Acute leukaemia in children--French-American-British (FAB) classification and its relation to clinical features.

A retrospective study of 45 patients of acute leukaemia in children (15 years age), in relation to FAB classification, is presented. Acute lymphoblastic leukaemias (ALL) were commoner than acute myeloid leukaemias (AML), with an ALL:AML ratio of 4.63:1. Amongst ALL, L1 was the most frequent type (59%), followed by L2 (35%) and L3 (5.4%), respectively. FAB types M2, M3, M4 and M5 were diagnosed in 2 patients each. An analysis of clinical features in relation to FAB classification is also presented.
