1Clinical implications of neutrophil-to-lymphocyte ratio and MDSC kinetics in gastric cancer patients treated with ramucirumab plus paclitaxel显示文摘Objective: We aimed to investigate the prognostic value of neutrophil-to-lymphocyte ratio(NLR) and myeloidderived suppressor cells(MDSCs) in gastric cancer patients treated with second-line ramucirumab plus paclitaxel.Methods: A total of 116 patients with advanced or metastatic gastric cancer who receive ramucirumab plus paclitaxel were prospectively enrolled. Fresh blood samples were collected before and after treatment, and flow cytometry was performed to assess the proportions of monocytic(m MDSCs) and granulocytic MDSCs(g MDSCs).Results: Median age was 58 years and 71(61.2%) patients were male. A baseline NLR≥2.94 was associated with significantly poorer progression-free survival(PFS) and overall survival(OS) vs. an NLR<2.94(P=0.011 and P=0.002, respectively). In multivariate analysis, an NLR≥2.94 was independently associated with poorer PFS[hazard ratio(HR)=1.58;95% confidence interval(95% CI): 1.01-2.49, P=0.046] and OS(HR=1.77;95% CI:1.04-3.04, P=0.036). While m MDSC counts did not significantly change following two cycles of therapy(P=0.530),g MDSC counts decreased significantly after two treatment cycles(P=0.025) but tended to increase in patients with progressive disease after two treatment cycles(P=0.098). A progressive increase in g MDSC counts(≥44%) was associated with a significantly shorter PFS and OS vs. a g MDSC count increase <44%(P=0.001 and P=0.003,respectively).Conclusions: The baseline NLR may help guide clinical decisions during ramucirumab plus paclitaxel therapy for gastric cancer. Our g MDSC kinetics data warrant further clinical validation and mechanistic investigation.Hyung-Don Kim Min-Hee Ryu Sangsoon Yoon Young-Soon Na Meesun Moon Hyungeun Lee Hyung Geun Song Yoon-Koo Kang 2020Chinese Journal of Cancer Research2020,32,5:4
