Introduction The main treatment for acute myeloid leukaemia (AML) is chemotherapy, including targeted therapy where cancer drugs attack specific components of the leukaemia cells. This might be followed by a stem cell transplant. Surgery and radiation therapy may be used in special circumstances. New therapies are being developed and investigated every day. Several of these new drugs for the treatment of AML are described in this booklet. If you need specific advice or professional who is specialised have any questions about this in leukaemia, Dr Emmanouil treatment, please contact your Nikolousis. We are also grateful to medical team or Clinical Nurse a leukaemia patient, Julie Quigley, Specialist (CNS). for her valuable contribution as a reviewer.

The National Institute for Health and Care Excellence (NICE) issues recommendation guidelines based on the best available evidence of which drugs work and what their costs are. Decisions on which topics to develop guidelines on, and in what order, are based on suggestions by commissioners and professional organisations, and organisations for people using services, their families and carers. The final decision is made in conjunction with NHS England and the Department of Health and Public Health. Published guidelines are available on the NICE website at https:// www.nice.org.uk/guidance/ published?type=cg. Checks on whether a guideline needs updating is usually undertaken by NICE every two years and is always undertaken at least every four years from the date of guideline publication. A list of the guidance in the various stages of development with estimated completion dates are available on the NICE website at https:// www.nice.org.uk/guidance/ Helpline freephone 08088 010 444 7
