Factors affecting survival in White and Asian children with acute lymphoblastic leukaemia.

Some studies suggest that Asian children with leukaemia have a worse outcome than Whites. Survival of Asians with ALL treated at the Birmingham Children's Hospital from 1975 to 1994 was the same as that of Whites, despite their greater deprivation and poorer nutrition. For one 5-year period (1980-1984) Asians had significantly poorer survival, even after adjustment for prognostic factors. Poor treatment compliance during that period may have contributed to this difference.
