This study found that preoperative liver stiffness measurement using magnetic resonance elastography can predict intrahepatic recurrence after curative resection for hepatocellular carcinoma, and it was identified as an independent predictor along with vascular invasion.
Background: Liver stiffness measurement using magnetic resonance elastography can assess the severity of liver fibrosis, which is significantly associated with recurrence after curative resection for hepatocellular carcinoma. The aim of this prospective study was to investigate whether preoperative liver stiffness measurement by magnetic resonance elastograhy can predict recurrence after curative resection for hepatocellular carcinoma. Methods: Patients who underwent preoperative liver stiffness measurement and curative resection for hepatocellular carcinoma were enrolled in this study. Potential associations between liver stiffness measurement, along with other clinical and pathologic variables, and intrahepatic hepatocellular carcinoma recurrence were analyzed. Results: In total, 156 patients were included in this study. During a median follow-up period of 25.1 months (range, 6.0-60.5 months), 72 (46.1%) patients with hepatocellular carcinoma had an intrahepatic recurrence. The median disease-free period after resection was 17.9 months (range, 1.0-60.5 months). In the multivariate analysis, liver stiffness measurement (hazard ratio, 1.27; 95% confidence interval, 1.11-1.43; P < .001) and vascular invasion (hazard ratio, 1.96; 95% confidence interval, 1.15-3.25; P = .013) were identified as independent predictors of recurrence. When the optimal cutoff point was set at 4.53 kPa using the minimal P value approach, the disease-free period after curative resection in 71 patients with a liver stiffness measurement value >4.53 kPa (11.3 months [range, 2.0-60.5 months]) was significantly shorter than that of 85 patients with a liver stiffness measurement value <4.53 kPa (22.5 months [range, 1.1-60.5 months]; P < .001). Conclusion: Liver stiffness measurement using magnetic resonance elastography is a useful preoperative predictor of intrahepatic recurrence after curative resection for hepatocellular carcinoma.
