Cell markers and acute leukaemia subtypes in Chile.

A panel of monoclonal antibodies were used to define acute myeloblastic leukaemia (AML) and acute lymphoblastic leukaemia (ALL) with its different subgroups. Thirty-three patients were studied in a period of one year. ALL was diagnosed in 80% of the children and 20% of the adults. AML was present in 22% of the children and 78% of adults. In children, only one of seven was common ALL, three of seven were T-ALL and three of seven were B-ALL. Five of 12 were unclassifiable (U-ALL). In adults the 4 ALL were U-ALL.
