Chen JL, Chen YS, Ker CG. Network meta-analysis of the prognosis of curative treatment strategies for recurrent hepatocellular carcinoma after hepatectomy. World J Gastrointest Surg 2023; 15:258-272. [PMID: 36896302 PMCID: PMC9988642 DOI: 10.4240/wjgs.v15.i2.258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 11/28/2022] [Accepted: 01/16/2023] [Indexed: 02/27/2023] Open
Abstract
BACKGROUND Recurrent hepatocellular carcinoma (rHCC) is a common outcome after curative treatment. Retreatment for rHCC is recommended, but no guidelines exist.
AIM To compare curative treatments such as repeated hepatectomy (RH), radiofrequency ablation (RFA), transarterial chemoembolization (TACE) and liver transplantation (LT) for patients with rHCC after primary hepatectomy by conducting a network meta-analysis (NMA).
METHODS From 2011 to 2021, 30 articles involving patients with rHCC after primary liver resection were retrieved for this NMA. The Q test was used to assess heterogeneity among studies, and Egger’s test was used to assess publication bias. The efficacy of rHCC treatment was assessed using disease-free survival (DFS) and overall survival (OS).
RESULTS From 30 articles, a total of 17, 11, 8, and 12 arms of RH, RFA, TACE, and LT subgroups were collected for analysis. Forest plot analysis revealed that the LT subgroup had a better cumulative DFS and 1-year OS than the RH subgroup, with an odds ratio (OR) of 0.96 (95%CI: 0.31-2.96). However, the RH subgroup had a better 3-year and 5-year OS compared to the LT, RFA, and TACE subgroups. Hierarchic step diagram of different subgroups measured by the Wald test yielded the same results as the forest plot analysis. LT had a better 1-year OS (OR: 1.04, 95%CI: 0.34-03.20), and LT was inferior to RH in 3-year OS (OR: 10.61, 95%CI: 0.21-1.73) and 5-year OS (OR: 0.95, 95%CI: 0.39-2.34). According to the predictive P score evaluation, the LT subgroup had a better DFS, and RH had the best OS. However, meta-regression analysis revealed that LT had a better DFS (P < 0.001) as well as 3-year OS (P = 0.881) and 5-year OS (P = 0.188). The differences in superiority between DFS and OS were due to the different testing methods used.
CONCLUSION According to this NMA, RH and LT had better DFS and OS for rHCC than RFA and TACE. However, treatment strategies should be determined by the recurrent tumor characteristics, the patient’s general health status, and the care program at each institution.

Abstract
BACKGROUND/AIM Transient receptor potential vanilloid 6 (TRPV6), an endothelial Ca2+-selective entry channel, is expressed in various cancer types, and a selective TRPV6 inhibitor is currently being investigated in a clinical trial. However, TRPV6 expression in hepatocellular carcinoma (HCC) has not been reported. MATERIALS AND METHODS We evaluated TRPV6 expression in 219 cases of HCC and analyzed its association with clinicopathological parameters and prognostic significance. TRPV6 mRNA expression was compared between HCC and non-tumor liver tissues using various public datasets, and its prognostic effect was examined in The Cancer Genome Atlas (TCGA) cohort. RESULTS Low TRPV6 expression was found in 37.4% of patients, which was significantly associated with adverse histologic features, and patients with low TRPV6 expression had shorter recurrence-free and disease-free survival. TRPV6 mRNA expression was consistently lower in HCC compared to non-tumor liver samples in public datasets, at the whole tissue level as well as single-cell level. Patients with low TRPV6 expression in the TCGA cohort had shorter progression-free survival. CONCLUSION TRPV6 expression is down-regulated in HCCs and associated with a poor prognosis. TRPV6 may be a prognostic biomarker in HCC.

