Malignancies Flashcards
Acute Luekemias
Reason: White blood cell cancer
Symptoms: Cytopenia ( Anemia, bleeding, Infection), Leukostasis (blast blocking blood flow: cause respiratory and heart problems), DIC and tumor lysis
Finidngs: 20% blast in blood, low WBC bc it lowers everything
labs: blood can have tumor lysis, Coag can show DIC
Signs of Tumor Lysis
increase: potassium, uric acid, phosphorus, LDH
Decrease: Calcium
Signs of DIC
Increase: PT, aPTT, Thrombin time, D dimers
Decrease: fibirogen
Acute myloid leukemia
AML
Origin: Myloids
more common in older age
Acute Lymphoid leukemia
ALL
Origin: Lymphoids
Common in kids
t(9:22) Ph+ philadelphia chromosome B cell
gets into the CNS so need drugs that get into to treat
ALL and AML treatments
leukemia
maybe curable, based on age, Cytogenetics, high risk of HSC transplant
Acute leukemia Intial management
- infection
- bleeding
- Leukostasis AML»ALL
- tumor lysis ALL»AML
- DIC high risk with APL(AML subtype)
How to treat tumor Lysis
ALL>AML>agressive lymphomas
Prevention: allopurinol (bc of the purine) in all leukmias and aggres lymphomas and hydration
Treatment: Hydration and rasburicase (urate oxidase)
AML treatment base on performace
Good 50-60, Bad < 10
begin inudction:
good 7 + 3 regiment (Targeted therapy C A)
Bad Hypomethylating agents, Venetoclax
Acute Promyelocytic Leukemia
HIGHEST RISK OF DIC
Granules can change into Rods ( tell tail sign that its APL)
Character: T(15;17) PML-RARalpha
TREATMENT: ATRA and Arsenic trioxide no chemotherapy
best early detection
