Term | Definition |
---|---|
cancer | a term that describes a group of diseases characterized by the uncontrolled growth of dysfunctional cells |
monoclonal | a single cell |
oncogenes | a class of genes that promote cancer formation |
tumor-suppressor genes | a class of genes that turn off or down-regulate the proliferation of cancer cells |
proto-oncogenes | normal genes that code for growth factors or their receptors but can turn into oncogenes |
apoptosis | cell death |
tumor cell proliferation | the growth and reproduction of tumor cells |
tumor burden | the size of a tumor |
chemotherapy | the use of drugs to treat disease; most often refers to drugs used to treat cancer |
cell-kill hypothesis | a hypothesis that presumes each cycle of chemotherapy kills a certain percentage of cancer cells |
cytotoxic drugs | a drug class that works by interfering with some normal process of cell function or proliferation and is used to treat cancer |
cell cycle | the process by which both normal and cancer cells divide |
cell cycle-specific drugs | a drug class that interferes with the division of cells during a susceptible phase of the cell cycle and is used to treat cancer |
cell cycle-nonspecific drugs | a drug class that works at any point in the cell cycle and is used to treat cancer |
combination chemotherapy | combining several different chemotherapy agents simultaneously in order to enhance their effectiveness |
primary chemotherapy | the initial treatment of cancer with chemotherapy and curative intent |
curative | relating to the cure of a disease |
adjuvant chemotherapy | the treatment of residual cancer cells after removal or reduction of the tumor by surgery |
neoadjuvant chemotherapy | the treatment of cancer cells in an attempt to shrink the tumor so that it can be safely and completely removed with surgery |
palliative chemotherapy | a treatment given for cancer that is not curable in order to prolong life and improve quality of life by decreasing tumor size and reducing the symptoms caused by the tumor |
bone marrow suppression | a side effect of chemotherapy which includes decreased production of blood cells and increased risks of infections and bleeding |
alopecia | hair loss |
mucositis | mucosal damage to the lining of the mouth and intestinal tract |
alkylating agents | a drug class used to treat many types of cancer by binding to and damaging DNA during the cell division process, ultimately preventing cell replication |
mutagenic | the ability to cause changes in genetic material |
peripheral neuropathy | very painful damage to the nerves that affect the hands and feet |
ototoxicity | damage to the nerves that affect hearing |
hemorrhagic cystitis | damage and bleeding of the urinary bladder |
antimetabolites | a drug class that works in the synthesis phase of the cell cycle to treat cancer |
hand-foot syndrome | a condition in which patients experience painful sloughing and peeling of skin on the palms of the hands and soles of the feet |
topoisomerases | enzymes important in the process of DNA synthesis and cell replication |
topoisomerase I inhibitors | a drug class used to treat cancer by interfering with the DNA repair function of topoisomerases and disrupting the cell replication process |
anthracyclines | a large category of topoisomerase II inhibitors that inhibit topoisomerase activity by inserting themselves (or intercalating) into strands of DNA (see also intercalating agents) |
topoisomerase II inhibitors | a drug class used to treat cancer by interfering with the DNA repair function of topoisomerases and disrupting the cell replication process |
intercalating agents | a large category of topoisomerase II inhibitors that inhibit topoisomerase activity by inserting themselves (or intercalating) into strands of DNA (see also anthracyclines) |
cardiac toxicity | damage to the heart |
extravasation | severe tissue damage from infusion leaks under the skin during intravenous chemotherapy administration |
vesicants | drugs that cause extravasation injury |
liposomal | drugs that have been prepared in lipid formulations |
microtubule | "important components of cell function play a role in maintaining the shape and structure of cells and are critical elements in the process of cell division or mitosis" |
antimicrotubule agents | a drug class that works by interfering with the formation and function of microtubules, ultimately preventing cell growth and division; used to treat lung, breast, and ovarian cancers, as well as some types of leukemia and lymphoma |
taxanes | a drug class used to treat cancer that blocks cell growth by stopping cell division |
vinca alkaloids | a drug class used to treat cancer that blocks cell growth by stopping cell division |
antiestrogens | a drug class used to treat breast cancer by blocking the activity of estrogen |
antiandrogens | a drug class used to treat prostate cancer by blocking the activity of androgens |
luteinizing hormone releasing hormone (LHRH) | a hormone that stimulates the production of both male and female reproductive hormones |
targeted therapies | a therapy directed at specific molecular entities that are required for tumor cell development, proliferation, and growth |
monoclonal antibody | an antibody that has been developed from a single type of immune cell that was cloned from a parent cell; they are directed at a specific marker or receptor on the surface of tumor cells, leading to destruction of those cells |
signal transduction inhibitors | a drug class that is used to treat cancer by preventing transmission of intracellular signals that stimulate cell proliferation |
angiogenesis inhibitors | a drug class that is used to treat cancer by preventing formation of blood vessels that allow for tumor growth and invasion of surrounding tissue |

Compounding Aseptic Containment Isolator (CACI) | a workstation for handling, preparing, and administering oral or injectable hazardous drugs for product, personal, and environmental protection (see also glove box) |
glove box | a workstation for handling, preparing, and administering oral or injectable hazardous drugs for product, personal, and environmental protection (see also Compounding Aseptic Containment Isolator) |
