RESUMO

INTRODUCTION AND OBJECTIVES: Different patterns of liver injury have been reported in association with the SARS-CoV-2 vaccines. The aim of this study was to describe a nationwide cohort of patients with SARS CoV-2 vaccine-induced liver injury, focusing on treatment and the evolution after further booster administration. PATIENTS AND METHODS: multicentre, retrospective-prospective study, including subjects who developed abnormal liver tests within 90 days after administration of SARS-CoV-2 vaccination. RESULTS: 47 cases were collected: 17 after prime dose and 30 after booster. Age was 57 years, 30 (63.8 %) were female, and 7 (14.9 %) had a history of prior autoimmune hepatitis (AIH). Most cases were non-severe, though 9 (19.1 %) developed acute liver injury or failure (ALF). Liver injury tended to be more severe in those presenting after a booster (p=0.084). Pattern of liver injury was hepatocellular (80.9 %), mixed (12.8 %) and 3 (6.4 %) cholestatic. Liver biopsy was performed on 33 patients; 29 showed findings of AIH. Forty-one (87.2 %) patients received immunosuppressants, mostly corticosteroids (35/41). One required liver transplantation and another died due to ALF. Immunosuppression was discontinued in 6/41 patients without later rebound. Twenty-five subjects received at least one booster and 7 (28.0 %) relapsed from the liver injury, but all were non-severe. Recurrence was less frequent among patients on immunosuppressants at booster administration (28.6 % vs. 88.9 %, p=0.007). CONCLUSIONS: SARS CoV-2 vaccine-induced liver injury is heterogeneous but mostly immune-mediated. Relapse of liver injury after re-exposure to vaccine is frequent (28.0 %) but mild. Immunosuppression at booster administration is associated with a lower risk of liver injury.

RESUMO

BACKGROUND & AIMS: Information about the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients with liver cancer is lacking. This study characterizes the outcomes and mortality risk in this population. METHODS: Multicentre retrospective, cross-sectional, international study of liver cancer patients with SARS-CoV-2 infection registered between February and December 2020. Clinical data at SARS-CoV-2 diagnosis and outcomes were registered. RESULTS: Two hundred fifty patients from 38 centres were included, 218 with hepatocellular carcinoma (HCC) and 32 with intrahepatic cholangiocarcinoma (iCCA). The median age was 66.5 and 64.5 years, and 84.9% and 21.9% had cirrhosis in the HCC and iCCA cohorts respectively. Patients had advanced cancer stage at SARS-CoV-2 diagnosis in 39.0% of the HCC and 71.9% of the iCCA patients. After a median follow-up of 7.20 (IQR: 1.84-11.24) months, 100 (40%) patients have died, 48% of the deaths were SARS-CoV-2-related. Forty (18.4%) HCC patients died within 30-days. The death rate increase was significantly different according to the BCLC stage (6.10% [95% CI 2.24-12.74], 11.76% [95% CI 4.73-22.30], 20.69% [95% CI 11.35-31.96] and 34.52% [95% CI 17.03-52.78] for BCLC 0/A, B, C and D, respectively; p = .0017). The hazard ratio was 1.45 (95% CI 0.49-4.31; p = .5032) in BCLC-B versus 0/A, and 3.13 (95% CI 1.29-7.62; p = .0118) in BCLC-C versus 0/A in the competing risk Cox regression model. Nineteen out of 32 iCCA (59.4%) died, and 12 deaths were related to SARS-CoV-2 infection. CONCLUSIONS: This is the largest cohort of liver cancer patients infected with SARS-CoV-2. It characterizes the 30-day mortality risk of SARS-CoV-2 infected patients with HCC during this period.

