Acute myeloid leukaemia is - like chronic myeloid leukaemia - a neoplasm of the granulocytes. The disease often causes an excess of granulocytes and a depletion of erythrocytes and platelets, which results in disturbed immunity, anaemia and impaired blood clotting. The illness prevails at older age and shows a preference for the male sex. There are familiarly traits and also some disorders predispose for getting leukaemia. The first symptoms are often rather unspecific. The therapy is based on cytostatics and radiation but more and more (re) implantation of bone marrow (or parts thereof) is performed, the marrow (components) being the patients own or donor material. Specific antibodies against the tumour cells are also increasingly used.
