OBJECTIVES To understand underlying changes in pretreatment serum inflammatory markers associated with thymic epithelial tumors (TETs) development. METHODS A retrospective analysis of 113 TETs patients who underwent 18-fluorine fluorodeoxyglucose (18F-FDG) positron emission tomography combined computed tomography (PET/CT) one to two weeks before tumor resection or biopsy was performed. Pretreatment serum neutrophil, monocyte, platelet, and lymphocyte counts, and fibrinogen and C-reaction protein (CRP) concentrations were measured one day before surgery or biopsy. Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) were calculated by dividing corresponding cells counts by lymphocyte counts, respectively. The maximum standard uptake value (SUVmax) of 18F-FDG of primary TETs was applied to reflect tumor glycolytic activity. The student's t-test, one-way ANOVA analysis, Chi-square test, receiver operating characteristic curve analysis, and Logistic regression analysis were used for statistical analysis. RESULTS The serum NLR and MLR were significantly higher in TETs patients than in healthy volunteers (P both ≤ 0.001). High serum NLR and MLR were related to the thymic carcinomas (TCs) subtype, elevated Masaoka-Koga (M-K) tumor stage, and metastasis of TETs (P all < 0.005). High serum NLR and MLR were also associated with high SUVmax values of TETs (P all < 0.005), with increasingly differences between groups as the cut-off values defining low-SUVmax and high-SUVmax groups increased. With the medium cutoff of NLR, MLR, and SUVmax of 3.07, 0.25, and 8.00 respectively, the high NLR and MLR levels were significantly associated with high SUVmax level of TETs (P both < 0.005). Moreover, the incidences of co-high SUVmax/NLR and co-high SUVmax/MLR were higher in TETs patients older than 55 years, with TCs, in M-K stage IV, and with metastasis (P all < 0.05). Both the co-high SUVmax/NLR and co-high SUVmax/MLR increased the risk of TETs metastasis (P both < 0.001), while the co-high SUVmax/MLR was also an independent risk factor for TETs metastasis (odds ratio: 3.92, 95% confidence interval: 1.02-15.12, P = 0.047). CONCLUSION Pretreatment serum NLR and MLR of TETs patients are two tumor-progression- and tumor-glycolysis-related inflammatory markers. Enhanced tumor glycolytic activity and associated systemic inflammatory reaction may play a synergistic role in TETs metastasis.

预处理血清中性粒细胞与淋巴细胞和单核细胞与淋巴细胞的比率:胸腺上皮肿瘤患者的两种肿瘤相关全身炎症标志物

