Prevalence and clinical outcome of Philadelphia-like acute lymphoblastic leukemia: A systematic review and meta-analysis

The presence of Philadelphia (Ph)-like ALL among patients with acute lymphoblastic leukemia (ALL) may indicate a poor prognosis similar to Philadelphia positive (Ph+) ALL although the data are still inconclusive and the prevalence of Ph-like ALL varied considerably across the studies.

Abstract The development of chimeric antigen receptor (CAR) T-cell therapy for select hematological malignancies represents one of the most remarkable therapeutic advances in the past decade. Currently, CD19-targeted CAR T-cell therapy is approved for relapsed/refractory diffuse large B cell lymphoma and acute lymphoblastic leukemia. However, there is significant interest in the application of CAR T-cell therapy to other hematological malignancies, including multiple myeloma, where the current focus is on the development of B cell maturation antigen-directed CAR T-cell therapy. Despite the successes achieved to da...

ConclusionsFLT3 mutation was not common in Chinese ALL patients. Age of onset, platelet counts and transplant status rather than FLT3 mutations were independent prognostic variables for ALL cases on OS in our cohort. In spite of small sample size, ETP-ALL may indicate a comparable higher FLT3-mutant rate. Since ETP-ALL has been identified as high-risk subgroup, these data warrant clinical studies with the implementation of FLT3 inhibitors in addition to early allogeneic hematopoietic stem cell transplantation for FLT3 mutant ETP-ALL.

Preclinical studies suggest that T-ALL cells are sensitive to BCL2 inhibition. Clinical activity of venetocla...

Activating mutations in FLT3 are frequent in acute myeloid leukemia (AML) and have important prognostic and therapeutic implications. Meanwhile, FLT3 aberrations have been detected in a smaller fraction of acute lymphoblastic leukemia (ALL), and their prognostic value are not well established. Therefore, we assessed the FLT3 mutation in Chinese adolescent and adult ALL patients.

Combination therapies including venetoclax were administered to 13 patients with relapsed/refractory T-ALL at our institution. Marrow responses were achieved in 60% of evaluable patients and 2 patients with early T-cell precursor (ETP) ALL remain alive in remission. Venetoclax combination therapies are safe and myelosuppression was the main adverse event observed with the addition of this drug.

This study aimed to analyze the role of postoperative treatment for BC in the development of subsequent HM. Using the French National Health Data System, we examined the HM risks in patients diagnosed with an incident primary breast cancer between 2007 and 2015, who underwent surgery as first-line treatment for BC. Main outcomes were acute myeloid leukemia (AML), Myelodysplastic syndrome (MDS), myeloproliferative neoplasms (MPNs), multiple myeloma (MM), Hodgkin’s lymphoma or non-Hodgkin’s lymphoma (HL/NHL), and acute lymphoblastic leukemia or lymphocytic lymphoma (ALL/LL). Analyses were censored at HM o...

Auer rods were first described in the cytoplasm of leukemia blasts by John Auer in 1906. Auer rods are commonly seen in myeloid progenitors, and serve as a diagnostic morphological feature of acute myeloid leukemia (AML) [1]. The differential diagnosis of hematopoietic neoplasms relies on the detection of cytoplasmic inclusions resembling Auer rods. Auer rod-like inclusions have been described in multiple myeloma [2], prolymphocytic leukemia (PLL) [3], B-cell acute lymphoblastic leukemia [4], chronic lymphocytic leukemia [4], splenic lymphoma [5] and nodal marginal zone lymphoma [6], which are quite distinct from the needl...
