Neoplasia Flashcards
Formation of abundant collagenous stroma
Desmoplasia
Benign tumor like condition but disorganized and indigenous tissue
Hamartoma
Tumor like condition that is cytologically and architecturally normal
Ectopic origin
Choristoma
Lack of differentiation of cells that is considered the hallmark of malignancy
Anaplasia
Full thickness dysplasia WITHOUT invasion of basement membrane
Dysplasia
True or False:
All metaplastic epithelium is dysplastic
False
Primary route of metastasis for carcinomas
Lymphatic
Primary route of metastasis for sarcomas
Hematogenous
Most common incidence of cancer for children
ALL
Most common incidence of cancer for women
Breast
Most common incidence of cancer for males
Prostate
Most common cause of death of cancer for women and men
Lung
Normal cellular genes whose products promote cell proliferation
Proto-oncogenes
Mutated or overexpressed versions of proto-oncogenes that function autonomously
Oncogenes
Most common type of abnormality involving proto-oncogenes in human tumors
RAS mutation
Another fundamental hallmark of carcinogenesis, these apply breaks to cell proliferation
Tumor suppressor genes
Tumor suppressor gene that is the governor of the cell cycle
Rb gene
Tumor suppressor gene that is called the guardian of the genome
p53
Rb gene binds to E2F and render cells impossible to pass this cell cycle checkpoint
G1-S
Central monitor of stress in the cell, activated by anoxia, inappropriate signaling by mutated oncoproteins or by DNA damage
p53
This syndrome is caused by inactivation of p53 that predisposes a person to many cancers
Li-Fraumeni syndrome
Aerobic glycolysis unique to cancer cells that provide carbon moieties necessary for biosynthesis and growth of cancer cells
Warburg metabolism
Overexpressionof BCL2 apoprotic protein that induces proliferation of germinal center B cells without apoptosis
BCL 2
Stimulates synthesis of VEGF for angiogenesis
RAS
MYC
MAPK
