| الملخص: | Objective: Improving the prognostic stratification of unresectable hepatocellular carcinoma (HCC) patients is critically needed. Since patients’ survival is closely linked to the severity of the underlying liver disease, and insulin-like growth factor-1 (IGF-1) is produced predominantly in the liver, we hypothesized that IGF-1 may correlate with patients’ survival and hence improve the prognostic ability of the Cancer of the Liver Italian Program (CLIP) score. Methods: Baseline plasma IGF-1 and clinicopathologic parameters were available from 288 patients. Multivariate Cox regression models, Kaplan-Meier curves, and the log-rank test were applied. Recursive partitioning was used to determine the optimal cut point for IGF-1 using training/validation samples. Prognostic ability of the I-CLIP (I = IGF) was compared to CLIP using C-index. Results: IGF-1 significantly correlated with the clinicopathologic features. With an optimal IGF-1 cut point of 26 ng/ml, the overall survival of patients with IGF-1 >26 was 17.7 months (95% CI 13.6–22.8), and with IGF-1 ≤26 was 5.8 months (95% CI 4.0–12.5), p < 0.0001. The concordance probabilities for CLIP and I-CLIP were 0.7037 and 0.7096, respectively (p < 0.0001). Conclusions: Our preliminary results indicate that I-CLIP significantly improved prognostic stratification of patients with advanced HCC. However, independent validation of our study is warranted. |
