A randomized trial of hepatic arterial chemoembolization was conducted in 42 patients with unresectable hepatocellular carcinoma. These patients represented 41% of patients with hepatocellular carcinoma seen during the inclusion period. In the remaining 59%, 9% had resectable tumours and 50% had unresectable tumours with contraindication for chemoembolization. Patients received either repeated chemoembolization with gelfoam powder and doxorubicin (group 1) or symptomatic treatment (group 2). There was no difference in age, prevalence of cirrhosis or staging according to Okuda between the two groups of patients. A complete tumour response (assessed by arteriography, ultrasonography and serum alphafetoprotein) was observed in four patients, and a partial response in three other patients from group 1. Actuarial survival rates were 33 and 24% in group 1 and 52 and 31% in group 2 at 6 and 12 months, respectively (differences were not significant--logrank test). With the treatment used in our study, chemoembolization did not prolong the survival time of patients with unresectable hepatocellular carcinoma. There were, however, some complete or partial responses. The high spontaneous 1-year survival rate of untreated patients was probably due to the exclusion of the most severely ill patients. Our results do not support the use of this method of chemoembolization in the treatment of hepatocellular carcinoma.

A prognostic study based on 127 untreated patients with hepatocellular carcinoma was undertaken to evaluate their survival time and to find clinical and biologic criteria which allow the selection of patients with a survival time longer than 60 days who could enter a therapeutic trial. Twenty‐eight clinical and biologic variables were assessed using univariate and multivariate semiparametric regression (Coxs) models. Ten variables were isolated by univariate analysis. Multivariate analysis found a negative relationship between a survival time longer than 60 days and five of these variables; these variables were in decreasing order: encephalopathy, alcohol consumption, aspartate amino transferase (AST), blood urea nitrogen, and total bilirubin. Prevalence, positive, and negative predictive values of encephalopathy were 20%, 27.5%, and 97% respectively. When three other criteria: ASAT > four times the upper limit of the normal (N), blood urea nitrogen > N, and total bilirubin > 2N were added, their prevalence, positive, and negative predictive values were 72%, 89.7%, and 57.1% respectively. These results suggest that in countries where incidence of hepatocellular carcinoma is low and recruitment of patients difficult, absence of encephalopathy must be the only criterion for selection of patients with hepatocellular carcinoma in therapeutic trials; whereas, in countries with a high incidence of hepatocellular carcinoma the other criteria may be added.

The clinical signs and symptoms, the biological data and the prognosis of 38 cirrhotic patients with culture-positive spontaneous bacterial peritonitis and 15 cirrhotic patients with culture-negative neutrocytic ascites were compared. The diagnosis of culture-negative neutrocytic ascites was based on the following criteria: an ascitic fluid polymorphonuclear count greater than 250/mm3, a negative ascitic fluid culture and the absence of previous antibiotic therapy and intraabdominal source of infection. All patients were treated by antibiotic therapy. There were no differences in clinical signs and symptoms and Pugh grading between the two groups of patients. Serum creatinine and prevalence of positive-blood culture were higher in spontaneous bacterial peritonitis. Patients with culture-positive spontaneous bacterial peritonitis had a higher ascitic fluid polymorphonuclear count and a lower ascitic fluid pH. Mortality was higher in patients with culture-positive spontaneous bacterial peritonitis than in patients with culture-negative neutrocytic ascites (relative risk: 2.6, p less than 0.01): cumulative mortality was, respectively, 50% and 20% at 1 months, 61% and 33% at 6 months, 75% and 41% at 1 year. The higher mortality observed in patients with culture-positive spontaneous bacterial peritonitis persisted after hospitalization (relative risk: 3, p less than 0.03). Our results suggest that culture-negative neutrocytic ascites is a less severe variant of spontaneous bacterial peritonitis.

Topical antifungal treatments are recommended but rarely used as first‐line therapy for oropharyngeal candidiasis (OPC) in patients with cancer. Miconazole Lauriad 50‐mg mucoadhesive buccal tablet (MBT) Loramyc reportedly delivered rapid and prolonged, effective concentrations of miconazole in the mouth. The objective of the current study was to compare MBT with miconazole 500‐mg oral gel (MOG) in patients with head and neck cancer.

