Seven warning signs of Cancer? |
Change in bowel or bladder. A sore that does not heal. Unusual bleeding or discharge. Thickening or lump in breast/elsewhere. Indigestion or difficulty swallowing. Obvious changes in a wart or mole. Nagging cough or hoarseness. |
|
The basic cell cycle G° |
Resting or dormant stage |
|
Basic Cell cycle G 1 |
The first gap phase |
|
The basic cell cycle S |
DNA synthesis occurs |
|
The basic cell cycle G 2 |
The second gap phase |
|
The basic cell cycle M |
Mitosis occurs |
|
The basic cell cycle and it's importance in the use of antineoplastic agents. |
Some antineoplastic agents target cancer cells in various stages of the cell cycle, which, in part, determines how and when they are used. |
|
Alkylating agents |
Nitrogen mustards, ethyleneimines, alykyl sulfonates, nitrosoureas, and triazenes. |
|
Antimetabolites |
Purine antagonists, adenosine antagonists, pyrimide antagonists, and folic acid antagonists. |
|
Mitotic Inhibitors (plant alkalods) |
Vincristine and vinblastine |
|
Hormonal Therapy |
Estrogens, progestins, and androgens. |
|
Antitumor antibiotics |
Doxorubicin, daunorubicin, idarubicin, plicamycin, bleomycin, and mitomycin. |
|
Biologic response modifiers |
Interferons, interleukin-2, tumor necrosis factor, and monoclonal antibodies. |
|
Alkylating agents |
Cell cycle phase-nonspecific; most active in resting phase; act directly on DNA strand breaks, thus preventing the cell from dividing. |
|
Antimetabolites |
Cell cycle phase-specific; most effective during S-phase; replace natural substances as building blocks DNA molecules, altering the function of enzymes required for cell metabolism and protein synthesis. |
|
Mitotic inhibitors |
Act throughout cell cycle; some are most effective during S- and M-phases; inhibit DNA and RNA synthesis. |
|
Hormonal agents |
Highly selective; either block hormone production or block hormone action |
|
Biologic response modifiers |
Affect biologic responses to a neoplasm in beneficial ways- sometimes acting indirectly to mediate antitumor effects or directly on the tumor cells |
|
Steroids |
Inhibit migration of WBCs and inhibit production of products of the arachidonic acid cascade. |
|
Estrogens |
Promote the release of calcitonin and enhance the availability of vitamin D3 to increase bone formation in postmenopausal patients with breast cancer |
|
Antiestrogens |
Bind to estrogen receptors, preventing estrogen from binding to these receptors |
|
Antiandrogens |
Block the synthesis of endogenous testosterone |
|
Biologic response modifiers are created and how they work |
Human proteins modified by recombinant DNA technology to produce agents with potent effects on the function and growth of normal and neoplastic cells. |
|
Biologic response modifier examples |
Interferon, interleukin-2, tumor necrosis factor, and monoclonal antibodies |
|
Monoclonal antibodies |
Can be used to specifically track down and purify the specific protein that induced their formation |
|
Emulating agents |
Oral mucosal ulceration and intestinal denudations, pulmonary fibrosis and venoocclusive disease in the liver, renal failure, or central neurotoxicity with seizures, coma, and at times, death; most of these agents cause hair loss; some cause nausea and vomiting; ifosfamide is the most neurotoxin of this class, producing altered mental status, coma, generalized seizures, and paralysis. All these agents have toxic effects on the reproductive system. |
|
Antimetabolites |
Nausea, vomiting, hepatotoxicity, bone marrow depression, headache, hearing loss, sleep disorders, depression, myelosuppression, :* disturbances, hair loss, dermatitis, nail changes, skin rashes, hyperpigmentation, photosensitivity, hyperuricemia, and inflammation of the tongue. Methotrexate may cause serious adverse effects, including severe leukopenia, bone marrow aplasia, and thrombocytopenia. |
|
Mitotic Inhibitors ( plant alkaloids) |
Nausea, vomiting, diarrhea, hair loss, dizziness, weakness, headache, depression, stomatitis, anemia, and hyperpigmentation of the nails, tongue, and oral mucosa. |
|
Hormonal therapy |
GI disturbances, possible impaired fertility, menstrual irregularities |
|
Antitumor antibiotics |
Bone marrow suppression, stomatitis, GI upset, hair loss, hyperpigmentation, skin ulceration, pulmonary fibrosis, serious renal impairment. |
|
Biologic response modifiers |
Nausea, vomiting, weight gain, fluid retention, and damage to the liver, lungs, nerves, or kidneys. |
