Heralding Extramedullary Blast Crisis: Horner's Syndrome with Brachial Plexopathy in a Patient with Chronic Myelogenous Leukemia.

ABSTRACT: Chronic myelogenous leukemia (CML) blast crisis is an ominous clinical event that is challenging to treat. This can develop at extramedullary sites rarely and is defined as the infiltration of blasts outside the bone marrow irrespective of proliferation of blasts within the bone marrow. We aim to report an unusual clinical presentation characterized by Horner's syndrome, ipsilateral arm weakness, and cervical lymphadenopathy as the first signs of extramedullary blast crisis in a CML patient. To the best of our knowledge, the extramedullary locations involving the brachial plexus along with cervicothoracic paraspinal chloroma have not been previously reported in the literature.

Lineage-specific function of Engrailed-2 in the progression of chronic myelogenous leukemia to T cell blast crisis

Project description:Deregulations in transcription factors lead to abnormal development, like in leukaemias, where chromosomal abnormalities either create chimeric TFs or alter the expression of the existing ones. The characterization of the precise functions of the TFs that regulate blood formation is essential to understand how these mechanisms are altered in malignancies. We have found that Engrailed-2 becomes methylated in the progression to blast crises of T-cell phenotype in chronic myelogenous leukaemia (CML) in human samples. Subsequently we found that En2 is expressed during T-cell development in the mouse and in humans. Engrailed-2 plays an essential role in central nervous system development but it has not been shown to participate in haematopoiesis. Many TFs have been found to play essential functions both in nervous system and blood development, thus making En2 a likely candidate to be involved in haematopoiesis. We have studied haematopoiesis of wild-type vs. En2 knockout mice. To increase our understanding of the possible molecular role(s) of En2 during T cell development, we have compared by microarray analysis the gene expression patterns of En2-/- versus WT sorted DP thymocytes and also CD8+ splenocytes (the two populations in which we had detected En2 expression).

T cell Immune Escape in Blast Crisis Transformation of Chronic Myeloid Leukemia

Project description:Chronic myeloid leukemia (CML) may transform from a chronic phase (CP) into blast crisis (BC), which is often incurable. Herein, we report that miR-142 deficit acquired by T lymphocytes contributes to BC transformation by promoting immune escape. We observe that T cells of BC patients lack miR-142 and are fewer and exhausted compared with CP patients. Similarly, BC miR-142−/−/BCR/ABL+/+ mouse presents with T lymphopenia compared with the CP miR-142+/+/BCR/ABL+/+ mouse. In the BC mouse, miR-142 deficit impairs thymic differentiation of lymphoid-primed multipotent progenitors (LMPP) into mature T cells and redirects them toward myeloid lineage. The fewer mature T cells in the BC mouse are enriched with exhausted T effectors. MiR-142 deficit, driven by leukemic blasts-secreted inflammatory cytokines (i.e., IL-6), induces T cell hypofunction by preventing the metabolic reprogramming that allows activated T cells to thrive and expand. This ultimately results in an increase in T cell spontaneous apoptosis and BC immune escape. In fact, NSG mice transplanted with BC CML LSKs and miR-142 KO T cells had shorter survival than mice transplanted with BC CML LSKs and miR-142 wild-typewt T cells. Conversely, BC patient-derived xenograft (PDX) mice receiving autologous T cells and synthetic miR-142 lived longer than those receiving autologous T cells and scramble RNA. Combination of tyrosine kinase inhibitors (TKI) plus synthetic miR-142 and/or PD-1 antibody induced a prolonged survival compared to TKI alone, suggesting that harnessing the host immune system with synthetic miR-142 and immunocheckpoint inhibitors along with BCR/ABL inhibition may provide novel therapeutic opportunities.
