Abstract
Most patients with hepatocellular carcinoma (HCC) have a poor prognosis. Hepatectomy and local ablation are the main curative treatments for HCC. Nevertheless, the recurrence rate after hepatectomy or ablation is up to 70%, which seriously affects patient prognosis. Several adjuvant therapies have been explored to reduce postoperative recurrence. However, although a variety of adjuvant therapies have been shown to reduce the recurrence rate and improve overall survival, a standard consensus of national HCC guidelines for adjuvant treatment is lacking. Therefore, there are significant differences in the recommendations for adjuvant therapy for HCC between the Eastern and Western guidelines. A variety of adjuvant treatment methods, such as antiviral therapy, transarterial chemoembolization or traditional Chinese medicine, are recommended by the Chinese HCC guidelines. However, Western guidelines make few recommendations other than antiviral therapy. Adjuvant immune checkpoint inhibitors are recommended only in the recently updated American Association for the Study of Liver Diseases guidelines. This review summarized the existing adjuvant therapy options after curative hepatectomy or ablation and discusses several important dilemmas of adjuvant treatments.

Ye Y, Wang Y, Xu H, Yi F. Network meta-analysis of adjuvant treatments for patients with hepatocellular carcinoma after curative resection. BMC Gastroenterol 2023; 23:320. [PMID: 37730533 PMCID: PMC10510134 DOI: 10.1186/s12876-023-02955-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Accepted: 09/10/2023] [Indexed: 09/22/2023] Open
Abstract
PURPOSE The prevention of recurrence for patients with hepatocellular carcinoma after curative resection is still a great challenge in clinical practice. There are numerous studies that trying to search for favorable strategies to decrease the recurrence and prolong life span for these patients, whereas no consensus is reached till now. Herein, we aim to compare the efficacy between different reported treatments by network meta-analysis(NMA). METHODS We searched Pubmed, Web of Science and Cochrane Library for abstracts and full-text articles published from database inception through February 2023. All of the random controlled trials(RCTs) were evaluated and collected as eligible studies. The primary outcome was the prevention of recurrence between different procedures. The second outcomes were one-year survival, three-year survival and five-year survival. RESULTS Thirty-two RCTs including 5783 patients were selected, and 12 treatments were classified. Most of the studies were high quality with low bias. Thirty-one studies including 5629 patients were recruited for recurrence analysis. The network meta-analysis showed benefits from transarterial chemoembolization(TACE) + portal vein chemotherapy(PVC)[OR, 2.84 (1.15,6.99)] and internal radiotherapy(IRT) [OR, 2.63 (1.41,4.91)] compared to non-adjuvant(NA) treatment when considering prevention of recurrence. Seventeen studies including 2047 patients were collected for one-year survival analysis. The network meta-analysis showed benefit from TACE[OR, 0.33 (0.14,0.75)] when considering one-year survival. Twenty-one studies including 2463 patients were collected for three-year survival analysis. The network meta-analysis showed TACE [OR, 0.51 (0.30,0.86)], IRT[OR, 0.41 (0.20,0.83)] and dendritic cell(DC) [OR, 0.09 (0.01,0.98)] were better than NA when considering three-year survival. Sixteen studies including 1915 patients were collected for five-year survival analysis. The network meta-analysis didn't show any benefit from different treatments when considering five-year survival. Other strategies including external radiotherapy(ERT), branched-chain amino acids(BCAA), hepatic artery infusion chemotherapy(HAIC), cytokine-induced killer(CIK), adoptive immunotherapy(AIT), Huaier, interferon(IFN), oral chemotherapy(OCT) and sorafenib(SOR) didn't show significant benefit regardless of prevention of recurrence or short-, long- time survival. CONCLUSION This NMA found that TACE + PVC and IRT were considered as the procedures to decrease HCC recurrence rate. TACE, IRT and DC were preferred when considering the extending of life span for post-operative patients with HCC. Large scale of RCTs are needed to verify it.

Abstract
Owing to its heterogeneous and highly aggressive nature, hepatocellular carcinoma (HCC) has a high recurrence rate, which is a non-negligible problem despite the increasing number of available treatment options. Recent clinical trials have attempted to reduce the recurrence and develop innovative treatment options for patients with recurrent HCC. In the event of liver remnant recurrence, the currently available treatment options include repeat hepatectomy, salvage liver transplantation, tumor ablation, transcatheter arterial chemoembolization, stereotactic body radiotherapy, systemic therapies, and combination therapy. In this review, we summarize the strategies to reduce the recurrence of high-risk tumors and aggressive therapies for recurrent HCC. Additionally, we discuss methods to prevent HCC recurrence and prognostic models constructed based on predictors of recurrence to develop an appropriate surveillance program.

Abstract
Hepatocellular carcinoma (HCC) is a highly heterogeneous, invasive, and conventional chemotherapy-insensitive tumor with unique biological characteristics. The main methods for the radical treatment of HCC are surgical resection or liver transplantation. However, recurrence rates are as high as 50% and 70% at 3 and 5 years after liver resection, respectively, and even in Milan-eligible recipients, the recurrence rate is approximately 20% at 5 years after liver transplantation. Therefore, reducing the postoperative recurrence rate is key to improving the overall outcome of liver cancer. This review discusses the risk factors for recurrence in patients with HCC radical surgical resection and adjuvant treatment options that may reduce the risk of recurrence and improve overall survival, including local adjuvant therapy (e.g., transcatheter arterial chemoembolization), adjuvant systemic therapy (e.g., molecular targeted agents and immunotherapy), and other adjuvant therapies (e.g., antiviral and herbal therapy). Finally, potential research directions that may change the paradigm of adjuvant therapy for HCC are analyzed.

Abstract
Carmofur, 1-hexylcarbamoyl-5-fluorouracil (HCFU) is an antineoplastic drug, which has been in clinics in Japan since 1981 for the treatment of colorectal cancer. Subsequently, it was also introduced in China, Korea, and Finland. Besides colorectal cancer, it has also shown antitumor activity in other cancers such as breast, head and neck, pancreatic, gastrointestinal, and solid brain tumors. A prodrug of 5-fluorouracil (5-FU), carmofur has shown better gastrointestinal stability and superior antiproliferative activity compared to its active counterpart 5-FU. Recently, carmofur has gained attention as an acid ceramidase inhibitor and as a potential lead compound against several noncancerous diseases such as coronavirus disease 2019, Krabbe disease, acute lung injury, Parkinson's disease, dementia, childhood ependymoma etc. Carmofur has also been reported to have antifungal, and antimicrobial properties. Nevertheless, no comprehensive review is available on this drug. Herein, we summarized the chemistry, pharmacokinetics, and pharmacology of carmofur based on the literature published between January 1976 and March 2022 as identified from PubMed and Google Scholar search engines.

