Abstract
目的探讨弥漫大B细胞淋巴瘤(DLBCL)患者的临床特征和预后因素,评估合并糖尿病(DM)及治疗过程中发生血糖升高对DLBCL预后的影响。方法回顾性收集2009年1月1日至2019年12月31日天津医科大学肿瘤医院及中山大学肿瘤防治中心收治的481例初诊DLBCL患者的临床资料,重点关注其治疗前及治疗中的血糖水平,采用Cox回归风险模型进行单因素分析评估预后影响因素,采用Kaplan-Meier法绘制生存曲线分析血糖异常对DLBCL患者总生存(OS)、无进展生存(PFS)的影响。结果82例(17.0%)患者在诊断DLBCL前患DM,88例(18.3%)患者在DLBCL治疗过程中至少发生一次血糖升高。单因素分析显示,年龄、Ann-Arbor分期、IPI评分、是否合并DM与OS、PFS相关(P值均<0.05)。组间比较显示,合并DM组与治疗过程中血糖升高组的OS和PFS均较无血糖异常组差(OS:P值分别为0.001、0.003,PFS:P值均<0.001),合并DM组与治疗过程中血糖升高组相比OS和PFS的差异均无统计学意义(P值分别为0.557、0.463)。化疗期间血糖控制良好组的OS和PFS优于血糖控制差组(OS:P=0.037,PFS:P=0.007)。结论合并DM是影响DLBCL患者预后的重要因素,治疗过程中血糖升高与DLBCL患者的不良预后相关。
