  1. What happens when cancer is untreated?
    • Reduced immunity and blood-producing function
    • GI problems
    • Motor snd sensory deficits
    • Decreased respiratory function
  2. Define Cachexia?
    extreme body wasting and malnutrition
  3. Prophylactic surgery
    The removal of 'at risk' tissue to prevent cancer development
  4. Diagnostic surgery
    • Biopsy
    • The removal of all parts of a suspected lesion for exam and testing
  5. Curative surgery
    Focused on removal of all cancer tissue
  6. Cancer control
    Cytoreductive
    Removing part of the tumor and leaving a known amount of gross tumor
  7. Palliative surgery
    Improves quality of life during the survival time and is not focused on the cure
  8. Second-look surgery
    Rediagnosis after treatment
  9. Reconstructive surgery
    Increase function or enhances appearance or both
  10. X - Rays
    radiation hat is generated by a machine

    The amount of radiation delivered to a tissue
  12. Radiation dose
    The amount of radiation absorbed by the tissue
  13. R.A.D.
    Radiation Absorbed Dose
  14. Teletherapy
    • Distant therapy
    • Source is external
    • Pt is not radioactive
  15. Brachytherapy
    • Short or close therapy
    • Source is within the pt
    • Pt is radioactive
  16. Chemotherapy
    The treatment of cancer with chemical agents
  17. What is it called when chemo is used with surgery or radiation?
    Adjuvant
  18. Types of chemotherapy drug classes?
    • Antimetabolites
    • Antitumor antibiotics
    • Antimitotics
    • Akylating agents
    • Toposomerase inhibitors
  19. Define nadir
    The time when bone marrow activity and WBC counts are at the lowest level
  20. Extravasation
    The movement of the IV needle so the drug leaks into the surrounding tissues
  21. Vesicants
    chemicals that damage tissue on direct contact
  22. Cytoprotectants
    agents with drugd that protect specific healthy cells
  23. How is chemotherapy administered?
    • On regular basis
    • Timed to maximize cance cell kills
    • according to pt reesponse to therapy
    • Every 3-4 weeks for a specified # of times
  24. Biological Response Modifier drugs
    Stimulate the immune system to produce cells
  25. Interleukins
    Help immune system recognize and destroy cancer cell
  26. Interferons
    help cancer cells revert to original characteristics
  27. Monoclonal antibioties
    Bind with the cell and prevent cell division
  28. Sepsis
    condition in which organisms enter the bloodstream

    • TX
    • Prevention
    • Iv antibiotics
    • Anticoagulants

    (Human leukocyte antigen HLA)
    (Cytokines IL-2)
    • ExperimentalMakes tumors mor susceptable to damage or death by other treatments
    • Injects tumor cells with HLA or IL-2 enabling the immune system recognize cancer cells as foreign and kill them