Abstract
Hepatectomy and transplantation are the main surgical therapies for HCC patients, and radiotherapy or chemotherapy is often used as adjuvant treatment. Researches have evaluated the independent predictors of HCC, but evidence for factors predicting the efficacy of chemotherapy is rare. Patients diagnosed with HCC between 2010 and 2015 from the SEER database were included and randomly divided into non-chemotherapy and chemotherapy groups. The predictors of CSS and OS were analyzed with the Cox proportional-hazards regression model and Fine and Gray’s competing risk model. Although there was no significant difference in survival analysis between the chemotherapy and non-chemotherapy groups, the cumulative cancer-specific mortality of most HCC patients was decreased in the chemotherapy group. AJCC stage, tumor size, grade, surgery and radiotherapy were predictors of OS and CSS in the non-chemotherapy group, while AJCC stage, tumor size, AFP, grade and surgery in the chemotherapy group. Surgery combined with chemotherapy was applicable to all AJCC stage patients. Surgery was the major treatment option for patients in AJCC I and AJCC II stage, and chemotherapy in AJCC III and AJCC IV stage. In conclusion, the study provided population-based estimates of the prognostic factors in HCC patients with or without chemotherapy.

Abstract
Background It is controversial whether adjuvant treatment could be recommended for hepatocellular carcinoma (HCC) after curative hepatectomy. Thus, we performed a network meta-analysis (NMA) to assess adjuvant treatment’s benefit and determine the optimal adjuvant regimen. Methods We systematically searched PubMed, Embase, and Cochrane Library for randomized controlled trials comparing adjuvant therapy versus no active treatment after curative hepatectomy among patients with HCC. Pooled data on recurrence and overall survival (OS) were analyzed within pairwise meta-analysis and NMA. Results Twenty-three eligible trials (3,940 patients) reporting eight treatments were included. The direct meta-analysis showed that adjuvant therapy prevented the recurrence (OR = 0.65; 95% CI: 0.55, 0.77; P = 0.177; I2 = 21.7%) and contributed to OS (HR = 0.63; 95% CI: 0.54, 0.73; P = 0.087; I2 = 31.1%) in comparison to the observation. In the NMA, internal radiotherapy (IRT; OR = 0.55; 95% CI: 0.39, 0.77; SUCRA = 87.7%) followed by hepatic artery infusion chemotherapy (HAIC; OR = 0.6; 95% CI: 0.36, 0.97; SUCRA = 77.8%), and HAIC (HR = 0.44; 95% CI: 0.21, 0.87; SUCRA = 82.6%) followed by IRT (HR 0.54; 95% CI:0.36, 0.81; SUCRA = 69.7%) were ranked superior to other treatments in terms of preventing recurrence and providing survival benefit, respectively. Conclusions The addition of adjuvant therapy lowers the risk of recurrence and provide survival benefit after surgical resection for HCC. HAIC and IRT are likely to be the two most effective adjuvant regimens. Systematic Review Registration https://inplasy.com/inplasy-2020-11-0039/.

Abstract
Although the inhibition of acid ceramidase (AC) is known to induce antitumor effects in various cancers, there are few reports in pancreatic cancer, and the underlying mechanisms remain unclear. Moreover, there is currently no safe administration method of AC inhibitor. Here the effects of gene therapy using siRNA and shRNA for AC inhibition with its mechanisms for pancreatic cancer were investigated. The inhibition of AC by siRNA and shRNA using an adeno-associated virus 8 (AAV8) vector had antiproliferative effects by inducing apoptosis in pancreatic cancer cells and xenograft mouse model. Acid ceramidase inhibition elicits mitochondrial dysfunction, reactive oxygen species accumulation, and manganese superoxide dismutase suppression, resulting in apoptosis of pancreatic cancer cells accompanied by ceramide accumulation. These results elucidated the mechanisms underlying the antitumor effect of AC inhibition in pancreatic cancer cells and suggest the potential of the AAV8 vector to inhibit AC as a therapeutic strategy.

Abstract
BACKGROUND The impact of tumor burden score (TBS) on conditional survival (CS) among patients undergoing curative-intent resection of hepatocellular carcinoma (HCC) has not been examined to date. METHODS Patients who underwent liver resection of HCC between 2000 and 2017 were identified from a multi-institutional database. The impact of TBS and other clinicopathologic factors on 3-year conditional survival (CS3) was examined. RESULTS Among 1,040 patients, 263 (25.3%) patients had low TBS, 668 (64.2%) had medium TBS and 109 (10.5%) had high TBS. TBS was strongly associated with OS; 5-year OS was 39.0% among patients with high TBS compared with 61.1% and 79.4% among patients with medium and low TBS, respectively (p < 0.001). While actuarial survival decreased as time elapsed from resection, CS increased over time irrespective of TBS. The largest differences between 3-year actuarial survival and CS3 were noted among patients with high TBS (5-years postoperatively; CS3: 78.7% vs. 3-year actuarial survival: 30.7%). The effect of adverse clinicopathologic factors including high TBS, poor/undifferentiated tumor grade, microvascular invasion, liver capsule involvement, and positive margins on prognosis decreased over time. CONCLUSIONS CS rates among patients who underwent resection for HCC increased as patients survived additional years, irrespective of TBS. CS estimates can be used to provide important dynamic information relative to the changing survival probability after resection of HCC.

Abstract
Hepatic resection represents the first-line treatment for patients with resectable hepatocellular carcinoma (HCC). However, the 5-year recurrence rates of HCC after surgery have been reported to range from 50% to 70%. In this review, we evaluated the available evidence for the efficiency of adjuvant treatments to prevent HCC recurrence after curative liver resection. Antiviral therapy has potential advantages in terms of reducing the recurrence rate and improving the overall survival (OS) and/or disease-free survival of patients with hepatitis-related HCC. Postoperative adjuvant transarterial chemoembolization can significantly reduce the intrahepatic recurrence rate and improve OS, especially for patients with a high risk of recurrence. The efficacy of molecular targeted drugs as an adjuvant therapy deserves further study. Adjuvant adoptive immunotherapy can significantly improve the clinical prognosis in the early stage. Randomized controlled trial (RCT) studies evaluating adjuvant immune checkpoint inhibitors are ongoing, and the results are highly expected. Adjuvant hepatic artery infusion chemotherapy might be beneficial in patients with vascular invasion. Huaier granule, a traditional Chinese medicine, has been proved to be effective in prolonging the recurrence-free survival and reducing extrahepatic recurrence. The efficiency of other adjuvant treatments needs to be further confirmed by large RCT studies.

Abstract
Hepatocellular carcinoma (HCC) is a lethal malignancy with poor prognosis. More than 80% of patients are diagnosed at an advanced stage, and most patients with HCC also have liver cirrhosis that complicates cancer management. No targeted treatment options currently exist outside genomics-based clinical trials. Multiple tyrosine kinase inhibitors (mTKIs) such as sorafenib, lenvatinib, cabozantinib, and regorafenib have been used to treat advanced hepatocellular carcinoma (aHCC). Immune checkpoint inhibitors including nivolumab and pembrolizumab have shown survival benefit. More recently, atezolizumab in combination with bevacizumab resulted in improved overall survival and progression-free survival, compared with sorafenib in patients with aHCC in the first-line setting. The combination of nivolumab with ipilimumab as an alternative in the treatment of patients treated with sorafenib has inspired various combination studies of immune checkpoint inhibitors. Currently, ongoing studies of systemic therapy consist of various immune-based combination therapies. Finally, there is no established adjuvant and neoadjuvant therapy although a few early phase studies show promising results. In this chapter, we summarize current approaches of systemic treatment in patients with liver cancer.

