title: Prevention of meningeal  leukaemia and relapses by cranial irradiation and intrathecal MTX in acute lymphatic leukaemia.
abstract: Experience with CNS prophylaxis in 35 children with acute lymphatic leukaemia is reported. Before prophylactic irradiation of the skull was given the average survival time in 36 children was 2,8 (2,7) years. Menigeal leukaemia preceeded bone marrow relapse in 9 cases and followed relapse in a further 5 cases (39%). Between 1971 and 1973 Pinkel's treatment scheme VII was given to 35 children. This included prophylactic skull irradiation and intraspinal MTX injections. 29 children are still in their first remissions which range from 10 - 35 months in length. Meningeal leukaemia has not so far been observed, in this latter group.
