Although lenalidomide plus dexamethasone (RD) is a therapeutic option for relapsed/refractory multiple myeloma (RRMM), limited real-world clinical data exist. The purpose of this study was to estimate efficacy and safety of RD in RRMM patients of the clinical practice. Data from patients at 25 university hospitals in South Korea between October 2009 and December 2016 were collected retrospectively. We report the effectiveness and safety of RD in 546 RRMM patients in routine clinical practice in South Korea. Patients (median age, 65 years) typically received median 7 cycles of RD, and 184 (33.7%) patients were treated with 10 or more cycles of RD. Patients with renal impairment (CLCr < 40 mL/min; 10.4%), comorbid conditions (≥ 2; 12.0%), and poor performance status (≥ 2; 25.1%) were included. The overall response rate was 64.2%: complete response (13.1%), very good partial response (VGPR 19.9%). With median follow-up duration of 18.6 months, median PFS and OS were 11.2 months and 25.2 months, respectively. In multivariate analysis, less than 2 comorbid conditions, normal LDH, failed one chemotherapy prior to RD, and ≥ 10 cycles of RD therapy had significantly prolonged PFS (P = 0.007, P = 0.011, P = 0.007, and P < 0.001, respectively). Adverse events were acceptable. RD is effective and safe in real-life clinical practice, including patients with comorbidities. RD is an effective and safe treatment in a real clinical setting which includes patients with comorbidities. Early and continual use of RD treatment may improve RRMM survival outcomes.

来那度胺和地塞米松在复发/难治性多发性骨髓瘤患者中的有效性和安全性在现实生活中的临床实践:韩国多发性骨髓瘤工作组的一项研究(KMMWP-151研究)。

尽管来那度胺联合地塞米松(RD)是复发/难治性多发性骨髓瘤(RRMM)的治疗选择,但实际的临床数据有限。这项研究的目的是评估RDMM在RRMM患者中的临床疗效和安全性。回顾性收集了2009年10月至2016年12月间韩国25家大学医院患者的数据。我们在韩国的常规临床实践中报告了546 RRMM患者的RD有效性和安全性。患者(中位年龄为65岁)通常接受7个周期的RD治疗,其中184个(33.7%)患者接受了10个或更多周期的RD治疗。包括肾功能不全(CLCr <40 mL / min; 10.4%),合并症(≥2; 12.0%)和表现不佳(≥2; 25.1%)的患者。总体回应率为64.2%:完全缓解(13.1%),非常好的部分缓解(VGPR 19.9%)。中位随访时间为18.6个月,中位PFS和OS分别为11.2个月和25.2个月。在多变量分析中,少于2种合并症,LDH正常,在RD前一项化疗失败和RD治疗≥10周期的PFS显着延长(分别为P = 0.007,P = 0.011,P = 0.007和P <0.001 )。不良事件是可以接受的。RD在包括合并症患者在内的实际临床实践中是有效且安全的。在包括合并症患者在内的实际临床环境中,RD是一种有效且安全的治疗方法。早期和持续使用RD治疗可改善RRMM生存期。分别为2个月和25.2个月。在多变量分析中,少于2种合并症,LDH正常,在RD前一次化疗失败和RD治疗≥10周期的PFS显着延长(分别为P = 0.007,P = 0.011,P = 0.007和P <0.001 )。不良事件是可以接受的。RD在包括合并症患者在内的实际临床实践中是有效且安全的。在包括合并症患者在内的实际临床环境中,RD是一种有效且安全的治疗方法。早期和持续使用RD治疗可改善RRMM生存期。2个月和25.2个月。在多变量分析中,少于2种合并症,LDH正常,在RD前一项化疗失败和RD治疗≥10周期的PFS显着延长(分别为P = 0.007,P = 0.011,P = 0.007和P <0.001 )。不良事件是可以接受的。RD在包括合并症患者在内的实际临床实践中是有效且安全的。在包括合并症患者在内的实际临床环境中,RD是一种有效且安全的治疗方法。早期和持续使用RD治疗可改善RRMM生存期。不良事件是可以接受的。RD在包括合并症患者在内的实际临床实践中是有效且安全的。在包括合并症患者在内的实际临床环境中,RD是一种有效且安全的治疗方法。早期和持续使用RD治疗可改善RRMM生存期。不良事件是可以接受的。RD在包括合并症患者在内的实际临床实践中是有效且安全的。在包括合并症患者在内的实际临床环境中,RD是一种有效且安全的治疗方法。早期和持续使用RD治疗可改善RRMM生存期。
