Project description:Primary liver cancer, mainly consisting of hepatocellular carcinoma (HCC), is one of common malignancies worldwide, and prevalent among the Chinese population. A diagnosis of early stage HCC has proven to be very difficult because of its insidious feature in onset and development. At the time of diagnosis, most HCC cases are locally advanced and/or distant metastatic, which results in difficulty to be treated and poor prognosis. For advanced HCC, systemic therapy is frequently adopted as an important palliative method. In recent years, clinical studies and observations have often reported about systemic anti-cancer therapy of advanced HCC, including molecular target therapy, systemic chemotherapy and immunotherapy. In this article, we review these treatment modalities to provide a reference for clinicians.

Project description:Patients with advanced hepatocellular carcinoma (HCC) have several systemic treatment options. There are many known risk factors for HCC, and although some, such as hepatitis C, are now treatable, others are not. For example, metabolic dysfunction-related chronic liver disease is increasing in incidence and has no specific treatment. Underlying liver disease, drug resistance, and an increasing number of treatment options without specific biomarkers are all challenges in selecting the best treatment for each patient. Conventional chemotherapy is almost never used for advanced-stage disease, which instead is treated with immunotherapy, tyrosine kinase inhibitors, and VEGF inhibitors. Immune checkpoint inhibitors targeting various receptors have been or are currently undergoing clinical evaluation. Ongoing trials with three-drug regimens may be the future of advanced-stage HCC treatment. Other immune-modulatory approaches of chimeric antigen receptor-modified T cells, bispecific antibodies, cytokine-induced killer cells, natural killer cells, and vaccines are in early-stage clinical trials. Targeted therapies remain limited for HCC but represent an area of potential growth. As we shift away from first-line sorafenib for advanced HCC, clinical trial control arms should comprise a standard treatment other than sorafenib, one that is a better comparator for advancing therapies.

Project description:Many potential systemic therapies are being investigated for the treatment of hepatocellular carcinoma (HCC). The incidence of this malignancy is rising sharply and the vast majority of patients present at advanced stages. Although the earlier dismal results with cytotoxic chemotherapies made way for the development of locoregional therapies that provided improved overall survival, truly personalized therapy will require the selection of phenotypically similar stages of disease and populations, an understanding of the complex molecular and genetic pathways leading to HCC, and a keen understanding of the pathobiology of cirrhosis. Only then will we understand how to offer a particular patient at a specific stage of disease the appropriate therapy to truly prolong survival.

Project description:Hepatocellular carcinoma often develops in the context of chronic liver disease. It is the sixth most frequently diagnosed cancer and the third most common cause of cancer-related mortality worldwide. Although the mainstay of therapy is surgical resection, most patients are not eligible because of liver dysfunction or tumor extent. Sorafenib was the first tyrosine kinase inhibitor that improved the overall survival of patients who failed to respond to local therapies or had advanced disease, and for many years, it was the only treatment approved for the first-line setting. However, in recent years, trials have demonstrated an improvement in survival with treatments based on immunotherapy and new targeting agents, thereby extending the treatment options. A phase III trial showed that a combination of immunotherapy and targeted therapy, including atezolizumab plus bevacizumab, improved survival in the first-line setting, and is now considered the new standard of care. Other agents and combinations are being tested, including the combination of nivolumab plus ipilimumab and tremelimumab plus durvalumab, and they reportedly have clinical benefits. The aim of this manuscript is to review the latest approved therapeutic options in first- and second-line settings for advanced HCC and discuss future perspectives.

