Measure Description:
AML is classified using the WHO classification system based upon a combination of morphology, immunophenotype, genetics, and clinical features. There are several broad groups and include:

Measure Description: Primary AML is a cancer that originates in the blood and bone marrow. AML affects a group of white blood cells called myeloid cells, which normally develop into the various types of mature blood cells, such as red blood cells, white blood cells and platelets. Secondary acute myeloid leukemia (s-AML) refers to a leukemic process: (1) evolving from prior myelodysplasia (MDS), myeloproliferative disorder (MPN), or aplastic anemia (AA) with or without treatment or (2) as a product of previous exposure to a proven leukemogenic chemotherapeutic agent (therapy-related AML [t-AML]).

Measure Description: ECOG performance status is used to describe a patient's level of functioning in terms of their ability to care for themselves, daily activity, and physical ability (walking, working, etc.). The scale ranges from 0 to 5: 0 = Fully active, no restrictions; 1 = Restricted activity but ambulatory, able to carry out work of a light nature; 2 = Ambulatory and capable of all self-care but unable to carry out work activities; 3 = Capable to only limited self-care, confined to bed or chair more than 50% of waking hours; 4 = Completely disabled, no self-care, confined to bed or chair; 5 = Dead.

More Information
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts
the PI's rights to discuss or publish trial results after the trial is completed.
Results from a center cannot be submitted for publication before results of multicenter study are published unless it is > 1 year since study completion. Then, Investigator can publish if manuscript is submitted to Celgene 60 days prior to submission. If Celgene decides publication would hinder drug development, Investigator must delay submission for up to 90 additional days. Investigator must delete confidential information before submission and defer publication to permit patent applications.