Front Oncol 2022; 12:816472. [PMID: 35186751 PMCID: PMC8848276 DOI: 10.3389/fonc.2022.816472] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Accepted: 01/11/2022] [Indexed: 12/11/2022] Open
Abstract
Background Non-B, non-C hepatocellular carcinoma (NBNC-HCC) may be related to metabolic syndrome, and the incidence of this tumor type is increasing annually. The definition of metabolic-associated fatty liver disease (MAFLD) proposed in 2020 may help to more accuratelyassess the association between metabolic syndrome and NBNC-HCC. However, this new concept has not yet been applied in NBNC-HCC research. Therefore, this study aimed to compare the clinicopathological characteristics of patients with NBNC-HCC and CHB-HCC diagnosed between 2009-13 and 2014-18, focusing on metabolic risk factors and the new concept of MAFLD. Method Patients with BCLC-0/A-HCC who received curative hepatectomy between January 2009 and December 2018 were retrospectively assessed; the associations between clinicopathological characteristics and clinical outcomes of NBNC-HCC and CHB-HCC were analyzed by multivariate analysis. Result Compared to patients diagnosed in 2009-13, the frequency of metabolic disorders in NBNC-HCC was significantly higher in 2014-18 [DM (p=0.049), HTN (p=0.004), BMI (p=0.017) and MAFLD (p=0.003)]; there was no significant change in patients with CHB-HCC. Moreover, CHB-HCC was an independent risk factor for HCC recurrence (HR, 1.339; 95% CI, 1.010-1.775, p=0.043) and death (HR, 1.700; 95% CI, 1.017-2.842, p=0.043) compared to NBNC-HCC. Conclusions Therisk of MAFLD, obesity, DM, and hypertension in patients with early-stage NBNC have significantly increased in recent years, thus metabolic syndrome should be monitored in this special population. Moreover, NBNC-HCC tend to had a better prognosis than CHB-HCC, probably due to their distinct clinicopathological features.

Long-term outcome of percutaneous radiofrequency ablation for periportal hepatocellular carcinoma: tumor recurrence or progression, survival and clinical significance. Cancer Imaging 2022; 22:2. [PMID: 34983650 PMCID: PMC8725335 DOI: 10.1186/s40644-021-00442-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Accepted: 12/08/2021] [Indexed: 02/08/2023] Open
Abstract
Background/aim Recent studies have suggested that periportal location of percutaneous radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is considered as one of the independent risk factors for local tumor progression (LTP). However, the long-term therapeutic outcomes of percutaneous RFA as the first-line therapy for single periportal HCCand corresponding impacts on tumor recurrence or progression are still unclear. Materials and methods From February 2011 to October 2020, a total of 233 patients with single nodular HCC ≤ 5 cm who underwent RFA ± transarterial chemoembolization (TACE) as first-line therapy was enrolled and analyzed, including 56 patients in the periportal group and 177 patients in the nonperiportal group. The long-term therapeutic outcomes between the two groups were compared, risk factors of tumor recurrence or progression were evaluated. Results The LTP rates at 1, 3, and 5 years were significantly higher in the periportal group than those in the nonperiportal group (15.7, 33.7, and 46.9% vs 6.0, 15.7, and 28.7%, respectively, P = 0.0067). The 1-, 3- and 5-year overall survival (OS) rates in the periportal group were significantly worse than those in the nonperiportal group (81.3, 65.1 and 42.9% vs 99.3, 90.4 and 78.1%, respectively, P<0.0001). In the subgroup of single HCC ≤ 3 cm, patients with periportal HCC showed significantly worse LTP P = 0.0006) and OS (P<0.0001) after RFA than patients with single nonperiportal HCC; The univariate and multivariate analyses revealed that tumor size, periportal HCC and AFP ≥ 400ug/ml were independent prognostic factors for tumor progression after RFA. Furthermore, patients with single periportal HCC had significantly higher risk for IDR(P = 0.0012), PVTT(P<0.0001) and extrahepatic recurrence(P = 0.0010) after RFA than those patients with single nonperiportal HCC. . Conclusion The long-term therapeutic outcomes of RFA as the first-line therapy for single periportal HCC were worse than those for single nonperiportal HCC, an increased higher risk of tumor recurrence or progression after RFA was significantly associated with periportal HCC.