RESUMO

BACKGROUND & AIMS: Hepatoblastoma (HB) is a rare disease. Nevertheless, it is the predominant pediatric liver cancer, with limited therapeutic options for patients with aggressive tumors. Herein, we aimed to uncover the mechanisms of HB pathobiology and to identify new biomarkers and therapeutic targets in a move towards precision medicine for patients with advanced HB. METHODS: We performed a comprehensive genomic, transcriptomic and epigenomic characterization of 159 clinically annotated samples from 113 patients with HB, using high-throughput technologies. RESULTS: We discovered a widespread epigenetic footprint of HB that includes hyperediting of the tumor suppressor BLCAP concomitant with a genome-wide dysregulation of RNA editing and the overexpression of mainly non-coding genes of the oncogenic 14q32 DLK1-DIO3 locus. By unsupervised analysis, we identified 2 epigenomic clusters (Epi-CA, Epi-CB) with distinct degrees of DNA hypomethylation and CpG island hypermethylation that are associated with the C1/C2/C2B transcriptomic subtypes. Based on these findings, we defined the first molecular risk stratification of HB (MRS-HB), which encompasses 3 main prognostic categories and improves the current clinical risk stratification approach. The MRS-3 category (28%), defined by strong 14q32 locus expression and Epi-CB methylation features, was characterized by CTNNB1 and NFE2L2 mutations, a progenitor-like phenotype and clinical aggressiveness. Finally, we identified choline kinase alpha as a promising therapeutic target for intermediate and high-risk HBs, as its inhibition in HB cell lines and patient-derived xenografts strongly abrogated tumor growth. CONCLUSIONS: These findings provide a detailed insight into the molecular features of HB and could be used to improve current clinical stratification approaches and to develop treatments for patients with HB. LAY SUMMARY: Hepatoblastoma is a rare childhood liver cancer that has been understudied. We have used cutting-edge technologies to expand our molecular knowledge of this cancer. Our biological findings can be used to improve clinical management and pave the way for the development of novel therapies for this cancer.

RESUMO

BACKGROUND & AIMS: Information on safety and efficacy of systemic treatment in patients with hepatocellular carcinoma (HCC) under dialysis are limited due to patient exclusion from clinical trials. Thus, we aimed to evaluate the rate, prevalence, tolerability, and outcome of sorafenib in this population. METHODS: We report a multicenter study comprising patients from Latin America and Europe. Patients treated with sorafenib were enrolled; demographics, dose modifications, adverse events (AEs), treatment duration, and outcome of patients undergoing dialysis were recorded. RESULTS: As of March 2018, 6156 HCC patients were treated in 44 centres and 22 patients were concomitantly under dialysis (0.36%). The median age was 65.5 years, 40.9% had hepatitis C, 75% had Child-Pugh A, and 85% were Barcelona Clinic Liver Cancer-C. The median time to first dose modification, treatment duration and overall survival rate were 2.4 months (interquartile ranges [IQR], 0.8-3.8), 10.8 months (IQR, 4.5-16.9), and 17.5 months (95% CI, 7.2-24.5), respectively. Seventeen patients required at least 1 dose modification. The main causes of first dose modification were asthenia/worsening of Eastern Cooperative Oncology Group-Performance Status and diarrhoea. At the time of death or last follow-up, four patients were still on treatment and 18 had discontinued sorafenib: 14 were due to tumour progression, 2 were sorafenib-related, and 2 were non-sorafenib-related AE. CONCLUSIONS: The outcomes observed in this cohort seem comparable to those in the non-dialysis population. Thus, to the best of our knowledge, this is the largest and most informative dataset regarding systemic treatment outcomes in HCC patients undergoing dialysis.

RESUMO

Mindfulness is defined as bringing one's attention to present-moment experience with acceptance, and is associated with engagement in various health behaviours. To synthesise and evaluate this literature, we conducted a comprehensive meta-analytic review and examined (a) the associations between trait mindfulness and health behaviours and (b) the extent to which these associations were moderated by study and individual differences. A total of 125 independent samples were included (N = 31,697, median male percentage = 38.8%, median age = 28.3). A multilevel random-effects model was used to estimate summary study-level effect sizes, and multilevel mixed-effects models were used to examine moderator effects. Mindfulness had a positive and small association with aggregated health behaviours (r = .08). Mindfulness was positively associated with physical activity, healthy eating, and sleep (rs = .08-.14), and negatively associated with alcohol use (r = -.06). Effects were larger for health promoting behaviours, the acting with awareness facet of mindfulness, and samples involving psychiatric patients. Although findings indicate that individual differences in trait mindfulness do not reliably translate into a pattern of healthful behaviours in general, trait mindfulness shows a stronger associations with health behaviours under certain conditions.