[PMID: 35118033 PMCID: PMC8804370 DOI: 10.3389/fped.2021.807973] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Accepted: 12/24/2021] [Indexed: 01/10/2023] Open
Abstract
Krabbe disease is a lysosomal storage disease that is caused by a deficiency in galactosylceramidase. Infantile onset disease is the most common presentation, which includes progressive neurological deterioration with corresponding demyelination, development of globoid cells, astrocyte gliosis, etc. Hemopoietic stem cell transplantation (HSCT) is a disease modifying therapy, but this intervention is insufficient with many patients still experiencing developmental delays and progressive deterioration. Preclinical studies have used animal models, e.g., twitcher mice, to test different experimental therapies resulting in developments that have led to progressive improvements in the therapeutic impact. Some recent advances have been in the areas of gene therapy and substrate reduction therapy (SRT), as well as using these in combination with HSCT. Unfortunately, new experimental approaches have encountered obstacles which have impeded the translation of novel therapies to human patients. In an effort to identify a safe adjunct therapy, D-cycloserine was tested in preliminary studies in twitcher mice. When administered as a standalone therapy, D-cycloserine was shown to lengthen the lifespan of twitcher mice in a small but significant manner. D-Cycloserine is an FDA approved antibiotic used for drug resistant tuberculosis. It also acts as a partial agonist of the NMDA receptor, which has led to numerous human studies for a range of neuropsychiatric and neurological conditions. In addition, D-cycloserine may inhibit serine palmitoyltransferase (SPT), which catalyzes the rate-limiting step in sphingolipid production. The enantiomer, L-cycloserine, is a much more potent inhibitor of SPT than D-cycloserine. Previously, L-cycloserine was found to act as an effective SRT agent in twitcher mice as both a standalone therapy and as part of combination therapies. L-Cycloserine is not approved for human use, and its potent inhibitory properties may limit its ability to maintain a level of partial inactivation of SPT that is also safe. In theory, D-cycloserine would encompass a much broader dosage range to achieve a safe degree of partial inhibition of SPT, which increases the likelihood it could advance to human studies in patients with Krabbe disease. Furthermore, additional properties of D-cycloserine raise the possibility of other therapeutic mechanisms that could be exploited for the treatment of this disease.

Targeting Acid Ceramidase to Improve the Radiosensitivity of Rectal Cancer. Cells 2020; 9:E2693. [PMID: 33334013 PMCID: PMC7765421 DOI: 10.3390/cells9122693] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 12/12/2020] [Accepted: 12/14/2020] [Indexed: 12/12/2022] Open
Abstract
Previous work utilizing proteomic and immunohistochemical analyses has identified that high levels of acid ceramidase (AC) expression confers a poorer response to neoadjuvant treatment in locally advanced rectal cancer. We aimed to assess the radiosensitising effect of biological and pharmacological manipulation of AC and elucidate the underlying mechanism. AC manipulation in three colorectal cancer cell lines (HT29, HCT116 and LIM1215) was achieved using siRNA and plasmid overexpression. Carmofur and a novel small molecular inhibitor (LCL521) were used as pharmacological AC inhibitors. Using clonogenic assays, we demonstrate that an siRNA knockdown of AC enhanced X-ray radiosensitivity across all colorectal cancer cell lines compared to a non-targeting control siRNA, and conversely, AC protein overexpression increased radioresistance. Using CRISPR gene editing, we also generated AC knockout HCT116 cells that were significantly more radiosensitive compared to AC-expressing cells. Similarly, two patient-derived organoid models containing relatively low AC expression were found to be comparatively more radiosensitive than three other models containing higher levels of AC. Additionally, AC inhibition using carmofur and LCL521 in three colorectal cancer cell lines increased cellular radiosensitivity. Decreased AC protein led to significant poly-ADP ribose polymerase-1 (PARP-1) cleavage and apoptosis post-irradiation, which was shown to be executed through a p53-dependent process. Our study demonstrates that expression of AC within colorectal cancer cell lines modulates the cellular response to radiation, and particularly that AC inhibition leads to significantly enhanced radiosensitivity through an elevation in apoptosis. This work further solidifies AC as a target for improving radiotherapy treatment of locally advanced rectal cancer.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is among the world's most common cancers. For over ten years, the only medical treatment for it has been the multikinase inhibitor Sorafenib. Currently, however, other first or second-line therapeutic options have also shown efficacy against HCC, such as multikinase inhibitors (Regorafenib, Lenvatinib, and Cabozantinib), a monoclonal antibody against the vascular endothelial growth factor receptor 2 (Ramucirumab), and immune-checkpoint inhibitors (Nivolumab, Pembrolizumab, Ipilimumab). AIM The aim of this paper is to review the metabolic pathways of drugs that have been tested for the treatment of HCC and the potential influence of liver failure over those pathways. METHODS The Food and Drug Administration (FDA)'s and European Medicines Agency (EMA)'s datasheets, results from clinical trials and observational studies have been reviewed. RESULTS This review summarizes the current knowledge regarding targets, metabolic pathways, drug interactions, and adverse events of medical treatments for HCC in cirrhotic patients. CONCLUSION The new scenario of systemic HCC therapy includes more active drugs with different metabolic pathways and different liver adverse events. Clinical and pharmacological studies providing more data on the safety of these molecules are urgently needed.

Abstract
Introduction: The 5-year recurrence rate of hepatocellular carcinoma (HCC) after hepatic resection or local ablation is up to 70%. Adjuvant therapies to prevent HCC recurrence have been reported but are not currently recommended by EASL or AASLD guidelines. This review examined evidence from randomized controlled trials, meta-analyses and systematic reviews on the safety and efficacy of adjuvant therapies and chemotherapies in HCC patients after resection or local ablation.Areas covered: PubMed was searched through 15 June 2019. Available evidence was assessed based on the GRADE system.Expert commentary: Transarterial chemoembolization is the best adjuvant therapy for HCC patients at high risk of recurrence, antiviral therapy with nucleoside analogs is effective for preventing recurrence of HBV-related HCC, and interferon-α is effective for preventing recurrence of HCV-related HCC. Further studies are needed to clarify the efficacy of adjuvant immune checkpoint inhibitors. Adjuvant sorafenib appears to offer negligible clinical benefit and high risk of adverse effects.

Abstract
Hepatocellular carcinoma (HCC) is the most common liver malignancy worldwide and a major cause of cancer-related mortality for which liver resection is an important curative-intent treatment option. However, many patients present with advanced disease and with underlying chronic liver disease and/or cirrhosis, limiting the proportion of patients who are surgical candidates. In addition, the development of recurrent or de novo cancers following surgical resection is common. These issues have led investigators to evaluate the benefit of neoadjuvant and adjuvant treatment strategies aimed at improving resectability rates and decreasing recurrence rates. While high-level evidence to guide treatment decision making is lacking, recent advances in locoregional and systemic therapies, including antiviral treatment and immunotherapy, raise the prospect of novel approaches that may improve the outcomes of patients with HCC. In this review, we evaluate the evidence for various neoadjuvant and adjuvant therapies and discuss opportunities for future clinical and translational research.

