Reports on the outcome of treatment in ALL in Asian (non-Caucasian) adults have been few, and published results compare very unfavourably with results of treatment from 'Western' centres. Seventy-four newly diagnosed Malaysian patients with ALL between the ages of 15 and 69 were treated from 1986 to 1990. The clinical features and prognostic factors were similar to those reported in 'Western' series. The chemotherapy protocol utilized was adapted from the one used by Hoelzer et al in the multicentre German study. The complete remission rate was 73%. The probability of continuous complete remission at 5 years was 29% with a median duration of remission of 15 months. This compares with Hoelzer's initial results of 77% CR rate and 35% CCR at 5 years. Patients with an initial white cell count of less than 30 x 10(9)/l at presentation were found to have a significantly better disease-free survival than those with a count of more than 30 x 10(9)/l (35 vs 22%, P = 0.026, univariate analysis). There was no difference in leukaemia-free survival according to age, sex, ethnic group, or immunophenotype. These results show that the use of moderately intensive chemotherapy protocols in Asian (non-Caucasian) patients achieves similar results to those used in Caucasians. We also showed that the difficulties in 'curing' approximately 70% of adult patient with ALL are universal.
