A Novel Post-Operative ALRI Model Accurately Predicts Clinical Outcomes of Resected Hepatocellular Carcinoma Patients.

BACKGROUND: Hepatocellular carcinoma (HCC) is one of the leading malignant tumors worldwide. Prognosis and long-term survival of HCC remain unsatisfactory, even after radical resection, and many non-invasive predictors have been explored for post-operative patients. Most prognostic prediction models were based on preoperative clinical characteristics and pathological findings. This study aimed to investigate the prognostic value of a newly constructed nomogram, which incorporated post-operative aspartate aminotransferase to lymphocyte ratio index (ALRI). METHODS: A total of 771 HCC patients underwent radical resection from three medical centers were enrolled and grouped into the training cohort (n = 416) and validation cohort (n = 355). Prognostic prediction potential of ALRI was assessed by receiver operating curve (ROC) analysis. The Cox regression model was used to identify independent prognostic factors. Nomograms for overall survival (OS) and disease-free survival (DFS) were constructed and further validated externally. RESULTS: The ROC analysis ranked ALRI as the most effective prediction marker for resected HCC patients, with the cut-off value determined at 22.6. Higher ALRI level positively correlated with larger tumor size, higher tumor node metastasis (TNM) stage, and inversely with lower albumin level and shorter OS and DFS. Nomograms for OS and DFS were capable of discriminating HCC patients into different risk-groups. CONCLUSIONS: Post-operative ALRI was of prediction value for HCC prognosis. This novel nomogram may categorize HCC patients into different risk groups, and offer individualized surveillance reference for post-operative patients.

Preoperative Gadoxetic Acid-Enhanced MRI Based Nomogram Improves Prediction of Early HCC Recurrence After Ablation Therapy.

PURPOSE: This study aimed to identify preoperative gadoxetic acid-enhanced MRI features and establish a nomogram for predicting early recurrence (≤ 2 years) of hepatocellular carcinoma (HCC) after ablation therapy. METHODS: A total of 160 patients who underwent gadoxetic acid-enhanced MRI and ablation HCC therapy from January 2015 to June 2018, were included retrospectively and divided into a training cohort (n = 112) and a validation cohort (n = 48). Independent clinical risk factors and gadoxetic acid-enhanced MRI features associated with early recurrence were identified by univariate and multivariate logistic regression analysis and used for construction of a nomogram. The performance of the nomogram was evaluated by discrimination, calibration, and clinical utility. RESULTS: Alpha-fetoprotein (AFP) level, tumor number, arterial peritumoral enhancement, satellite nodule and peritumoral hypointensity at hepatobiliary phases in the training cohort were identified as independent risk factors for early recurrence after ablation. A new nomogram that was constructed with these five features showed an area under the curve (AUC) of 0.843 (95%CI 0.771-0.916) and 0.835 (95%CI 0.713-0.956) in the training and validation cohort, respectively. The calibration curve and decision curve analysis (DCA) suggested that the nomogram had good consistency and clinical utility. CONCLUSIONS: A new nomogram that was constructed using four preoperative gadoxetic acid-enhanced MRI features and serum AFP level can predict the risk of early HCC recurrence after ablation therapy with AUC up to 0.843. The strong performance of this nomogram may help hepatologists to categorize patients' recurrent risk to guide selecting treatment options and improve postoperative management.

Effect of Pegylated Interferon Plus Tenofovir Combination on Higher Hepatitis B Surface Antigen Loss in Treatment-naive Patients With Hepatitis B e Antigen -positive Chronic Hepatitis B: A Real-world Experience.

PURPOSE: The loss of serum hepatitis B surface antigen (HBsAg) in patients with chronic hepatitis B (CHB) is considered an ideal clinical outcome but rarely achieved with current standard of care. We evaluated the effectiveness in inducing HBsAg seroclearance in a real-world clinical cohort of Chinese patients with CHB treated with a combination of pegylated interferon (Peg-IFN) with tenofovir disoproxil fumarate (TDF) or monotherapy with each agent. METHODS: A total of 330 patients with CHB were assigned to receive Peg-IFN plus TDF for 48 weeks (Peg-IFN plus TDF group), Peg-IFN alone for 48 weeks (Peg-IFN group), or TDF alone for 144 weeks (TDF group). The primary end point was the percentages of patients who achieved HBsAg seroclearance at week 72. Differences from the baseline characteristics and treatment data were compared using the χ2 test for categorical variables or 1-way ANOVA for continuous variables. A Kaplan-Meier test was performed to compare the HBsAg loss among the 3 groups. Discrimination of responders versus nonresponders was quantified using AUC curves. Optimal cut-offs were selected based on Youden's J statistic defined as J = sensitivity + specificity-1. FINDINGS: At week 72, the Kaplan-Meier cumulative HBsAg loss was 11.5% in the Peg-IFN plus TDF group, 5.7% in the Peg-IFN group, and 0% in the TDF group. The percentage of patients with HBsAg loss was comparable in the Peg-IFN plus TDF and Peg-IFN groups (P = 0.143), but both were significantly higher than that in the TDF group (P = 0.000 and P = 0.010). In addition, a significantly higher percentage of patients in the combination group and Peg-IFN group had serum HBsAg of <100 IU/mL compared with the TDF group (32.7% vs 23.6% vs 9.2%; P < 0.001) but no significant differences in the percentages of patients with HBsAg <1000 IU/mL, the undetectable serum HBV DNA and hepatitis B e antigen seroconversion. Our model predicted serum HBsAg loss at week 72 (AUC = 0.846) if the HBsAg level was reduced by > 1.5 log10 IU/mL from baseline at treatment week 24, an optimal timepoint for prediction of HBsAg loss in this cohort. IMPLICATIONS: A 48-week course of Peg-IFN and TDF combination therapy led to profound reduction in serum HBsAg level, resulting in a significantly higher rate of HBsAg loss compared with TDF monotherapy. Patients with steep HBsAg decline >1.5 log10 IU/mL at week 24 well signaled a higher probability of achieving HBsAg loss at week 72.

