Clinical features and outcomes of hepatocellular carcinoma in Caucasian cirrhotic patients on long-term analogue therapy for hepatitis B

Italian Association for the Study of the Liver (AISF). Portal Hypertension and Ascites: Patient-and Population-centered Clinical Practice Guidelines by the Italian Association for the Study of the Liver (AISF)

Portal hypertension and ascites are two crucial events in the natural history of liver cirrhosis, whose appearance marks a downward shift in the prognosis of the disease. Over the years, several international and national societies have issued clinical practice guidelines for the diagnosis and management of portal hypertension and ascites. The present document addresses the needs of an updated guidance on the clinical management of these conditions. Accordingly, the AISF Governing Board appointed a multi-disciplinary committee of experts for drafting an update of the most recent EASL Clinical Practice Guidelines. The aim of this work was to adapt the EASL recommendations to national regulations and resources, local circumstances and settings, infrastructure, and cost/benefit strategies to avoid duplication of efforts and optimize resource utilization. The committee defined the objectives, the key issues and retrieved the relevant evidence by performing a systematic review of the literature. Finally, the committee members (chosen on the basis of their specific expertise) identified the guidelines' key questions and developed them following the PICO format (Population, Intervention, Comparison, Outcomes). For each of the PICO questions, the systematic review of the literature was made on the most important scientific databases (Pubmed, Scopus, Embase).

Clinical features of hepatocellular carcinoma with hepatitis B virus among patients on Nucleos(t) ide analog therapy

Background

The clinical manifestation of hepatocellular carcinoma (HCC) with hepatitis B virus (HBV) varies significantly between patients treated with or without nucleos(t) ide analog (NUC) therapy. To have a better understanding of HCC with HBV, we compared the clinical features of patients with HCC receiving or not receiving NUC therapy.

Methods

We retrospectively reviewed the medical records of 76 patients with HBV-caused HCC who received treatment at the Hunan Provincial Peoples' Hospital starting from January 1, 2008 to December 31, 2017. They were categorized into two groups, namely, NUC group and non-NUC group, based on whether they had received NUC therapy or not.

Results

The percentage of liver pain (36.36% vs. 79.07%; p < 0.05) and appetite loss (30.30% vs. 70.27%; p < 0.05) in the NUC group was lower than that in the non-NUC group. We observed a similar trend for the percentage of undetectable HBV-DNA (11.63% vs. 63.64%; p < 0.05) and normal ALT (25.58% vs. 75.76%; p < 0.05) between non-NUC and NUC groups. There were no significant differences between the two groups with respect to TBiL (p = 0.370) and ALB (p = 0.475). The same trend was observed for the proportion of HBeAg negative (p = 0.719) and AFP ≤ 14.65 ng/mL (p = 0.199) in both groups. Single tumor nodule was more common in the NUC group compared to the non-NUC group (66.67% vs. 6.98%; p < 0.05). An opposite trend was observed for portal vein invasion (18.18% vs. 79.07%; p < 0.05) and metastasis (0% vs. 44.19%; p < 0.05).

Conclusions

Nucleos(t) ide analog therapy exerts a significant impact on the clinical and radiological characteristics of hepatocellular carcinoma with HBV. Patients receiving nucleos(t) ide analog therapy were found to have milder symptoms and fewer radiographic findings.

High risk of clinical events in untreated HBeAg-negative chronic hepatitis B patients with high viral load and no significant ALT elevation

BACKGROUND

It remains unknown whether antiviral treatment for HBeAg-negative chronic hepatitis B (CHB) patients having high viral loads without significant elevation of alanine aminotransferase (ALT) levels would reduce the risks of clinical events.

AIM

To compare clinical outcomes of high viral load CHB patients untreated for normal or mildly elevated ALT vs those treated for ALT ≥ 2 upper limit of normal (ULN).

METHODS

This historical cohort study included 5414 HBeAg-negative CHB patients without cirrhosis at a tertiary hospital in Korea from 2000 to 2013. Inactive phase was defined as serum hepatitis B virus [HBV] DNA < 2000 IU/mL and persistently normal ALT (n = 3572). High viral load (HBV DNA ≥ 2000 IU/mL) patients were classified into three phases by ALT levels: Replicative (persistently normal ALT, n = 900); Mildly active (ALT 1-2ULN, n = 396); and Active (ALT ≥ 2ULN, n = 546) phases. All Active phase patients were treated with nucleos(t)ide analogues.

RESULTS

The mean age of the patients was 47 years without a significant difference among the groups. Compared with the treated Active phase group, the untreated Replicative phase group showed a significantly higher risk of hepatocellular carcinoma (HCC; HR 1.76; 95% CI 1.00 - 3.10, P = 0.05) and death/transplantation (HR 2.14; 5% CI 1.09 - 4.21, P = 0.03) by propensity score-matched analysis. The untreated mildly active phase patients had further increase in risk of HCC and death/transplantation compared with the treated Active phase group by unadjusted, PS-matched, competing risks, and multivariable-adjusted analyses.

CONCLUSIONS

Untreated high viral load HBeAg-negative CHB patients without significant ALT elevation had higher risks of clinical events than treated Active phase patients with elevated ALT.

Non-virological factors are drivers of hepatocellular carcinoma in virosuppressed hepatitis B cirrhosis: Results of ANRS CO12 CirVir cohort

Worldwide, hepatocellular carcinoma (HCC) occurs mainly in Asian patients with hepatitis B virus (HBV) infection. This study aimed to decipher the environmental and virological factors associated with HCC occurrence and validate risk scoring systems in a French multicentre prospective cohort of HBV cirrhotic patients. Patients with biopsy-proven Child-Pugh A viral cirrhosis included in the ANRS CO12 CirVir cohort who were HBsAg(+) without hepatitis C coinfection were selected for: (a) interview through a standardized questionnaire reporting coffee consumption and HCC familial history; (b) HBsAg quantification using baseline and sequential 2-year frozen sera; (c) baseline HBV genotype determination; and (d) assessment of risk factors and applicability of HCC risk scores (Kaplan-Meier analysis, Cox models). Among 317 patients studied (261 men, median age 53 years, past or ongoing antiviral treatment 93.3% and baseline detectable HBV DNA in 88 patients), the baseline and 2-year median HBsAg levels were 810 and 463 IU/mL, respectively. After a median follow-up of 65.2 months, 27 HCC cases were diagnosed (annual incidence: 1.6%). Three factors were independently associated with HCC occurrence: age > 50 years, platelets ≤ 150 × 10³ /mm³ and body mass index ≥ 30 kg/m² . Two out of five risk scores were validated, and the most accurate was PAGE-B at 1 year. Moreover, HCC in patients without maintained virological suppression seems more aggressive and less accessible to curative treatment. In conclusion, in French patients with HBV cirrhosis mostly virally suppressed, independent HCC risk factors were host-related (age, obesity) or linked to the severity of cirrhosis (thrombopenia), and the European PAGE-B score was the most accurate risk score.
