ABSTRACT: Background
Hepatocellular carcinoma (HCC) may arise from genomic instability and has dismal outcome. Sorafenib is the first-line treatment for advanced stage HCC, but its therapeutic efficacy is less than 50%. Biomarkers for predicting the therapeutic efficacy of sorafenib administration to patients with advanced HCC are required. Here, we evaluated the role of chromosomal copy number aberrations (CNAs) in patients with advanced HCC who were treated with sorafenib along with their drug response.Methods
The response to sorafenib treatment of twenty-three HCC patients who developed advanced recurrence after partial hepatectomy was analyzed using the modified Response Evaluation Criteria in Solid Tumors (mRECIST). Formalin fixed paraffin embedded (FFPE) tissue specimens obtained after tumor resection were analyzed using the Affymetrix OncoScan® FFPE assay.Results
From the 23 patients analyzed in this study, 7 (30.4%) had complete/partial response to sorafenib (CR/PR), 7 (30.4%) had stable disease (SD), and 9 (39.1%) had progressive disease (PD). The mean genome-wide percentage of genome change acquisition via the OncoScan platform was 19.8% for patients with CR/PR/SD and 50.02% in the PD group (p = 0.055). Percentage of genome change above 33% was associated with adverse outcomes for sorafenib treatment in the time-to-progression analysis (p = 0.007) and overall survival (p = 0.096). Among these CNAs, amplification of chromosome 7q, containing the multidrug resistance gene ATP Binding Cassette Subfamily B Member 1 (ACBC1), significantly associated with poor overall survival (p = 0.004) and time-to-progression (p < 0.001).Conclusions
Higher percentage genome change and amplification of chromosome 7q in advanced HCC is associated with sorafenib resistance.

Project description:BackgroundPhase III trials show sorafenib improves survival in advanced hepatocellular carcinoma (HCC). Because of narrow trial eligibility, results may not be generalizable to a broader HCC population. We sought to evaluate the effectiveness of initial sorafenib versus no treatment among Medicare beneficiaries with advanced HCC.Materials and methodsPatients with advanced HCC diagnosed from 2008 to 2011 were identified from the Surveillance, Epidemiology, and End Results-Medicare database. Eligible patients received initial sorafenib or no therapy and were covered by Medicare parts A, B, and D. Sorafenib use and outcomes were described in this population. Using a propensity score (PS)-matched sample, we compared the effectiveness of sorafenib versus no treatment by Cox proportional hazards and binomial regression, using a landmark requiring all patients to survive ?60 days after diagnosis.ResultsOf 1,532 patients, 27% received initial sorafenib. Median duration of sorafenib use was 60 days (interquartile range [IQR], 30-107 days), and median survival from first prescription was 3 months (IQR, 1-8 months). In the PS-matched cohort, median survival was 3 months from the 60-day landmark in sorafenib-treated (n = 223) and 2 months in untreated (n = 223) patients (adjusted hazard ratio, 0.95 [95% confidence interval (CI), 0.78-1.16]). Sorafenib was associated with a nonsignificant reduction in mortality at 3 months (44% versus 51%; adjusted risk ratio, 0.88 [95% CI, 0.72-1.07]), but no reduction thereafter.ConclusionSurvival after sorafenib initiation in newly diagnosed Medicare beneficiaries with HCC is exceptionally short, suggesting trial results are not generalizable to all HCC patients. The downsides of sorafenib use-high drug-related symptom burden and high drug cost-must be considered in light of this minimal benefit.Implications for practiceThe findings of a median survival of only 3 months in Medicare beneficiaries with HCC prescribed sorafenib as first-line therapy highlight the questionable value of sorafenib in this population. Patients should be cautioned that outside of the narrow confines of randomized trials, their life expectancy may be very short, and any benefit of sorafenib is likely to be quite small. Given that sorafenib causes considerable adverse effects and offers no symptom palliation, supportive care should be discussed as a reasonable alternative to sorafenib, particularly for patients who have a poor performance status or advanced cirrhosis.

