Brief summary
Create a network of institutions in developing countries that will perform AML diagnosis, risk classification, treatment, supportive care and follow-up evaluation according to a common protocol and will register data using common clinical research forms (CRFs) in a single database and available on the internet.
Detailed description
1. Compare overall survival and disease-free survival of patients with acute myeloid leukemia classified according the European LeukemiaNet treated in participating South American hospitals with the results reported in developed countries. 2. Compare overall survival and disease-free survival of patients with AML low or intermediate risk treated with two cycles of cytarabine in intermediate dose versus one cytarabine cycle at the same dose followed by autologous SCT as consolidation. The risk will be established according to the classification of the European LeukemiaNet. 3. Create a network of institutions in developing countries that will perform AML diagnosis, risk classification, treatment, supportive care and follow-up evaluation according to a common protocol and will register data using common clinical research forms (CRFs) in a single database and available on the internet 4. Using National Reference Laboratories, provide cytogenetic and molecular methods for all institutions participating in the network, thus allowing rapid diagnosis and risk stratification of AML cases according to the European LeukemiaNet structure; 5. Develop a method of assessing minimal residual disease based on flow cytometry adapted to local resources and capable of guiding therapeutic decisions; 6. Determine the time interval between: a) diagnosis and risk group determination; b) the first cycle of consolidation chemotherapy and autologous hematopoietic stem cells infusion; 7. Determine the frequency and etiologic agent of infections associated with treatment, the number and average duration of hospitalization due to episodes of neutropenia; 8. Create a bank of samples of bone marrow from AML patients at different times of treatment; 9. Determine the disease-free survival and the cumulative incidence rate of relapse and non-relapse mortality and compare them between chemotherapy alone and chemotherapy plus autologous SCT cohorts.
