    • Phase II: objective anti-tumor activity
    • Phase III: compare to standard therapy
  158. how calculate how much chemo to give
    based on body surface area
  159. can nurse admin chemo?
    most institutions require chemo certification for nurse to administer it
  160. routes of chemo administration
    • oral
    • peripheral IV
    • central IV
    • IM
    • intra-arterial
    • via catheter
    • implanted pump
    • directly into body (i.e. bladder)
    • wafers placed in/on cancerous tissues (i.e. brain)
  161. why are there pretreatments for chemo
    b/c each chemo has agent-specific prominent side effects
  162. what to know re: peripherally-given IV chemo
    • careful in vein selection
    • pts often have central access
  163. first thing to do re: extravasation
    • stop the infusion!
    • then proceed w/ antidote administration (they're agent-specific)
  164. are extravasation antidotes agent-specific or one size fits all
    agent-specific
  165. extravasation def.
    • accidental administration of IV meds into surrounding tissue
    • either by leakage (e.g., because of brittle veins in very elderly patients), or direct exposure (e.g. because the needle has punctured the vein and the infusion goes directly into the arm tissue)
  166. pregnancy and RN chemo administration
    no one pregnant or attempting to become pregnant can administer chemo or care for pt w/ chemo precautions
  167. chemo precautions are the same as...
    universal precautions
  168. institutions have specific precautions to follow for chemo pts for how long?
    2-3 days
  169. biologic response modifiers (BRMs) - 2 other names
    • immunologics
    • biologics
  170. how to biologic response modifiers (BRMs) act
    • act by changing the rel btw tumor and host
    • unlike chemo, which directly kills cancer cells
  171. what do biologic response modifiers (BRMs) modulate
    the body's system involved in the growth of the tumor
  172. biologic response modifiers (BRMs) are usually used in combination w/ what
    standard chemotherapy
  173. many biologic response modifiers (BRMs) are used to treat what other chronic diseases
    • rheumatoid arthritis
    • multiple sclerosis
    • Crohn's disease
    • ulcerative arthritis
    • (+ others!)
  174. name 4 biologic response modifiers (BRMs) used to treat cancer
    • Interferons (INFs)
    • Monoclonal Antibodies
    • Colony Stimulating Factors (CSFs)
    • Interleukins
  175. Use interferons for what cancers
    • hairy cell leukemia
    • AIDS Kaposi sarcoma
    • multiple myeloma
    • CML
    • kidney cancer
  176. very common side effect of interferons and sth to know about it
    • flu-like syndrome
    • intensity of side-effect decreases w/ continued exposure
  177. what does interferon (a biologic response modifier) do
    enhances activity of macrophages and NK cells (cells that kill cancer cells)
  178. name a kind of monoclonal antibody
    • cetuximab (Erbitux)
    • ** but LEWIS says this is a tyrosine kinase inhibitor
  179. what do monoclonal antibodies (a biologic response modifier) do
    • they bind to the EGFR (epidermal growth factor receptor), resulting in the inhibition of cell growth, induction of apoptosis (programmed cell death), and decreased vascular endothelial growth factor production
    • inhibits the growth and survival of tumor cells that over-express the EGFR (many human cancer cells do this)
  180. what do monoclonal antibodies inhibit
    growth and survival of tumor cells that over-express EGFR (epidermal growth factor receptor)
  181. what do many human cancer cells over-express
    EGFR (epidermal growth factor receptor)
  182. what do monoclonal antibodies bind to
    • the EGFR (epidermal growth factor receptor)
    • results in inhibition of cell growth
    • results in induction of apoptosis (cell death)
    • results in decreased vascular endothelial growth factor production
  183. monoclonial antibodies are used to treat what cancers
    • colon
    • rectal
  184. name one monoclonal antibodies used
    trastuzumab (Herceptin)
  185. trastuzumab (Herceptin) interferes w/ what
    • HER2/neu receptor
    • it binds to this receptor, causing it (the HER2 protein receptor) to stop reproducing breast cells uncontrollably
  186. HER2 receptor and breast cancer
    in some breast cancers the HER2 receptor is defective and stuck in the "on" position, causing breast cells to reproduce uncontrollably
  187. can cancers develop resistance to trastuzumab (Herceptin)
    yes, and they usually do
  188. what do colony stimulating factors do
    regulate the growth, differentiation, and function of bone marrow stem cells
  189. are colony stimulating factors directly toxic to cancer cells
    no
  190. what's a benefit of colony stimulating factors
    decrease the duration of chemo-induced bone marrow depression
  191. 2 examples of colony stimulating factors
    • filgrastin (G-CSF, Neupogen)
    • epoetin alfa (EPO, Epogen, Procrit)
  192. Interleukin-11 (IL-11, oprelevekin, Neumega) is what and results in what
    • a thrombolytic growth factor
    • results in increased platelet production
