Validation of the Toronto hepatocellular carcinoma risk index for patients with cirrhosis in China: a retrospective cohort study
Abstract Background The Toronto hepatocellular carcinoma (HCC) risk index (THRI) was developed to predict HCC in patients with cirrhosis. This study aimed to validate the THRI in a 10-year Asian cohort. Methods A total of 2836 patients with cirrhosis at the First Affiliated Hospital of Soochow Unive...

This study aimed to validate the THRI in a 10-year Asian cohort. Methods A total of 2836 patients with cirrhosis at the First Affiliated Hospital of Soochow University between January 2008 and May 2018 were evaluated. Based on the THRI value at diagnosis, patients were divided into three groups (< 120, low-risk; 120–240, intermediate-risk; > 240, high-risk). Student’s t test and Fisher’s exact test were applied to compare parameters between the HCC group and the non-HCC group. The receiver operator characteristic (ROC) curve was drafted to identify the value of the THRI in predicting HCC. Logistic regression was utilized to assess the relationship between the development of HCC and THRI values. The incidence of HCC was calculated for the three groups using the Kaplan-Meier method, and curves were compared using the log-rank test. Results Of 520 patients enrolled in this study, 76 patients developed HCC. Patients who developed HCC had a higher THRI score than those who did not develop HCC (279.5 ± 57.1 vs. 232.3 ± 67.6, respectively, p < 0.001). The area under the ROC curve for the THRI to predict HCC was 0.707 ([95% CI 0.645–0.769], p < 0.001), with a sensitivity of 0.842 and a specificity of 0.486 when the cutoff THRI value was 226. Compared to the low-risk group, the high-risk group presented higher odds of developing HCC (adjusting odds ratio 1.026 [95% CI 1.002–1.051], p = 0.036). Differences existed in the cumulative incidence of HCC among the three risk groups (log-rank, p < 0.001). The 5-year cumulative HCC incidence of the low-risk group, intermediate-risk group, and high-risk group was 0%, 13%, and 34%, respectively. Conclusion This study validated THRI values for predicting HCC in Asians with cirrhosis, which presented a fine sensitivity to identify the high-risk population of HCC for secondary prevention.http://link.springer.com/article/10.1186/s12957-019-1619-3CirrhosisHepatocellular carcinoma (HCC)Toronto hepatocellular carcinoma risk index (THRI)Validation |
