module 11 oncology supportive care Flashcards
CINV
Easier to prevent than treat
treatment chose by:
- emetogenic potential of chemo regimen
- risk of delayed N/V
minimal emetogenic risk
no prophylaxis necessary
low emetogenic risk
dexamethasone
or
1st gen 5HT3 antagonist
moderate emetogenic risk
dexamethasone + 5TH3 antagonist
- if pt developes severe emesis after pervious cycle add NK1 antagonist
severe emetogenic risk
NK1 antagonist + 5HT3 antagonist + dexamethasone
Rx for anticipatory NV
benzodiapepines
colony stimulating factors
cytotoxic chemo -> bone marrow suppression -> dec. WBC (particularly neutrophils)
Granulocyte-colony stimulating factors: help to prevent and/or treat neutropenia
anticoagulation
cancer produces hypercoagulabe state in pt
- LMWH is gold standard
hypercalcemia tx
- hydration
- IV bisphosphonates or denosumab
- calcitonin
- dialysis
calcitonin
IV: works quickly to lower Ca levels
- tachyphylaxis after about 8 doses: tolerance
Bisphosphonates and denosumab
effecting at lowering Ca levels
- takes several days to see an effect
tumor lysis syndrome
certain tumors have high tumor burden - chemo kills the cells, spilling contents into blood stream: -- uric acid -- phosphorus -- potassium Accumulation: - arrhythmia - organ failure, renal
tumor lysis syndrome tx
easier to prevent than tx
- hyperhydration
- u/o of 100-200 ml/hr - lower uric acid levels
- allopurinol
- rasburicase
G-CSF med
filgrastim
pegfilgrastim
GM-CSF med
sargramostim
