Abstract
Acute promyelocytic leukemia is a rare form of acute myeloid leukemia in which immature promyelocytes abnormally proliferate in the bone marrow. In most cases, the disease is characterised by the translocation t(15;17) (q24;q21), which causes the formation of PML::RARA, an oncogenic fusion protein responsible for blocking myeloid differentiation and survival advantage. Here, we present a case of acute promyelocytic leukemia with two unusual features: basophilic differentiation and a three-way translocation involving chromosomes 12, 15 and 17. In the few cases reported, basophilic differentiation was associated with a poor prognosis. In contrast, our patient responded promptly to the standard treatment with all-trans-retinoic acid (ATRA) and arsenic trioxide (ATO) and obtained complete remission. To our knowledge, this is the first report of basophilic acute promyelocytic leukemia with the three-way translocation t(12;17;15) (p13; q24;q21).

Abstract
B-cell precursor acute lymphoblastic leukemia (BCP-ALL) is a heterogeneous malignancy and consists of several genetic abnormalities. Some of these abnormalities are used in clinics for risk calculation and treatment decisions. Patients with ZNF384 rearrangements had a distinct expression profile regardless of their diagnosis, BCP-ALL or mixed phenotype acute leukemia (MPAL) and defined as a new subtype of ALL. In this study, we screened 42 MPAL and 91 BCP-ALL patients for the most common ZNF384 fusions; ZNF384::TCF3, ZNF384::EP300 and ZNF384::TAF15 by using PCR. We identified ZNF384 fusions in 9.5% of MPAL and 7.6% of BCP-ALL. A novel breakpoint was identified in ZNF384::TCF3 fusion in one BCP-ALL patient. T-myeloid MPAL patients showed significantly lower ZNF384 expression compared to lymphoid groups. Patients with ZNF384r had intermediate survival rates based on other subtypes. Prognostic and patient-specific treatment evaluation of ZNF384 fusions in both ALL and MPAL might help to improve risk characterization of patients.

Abstract
Background Biphenotypic acute leukemia (BAL), or mixed-phenotype acute leukemia (MPAL) represents a rare subgroup of acute leukemia which co-expresses markers for either more than one lineage in a homogenous blast population or the coexistence of two blast populations of different lineages. Proper diagnosis and classification of BAL are extremely important for patients' outcome since BAL usually has a poor prognosis. Purpose The objective of this study was to identify the incidence of biphenotypic acute leukemia, their clinical characteristics and outcome of BAL patients with the chemotherapy treatment and Hematopoietic Stem Cell Transplantation (HSCT) after initial complete remission. Patients and methods Ten cases of biphenotypic acute leukemia were analyzed for their clinical characteristics, immunological phenotypes, chemotherapy methods for induction initial complete remission and outcome data, including induction chemotherapy, complete remission (CR) and the overall survival time, relapse and death. This study was an observational, retrospective, and descriptive study of the clinical aspects of BAL. Cytogenetics and fusion genes analysis were also done with bone marrow samples using G-banding analysis and karyotyped according to the International System for Human Cytogenetic Nomenclature. The fusion genes' mutational status was determined by real-time PCR (RT-PCR). Gene mutation analyses were conducted with next-generation sequencing method. Results Among 10 BAL patients, 4 cases carried B/Myeloid phenotype, 4 cases carried T/Myeloid phenotype and 2 cases carried T/B phenotype. Cytogenetic analysis showed that 3 of the 10 cases had clonal abnormalities. Of the four cases of fusion gene aberration, two patients had RUNX1 gene mutation, one patient had BCR/ABL fusion gene mutation, and one patient had JAK1, JAK3, FBXW7 mutation. Overall, 5 of 8 (62.5%) BAL patients with chemotherapy achieved complete remission (CR) after their initial induction therapy. In the AML-directed therapy group, 1 of 2 (50%) patients achieved CR. Meanwhile, 4 of 6 (66.7%) patients achieved CR after ALL-directed induction chemotherapy. Two patients received Hematopoietic Stem Cell Transplantation (HSCT) after initial CRs, one patient died two months after transplantation due to pulmonary infection, and another patient is still alive. With an average of 14.3 (4.0-42.0) months' follow-ups, the median survival time was 7 months. Although patients achieved CR after initial chemotherapy, the relapse rate was very high and the CR rate after relapse was very low. Conclusion Our results confirmed that BAL is a rare malignancy with a very poor prognosis. Patients with ALL-directed chemotherapy achieved a better CR rate compared to those with AML-directed chemotherapy. Patients should receive HSCT after initial CR whenever it is possible.

Together, our findings reveal a role of TAF1 in leukemogenesis and identify TAF1 as a potential therapeutic target for AE-expressing leukemia.

Together, our findings reveal a role of TAF1 in leukemogenesis and identify TAF1 as a potential therapeutic target for AE-expressing leukemia. AML1-ETO is a fusion protein in which acetylation of lysine-43 is critical to leukemogenesis. Here, they show that TAF1 is required for AML1-ETO mediated gene expression such that it binds to acetylated AML1-ETO to facilitate the association of AML1-ETO with chromatin, and consequently, promotes leukemic self-renewal.

PHF6 and DNMT3A mutations are enriched in distinct subgroups of mixed phenotype acute leukemia with T-lineage differentiation. Blood Adv 2019; 2:3526-3539. [PMID: 30530780 DOI: 10.1182/bloodadvances.2018023531] [Citation(s) in RCA: 37] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2018] [Accepted: 11/08/2018] [Indexed: 12/26/2022] Open
Abstract
The genetic aberrations that drive mixed phenotype acute leukemia (MPAL) remain largely unknown, with the exception of a small subset of MPALs harboring BCR -ABL1 and MLL translocations. We performed clinicopathologic and genetic evaluation of 52 presumptive MPAL cases at Memorial Sloan Kettering Cancer Center. Only 29 out of 52 (56%) cases were confirmed to be bona fide MPAL according to the 2016 World Heath Organization classification. We identified PHF6 and DNMT3A mutations as the most common recurrent mutations in MPAL, each occurring in 6 out of 26 (23%) cases. These mutations are mutually exclusive of each other and BCR-ABL1/MLL translocations. PHF6- and DNMT3A-mutated MPAL showed marked predilection for T-lineage differentiation (5/6 PHF6 mutated, 6/6 DNMT3A mutated). PHF6-mutated MPAL occurred in a younger patient cohort compared with DNMT3A-mutated cases (median age, 27 years vs 61 years, P < .01). All 3 MPAL cases with both T- and B-lineage differentiation harbored PHF6 mutations. MPAL with T-lineage differentiation was associated with nodal or extramedullary involvement (9/15 [60%] vs 0, P = .001) and a higher relapse incidence (78% vs 22%, P = .017) compared with those without T-lineage differentiation. Sequencing studies on flow-cytometry-sorted populations demonstrated that PHF6 mutations are present in all blast compartments regardless of lineage differentiation with high variant allele frequency, implicating PHF6 as an early mutation in MPAL pathogenesis. In conclusion, PHF6 and DNMT3A mutations are the most common somatic alterations identified in MPAL and appear to define 2 distinct subgroups of MPAL with T-lineage differentiation with inferior outcomes.