Immunological Markers, Prognostic Factors and Challenges Following Curative Treatments for Hepatocellular Carcinoma. Int J Mol Sci 2021; 22:ijms221910271. [PMID: 34638613 PMCID: PMC8508906 DOI: 10.3390/ijms221910271] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 09/20/2021] [Accepted: 09/21/2021] [Indexed: 01/27/2023] Open
Abstract
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortalities worldwide. Patients with early-stage HCC are eligible for curative treatments, such as surgical resection, liver transplantation (LT) and percutaneous ablation. Although curative treatments provide excellent long-term survival, almost 70–80% of patients experience HCC recurrence after curative treatments. Tumor-related factors, including tumor size, number and differentiation, and underlying liver disease, are well-known risk factors for recurrence following curative therapies. Moreover, the tumor microenvironment (TME) also plays a key role in the recurrence of HCC. Many immunosuppressive mechanisms, such as an increase in regulatory T cells and myeloid-derived suppressor cells with a decrease in cytotoxic T cells, are implicated in HCC recurrence. These suppressive TMEs are also modulated by several factors and pathways, including mammalian target of rapamycin signaling, vascular endothelial growth factor, programmed cell death protein 1 and its ligand 1. Based on these mechanisms and the promising results of immune checkpoint blockers (ICBs) in advanced HCC, there have been several ongoing adjuvant studies using a single or combination of ICB following curative treatments in HCC. In this review, we strive to provide biologic and immunological markers, prognostic factors, and challenges associated with clinical outcomes after curative treatments, including resection, LT and ablation.

Abstract
INTRODUCTION In spite of the high frequency of recurrence of hepatocellular carcinoma (HCC) after resection, little evidence exists to directly help to plan a reasonable schedule for the frequency and intensity of postoperative surveillance for recurrence. METHODS 1,918 consecutive patients with Child-Turcott-Pugh class A who had T1- or T2-staged HCCs detected by active surveillance and underwent curative resection for their tumors at 3 teaching hospitals in Korea, followed by recurrence screening at 6-monthly or shorter intervals. To set an evidence-based timetable for postoperative surveillance, we investigated the annual hazard rate of recurrence through postoperative year 10 in patients undergoing hepatectomy for HCC, and the clinical and morphological phenotypes associated with early versus late recurrence. RESULTS The estimated hazard rate for recurrence peaked during year 0-1 (21.7%), with a subsequent gradual decrease through 5 years, followed by stabilization at <7.0% until year 10, except in the case of cirrhotics, who had a rate of 10.5% during year 4-5. Multivariate time-to-recurrence analysis by recurrence period revealed that serum alpha-fetoprotein ≥200 ng/mL, larger size of tumor, tumor multiplicity, microvascular invasion, capsular invasion, and higher METAVIR fibrosis stage were significantly related to disease recurrence within 5 years after resection, while cirrhosis (METAVIR F4) alone was related to disease recurrence beyond 5 years (Ps < 0.05). Post-relapse overall survival was better in the latter group (p = 0.033). CONCLUSIONS Our chronological and morphological insights into recurrence after resection of primary HCCs may help implement an optimal intensity of surveillance for recurrence.

Abstract
BACKGROUND/AIM Pregnancy up-regulated non-ubiquitous calmodulin kinase (PNCK) is a member of calmodulin kinase, and overexpression of PNCK with involvement in carcinogenesis have been reported in HER-2 amplified breast cancer, clear cell renal cell carcinoma and nasopharygeal carcinoma. However, the expression of PNCK and its clinical implication have not been elucidated in hepatocellular carcinoma (HCC). MATERIALS AND METHODS We investigated PNCK expression at both the protein and mRNA level using immunohistochemistry (IHC) and microarray gene expression profiling in HCC tissue samples, and evaluated its association with clinicopathological parameters and their potential prognostic significance. RESULTS High PNCK protein expression and high PNCK mRNA level was observed in 61.7% and 34.7% of total HCC cases, respectively. PNCK mRNA level was higher in tumor tissues than in background non-tumor tissues, and significantly correlated with protein expression by IHC. High PNCK expression was associated with higher Edmondson grade, intrahepatic metastasis, microvascular invasion and higher AFP levels. Patients with high PNCK expression showed shorter recurrence-free survival and disease-specific survival, and high mRNA expression of PNCK was an independent prognostic factor in disease-specific survival. CONCLUSION Up-regulation of PNCK expression as well as its association with poor prognosis was demonstrated in HCC. PNCK might be a prognostic biomarker of HCC, and could be a potential candidate therapeutic target.

