| Study objectives | To compare, in a randomised fashion the effect on remission rate, event-free survival and overall survival of i) receiving, both during induction and continuing treatment, either oral prednisolone or dexamethasone, ii) receiving, where appropriate and throughout treatment (apart from intensive blocks) either oral 6-mercaptopurine or 6-thioguanine. To assess the effect on event-free survival for all patients of a schedule concentrating on tight control of maintenance therapy. To collect data on i) thiopurine metabolites on serial blood samples to assess the adequacy of therapy and to compare the pharmacokinetics of 6-MP and 6-TG, and ii) the presence or absence of minimal residual disease in serial bone marrow samples to assess its clinical importance. Also, two randomisations will be carried forward from the previous trial (UKALL XI) until sufficient numbers have accrued to answer the questions to which they relate, so subsidiary objectives are i) to continue to study, in a prospective randomised manner, the effect of either two or three blocks of intensive therapy, and ii) to continue to study the effect of high-dose methotrexate or cranial irradiation for patients with presenting white counts in excess of 50 x 10^9/l. |
