AIM:To investigate the clinical course of untreatable hepatocellular carcinoma (HCC) identified at any stage and to identify factors associated with mortality.
The prevalence of hepatocellular carcinoma in Europe and the US is increasing and is currently the leading cause of death in patients with cirrhosis. Surveillance programs for patients with cirrhosis aim to detect tumors at an early stage, when the greatest therapeutic benefits can be achieved. Curative treatments for early-stage tumors include liver transplantation, resection and percutaneous ablation. Transarterial chemoembolization (TACE) and sorafenib can improve survival for patients with intermediate and advanced tumors, respectively. In clinical practice, combination therapies are often used, despite limited evidence to support this approach from randomized controlled trials. Combination therapy with radiofrequency ablation (RFA) plus percutaneous ethanol injection can, however, improve survival for selected patients compared with RFA alone. Combined treatment with TACE and RFA also improves patients' survival compared with TACE or RFA monotherapy. TACE performed before or after surgical resection, however, is not beneficial. Prevention of tumor progression in patients awaiting liver transplantation requires nonsurgical treatments; however, the real advantages of the available treatment modalities are yet to be defined. The role of sorafenib administration in combination with TACE after the use of potentially curative treatments, for the treatment of intermediate hepatocellular carcinoma, or in selective settings after liver transplantation, requires further study.
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 group of patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
