[Microangiopathic haemolytic anaemia as a complication of mitomycin C treatment (author's transl)].

Microangiopathic haemolytic anaemia developed in 5 (out of 14) patients treated with mitomycin C combinations, having received 4 or more treatment cycles. This finding necessitates restricted use of broad and longterm use of mitomycin C, particularly in view of the occasionally fatal outcome of this toxic complication. Adjuvant treatment with mitomycin C does not appear acceptable any longer. Patients treated with mitomycin C should be monitored carefully for occurrence of schistocytosis and platelet deficiency as very early signs of microangiopathic haemolytic anaemia.
