Leukaemia Flashcards
leading cancer for age 15-24
lymphoma
Leading Cancer for 0-14 year olds?
Leukaemia
Most patients cause of leukaemia?
unknown
Leukaemia usually starts with which cells?
pluripotent progenitor cells
Leukaemia mutations generally from?
chromosomal translocation
fusion genes do what?
disrupts normal cells and predisposes to malignant transformation
Acute Leukaemia what kind of cells? clinical course?
immature cells, rapid clinical course
chronic Leukaemia cell type? clinical course?
maturer white cells, gradual course, treatment optional
how would acute Leukaemia kill you
block out capillaries and oxygenation
2 kinds of Leukaemia
lymphoblastic - T and B-cells
myeloblastic - RBCs, platelets, mono, granulocytes
what is thrombocytopenic pupura?
burst capillaries due decreased platelets
Chronic lymphocytic leukaemia cells looks like on slide?
mature, increased numbers, smear cells
flow cytometry used for?
dx markers on lymphocytes to characterize the disease
Chronic lymphocytic leukaemia, you don’t see on slide 2 things:
- granules
2. Auer Rods
Acute lymphocytic leukaemia you see on slide? 3 things
- blastic cells
- granules
- Auer Rods
Hairy Cell leukaemia is acute or chronic?
chronic, good Rx
Chronic myeloblastic leukaemia see what kind of shift?
left shift
acute myeloblastic leukaemia see what in the cell?
+++ Auer Rods
chromosome 15-17 translocation of which 2 regions?
RAR-Alpha and PNL fusion
Philedelphia chromosome which translocation?
9 and 22
what is imatinib? does what?
monoclonal antibody
inhibits the BCR-ABL to induce apoptosis, inhibit proliferation
All Gene fusions cause problems? what are the classes?
- Driver mutations
- passenger mutations
- which are pathogenic?
Acute Myeloid leukaemia genomic and epigenomics contribution?
complex interplay
CLL pro-survival protein is?
BCL-2
what is ABT-199?
selective BCL-2 inhibitor for CLL
when mainly observe patient?
CLL
transplantation for leukaemia first line?
autologous then allograft if necessary
3 sources of autologous transplantation for leukaemia?
- peripheral blood
- bone marrow
- cord blood
Survival of leukaemias? Childhood ALL: Adult AML/ALL: CML: CLL:
Childhood ALL: 80%
Adult AML/ALL: 20-40%
CML: 80-90%
CLL: 5-10 year
