Objective: To investigate the efficacy and predictors of autologous hematopoietic stem cell transplantation (auto-HSCT) in the treatment of T lymphoblastic lymphoma (T-LBL) . Methods: 41 patients with T-LBL who underwent auto-HSCT from April 2006 to July 2017 in the Department of Hematology, the First Affiliated Hospital of Soochow University and the Department of Lymphoma, Peking University Cancer Hospital were analyzed retrospectively. Results: ①Among 41 patients, there were 30 males and 11 females with median age of 24 (11-53) years old. According to the Ann Arbor staging, 33 (80.5%) patients were in stage Ⅲ/Ⅳ. 12 (29.3%) patients have mediastinal involvement, and 20 (48.8%) patients have bone marrow (BM) involvement. Before transplantation, there were 26 (63.4%) patients who achieved first complete remission (CR(1)) , the other 15 (36.6%) patients were in the non-CR(1) group, and there were 29 (70.7%) patients in the low-intermediate risk group (IPI<3 scores) , the other 12 (34.1%) patients were in the middle-high risk group (IPI≥3 scores) . ②The median follow-up was 29 (3-98) months. The 3-year overall survival (OS) and progression-free survival (PFS) for 41 patients were (64.3±8.2) % and (66.0±7.8) %, respectively. 3-year cumulative recurrence rate (CIR) was (30.7±7.4) %, and 3-year non-recurring mortality (NRM) was (4.8±4.6) %. ③The 3-year OS of the CR(1) group and the non-CR(1) group were (83.4±7.6) % and (38.9±12.9) % (P=0.010) , and the 3-year PFS of two groups were (83.8±7.4) % and (40.0±12.6) % (P=0.006) , respectively. The 3-year CIR of these two groups were (16.2±7.4) % and (53.3±12.9) % (P=0.015) , and the 3-year NRM were 0 and (14.3±13.2) % (P=0.157) , respectively. ④The 3-year OS of the IPI low-intermediate risk group and the high-intermediate risk group were (76.9±8.4) % and (35.7±15.2) % (P=0.014) and the 3-year PFS were (77.4±8.2) % and (40.0±14.6) (P=0.011) , respectively. The 3-year CIR of these two groups were (18.1±7.3) % and (60.0±14.6) % (P=0.006) , and the 3-year NRM were (5.6±5.4) % and 0 (P=0.683) , respectively. The OS and PFS of patients with low-intermediate risk group were significantly higher than the other group. Conclusion: Auto-HSCT could improve the survival of T-LBL. Pre-transplant status and IPI score are important predictors for survival T-LBL patients with auto-HSCT.
目的： 探讨自体造血干细胞移植（auto-HSCT）巩固治疗T淋巴母细胞淋巴瘤（T-LBL）的疗效及相关影响因素。 方法： 对2006年4月至2017年7月在苏州大学附属第一医院血液科和北京大学肿瘤医院淋巴瘤科接受auto-HSCT的41例T-LBL患者进行回顾性分析。 结果： ①41例T-LBL患者中，男30例，女11例，中位年龄24（11~53）岁，12例（29.3%）纵隔累及，20例（48.8%）骨髓累及，Ann Arbor分期Ⅲ期及以上33例（80.5%）；移植前疾病处于第1次完全缓解（CR(1)）期26例（63.4%），非CR(1)期15例（36.6%）；移植前国际预后指数（IPI）中低危组（<3分）29例（70.7%），中高危组（≥3分）12例（29.3%）。②移植后中位随访29（3~98）个月，全部41例患者的3年总生存（OS）率、无进展生存（PFS）率分别为（64.3±8.2）%、（66.0±7.8）%，3年累积复发率（CIR）为（30.7±7.4）%，3年非复发死亡率（NRM）为（4.8±4.6）%。③CR(1)组、非CR(1)组患者3年OS率分别为（83.4±7.6）%、（38.9±12.9）%（P=0.010），3年PFS率分别为（83.8±7.4）%、（40.0±12.6）%（P=0.006），3年CIR分别为（16.2±7.4）%、（53.3±12.9）%（P=0.015），3年NRM分别为0、（14.3±13.2）%（P=0.157）。④IPI中低危组、中高危组3年OS率分别为（76.9±8.4）%、（35.7±15.2）%（P=0.014），3年PFS率分别为（77.4±8.2）%、（40.0±14.6）%（P=0.011），3年CIR分别为（18.1±7.3）%、（60.0±14.6）%（P=0.006），3年NRM分别为（5.6±5.4）%、0（P=0.683）。 结论： auto-HSCT可显著改善T-LBL患者的预后，移植前疾病状态和IPI评分是影响auto-HSCT疗效的重要因素。.
