Despite significant progress in non-invasive new radiological imaging techn
iques, a precise diagnosis of focal liver lesions remains difficult and the
refore requires a biopsy of the presumed liver tumour. Liver biopsy results
are most useful when the biopsy is performed for well defined indications
at an early stage during the diagnostic procedure.
In case of lesions highly suspicious for HCC, a biopsy should be performed
in case of other than surgical (curative) treatment. Planning a surgical in
tervention, biopsy of the tumour is not necessary. In case of concomitant l
iver cirrhosis, a biopsy taken from non-neoplastic cirrhotic liver areas ma
y help in assessing the functional capacity. Metastases of the liver with u
nknown primary tumour should be biopsied to get data of the location of the
primary tumour.
Concern has been expressed over the years about seeding of the needle tract
with malignant cells. Indeed, such instances have been recorded with vario
us carcinomas, but they are rare events and seldom of clinical importance.
In conclusion, liver biopsy is an effective and useful procedure in the dia
gnosis of liver lesions and provides significant information for subsequent
patient care.
