What are the treatments of cancer? | surgery, radiation, chemotherapy |
There are greater chances for cure if the cancer is… | treated early. |
When is surgery performed to remove a tumor? | if it is pressing on nerves, airways, or other vital tissues/it is localized |
When is surgery on tumors not an option? | tumors of blood cells, would not extend client’s lifespan or improve the quality of life |
What is radiation therapy? | high doses of ionizing radiation aimed directly at the tumor |
When is radiation therapy done? | may follow surgery, palliation for inoperable cancers to shrink the size of the tumor |
Why is radiation used for palliation? | relieve pain, difficulty breathing or swallowing |
How is chemotherapy transported? | through blood |
Which chemo drugs are used to treat brain tumors? | those that cross the blood-brain barrier |
What is the goal of chemo? | reach every cancer cell |
Which kinds of cancers do we instill the drugs directly into body cavities? | bladder cancers, CNS cancers (intrathecally) |
Why is chemo given? | attempt to cure, prophylaxis, palliation |
Chemo is often combined with what to increase chance of cure? | surgery/radiation |
Why must every cancer cell be destroyed? | even just one could reproduce |
How many cancer cells does the immune system eliminate? | small amount |
Which cancer cells are difficult to treat with chemotherapy? | physiology of cancer cells are the same as normal cells |
Who prepares the chemo agent? | the pharmacist, usually under a hood |
Who administers chemo? | nurses w/extra education |
What should be done if chemo infusion extravasates? | notify oncologist, leave the IV in place but shut it off, aspirate as much agent as possible, administer antidote, apply heat/cold/steroid cream as ordered, thorough documentation |
Why are different classes of antineoplastics given? | different classes affect different stages of the cancer’s life cycle, allows lower doses of each agent |
Why do we want to give lower doses of antineoplastics? | reduce toxicity, slow development of resistance |
Why do we give single or multiple doses of antineoplastics over several days? | give normal cells a chance to recover, cancer cells may be more sensitive during the time of the next treatment |
Which cells are most susceptible to chemo? | rapidly growing cells |
Why would we push chemo to the maximum possible dosage? | greatest tumor cells killed |
If we push chemo to the maximum possible dosage (toxicity) and do not see adverse effects, what is happening? | not giving enough drug to kill the cancer |
What are the adverse effects to the blood with chemo toxicity? | anemia, thrombocytopenia, leucopenia |
What are the adverse effects to the GI tract with chemo toxicity? | nausea, vomiting, diarrhea, anorexia |
What drugs are given before chemo? | antiemetic meds |
What are some adverse effects of chemo? | fatigue, opportunistic infections, alopecia, stomatitis |
What is stomatitis treated with? | ”Magic” mouthwash |
What is in Magic Mouthwash? | benadryl, Maalox, xylocaine, nystatin |
What do antineoplastic agents act on? | different parts of the cell cycle |
What drugs are antineoplastic agents? | alkylating agents, antimetabolites, antitumor antibiotics, plant alkaloids/natural products, hormones and hormone blockers, miscellaneous |
Which type of antineoplastic drugs are most widely used? | alkylating agents |
How do alkylating agents work? | form bonds or linkages with DNA, changing the shape of DNA which prevents normal DNA function/kill or slow down replication of tumor cells |
When do alkylating agents peak? | 1-2 days after administration |
What interacts with alkylating agents? | echinacea (immune stimulator, interferes with the action) |
What are the adverse effects of alkylating agents? | bone marrow suppression, damage epithelial cells lining the GI tract |
Which drugs are chemically similar to essential building blocks of the cell? | antimetabolites |
How do antimetabolites work? | interfere with nutritional metabolism within the cell |
What drug does cancer cells use to construct proteins or DNA? | antimetabolites |
What do antimetabolites block? | DNA synthesis |
What type of drug is methotrexate (Folex, Rheumatrex)? | antimetabolite |
What type of drug is fluorouracil (5-FU)? | antimetabolite |
What are the actions and uses of methotrexate (Mexate)? | many cancers, psoriasis, rheumatoid arthritis |
What is the usual adverse effect of methotrexate (Mexate)? | pulmonary toxicity |
What is the mechanism of action of methotrexate (Mexate)? | interferes with folic acid use in cells |
How are antitumor antibiotics given? | IV or instilled into cavity |
What drugs are antitumor antibiotics similar to? | alkylating agents |
What type of drug is bleomycin (Blenozane)? | antitumor antibiotic |
What type of drug is doxorubicin (Dozil)? | antitumor antibiotic |
How does doxorubicin (Adriamycin) work? | prevents cell division, delivered per liposomes |
What is a side effect of doxorubicin (Adriamycin)? | change urine to red color |
What is the effect on the heart of doxorubicin (Adriamycin)? | lifetime max dose or it will kill the heart |
What is a common ability of plant alkaloids/natural products? | arrest cell division (also called mitotic inhibitors) |
What kind of drug is vincristine (Oncovin)? | plant alkaloid/natural product |
How is vincristine (Oncovin) given? | IV |
Action of vincristine (Oncovin) | inhibits mitosis |
Adverse effects of vincristine (Oncovin) | nervous system toxicity: numbness, tingling, weakness (sometimes a permanent change) |

What is used to slow breast cancer? | testosterone or antiestrogen (tamoxifen citrate (Nolvadex)) |
What is used to slow the growth of prostate cancer? | estrogen |
What can estrogen for prostate cancer cause? | feminizing effects |
When are corticosteroids usually given? | for palliation |
Adverse effects of hormones used in cancer therapy | higher doses than normally present in body, produce few of the typical cytotoxic side effects, can produce significant side effects when given at high doses for prolonged periods |
