目的 探讨维奈克拉(VEN)联合去甲基化药物(HMA)治疗较高危[修订后国际预后评分系统(IPSS-R)评分＞3.5分]的骨髓增生异常综合征(MDS)的疗效及安全性.方法 纳入2021年3月至2022年12月于中国医学科学院血液病医院连续收治的共计45例应用VEN联合HMA方案治疗的较高危MDS患者,回顾性收集并分析临床资料,主要包括性别、年龄、MDS亚型、IPSS-R评分、治疗方案及疗效等,采用Kaplan-Meier法和Cox回归模型进行生存预后的单因素及多因素分析.结果 ①共计45例MDS患者,其中91％患者为IPSS-R评分高危或极高危患者.按照国际工作组(IWG)2023版修订评价标准:总缓解率(ORR)为62.2％(28/45),完全缓解(CR)率为33.3％(15/45).25例初治患者 ORR为 68％(17/25),CR率为 32％(8/25).20例非初治 MDS 患者 ORR为 55％(11/20),CR率为35％(7/20).患者达最佳疗效中位周期数为1(1～4)个.②中位随访时间189d,中位总生存(OS)期为499(95％CI287～711)d,患者死亡多因本病进展.VEN应答者中位OS期明显长于无应答者(499 d对228 d,P＜0.001).③多因素分析显示IPSS-R评分、对治疗反应为影响OS的独立预后因素;存在SETBP 1基因突变可能延长患者住院时间(51.5 d对27d,P=0.017).结论 VEN联合HMA治疗较高危MDS患者存在临床获益,但需警惕治疗过程中发生严重血细胞减低等不良反应.
Objective To investigate the efficacy and safety of combining venetoclax(VEN)with hypomethylated drugs(HMA)in the treatment of higher-risk(IPSS-R score＞3.5)myelodysplastic syndromes(MDS).Methods From March 2021 to December 2022,forty-five MDS patients with intermediate and high risk were treated with VEN in combination with HMAs.Clinical data were collected and analyzed retrospectively,including gender,age,MDS subtype,IPSS-R score,treatment regimen,and efficacy,etc.Kaplan-Meier method and Cox regression model were used to analyze univariate and multivariate of survival prognosis.Results ①Forty-five patients with MDS,including ninety-one percent were classified as high or very high risk.According to the 2023 consensus proposal for revised International Working Group response criteria for higher-risk MDS,the overall response rate(ORR)was 62.2％(28/45),with the complete response rate(CR)was 33.3％(15/45).For twenty-five naive MDS,the ORR was 68％(17/25)and the CR rate was 32％(8/25).In nonfirst-line patients,the ORR and CR were 55％(11/20)and 35％(7/20)respectively.The median cycle to best response was 1(1-4).②With a median followup of 189 days,the median overall survival(OS)time was 499(95％confidence interval,287-711)days,and most patients died from disease progression.Responders had a significantly better median OS time than nonresponders(499 days vs 228 days,P＜0.001).Multifactor analysis revealed that IPSS-R score and response to treatment were independent prognostic factors for OS;the presence of SETBP1 gene mutations was associated with a longer hospital stay(51.5 days vs 27 days,P=0.017).Conclusions There is clinical benefit of venetoclax in combination with hypomethylated agents in patients with higher-risk MDS,but adverse events such as severe hypocytopenia during treatment should be avoided.
