Chronic myelomonocytic leukemia (CMML) is a rare hematologic malignancy with overlapping features of myelodysplastic neoplasm (MDS) and myeloproliferative neoplasms characterized by peripheral blood monocytosis [1]. There is a predisposition for transformation to acute myeloid leukemia (AML), termed CMML with blast transformation (CMML-BT) [2, 3]. Hypomethylating agents (HMAs) are the sole FDA approved therapy for CMML albeit without established efficacy in terms of prolonging overall survival (OS) and halting disease evolution [4,5,6]. In order to improve response rates, venetoclax (VEN) has been combined with HMAs extrapolating data from AML and MDS [7, 8]. Single centers have offered varied results on the added benefit of VEN to HMA therapy in CMML and CMML-BT [9,10,11], but these studies lack control cohorts and are limited by small sample sizes of patients evaluated in each treatment setting and disease category.

To clarify the role of upfront HMA + VEN in patients with CMML and CMML-BT, we performed a multicenter retrospective cohort study utilizing a propensity score matched (PSM) cohort of patients treated with HMA alone.

维奈托克联合低甲基化药物治疗慢性粒单核细胞白血病:倾向评分匹配的多中心队列研究



慢性粒单核细胞白血病(chronic myelomonocytic leukemia, CMML)是一种罕见的血液系统恶性肿瘤,具有骨髓增生异常肿瘤(myelodysgenerative neoplasm, MDS)和以外周血单核细胞增多症为特征的骨髓增生性肿瘤的重叠特征[1]。存在转化为急性髓系白血病 (AML) 的易感性,称为原始细胞转化的 CMML (CMML-BT) [2, 3]。低甲基化剂 (HMA) 是 FDA 唯一批准的 CMML 疗法,但在延长总生存期 (OS) 和阻止疾病发展方面尚未确定疗效 [4,5,6]。为了提高反应率,维奈托克 (VEN) 已与 HMA 联合使用,从 AML 和 MDS 推断数据 [7, 8]。关于VEN对CMML和CMML-BT治疗HMA治疗的额外益处,单中心提供了不同的结果[9,10,11],但这些研究缺乏对照队列,并且受到每种治疗环境和疾病类别中评估的患者样本量小的限制。


为了阐明前期 HMA + VEN 在 CMML 和 CMML-BT 患者中的作用,我们进行了一项多中心回顾性队列研究,利用单独接受 HMA 治疗的患者的倾向评分匹配 (PSM) 队列。
