell lung cancer (aNSCLC) patients treated with PD-(L)1 inhibitors (IO)
BACKGROUND: iSenescence is a progressive remodeling of immune functions with a multifactorial etiology (i.e. aging, chronic inflammation, cancer). Although the absence of CD28 and the expression of CD57 and Killer-cell lectin-like receptor G1 (KLRG1) on peripheral T-lymphocytes are potential hallmarks of iSenescence, the characterization of such phenotype in IO-treated aNSCLC patients and the correlation with clinical characteristics and benefit from immunotherapy are currently unknown.