RESUMO

BACKGROUND: Chronic hepatic inflammation leads to liver fibrosis, which may progress to cirrhosis, a condition with high morbidity. Our aim was to assess the as yet unknown role of innate immunity protein CD5L in liver fibrosis. METHODS: CD5L was measured by ELISA in plasma samples from cirrhotic (n = 63) and hepatitis (n = 39) patients, and healthy controls (n = 7), by immunohistochemistry in cirrhotic tissue (n = 12), and by quantitative RT-PCR in mouse liver cell subsets isolated by cell sorting. Recombinant CD5L (rCD5L) was administered into a murine model of CCl4-induced fibrosis, and damage, fibrosis and hepatic immune cell infiltration, including the LyC6hi (pro-fibrotic)-LyC6low (pro-resolutive) monocyte ratio were determined. Moreover, rCD5L was added into primary human hepatic stellate cells to study transforming growth factor ß (TGFß) activation responses. FINDINGS: Cirrhotic patients showed elevated plasma CD5L concentrations as compared to patients with hepatitis and healthy controls (Mann-Whitney test p < 0·0001). Moreover, plasma CD5L correlated with disease progression, FIB4 fibrosis score (r:0·25, p < 0·0001) and tissue expression (r = 0·649; p = 0·022). Accordingly, CCl4-induced damage increased CD5L levels in total liver, particularly in hepatocytes and macrophages. rCD5L administration attenuated CCl4-induced injury and fibrosis as determined by reduced serum transaminase and collagen content. Moreover, rCD5L inhibited immune cell infiltration and promoted a phenotypic shift in monocytes from LyC6hi to LyC6low. Interestingly, rCD5L also had a direct effect on primary human hepatic stellate cells promoting SMAD7 expression, thus repressing TGFß signalling. INTERPRETATION: Our study identifies CD5L as a key pleiotropic inhibitor of chronic liver injury. FUND: Fundació Marató TV3, AGAUR and the ISCIII-EDRF.

RESUMO

BACKGROUND & AIMS: Despite direct-acting antivirals being highly effective at eradicating hepatitis C virus infection, their impact on the development of hepatocellular carcinoma (HCC) remains controversial. We analyzed the clinical and radiological outcome of cirrhotic patients treated with interferon-free regimens to estimate the risk of developing HCC. METHODS: This was a retrospective multicenter study focusing on cirrhotic patients treated with direct-acting antivirals until December 2016. Clinical and radiologic characteristics were collected before the start of antiviral therapy, at follow-up and at HCC development. Diagnosis of HCC was centrally validated and its incidence was expressed as HCC/100 person-years. RESULTS: A total of 1,123 patients were included (60.6% males, 83.8% Child-Pugh A) and 95.2% achieved a sustained virologic response. Median time of follow-up was 19.6 months. Seventy-two patients developed HCC within a median of 10.3 months after starting antiviral treatment. HCC incidence was 3.73 HCC/100 person-years (95% CI 2.96-4.70). Baseline liver function, alcohol intake and hepatic decompensation were associated with a higher risk of HCC. The relative risk was significantly increased in patients with non-characterized nodules at baseline 2.83 (95% CI 1.55-5.16) vs. absence of non-characterized nodules. When excluding these patients, the risk remained increased. CONCLUSION: These data expose a clear-cut time association between interferon-free treatment and HCC. The mechanisms involved in the increased risk of HCC emergence in the short term require further investigation. LAY SUMMARY: In this cohort of cirrhotic patients, interferon-free therapies achieved a high rate of sustained virologic response (>95%); however, we reported a risk of de novo hepatocellular carcinoma of 3.73 per 100 person-years and a clear-cut time association with antiviral therapy. The time association between starting direct-acting antivirals and developing hepatocellular carcinoma, together with the association with the presence of non-characterized nodules at baseline ultrasound, suggests that antiviral therapy elicits a mechanism (probably immune-related) that primes the growth and clinical recognition of hepatocellular carcinoma early during follow-up. As a result, short-term liver cancer risk is significantly increased.

RESUMO

Mindfulness-based treatments for eating disorders could be improved by understanding how facets of mindfulness predict eating disorder symptoms over time. We examined whether facets of mindfulness predict eating disorder symptoms over time and vice versa. Individuals with an eating disorder diagnosis (N = 124; 87.9% diagnosed with anorexia nervosa) and an undergraduate sample (N = 290) completed measures of mindfulness at baseline. The clinical sample also completed these measures 1 month later. Individuals in the clinical sample had lower acting with awareness and higher observing than individuals in the undergraduate sample (ps < 0.002). In the clinical sample, higher body dissatisfaction prospectively predicted lower acting with awareness (p = 0.02). Lower acting with awareness prospectively predicted higher drive for thinness (p < 0.01) and bulimic symptoms (p < 0.01). Acting with awareness shows potential as a process that can be altered to effect positive outcomes on drive for thinness and bulimic symptoms.

