Cancer drugs Flashcards
(26 cards)
P53 mutation
occurs in 50% of all human tumors. leads to resistance to therapy.
Imatinib (Gleevec)
Tyrosine hydroxylase inhibitor used for multiple types of cancers such as myelogenous leukemia
nephrotoxic
Hormones
used as treatment for prostate and breast cancers
Retinoic acid
induced differentiantion of some leukemias. (promeylocytic leukemia)
Cyclophosphamide
Hodgkin’s lymphoma, Leukemia, Breast cancer, multiple myeloma.
Alkylates DNA causing miscoding
Can cause: nausea, damage to rapidly growing tissues. CARCINOGENIC
Procarbazine
NITROSOUREA
used for combination regimens for hodgkin lymphoma
CROSS BBB, treat brain tumors
Cisplatin
platinum analog
Nephrotoxic
Methyltrexate
antimetabolite
inhibits tetrahydrofolate- interferes with formation of DNA.
Treats H&N and breast cancers.
Mucositis and diarrhea
Vinblastine
VINCA alkaploids
inhibits tubulin polymerization. ARRESTS CELLS IN DIVISION
can be combined with steroids
treats breast cancer
Doxorubicin
Treats breast cancer.
anthracyclines- antibiotic
form free radicals
treat lymphoma, breast and thyroid cancers
RED URINE
Prostate Cancer
most common for men
Breast cancer
most common for women
lung cancer
most common deadly cancer
Chemotherapy
used after primary treatment, to prevent second tumor dev.
Erlotinib
Blocks ECGR
treats: non-small cell lung and pancreatic cancer
Principles of drug combos
- Usually single drugs at clinically tolerable doses does not cure cancer alone.
- Efficiency usually better in combinations
- Avoid toxicity overlap
- Design optimal scheduling
Drug resistance
melanoma has primary resistance, needs multiple exposures
5-fluorouracil
inhibits thymidine synthase, decreased DNA synthase and DNA synth
Treats Colorectal, anal, breast, H&N and hepatic cancers.
ALL
most common cancer in children
AML
most common acute form of leukemia in adults
Cytarabine is single most active agent
Hodgkin’s lymphoma
Reed sterberg cells
EBV
Treat with anthracycline, doxorubicin, bleomycin, vinblastine
multiple myeloma
bone marrow
treat with alkylating agent + prednisone
Breast cancer
stage 1- treat with surgery alone
stage 2- positive, use chemo post-op
stage3-4- major challenge
prostate cancer
use LH agonists
