Leukaemia Flashcards
what are the 4 types of leukaemia?
acute myeloid leukaemia
acute lymphoid leukaemia
chronic myeloid leukaemia
chronic lymphoid leukaemia
what is the difference between chronic and acute leukaemia?
acute = precursor cells, more aggressive cancer (malignant manner) chronic = mature cells, less aggressive cancer (benign manner)
what is the most common cancer in the 15-24 y/o age group?
leukaemia
in what age group is leukaemia the most common cause of death from cancer?
1 - 34 y/o
what is leukaemia?
cancer of the cells in blood
proliferation of partially developed blood cells (WBC, RBC, platelets)
which cells are affected in acute leukaemia?
proliferation of precursor cells (blast cells) in bone marrow leads to disrupted development of healthy WBC, RBC and platelets
what is a major risk factor for acute leukaemia?
Down’s syndrome
what are some clinical features of acute leukaemia?
abrupt onset, fast progression fatigue (anaemia) easy bleeding (thrombocytopenia) increased infections (leukopenia) pain and tender bones pain in lymph nodes abdo fullness (hepatosplenomegaly)
which cells are affected in chronic leukaemia?
proliferation of premature cells (granulocytes, monocytes, premature b cells) in bone marrow leads to disrupted development of healthy WBC, RBC and platelets
what are some clinical features of chronic leukaemia?
slow onset, slow progression fatigue (anaemia) easy bleeding (thrombocytopenia) increased infections (leukopenia) pain and tender bones pain in lymph nodes abdo fullness (hepatosplenomegaly)
how is leukaemia diagnosed?
peripheral blood smear, and bone marrow biopsy
which type of leukaemia is most common in children?
acute lymphoid leukaemia
which type of leukaemia is most common in adults?
acute myeloid leukaemia
