Objective: To explore the efficacy and prognostic factors of hematopoietic stem cell transplantation (HSCT) for the treatment of patients with anaplastic large cell lymphoma (ALCL) . Methods: The clinical records of 33 ALCL patients after HSCT were collected and analyzed retrospectively to evaluate the rates of overall survival (OS) and recurrence after autologous (auto-HSCT) and allogeneic HSCT (allo-HSCT) and the factors influencing prognosis. Results: The median-age of this cohort of 33 ALCL cases at diagnosis was 31 (12-57) years old with a male/female ratio of 23/10, 24 cases (72.7%) were ALK(+) and 9 ones (27.3%) ALK(-). Of them, 25 patients (19 ALK(+) and 6 ALK(-)) underwent auto-HSCT and 8 cases (5 ALK(+) and 3ALK(-)) allo-HSCT with a median follow-up of 18.7 (4.0-150.0) months. Disease states before HSCT were as follows: only 6 patients achieved CR status and received auto-HSCT, 16 patients achieved PR (14 cases by auto-HSCT and 2 ones allo-HSCT) , the rest 11 cases were refractory/relapse (5 cases by auto-HSCT and 6 ones allo-HSCT) . There were 7 cases died of disease progression (5 after auto-HSCT and 2 allo-HSCT) and 5 cases treatment-related mortality (TRM) (2 after auto-HSCT and 3 allo-HSCT) , TRM of two groups were 8.0% and 37.5%, respectively. Both the median progression-free survival (PFS) and OS were 15 months after auto-HSCT, the median PFS and OS after allo-HSCT were 3.7 (1.0-90.0) and 4.6 (1.0-90.0) months, respectively. There was no statistically significant difference in terms of survival curves between the two groups (OS and PFS, P=0.247 and P=0.317) . The 2-year OS rates in auto-HSCT and allo-HSCT groups were 72% and 50%, respectively. The 5-year OS rates in auto-HSCT and allo-HSCT groups were 36% and 25%, respectively. Conclusion: ALCL treated by chemotherapy produced high rates of overall and complete responses. Chemotherapy followed by auto-HSCT remained to be good choice for patients with poor prognostic factors. High-risk patients should be considered more beneficial from allo-HSCT.
目的： 探讨造血干细胞移植治疗间变大细胞淋巴瘤（ALCL）的疗效及预后。 方法： 回顾性分析全国八家三甲医院2005年1月至2017年12月收治的33例接受造血干细胞移植（HSCT）的ALCL患者临床资料，评价自体造血干细胞移植（auto-HSCT）和异基因造血干细胞移植（allo-HSCT）治疗ALCL的生存率、复发率和影响预后的相关因素。 结果： 33例接受HSCT的ALCL患者的中位发病年龄为31（12~57）岁，男23例，女10例，间变性淋巴瘤激酶阳性（ALK(+)）和阴性（ALK(-)）分别为24例（72.7%）和9例（27.3%）。25例患者接受auto-HSCT（ALK(+)患者19例，ALK(-)患者6例），8例患者接受allo-HSCT（ALK(+)患者5例，ALK(-)患者3例）。移植后中位随访时间18.7（4.0~150.0）个月。移植前疾病缓解状态：完全缓解6例（均行auto-HSCT），部分缓解16例（auto-HSCT组14例，allo-HSCT组2例），复发难治11例（auto-HSCT组5例，allo-HSCT组6例）。疾病进展死亡7例，其中auto-HSCT组5例（20.0%），allo-HSCT组2例（25.0%）。移植相关死亡（TRM）5例，其中auto-HSCT组2例（8.0%），allo-HSCT组3例（37.5%）。auto-HSCT后中位无进展生存（PFS）和总生存（OS）时间均为15个月，allo-HSCT后中位PFS时间为3.7（1.0~90.0）个月，中位OS时间为4.6（1.0~90.0）个月，两组生存曲线差异无统计学意义（OS及PFS P值分别为0.247和0.317）。auto-HSCT和allo-HSCT组的2年OS率分别为72%和50%，5年OS率分别为36%和25%。 结论： ALCL化疗反应率高，有不良预后因素的情况下化疗后序贯auto-HSCT为重要治疗措施，高危患者或可从allo-HSCT中获益。.
