BACKGROUND Conventional transarterial chemoembolization (cTACE) with lipiodol is widely performed in patients with hepatocellular carcinoma (HCC) unsuitable for curative treatment. Additional tumor parameters such as HCC macroscopic appearance based on imaging might be helpful for transarterial chemoembolization prognostication and management. PATIENTS AND METHODS A total of 405 patients with HCC who underwent cTACE between 2008 and 2016 from a real-life multicenter French cohort were retrospectively reviewed. Tumors were classified into two macroscopic types according to HCC gross appearance on imaging: nodular versus non-nodular. The study population was stratified into two groups: derivation and validation cohorts. Independent prognostic factors of survival based on multivariate cox regression models were determined and then assessed in the validation set. Thereafter, time to progression (TTP) and radiological response rate were investigated for each prognostic factors of survival. RESULTS Median overall survival (OS) was 35 months for Barcelona Clinic Liver Cancer (BCLC) stage A, 22 months for BCLC stage B and 12 months for BCLC stage C patients (P < 0.0001). The corresponding TTP for these patients was 12 (7-17) months, 5 (3-6) months and 1.2 (1.2-3) months (P < 0.0001). Multivariate analysis revealed that tumors size and number, non-nodular type, alpha-fetoprotein, aspartate aminotransferase serum levels and impairment of performance status-1 were independent predictors of survival among the study groups. Non-nodular type was the most powerful factor that influences OS, TTP and radiological response rate for the recommended transarterial chemoembolization candidates. TTP was consistent with OS within each stage. CONCLUSION HCC macroscopic appearance on imaging is a determinant predictor of outcome after cTACE in a real-life multicenter cohort.

BACKGROUND Direct-acting antivirals (DAAs) therapy against hepatitis C viral (HCV) infection has markedly improved the sustained viral response. However, recent studies have suggested an unsuspected high rate of hepatocellular carcinoma (HCC) recurrence. PATIENTS AND METHODS A retrospective case-control study was carried out to investigate the impact of DAAs on tumor recurrence in patients with complete response to HCC treatment within our HCV-related cirrhosis cohort. Patients who received [group 1 (G1), n=22] or not [group 2 (G2), n=49] a DAAs therapy were matched 1 : 2 for age, sex, liver function, HCC stage, and treatment. RESULTS Initial HCC were mostly Barcelona Clinic Liver Cancer stage A (95% G1, 94% G2). Sustained viral response with DAAs was achieved in 86% of patients. After a similar median overall follow-up time with similar radiologic surveillance after HCC treatment, 41% of patients developed radiologic tumor recurrence in G1 versus 35% of patients in G2 (P=0.7904). There was no significant difference in time to progression between the two groups [12 (9-16) months G1 vs. 14 (8-21) months G2, P=0.7688], or Barcelona Clinic Liver Cancer stage at recurrence. However, the interval between HCC treatment and antiviral therapy was significantly different among DAAs patients with recurrence and those without recurrence [7.0 (2.5-9.0) months vs. 36.0 (9.0-58.0) months, P=0.0235, respectively]. CONCLUSION In our case-control study, HCV therapy with DAAs does not accelerate or prevent early HCC recurrence compared with untreated patients. The rate of recurrence, time to progression, and HCC pattern are similar. Early DAAs treatment (

Background Advanced hepatocellular carcinoma (HCC) includes a wide spectrum of tumors and patients' prognosis after treatment is highly variable. Moreover, therapeutic options based on the Barcelona Clinic Liver Cancer (BCLC) staging system algorithm are restricted to one systemic therapy. Aim of the study To refine the stratification among BCLC C HCC patients by establishing a new simple prognostic score. Patients and methods A regression model based on a BCLC stage C population and validated with an external cohort of BCLC C HCC patients defined the score. It was therefore validated among three external cohorts of BCLC C HCC patients treated with sorafenib. Results Five variables had independent prognostic values: the number of nodules, the infiltrating nature of the HCC, alpha-fetoprotein serum level, Child-Pugh score, and Eastern Cooperative Oncology Group Performance Status grade. They were integrated into a new score named NIACE ranging from 0 to 7, well correlated with survival. With the use of one threshold value, this score enables defining of two populations with different survivals among BCLC C patients and specifically among those treated with sorafenib. Conclusion The NIACE score defines different prognostic subgroups after palliative treatment of HCC. It could be an additional tool for BCLC C HCC before inclusion in clinical trials or for the management of patients. These results must be validated in a prospective study

BACKGROUND: Recent studies have suggested that host genetics may be useful for predicting drug response and have supported the recommendation that single polynucleotide polymorphisms (SNPs) of IL28B should be investigated when treating hepatitis C virus (HCV)-1 infected patients. The aim of this study was to determine whether a single IL-28B genotype SNP rs8099917 or rs12979860 determination is sufficient to predict treatment failure in patients with chronic HCV. METHODS: A total of 198 patients were included; mean (±standard deviation) age was 47±12 years and 140 (71%) were men. One hundred and fifty-six (79%) patients were infected with HCV genotype 1 and 42 (21%) with HCV genotypes 2 or 3. One hundred and eight (55%) patients had sustained virologic response (SVR). Two SNPs in the IL-28B were analyzed (rs8099917 and rs12979860). RESULTS: A total of 115 (58%) patients had rs8099917 TT genotype and 61 (31%) had rs12979860 CC genotype. Rs8099917 TT and rs12979860 CC genotypes were associated with SVR in HCV genotype 1 patients [odds ratio=2.60 (1.36-5.00), P=0.004 and odds ratio=3.30 (1.58-6.90), P=0.03 respectively]. No association was found between SNPs and SVR in HCV genotype 2 or 3 patients. CONCLUSION: This study confirms that SNPs rs8099917 and rs12979860 used alone may be useful for predicting the outcome of HCV treatment. In a rational and cost-effective approach, determination of only one of these two SNPs is sufficient for predicting SVR. Because of the highest predictive SVR associated with rs12979860 CC compared with the rs8099917 TT (respective positive predictive value: 72% vs. 63%, P=ns), rs12979860 determination alone is sufficient for predicting interferon response.
