Acute lymphoblastic leukemia includes T-cell acute lymphoblastic leukemia (T-ALL) and B-cell acute lymphoblastic leukemia (B-ALL). In children, T-ALL usually has a worse prognosis than B-ALL, although childhood T-ALL prognoses have improved remarkably. The varying outcomes among T-ALL cases suggest that an unrecognized biological heterogeneity may contribute to chemo-resistance. Deep exploration of T-lymphocyte development in recent years has found a subgroup of patients with a phenotype that resembles early T-cell precursor, which confers a much poorer prognosis than any other form of T-ALL. This novel subtype of T-ALL was called early T-cell precursor acute lymphoblastic leukemia (ETP-ALL). Flow cytometry data from T-ALL patients enrolled in Shanghai Children’s Medical Center between July 2002 and October 2010 were assessed according to Dr. Campana’s protocol. Among total 89 T-ALL cases, 74 cases had enough immunophenotype data available to differentiate between ETP (CD1a-, CD8-, CD5dim, at least one marker of stem cell or myeloid lineage) and non-ETP. From these 74 subjects, 12 ETP-ALL cases (16.2%) were identified. The event-free survival (EFS) rate at 66.8 months was 11.1%±10.1% for ETP-ALL and 57.6%±5.6% for non-ETP-ALL (P=0.003). The overall survival rates were 13.3%±11.0% for ETP-ALL and 64.7%±6.3% for non-ETP-ALL (P=0.002). Our findings demonstrate that early T-cell precursor leukemia is a very high-risk subtype of acute lymphoblastic leukemia with poor prognosis.

With the cure rate of childhood acute lymphoblastic leukemia (ALL) approaching 90%, further improvement in the treatment outcome and quality of life of patients will require better understanding of the mechanisms of drug resistance, identifying new leukemic cell genetic lesions that are amendable to available target therapy, and optimizing treatment based on host pharmacodynamics and pharmacogenomics. Deeper characterization of leukemic cell genetic abnormalities has discovered new subtypes of leukemia such as early T-cell precursor ALL and Philadelphia chromosome-like ALL, and identified many genomic alterations that have diagnostic, prognostic, or therapeutic implications. In this regard, several novel fusion transcripts are responsive to ABL tyrosine kinase inhibitors and potentially to JAK inhibitors. Genome-wide analyses have also unraveled the role of inherited cancer predisposing genes and small nucleotide polymorphisms of several genes in the development of childhood ALL. These advances promise to lead to more sophisticated personalized treatment strategies in the near future.

Mature T-cell lymphoid malignancies comprise a group of heterogeneous diseases that vary in clinicopathological features, biological behavior, treatment response, and prognosis. Bone marrow (BM) infiltration is more commonly present in mature T-cell lymphoid malignancies compared with their B-cell counterparts and hence important for differential diagnosis. In this study, clinical characteristics and prognostic factors were analyzed in 225 patients with mature T-cell lymphoid malignancies treated in a single institution. These included 29 cases of T-cell lymphoproliferative disorders (T-LPD, all with BM infiltration) and 196 cases of T-/natural-killer-cell lymphoma (T/NKCL, 56 with BM infiltration and 140 without BM infiltration). The estimated 5-year overall survival (OS) rates of T-LPD and T/NKCL were 96.6% and 37.3%, respectively. T-LPD patients were less likely to exhibit poor performance status, advanced disease stage, presence of B symptoms, or abnormal level of serum β-2 microglobulin. With similar pathological characteristics, T/NKCL patients with BM infiltration showed significantly lower response rates and shorter OS than those without BM infiltration (P = 0.0264 and P<0.0001, respectively). Multivariate analysis indicated that poor performance status, advanced disease stage, elevated serum lactate dehydrogenase level, and BM involvement were independent unfavorable prognostic factors. The Glasgow Prognostic Score may be more efficient than the International Prognostic Index in predicting disease outcome in T/NKCL. In conclusion, clinical characteristics may be useful in more effectively stratifying patients with mature T-cell lymphoid malignancies.

白血病复发仍是异基因造血干细胞移植(allogeneic hematopoietic stem cell transplantation,allo-HSCT)后急性B 淋巴细胞白血病(B cellacute lymphoblastic leukemia,B-ALL)治疗失败的主要原因。HSCT 后治疗伴有MRD 的B-ALL 的主要方法是供者淋巴细胞输注(donor lymphoblastic infusion,DLI)。在2014 年9 月至2018 年2 月期间,6 名患者均一次或多次输注了HSCT 供者提供的CD19 导向CAR 修饰T 细胞。无患者出现急性移植物抗宿主病(acute graft-versus-host disease,aGVHD),也无患者死于细胞因子释放综合征。

A CALLG2008 protocol was developed by the Chinese Acute Lymphoblastic Leukemia Cooperative Group for adult acute lymphoblastic leukemia (ALL). We retrospectively analyzed 153 newly diagnosed adult patients with Philadelphia chromosome (Ph)-positive ALL enrolled into imatinib (400 mg/d) plus CALLG2008 regimen between 2009 and 2015. The median age was 40 years (range, 18–68 years), with 81 (52.3%) males. The overall hematologic complete remission (CR) rate was 96.7% after induction. With a median follow-up of 24.2 months, the estimated 3-year overall survival (OS) and event-free survival (EFS) rates were 49.5% (95% confidence interval (CI): 38.5%–59.5%) and 49.2% (95% CI: 38.3%–59.2%), respectively. Fifty-eight (36 with haploidentical donor) patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) in first CR. Among the patients in CR1 after induction, both the 3-year OS and EFS were significantly better in the allo-HSCT group than in the without allo-HSCT group (73.2%, 95% CI: 58.3%–83.5% vs. 22.2%, 95% CI: 8.7%–39.6% and 66.5%, 95% CI: 50.7%–78.2% vs. 16.1%, 95% CI: 5.1%–32.7%, respectively). Multivariate analysis showed that allo-HSCT and achievement of major molecular response were associated with favorable OS or EFS independently. Interestingly, in the allo-HSCT cohort, the donor type (haploidentical versus matched donors) had no significant impact on EFS or OS. All these results suggested that imatinib plus CALLG2008 was an effective protocol for Ph-positive ALL. Haploidentical donors can also be a reasonable alternative expedient donor pool.