Abstract
BACKGROUND Sphingolipids have been shown to play a key part in cancer cell growth and death and have increasingly become the subject of novel anti-cancer therapies. Acid ceramidase, a sphingolipid enzyme, has an important role in the regulation of apoptosis. In this review we aim to assess the current evidence supporting the role of sphingolipids in cancer and the potential role that acid ceramidase may play in cancer treatment. METHODS A literature search was performed for published full text articles using the PubMed, Cochrane and Scopus databases using the search criteria string "acid ceramidase", "sphingolipid", "cancer". Additional papers were detected by scanning the references of relevant papers. A summary of the evidence for each cancer subgroup was then formed. Given the nature of the data extracted, no meta-analysis was performed. RESULTS Over expression of acid ceramidase has been demonstrated in a number of human cancers. In vitro data demonstrate that manipulation of acid ceramidase may present a useful therapeutic target. In the clinical setting, a number of drugs have been investigated with the ability to target acid ceramidase, with the most promising of those being small molecular inhibitors, such as LCL521. CONCLUSION The role of the sphingolipid pathway in cancer is becoming very clearly established by promoting ceramide accumulation in response to cancer or cellular stress. Acid ceramidase is over expressed in a variety of cancers and has a role as a potential target for inhibition by novel specific inhibitors or off-target effects of traditional anti-cancer agents. Further work is required to develop acid ceramidase inhibitors safe for progression to clinical trials.

Abstract
Intraoperative bleeding is an essential factor leading to the earliest recurrence and tumor metastasis frequently seen after resection of solid tumors. Local drug delivery implants show the unique advantages on postoperative cancer therapy. Herein, a sandwich-like cisplatin-loaded fibers/sponge composite (CFSC) combining chemotherapy and hemostasis is constructed. The obtained implantable CFSC is able to simultaneously stop bleeding and absorb disseminated tumor cells after tumor resection. More importantly, sustained released cisplatin can kill local residual tumor cells as well as those concentrated in the CFSC, which significantly inhibits local tumor recurrence and distant tumor metastasis on the subcutaneous postoperative recurrence model and metastasis models. This dual functional implant strategy with low toxicity to healthy organs may inspire new aspects for efficient postoperative cancer therapy.

Adjuvant transcatheter arterial chemoembolization after curative resection for hepatocellular carcinoma patients with solitary tumor and microvascular invasion: a randomized clinical trial of efficacy and safety. Cancer Commun (Lond) 2018; 38:61. [PMID: 30305149 PMCID: PMC6235393 DOI: 10.1186/s40880-018-0331-y] [Citation(s) in RCA: 53] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Accepted: 09/28/2018] [Indexed: 02/06/2023] Open
Abstract
Background The optimal strategy for adjuvant therapy after curative resection for hepatocellular carcinoma (HCC) patients with solitary tumor and microvascular invasion (MVI) is controversial. This trial evaluated the efficacy and safety of adjuvant transcatheter arterial chemoembolization (TACE) after hepatectomy versus hepatectomy alone in HCC patients with a solitary tumor ≥ 5 cm and MVI. Methods In this randomized, open-labeled, phase III trial, HCC patients with a solitary tumor ≥ 5 cm and MVI were randomly assigned (1:1) to receive either 1–2 cycles of adjuvant TACE after hepatectomy (Hepatectomy-TACE) or hepatectomy alone (Hepatectomy Alone). The primary endpoint was disease-free survival (DFS); the secondary endpoints included overall survival (OS) and adverse events. Results Between June 1, 2009, and December 31, 2012, 250 patients were enrolled and randomly assigned to the Hepatectomy-TACE group (n = 125) or the Hepatectomy Alone group (n = 125). Clinicopathological characteristics were balanced between the two groups. The median follow-up time from randomization was 37.5 months [interquartile range 18.3–48.2 months]. The median DFS was significantly longer in the Hepatectomy-TACE group than in the Hepatectomy Alone group [17.45 months (95% confidence interval [CI] 11.99–29.14) vs. 9.27 months (95% CI 6.05–13.70), hazard ratio [HR] = 0.70 (95% CI 0.52–0.95), P = 0.020], respectively. The median OS was also significantly longer in the Hepatectomy-TACE group than in the Hepatectomy Alone group [44.29 months (95% CI 25.99–62.58) vs. 22.37 months (95% CI 10.84–33.91), HR = 0.68 (95% CI 0.48–0.97), P = 0.029]. Treatment-related adverse events were more frequently observed in the Hepatectomy-TACE group, although these were generally mild and manageable. The most common grade 3 or 4 adverse events in both groups were neutropenia and liver dysfunction. Conclusion Hepatectomy followed by adjuvant TACE is an appropriate option after radical resection in HCC patients with solitary tumor ≥ 5 cm and MVI, with acceptable toxicity.

[PMID: 29110700 PMCID: PMC5674853 DOI: 10.1186/s12885-017-3707-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2017] [Accepted: 10/27/2017] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Many studies have combined sorafenib with transcatheter arterial chemoembolization (TACE) to treat patients with advanced hepatocellular carcinoma (HCC), but the results are disputable. Thus, we conducted this meta-analysis to assess the efficacy and safety of the combination treatment in patients with advanced HCC. METHODS Clinical data were collected from a computer search of literature published from January 2009 to June 2016 in PubMed, Web of Science, the Cochrane Library, China National Knowledge Infrastructure (CNKI), Wan Fang and the China Science and Technology Journal Database (CSTJ). The final analysis included 14 studies and 1670 patients. The primary endpoints were overall survival (OS), the objective response rate (ORR) and the disease control rate (DCR). RESULTS The combination group exhibited significantly more improvement than the group treated with TACE alone in ORR (RR =1.62, 95% confidence interval (CI) = 1.34-1.94, p < 0.00001), DCR (RR = 1.43, 95% CI = 1.26-1.62, p < 0.00001), 0.5-year OS (OR = 2.60, 95% CI = 1.57-4.29, p = 0.0002) and 1-year OS (OR = 1.88, 95% CI =1.39-2.53, p < 0.0001). The incidence of adverse events from combination therapy was increased compared to that from treatment with TACE alone, and the most commonly reported adverse events were fatigue, hand-foot skin reaction and diarrhoea, which were bearable. CONCLUSIONS The meta-analysis indicated that combination therapy is safe and efficient for clinical application.

Abstract
Nucleoside, nucleotide, and base analogs have been in the clinic for decades to treat both viral pathogens and neoplasms. More than 20% of patients on anticancer chemotherapy have been treated with one or more of these analogs. This review focuses on the chemical synthesis and biology of anticancer nucleoside, nucleotide, and base analogs that are FDA-approved and in clinical development since 2000. We highlight the cellular biology and clinical biology of analogs, drug resistance mechanisms, and compound specificity towards different cancer types. Furthermore, we explore analog syntheses as well as improved and scale-up syntheses. We conclude with a discussion on what might lie ahead for medicinal chemists, biologists, and physicians as they try to improve analog efficacy through prodrug strategies and drug combinations.

