treatment
5-FSU
5-fluorouracil
adenocarcinoma
cancerous (malignant) tumor of glandular tissue
adjuvant chemotherapy
assessing primary treatment with drugs, this is given after surgery or radiation to attack small deposits of cancer cells undetected by diagnostic techniques
AFP
alpha-fetoprotein
alkylating agents
synthetic chemical containing alkyl groups that attack DNA
alopecia
chemotherapy for ovarian cancer causes loss of hair on the head
alveol/o
small sac
alveolar
pattern resembling small, microscopic sacs
ana-
backward
anaplasia
loss of differentiation of cells
angiogenesis
process of forming new blood vessels
antibiotics
chemicals produced by bacteria or primitive plants; inhibit growth of cells
antimetabolites
chemicals that prevent cell division; inhibit formation of substances needed to make DNA
antimiotics
drugs that block cell division
apo-
off, away
apoptosis
programmed cell death
ATRA
all-transretinoic
benign tumor
noncancerous growth (neoplasm)
beta-hCG test
test for presence of a portion of human chorionic gonadotropin hormone (marker for testicular cancer)
biological response modifiers
produced by normal cells; directly block tumor growth or stimulate immune system to fight cancer
biological therapy
use of the body’s own defenses to destroy tumor cells
BMT
bone marrow transplantation
bone marrow biopsy
removal of bone marrow tissue for microscopic examination
brachy-
short (distance)
brachytherapy
use of radiation placed directly on or within the cancer
BRC
breakpoint cluster point
bx
biopsy
CA
cancer
CA (cancer)-125
protein marker for ovarian cancer detected in blood
cac/o
bad
cachexia
malnutrition marked by weakness & emaciation; usually associated with later stages of cancer
cancer
characterized by unrestrained & excessive growth of cells
carcin/o
cancer, cancerous
carcinogens
agents that cause cancer
carcinoma
cancerous tumor made up of cells of epithelial origin, 90% of all malignancies
carcinoma in situ
localized growth of cells
cauter/o
burn, heat
cauterization
burning a lesion to destroy tumor cells
CEA
carcinoembryonic antigen
CEA (carcinoembryonic antigen) test
blood test for carcinoembryonic antigen (marker for GI cancer)
cellular oncogenes
pieces of DNA, activated by mutations or dislocation, that can cause a normal cell to become malignant
cGy
centigray (one hundredth of a gray or rod)
chem/o
chemical, drug
Chemo
chemotherapy
chemotherapy
treatment with drugs
combination chemotherapy
use of several chemotherapeutic agents together in treatment of tumors
core needle biopsy
obtaining a plug of tissue for microscopic examination
CR
complete response- disappearance of all tumor
cry/o
cold
cryosurgery
freezing a lesion to kill tumor cells
CSF
colony-stimulating factor
cyst/o
sac of fluid
cystic
tumors from large, open spaces filled with fluid; serous & mucinous tumors are examples
cystitis & proctitis
radiation effects on the urinary bladder & rectum
debulking procedure
may be used to remove as much of primary tumor as possibel
dedifferentiation
loss of differentiation of cells
deoxyribonucleic acid (DNA)
genetic material within the nucleus of a cell; controls cell division & protein synthesis
DES
diethylstilbestrol
differentiating agents
drugs that promote tumor cells to differentiate, stop growing & dies
differrention
specialization of cells
diffuse
spreading evenly throughout the tisse
dysplastic
abnormal formation of cells
EGFR
epidermal growth factor receptor
electron beams
low-energy beams of radiation for treatment of skin or surface tumors
en bloc resection
removal of entire tumor & regional lymph nodes
encapsulated
surrounded by a capsule; benign tumors are usually encapsulated
epi-
upon
epidermoid
resembling epithelial cells
EPO
erythropoietin
ER
estrogen receptor
estrogen receptor assay
test for the presence of a hormone receptor on breast cancer cells
excisional biopsy
removal of tumor & a margin of normal tissue for diagnosis & possible cure for small tumors
exenteration
wide resection involving removal of tumor, its organ of origin & surrounding tissue in the body space
exfoliative cytology
cells are scraped off tissue & microscopically examined
external beam irradiation
applying radiation to a tumor from a source outside the body
fibr/o
fibers
fibrosis
radiation in lungs causes increase in connective tissue
