Natural killer (NK)/T-cell lymphomas (NKTCLs) are rare, aggressive lymphomas prevalent in East Asia and South America. Despite improvements, largely due to asparaginase-based therapies, outcomes for advanced disease remain poor, and the role of autologous stem cell transplantation (auto-HCT) remains controversial. This study evaluated real-world outcomes of auto-HCT in NKTCL patients across Asia and Europe. We included 130 adult NKTCL patients undergoing auto-HCT between 2011 and 2022 using data from the European Society for Blood and Marrow Transplantation (EBMT) registry and South Korean registry data. Median age was 51.3 years; 66.9% were male. Most patients (95.1%) had an Eastern Cooperative Oncology Group (ECOG) score 0-1; 65.3% had Stage III-IV disease. One prior therapy line was reported in 53.1%, and ≥2 lines in 46.9%. Asparaginase-based regimens were used in 79.5% pretransplant. Responses at auto-HCT included complete (59.7%), partial (27.9%) remission, and stable/progressive disease (12.4%). Epstein-Barr virus (EBV)-DNA in the peripheral blood was reported in 37.3%. With a median follow-up of 4.6 years, 3-year overall survival (OS) and progression-free survival (PFS) were 63.8% and 47.6%. Relapse and NRM rates at 3 years were 46.7% and 5.7%. Patients in complete remission had improved 3-year OS (75.2%) compared to PR (52.8%) and stable/progressive disease (32.0%) (P = 0.007). Detectable EBV-DNA in the blood at auto-HCT was associated with poor outcomes (3-year OS: 26.7% vs. 78.1% in patients with undetectable EBV-DNA; P < 0.0001). Patients achieving complete remission and undetectable EBV-DNA in the blood before auto-HCT had a favorable survival, suggesting auto-HCT may be a treatment option in selected high-risk patients. This is the largest multinational cohort evaluating prognostic factors for auto-HCT for NKTCL.
自然杀伤(NK)/T细胞淋巴瘤(NKTCL)是一种罕见的侵袭性淋巴瘤,在东亚和南美洲较为常见。尽管在很大程度上由于基于天冬酰胺酶的治疗方法有所改善,但晚期疾病的治疗效果仍然很差,自体干细胞移植(auto-HCT)的作用仍存在争议。本研究评估了亚洲和欧洲NKTCL患者自体造血干细胞移植的实际疗效。我们纳入了2011年至2022年间接受自体造血干细胞移植的130例成年NKTCL患者,数据来自欧洲血液和骨髓移植学会(EBMT)登记处以及韩国登记处的数据。中位年龄为51.3岁;66.9%为男性。大多数患者(95.1%)东部肿瘤协作组(ECOG)评分为0-1;65.3%为III-IV期疾病。53.1%的患者曾接受过一线治疗,46.9%的患者接受过≥2线治疗。79.5%的患者在移植前使用了基于天冬酰胺酶的方案。自体造血干细胞移植后的缓解情况包括完全缓解(59.7%)、部分缓解(27.9%)以及病情稳定/进展(12.4%)。外周血中报告有EB病毒(EBV)-DNA的患者占37.3%。中位随访4.6年,3年总生存率(OS)和无进展生存率(PFS)分别为63.8%和47.6%。3年复发率和非复发死亡率分别为46.7%和5.7%。完全缓解的患者3年总生存率(75.2%)高于部分缓解(52.8%)和病情稳定/进展(32.0%)的患者(P = 0.007)。自体造血干细胞移植时血液中可检测到EBV-DNA与不良预后相关(3年总生存率:可检测到EBV-DNA的患者为26.7%,未检测到EBV-DNA的患者为78.1%;P < 0.0001)。在自体造血干细胞移植前达到完全缓解且血液中未检测到EBV-DNA的患者生存率良好,这表明自体造血干细胞移植可能是部分高危患者的一种治疗选择。这是评估NKTCL自体造血干细胞移植预后因素的最大规模跨国队列研究。
