Brief Summary:

Acute 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.

Study Type : Observational
Actual Enrollment : 1067 participants
Observational Model: Cohort
Time Perspective: Retrospective
Official Title: Transfusion Dependency at Diagnosis and Transfusion Intensity During Initial Chemotherapy Are Associated With Poorer Outcomes in Adult Acute Myeloid Leukaemia
Study Start Date : January 2014
Actual Primary Completion Date : December 2014
Actual Study Completion Date : July 2015

Primary Outcome Measures :
  1. Overall survival (OS) [ Time Frame: Date of last contact if alive (up to 11 months) ]
    Overall survival (OS) is defined as the time elapsed between induction chemotherapy regimen and death for any cause. Patients not known to have this event are censored on the date they were last examined

Secondary Outcome Measures :
  1. Complete remission (CR) rate [ Time Frame: up to 11 months ]
    Response to induction therapy was assessed after one or two courses of chemotherapy (Between day 28 and day 35 of each course of chemotherapy). CR was defined according to standard criteria as less than 5 % blasts in bone marrow aspirates with evidence of maturation of cell lines and restoration of peripheral blood counts.

  2. Number of blood products for each type of administration [ Time Frame: Duration of study (11 months) ]

    Transfusion of a single unit of packed red blood cell (PRBC) or one whole-blood-derived platelet concentrate (PC) or platelets collected by apheresis (PA).

    Prophylactic transfusions were consistently given at morning platelet counts of <20×109/l and haemoglobin level <80 g/l. Patients requiring platelets were transfused with PC (PCs pooled from several units with 0.7 to 1×1011 platelets/10 kg of weight). Blood products were leukoreduced through discarding the buffy coat and administered through a standard blood filter but were not irradiated or routinely leukodepleted. Only patients planned to be allografted or autografted were transfused with irradiated transfusion products.
