14. Primary and secondary liver tumors (symptoms, diagnosis, treatment) Flashcards
Primary types
HCC - Hepatocellular carcinoma
IH-CCC - Intrahepatic choleangiocellular carcinoma
HCC causes
- 90% have cirrhosis (need regular control every 6 months: US, AFP)
- HBV, HCV, Aspergillus flavus
HCC surgical treatment
Liver transplant
HCC Milan criteria
Criteria set for considering liver transplants with CURATIVE intent
Solitary <5cm or max. 3 multiple <3cm
HCC non-surgical treatment
Chemotherapy +/- tumor ablation (RFA) +/-
chemo)embolization (TACE
IH-CCC
- Infiltrative, fast growing, poor prognosis
- LTX: bad result, often recurrent
- Should be resected
Secondary
CLM - Colorectal liver metastasis
NCLM - non-colorectal liver metastasis
NCLM reccomended resections
Neuroendocrine, breast, endometrial cancers
NCLM not reccomended resections
cardia, esophagus, lung, head and neck
Resectability is based on…
- Enough liver volume and function after resection
- Future liver remnant (FLR) with good circulation and biliary drainage
- Total liver function
FLR
- Measure with CT-volumetry or SPECT/CT
- 20 - 25% FLR is enough in normal liver
- 40% for cirrhosis patients
How to increase FLR
Hypertrophy through portail vein occlusion techniques
Prevention of intraop. bleeding
- ischemic preconditioning (less IRI)
- Pringle (intermittent clamping)
How much ischemia can a liver tolerate?
> 40 minutes of ischemia = irreversible damage
