Card preview (24)
how many types of cancer treatments are there?
5 (chemotherapy, surgery, radiation, targeted therapy, immunotherapy)
focus has shifted from curing cancer to making it a – disease
chronic
are targeted therapy and immunotherapy always effective
no, highly variable
what type of therapy? targets dividing cells and induces cell death
cytotoxic chemotherapy
what type of therapy? diminishes hormone levels or hormone signaling activity in hormone sensitive cancers
hormone therapy
what type of therapy? antibody targets a specific protein and results in cell death, blockade of receptor-ligand interactions, or otherwise interferes with necessary processes for the tumor
monoclonal antibodies
what type of therapy? vaccine stimulates immune system to detect and remove cancer cells or prevents the induction of cancer by certain infectious agents
vaccine therapy
what type of therapy? immunomodulatory activity, possible antiproliferative activity
cytokine therapyw
what type of therapy? small molecules that inhibit a specific molecular target that is considered fundamental to the cancer cell survival
targeted therapy
what does nitrogen mustard do to DNA?
DNA alkylating agent
what is the first successful chemo drug
methotrexate
deficiency in which vitamin/molecule causes anemia?
folic acid/vitamin B9
— inhibit biosynthesis of purines and some amino acids
folate antagonists
what type of chemotherapy agent? damage DNA by covalent binding of alkyl groups, preventing cell division and leading to cell death
alkylating agents
what type of chemotherapy agent? interfere with DNA replication through a poorly defined mechanism, thought to occur via intercalation into DNA and displacement of DNA binding proteins, or by causing DNA breaks
anthracyclines
what type of chemotherapy agent? inhibit DNA replication by causing single and double strand DNA breaks or corsslinked DNA strands
anti tumor antibiotics
what type of chemotherapy agent? interfere with production of purine nucleotides for synthesis of DNA, preventing cell division (a type of antimetabolite)
antifolates
what type of chemotherapy? substitute components normally used for inclusion in RNA or DNA, interfering with gene transcription or chromosomal replication and causing damage during S phase, chemical structures are often similar to nucleosides
antimetabolites
what type of chemotherapy agent? form covalent intra-strand DNA cross-links, preventing cell divison and leading to cell death
platinum analogs
what type of chemotherapy agent? stabilize microtubules, preventing completion of mitosis, leading to cell death
taxanes
what type of chemotherapy agent? interfere with topoisomerases, which separate strands of DNA for copying during S phase
topoisomerase inhibitors
what type of chemotherapy agent? unlike taxanes, these drugs interfere with microtubule assembly during M phase, preventing cells from dividing
vinca alkaloids
are chemotherapy agents synthetic or natural products?
can be either
many chemotherapy agents were developed pre—
1980
