ARTICLE HIGHLIGHTS
Research background

Surgery is the main treatment for hepatocellular carcinoma (HCC). However, 30%-50% of patients develop recurrence within 2 years, which is the main cause of death.

Research motivation

Screening patients with high recurrence risk plays an important role in making reasonable clinical decisions.

Research objectives

To combine contrast-enhanced ultrasound (CEUS) liver imaging reporting and data system (LIRADS) with serology biomarkers to construct a non-invasive model predicting the early recurrence of HCC, and verify the model.

Research methods

Records of 744 consecutive patients undergoing first-line curative surgery for HCC in one institution from 2016–2018 were reviewed, and 292 local patients were selected for analysis. General characteristics, CEUS liver imaging reporting and data system (LIRADS) parameters, and serology biomarkers were collected. Univariate analysis and multivariate analyses were performed to evaluate the independent prognostic factors for tumor recurrence. Then, a nomogram called CEUS model was constructed. The CEUS model was then used to predict recurrence at 6 mo, 12 mo, and 24 mo.

Research results

Tumor diameter, preoperative alpha-fetoprotein (AFP) level, and LIRADS were identified to be independent hazard factors, with a hazard ratio of 1.123 (95% confidence interval [CI]: 1.041-1.211), 1.547 (95%CI: 1.245-1.922), and 1.428 (95%CI: 1.059-1.925), separately. A nomogram based on them was constructed; the cut-off value at 6 mo, 12 mo, and 24 mo was 100, 80, and 50, and the C-index was 0.748 (95%CI: 0.683-0.813), 0.762 (95%CI: 0.704-0.820), and 0.762 (95%CI: 0.706-0.819), separately. The calibration at 6 mo was desirable; however, the calibration at 12 and 24 mo should be improved.

Research conclusions

The CEUS model can screen out patients who have a high recurrence risk, it is helpful for making reasonable treatment strategy.

Research perspectives

A multi-center study, with an expanded sample size and prospective verification, is required.
