Cancer Behaviour Flashcards
What are the three groups of cancers
Epithelial, mesenchymal and haematological (also neuroectoderm which is a far smaller group)
What do you call epithelial malignancy
Carcinoma
What is the relationship between carcinomas and age
Risk increases associated with long term accumulation of environmental risk (children are rare)
What characterises epithelial malignancy
Local growth. Spreads by haematogenous and lymphatic routes.
Where does testicular carcinoma spread to
Para-aortic lymph nodes due to embryological development
Where do GI carcinomas generally spread to
The liver - other sites are rare
What are mesenchymal tumours
Soft tissue tumours (all kinds and connective tissue) called sarcomas
What do you call smooth muscle tumours
leiomyoma/sarcoma
What do you call skeletal muscle tumours
Rhabdomyoma/sarcoma
What do you call fat tumours
lipoma/liposarcoma
What do you call bone tumours
osteoma/osteosarcoma
What do you call cartilage tumours
Chondroma/ chondrosarcoma
What do you call blood vessel tumours
Haemangioma / angiosarcoma
What do you call nerve tumours
Neuroma/MPNST
What is the age distribution of sarcomas
more common in children
How do sarcomas spread
Local growth is the defining feature (they can get massive) lymphatic spread is very rare. can spread through the haematogenous route and disseminate wildly if left alone enough