Abstract
Objectives Major adjuvant therapies (ATs) for resected hepatocellular carcinoma (HCC) include chemotherapy, internal radiation therapy (IRT), interferon therapy (IFNT) and immunotherapy but the optimum regimen remains inconclusive. We aim to compare these therapies in terms of patient survival and recurrence rates. Methods We searched PubMed, EMBASE and Cochrane library databases for randomized trials comparing the above four therapies until 31 March 2014. We estimated the HRs for survival and ORs for overall recurrence among different therapies. Toxic effects were also evaluated. Results Fourteen eligible articles were included. IFNT improved 5-year survival greatly (HR 1.81, 95% CI 1.01–3.81, P = 0.034), whereas chemotherapy (HR 0.33, 95% CI 0.03–2.02), IRT (HR 0.31, 95% CI 0.02–3.33) and immunotherapy (HR 0.73, 95% CI 0.05–9.12) all provided a poorer survival outcome after 1-year. Similarly, for 5-year survival rates, although differing, IRT did not provide a significant improvement in survival (HR 1.38, 95% CI 0.34–5.19) compared with IFNT. Chemotherapy (HR 0.49, 95% CI 0.18–1.14) and immunotherapy (HR 0.56, 95% CI 0.17–1.59) did not appear to provide benefit over IFNT. Chemotherapy was ranked the worst in overall recurrence (OR 0.99, 95% CI 0.18–5.38) and most likely to cause toxic effects. Conclusions IFNT was the most efficacious AT regimen both for short and long term survivals. Immunotherapy and IFNT were the most two effective in preventing overall relapse for resected HCC.

Abstract
Hepatocellular carcinoma (HCC), the second leading cause of cancer deaths worldwide, is difficult to treat and highly lethal. Since HCC is predominantly diagnosed in patients with cirrhosis, treatment planning must consider both the severity of liver disease and tumor burden. To minimize the impact to the patient while treating the tumor, techniques have been developed to target HCC. Anatomical targeting by surgical resection or locoregional therapies is generally reserved for patients with preserved liver function and minimal to moderate tumor burden. Patients with decompensated cirrhosis and small tumors are optimal candidates for liver transplantation, which offers the best chance of long-term survival. Yet, only 20%-30% of patients have disease amenable to anatomical targeting. For the majority of patients with advanced HCC, chemotherapy is used to target the tumor biology. Despite these treatment options, the five-year survival of patients in the United States with HCC is only 16%. In this review we provide a comprehensive overview of current approaches to target HCC. We also discuss emerging diagnostic and prognostic biomarkers, novel therapeutic targets identified by recent genomic profiling studies, and potential applications of immunotherapy in the treatment of HCC.

Abstract
Hepatocellular carcinoma (HCC) is a common malignancy in the world. Although resection and various locoregional therapies can achieve eradication or complete ablation of small HCC, HCC recurrence after these therapies is still common. Although candidates for medical ablation usually exhibit compensated hepatic functional status, the frequent recurrence of HCC after successful ablation contributes to short survival. Therefore, attempts to prevent HCC recurrence are essential to prolong survival. Efforts in preventing HCC recurrence after curative therapies include prevention of early recurrence by improving liver immunity and eliminating microscopic tumor foci or micrometastases, and prevention of late recurrence by reducing the hepatitis activity and using antiviral therapies based on viral suppression/eradication. In HCC with vascular invasion, adjuvant transcatheter arterial chemoembolization should be considered to provide better control. Whether the adjuvant use of sorafenib may suppress microscopic tumor foci or micrometastases may be unveiled in the near future. This review article will update the algorithms, novel medication or study drugs in the prevention of HCC after curative therapies.

Abstract
The recurrence rate of hepatocellular carcinoma (HCC) after potentially curative hepatic resection (HR) is very high. Many clinical trials have explored the efficacy of several treatment modalities to prevent recurrence, including adjuvant and chemopreventive therapy, but they have often reported contradictory findings. As a result, most liver guidelines and liver seminars do not unequivocally endorse adjuvant or chemopreventive therapy for HCC patients after potentially curative HR. To examine the available evidence on this question, we comprehensively searched PubMed for controlled studies that included a supportive care or placebo control arm, and we used the GRADE system to classify and assess the results.

Abstract
The findings of randomized clinical trials (RCTs) regarding the efficacy of adjuvant conventional oral systemic chemotherapy (COSC) for patients with hepatocellular carcinoma (HCC) following curative hepatic resection (HR) are contradictory. Therefore, a systematic review of RCTs is required to evaluate the clinical efficacy of adjuvant COSC. Sources such as Medline, Embase and the Cochrane Library were systematically searched and all the RCTs comparing curative HR alone to HR plus COSC for HCC were identified. The odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. No treatment-related mortality was reported by the included RCTs and the adverse effects of COSC were generally mild. However, adjuvant COSC did not achieve a statistically significant improvement in the 1-, 3- and 5-year overall survival (OR=1.43, 95% CI: 0.58-3.56, P=0.44; OR=1.39, 95% CI: 0.75-2.55, P=0.29; and OR=1.20, 95% CI: 0.46-3.16, P=0.71, respectively). In addition, adjuvant COSC did not achieve a statistically significant decrease in the incidence of 1-, 3- and 5-year tumor recurrence, with pooled ORs of 0.92 (95% CI: 0.26-1.35, P=0.66); 0.82 (95% CI: 0.66-1.01, P=0.06); and 0.84 (95% CI: 0.71-1.01, P=0.06), respectively. Narrative reviews offer no evidence supporting the use of COSC. Adjuvant COSC has provided marginal benefits for HCC patients following curative HR. Considering the efficacy of sorafenib for advanced HCC and the results of this systematic review, no further trials should be performed to assess the efficacy of adjuvant COSC.

Abstract
Hepatocellular carcinoma (HCC) is associated with poor prognosis and often recurs even after curative hepatic resection (HR) or radiofrequency ablation (RFA). In fact, recurrence is the most frequent cause of postoperative death in patients with HCC; it can arise through intrahepatic metastasis by the primary tumor or through the emergence of de novo tumors. Even though studies have examined numerous adjuvant therapies and chemotherapies for their ability to prevent recurrence, no consensus recommendations exist about their clinical application. To gain a comprehensive picture of clinical options, we identified 39 randomized controlled trials, involving 4113 participants, which explore the efficacy of adjuvant or chemotherapies to prevent HCC recurrence after potentially curative HR or RFA. The available evidence suggests a significant improvement in recurrence-free survival and overall survival when transarterial chemoembolization is used for patients who are at high risk for recurrence, lamivudine for patients with hepatitis B virus (HBV)-related HCC (>500 copies of HBV DNA/ml), and interferon-α for patients with hepatitis C virus (HCV)-infected HCC. In contrast, available evidence does not definitively establish clinical benefits of interferon-β for patients with HCV-related HCC, interferon-α for patients with HBV-related HCC, or any of the following therapies for patients with HCC: iodine-125 brachytherapy, autologous tumor vaccination, adoptive immunotherapy, or therapy involving acyclic retinoid, vitamin K2 analog, iodine-131-labeled lipiodol, sorafenib, heparanase inhibitor PI-88, or capecitabine. Though the findings of our review should be interpreted with caution because of clinical heterogeneity and small sample size in the included trials, they highlight gaps in the evidence base, and therefore, may guide future research.

