The aim of this study was to investigate the expression of the coinhibitory molecule PD-L1/CD274 in monocytes and dendritic cells (DC) in the blood of lung cancer patients undergoing PD1 inhibitor therapy and to correlate data with patient’s outcome. PD-L1/CD274 expression of monocytes, CD1c+ myeloid DC (mDC) and CD303+ plasmacytoid DC (pDC) was determined by flow cytometry in peripheral blood at immunotherapy onset. The predictive value of the PD-L1/CD274-expression data was determined by patients’ survival analysis. Patients with a high PD-L1/CD274 expression of monocytes and blood DC subpopulations rarely responded to PD1 inhibitor therapy. Low PD-L1/CD274 expression of monocytes and DC correlated with prolonged progression-free survival (PFS) as well as overall survival (OS). The highest PD-L1/CD274 expression was found in CD14+HLA-DR++CD16+ intermediate monocytes. Whereas the PD-L1/CD274 expression of monocytes and DC showed a strong positive correlation, only the PD-L1/CD274 expression of DC inversely correlated with DC amounts and lymphocyte counts in peripheral blood. Our results implicate that a high PD-L1/CD274 expression of blood monocytes and DC subtypes is a risk factor for therapy response and for the survival of lung cancer patients undergoing PD1 inhibitor therapy.

The effects of cytokines (interleukin-2, tumor necrosis factor-alpha and interferon-gamma) on the ability of peripheral blood monocytes and alveolar macrophages to produce oxygen radicals were examined by the chemiluminescence assay in patients with lung cancer. Oxygen radical production by peripheral blood monocytes before stimulation with cytokines was lower in the lung cancer group than in healthy controls, suggesting reduced immune function in lung cancer patients. However, the activity in the lung cancer group was elevated to the control level when the monocytes were stimulated by any of the three aforementioned cytokines. Oxygen radical production by alveolar macrophages did not differ significantly between nonstimulated monocytes from lung cancer patients and those from healthy controls. In the lung cancer group, stimulation of the macrophages with any of the three cytokines elevated their ability to produce oxygen radicals to the same extent as in the control group. The results suggest that stimulation of macrophages by interleukin-2, tumor necrosis factor-alpha or interferon-gamma can exert an antitumor action in patients with lung cancer.