Extrapolating Prognostic Factors of Primary Curative Resection to Postresection Recurrences Hepatocellular Carcinoma Treatable by Radiofrequency Ablation. Gastroenterol Res Pract 2021; 2021:8878417. [PMID: 33488700 PMCID: PMC7801068 DOI: 10.1155/2021/8878417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Revised: 12/13/2020] [Accepted: 12/16/2020] [Indexed: 11/23/2022] Open
Abstract
Objective Recurrence after curative resection for hepatocellular carcinoma (HCC) is a major cause of death from this disease. Factors of primary curative resection are available and potential in the prognosis of follow-up treatment. Our aim was to assess the prognostic significance of primary curative resection factors in recurrent HCC patients undergoing radiofrequency ablation therapy (RFA). Methods In this retrospective study, we assessed 235 patients who underwent limited RFA of HCC recurrences (tumors ≤ 5 cm; nodules ≤ 3) after primary curative resection. Factors of primary curative resection were collected, and overall survival and recurrence-free survival were evaluated by the Kaplan-Meier method. Univariate and multivariate analyses were used to identify significant prognostic factors. Results After a median follow-up of 36 months, 54 patients died, and 128 patients had hepatic recurrence. On univariate analyses, patients whose primary tumors were less differentiated (p = 0.032 and p = 0.048) and required less time to recur (p = 0.013 and p = 0.001) after curative resection displayed poorer overall survival and higher recurrence rates following RFA. On multivariate analyses, the pathologic tumor grade (p = 0.026 and p = 0.038) and recurrence-free survival after primary curative resection (p = 0.028 and p < 0.001) emerged as independent risk factors of survival and HCC recurrence. Conclusions Primary tumor differentiation and time to recurrence after curative resection are viable prognostic factors of overall survival and further recurrence risk in patients undergoing RFA of recurrent HCC.

Abstract
BACKGROUND The effects of direct-acting antivirals (DAAs) on survival and recurrence rates after curative hepatocellular carcinoma (HCC) treatment in patients with hepatitis C virus (HCV) infection remain controversial. METHODS This retrospective, multicenter study involved Child-Pugh class A patients within the Milan criteria who had a first diagnosis of HCC and survived 6 months or longer after undergoing hepatectomy or radiofrequency ablation (RFA). The DAA-treated group (DAA group) included 56 patients, and the DAA-untreated group (untreated group) included 261 patients. The study was conducted using the propensity score-matched (1:2) DAA group and untreated group, 56 and 112 patients, respectively. RESULTS The survival rate at 48 months in the DAA group and the untreated group was 91.0% and 68.7%, respectively, showing significantly better survival in the DAA group (HR: 0.33; 95% CI 0.13-0.84; p = 0.021). The recurrence rate at 48 months was 36.7% and 66.7%, respectively, showing a significantly lower recurrence rate in the DAA group (HR, 0.46; 95% CI 0.27-0.77; p = 0.003). The median albumin-bilirubin (ALBI) score at 3 years post-HCC treatment was - 2.84 in the DAA group and - 2.34 in the untreated group. The ALBI score showed a significant improvement from baseline to 3 years post-HCC treatment (p = 0.001), whereas that in the untreated group showed a significant decline (p = 0.040). CONCLUSIONS DAAs after HCC treatment prevents deterioration of hepatic functional reserve and significantly improves both recurrence and survival rates.

