[Oncology blood transfusion and quality of life: review].

Blood transfusion's repercussions on quality of life are less well studied in cancer research, and rarer in palliative situation. It is necessary to look for studies dealing with anaemia to estimate its effects. In curative palliative situation, the situation is similar to that of curative stage patients. It is necessary landing quickly for anaemia to assure the patient's quality of life. Blood transfusion and more recently erythropoïesis-stimulating agents are effective treatments. In advanced palliative stage, transfusion improves symptoms (weakness and dyspnoea bound anaemia) and the patients' well being. The treatment choice must be individual and has to follow an ethical behaviour in respect with the legislation.
