[Causes of death in chronic myeloid leukemia. Analysis of 109 patients].
The cause of death was revised in 109 cases of Ph'-positive chronic myelogenous leukaemia (CML) who died in a 15-year period. The median survival of the series, which included eight patients with initial criteria of blastic crisis, was 33.7 months (ranging between 2 and 192). Eight patients (7.3%) died during the chronic phase of the disease, 7 (6.4%) in the accelerated phase, and 94 (86.3%) in the blastic crisis. The cause of death in the chronic phase was frequently unrelated to CML (a second malignancy, cirrhosis of the liver, suicide, in four cases as opposed to infection, haemorrhage of hyperuricaemic renal failure in four others), but this was not so in the deaths occurred in the accelerated phase or blastic crisis. Thus, most of the deaths appearing in the accelerated phase were due to infection or haemorrhage, whereas in the blastic crisis they were mainly due to infection (54 of the 94 cases), followed by haemorrhage and leucostasis. All in all, these three complications were responsible for 94% of the deaths occurring in that evolutive phase of CML.
