Cancer Overview
Term | Definition |
---|---|
Benign tumors | Generally well differentiated, do not metastasize, often encapsulated, slow growing, end in –oma (W/L pg. 5) |
Protooncogenes | Normal genes that play a part in controlling normal growth and differentiation (W/L pg. 4) |
Oncogenes | Cancer genes (W/L pg. 4) |
Antioncogenes | Tumor suppressor genes; inactivation of antioncogenes allows malignant process to flourish (W/L pg. 4) |
Sarcomas | Arising from mesenchymal cells including connective tissue, cartilage, bone (W/L pg. 5) |
Carcinomas | Originate from epithelium- tissue that lines body cavities (W/L pg. 5) |
Gompertzian growth curve | Demonstrates that initially tumor growth is exponential but as the tumor enlarges and outgrows the blood and nutrient supply, the rate of cell replication more closely equals the rate of cell death (W/L pg. 5) |
Core needle biopsy | Using a large gauge needle of 14 or 16, tumor architecture is preserved, allowing identification of tumor tissue of origin (W/L pg. 10) |
Alkylating agents | Carboplatin, chlorambucil, cisplatin, cyclophosphamide, dacarbazine, melphalan, nitrogen mustard (W/L pg. 14) |
Antimetabolites | Cytarabine, methotrexate, 5-fluorouracil, 6-mercaptopurine, 6-thioguanine (W/L pg. 14) |
Antitumor Antibiotics | Bleomycin, dactinomycin/Adriamycin, doxorubicin, mithramycin, mitomycin (W/L pg. 14) |
Hormonal Agents | Corticosteroids (dexamethasone, hydrocortisone, prednisone), antiandrogen (flutamide), antiestrogen (tamoxifen, zoladex), gonadotropin releasing hormone (leuprolide) (W/L pg. 14) |
Nitrosoureas | Carmustine, lomustine, streptozocin; lipid soluble- able to cross blood brain barrier (W/L pg. 15) |
Plant Alkaloid | Etoposide, taxol, vinblastine, vincristine (W/L pg. 15) |
Immunotherapy | Amplifies body’s own disease fighting system to destroy cancer through vaccines (W/L pg. 17) |
Interferons | Proteins capable of killing or slowing growth of cancer cells (W/L pg. 17) |
Inerleukin-2 | Growth factor that stimulates an increase in the number of lymphocytes (W/L pg. 17) |
