Abbreviations: SS (super sensitivity), sensitive to all four drugs (Dex, Pred, ASP, VCR); IS (intermediate sensitivity), sensitive to two or three of the four drugs; RR (relative resistance), sensitive to one or none of the four drugs; CCR, continuous complete remission; IF/e.rel, induction failure or relapse within 180 days of diagnosis; Late rel, relapse 181 or more days after diagnosis.
Two patients excluded from this analysis because they died of infection within 4 weeks of diagnosis.
