Nadir
WBC Lowest point occurs after 7 - 14 days after chemo. recovers about 3 - 4 weeks post txt.
Neutropenia
ANC <1,000
Severe Neutropenia
ANC < 500
Profound Neutropenia
ANC <100
Calculate ANC
WBC x ( Segs% + bands% )
Fligrastim
Brand, MOA, SE
Neupogen, Zarxio, Granix (tbo-filgrastim)
MOA: Granulocyte - Colony stimulating agent
SE: Bone paine, fever
Dose no sooner than 24 hours up to 3 days
Pegfilgrastim
Neulasta
MOA: G-CSF
SE: Bone pain, Fever
do not give within 14 days of next cycle. since 1 dose of this is equivalent to 14 doses of filgrastim
Sargramostim
Leukine
MOA: GM-CSF
SE: Fever, Bone pain, Myalgias, Arthralgias, rash
Fibrile neutropenia
FEVER:
Single oral temp > 38.3 C (101F)
or
ORal temp > 38C (100.4F) for over an hour
Neutropenia:
ANC <500
or
ANC is expected to be less than 500 in 48 hours
ABX in febrile neutropenia
Cover for gram - (P. Ag)
Low risk Oral anti-psuedomonas agents:
Ciprofloxacin + Augementin
Cipro +/- Clindamycin
Levo
High risk (IV anti-psuedomonas agents): Cefepime, Ceftazidime, Mero/imipenem, pip-tazo
Anemia in cancer
ESA Increase mortality in cancer patients so use only if the intent is NOT curative.
If using ESA add 2 months of chemo to the current regiment
initiat when Hgb is less than 10 (use lowest dose possible)
Thrombocytopenia
Give Transfx if PLT is below 10,000 or 20,000 with bleeding.
AVOID NSAIDS since it reduces function of PLT due to inhibiting TXA
Chemo induced N&V
Acute - within 24 h (Serotonin is responsible so use 5HT3 - RA)
Delayed - 1 to 7 days after chemo ( supstance P is responsible so use NK-1 RA , palonosetron or dexmethasone)
Anticipatory - before chemo (BZD)
High Emetic Risk drugs therapy
3 drug regiment:
NK-1 RA + 5HT3-RA + Dex
Dex + Akynzeo (Netupitant/Palonestron)
