Other pearls
-granisetron ER injection given 30 mins before on day 1 and lasts 7 days
-aprepitant: inhibitor of 3A4 but inducer of 3A4 and 2c9 if given for >14 days
-aprepitant increases: oral contraceptives, warfarin, dex/MP

-rolapitant: single dose (very long half life) minimum 2 week intervals, no effect on 3A4, caution with gefitinib, MTX, lapatinib, mitoxantrone, imatinib, topotecan, irinotecan, cycslosporin, statins, PO only

Steroids
-unknown exact MOA
-avoid 3-5 days before and 90 days after CAR-T
-no data saying we can’t give dex before regimen that contains an ICI
-olz is a good alternative to dex

Reglan and trimethobenzamide
-reglan: blocks D2, blocks peripheral 5HT3 (high dose), increases motility

phenothiazine
-promethazine, compazine, chlorpromazine
-more hypotension than butyphenones

butyrophenones
-haldol, droperidol
-suitable alternative is phenothiazine fails

Dex:
-can cause hiccups
-can cause dyspepsia
-avoid 3-5d prior to and 90 d after CAR-T

HEC: 5Ht3, dex, NK-1, OLZ (dex and olz should be continued on DAYS 2-4to prevent delayed CINV). Note olz dose 5 mg OR 10

MEC: 5HT3 + dex (continue one or the other for days 2-3), could also chose a 3 drug regimen

LEC: single drug 5HT3 or dex, or reglan or compazine

Minimal: none

oral
Moderate-high: 5HT3 daily + breakthrough

Minimal-low: breakthrough only

Multi-day
-Tricky- evaluate emetogenic potential for each day

Q

When to consider EP over BEP in testicular cancer

A

> 50 y/o, reduced GFR, or pulmonary comorbidities

97
Q

Rasburicase pearls

A

After administration blood samples must be chilled and collected in tube containing heparin and assayed within 4 hours or UA will be falsely low

Avoid in G6PD deficiency

0.2 mg/kg/day x 5 days or 1-2 fixed doses of 3-7.5 mg

98
Q

TLS prevention

A

Low risk: oral hydration and monitor

intermediate-high risk:
-BL G6PD
-IV Normal Saline +/- loop diuretics
-allopurinol 300-400 mg/m2/d (don’t renally dose for this indication)
-maybe rasburicase for high risk

Fun facts:
-phosphate binders only decrease dietary phos, not what’s released with TLS- fluids and HD is really all we can do- use if phos increase >25%
-don’t tx asymptomatic hypocalcemia (risk of precipitation with phos). Give ca gluconate if needed
-loop diuretics can be important for fluid overloaded patients- great trick to have up your sleeve

Dialysis is always last resort for treatment

99
Q

CNS ppx parenchyma vs leptomeningeal dx

A

Parenchymal: HD-MTX (not intrathecal)

Leptomeningeal: HD-MTX, IT MTX, IT Cytarabine (could give IT MTX + Cyt + dex)

in other words- IT does not cover parenchyma dx- so IT only can be risk in some diseases like Burkitts
