Abstract
Aim: This study aimed to investigate the prognostic value of peripheral naïve and memory CD8+ and CD4+ T cells and other immune cells in patients with oligometastatic non-small cell lung cancer (NSCLC) undergoing radiotherapy (RT).
Methods: A total of 142 patients with oligometastatic NSCLC treated with RT were enrolled, and their blood samples were collected within 3 days before RT. Immune cells were identified by flow cytometry.
Results: Patients with high levels of naïve CD8+ T cells had longer overall survival (OS; p = 0.004) and progression-free survival (PFS; p = 0.001) than those with low levels of naïve CD8+ T cells. Multivariate analyses revealed that naïve CD8+ T cells were independently correlated with OS (p = 0.019) and PFS (p = 0.024).
Conclusions: The results suggest that peripheral naïve CD8+ T cells may be an independent prognostic indicator for patients with oligometastatic NSCLC undergoing RT.