The aim of this work was to develop an individualized score for predicting hepatocellular carcinoma (HCC) in patients with hepatitis C (HCV)‐compensated cirrhosis. Among 1,323 patients with HCV cirrhosis enrolled in the French prospective ANRS CO12 CirVir cohort, 720 and 360 were randomly assigned to training and validation sets, respectively. Coxs multivariate model was used to predict HCC, after which a nomogram was computed to assess individualized risk. During follow‐up (median, 51.0 months), 103 and 39 patients developed HCC in the training and validation sets, respectively. Five variables were independently associated with occurrence of HCC: age > 50 years (hazard ratio [HR], 1.94; 95% confidence interval [CI], 1.16; 3.25; P = 0.012); past excessive alcohol intake (HR, 1.55; 95% CI, 1.02; 2.36; P = 0.041); low platelet count (<100 Giga/mm3: HR, 2.70; 95% CI, 1.62; 4.51; P < 0.001; [100; 150] Giga/mm3: HR, 1.87; 95% CI, 1.10; 3.18; P = 0.021); gamma‐glutamyl transpeptidase above the upper limit of normal (HR, 1.96; 95% CI, 1.11; 3.47; P = 0.021); and absence of a sustained virological response during follow‐up (HR, 3.02; 95% CI, 1.67; 5.48; P < 0.001). An 11‐point risk score was derived from the training cohort and validated in the validation set. Based on this score, the population was stratified into three groups, in which HCC development gradually increased, from 0% to 30.1% at 5 years for patients with the lowest (≤3) and highest (≥8) scores (P < 0.001). Using this score, a nomogram was built enabling individualized prediction of HCC occurrence at 1, 3, and 5 years. Conclusion: This HCC score can accurately predict HCC at an individual level in French patients with HCV cirrhosis. (Hepatology 2016;64:1136‐1147)

Objective To assess incidence and prognostic significance of bacterial infections (BIs) occurring in compensated viral cirrhosis. Design This prospective study involved 35 French centres. Inclusion criteria were biopsy-proven HCV or HBV cirrhosis, Child–Pugh A and no previous hepatic complications. Cumulative incidence (CumI) of events was estimated in a competing risks framework. Results 1672 patients were enrolled (HCV 1323, HBV 318, HCV-HBV 31). During a median follow-up of 43 months, 234 BIs occurred in 171 patients (5 year CumI: 12.9%), among whom 14.6% had septic shock. Main localisations included the urinary tract (27.4%), lung (25.2%) and peritoneum (10.7%) (other, 86 (36.7%)). Most BIs occurred as a first event prior to liver decompensation (n=140, 81.8%) and were community-acquired (CA, 84.2%). The risk of BI was higher in patients with HCV than in patients with HBV (5 year CumI: 15.2% vs 5.5%, p=0.0008). Digestive localisation, concomitant interferon-based treatment, isolation of resistant bacteria and non-CA BIs were associated with lowest probability of resolution. The occurrence of a first BI impaired survival in patients infected with HCV (5 year survival: 60.2% vs 90.4%, p<0.001) and patients infected with HBV (5 year survival: 69.2% vs 97.6%, p<0.001). BIs represented the third cause of death (14.1%) after liver failure and liver cancer. BI risk factors comprised older age, lower albumin, proton pump inhibitor intake and absence of virological eradication/control. Conclusion BI mostly occurs as a first complication and represents a turning point in the course of compensated viral cirrhosis. Its occurrence impacts long-term prognosis and may define a subgroup of patients in whom adaptation of management is warranted.

Hepatocellular carcinoma (HCC) is the fifth most common cancer in men (523 000 cases) and the seventh in women (226 000 cases). Most of the burden is in developing countries, where almost 85% of the cases occur, and particularly in men: the overall sex ratio male/female is around 4. High incidence r...

Background Doxorubicin Transdrug (DT), a nanoformulation of doxorubicin, was demonstrated to overcome the chemoresistance of hepatocellular carcinoma (HCC) in preclinical models. Its efficacy and safety were thus investigated in phase I and randomised phase II trials in unresectable HCC. Patients and methods Phase I was a single dose of DT through the hepatic intra-arterial (HIA) route, dose-escalating 3+3 trial, evaluating five-dose levels from 10 to 40 mg/m2 with maximal tolerated dose (MTD) as primary endpoint. The multicentre phase II trial randomly assigned (2:1 ratio) patients to receive either 30 mg/m2 of DT through HIA route every 4 weeks for up to three courses or best standard of care (BSC). Progression-free survival (PFS) rate at 3 months was the primary endpoint. Overall survival (OS) and disease control rate (DCR) were secondary endpoints. Results In phase I, haematological and respiratory limited toxicities were reported at 35 and 40 mg/m2, giving MTD at 30 mg/m2. Partial response rate was 10%, and stable disease 70%. Phase II was discontinued due to three severe acute respiratory distress events in the DT group while 17 patients had received 30 mg/m2 DT and 11 BSC. At 3 months, PFS was 64% (95% CI 31 to 89) vs 75% (95% CI 35 to 97), and DCR 35% vs 27% in DT and BSC, respectively (p=NS). Median OS was 32.6 months (95% CI 8.2 to 34.1) in DT group and 15 months (95% CI 8.0 to 18.8) in BSC group (p<0.05). Conclusion DT increased OS in unresectable HCC but induced severe respiratory distress. Efficacy data deserve further investigation using a safer dosing and schedule regimen.