Project description:BackgroundADVANCED HEPATOCELLULAR CARCINOMA (HCC) IS A MALIGNANCY OF GLOBAL IMPORTANCE: it is the sixth most common cancer and the third most common cause of cancer-related mortality worldwide. Despite decades of efforts by many investigators, systemic chemotherapy or hormone therapy has failed to demonstrate improved survival in patients with HCC.. Ongoing studies are evaluating the efficacy and tolerability of combining Sorafenib with erlotinib and other targeted agents or chemotherapy.AimsOn the basis of placebo-controlled, randomized phase III trials, Sorafenib has shown improved survival benefits in advanced HCC and has set a new standard for future clinical trials. The successful clinical development of Sorafenib in HCC has ushered in the era of molecularly targeted agents in this disease, which is discussed in this educational review.Material and methodsMany molecularly targeted agents that inhibit angiogenesis, epidermal growth factor receptor, and mammalian target of rapamycin are at different stages of clinical development in advanced HCC. Future research should continue to unravel the mechanism of hepatocarcinogenesis and to identify key relevant molecular targets for therapeutic intervention. Identification and validation of potential surrogate and predictive biomarkers hold promise to individualize patients' treatment to maximize clinical benefit and minimize the toxicity and cost of targeted agents.ResultsSystemic therapy with various classes of agents, including hormone and cytotoxic agents, has provided no or marginal benefits. Improved understanding of the mechanism of hepatocarcinogenesis, coupled with the arrival of many newly developed molecularly targeted agents, has provided the unique opportunity to study some of these novel agents in advanced HCC.ConclusionsThe demonstration of improved survival benefits by Sorafenib in advanced HCC has ushered in the era of molecular-targeted therapy in this disease, with many agents undergoing active clinical development.

Project description:BackgroundPatients with advanced hepatocellular carcinoma (HCC) have a poor prognosis. First-line sorafenib has been the standard of care for a decade, but the treatment landscape is expanding. This review provides a practical overview of current and future systemic treatment options for advanced HCC and their place in clinical practice.SummaryFirst-line sorafenib and lenvatinib have shown to improve the survival of patients with advanced HCC. In the second line, regorafenib provides benefit for patients who previously tolerated sorafenib. Anti-PD1 antibodies, nivolumab and pembrolizumab, recently became available for second-line use in the US. Ramucirumab (for patients with α-fetoprotein [AFP] levels ≥400) and cabozantinib present potential future second-line treatment options. Combinations of systemic and locoregional treatment, such as radiofrequency ablation or selective internal radiotherapy, require further research. Precision medicine has not yet been translated into clinical practice, as the most common driver mutations (TERT promoter, CTNNB1, TP53, and ARID1A mutations) have not yet been shown to be suitable therapeutic targets. However, our growing understanding of signaling pathways and efforts in drug development are expected to pave the way for precision medicine in HCC in the future. Evaluating the place for the current and novel systemic treatment options in clinical practice can be challenging due to the diverse toxicity profiles of the treatment options and characteristics of the patient population. Sorafenib data elucidate the effect patient characteristics (such as the performance score, Child-Pugh class, AFP, etiology of the underlying disease, and level of macrovascular invasion and extrahepatic spread) may have on outcomes in advanced stages.Key messagesLenvatinib is expected to join sorafenib as a preferred first-line treatment in advanced HCC. In the second line, the treatment of choice, regorafenib, is soon expected to be accompanied by cabozantinib and ramucirumab in patients with AFP ≥400 ng/mL, whereas nivolumab and pembrolizumab present second-line alternatives in the US.

Project description:Several molecular-targeted agents have been tested as first- or second-line therapies for hepatocellular carcinoma (HCC) but failed to improve clinical outcomes; sorafenib has been the only approved systemic agent for treating HCC for almost 10 years. Regorafenib resulted in a significant improvement in overall survival and thus was approved for HCC patients previously treated with sorafenib. Subsequently, cabozantinib and ramucirumab demonstrated superior overall survival compared with placebos in phase III clinical trials. Immune checkpoint inhibitors such as nivolumab with or without ipilimumab and pembrolizumab are also available in some countries for patients who are unresponsive to sorafenib. Some second-line agents are available for patients who are unresponsive to sorafenib; however, little is known about the considerations for selecting appropriate second-line systemic agents. Hence, this study aimed to review the current and future perspectives of second-line systemic agents.