Abstract
BACKGROUND The high recurrence rate of hepatocellular carcinoma (HCC) after potentially curative treatment determines the long-term prognosis. OBJECTIVE To evaluate the efficacy and safety of adjuvant therapies in patients with HCC who have undergone hepatic resection, transplantation or locoregional ablation therapy. METHODS Several databases were searched to identify randomized controlled trials (RCTs) fulfilling the predefined selection criteria. Meta-analyses were performed to estimate the effects of adjuvant therapies of any modality on recurrence-free survival (RFS) and overall survival (OS). RESULTS Eight adjuvant modalities were identified from 27 eligible RCTs conducted predominantly in Asian populations comparing adjuvant with no adjuvant therapy. Adjuvant chemotherapy, internal radiation and heparanase inhibitor PI-88 therapy failed to improve RFS or OS, while interferon (IFN) therapy yielded significant survival results. The findings of adjuvant vitamin analogue therapy required further examination. Adjuvant adoptive immunotherapy conferred significant benefit for RFS but not for OS. Although cancer vaccine therapy and radioimmunotherapy may improve survival after radical surgery, the results were from single, small-scale trials. Severe side effects were observed in the studies of adjuvant chemotherapy and of IFN therapy. CONCLUSIONS Adjuvant IFN therapy can improve both RFS and OS; however, the benefits of using this agent should be weighed against its side effects. Combination of systemic and transhepatic arterial chemotherapy is not recommended for HCC after potentially curative treatment. Other adjuvant therapies produce limited success for survival. Additional RCTs with proper design are required to establish the role of adjuvant therapies for HCC.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common causes of cancer-related death worldwide. Due to the difficulties of early diagnosis, curative treatments are not available for most patients. Palliative treatments such as chemotherapy are often associated with low response rate, strong adverse effects and limited clinical benefits for patients. The alternative approaches such as fermented wheat germ extract (FWGE) with anti-tumor efficacy may provide improvements in the clinical outcome of current therapy for HCC. This study aimed to clarify antitumor efficacy of FWGE and the combination drug effect of FWGE with chemotherapeutic agents, cisplatin and 5-fluorouracil (5-Fu) in human HCC cells, HepG2, Hep3B, and HepJ5. The present study indicated that FWGE exhibited potential to suppress HepG2, Hep3B, and HepJ5 cells, with the half maximal inhibitory concentrations (IC50) of FWGE were 0.494, 0.371 and 1.524 mg/mL, respectively. FWGE also induced Poly (Adenosine diphosphate ribose) polymerase (PARP) associated cell death in Hep3B cells. Moreover, the FWGE treatment further enhanced the cytotoxicity of cisplatin in all tested HCC cells, and cytotoxicity of 5-Fu in a synergistic manner in HepJ5 cells. Collectively, the results identified the anti-tumor efficacy of FWGE in HCC cells and suggested that FWGE can be used as a supplement to effectively improve the tumor suppression efficiency of cisplatin and 5-Fu in HCC cells.

Abstract
Systemic chemotherapy is the only option for advanced and/or disseminated disease in patients with hepatocellular carcinoma (HCC). For decades, various systemic therapies have been explored for the treatment of advanced HCC. Nevertheless, no satisfactory results have been obtained in cytotoxic chemotherapy so far. However, with the recent introduction of effective chemotherapy agents including sorafenib, the role of systemic therapy for the treatment of HCC is changing. The goals of systemic therapy include prolongation of survival with stabilization of disease progression and, in selected patients, downsizing of primarily unresectable tumors. In the era of effective chemotherapy, patients with advanced HCC should be managed with individualized approaches to optimize outcome.

Abstract
AIMS Numerous postoperative therapies for preventing recurrence of hepatocellular carcinoma (HCC) have been reported, but their efficacy remains controversial and knowledge about adverse effects is limited. A systematic review of randomized controlled trials (RCTs) was performed to gain a comprehensive picture of the efficacy and risks of these therapies. METHODS MEDLINE, EMBASE and the Cochrane Library were systematically searched through July 2011. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated. RESULTS A total of 2989 patients from 28 RCTs involving 10 postoperative therapies were included. For interferon therapy, the estimated RR for the 2-year recurrence rate was 0.84 (95% CI 0.73-0.97, P = 0.02) and the overall survival (OS) was 1.15 (95% CI 1.07-1.22, P < 0.001). Postoperative therapy with the vitamin K2 analog did not lead to a significant reduction in the 1-year recurrence rate, with a pooled RR of 0.60 (95% CI 0.28-1.27, P = 0.18). However, it did slightly improve the 1-year OS, with a pooled RR of 1.03 (95% CI 1.00-1.05, P = 0.03). Transarterial chemotherapy with or without embolization, adoptive immunotherapy and heparanase inhibitor PI-88 therapy may delay tumor recurrence. The effects of acyclic retinoid, lipiodol-iodine-131 and tumor vaccine treatment were promising but require further study. All postoperative therapies except interferon administered intramuscularly were well tolerated by the majority of patients. CONCLUSIONS Use of adjuvant interferon is definitely associated with an increase in OS. Postoperative therapies involving acyclic retinoid, lipidol-iodine-131, or tumor vaccine may improve the OS of patients with HCC after curative treatment.

Abstract
OBJECTIVE The goal of this study is to investigate the effects of sorafenib on tumor growth, recurrence and metastasis after curative resection of liver cancer. RESEARCH METHODS SMMC-7721 and HCCLM3 liver tumors, each with different metastatic potential and basal phosphorylated extracellular signal-regulated kinase (pERK) levels, were orthotopically implanted into 56 nude mice. Mice were divided into a treatment sub study and a prevention sub study. RESULTS In the treatment sub study, tumor volumes in the high pERK-expressing HCCLM3 model were 2.58 ? 0.83 and 0.38 ? 0.09 cm(3) without and with sorafenib, respectively (p < 0.001). The corresponding volumes in the low pERK-expressing SMMC-7721 model were 1.36 ? 0.24 and 0.24 ? 0.14 cm(3) (p < 0.001), respectively. Sorafenib inhibited HCCLM3 cell proliferation and decreased tumor angiogenesis, but did not inhibit proliferation in the SMMC-7721 model. In the prevention sub study, intrahepatic recurrent tumor volumes were 1.96 ? 0.45 and 0.18 ? 0.24 cm(3) (p < 0.001); lung metastasis frequencies were 100 and 0% (p = 0.005); and lifespans were 36 ? 3 and 46 ? 5 days (p = 0.002) in the control and sorafenib subgroups, respectively. CONCLUSIONS Sorafenib inhibits tumor growth and prevents metastatic recurrence after resection of hepatocellular carcinoma in nude mice. The effect of sorafenib does not exclusively depend on high levels of pERK in tumors.

Abstract
BACKGROUND The recurrence of hepatocellular carcinoma is still high even after surgery. Two general recurrence patterns occur: intrahepatic metastasis (IM) and multicentric carcinogenesis (MC). The aim of this study was to investigate the effectiveness of adjuvant chemolipiodolization for reducing IM or MC recurrences after surgery. METHODS A retrospective case-control study was carried out. From April 2005, adjuvant chemolipiodolization was performed in 63 initial hepatocellular carcinoma patients 3 months after surgery. Sixty-four patients who underwent surgery between April 2001 and March 2005 were analyzed as the control group. Recurrence-free and overall survival as well as prognostic factors were analyzed univariately and multivariately. RESULTS The 2-year recurrence-free survival was 57% in the chemolipiodolization group and 37% in the control group (P = 0.02). However, there was no significant difference at 5 years after surgery (P = 0.09). The 5-year overall survival rates in the chemolipiodolization and the control groups were 82.4 and 55.7%, respectively (P = 0.04). Cox proportional multivariate analysis revealed that adjuvant chemolipiodolization was an independent favorable prognostic factor for 2-year recurrence-free survival, and the odds ratio [95% confidential interval] was 0.55 [0.34-0.90] (P = 0.02). However, adjuvant chemolipiodolization was not an independent favorable prognostic factor for 5-year overall survival. CONCLUSIONS Adjuvant chemolipiodolization can reduce the risk of early recurrences, which would be mainly IM derived. However, chemolipiodolization did not reduce late phase recurrences after surgery, which would be mainly MC derived. To prevent late phase recurrences, another novel strategy would be needed.

