The leukocyte migration inhibition assay has been widely used as an in vitro test of cell mediated immunity to various substances. Using a leukemic cell line (RPMI 8402) as the source of antigen, we assayed leukocyte migration inhibition in seven children with acute lymphocytic leukemic (ALL), their family members (14 parents and 13 siblings), and 17 healthy adult controls. In six families, the patients showed stronger inhibition than their family members or controls. The patients differed significantly from their family members ( P = 0.003) and all other persons without leukemia ( P = 0.02). These results suggest that patients with ALL have developed a specific cellular immune reactivity to an antigen or antigens on leukemic cells, while their family members have not.
