Myelodysplastic Syndrome and Acute Myeloid Leukemia Related to PARP Inhibitors (MyeloRIB)
CancerAlthough PARP inhibitors (PARPi) have proved effective in treating many cancers, few patients receiving PARPi may experience rare but life-threatening adverse events such as myelodysplastic syndrome (MDS) and/or acute myeloid leukaemia (AML). Today, data about MDS/AML are scarce. The objective was to investigate reports of MDS/AML adverse events related to PARPi, including olaparib, rucaparib, niraparib, talazoparib and veliparib using the World Health Organization (WHO) and the French pharmacovigilance databases.

Comparison of Diagnostic Yield Among M-FISH, FISH Probe Panel and Conventional Cytogenetic Analysis...
Acute Myeloid LeukemiaConventional cytogenetic studies have been the gold standard for more than five decades for detecting genetic alterations that are greater than 10 Mb (mega base pairs) in size. Conventional cytogenetic studies have paved the way in identifying specific chromosomal aberrations associated with clinically and morphologically definitive subsets of hematological neoplasms. Fluorescence in situ hybridization (FISH) has become a reliable and rapid complementary test in targeting critical genetic events associated with diagnostics and prognosis in hematological neoplasms. In the current health care environment, which increasingly focuses on value and efficiency, it is critical for pathologists and clinicians to effectively navigate this environment and judiciously incorporate these high-complexity and expensive techniques into routine patient care. While conventional karyotyping provides a comprehensive view of the genome, FISH can detect cryptic or submicroscopic genetic abnormalities and identify recurrent genetic abnormalities in nondividing cells. As a consequence, it is commonly extrapolated that FISH will improve the sensitivity of detecting all genetic abnormalities compared with conventional karyotyping analysis. This assumption has then been translated in clinical practice to having clinicians and pathologists routinely ordering both conventional karyotyping and FISH studies in patients with hematological neoplasms. Depending on how comprehensive the FISH panel is, the cost for this testing may be quite expensive, and its additive value remains questionable. It is common practice for laboratories to use FISH panels in conjunction with karyotyping both in diagnostic specimens and during follow-up to monitor response to therapy. Multiplex FISH (M-FISH) represents one of the most significant developments in molecular cytogenetics of the past decade. In tumor and leukemia cytogenetics, two groups have been targeted by M-FISH to identify cryptic chromosome rearrangements not detectable by conventional cytogenetic studies: those with an apparently normal karyotype (suspected of harboring small rearrangements not detectable by conventional cytogenetics) and those with a complex aberrant karyotype (which are difficult to karyotype accurately due to the sheer number of aberrations).

Refractory AMLRelapsed Adult AML2 moreGilteritinib is available in early access in France through Temporary Authorisation of Use (or ATU program) since March 2019. The ATU program reflects a real-life treatment situation and the related clinical data would help to better understand the benefit/risk profile of gilteritinib and to better document gilteritinib efficacy and safety in patients who received midostaurine in First Line (1L) setting. The main objective is to describe gilteritinib effectiveness in FLT3 (Fms Related Tyrosine Kinase 3) -mutated AML patients in Refractory/Relapsed(R/R) situation treated in the context of early access program to gilteritinib in France through Temporary Authorisation of Use, the so-called ATU program, and the post ATU period from marketing authorisation to launch when reimbursement and price are published.

Diagnostic Platform to Perform Centralized and Standardized Rapid Molecular Diagnosis by Next Generation...
Acute Myeloid LeukemiaNGS studies will be done in stem cell leukemic population. The analysis of the samples to the diagnosis will be carried out using the 26 consensus genes: ASXL1 had, CBL, CEBPA, DNMT3A, EZH2, FLT3, GATA2, IDH1, IDH2, JAK2, KIT, KRAS, MPL, MLL, NPM1, NRAS, PTPN11, RUNX1, SETBP1, SF3B1, SRSF2, TET2, TP53, U2AF1, WT1. Regarding the 26 genes panel, it would have the advantage that the quantification of DNA from each sample will be carried out by fluorimetry using the AmpliSeq or TruSeq on Ion platforms torrent Proton or MySeq are handled in different laboratories. Using NGS techniques the investigator will detect the recurrently mutated genes in AML to establish the biological role of each mutation. The molecular characterization of the 700 samples which are estimated to pick up during the project will consist of massive sequencing of genes recurrently mutated in AML (ASXL1, had, CBL, CEBPA, DNMT3A, EZH2, FLT3, GATA2, IDH1, IDH2, JAK2, KIT, KRAS, MPL, MLL, NPM1, NRAS, PTPN11, RUNX1, SETBP1, SF3B1, SRSF2, TET2, TP53, U2AF1, WT1). Found mutations will be collated in the different databases of somatic variations to establish which of them could be classified as a driver or passenger.
Transfusion Dependency at Diagnosis and Transfusion Intensity During Initial Chemotherapy Are Associated...
Acute Myeloid LeukaemiaAcute myeloid leukaemia (AML) is a haematological malignant disease characterized by an uncontrolled proliferation of immature hematopoietic cells. Over the last two decades, clinical trials have demonstrated an improved response rate in younger adult AML. Aggressive induction plus more potent intensification programs with chemotherapy alone or chemotherapy plus stem cell transplantation (SCT) has improved treatment results. Advances in understanding disease biology, improvements in induction and consolidation program, and better supportive care have also all contributed. A number of clinical and laboratory characteristics influence the response to treatment and, thus, the survival of patients with AML. Among them, cytogenetic at diagnosis represents the most important prognostic variable. However, other factors may have a prognostic value and may influence patient's outcome. Anaemia and thrombocytopenia are cardinal manifestations of AML. Over the last decades, it has become apparent that the frequency of allogeneic blood transfusions can modify host immunity and clinical outcomes. Anaemia has long been recognized as an adverse prognostic factor in myelodysplastic syndrome (MDS), which represents a pre-leukemic disease. Red blood cell (RBC) transfusion need was identified as a strong and independent risk factor for survival in MDS, for which the presence and severity of anaemia were attributed to a clonally advanced and biologically more aggressive disease. Based on these data, the investigators retrospectively assessed the prognostic value of RBC and platelet transfusions at the time of diagnosis and the frequency of transfusions during the first induction course of chemotherapy in a large unselected group of patients with previously untreated AML.
Role of PTK-7 in Acute Myeloid Leukemias
Acute Myeloid LeukemiaThe pseudo tyrosine kinase receptor 7 (PTK7) is an orphan tyrosine kinase receptor assigned to the planar cell polarity pathway. PTK7 is expressed in normal myeloid progenitors and CD34(+) CD38(-) bone marrow cells in humans. It is also expressed in acute myeloid leukemia (AML) and is mostly assigned to granulocytic lineage differentiation. In AML, PTK7 seems to convey promigratory and antiapoptotic signals into the cell and represents an independent prognosis factor of survival in patients treated with induction chemotherapy. This study aims at: evaluating the impact of PTK7 expression on primary AML cells ex vivo evaluating the diagnostic and prognostic value of a soluble form of PTK7
