Therefore, this study was designed to assess the prognostic significance of the ratio between absolute lymphocyte and monocyte counts (LMR) in the peripheral blood to verify relapse in diffuse large B cell lymphoma. Patients and methods: A total of 139 patients with newly diagnosed diffuse large B cell lymphoma (DLBCL) were evaluated and treated with CHOP or R-CHOP between the years 2009 and 2016. Three months following completion of first line therapy, Lymphocyte/monocyte ratio (LMR) was calculated from the routine automated complete blood cell count (CBC) attained a plateau after the bone marrow recovery after first line chemotherapy. The absolute lymphocyte count/absolute monocyte count ratio (LMR) was calculated by dividing the ALC by the AMC. Results: ROC curve analysis of 139 patients established 2.8 as cutoff point of LMR for relapse with AUC of 0.97 (95% CI 0.93 - 0.99, P ≤ 0.001). Cox regression analysis was performed to identify factors predicting relapse. In univariate regression analysis, ALC (95% CI 0.003 - 0.03, p ≤ 0.001), AMC (95% CI 15.4 - 128.8, p ≤ 0.001), LMR (95% CI 0.001 - 0.01, p ≤ 0.001), and LDH (95% CI 0.1 - 0.5, p ≤ 0.001) following completion of therapy are significant factors for relapse. Other significant factors for relapse are Ann Arbor stage (95% CI 1.1 - 6.9, P = 0.03), extranodal sites (95% CI 1.2 - 6.1, P = 0.01), age (95% CI 1.3 - 6.5, P = 0.01) and treatment of CHOP protocol (95% CI 0.05 - 0.6, P = 0.007). In a multivariate analysis LMR following completion of therapy was predictive for relapse (95% CI 0.001 - 0.2, P = 0.005). ALC was also significant in multivariate analysis (95% CI 0.01 - 0.8, P = 0.03). LDH following completion of therapy (95% CI 0.2 - 14.9, P = 0.5), AMC following completion of therapy (95% CI 0.3 - 43.1, P = 0.3), age (95% CI 0.9 - 205.4, P = 0.06), extra-nodal sites (95% 展开更多

文摘目的通过分析慢性淋巴细胞白血病(chronic lymphocytic leukemia,CLL)患者的临床、实验室及随访资料探讨外周血单核细胞绝对计数(absolute monocyte count,AMC)对CLL的预后价值。方法对2002年1月至2017年12月收住山西医科大学第二医院的54例慢性淋巴细胞白血病患者的临床特点、实验室检查、治疗效果、预后进行分析,探讨影响CLL的预后因素。结果 54例患者中,男女比例为2∶1,中位年龄为64岁;其中Binet A期8例,B期25例,C期21例;以疾病进展作为终点得到外周血AMC的受试者工作特征(receiver operating characteristics,ROC)曲线,AMC的截点值为0.67×109/L,曲线的最佳灵敏度为0.710,特异度为0.783,曲线下面积(area under the curve,AUC)为0.771(95%CI:0.644~0.899)。以0.67×109/L为界限,分为高AMC组和低AMC组,低AMC组的患者无进展生存期优于高AMC组(P<0.05),但高AMC组与低AMC组之间总生存期差异无统计学意义(P=0.170)。Cox回归结果表明疾病分期为C期(P=0.038)是总生存期的独立影响因素,AMC>0.67×109/L(P=0.004)及疾病分期为C期(P=0.049)是无进展生存期的独立影响因素。结论初诊时较高的AMC与CLL较快的疾病进展有关,可能为CLL的预后判断提供新依据。