Clinicopathological determinants of survival after hepatic resection of hepatocellular carcinoma in 97 patients--experience from an Australian hepatobiliary unit. J Gastrointest Surg 2010; 14:1370-80.

Abstract
BACKGROUND Identification of clinicopathological determinants that predict for risk of recurrence and overall survival after undergoing potentially curative hepatic resection for hepatocellular carcinoma is a strategy towards personalizing therapy to improve outcome. Through evaluation of a center's experience with treatment of a disease, determinants unique to the treated patient cohort may be identified. METHODS Ninety-seven patients with hepatocellular carcinoma underwent liver resection. Clinical, treatment, and histopathological variables were collected and evaluated using univariate and multivariate analyses with disease-free survival (DFS) and overall survival (OS) as the endpoints. RESULTS The median follow-up period of 19 (range, 1 to 188) months from the time of hepatic resection. The median DFS and OS after resection of HCC were 17 and 41 months, respectively. Five-year overall survival rate was 45%. Eight independent factors associated with disease-free and overall survival were identified through a multivariate analysis. Three factors: Child-Pugh score (DFS p = 0.045, OS p = 0.001), histopathological grade (DFS p < 0.001, OS p < 0.001), and histological diagnosis of cirrhosis (DFS p < 0.001, OS p < 0.001) predicted for both disease-free and overall survival. CONCLUSION Integrating the knowledge of identified prognostic factors into clinical decision making may provide a clinicopathological signature that could identify patients at greatest risk of treatment failure such that novel interventions may be applied to improve the survival outcome.

Abstract
BACKGROUND Postoperative recurrence of hepatocellular carcinoma (HCC) is a major problem after surgical resection. To date, adjuvant chemotherapy or other adjuvant modalities have not been proven effective in preventing or delaying recurrence. The aim of this prospective randomized study was to evaluate the effectiveness of capecitabine as a postoperative adjuvant regimen in inhibiting the recurrence of HCC. MATERIALS AND METHODS Between August 2003 and January 2005, 60 HCC patients who underwent curative resection were randomized into a capecitabine (n = 30) or a control (n = 30) group. The capecitabine group received 4-6 episodes of capecitabine treatment plus routine supportive care. Each episode consisted of 2 weeks of capecitabine followed by 1-week rest. The control group received routine supportive care only. The follow-up was 4-65 months (median: 47.5 months). RESULTS Cancer recurred in 16 patients (53.3%) in the capecitabine group and in 23 patients (76.7%) in the control group. The median time to recurrence (TTR) was 40.0 months (95% confidence interval [95% CI], 31.0-49.2 months) and 20.0 months (95% CI, 12.8-27.2 months) in the capecitabine and control groups, respectively (P = 0.046). The 5-year overall survival rate was 62.5% and 39.8% in the capecitabine group and control group, respectively (P = .216). Adverse reactions to capecitabine were generally mild and included nausea, vomiting, diarrhea, and decreased white blood cell and/or platelet counts. CONCLUSION Postoperative adjuvant therapy with capecitabine is well tolerated, postpones the recurrence of HCC, and reduces the risk of tumor recurrence. In addition, it is likely to improve postoperative survival.

Abstract
BACKGROUND This study aimed to clarify risk factors for early recurrence and examine the subsequent outcome in patients undergoing potentially R0 resection of small hepatocellular carcinomas (HCCs) (<or=2 cm in greatest dimension). METHODS Eighty-nine patients were divided into 2 groups as follows: 26 patients suffering from recurrence within 2 years of surgery (early recurrence group) and 63 patients who were disease-free for at least 2 years (disease-free 2Y group). RESULTS Only 7 of 63 patients (11%) from the group that was disease-free for at least 2 years died during the 5-year period after surgery, whereas 13 of 26 patients (50%) from the early recurrence group died. Multivariate analysis showed that the preoperative maximum removal rate of technetium-99m-diethylenetriamine pentaacetic acid-galactosyl human serum albumin and microscopic vascular invasion were independent predictors of the early recurrence of small HCC. CONCLUSIONS Early recurrence of small HCC is the leading cause of death within 5 years after R0 resection. The preoperative hepatic functional reserve influences early recurrence, even in patients with small tumors.

Abstract
BACKGROUND Hepatocellular carcinoma is a disease of great concern. Surgery is the treatment of choice, but there is still a high recurrence rate after resection. OBJECTIVES To determine the benefits and harms of neoadjuvant and adjuvant therapies compared to surgery alone or surgery and placebo/supportive therapy after curative resection for operable hepatocellular carcinoma. SEARCH STRATEGY We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, Science Citation Index Expanded, Chinese Biomedical Database, and US National Cancer Institute's Physician's Data Query Trials Database until 2005. References of the identified trials were also searched for identifying further trials. SELECTION CRITERIA Randomised and quasi-randomised trials that compared hepatocellular carcinoma patients who were given and not given neoadjuvant/adjuvant therapy as a supplement to curative liver resection. DATA COLLECTION AND ANALYSIS Data were extracted independently by two authors and discrepancies resolved by consensus. The survival and disease-free survival curves were compared using their one, two, three, four, and five-year survival rates, median survival times, and the result of the significance tests (P-values). MAIN RESULTS A total of 12 randomised trials were identified, totaling 843 patients. The size of the randomised clinical trials ranged from 30 to 155 patients. Both preoperative (neoadjuvant) and postoperative (adjuvant), systemic and locoregional (+/- embolisation), chemo- and immunotherapy interventions were tested. Treatment regimens and patients selected were not comparable, so no pooling was done. Only one regimen using preoperative transcatheter arterial chemoembolisation with doxorubicin was similar in two trials. Four of the twelve trials reported survival benefit at five years when given adjuvant or neoadjuvant therapy. Disease-free survival was reported in nine trials, and the estimated hazard ratios show that disease-free survival was significant in two trials at five years. These two trials had not shown a survival advantage, but the recurrence was significantly lower in patients given adjuvant or neoadjuvant therapy. The highest toxicity rate was in a trial using oral 1-hexylcarbamoyl 5-fluorouracil which resulted in 12 out of 38 patients being withdrawn from the trial because of adverse events. AUTHORS' CONCLUSIONS There is no clear evidence for efficacy of any of the adjuvant and neo-adjuvant protocols reviewed, but there is some evidence to suggest that adjuvant therapy may be beneficial offering prolonged disease-free survival. In order to detect a realistic treatment advantage, larger trials with lower risk of systematic error will have to be conducted.

Abstract
Hepatocellular carcinoma often recurs even after curative resection. Although some encouraging data showing improvements in recurrence-free times have been reported with the use of intraarterial 131I-lipiodol infusion, retinoids, interferon, or immunotherapy after hepatectomy, there is no consensus regarding standard adjuvant therapy for resectable hepatocellular carcinoma. A novel target agent, sorafenib, which has recently become a standard of care for advanced disease, may also be promising in an adjuvant setting to prevent early recurrence after curative surgery. In future trials, it will be important to identify appropriate target populations for each type of adjuvant approach; that is, an agent with definitive antitumor activity for high-risk patients, and one that shows chemoprevention for low-risk patients.

