Antineoplastic Drugs Flashcards
against new tissue formation; an agent that counteracts development, growth, spread of malignant cells
ANTINEOPLASTIC
destructive cells
CYTOTOXIC
Rapid production
PROLIFERATING CELLS
Newest drugs are called ———- that target only cancer cells
MONOCLONAL ANTIBODIES
Many antineoplastic possess ————- properties which decrease antibodies and phagocytes and inflammatory reaction
IMMUNOSUPPRESSIVE
old and new drugs are used; combination of drugs used for palliative effects or long term or complete remission in early treatment of CA
chemotherapy
alleviation of symptoms
Palliative
It is an abnormal mass of tissue as a result ofNeoplasia
NEOPLASM
(new growthin Greek) is the abnormal proliferation ofcells
NEOPLASIA
Classification of Neoplasm
- Benign
- Potentially malignant
- Malignant
Warning signs of CANCER
C-hange in bowel or bladder habits
A- sore that does not heal
Unusual bleeding or discharge
T-hickening or lump in the breast or elsewhere
I-ndigestion or difficulty in swallowing
O-bvious change in a wart or mole
N-agging cough or hoarseness
U-nexplained anemia
S-udden unexplained weight loss
they mimic nutrients that the cell needs to grow, tricking the cell into consuming them, so it eventually starves to death
Antimetabolites
tx for wide range of CA like brain tumors, sarcomas, lymphomas and leukemias
Antimetabolites
Examples of medications in use (antimetabolites)
Methotrexate, flurouracil, cytarabine, 6-mercaptopourine
Side effects of antimetabolites
N/V, diarrhea, mucosal ulceration, bone marrow suppression, leukopenia w/ infection, anemia, thrombocytopenia w/ hemorrhage, rash, itching, photosensitivity, scaling, alopecia
Renal and hepatic disorders, pregnancy, GI ulcers
Contraindications of Antimetabolite
act directly onDNA, causing cross-linking of DNA strands,abnormalbasepairing, or DNA strand breaks, thus preventing the cell from dividing. Alkylating agents are generally considered to be cell cycle phase nonspecific, meaning that they kill the cell in various and multiple phases of the cell cycle. Although alkylating agents may be used for most types of cancer, they are generally of greatest value in treating slow-growing cancers
Alkylating agents
tx for wide range of CA like brain tumors, sarcomas, lymphomas and leukemias
Alkylating agents
Carmustine, cisplatin, Cyclophosphamide, thiotepa (used for metastatic ovarian, testicular, bladder CA)
Examples of meds in current use (Alkylating agents)
Side effects of Alkylating agents
N/V, diarrhea, mucosal ulceration, bone marrow suppression, leukopenia w/ infxn, anemia, thrombocytopenia w/ hemorrhage, rash, itching, photosensitivity, scaling, alopecia, neurotoxicity like headache, vertigo and seizures, loss of reproduction capacity, pulmonary fibrosis, hemorrhagic cystitis
Debilitated patients, pregnancy, renal disease
Contraindications of Alkylating agents
These drugs act specifically by blocking the ability of a cancer cell to divide and become two cells. Although they act throughout the cell cycle, some are more effective during the S- and M- phases, making these drugs cell cycle specific. Examples of plant alkaloids used in chemotherapy are actinomycin D, doxorubicin, and mitomycin.
Plant Alkaloids
tx in combination with other CA agent , for leukemias, hodgskin’s disease, lymphomas, sarcomas, etc
Plant alkaloids
Examples of medications in use (plant alkaloids)
Vinblastine or vincristine, paclitaxel (second line to metastatic breast or ovarian)