Project description:BACKGROUND AND AIMS:The present study aims to investigate the role of the prognostic nutritional index (PNI) on survival in patients with advanced hepatocellular carcinoma (HCC) treated with sorafenib. METHODS:This multicentric study included a training cohort of 194 HCC patients and three external validation cohorts of 129, 76 and 265 HCC patients treated with Sorafenib, respectively. The PNI was calculated as follows: 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (per mm3). Univariate and multivariate analyses were performed to investigate the association between the covariates and the overall survival (OS). RESULTS:A PNI cut-off value of 31.3 was established using the ROC analysis. In the training cohort, the median OS was 14.8 months (95% CI 12-76.3) and 6.8 months (95% CI 2.7-24.6) for patients with a high (>31.3) and low (<31.3) PNI, respectively. At both the univariate and the multivariate analysis, low PNI value (p = 0.0004), a 1-unit increase of aspartate aminotransferase (p = 0.0001), and age > 70 years (p< 0.0038) were independent prognostic factors for OS. By performing the same multivariate analysis of the training cohort, the PNI <31.3 versus >31.3 was found to be an independent prognostic factor for predicting OS in all the three validation cohorts. CONCLUSIONS:PNI represents a prognostic tool in advanced HCC treated with first-line Sorafenib. It is readily available and low-cost, and it could be implemented in clinical practice in patients with HCC.

Project description:The kinase inhibitor sorafenib is the only systemic therapy proven to have a positive effect on survival of patients with advanced hepatocellular carcinoma (HCC). After development of sorafenib and its introduction as a therapeutic agent used in the clinic, several critical questions have been raised. Clinical parameters and biomarkers predicting sorafenib efficacy are the most important issues that need to be elucidated. Although it is difficult to know the responders in advance using conventional characteristics of patients, there are specific serum cytokines and/or gene amplification in tumor tissues that have been reported to predict efficacy of sorafenib. Risk and benefits of continuation of sorafenib beyond radiological progression is another issue to consider because no other standard therapy for advanced HCC as yet exists. In addition, effectiveness of the expanded application of sorafenib is still controversial, although a few studies have shed some light on combinational treatment with sorafenib for intermediate-stage HCC. Recently, over 50 relevant drugs have been developed and are currently under investigation. The efficacy of some of these drugs has been extensively examined, but none have demonstrated any superiority over sorafenib, so far. However, there are several drugs that have shown efficacy for treatment after sorafenib failure, and these are proceeding to further studies. To address these issues and questions, we have done extensive literature review and summarize the most current status of therapeutic application of sorafenib.

Project description:BackgroundAlthough sorafenib is accepted as the standard of care in advanced hepatocellular carcinoma (HCC), its therapeutic benefit is marginal. Here, we aimed to compare the efficacy and safety of sorafenib monotherapy (S-M) and sorafenib-based loco-regional treatments (S-LRTs) in advanced HCC.MethodsFrom 2007 to 2012, 290 patients with advanced HCC (Barcelona Clinic Liver Cancer stage C) with S-M (n = 226) or S-LRTs (n = 64) were reviewed retrospectively. Survival outcomes and treatment-related toxicities between two groups were analyzed.ResultsVariables related to tumor burden and liver function were similar between the groups (all P > 0.05). Within the entire population, the S-LRTs group had both longer median overall survival (OS) (8.5 vs 5.5 months, P = 0.001) and progression-free survival (PFS) (5.3 vs 3.0 months, P = 0.002) than the S-M group. Furthermore, the S-LRTs group had longer Os than the S-M group in a subgroup with neither extrahepatic spread (EHS) nor regional nodal involvement (RNI) (18.0 vs 7.8 months, P = 0.019) and in a subgroup with EHS and/or RNI (8.3 vs 4.8 months, P = 0.028). In addition, the S-LRTs group had longer PFS than the S-M group in the subgroup with neither EHS nor RNI (9.6 vs 3.2 months, P = 0.027).TreatmentRelated toxicity was similar between two groups.ConclusionCombined use of sorafenib and LRTs may provide better treatment outcomes without significantly increasing treatment-related toxicities, even in patients with EHS and/or RNI. Therefore, addition of active LRTs might be considered, if feasible.

