Sick Pre-Schooler Flashcards
(78 cards)
hematological malignancy or cancer of the blood which develops in the bone marrow.
leukemia
most common childhood cancer
childhood leukemia
type of leukemia that develops and worsens quickly (over periods of days to weeks).
acute leukemia
type of leukemia that develops over a slower period of time (months), but it is more difficult to treat than acute leukemia, and is more common in adults than in children..
chronic leukemia
6 main types of leukemia that occur in children
• acute lymphoblastic leukemia
• acute myelogenous leukemia
• acute promyelocytic leukemia
• chronic myelogenous leukemia
• chronic lymphocytic leukemia
• juvenile myelomonocytic leukemia
the most common form of childhood leukemia, which makes up 75-80% of childhood leukemia diagnoses.
acute lymphoblastic leukemia
a form of leukemia that affects the lymphocytes, a type of White Blood Cells (WBC) which fights infection. when a patient has ALL, the bone marrow makes too many immature WBC and they do not mature correctly. these WBC also do not work correctly to fight infection. the WBC over-produce, crowding the other blood cells in the bone marrow.
acute lymphoblastic leukemia
accounts for most of the remaining cases of leukemia in children, comprising about 20% of childhood cancer.
acute myelogenous leukemia
a cancer of the blood in which too many myeloblasts (immature WBC) are produced in the bone marrow. the marrow continues to produce abnormal cells that crowd the other blood cells and do not work properly to fight infection.
acute myelogenous leukemia
what gets affected in ALL?
lymphocytes
what gets affected in AML?
myeloblasts
a specific type of AML.
acute promyelocytic leukemia
in this leukemia, promyelocytes are produced and build up in the bone marrow.
acute promyelocytic leukemia
what gets affected in APL?
promyelocytes
in acute promyelocytic leukemia, a specific chromosome translocation where genes on _ changes places with _. this genetic change prevents the promyelocytes from maturing properly.
in acute promyelocytic leukemia, a specific chromosome translocation where genes on chromosome 15 changes places with chromosome 17. this genetic change prevents the promyelocytes from maturing properly.
a chronic leukemia that develops slowly, over months to years.
chronic myelogenous leukemia
rare in children, but does occur.
chronic myelogenous leukemia
a chromosome translocation occurs in pt with chronic myelogenous leukemia where part of the _ breaks off and attaches itself to _, facilitating exchange of genetic material between these. the rearrangement of the chromosomes changes the positions and functions of certain genes, which causes uncontrolled cell growth.
a chromosome translocation occurs in pt with chronic myelogenous leukemia where part of the chromosome 9 breaks off and attaches itself to chromosome 22, facilitating exchange of genetic material between these. the rearrangement of the chromosomes changes the positions and functions of certain genes, which causes uncontrolled cell growth.
another form of chronic leukemia, but is extremely rare in children.
chronic lymphocytic leukemia
a form of leukemia in which myelomonocytic cells are overproduced.
juvenile myelomonocytic leukemia
what is affected in JMML?
myelomonocytic cells
it is sometimes considered a myeloproliferative neoplasm.
juvenile myelomonocytic leukemia
JMML is considered as _.
myeloproliferative neoplasm
JMML is rare and most commonly occurs in children _.
under the age of four