RESUMO

CD5-like (CD5L) is a soluble scavenger cysteine-rich protein that modulates inflammatory responses. We studied the involvement of CD5L in liver cancer. Immunohistochemistry (IHC) of CD5L in 60 hepatocellular carcinomas and 34 adjacent nontumor livers, showed that CD5L staining was higher in tumor than in nontumor tissue (Mann-Whitney test; P = 0.0039). High CD5L correlated with elevated proliferation (Ki67, linear regression; P < 0.0001) and lower patient event-free survival (log-rank; P = 0.0185). Accordingly, CD5L expression was detected in the liver cancer cell lines Huh7, HepG2, and SNU-398. In vitro technologies using these cell lines, including small interfering RNA (siRNA) and cDNA transfection, showed that CD5L promoted colony formation and cell proliferation and protected against cisplatin-induced apoptosis. To find a molecular explanation for these roles, novel CD5L-interacting protein ligands in liver cancer cells were identified by immunoprecipitation followed by mass spectrometry. Among these, the molecular chaperone of the unfolded protein response (UPR), heat shock protein (HSP)-A5, was selected for validation. The interaction was confirmed by confocal microscopy in the Huh7 and HepG2 cell lines. Furthermore, functional experiments revealed that CD5L activates the UPR and autophagy mechanisms in Huh7 cells, thereby providing a novel molecular link between the UPR and autophagy in liver cancer.-Aran, G., Sanjurjo, L., Bárcena, C., Simon-Coma, M., Téllez, É., Vázquez-Vitali, M., Garrido, M., Guerra, L., Díaz, E., Ojanguren, I., Elortza, F., Planas, R., Sala, M., Armengol, C., Sarrias, M.-R. CD5L is upregulated in hepatocellular carcinoma and promotes liver cancer cell proliferation and antiapoptotic responses by binding to HSPA5 (GRP78).

RESUMO

The clinical benefit of sorafenib in patients with hepatocellular carcinoma (HCC) has been undervalued due to the absence of complete responses, even though patients who develop early dermatologic reactions have shown to have a positive outcome. In addition, sorafenib is described as an antiangiogenic drug, but it also acts on immunological cells. Thus, the goal of this study was to assess the complete response rate in a retrospective cohort of HCC patients treated with sorafenib and to describe the profile of the patients who achieve complete response for identifying factors related to this event and their connection with the immunological profile of sorafenib. Ten Spanish centers submitted cases of complete response under sorafenib. The baseline characteristics, development of early dermatologic reactions, and cause of treatment discontinuation were annotated. Radiological images taken before starting sorafenib, at first control, after starting sorafenib, at the time of complete response, and at least 1 month after treatment were centrally reviewed. Of the 1119 patients studied, 20 had been classified as complete responders by the centers, but eight of these patients were excluded after central review. Ten patients had complete disappearance of all tumor sites, and two had just a small residual fibrotic scar. Thus, 12 patients were classified as complete responders (58% HCV, median age 59.7 years, 83.4% Child-Pugh class A, Eastern Cooperative Oncology Group performance status 0 91.7%, and Barcelona Clinic Liver Cancer stage C 83.3%). The median overall survival and treatment duration were 85.8 and 40.1 months, respectively. All but one patient developed early dermatologic reactions, and seven patients discontinued sorafenib after achieving complete response due to adverse events, patient decision, or liver decompensation. Conclusion: Complete response affects 1% of patients with HCC who are treated with sorafenib. The association of complete response with early dermatologic reactions supports the role of a specific immune/inflammatory patient profile in the improved response to sorafenib.

RESUMO

Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide with over 740,000 new cases per year and the third leading cause of cancer-related death, with a growing incidence in recent years. This tumor usually arises in patients with an underlying chronic liver disease. The management of this tumor has improved over the past 2 decades: patients at risk are included in a surveillance program, a prognostic staging system has been created and, finally, new treatments particularly aimed at patients with advanced HCC have been developed. This fact has resulted in a greater interest in this tumor and several scientific societies have developed clinical practice guidelines for the management of patients with this disease. In this article, we review the current and future prospects of this tumor.

