Liver Tumours Flashcards
Why are MRIs done
Determines spread of a tumour
Dukes Classification of Colorectal Carcinomas
A = Limited to muscular mucosae (95% 5yr survival) B = Extension through muscularis mucosae (not lymph) (75% survival) C = Involvement of regional lymph nodes (35% survival) D = Distant metastases (6.6%)
What does the T stand for in the TNM system
- Refers to primary tumour and is suffixed by a number that denotes tumour size
- Number varies according to organ harbouring the tumour
What does the N stand for in the TNM system
- Refers to lymph node status and is suffixed by a number that denotes the number of lymph nodes or groups of lymph nodes containing metastases
What does the M stand for in the TNM system
- Anatomical extent of distant metastases
What does a T1 breast carcinoma mean
Equal/less than 20mm in diameter - large numbers denote large tumours
What does an N0 tumour mean
No nodal metastases
What does N1 mean
Some nodal metastases seen
What does N2 mean
Many metastases
What does M0 mean
No metastases present
What does M1 mean
Distant metastases
What is Dukes B classification
pT4 (in peritoneum but untreatable)
P = pathology
How are CRCs surgically treated
- Right sided = Right hemicoectomy
- Transverse = extended right hemicoectomy
- Left-sided = left hemicolectomy
- Sigmoid = sigmoid colectomy
- Low sigmoid, high rectal = anterior resection
Pros of laprosocpic surgery
- Less time in hospital
2. Safe and has same results
Advantage of endoscopic stunting
Less need for colostomy
What is a colostomy
Part of the colon is cut and made exterior (protrudes out of abdomen for management in hospitals
When is radiotherapy used (in which cancers
Colonic cancers = palliation
Rectal cancers = Pre-op
How are polyps treated
Colonoscopy removal
How are rectal cancers treated (they are treated differently to all other cancers of GI)
- Hard to excise
- Identify position on MRI and remove using low anterior resection
- Chemotherapy (neoadjuvant chemo) to shrink tumour if advance
Most common type of tumours found in the liver (malignant or benign)
Malignant
Where is HEPATOCELLULAR CARCINOMA common
China
In what gender does HEPATOCELLULAR CARCINOMA effect
Males
Risk factors for HEPATOCELLULAR CARCINOMA
- Carriers of HBV and HCV have an extremely high risk of developing HCC
- Associated cirrhosis (alcoholic, non-alcoholic fatty liver and haemochromatosis)
How do liver tumours metastasise
Via hepatic or portal veins to lymph nodes, bones and lungs
What do cells do liver tumours consist of
They resemble hepatocytes
Clinical presentations of HEPATOCELLULAR CARCINOMA
- Weight loss
- Anorexia
- Fever
- Fatigue
- Jaundice
- Ache in RIGHT HYPOCHONDRIUM
- Ascites
- Rapid development of all these symptoms
Where is pain in HEPATOCELLULAR CARCINOMA felt
RIGHT HHYPOCHONDRIUM
What can be felt in physical examination for HEPATOCELLULAR CARCINOMA
Enlarged tender liver
Blood tests for HEPATOCELLULAR CARCINOMA
- Serum alpha-fetoprotein raised
What three diagnostics other than blood tests are used for HEPATOCELLULAR CARCINOMA
- Ultrasound
- Enhanced CT
- Liver biopsy
