Abstract
BackgroundThe aim of this study was to compare the diagnostic accuracy of the FibroTouch and FibroScan in patients with chronic liver disease (CLD) for staging fibrosis. MethodsA prospective study was conducted in 435 CLD patients between 2014 and 2017. Index tests (FibroTouch, FibroScan, APRI, and FIB-4 score) and a reference standard (liver biopsy) were performed within one week. ResultsThe area under the receiver operating curve (AUROC) of the FibroTouch was similar with that of the FibroScan for the diagnosis of significant fibrosis, severe fibrosis, or cirrhosis; however, the AUROC of the FibroTouch was higher than that of APRI or FIB‐4 (p < 0.001). There was a significant correlation (rho = 0.85, p < 0.001) between the FibroTouch and FibroScan for liver stiffness. The overall diagnostic accuracy of FibroTouch for significant fibrosis, severe fibrosis, or cirrhosis was 73.3%, 83.2%, or 84.1%, respectively. No significant differences between the FibroTouch and FibroScan were detected regarding the sensitivity, specificity, negative predictive value, positive predictive value, and accuracy. The optimal cut-off values for each stage of fibrosis were similar between the FibroTouch and FibroScan. ConclusionThe FibroTouch is a valuable diagnostic tool for diagnosing liver fibrosis with good diagnostic accuracy which was comparable with that of the FibroScan, but superior to that of the APRI and FIB-4.
