Summary Between June 1977 and July 1983 51 patients with Ph 1 ‐positive chronic granulocytic leukaemia (CGL) in transformation were treated either by chemotherapy or by chemoradiotherapy followed by autografting with haemopoietic stem cells collected from their peripheral blood at the time of diagnosis. Forty‐eight patients were restored to a second chronic phase. The median duration of survival after autografting was 26 weeks (range 2‐152 weeks). Twenty‐one patients with relatively long durations of second chronic phase were treated again by autografting as consolidation or when transformation recurred; this selected group of patients survived longer than the 30 patients treated by autografting only once (medians 52 v. 13 weeks respectively, P<0‐01). There was no significant influence of the patients’ age, splenectomy status, type of transformation, treatment pre‐autograft or number of nucleated cells autografted on the duration of survival. Three patients treated in myeloid blastic transformation were restored to partially Phnegative haemopoiesis. We conclude that this approach to the management of CGL in transformation can offer benefit for a minority of patients and that further chemotherapy and autografting for patients still in second chronic phase may be valuable.
