Abstract Early recurrence of hepatocellular carcinoma (HCC) is implicated in poor patient survival and is the major obstacle to improving prognosis. The current staging systems are insufficient for accurate prediction of early recurrence, suggesting that additional indicators for early recurrence are needed. Here, by analyzing the gene expression profiles of 12 Gene Expression Omnibus data sets (n = 1533), we identified 257 differentially expressed genes between HCC and non-tumor tissues. Least absolute shrinkage and selection operator regression model was used to identify a 24-messenger RNA (mRNA)-based signature in discovery cohort GSE14520. With specific risk score formula, patients were divided into high- and low-risk groups. Recurrence-free survival within 2 years (early-RFS) was significantly different between these two groups in discovery cohort [hazard ratio (HR): 7.954, 95% confidence interval (CI): 4.596–13.767, P < 0.001], internal validation cohort (HR: 8.693, 95% CI: 4.029–18.754, P < 0.001) and external validation cohort (HR: 5.982, 95% CI: 3.414–10.480, P < 0.001). Multivariable and subgroup analyses revealed that the 24-mRNA-based classifier was an independent prognostic factor for predicting early relapse of patients with HCC. We further developed a nomogram integrating the 24-mRNA-based signature and clinicopathological risk factors to predict the early-RFS. The 24-mRNA-signature-integrated nomogram showed good discrimination (concordance index: 0.883, 95% CI: 0.836–0.929) and calibration. Decision curve analysis demonstrated that the 24-mRNA-signature-integrated nomogram was clinically useful. In conclusion, our 24-mRNA signature is a powerful tool for early-relapse prediction and will facilitate individual management of HCC patients.

Abstract Background The effect of putative factors on the clinical course of early hepatocellular carcinoma (HCC) after primary surgical or nonsurgical curative treatment, which remains elusive, was quantified. Methods Patients with newly diagnosed early HCC who received surgical resection (SR) or percutaneous radiofrequency ablation (RFA) with or without transcatheter arterial chemoembolization (TACE) from January 2003 to December 2016 were enrolled. The cumulative overall survival (OS) and disease-free survival (DFS) were compared. A polytomous logistic regression was used to estimate factors regarding early and late recurrence. Independent predictors of OS were identified using Cox proportional hazard regression. Results One hundred twenty-five patients underwent SR, and 176 patients underwent RFA, of whom 72 were treated with TACE followed by RFA. Either match analysis based on propensity score or multiple adjustment regression showed no significant difference in DFS and OS between the two groups. Multivariate analysis showed high AFP (>= 20 ng/mL), and multinodularity significantly increased risk of early recurrence (<=1year). In contrast, hepatitis B virus, hepatitis C virus and multinodularity were significantly associated with late recurrence (>1year). Multivariate Cox regression with recurrent events as time-varying covariates identified older age (HR=1.55, 95% CI:1.01-2.36), clinically significant portal hypertension (CSPH) (HR=1.97, 95% CI:1.26-3.08), early recurrence (HR=6.62, 95% CI:3.79-11.6) and late recurrence (HR=3.75, 95% CI:1.99-7.08) as independent risk factors of mortality. A simple risk score showed fair calibration and discrimination in early HCC patients after primary curative treatment. In the Barcelona Clinic Liver Cancer (BCLC) stage A subgroup, SR significantly improved DFS comparing to those received RFA with or without TACE. Conclusion Host and tumor factors rather than the initial treatment modalities determine the outcomes of early HCC after primary curative treatment. Statistical models based on recurrence types can predict early HCC prognosis but further external validation is necessary.

Hepatocellular carcinoma (HCC) is one of the most frequent malignant tumors and an important cause of death. It has become evident that the tumor microenvironment, including hypoxia, plays a major role in the development of HCC. This paper focuses on the role of chronic hypoxia in HCC. Recently, we have shown the importance of chronic hypoxia on gene expression and behavior of liver cells. Using a cell culture model, we identified a distinct gene expression pattern and demonstrated clinical relevance for a 7-gene subset that can predict survival and early recurrence in patients. Recently, it was also shown that chronic hypoxia is associated with the upregulation of β-catenin and Hif1α and that suppression of β-catenin reduced the metastatic potential of the tumor. Both studies demonstrate the importance of chronic hypoxia for the prognosis of HCC. Identifying the molecular pathways can help us to understand the mechanisms responsible for tumor aggressiveness.

Neither match analysis based on propensity score nor multiple adjustment regression yielded a significant difference in DFS and OS between the two groups. Multivariate analysis showed high AFP (> 20 ng/mL), and multinodularity significantly increased risk of early recurrence (< 1 year). In contrast, hepatitis B virus, hepatitis C virus and multinodularity were significantly associated with late recurrence (> 1 year). Multivariate Cox regression with recurrent events as time-varying covariates identified older age (HR = 1.55, 95% CI:1.01–2.36), clinically significant portal hypertension (CSPH) (HR = 1.97, 95% CI:1.26–3.08), early recurrence (HR = 6.62, 95% CI:3.79–11.6) and late recurrence (HR = 3.75, 95% CI:1.99–7.08) as independent risk factors of mortality.