Project description:Sorafenib is a multiple receptor tyrosine kinase inhibitor known to prolong overall survival in patients with advanced hepatocellular carcinoma (HCC). Predicting this drug's survival benefits is challenging because clinical responses are rarely measurable during treatment. In this study, we hypothesized that serum cytokines levels could predict the survival of advanced HCC patients, as sorafenib targets signaling pathways activated in the tumor stromal microenvironment and potentially affects serum cytokine profiles.Of 143 patients with advanced-stage HCC, 104 who were recruited between 2003 and 2007 received hepatic arterial infusion chemotherapy (HAIC) that mainly targets tumor epithelial cells at S-phase (cohort 1); additionally, 39 recruited between 2010 and 2012 received sorafenib, which primarily targets the stromal vascular endothelial cells. Serum samples were collected and aliquoted prior to the treatment. Serum EGF, bFGF, HGF, IFN-?, IL-10, IL-12, IL-2, IL-4, IL-5, IL-6, IL-8, IP-10, MIG, PDGF-BB, SCF, SDF1, TGF-?, TGF-?, TNF-?, and VEGF-A were measured via enzyme-linked immunosorbent assays. The Modified Response Evaluation Criteria in Solid Tumors were used to assess tumor responses.The median survival time of HCC patients in cohorts 1 (HAIC-treated) and 2 (sorafenib-treated) were 12.0 and 12.4 months, respectively. Kaplan-Meier analysis revealed no significant survival differences between the 2 groups. Patients who survived more than 2 years after sorafenib treatment exhibited higher serum levels of IL-10, IL-12, TNF-a, IL-8, SDF-1, EGF, PDGF-BB, SCF, and TGF-?. Furthermore, cohort 2 patients with higher serum IL-5 (>12 pg/mL), IL-8 (>10 pg/mL), PDGF-BB (>300 pg/mL), and VEGF-A (>50 pg/mL) levels achieved longer survival; cohort 1 patients did not. Hierarchical cluster analysis of 6 cytokines robustly enriched for comparison analysis between cohorts 1 and 2 (IL-5, IL-8, TGF-?, PDGF-BB, CXCL9, and VEGF-A) revealed that elevation of these cytokines correlated with better survival when treated with sorafenib but not with HAIC.Patients who exhibited survival benefits owing to sorafenib treatment tended to present higher serum cytokines levels, potentially reflecting the activation of stromal signaling in the tumor microenvironment. Our study thus introduces novel biomarkers that may identify advanced HCC patients who may experience survival benefits with sorafenib treatment.

Project description:Sorafenib is an effective systemic agent for advanced hepatocellular carcinoma. To increase its efficacy, we evaluated the feasibility and benefit of sorafenib combined with radiotherapy.From July 2007 to July 2011, 31 patients were treated with a daily dose of 800 mg of sorafenib and radiotherapy. Among them, 13 patients who received radiotherapy on the bone metastasis were excluded. Thirteen patients received 30-54 Gy of radiotherapy on the primary tumor (primary group) and 5 patients received 30-58.4 Gy on the measurable metastatic lesions (measurable metastasis group). Tumor responses at 1 month after the completion of radiotherapy and overall survival were evaluated.The in-field response rate was 100% in the primary group and 60% in the measurable metastasis group. A decrease of more than 80% in the tumor marker ?-fetoprotein was observed in 7 patients in the primary group (54%). Toxicities of grades 3-4 were hand-foot syndrome in 3 (17%) patients, duodenal bleeding in 1 (6%) patient, thrombocytopenia in 3 (17%) patients and elevation of aspartate transaminase in 1 (6%) patient. The median overall survival was 7.8 months (95% confidence interval, 3.0-12.6).The combined treatment of sorafenib and radiotherapy was feasible and induced substantial tumor responses in the target lesions. The results of this study emphasize the importance of individualized approach in the management of advanced hepatocellular carcinoma and encourage the initiation of a controlled clinical trial.

Project description:Targeted therapy is currently the standard treatment for advanced hepatocellular carcinoma (HCC), but an effective treatment after the discontinuation of sorafenib therapy remains uncertain. We aim to investigate the survival benefits of transcatheter arterial chemoembolization (TACE) after stopping sorafenib therapy. We retrospectively analyzed all patients with advanced HCC, who had received palliative TACE after terminating sorafenib therapy, from January 2008 to June 2016. Patients who were in the terminal stage (Child-Pugh class C or performance status 3-4), who received a liver transplantation, or who had received any HCC treatment other than TACE, were excluded. Finally, 28 patients were recruited as the TACE group, and were randomly matched 1:1 by age, gender, Child-Pugh class, extrahepatic metastasis, and portal vein thrombosis with 28 controls who only received supportive care. For avoiding any immortal time bias, the index date of outcome follow-up was also matched. Cumulative incidences of, and hazard ratios (HRs) for, patient mortality were analyzed. The baseline demographic data between the TACE group and the control group were similar, but the 1-year overall survival rate in the TACE group was significantly higher than that of the control group (41.2%, 95% confidence interval [CI]: 19.4-63.0% vs. 24.5%, 95% CI: 6.3-42.7%; p < 0.01). In multivariate analysis, after adjusting for alpha-fetoprotein > 400ng/mL, Child-Pugh class B, and tumor extension > 50% of liver volume, TACE was independently associated with a decreased mortality risk(HR 0.19, 95% CI: 0.08-0.42). In addition, tumor extension > 50% of the liver was another independent prognostic factor associated with an increased mortality risk (HR 2.99, 95% CI: 1.31-6.82). Multivariate stratified analyses verified the association of TACE with a decreased mortality rate in each patient subgroup (all HR < 1.0). By controlling intrahepatic tumor growth, TACE may be a treatment option for use in improving patient survival in advanced HCC, after the termination of sorafenib therapy.

