Response to transarterial chemoembolization as a biological selection criterion for liver transplantation in hepatocellular carcinoma.

2006

Criteria to select patients with hepatocellular carcinoma (HCC) for liver transplantation (LT) are based on tumor size and number of nodules rather than on tumor biology. The present study was undertaken to assess the role of transarterial chemoembolization (TACE) in selecting patients with tumors suitable for LT. Ninety-six consecutive patients with HCC were treated by repeatedly performed TACE, 62 of them exceeding the Milan criteria. Patients meeting the Milan criteria were immediately listed, and patients beyond the listing criteria were listed upon downstaging of the tumor following successful TACE. Fifty patients were finally transplanted. Of these 50 patients, 34 exceeded the Milan c…

The impact of portal vein tumor thrombosis on survival in patients with hepatocellular carcinoma treated with different therapies: A cohort study.

2020

Background Portal vein tumor thrombosis (PVTT) is a frequent complication of hepatocellular carcinoma (HCC), which leads to classification as advanced stage disease (regardless of the degree of PVTT) according to the Barcelona Clinic Liver Cancer Classification. For such patients, systemic therapy is the standard of care. However, in clinical reality, many patients with PVTT undergo different treatments, such as resection, transarterial chemoembolization (TACE), selective internal radiation therapy (SIRT), or best supportive care (BSC). Here we examined whether patients benefited from such alternative therapies, according to the extent of PVTT. Methods This analysis included therapy-naïve …

Chemoembolization for hepatocellular carcinoma : optimization of the procedure

2011

With 700,000 deaths in 2008, hepatocellular carcinoma is the 3rd most common cause of cancer-related death worldwide. Transarterial chemoembolization is the standard treatment for intermediate-stage hepatocellular carcinoma. This intraarterial treatment is performed by injecting an anticancer drug carried by ethiodized oil or by drug-eluting beads and followed by the occlusion of the artery when ethiodized oil is used. Median survival of patients remains < 2 years, and there is no consensus about the optimal treatment regimen. The aim of our work was to improve the efficacy of transarterial chemoembolization in optimizing the anticancer drug and its carrier.We have demonstrated that idarubi…

Transarterial chemoembolization and sorafenib in hepatocellular carcinoma

2014

Transarterial chemoembolization (TACE) is considered as the standard therapy for patients with intermediate-stage hepatocellular carcinoma. However, given the high heterogeneity of this population, no common strategy or protocol standardization has been defined yet. In the last few years TACE treatment has been combined with sorafenib systemic therapy, reporting overall positive results both in terms of safety and efficacy. This systematic review presents and critically discusses the evidence available on the use of TACE in combination (concomitant or sequential) with sorafenib, focusing also on clinical trials currently ongoing to better define an optimal therapeutic strategy for this grou…

Heterogeneity of Patients with Intermediate (BCLC B) Hepatocellular Carcinoma: Proposal for a Subclassification to Facilitate Treatment Decisions

2013

The intermediate stage of hepatocellular carcinoma (HCC) comprises a highly heterogeneous patient population and therefore poses unique challenges for therapeutic management, different from the early and advanced stages. Patients classified as having intermediate HCC by the Barcelona Clinic Liver Cancer (BCLC) staging system present with varying tumor burden and liver function. Transarterial chemoembolization (TACE) is currently recommended as the standard of care in this setting, but there is considerable variation in the clinical benefit patients derive from this treatment.In April 2012, a panel of experts convened to discuss unresolved issues surrounding the application of current guidel…

Volumetric Enhancing Tumor Burden at CT to Predict Survival Outcomes in Patients with Neuroendocrine Liver Metastases after Intra-arterial Treatment

2023

Purpose To investigate whether liver enhancing tumor burden (LETB) assessed at contrast-enhanced CT indicates early response and helps predict survival outcomes in patients with multifocal neuroendocrine liver metastases (NELM) after intra-arterial treatment. Materials and Methods This retrospective study included patients with NELM who underwent intra-arterial treatment with transarterial embolization (TAE) or chemoembolization (TACE) between April 2006 and December 2018. Tumor response in treated NELM was evaluated by using the Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST (mRECIST). LETB was measured as attenuation 2 SDs greater than that of a region of intere…

Multidisciplinary strategies to improve treatment outcomes in hepatocellular carcinoma

2013

Hepatocellular carcinoma (HCC) is a complex disease with a poor prognosis. Incidence and mortality rates are increasing in many geographical regions, indicating a need for better management strategies. Among several risk factors for HCC, the most common are cirrhosis because of chronic hepatitis B virus or hepatitis C virus infection and alcohol consumption, obesity, and diabetes. In some patients, combined risk factors present additional challenges to the prevention and treatment of HCC. Screening and surveillance of high-risk populations varies widely by geographic regions, and access to optimal surveillance is critical for early diagnosis. The treatment choice for HCC depends on the canc…

TACE versus TAE as therapy for hepatocellular carcinoma

2008

Transarterial chemoembolization (TACE) improves survival in cirrhotic patients with hepatocellular carcinoma (HCC). The optimal schedule, best anticancer agent and best technique are still unclear. TACE may not be better than transarterial embolization (TAE). HCC is very chemoresistant, thus embolization may be more important than chemotherapy. Lipiodol cannot be considered as an embolic agent and there are no data to show that it can release chemotherapeutic agents slowly. It can mask residual vascularity on CT imaging and its use is not recommended. Both TACE and TAE result in hypoxia, which stimulates angiogenesis, promoting tumor growth; thus combination of TACE with antiangiogenic agen…

Are radiological endpoints surrogate outcomes of overall survival in hepatocellular carcinoma treated with transarterial chemoembolization?

2021

Background&amp; Aims: Time to progression (TTP) and progression-free survival (PFS) are commonly used as surrogate endpoints in oncology trials. We aimed to assess the surrogacy relationship of TTP and PFS with overall survival (OS) in studies of transarterial chemoembolization (TACE) for unresectable hepatocellular carcinoma (u-HCC) by innovative methods. Methods: A search of databases for studies of TACE for u-HCC reporting both OS and TTP or PFS was performed. Individual patient data were extracted from TTP/PFS and OS Kaplan-Meier curves of TACE arms. Pooled median TTP and OS were obtained from random-effect model. The surrogate relationships of hazard ratios (HRs) and median TTP for OS …
