Q

Hep B reactivation

A

CD-20 mAb (rituximab)
-per asco there is risk with all antineoplastics
- get hb surface antigen, anti-hb Core total, anti-hb surface total
-may need tenofovir or entecavir ppx

*consider antiviral ppx for HBsAg+ or HBcAb+

Q

Hypersensitivity rxns

A

-platinums- occurs later in cycle (cycle 5+) d/t immune rxns
-taxanes- occurs early in cycle d/t solvent (paclitaxel has cremophor (Cremephor now called Kolliphor) and docetaxel has polysorbate 80)
-many mAbs
-fosaprepitant: polysorbate 80

Q

Extravasation

A

-Doxorubicin and “rubicins” - cold compress, dexrazozane, DMSO
-dactinomycin- cold compress, DMSO
-meclorethamine- Cold compress, sodium thiosulfate, DMSO
-mitomycin- cold compress, DMSO
-trabectedin- cold compress
-vinca alkaloids: DRY warm compress, hyaluronidase
-Brentuximab vedotin
-ado-trastuzumab- cold compress
-taxanes (not nab-paclitaxel)-hyaluronidase

Others:
-carmustine
-mitoxantrone
-streptozocin
-teniposide (warm compress)
-cisplatin if > 20 mL of 0.5 mg/mL, (sodium thiosulfate)
-lurbinectedin
-trabectedin

Irritants:
Bendamustine-tx like Mechlorethamine
Oxaliplatin- warm compress
Etoposide- warm
Many others

-heat for non DNA binding but cold for DNA binding bc DNA binding isn’t neutralized/metabolized as it spreads, so it’ll just keep damaging tissue- so keep it in the same place
-DMSO 99% is topical- don’t use with dexrazoxane !!

DNA binding: anthracyclines, dactinomycin, mitomycin, mechlorethamine

Non-DNA binding: taxanes, vincas, Amsacrine, vindesine , trabectedin

-stop infusion, leave venous access device in place, elevate limb, aspirate drug, do NOT flush line, remove needle, compress

-if using dexrazoxane must start within 6 hours
-give antidote through a DIFFERENT venous access site (unless hyaluronidase)
-do NOT use DMSO with dexrazoxane

BCR-ABl TKI comparison

A

imatinib
-fluid retention, nausea, rash, muscle cramps (tonic water or fluid w/ quinine, or calcium)
-with food

dasatinib
-fluid retention (pleural/pericardial effusions) (does NOT decrease over time like most ADRs), PAH, plt inhibition/bleed , avoid if pulmonary issues
-with or without food

nilotinib
-qtc prolongation, pancreatitis, peripheral arterial occlusive dx, metabolic syndrome
-BID so don’t use if poor adherence
-without food

bosutinib
-diarrhea, hepatotoxicity, avoid if GI issues
-with food

ponatinib
-ischemic rxns, arterial occlusion, HTN, pancreatitis, bleed risk,hepatotoxicity, heart failure, avoid if CV issues
-with or without food

asciminib
-well tolerated, asymptomatic amlylase or lipase elevation
-without food
-only one that doesn’t prolong QTc

Note: Ponatinib and dasatinib cross BBB the best

Hepatotoxicity: bosutinib, Ponatinib, nilotinib

Pancreatitis: Ponatinib, nilotinib

-all are 3A4 substrates
-imatinib and nilotinib are 3A4 and 2D6 inhibitors
-3 second gens avoid with acid suppressive therapy
