HAEMATOLOGICAL
MALGINANCIES -
LEUKAEMIA
There are four main types of leukaemia shown below.
Acute leukaemia is characterised by a rapid increased in
immature blood cells, this proliferation leads to crowding and an
inability to produce healthy blood cells.
Chronic leukemia is characterised by the excessive buildup of
relatively mature, abnormal white blood cells.
Lymphoblastic/lymphocytic leukaemia affects lymphocytes.
Myeloid/myelogenous leukaemia affects cells which form
platelets & erythrocytes.
ACUTE LYMPHOBLASTIC
LEUKAEMIA (ALL)
Most common type of leukaemia in
children, but also common in over 65s.
Standard treatment includes chemo-
and radiotherapy.
Including Burkitt's lymphoma (t(8;14) -
leads to constitutive c-myc expression).
CHRONIC LYMPHOCYTIC
LEUKAEMIA (CLL)
Mostly affects over 55s, sometimes
young adults, almost never children.
It is incurable but treatable, with a 5-
year survival rate of 85%.
