Clinical Trial 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, we 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall survival (OS)	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	3 year OS	No
Primary	Overall survival (OS)	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	7 year OS	No
Secondary	Complete remission (CR) rate	Response to induction therapy was assessed after one or two courses 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	Up to 10 weeks	No
