title: [ALL-study series of Hamburg (author's transl)].
abstract: From 1971 through 1979 145 newly diagnosed patients with ALL have been treated within a series of consecutive studies. Study I corresponds to branch A of the 1972 DAL study. In the following studies the induction therapy has been escalated stepwise with the continuation therapy remaining mostly unchanged. Thereby the disease free survival rates increased from 75 to 94% after one year and from 32 to 60% after 4 years respectively. CNS-relapse mainly occurred during the second year of treatment. Their incidence rose from 5% to more than 10% in connection with a change in the radiation portal. Since another correction of the portals with special consideration of the paramedian lower border of the skull base no more CNS-relapses have been observed until now. The actual cooperative ALL-study follows a modified BFM-protocol with postponed asparaginase in hoping to achieve reduced initial morbidity and at least equal good survival times.
