High Emetic Risk Drugs
Streptozosin Mechlorethamine Darcarbazine Cyclophosphamide >1.5gm/m2 Carboplatin AUC >6 Cisplatin Doxorubicin + Cyclophosphamide
High Risk Antiemesis Combo regimen
5HT3 + NK + Steroid (and/or Benzo)
Antiemesis Rescue Tx
Something not already in use; D2A common for breakthrough
Febrile Neutropenia Empiric Coverage
Antipseudomonal Beta-Lactam (cephalosporin)
When to use gCSF
When patient is becoming neutropenic (>20% risk)
What to do as secondary prophylaxis if pt has history of Febrile Neutropenia and/or previous gCSF use
Add gCSF, if previously used then Reduce chemo or change Tx
What labs/levels are high risk for TLS?
Uric Acid (>8) Potassium >6; Phosphorous >6.5 and Calcium <7 or >14
Tx for Uric Acid abnormalities in TLS
Allopurinol (also can be used prophylaxis)
Rasburicase
Tx for Hyperkalemia in TLS
Regular Insulin in D50W (if BG <250) Nebulized Albuterol + Sodium Bicarbonate Furosemide SPS (sodium exchange) Patiromer (Ca exchange)
Tx for Hyperphosphatemia if no Hypercalcemia
Calcium Carbonate
Calcium Acetate
Aluminum Hydroxide
Tx for Hyperphosphatemia if Hypercalcemia
Renagel Renvela Lanthanum Carbonate Ferric CItrate Sucroferric Oxyhydride
Tx for Hypercalcemia
Hydrate First
Bisphosphanates
Calcitonin
* if refractory w/ Bisphosphanates may add denosumab
Strongest Mutation correlated with Breast Cancer
BRCA (1 and 2)
- also at higher risk for ovarian/prostate
Breast Cancer Tx if ER/PR (+) and HER-2 (+/-)
Hormone Tx
- Tamoxifen or LHRH (premenopausal)
- Aromatase inhibitor (postmenopausal)
Breast Cancer Tx if ER/PR (-) and HER2 (+)
Trastuzumab +/- (Carboplatin + Docetaxel)
Breast Cancer Tx if ER/PR (-) and HER2 (-)
Cyclophosphamide + Doxorubin + Taxane
Breast Cancer Emetogenic Regimen
Fosaprepitant + Dexmethasone + Ondansetron
PRN prochloperazine and Ativan
+ Olanzapine if refractory
Breat Cancer Trastuzumab adjunctive
Pentuzumab ( only w/ Trastuzumab)
Neratinib
Used in HER2 (+)
TKI; prevents formation of HER2 epitopes
Diarrhea major side effect
Lapatinib
Used in HER2 (+)
TKI; inhibits EGFR & HER2;
Pablociclib
Used in HER2(-) ER/PR (+)
Cyclin Depende Kinase inhibitor
Inhibits CDK4/6 by blocking retinoblastoma hyperphosphorylation
Androgen Deprivation Therapy Options
- Oriechiectomy (Castration)
2. Medical Androgen Deprivation (Chem Cast)
LHRH Agonist Place in therapy
Suppresses LH an FSH/Testosterone Production
Leuprolide
Goreselin
Triptorelin
- See initial disease flare up to 2 weeks; Use anti-androgens prior to Tx for 1-2wks
LHRH Antagonists
Use if high tumor burden
Binds to GNRH receptor in pituitary, directly suppresses androgen production
Degarelix agent of choice
