types of cancer Flashcards
epithlial tumour is defined as
resting on basement membrane
carcinoma
epithelial malignancy
3 malignancies associated with children
blood
brain
bone
epithelial vvv rare
how does carcinomas spread
via blood and lymph nodes
spread of testicular cancer
will follow lymphatic spread and so vasculature
testicular artery is a direct branch of the aorta, will spread to para-aortic lymph nodes
likely metastases for lung cancer
bone, brain, adrenal, liver
most GI malignancies spread to
liver
name for mesenchymal tumours
sarcomas
colorectal cancer spread
lymph spread, follows nodes in mesentery and the vascular supply
malignant smooth muscle tumour
leiosmyosarcoma
benign cartilage tumour
chondroma
t/f mesenchymal tumours spread via lymphs
false haemtogenous spread (mainly T, little N)
how are mesenchymal tumours diagnosed
FISH
genetics mesenchymal tumours are often associated with specific large
translocations
sarcomas are described as spindle cell lesions, explain this appearance
very long elongated shape (cigars)
leukemia
malignant cells in blood and bone marrow
leukemia cannot metastasise t/f
true, there is no primary organ
symptoms of bone marrow involvement in leukemia
make less blood cells, platelets, granulocytes and normal b cells
may involve liver and spleen - organomegaly
gliomas ar
brain tumours (glial cells)
leukemia has signs and symptoms similar to
TB
lymphomas
solid white lumps resembling cell of origin
large lymph nodes across areas that dont fit with anatomical drainage of an epithelial malignancy indicates
lymphoma
lymphomas are likely to be pleomorphic
no
monotonous and clonal
