During this latter stage, differentiation is apparently blocked, and the clonal, nonfunctional, proliferating blast cells accumulate to cause a clinical disease similar to acute leukaemia. Removal of leukaemia inhibitory factor from the medium causes these cells to differentiate into embryoid bodies. Malignant blood disorders with associated anaemia, such as myelodysplasia and leukaemia, become more frequent with advancing age. He fought bravely against his leukaemia and tried as long as possible to maintain his scientific activity. Some of the earliest were antifolates, chemically modified to increase their effectiveness in treating childhood leukaemias.

An example might be a cluster of leukaemia cases near a nuclear power plant. Median survival for early-stage chronic lymphatic leukaemia and indolent follicular lymphomas is in the order of 10 years. An example of this is the occurrence of acute myeloid leukaemia in patients with myelodysplasia. Every parent grieves for the death of their children from leukaemia. Risk factors in the remaining three patients were : chronic myelogenous leukaemia, immunosuppression for renal transplant, and hyperglycaemia induced by corticosteroid used for temporal arteritis. A replication-defective retroviral vector based on the murine leukaemia virus is genetically modified to encode the human c sequence. However, such an approach would be possible in a limited number of tumour types, such as leukaemia, where repeated sampling of the tumour was feasible. The median age of acute myeloid leukaemia at diagnosis is over 60 years. See all examples of leukaemia These examples are from corpora and from sources on the web.