Project description:BackgroundMajority of patients of hepatocellular carcinoma (HCC) in India present in advanced stages, when curative treatment options are limited. We undertook this study to assess the cost-effectiveness of treating advanced HCC patients with sorafenib compared with best supportive care (BSC).MethodsA Markov model was parameterized to model the lifetime costs and consequences of treating advanced HCC patients with sorafenib versus BSC using a societal perspective. Cost of routine care, diagnostics, management of complications in both the arms and management of adverse effects of sorafenib treatment were considered. A probabilistic sensitivity analysis was undertaken to assess the effect of parameter uncertainty.ResultsThe incremental cost and benefit gained by treating HCC using sorafenib was Indian rupees 94,182 ($1459) and 0.19 quality adjusted life years (QALYs) per patient, implying an incremental cost of Indian rupees 507,520 ($7861) per QALY gained.ConclusionsSorafenib is not cost-effective for use in advanced hepatocellular carcinoma treatment in India.

Project description:Sorafenib is the first and only p.o. administrated drug currently approved to treat advanced hepatocellular carcinoma (HCC). However, concerns have been raised about sorafenib therapy, including acquired drug resistance. This review provides an overview of sorafenib in the treatment of HCC on the basis of data obtained in the laboratory and in clinical studies. Three underlying mechanisms have been found to support sorafenib therapy. First, sorafenib blocks HCC cell proliferation by inhibiting BRaf and Raf1/c-Raf serine/threonine kinase phosphorylation in the mitogen-activated protein kinase pathway. Second, sorafenib induces apoptosis by reducing elF4E phosphorylation and downregulating Mcl-1 levels in tumor cells. Third, sorafenib prevents tumor-associated angiogenesis by inactivating vascular endothelial growth factor receptors (VEGFR-2 and -3) and the platelet-derived growth factor receptor-β. Clinical trials have demonstrated the effectiveness and relative safety of sorafenib, and thus the drug is used in unresectable HCC. However, many patients may develop acquired resistance to sorafenib, so their response to sorafenib is eventually lost. Sorafenib may induce autophagy, which leads to apoptosis. However, autophagy can also cause drug resistance. Many studies have combined sorafenib with other treatments in an effort to increase its effects, reduce the necessary dose or overcome resistance. It is urgent to study the mechanisms underlying how sorafenib interacts with cellular molecules and other drugs to increase its efficacy and reduce resistance in HCC patients.

Project description:BackgroundApatinib, a selective inhibitor of vascular endothelial growth factor receptor 2 (VEGFR 2), has exhibited modest antitumor efficacy in hepatocellular carcinoma (HCC). We aimed to evaluate the effectiveness and tolerability of apatinib versus sorafenib in patients with advanced HCC.MethodsAll patients with advanced HCC who underwent sorafenib or apatinib between January 2016 to December 2017 were retrospectively reviewed. Seventy-two patients received apatinib (26 patients, 500 mg, daily) or sorafenib (46 patients, 400 mg, twice daily) until disease progression or intolerable toxicities. Primary outcome was progression-free survival (PFS). Secondary outcomes included overall survival (OS), objective response rate (ORR) per modified response evaluation criteria in solid tumors (RECIST), disease control rate (DCR), and safety.ResultsThe median follow-up was 13.2 (5.7-20.7) months. The 1-year OS for apatinib of 62.0% was comparable to that of sorafenib [64.2%, hazard ratio (HR), 1.15; 95% confidence interval (CI), 0.369-3.58]. The median PFS was 4.1 months in the apatinib group (95% CI, 3.2 to 7.4 months) and 3.6 months in the sorafenib group (95% CI, 2.7 to 5.9 months; HR, 1.03; 95% CI, 0.586 to 1.800; P=0.925). The apatinib group exhibited higher ORR (19.2% vs. 2.2%, P=0.012) but similar DCR (57.7% vs. 50%, P=0.530) compared with the sorafenib group. The most common any-grade adverse events in the apatinib and sorafenib groups were hand and foot syndrome (53.8% vs. 50%), hypertension (50% vs. 19.6%), diarrhea (34.6% vs. 28.3%), and elevated transaminase (57.7% vs. 63%).ConclusionsCompared with sorafenib, apatinib yielded comparable PFS and OS, and even better ORR, in patients with advanced HCC.