Abstract
AIM The impact of sustained virologic response (SVR) on surgical outcomes for patients with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) remains controversial. This study aimed to evaluate the influence of SVR on long-term surgical outcomes after hepatectomy. METHODS This multicenter study included 504 patients who underwent curative resection for HCV-related HCC. Patients with a history of HCC treatment, HBV infection, poor liver function, and tumor with major vascular invasion were excluded. Long-term surgical outcomes (overall survival [OS] and recurrence-free survival [RFS]) among patients who achieved SVR before hepatectomy (Pre-SVR group: 58 patients), after hepatectomy (Post-SVR group: 54 patients), and without SVR (Non-SVR group: 186 patients) were compared after adjusting for 13 confounding factors. Using the surgically resected specimens, comparison of the pathological changes in liver fibrosis between the first and second hepatectomy were analyzed. RESULTS Patients with SVR were younger, had better liver function, and less liver fibrosis compared to patients without SVR. Propensity score-matched OS and RFS were significantly better in Pre-SVR group than Non-SVR group (P = .029 and P = .009, respectively). Inverse probability-weighted OS and RFS were also significantly better in the Post-SVR group (P = .001 and P = .021, respectively) than in the Non-SVR group. Histopathological evaluation revealed that only the patients with SVR had regression of liver fibrosis (P < .05). CONCLUSION Achievement of SVR before or after hepatectomy is essential for improving long-term surgical outcomes in patients with HCV-related HCC.

Clin Mol Hepatol 2020; 26:516-528. [PMID: 32911589 PMCID: PMC7641570 DOI: 10.3350/cmh.2020.0016] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2020] [Accepted: 05/21/2020] [Indexed: 02/06/2023] Open
Abstract
Background/Aims Although hepatocellular carcinoma (HCC) is notorious for its high recurrence rate, some patients do not experience recurrence for more than 5 years after resection or radiofrequency ablation for early-stage HCC. For those with five recurrence-free period, the risk of HCC recurrence within the next 5 years remains unknown. Methods A total of 1,451 consecutive patients (median, 55 years old; males, 79.0%; hepatitis B virus-related, 79.3%) with good liver function (Child-Pugh class A) diagnosed with early-stage HCC by Barcelona Clinic Liver Cancer Staging and received radiofrequency ablation or resection as an initial treatment between 2005 and 2010 were analyzed. Results During a median follow-up period of 8.1 years, 961 patients (66.2%) experienced HCC recurrence. The cumulative recurrence rates increased to 39.7%, 60.3%, and 71.0% at 2, 5, and 10 years, respectively, and did not reach a plateau. Five years after HCC diagnosis, 487 patients were alive without experiencing a recurrence. Among them, during a median of 3.9 additional years of follow-up (range, 0.1–9.0 years), 127 patients (26.1%) experienced recurrence. The next 5-year cumulative recurrence rate (5–10 years from initial diagnosis) was 27.0%. Male sex, higher fibrosis-4 scores, and alpha-fetoprotein levels at 5 years were associated with later HCC recurrence among patients who did not experience recurrence for more than 5 years. Conclusions The HCC recurrence rate following 5 recurrence-free years after HCC treatment was high, indicating that HCC patients warrant continued HCC surveillance, even after 5 recurrence-free years.

