degrees of differentiation
- what does this mean
- types (3)
- how much it looks like original tissue
- well differentiated (look more like normal cells - behave better)
- poorly differentaiated
- anaplastic= original cell type is unknown
anaplastic
original cell type is unknown
so dont know level of differentiation
well/poorly differentiated
slightly/well differentiated from original tissue
well differentiated= looks like normal cells (behaves more benignly)
poorly differentiated = looks less like normal cells (behaves more malignantly)
neoplasm construction
neoplastic cells- normally monoclonal (genetically identical to parent)
stroma - mechanical supprt + framework- connective tissue. built from growth factors from neoplasm
commonly metastases to bone
BLT
- breast
- lungs
- thyroid
KP nuts
- kidney
- prostate
+renal
metastases arrive in lung
systemic loop to large heart vena cava and large pulmonary arteries so lodges in small lung capillaries
where do gut/colon tumours metastasise to?
liver, via the large portal vein into smaller liver capillaries where it can lodge
so liver acts as ‘tumour filter’
do malignant tumours have
a) growth increase compared to growth of rest of body
b) cell division increase
B!
mitotic activity increases
where do tumours go on to from lung venules
anywhere
