Although the chance of cure for children with acute lymphoblastic leukaemia (ALL) is high, their outlook with subsequent relapse is poor. Bone marrow transplantation may be an option for some, but the need for intensive reinduction chemotherapy regimens remains the best hope for effecting cure in the majority of relapsed children. The authors report the experience of using an intensive chemotherapy protocol (Memorial Sloan-Kettering-New York II Protocol, MSK-NY-II) in a series of relapsed children with ALL. Thirty children presenting to the Royal Alexandra Hospital for Children, Sydney, in their first relapse of ALL were treated according to a modification of the original MSK-NY-II protocol. Three children (10%) died during induction therapy, two from overwhelming Gram-negative sepsis, and one from intracerebral haemorrhage. Of 27 children completing induction, two children failed to enter remission; however, both had planned deviations from the protocol. Infectious complications were prominent with a total of 55 admissions for febrile neutropenic episodes. Eight children required the support of the intensive care unit for infectious complications. A total of 36 microbiological isolates were obtained from the patients during induction therapy. Ten bone marrow transplant procedures have been subsequently performed in these children, of whom five are alive and disease free at the time of writing. The MSK-NY-II protocol is an intensive regimen but with encouraging early remission rates in relapsed childhood ALL. Early sepsis in previously immunosuppressed children is an important cause of induction death.