目的 了解与胸腺上皮肿瘤 (TET) 发展相关的治疗前血清炎症标志物的潜在变化。方法 对 113 名 TET 患者进行回顾性分析,这些患者在肿瘤切除或活检前一到两周接受了 18-氟氟脱氧葡萄糖 (18F-FDG) 正电子发射断层扫描联合计算机断层扫描 (PET/CT)。在手术或活检前一天测量治疗前血清中性粒细胞、单核细胞、血小板和淋巴细胞计数,以及纤维蛋白原和 C 反应蛋白 (CRP) 浓度。中性粒细胞与淋巴细胞的比率(NLR)、单核细胞与淋巴细胞的比率(MLR)和血小板与淋巴细胞的比率(PLR)分别通过将相应的细胞计数除以淋巴细胞计数来计算。应用初级 TET 的 18F-FDG 的最大标准摄取值 (SUVmax) 来反映肿瘤糖酵解活性。使用学生t检验、单因素方差分析、卡方检验、受试者工作特征曲线分析和Logistic回归分析进行统计分析。结果TETs患者血清NLR和MLR显着高于健康志愿者(P均≤0.001)。高血清 NLR 和 MLR 与胸腺癌 (TC) 亚型、升高的 Masaoka-Koga (MK) 肿瘤分期和 TET 转移有关(P 均 < 0.005)。高血清 NLR 和 MLR 也与 TET 的高 SUVmax 值相关(P 均 < 0.005),随着定义低 SUVmax 和高 SUVmax 组的临界值增加,组间差异越来越大。NLR、MLR 和 SUVmax 的中等截止值为 3.07,0。分别为 25 和 8.00,高 NLR 和 MLR 水平与 TET 的高 SUVmax 水平显着相关(P 均 < 0.005)。此外,55岁以上TETs、TCs、MK IV期和转移患者的SUVmax/NLR和SUVmax/MLR同时升高的发生率更高(P均<0.05)。co-high SUVmax/NLR 和 co-high SUVmax/MLR 都增加了 TETs 转移的风险(P 均 < 0.001),而 co-high SUVmax/MLR 也是 TETs 转移的独立危险因素(优势比:3.92 , 95% 置信区间:1.02-15.12,P = 0.047)。结论 TETs患者治疗前血清NLR和MLR是肿瘤进展和肿瘤糖酵解相关的两种炎症标志物。增强的肿瘤糖酵解活性和相关的全身炎症反应可能在 TETs 转移中发挥协同作用。和 8.00,高 NLR 和 MLR 水平与 TET 的高 SUVmax 水平显着相关(P 均 < 0.005)。此外,55岁以上TETs、TCs、MK IV期和转移患者的SUVmax/NLR和SUVmax/MLR同时升高的发生率更高(P均<0.05)。co-high SUVmax/NLR 和 co-high SUVmax/MLR 都增加了 TETs 转移的风险(P 均 < 0.001),而 co-high SUVmax/MLR 也是 TETs 转移的独立危险因素(优势比:3.92 , 95% 置信区间:1.02-15.12,P = 0.047)。结论 TETs患者治疗前血清NLR和MLR是肿瘤进展和肿瘤糖酵解相关的两种炎症标志物。增强的肿瘤糖酵解活性和相关的全身炎症反应可能在 TETs 转移中发挥协同作用。和 8.00,高 NLR 和 MLR 水平与 TET 的高 SUVmax 水平显着相关(P 均 < 0.005)。此外,55岁以上TETs、TCs、MK IV期和转移患者的SUVmax/NLR和SUVmax/MLR同时升高的发生率更高(P均<0.05)。co-high SUVmax/NLR 和 co-high SUVmax/MLR 都增加了 TETs 转移的风险(P 均 < 0.001),而 co-high SUVmax/MLR 也是 TETs 转移的独立危险因素(优势比:3.92 , 95% 置信区间:1.02-15.12,P = 0.047)。结论 TETs患者治疗前血清NLR和MLR是肿瘤进展和肿瘤糖酵解相关的两种炎症标志物。增强的肿瘤糖酵解活性和相关的全身炎症反应可能在 TETs 转移中发挥协同作用。00 分别表明,高 NLR 和 MLR 水平与 TET 的高 SUVmax 水平显着相关(P 均 < 0.005)。此外,55岁以上TETs、TCs、MK IV期和转移患者的SUVmax/NLR和SUVmax/MLR同时升高的发生率更高(P均<0.05)。co-high SUVmax/NLR 和 co-high SUVmax/MLR 都增加了 TETs 转移的风险(P 均 < 0.001),而 co-high SUVmax/MLR 也是 TETs 转移的独立危险因素(优势比:3.92 , 95% 置信区间:1.02-15.12,P = 0.047)。结论 TETs患者治疗前血清NLR和MLR是肿瘤进展和肿瘤糖酵解相关的两种炎症标志物。增强的肿瘤糖酵解活性和相关的全身炎症反应可能在 TETs 转移中发挥协同作用。00 分别表明,高 NLR 和 MLR 水平与 TET 的高 SUVmax 水平显着相关(P 均 < 0.005)。此外,55岁以上TETs、TCs、MK IV期和转移患者的SUVmax/NLR和SUVmax/MLR同时升高的发生率更高(P均<0.05)。co-high SUVmax/NLR 和 co-high SUVmax/MLR 都增加了 TETs 转移的风险(P 均 < 0.001),而 co-high SUVmax/MLR 也是 TETs 转移的独立危险因素(优势比:3.92 , 95% 置信区间:1.02-15.12,P = 0.047)。结论 TETs患者治疗前血清NLR和MLR是肿瘤进展和肿瘤糖酵解相关的两种炎症标志物。增强的肿瘤糖酵解活性和相关的全身炎症反应可能在 TETs 转移中发挥协同作用。高 NLR 和 MLR 水平与 TET 的高 SUVmax 水平显着相关(P 均 < 0.005)。此外,55岁以上TETs、TCs、MK IV期和转移患者的SUVmax/NLR和SUVmax/MLR同时升高的发生率更高(P均<0.05)。co-high SUVmax/NLR 和 co-high SUVmax/MLR 都增加了 TETs 转移的风险(P 均 < 0.001),而 co-high SUVmax/MLR 也是 TETs 转移的独立危险因素(优势比:3.92 , 95% 置信区间:1.02-15.12,P = 0.047)。结论 TETs患者治疗前血清NLR和MLR是肿瘤进展和肿瘤糖酵解相关的两种炎症标志物。增强的肿瘤糖酵解活性和相关的全身炎症反应可能在 TETs 转移中发挥协同作用。高 NLR 和 MLR 水平与 TET 的高 SUVmax 水平显着相关(P 均 < 0.005)。此外,55岁以上TETs、TCs、MK IV期和转移患者的SUVmax/NLR和SUVmax/MLR同时升高的发生率更高(P均<0.05)。co-high SUVmax/NLR 和 co-high SUVmax/MLR 都增加了 TETs 转移的风险(P 均 < 0.001),而 co-high SUVmax/MLR 也是 TETs 转移的独立危险因素(优势比:3.92 , 95% 置信区间:1.02-15.12,P = 0.047)。结论 TETs患者治疗前血清NLR和MLR是肿瘤进展和肿瘤糖酵解相关的两种炎症标志物。增强的肿瘤糖酵解活性和相关的全身炎症反应可能在 TETs 转移中发挥协同作用。
