Cancer and Immunomodulating Agents Flashcards
What are the three primary treatment modalities to address cancer?
surgery
radiation
chemotherapy
What is cytotoxic strategy?
basic strategy of anticancer drugs is to limit cell proliferation by killing the cells and attenuating the growth of cells
Cancer drugs generally either ______________.
inhibit DNA/RNA synthesis
directly inhibit cell division (mitosis)
When are cell-cycle specific drugs effective?
only on cells going through a specific phase
What do cell-nonspecific drugs do?
inhibit replication of ALL cells they encounter
What is growth fraction?
percentage of proliferating cells relative to total neoplastic population
cells in growth fraction are more susceptible to cell-cycle nonspecific drugs
What is the cell kill hypothesis?
each round of chemotherapy will kill a percentage of cancerous cells but not all
What are side effects of cancer treating drugs?
hair loss
anemia
anorexia
What do alkylating agents do?
generate a chemical alkyl group in the DNA chain
What is the largest group of anticancer drugs?
alkylating agents
What pathologies do alkylating agents treat?
leukemia
hodgkin and nonhodgkin lymphomas
brain tumors
melanoma
What are adverse effects of alkylating agents?
blood disorders
GI distress
CNS effects
metabolic disorders
What are antimetabolites?
interfere with normal metabolites
they are especially toxic to cells that have large growth fraction
What are indications for antimetabolites?
breast cancer
GI and liver cancer
leukemias
What are adverse effects of antimetabolites?
blood disorders
GI disorders
CNS toxicity
hepatotoxicity
_____________ are used for neoplastic disease due to high toxicity.
antibiotics
What are indications for antibiotics?
head and neck cancer
genital cancers
leukemia
What are adverse effects of antibiotics?
pulmonary toxicity
skin disorders
blood disorders
GI distress
What are hormones?
drugs that mimic or block the effects of certain hormones
What are indications for hormones?
leukemia
breast cancer
prostate cancer
renal cancer
