| description | The MRC UKALL XA trial for patients aged 15 years and over with acute lymphoblastic leukaemia was designed to evaluate short blocks of intensive 'AML-style' treatment. Between 1985 and 1992, 618 eligible patients were entered into the trial. 450 patients were randomized to receive early intensification at 5 weeks, late intensification at 20 weeks, both, or neither. Unlike the concurrent children's trial, UKALL X, which was of similar design, UKALL XA does not demonstrate a clear benefit for intensification, although there was a significant reduction in the relapse risk due to the early block. The estimated increase in disease-free survival at 5 years was 2% with 95% confidence interval from 1% reduction to 5% increase. There may be a real difference between the effect of these treatments in adults and in children, but this result may be somewhat weakened by poorer compliance, with a greater proportion of adults not receiving the treatment arm to which they were randomized. |
