摘要
目的 分析多发性骨髓瘤(MM)早期死亡患者的临床特点,为早期识别高危人群及分层治疗提供帮助.方法 收集2008年7月至2012年7月北京协和医院新诊断MM住院患者,对临床和随访资料完整的177例进行回顾性分析.治疗前观察指标包括ISS分期、乳酸脱氢酶(LDH)、髓外侵犯、淀粉样变、血钙等,细胞遗传学(CG)采用荧光原位杂交(FISH)检测5种染色体异常.其他资料包括治疗方案、疗效判断、死亡原因.结果 24个月内死亡的73例患者定义为高危组,生存超过24个月的104例为对照组.两组年龄和性别分布匹配,治疗方案具有可比性,高危组中位总生存(OS)期仅8个月,对照组中位随访38个月OS仍未达到,两组中位OS差异有统计学意义(P<0.001).主要死亡原因两组均为疾病进展.基线指标比较显示高危组以下指标比例显著高于对照组,包括ISSⅢ期[76.71% (56/73)比50.00% (52/104),P=0.002],肾功能不全[47.95% (35/73)比31.73% (33/104),P=0.029],LDH高于正常[20.55%(15/73)比7.69% (8/104),P=0.015],浆细胞白血病(PCL)[5.48% (4/73)比0(0/104),P=0.016].而髓外浆细胞瘤、淀粉样变性和高钙血症比例在两组差异无统计学意义.疗效判断方面,高危组深度反应率[包括完全缓解(CR)+很好部分缓解(VGPR)]显著低于对照组[12.33% (9/73)比53.85% (56/104),P<0.001],总反应率[ORR,包括CR+ VGPR+部分缓解(PR)]也显著低于对照组[38.36%(28/73)比86.54% (90/104),P<0.001].细胞遗传学异常显示lq21扩增比例在高危组与对照组差异有统计学意义[35.62%(26/73)比25.15% (22/104),P=0.033].多因素回归分析显示ISS分期、LDH升高和初始治疗未达PR为影响MM患者早期死亡的独立因素(P=0.046、0.005、<0.00l).结论 24个月内死亡的MM患者ISSⅢ期、LDH升高、1q21扩增和PCL比例显著升高,诱导治疗疗效差,具有这�
Objective To explore the clinical characteristics of multiple myeloma (MM) patients with overall survival (OS) less than 24 months so as to stratify high-risk population.Methods A total of 177 newly diagnosed MM inpatients were recruited from July 2008 to July 2012.Clinical parameters at diagnosis of international staging system (ISS),lactic dehydrogenase (LDH),serum calcium,extramedullary involvement and amyloidosis were collected and cytogenetic abnormalities were detected by fluorescence in situ hybridization (FISH).Response and death were recorded as endpoints.Otherwise the follow-up period was over 24 months.Results And 73 patients dying within 24 months were classified into high-risk group while another 104 survivors for over 24 months into control group.Age and gender at baseline were comparable.However,OS of high-risk group was only 8 months while it was not attained during a median follow up of 38 months in control group (P < 0.001).The most common cause of death was progressive disease in both groups.The pre-treatment percentages of the following parameters were significantly higher in high-risk group,including ISS stage Ⅲ (76.71% (56/73) vs 50.00% (52/104),P =0.002),renal dysfunction (47.95 % (35/73) vs 31.73% (33/104),P =0.029),elevated LDH (20.55% (15/73) vs 7.69% (8/104),P =0.015) and plasma cell leukemia (PCL,5.48% (4/73) vs 0 (0/104),P =0.016).Conversely,extramedullary involvement,plasmacytoma,amyloidosis and hypercalcemia were similar.Despite comparable chemotherapeutic regimens,the rate of deep response,including complete response (CR) and very good partial response (VGPR),was significant lower in highrisk group than that in control group (12.33% (9/73) vs 53.85% (56/104),P < 0.001).Overall response rates (ORR,i.e.CR + VGPR + partial response (PR)) were markedly different (38.36% (28/ 73)vs 86.54% (90/104),P <0.001).Univariate analysis of cytogenetic a
