Primary liver cancer is more aggressive in HIV-HCV coinfection than in HCV infection. A prospective study (ANRS CO13 Hepavih and CO12 Cirvir)

OBJECTIVE: Since HAART, primary liver cancer has emerged as an increasing cause of morbidity and mortality in patients with HIV infection. Our aim was to compare characteristics and outcome of primary liver cancer according to HIV status in HCV cirrhotic patients submitted to periodic ultrasonographic surveillance. METHODS: All patients with primary liver cancer and cirrhosis were selected from two prospective cohorts (ANRS CO12 Cirvir, viral cirrhosis, n=1081; ANRS CO13 Hepavih, HIV-HCV coinfection, n=1175). Cirrhosis was diagnosed by liver biopsy in monoHCV group and biopsy and/or non-invasive tests in HIV-HCV group. Ultrasonographic surveillance was performed every 6 months. Diagnosis of primary liver cancer was established according to EASL-AASLD guidelines. RESULTS: Primary liver cancer was diagnosed in 32 patients, 16 in each group, and corresponded to hepatocellular carcinoma in all except for two cholangiocarcinomas in HIV-HCV patients. Ultrasonographic follow-up was similar (median time since last ultrasonographic without focal lesion: 237 days in HIV-HCV group (n=12) versus 208 days in HCV group, NS). At primary liver cancer diagnosis HIV-HCV patients were markedly younger (48 vs. 60 yrs, P<0.001), primary liver cancer was more advanced in HIV-HCV patients (single nodule: 43% vs. 75%, P=0.07; mean diameter of main nodule: 24 vs. 16 mm, P=0.006; portal obstruction: 3 vs. 0). Curative treatment was performed in four HIV-HCV patients versus 11 HCV patients (P=0.017). During follow-up, 10 HIV-HCV patients died versus only one HCV patient (P=0.0005). CONCLUSIONS: This result suggests more aggressiveness for tumors in HIV infected patients and, if confirmed, could result in shortening the length between ultrasonographic examinations

Oral direct-acting antivirals and the incidence or recurrence of hepatocellular carcinoma:a systematic review and meta-analysis

Background: The influence of direct-acting antiviral (DAA) therapy for chronic hepatitis C virus on the risk of hepatocellular carcinoma (HCC) is conflicting.  Methods: We conducted a systematic review and meta-analysis to determine the incidence or recurrence of HCC associated with oral DAA therapy. We searched PubMed, Scopus, Embase from inception to August 2017 to identify observational studies reporting on HCC among patients treated with DAAs. Two independent reviewers extracted data and assessed the risk of bias. Data were pooled by random-effects model. The primary outcome was the proportion of participants with incidence or recurrence of HCC (PROSPERO number CRD42017057040).  Results: After reviewing 2080 citations, we included 8 controlled studies and 36 uncontrolled studies. The pooled proportion for incident HCC was 1.5 % (95% CI 1.0% to 2.1%; I2=90.1%; n= 542/39 145) from 18 uncontrolled studies and 3.3% (95% CI 1.2% to 9%; I2 =96%; n=109/6909) from 5 controlled studies, respectively. The pooled proportion for recurrent HCC was 16.7% (95% CI 10.2% to 26%; I2=84.8%; n=136/867) from 12 uncontrolled studies and 20.1% (95% CI 5.5% to 52.1%; I2=87.5%; n=36/225) from 3 controlled studies, respectively. There was no statistically significant effect on the risk of recurrent HCC (OR 0.50, 95%CI 0.16 to 1.59; I2 =73.4%) in a meta-analysis of three studies.  Conclusions: Our findings show low proportion of incident HCC, but high proportion of recurrent HCC on treatment with DAAs. Continued active surveillance for HCC after treatment with DAAs remains prudent

Elevated adiponectin and sTNFRII serum levels can predict progression to hepatocellular carcinoma in patients with compensated HCV1 cirrhosis

International audienceAn obesity-related altered adipose tissue secretion is suggested as a risk factor for hepatocellular carcinoma (HCC) in patients with hepatitis C virus (HCV) cirrhosis. However, no prospective study has yet examined the predictive value of circulating adipokines and immuno-inflammatory biomarkers regarding this risk. This was a case-control study nested in a prospective French national cohort of HCV-infected patients with biopsy-proven compensated cirrhosis. We selected 56 HCV1-infected patients who subsequently developed HCC (cases), and 96 controls matched for age, gender and diabetes, not developing HCC after a similar period. Adipokines and immuno-inflammatory biomarkers were determined on baseline frozen serum samples. Their influence on the occurrence of HCC was assessed using a mixed logistic regression model under univariate analysis and a backward stepwise procedure under multivariate analysis. The patients were mostly male (62.5%) with active HCV replication (83%) and had been followed for a median duration of 6.3 years during which 44.4% achieved a sustained viral response. Higher adiponectinemia levels were found in cases than in controls (P = 0.01). Levels of the immuno-inflammatory markers were similar in both groups except sTNFRII &gt;5,000 pg/mL (52% cases versus 24% controls; P = 0.001). No marker was associated with histological steatosis. Under multivariate analysis, baseline adiponectin and sTNFRII levels were independently associated with the occurrence of HCC, alongside previous excessive alcohol intake and HCV viral load. High baseline circulating adiponectin and sTNFRII levels were associated with an increased risk of HCC in patients with HCV1 cirrhosis, independently of their HCV replication status.</p