Abstract
New advancements have emerged in the field of hepatocellular carcinoma (HCC) in recent years. There has been a switch in the type of presentation of HCC in developed countries, with a clear increase of tumors <2 cm in diameter as a result of the wide implementation of surveillance programs. Non-invasive radiological techniques have been developed and validated for the diagnosis of small and tiny HCCs. Simultaneously, diagnostic criteria based on molecular profiling of early tumors have been proposed. The current clinical classification of HCC divides patients into 5 stages with a specific treatment-oriented schedule. There is no established molecular classification of HCC, although preliminary proposals have already been published. Advancements in the treatment arena have come from well designed trials. Radiofrequency ablation is currently consolidated as providing better local control of the disease compared with percutaneous ethanol injection. New devices are available to improve the anti-tumoral efficacy of conventional chemoembolization. Sorafenib, a multikinase inhibitor, has shown survival benefits in patients at advanced stages of the disease. This advancement represents a breakthrough in the management of this complex disease, and proves that molecular targeted therapies can be effective in this otherwise chemo-resistant tumor. Consequently, sorafenib will become the standard of care in advanced cases, and the control arm for future trials. Now, the research effort faces other areas of unmet need, such as the adjuvant setting of resection/local ablation and combination therapies.

Abstract
Hepatocellular cancer is the third leading cause of cancer-related deaths worldwide. Its incidence has increased dramatically in the United States because of the spread of hepatitis C virus infection and is expected to increase for the next 2 decades. Hepatitis B virus, hepatitis C virus, and chronic heavy alcohol use leading to cirrhosis of the liver remain the most important causes. The diagnosis of hepatocellular cancer rests on a combination of radiologic, serologic, and histopathologic criteria. Liver transplantation is the only definitive treatment. Resection of the tumor and other percutaneous therapies are more commonly used in practice, because most hepatocellular cancers are detected at an advanced stage. Patients who are at high risk for the development of hepatocellular cancer should be screened with an ultrasound of the liver every 6 months. The prognosis is dependent on both the underlying liver function and the stage at which the tumor is diagnosed. The aim of this review is to familiarize internists in screening, diagnosis, and referral of patients with hepatocellular cancer in an appropriate and timely fashion.

Abstract
Frequent recurrence of hepatocellular carcinoma (HCC) after surgery remains a major clinical problem. This randomized controlled trial evaluated whether postoperative adjuvant therapy with oral uracil-tegafur (UFT) prevents recurrence of HCC. A total of 160 patients who underwent curative hepatic resection for HCC were randomly assigned to receive either 300 mg/day of UFT for 1 year after surgery (n = 79, UFT group) or surgery alone (n = 80, control group). The primary endpoint was recurrence-free survival, and the secondary endpoint was overall survival. Other study variables included liver function and type of recurrence. During a median follow-up of 4.8 years (range: 0.5-7.9), recurrence-free survival curves in the groups were similar (P = .87). Overall survival was slightly but not significantly worse in the UFT group than in the control group (P = .08). The rates of recurrence-free and overall survival at 5 years were 29% and 58%, respectively, in the UFT group, as compared with 29% and 73%, respectively, in the control group. The hazard ratio for recurrence in the UFT group, relative to the control, was 1.01 (95% confidence interval: 0.84-1.22, P = .87). The proportion of patients with advanced recurrence (i.e., multiple, extrahepatic, or associated with vascular invasion) was significantly higher in the UFT group (74%, 43 of 58 patients with recurrence) than in the control group (53%, 30 of 57) (P = .02). In conclusion, our results offer no evidence to support potential benefits of adjuvant chemotherapy with UFT after surgery in patients with HCC and suggest that such treatment may even worsen overall survival.

Abstract
For the minority of patients with hepatocellular carcinoma (HCC), surgical or locally ablative therapies may offer the prospect of cure. However, the majority of patients present with advanced disease such that treatment with curative intent is no longer possible. For some of these patients, with good hepatic reserve and a patent portal venous system, chemoembolisation may afford a modest survival benefit. The remainder of patients are frequently treated with systemic therapies with palliative intent. This review aims to summarise the current systemic treatment approaches for HCC in the adjuvant and palliative setting before reviewing the evidence for novel therapies emerging in this field. At present there are a number of interesting therapeutic agents with potential activity in HCC. The challenge now is the design of clinical trials to optimally evaluate these agents.

Abstract
AIM: To investigate the clinicopathological risk factors for immediate post-operative fatal recurrence of hepatocellular carcinoma (HCC), which may have practical implication and contribute to establishing high risk patients for pre- or post-operative preventive measures against HCC recurrence.
METHODS: From June 1994 to May 2004, 269 patients who received curative resection for HCC were reviewed. Of these patients, those who demonstrated diffuse intra-hepatic or multiple systemic recurrent lesions within 6 mo after surgery were investigated (fatal recurrence group). The remaining patients were designated as the control group, and the two groups were compared for clinicopathologic risk factors.
RESULTS: Among the 269 patients reviewed, 30 patients were enrolled in the fatal recurrence group. Among the latter, 20 patients showed diffuse intra-hepatic recurrence type and 10 showed multiple systemic recurrence type. Multivariate analysis between the fatal recurrence group and control group showed that pre-operative serum alpha-fetoprotein (AFP) level was greater than 1 000 μg/L ( P= 0.02; odds ratio = 2.98), tumor size greater than 6.5 cm (P = 0.03; OR = 2.98), and presence of microvascular invasion (P = 0.01; OR = 4.89) were the risk factors in the fatal recurrence group. The 48.1% of the patients who had all the three risk factors and the 22% of those who had two risk factors experienced fatal recurrence within 6 mo after surgery.
CONCLUSION: Three distinct risk factors for immediate post-operative fatal recurrence of HCC after curative resection are pre-operative serum AFP level > 1 000 μg/L, tumor size > 6.5 cm, and microvascular invasion. The high risk patients with two or more risk factors should be the candidates for various adjuvant clinical trials.

Abstract
Abstract
Background
Orthotopic liver transplantation (OLT) plays a pivotal role in the management of selected patients with initial hepatocellular carcinoma (HCC). After disappointing early results and a shortage of cadaveric grafts, patients are currently selected for OLT on the basis of tumour size and number. Limitations of these criteria and the advent of living donation have prompted their re-evaluation. The principal aims of this review were to define the limitations of current transplant criteria for HCC, and to identify potential areas for improvement.
Methods
A Medline search using the terms ‘liver transplantation’ and ‘hepatocellular carcinoma’ was conducted. Additional references were sourced from key articles.
Results and conclusion
In patients with HCC, biological properties of the tumour are more accurate than radiological criteria in determining outcome after transplantation. Despite the risks of tumour biopsy, which may have been previously overstated, histological evaluation before transplantation may have a role and warrants further study. By expanding the donor pool and eliminating waiting times, live donor liver transplantation is a valuable resource that has yet to fulfil its potential because of unresolved ethical issues concerning the safety of the donor. The availability of long-term outcome data may help to clarify this in the near future.
