Immunotherapy of human acute leukaemia

Abstract

Conclusions are difficult to draw. In the six studies of immunotherapy of AML discussed, all the three employing BCG and cells showed a prolongation of survival and the major contributing factor to this prolongation of survival was extension of life after relapse. In the three studies using BCG alone only one shows a beneficial effect, but some more time must be allowed to elapse before this can be concluded with confidence.
