Intervention model description: A prospective parallel group clinical trial
Primary purpose: DIAGNOSTIC

Brief summary: The main purpose of this study is to compare contrast-enhanced ultrasound guided liver biopsy (CEUS-LB) with conventional ultrasound guided liver biopsy (US-LB) in the diagnosis of liver tumors developed on a background of advanced chronic liver diseases. All patients referred to our department with a CT/MRI diagnosis of hepatic neoplasia will be randomly assigned to either CEUS-LB or US-LB. All LB will be performed by the same investigator. For the randomisation the flip coin technique will be used. One investigator without access to previous C/MRI/US report will do the randomization

Detailed description: A prospective parallel group clinical trial will be performed. The study protocol was implemented in our Institute starting January 2011 ending January 1 2020. During this period, all patients with a suspicion of primary liver neoplasia either on CT or MRI will be evaluated in different departments from our Institute for possible inclusion. Patients with a typical aspect of benign FLLs will not be included in the study. Patients fulfilling the following criteria: presence of cirrhosis or other chronic liver disease (according to a liver stiffness evaluated by transient elastography higher than 10 kilopascals), Child-Pugh score no higher than B7 and absence of perihepatic ascites, platelet count \> 50.000 per mm3 or an international normalized ratio \< 1.6; will be further on sent to the department of interventional ultrasound. ). All patients referred to interventional department will underwent a B-mode ultrasound (1 investigator) testing the feasibility of performing liver biopsy. At this time point the conspicuity of the tumors will be recorded into either poorly or not poorly visible. Included patients will be randomly divided by another investigator (T.M.) without access to the previous US, CT or MRI report into two groups: a group that will underwent US guided liver biopsy (USLB) and another one who will underwent CEUS guided liver biopsy (CEUSLB). The randomization will be made based of flip coin technique. The side of the coin (heads-USLB, tails CEUSLB) determined the assignment of each subject. All biopsies will be performed by the same investigator (Z.S.) with an experience of more than 8 years in ultrasound interventions. Patients assigned to USLB or CEUSLB will be blinded. The investigators assessing the outcomes will not be informed about the LB technique used in each patient. The reasons for performing biopsy will be either inconclusive CT/MRI findings , or patients with a typical pattern of HCC on CT/MRI in whom a histological diagnosis is necessary in order to start systemic therapy (sorafenib). Different from other major society's guidelines, in our country a histological diagnosis of HCC is mandatory in patients referred for sorafenib treatment. Patients with small FLLs (BCLC 0 or A) and typical aspect of HCC on CT/MRI will be sent directly to surgery or radiofrequency ablation according to EASL guidelines.

Eligibility criteria: Inclusion Criteria:

* presence of cirrhosis or other chronic liver disease (according to a liver stiffness evaluated by transient elastography higher than 10 kilopascals)
* Child-Pugh score no higher than B7 and absence of perihepatic ascites
* platelet count \> 50.000 per mm3
* international normalized ratio \< 1.6

Exclusion Criteria:

* tumors located tin sonography blind areas
* refuse to sign the informed consent

Primary outcomes:
measure: Number of patients in whom contrast enhanced ultrasound guided liver biopsy leads to the final diagnosis as compared to conventional ultrasound guided liver biopsy. The final diagnosis will be assessed based on histological examination.
timeFrame: From randomisation until the first documented histological diagnosis. In cases with a negative diagnosis based on histology imaging follow-up using CT or MRI will be carried on for a period of at least 12 months.