RESUMO

BACKGROUND: Roux-en-Y gastric bypass (RYGB) accelerates gastric pouch emptying, enhances postprandial glucagon-like peptide 1 (GLP-1) and insulin, and lowers glucose concentrations. To prevent discomfort and reactive hypoglycemia, it is recommended that post-RYGB patients eat small, frequent meals and avoid caloric drinks. However, the effect of meal size and texture on GLP-1 and metabolic response has not been studied. OBJECTIVES: To demonstrate that frequent minimeals and solid meals (S) elicit less GLP-1 and insulin release and less reactive hypoglycemia and are better tolerated compared with a single isocaloric liquid meal (L). SETTING: A university hospital. METHODS: In this prospective study, 32 RYGB candidates were enrolled and randomized to L or S groups before gastric bypass. Each subject received an L or S 600-kcal single meal (SM) administered at hour 0 or three 200-kcal minimeals administered at hours 0, 2, and 4 on 2 separate days. Twenty-one patients were retested 1 year after RYGB. Blood and visual analogue scale measurements were collected up to 6 hours postprandially. Outcome measures included gastric pouch emptying, glucose, insulin, and GLP-1; hunger, fullness, and stomach discomfort were measured by visual analogue scale. RESULTS: Twenty-one were patients retested after RYGB (L: n = 12; S: n = 9). Meal texture had a significant effect on peak GLP-1 (L-SM: 106.1 ± 67.2 versus S-SM: 45.3 ± 25.2 pM, P = .004), peak insulin, and postprandial glucose. Hypoglycemia was more frequent after the L-SM meal compared with the S-SM. Gastric pouch emptying was 2.4 times faster after RYGB but was not affected by texture. CONCLUSIONS: Meal texture and size have significant impact on tolerance and metabolic response after RYGB.

RESUMO

BACKGROUND AND OBJECTIVE: In 2010 we published that 53% of cases of hepatocellular carcinoma (HCC) detected in Spain were diagnosed outside the context of standard screening programs, which consequently leads to lower survival rates. The aim of this study was to analyze the current situation and the causes of diagnosis out of screening programs. MATERIAL AND METHODS: Prospective registry of 73 second- and third-level Spanish healthcare centers carried out between October 1, 2014 and January 31, 2015. The baseline characteristics of the disease and the first treatment administered for the incidental primary liver tumors during such period were recorded. RESULTS: A total of 720 patients were included in the study: HCC (n=686), intrahepatic cholangiocarcinoma (n=29), hepatic cholangiocarcinoma (n=2), other (n=3). HCC characteristics: male 82%; mean age 67 years; cirrhosis 87%; main etiologies: alcohol 35%, HCV 30%, alcohol and HCV 15%, non-alcoholic fatty liver disease 6%; tumor stage: BCLC-0 11%, A 43%, B 19%, C 16% and D 11%; first treatment: transarterial chemoembolization (23%), percutaneous ablation (22%), symptomatic treatment (20%), resection (11%), sorafenib (11%). Three hundred and fifty-six patients (53%) were diagnosed outside of screening programs, mainly owing to the fact that they suffered from an undiagnosed liver disease (76%) and to the poor adherence to the screening program (18%). These patients were mainly male (P<.001), with an alcoholic etiology (P<.001) and active alcohol consumption (P<.001). Moreover, the disease was predominantly diagnosed at more advanced stages (P<.001) and was addressed with less radical treatments (P<.001). CONCLUSIONS: In Spain, the main cause of diagnosis of a HCC outside the context of a screening program is the absence of a prior diagnosis of a liver disease, particularly in alcohol-consuming men. Detecting a liver disease in asymptomatic populations and improving adherence to screening programs are the main areas that must be subject to improvement in order to improve the early detection of HCC.

