Haematological malignancies Flashcards
ALL
children
risk factor-down syndrome
overproduction of immature lymphocytes-> pancytopenia
blood film: blasts
CLL
elderly
overproduction of mature B lymphocytes
• 1/3$cured,$1/3$stay$the$
same,$1/3$worsen$
blood film=smear cells
large, rubbery, non-tender lymph nodes
AML
elderly
auer rods
CML, MPN can become AML
myeloid cells can’t differentiate beyond blast stage
CML
40-60 yrs
philadelphia gene
overproduction of mature myeloid cells
3 stages: chronic (30%)
risk factor- radiation
splenomegaly
gout (uric acid)
hodgkin’s lymphoma
blood film: reed sternberg cells
ppl 20-40 yrs-younger
leukemia and lymphoma-
most are _ cell orginin
B cell
non hodgkin’s lymphoma
elderly ppl
Usually B cells - CD20+ marker
burkitt’s lymphoma- cMYC oncogene
Follicular lymphoma – BCL-2 translocation
murine splenic cells fused
with myeloma line
no reed sternberg cells
multiple myeloma
abnormal proliferation of plasma cells
Blood film – Rouleaux cells
High ESR > 100 (Erythrocyte sedimentation rate)
Monoclonal IgG band in serum electrophoresis
Urinalysis – Bence Jones proteins
Often tumour formed in various bones i.e. multiple
Specific signs – CRABS ! Ca2+ high (hypercalcaemia) ! Renal failure ! Anaemia ! Bony lytic lesions ! Splenomegaly
Myelodysplastic syndrome
elderly
Ineffective$maturation$of$all$myeloid$cells$(RBC,$WBC,$
platelets)$→pancytopaenia
polycythaemia rubra vera
Pruritis after
hot shower
JAK-2
essential thrombocytosis
overproduciton of platelets
bleeds and clots
myelofibrosis
blood film=tear drop cells, fragments
Massive
splenomegaly
dry tap
