Pharmacology - Cancer Flashcards
When normal cellular growth control mechanisms are disturbed, the result is the uncontrolled overgrowth of normal tissue and the growth of tumors and/or onset of _________
Cancer
What is another name for cancer?
neoplastic disease
What is a benign tumor?
Stays in one place in the body and is not life threatening (non-cancerous)
What is a malignant tumor?
Can invade nearby tissues and spread to other parts of the body (cancerous)
A _________ _________is not restricted to one area but is scattered throughout the whole body (i.e. Leukemia)
diffuse tumor
Cancer is categorized based on the functions and/or locations of the cells from which the tumor originates:
Carcinoma Sarcoma Leukemia Lymphoma Myeloma Central Nervous System Cancers
_______ is skin or in tissues that line or cover internal organs
carcinoma
______ is bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue
sarcoma
White blood cells and their precursor cells such as the bone marrow cells, causes large numbers of abnormal blood cells to be produced and enter the blood
Leukemia
cells of the immune system that affects lymphatic system
lymphoma
B-cells that produce antibodies – spreads through the lymphatic system
Myeloma
The goal of most chemotherapy regimes is to put the cancer into __________
remission
________drugs not only kill rapidly dividing cells, but also normal cells
antineoplastic drugs
_________ create irreversible cross –links in DNA interfering with the replication process.
Alkylating Agents
What class of drugs may be useful in the treatment of smaller or slow growing tumors?
Alkylating Agents
_________Interfere with the metabolism of cancer cells
Antimetabolites
____________inhibit cell division by interfering with mitosis or DNA replication
antibiotics
_________damage DNA of cells similar to radiation damage.
Nitrogen mustards
________cause DNA damage in replicating cells
Topoisomerase I inhibitors
________inhibit cellular growth and decrease proliferation of cells
Tyrokinase inhibitors
What are some side effects of chemotherapy?
nausea, vomiting, GI upset, hair loss, pain, bone marrow suppression etc
What are the ABC’s of cancer?
Asymmetry, Border irregularity, Color that is not uniform, Diameter greater than 6 mm, Evolving size, shape or color
What are some antimetalobite drugs for cancer
- Methotrexate
- Hydroxyurea
- Pemetrexed