RESUMO

OBJECTIVE: Self-persuasion is an effective behavior change strategy, but has not been translated for low-income, less educated, uninsured populations attending safety-net clinics or to promote human papillomavirus (HPV) vaccination. We developed a tablet-based application (in English and Spanish) to elicit parental self-persuasion for adolescent HPV vaccination and evaluated its feasibility in a safety-net population. METHODS: Parents (N=45) of age-eligible adolescents used the self-persuasion application. Then, during cognitive interviews, staff gathered quantitative and qualitative feedback on the self-persuasion tasks including parental decision stage. RESULTS: The self-persuasion tasks were rated as easy to complete and helpful. We identified six question prompts rated as uniformly helpful, not difficult to answer, and generated non-redundant responses from participants. Among the 33 parents with unvaccinated adolescents, 27 (81.8%) reported deciding to get their adolescent vaccinated after completing the self-persuasion tasks. CONCLUSIONS: The self-persuasion application was feasible and resulted in a change in parents' decision stage. Future studies can now test the efficacy of the tablet-based application on HPV vaccination. PRACTICE IMPLICATIONS: The self-persuasion application facilitates verbalization of reasons for HPV vaccination in low literacy, safety-net settings. This self-administered application has the potential to be more easily incorporated into clinical practice than other patient education approaches.

RESUMO

Abstract: The aim of this study was to develop fotonovelas , a popular type of graphic novel in the Latino population, to raise awareness and educate about eating disorders (EDs). Four illustrated cartoons and scripts tailored for adults and adolescents of both sexes were presented in focus groups and an in-depth interview. Seventeen Latino adults (14 females; 3 males) and 10 adolescents (9 females; 1 male) participated in the study. Participants found the fotonovelas interesting, and eye-catching than traditional brochures. The use of Spanglish and clarification of differences across EDs were suggested by adolescent females. Male adults suggested changing the title to focus on the health consequences of EDs in order to catch the male attention in reading the story. Based on the receptivity we found in this study, fotonovela could be a promising avenue to raise awareness and to educate the Latino community in the United States about EDs.


Resumen: El objetivo de este estudio fue desarrollar fotonovelas, un tipo de novela gráfica popular en la población latina, para crear conciencia y educar sobre los trastornos de la conducta alimentaria (TCA). Cuatro caricaturas ilustradas y guiones adaptados para adultos y adolescentes de ambos sexos fueron presentados en discusiones focales y en una entrevista de profundidad. Diecisiete latinos adultos (14 mujeres; 3 hombres) y 10 adolescentes (9 féminas; 1 varón) participaron en el estudio. Los participantes encontraron las fotonovelas interesantes y que captaban más la atención que los folletos tradicionales. El uso del espanglish y la clarificación de las diferencias entre los TCA fueron sugeridos por las adolescentes femeninas. Los adultos varones sugirieron cambiar el título, que se enfocara en las consecuencias en la salud de los TCA para que llame la atención en los hombres a leer la historia. Basado en la aceptación encontrada en este estudio, la fotonovela pudiera ser una avenida prometedora para crear conciencia y educar a la comunidad latina sobre los TCA en los Estados Unidos.

RESUMO

INTRODUCTION: GIDEON is a non-interventional, prospective, international study that evaluated the safety of sorafenib in patients with unresectable hepatocellular carcinoma (HCC) in daily clinical practice, including Child-Pugh B patients. OBJECTIVES: To analyze data collected in Spain on the safety and efficacy of sorafenib and treatment patterns. METHODS: Data were collected during follow-up on demographic and disease characteristics, the initial dose used, treatment-emergent adverse events (AEs) and dose modifications. Overall survival was evaluated, as well as time to disease progression. Efficacy and safety were analyzed according to the Child-Pugh classification and the initial dose. RESULTS: We included 143 patients from 19 Spanish hospitals. A total of 24.5% of the patients were Child-Pugh B. An initial dose of 400 mg/12 h was used in 90.9% of patients. In Child-Pugh A patients, dose modifications occurred more frequently and the treatment duration was longer. The incidence of AEs and drug-related AEs were similar in Child-Pugh A and B patients, although serious AEs were more frequent in Child-Pugh B patients. The most common AEs were diarrhea, fatigue and hand-foot skin reactions. The median overall survival was 384 days and was higher in Child-Pugh A patients (593 vs. 211 days in Child-Pugh B). The median time to disease progression was 177 days, similar in both subgroups. CONCLUSION: The safety profile of sorafenib in Spanish patients with unresectable HCC is independent of liver function. Child-Pugh status does not seem to influence the approach to sorafenib dosage or time to progression but does seem to be a strong prognostic factor for survival.
