Acute Lymphoblastic Leukemia Risk Classification. Identify criteria by which we classify acute leukemias and how the current WHO classifications differ from the previous FAB classifications. Using the previous analyses and emerging data from other studies a classification system was developed and implemented as COG AALL03B1 Classification of Acute Lymphoblastic Leukemia. Developing a risk-group classification guide may help doctors assign patients with newly diagnosed acute lymphoblastic leukemia to treatment clinical trials. Classification of acute lymphocytic leukemia Different types of acute lymphocytic leukemia or acute lymphoblastic leukemia ALL start from different types of lymphocytes.
In the 1970s a group of French American and British FAB leukemia experts divided ALL into 3 subtypes L1 L2 and L3 based on the way the leukemia. 35 The algorithm uses a number of biologic markers some of which are determined at each COG center and others at central COG laboratories. Differentiate between acute lymphoblastic leukemia ALL and acute myeloid leukemia AML regarding causes patient populations symptoms and prognostic factors. The more uniform approach to risk-based treatment assignment and to collection of specific prognostic factors should increase the efficiency of future ALL clinical research. Risk classification at the time of diagnosis differentially affects the level of residual disease in children with B-precursor acute lymphoblastic leukemia after completion of therapy. Acute Lymphoblastic Leukemia ALL spreads out in childrens bodies rapidly and takes the life within a few weeks.
The more uniform approach to risk-based treatment assignment and to collection of specific prognostic factors should increase the efficiency of future ALL clinical research.

Cooperative mutations involved in cell differentiation cell cycle regulation tumor suppression drug responsiveness and apoptosis have also been identified in many cases. Acute lymphoblastic leukemia is a heterogeneous disease with individual leukemia subtypes differing in their response to chemotherapy.