Data on extrahepatic cancers (EHCs) in compensated viral cirrhosis are limited. The objective of the prospective multicenter Agence Nationale de Recherche sur le SIDA et les Hépatites virales CO12 CirVir cohort was to assess the occurrence of all clinical events in patients with compensated viral cirrhosis, including all types of cancer. Patients with the following inclusion criteria were enrolled in 35 French centers: (1) biopsy‐proven hepatitis B virus (HBV) or hepatitis C virus (HCV) cirrhosis, (2) Child‐Pugh A, or (3) absence of previous liver complications including primary liver cancer (PLC). Patients were followed up prospectively every 6 months. The standardized mortality ratio (SMR) was calculated according to age and gender using 5‐year periods. The impact of sustained viral response (SVR) in HCV patients and maintained viral suppression in HBV patients were assessed using time‐dependent analysis. A total of 1,671 patients were enrolled between 2006 and 2012 (median age, 54.9 years; men, 67.3%; HCV, 1,323; HBV, 317; HCV–HBV, 31). Metabolic features and excessive alcohol and tobacco consumption were recorded in 15.2%, 36.4%, and 56.4% of cases, respectively. After a median follow‐up of 59.7 months, 227 PLCs were diagnosed (5‐year cumulative incidence [CumI] 13.4%) and 93 patients developed EHC (14 patients with lymphoid or related tissue cancer and 79 with solid tissue cancer; 5‐year EHC CumI, 5.9%). Compared to the general French population, patients were younger at cancer diagnosis, with significantly higher risk of EHC in HCV patients (SMR, 1.31; 95 confidence interval [CI], 1.04‐1.64; P = 0.017) and after SVR (SMR = 1.57; 95% CI, 1.08‐2.22; P = 0.013). EHC was the fourth leading cause of death in the whole cohort and the first in patients with viral control/eradication. Conclusion: Compared to the general French population, HCV cirrhosis is associated with a higher risk of EHC and the first cause of death in patients with viral cirrhosis who achieve virological control/eradication.

Background The objective was to examine the role of a sustained virological response (SVR) on major adverse cardiovascular events (MACEs) in patients with compensated hepatitis C virus (HCV) cirrhosis. Methods Patients with the following criteria were enrolled in 35 French centers: (1) biopsy‐proven HCV cirrhosis; (2) Child‐Pugh A; (3) positive viremia; and (4) no prior liver complication, and then prospectively followed. All patients received HCV treatment after inclusion. MACEs included stroke, myocardial infarction, ischemic heart disease, heart failure, peripheral arterial disease, cardiac arrest, and cardiovascular death. SVR, defined as negative viremia 12 weeks posttreatment, was considered as a time‐dependent covariate, and its effect on MACE occurrence was assessed. The median follow up was 57.5 months, ending in December 2015. Results Sixty‐two of 878 (7.1%) patients presented a total of 79 MACEs. The main predictive baseline factors of MACEs were Asian ethnic origin, history of MACEs, arterial hypertension, diabetes mellitus, current smoking, low serum albumin level, high total bilirubin level, and low platelet count. In multivariate analysis, SVR was associated with a decreased risk of MACEs (hazard ratio = 0.35, 95% CI 0.09‐0.97, P = .044), whereas Asian ethnic origin, arterial hypertension, smoking, and low serum albumin level remained predictive of MACE occurrence. The 5‐year survival rate was 60.1% versus 87.5% in patients who did versus those who did not present a MACE (P < .001). Conclusions In patients with compensated HCV‐related cirrhosis, Asian ethnic origin, arterial hypertension, smoking, and low serum albumin are independent predictive factors of cardiovascular events, whereas an SVR is associated with a decreased rate of cardiovascular events.
