Neoplasia I Flashcards
dysplasia
proliferation cells
loss size shape and orientation
CIS
not invaded BM
nuclear:cytoplasm ratio increased
invasive carcinoma
invaded BM
-metalloproteinase
loss E-cadherin
P-glycoprotein
MDR1
-seen in adrenal cell carcinoma and other cancers
used to pump out toxins
-including chemotherapy agent
mechanism of resistance to chemo drug
reversible
hyperplasia
metaplasia
dysplasia
irreversible
anaplasia
neoplasia
desmoplasia
anaplasia
loss structural differentiation and function of cells
resemble primitive cells
desmoplasia
fibrous tissue formation
-response to neoplasm
grade of tumor
differentiation
stage of tumor
degree of spread
T - tumor
N - nodes
M - mets
important for prognosis
stage
carcinoma
epithelial origin
spread lymphatics
sarcoma
mesenechymal origin
spread hematogenous

immunodeficiency
predispose lymphoma, melanoma, renal cell carcinoma
li fraumeni syndrome
p53 mutation
predispose to lots o cancers
radiation exposure
risk for leukemia, sarcoma, papillary thyroid cancer, breast cancer
oncogenes
need damage only 1 allele
tumor suppressor genes
need damage both alleles
