A total of 20 patients were enrolled. The number of patients administrated pembrolizumab, nivolumab, and atezolizumab was 12, 7 and 1, respectively. Twelve patients were diagnosed as progressive disease (PD), and 8 were non-PD. All 6 female patients were diagnosed as PD. In the blood sample obtained within 3 weeks from the immune therapy, significantly high CD28 positive CD8+ T lymphocyte counts and low neutrophil counts were observed in the non-PD patients compared with the PD patients. Meanwhile, the distribution of tumor PD-L1 levels, clinical stage of NSCLC, and other immune markers investigated in the non-PD patients were comparable with the PD patients. CD28 positive CD8+ T lymphocyte and neutrophil counts were considered to be possible biomarkers related to the efficacy of PD-1/PD-L1 therapy., 2016年度~2018年度科学研究費補助金(基盤研究(C))研究成果報告書, 16K08369}, title = {免疫チェックポイント阻害薬のPK/PD評価系構築と個別化治療への応用}, year = {2019}, yomi = {イワモト, タクヤ and オクダ, マサヒロ} }
