Tumor-induced peripheral immunosuppression promotes brain metastasis in patients with non-small cell lung cancer

ConclusionsThe frequency of PD-L1+ myeloid cells correlated with the presence of brain metastases.  Tumor-derived IL-6 was capable of inducing PD-L1+ myeloid cells  in vitro, suggesting that monitoring of immunosuppressive factors in peripheral blood may identify new targets for therapeutic intervention in selected patients.
