Levels of CAF7 (CD98) expression correlate with the complete remission duration in childhood acute leukemia.

The levels of expression of the activation antigen CD98 were studied by mAB CAF7 in 51 newly diagnosed consecutive cases of childhood acute lymphoblastic leukemia aged from 1 to 13 years. The mean follow-up was 8 months. A wide range of CAF7 expression was observed, the highest mean fluorescence intensity exceeding the lowest by 20 times.
