Leukaemia Flashcards
What is Leukaemia?
A cancer of the blood cells. The blood cells begin to grow before reaching maturity. This means that the ‘leukaemic’ or abnormal cells outnumber the normal blood cells
Leukaemia classification
MYELOID ORIGIN
LYMPHOID ORIGIN
Symptoms of leukaemia
Fevers, frequent infections
Night sweats
Fatigue (feeling tired or washed out), pallor, confusion, headaches, blurred vision, shortness of breath
Weight loss
Easy bleeding or bruising, gum bleeding
Less common - swellings, bone pain, other pain.
Diagnosis of leukaemia
Full blood count and blood film Biochemistry (kidney/liver function tests, haemolysis) Bone marrow biopsy Immunophenotyping and genetic analysis Chest x-ray Lumbar puncture
Treatment of leukaemia
Transfusions
Chemotherapy
Steroid therapy
Growth factors
Radiotherapy
Bone marrow/stem cell transplant
Chemotherapy for leukaemia
Kill leukaemia cells – intensive - tablets or injection.
Induction - first part. Several blocks each lasting a
few days with several weeks rest in between.
Transfusions
Red blood cells (from leukaemia and/or chemo)
Platelets
Plasma (only if bleeding or coagulopathy)
Radiotherapy of leukaemia
Kill any cells in the CNS that may have survived chemotherapy (blood/brain barrier).
May be given as a preventative treatment to the brain and spine
Bone marrow/stem cell transplant
Intensive chemotherapy +/- total body irradiation
Also kills healthy bone marrow cells including stem cells. To survive - a bone marrow or stem cell transplant is given.
Transplant is given like a transfusion.
Allogeneic (close relative e.g. brother or sister or an unrelated donor from bone marrow register) or autologous
Transplantation may fail due to
Graft failure
Graft versus host disease
Leukaemia relapse
Infection
