The factors associated with the decision to perform a biopsy and the clinical impact have not been previously studied. We collected data of patients diagnosed with HCC between 2004 and 2015 from the National Cancer Database. We assessed associations between biopsy and survival with demographic and clinical factors. We included 160,507 patients. The median age was 62 (40-90), 74.1% were male and 74.9% were white. Over the 12-year period, 47.7% (76,524/160,517) underwent a biopsy. Factors associated with a biopsy were black race, older age, presence of metastatic disease, larger tumor size, and treatment at a community cancer center. Factors associated with increased mortality were older age, higher comorbidity index, larger tumor size, presence of metastatic disease, higher AFP and elevated bilirubin. There was a significant decreased use of biopsy over successive years (2007-2015). After adjusting for prognostic factors, biopsy had no significant impact on survival HR 1.01 (95%CI 1.00-1.03. p=0.07). A significant number of patients underwent a biopsy. Performing a biopsy did not have a significant impact on survival. A significant number of patients underwent a biopsy. Performing a biopsy did not have a significant impact on survival. The objective of the current study was to summarize and evaluate all published evidence regarding viscoelastic testing in the field of liver surgery. A systematic search of the literature was performed using Medline/PubMed, Scopus, Cochrane Library Central, Google Scholar, and clinicaltrials.gov databases.