[Incidence and characteristics of benign liver space-occupying mass in 17 721 patients with chronic hepatitis B: a color Doppler ultrasound-based case-control study].

OBJECTIVE: To analyze the incidence and risk factors of benign liver space-occupying mass in patients with chronic hepatitis B (CHB) and the ultrasound features that differentiate these masses from small hepatocellular carcinoma. METHODS: We retrospectively analyzed the color Doppler and clinical data of 17 721 patients with CHB treated in the Hepatology Unit of Nanfang Hospital between January, 2016 and December, 2017. The data were compared with those of 21629 healthy control subjects undergoing routine physical examination in the Center of Heath Management of Nanfang Hospital during the same period. RESULTS: Compared with the control subjects, the patients with CHB had significantly higher incidences of hepatic cysts (11.8% vs 8.7%, P < 0.05), hepatic hemangioma (8.2% vs 1.6%, P < 0.05) and hepatic cirrhosis nodules (20.6% vs 2.4%, P < 0.05). The incidences of hepatic cysts and cirrhosis nodules increased with age and was significantly higher in male than in female patients (P < 0.001). The highest incidence of hepatic hemangioma was found in CHB patients aged 30-49 years without a gender difference (P>0.05). Sonographically, the benign liver masses commonly showed homogeneous echo within the lesion with clear boundaries and regular shape. Hepatic hemangioma was distinctively hyperechoic in 83.32% (1579/1895) of the patients, while small hepatocellular carcinoma presented with weaker peripheral and internal blood flow signals with a lower flow velocity in the arteries and a higher flow velocity in the portal vein. Liver cirrhosis nodules mostly showed a mixture of strong and weak echoes (79.60%; 7637/9595) without blood flow signal within or around the nodule; an increased volume of the nodule accompanied by heterogeneous echoes within the nodule indicated an increased probability of malignant lesion. Hepatic cysts often displayed no echo within the lesion, but the echo could be enhanced posteriorly. CONCLUSIONS: The patients with CHB are at a significantly higher risk of developing hepatic cysts, hepatic hemangiomas and hepatic cirrhosis nodules than the control population, and an older age and the male gender are associated with a higher incidence of hepatic cysts or cirrhosis. The differences in the sonographic and hemodynamic features can help to differentiate hepatic benign mass from malignant lesions, and kinetic changes in sonography can be used to monitor potential malignant transformation of the cirrhotic lesions.

[Antiviral and antifibrotic therapies reduce occurrence of hepatocellular carcinoma in patients with chronic hepatitis B and liver fibrosis: a 144-week prospective cohort study].

OBJECTIVE: To compare the efficacy and safety of different antiviral and antifibrotic regimens in patients with chronic hepatitis B (CHB) and hepatic fibrosis and the incidence of hepatocellular carcinoma (HCC) associated with these therapies. METHODS: A total of 840 patients with CHB and concurrent hepatic fibrosis, who received antiviral therapy in Nanfang Hospital between June, 2010 and June, 2018, were enrolled in this follow-up cohort study. The patients were assigned to 3 cohorts matched for gender, age (difference≤5 years), HBeAg status and liver stiffness measurement (LSM) for treatment with one of the 3 antiviral drugs, namely entecavir, tenofovir dipivoxil and adefovir dipivoxil; each cohort was divided into 2 groups, with one of the groups having a combined treatment with Fufang Biejiaruangan tablet. The cumulative negative conversion rate of HBV DNA, normalization rate of ALT, hepatic fibrosis regression and the incidence of HCC were compared among the 3 cohorts and across the 6 groups at 144 weeks. RESULTS: A total of 749 patients were available to follow-up at 144 weeks. Compared with the baseline data, the cumulative negative conversion rate of HBV DNA increased gradually and the abnormal rate of ALT decreased significantly over time during the treatment in all the 6 groups (all P < 0.001). Compared with the any of the antiviral drugs used alone, the combined treatments all resulted in significantly better antifibrotic effects (χETV cohort2=11.345, χTDF cohort2=10.160, χADV cohort2=6.358; all P < 0.05). At 144 weeks, the incidence of HCC were 2.2%, 1.7%, 1.7% and 3.3% in enecavir group, enecavir with Biejiaruangan tablet group, adefovir group, and adefovir with Biejiaruangan tablet group, respectively, showing no significant difference between the two cohorts (4 groups; χ2=6.813, P=0.138). None of the patients in the 2 groups with tenofovir treatment had HCC by the end of the observation. CONCLUSIONS: Antiviral therapy combined with antifibrotic therapy can effectively reverse hepatic fibrosis and reduce the incidence of HCC in patients with CHB; among the 3 antiviral drugs, tenofovir dipivoxil can be a better option for reducing the incidence of HCC in these patients.
