TL;DR
This study evaluates the effectiveness and safety of the PEMD treatment regimen for newly diagnosed early-stage non-upper respiratory digestive tract or advanced extranodal NK/T-cell lymphoma patients.
Contribution
The study provides new evidence on the efficacy and safety of the PEMD regimen for a specific subset of NK/T-cell lymphoma patients.
Findings
The overall response rate was 52.7%, with 2-year and 4-year PFS rates of 34.2% and 25.5%, respectively.
ECOG performance score >1 was identified as an independent risk factor for PFS.
Anemia was the most common adverse effect, occurring in 81.6% of patients.
Abstract
探讨PEMD(培门冬酶+依托泊苷+甲氨蝶呤+地塞米松)方案治疗初治早期非上呼吸道消化道或晚期结外NK/T细胞淋巴瘤(ENKTL)患者的疗效及安全性。 回顾性分析纳入2016年1月至2022年12月于南京医科大学第一附属医院血液科诊断为初治早期非上呼吸道消化道或晚期ENKTL,且接受PEMD方案诱导化疗的38例患者。采用Kaplan-Meier法计算无进展生存(PFS)和总生存(OS)率,采用Log-rank检验比较组间生存差异,进行生存和预后因素分析。 男30例(78.9%),女8例(21.1%);中位年龄48(26~72)岁。7例(18.4%)年龄>60岁,7例(18.4%)美国东部肿瘤协作组(ECOG)体能评分>1分,20例(52.6%)LDH水平升高,37例(97.4%)出现鼻部以外的结外组织受累,37例(97.4%)Ann Arbor分期为Ⅲ~Ⅳ期。患者中位治疗5(1~6)个周期,中位随访时间为60(24~101)个月。所有患者治疗结束时的总有效率为52.7%。2年和4年的PFS率分别为34.2%(95% CI 22.0%~53.2%)和25.5%(95% CI 14.7%~44.4%),2年及4年OS率分别为50.0%(95% CI 36.4%~68.7%)及45.5%(95% CI 31.4%~65.7%)。ECOG体能评分>1分[HR=3.711(95% CI 1.494~9.218),P=0.005]、骨髓浸润[HR=2.251(95% CI 1.026~4.938,P=0.043)]及PINK-E评分3~5分[HR=2.350(95% CI 1.009~5.476),P=0.048]为PFS的危险因素,多因素分析ECOG体能评分>1分为PFS的独立危险因素[HR=7.971(95% CI 2.222~28.591),P=0.001]。安全性评估显示,主要的不良反应为贫血(31例,81.6%)。 PEMD方案对治疗初治早期非上呼吸道消化道或晚期ENKTL患者是安全有效的。
