Cancer Chemotherapy-Targeted Therapy Flashcards
Targeted therapy pros and cons
Pro: ⬇️ AE vs cytotoxic agents
Con: resistance is common, don’t work for everone, testing is required
Anti androgen therapies Anti estrogen therapies Kinase inhibitors Targeted delivery of toxins Anti angiogenesis agent Immunostimulants
Targeted therapy options
Anti androgen therapy
Block androgens-GF
Rx for prostate cancer
Limited duration
AE: hot flashes, impotence, ⬇️ libido, ⬇️ muscle and bone mass
Targeted therapy
MOA: target a specific growth factor to target only the affected tissue/GF
- block GF or surface receptor
- inhibit cellular enzyme
- mark cells for immune attack
- deliver toxic compounds
- inhibit angiogenesis
Anti androgen therapy
Available products
1) gonadotropin releasing hormone agonists
2) GnRH antagonists
3) androgen receptor blockers
4) CYP17 inhibitors
Leuprolide
Tiptorelin
Goserelin
GnRH agonists
Aborelix
Degorelix
GnRH antagonists
Flutamide
Bicalutamide
Nilitamide
Androgen receptor blockers
Anti estrogen therapy options
Block estrogen (GF)
Rx for breast cancer
1) selective estrogen receptor modulators (SERMs)
2) pure estrogen ER antagonist
3) aromatase inhibitors
Selective estrogen receptor modulators (SERMs)
Inhibit/inactive ER in specific tissues
AE: hot flashes, thromboembolism, endometrial cancer risk
Tamoxifen
Taremifene
Raloxifene
SERMs
Pure estrogen ER antagonist
-fulvestrant
No risk of endometrial cancer
Aromatase inhibitors
Pain- musculoskeletal/joint pain
Osteoporosis
Anastrozole
Letruzole
Exemestone
Aromatase inhibitors
Kinase inhibitors
-“nib”
The most rapidly growing class of anti cancer drugs
-kinase: enzyme that activates/regulates proteins by -P them
AE: N/V/D, non allergic rash, myelosupression, HTN, QT prolongation, skin/hair changes, lung disease
