To minimize the sample variability of liver biopsy, the tissue length should be at least 25 mm. Consequently, more than one biopsy pass is needed with cutting biopsy needles. We aimed to investigate the risk factors of biopsy-related complication, including the number of biopsy passes.All consecutive liver biopsies performed between 2005 and 2014 were included. Biopsies were ultrasound assisted and performed with cutting biopsy needles. A complication was an event where the patient visited a healthcare provider because of biopsy-related complaints. Complications followed by hospitalization 2 or more days or intervention were considered severe.In total, 1806 liver biopsies were analyzed. Overall, 102 (5.6%) complications were observed, of which 31 (1.7%) were severe. One (0.06%) patient died. Common complications were pain (n=75/102; 74%) and bleeding (n=34/102; 33%). Two biopsy passes were not associated with an increased risk of complications compared with one biopsy pass [odds ratio (OR): 1.59; 95% confidence interval (CI): 0.83-3.04; P=0.16], whereas three or more biopsy passes increased this risk compared with one (OR: 2.97; 95% CI: 1.38-6.42; P=0.005) or two biopsy passes (OR: 1.87; 95% CI: 1.10-3.19; P=0.021). The risk of severe complications was not influenced by the number of biopsy passes (P0.24). Hepatic malignancy (OR: 3.21; 95% CI: 1.18-8.73; P=0.022) and international normalized ratio 1.4 or more (OR: 7.03; 95% CI: 2.74-18.08; P0.001) were risk factors of severe complications.Severe complication rate and mortality were low. Performing multiple biopsy passes was not associated with severe complications, whereas hepatic malignancy or elevated international normalized ratio were associated with an increased risk.

In the present study we explored associated risk factors for HCC without cirrhosis and compared patient and tumor characteristics and outcomes in HCC patients with and without underlying cirrhosis. METHODS: Patients with HCC diagnosed in the period 2005-2012 in five Dutch academic centers were evaluated. Patients were categorized according to the presence of cirrhosis on the basis of histology or combined radiological and laboratory features. RESULTS: In total, 19% of the 1221 HCC patients had no underlying cirrhosis. Noncirrhotic HCC patients were more likely to be female and to have nonalcoholic fatty liver disease or no risk factors for underlying liver disease, and less likely to have hepatitis C virus or alcohol-related liver disease than did cirrhotic HCC patients. HCCs in noncirrhotic livers were more often unifocal (67 vs. 48%), but tumor size was significantly larger (8 vs. 4 cm). Despite the larger tumors, more patients underwent resection (50 vs. 10%) and overall survival was significantly better than in cirrhotics. In multivariate analyses, absence of cirrhosis [hazard ratio (HR) 0.49, 95% confidence interval (CI) 0.38-0.63] and presence of hepatitis B (HR 0.68, 95% CI 0.51-0.91) were independent predictors for lower mortality, whereas hepatitis C virus was associated with higher mortality (HR 1.32, 95% CI 1.01-1.65). CONCLUSION: HCC without cirrhosis was strongly associated with female sex and presence of nonalcoholic fatty liver disease or no risk factors for underlying liver disease. In absence of cirrhosis, resections were more often performed, with better survival despite larger tumor size.

Item does not contain fulltext GOALS AND BACKGROUND: Spontaneous rupture is a rare complication of hepatocellular carcinoma (HCC). Treatment options consist of transcatheter arterial embolization (TAE), hepatic resection, and conservative therapy. The best approach is under debate. STUDY: This study presents a review of clinical data of patients with a ruptured HCC admitted to a European tertiary care center. RESULTS: Eleven patients were included; six (55%) had underlying cirrhosis. The majority of patients (73%) had no previous history of HCC. Spontaneous HCC rupture was diagnosed using abdominal computed tomography with or without a diagnostic paracentesis. Computed tomography showed one or two tumors in eight (73%) patients; the other patients had multiple tumors or diffuse infiltrative HCC. Seven (64%) patients were initially treated by TAE and one (9%) patient underwent hepatic resection. The remaining three (27%) patients, all of whom had liver cirrhosis, received conservative therapy. Two patients initially treated by TAE underwent a delayed resection and ultimately received systemic therapy. Overall, at the end of the follow-up period, three patients were still alive at 84, 991, and 1026 days after the initial presentation. Eight (73%) patients had died after a median of 88 days (range 7-417). One year after presentation, none of the conservatively treated patients was alive compared with three out of seven (43%) patients treated with TAE with or without delayed resection. CONCLUSION: Patients with a spontaneously ruptured HCC have a poor prognosis. In selected patients, however, prolonged survival is possible using TAE as initial therapy with or without a delayed resection and systemic therapy.
