Survival of autografted CML patients — Cox regression analysis of survival. (A) Comparison between patients treated on protocols CY/GM/BM, MAC/G/PB, or CY/G/PB based on disease stage: ECP CML (diagnosed <1 year before transplantation and in CP), LCP CML (diagnosed >1 year before transplantation and in CP), and AP CML (diagnosed >1 year before transplantation and in CP or accelerated phase). (B) Comparison between patients transplanted at the University of Minnesota with IFN-γ–purged autologous marrow (1988 to 1994) and patients transplanted using primed BM or PB cells in protocols CY/GM/BM, MAC/G/PB, or CY/G/PB.