Abstract
Background To date, no standard follow-up guidelines exist regarding patients receiving ablation for initial recurrent hepatocellular carcinoma (HCC). We aimed to explore whether intensive follow-up could benefit these patients. Methods We reviewed the clinical data of patients who received complete ablation for initial HCC recurrence after curative treatments in our institution from January 2005 to June 2017. Risk factors for second recurrence of HCC were identified by univariate and multivariate analyses. Patients were classified into low- and high-risk groups according to the outcome of the classification and regression model. The patients were further categorized into short- (< 3 months) and long-interval (3–6 months) follow-up subgroups based on their surveillance in the first 2 years after complete ablation for initial recurrence. The Kaplan-Meier method with log-rank test was performed to compare the overall survival (OS) based on follow-up intervals in each risk group. We also validated our results by stratifying patients into subgroups with different numbers of risk factors and comparing the OS between patients with different follow-up intervals. Results A total of 361 patients were enrolled. The risk factors for secondary recurrence included the Barcelona Clinic Liver Cancer (BCLC) stage at initial recurrence and first recurrence-free survival after curative treatments for primary HCC (p < 0.001 and p = 0.002). Two risk groups (low and high) were identified. In both the low- and high-risk groups, the OS of patients was not associated with intervals of follow-up (p = 0.29 and 0.49). No significant difference was found in the rates of BCLC 0/A stage, tumor location or curative treatments for the second recurrence by different follow-up intervals in each risk group (p = 0.34 and 0.87; p = 0.69 and 0.97). The same tendency was found in subgroups with 0/1/2 risk factors for secondary recurrence during validation. Conclusion The long-interval follow-up did not compromise the survival of patients with complete ablation for initial recurrent HCC.

Peptide vaccine as an adjuvant therapy for glypican-3-positive hepatocellular carcinoma induces peptide-specific CTLs and improves long prognosis. Cancer Sci 2020; 111:2747-2759. [PMID: 32449239 PMCID: PMC7419030 DOI: 10.1111/cas.14497] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 05/12/2020] [Accepted: 05/14/2020] [Indexed: 12/20/2022] Open
Abstract
There is no established postoperative adjuvant therapy for hepatocellular carcinoma (HCC), and improvement of patient prognosis has been limited. We conducted long‐term monitoring of patients within a phase II trial that targeted a cancer antigen, glypican‐3 (GPC3), specifically expressed in HCC. We sought to determine if the GPC3 peptide vaccine was an effective adjuvant therapy by monitoring disease‐free survival and overall survival. We also tracked GPC3 immunohistochemical (IHC) staining, CTL induction, and postoperative plasma GPC3 for a patient group that was administered the vaccine (n = 35) and an unvaccinated patient group that underwent surgery only (n = 33). The 1‐y recurrence rate after surgery was reduced by approximately 15%, and the 5‐y and 8‐y survival rates were improved by approximately 10% and 30%, respectively, in the vaccinated group compared with the unvaccinated group. Patients who were positive for GPC3 IHC staining were more likely to have induced CTLs, and 60% survived beyond 5 y. Vaccine efficacy had a positive relationship with plasma concentration of GPC3; high concentrations increased the 5‐y survival rate to 75%. We thus expect GPC3 vaccination in patients with HCC, who are positive for GPC3 IHC staining and/or plasma GPC3 to induce CTL and have significantly improved long‐term prognosis.

Retrospective analysis of sorafenib efficacy and safety in Chinese patients with high recurrence rate of post-hepatic carcinectomy. Onco Targets Ther 2019; 12:5779-5791. [PMID: 31410023 PMCID: PMC6643495 DOI: 10.2147/ott.s168447] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2018] [Accepted: 01/17/2019] [Indexed: 02/05/2023] Open
Abstract
Background: There is no guideline recommendation for preventing hepatocellular carcinoma (HCC) recurrence after hepatic resection. Moreover, an unmet need exists on the effectiveness of sorafenib therapy in recurrent HCC. Purpose: We therefore assessed the efficacy and safety of sorafenib in Chinese HCC patients with high risk of recurrence. Patients and methods: Data were collected retrospectively from 15 Chinese research centers from January 1, 2012 to November 15, 2013, by chart reviews of patients with moderate-advanced HCC who received hepatic carcinectomy. The primary end point was recurrence-free survival rate at 1 year in patients with a high recurrence risk. Secondary end points included 1-year survival rate, time to recurrence and safety assessment. Results: A total of 209 high-risk patients (sorafenib, n=98; control, n=111) who underwent carcinectomy were analyzed. There was no significant difference in the proportion of patients with recurrence-free survival at 1 year between the sorafenib and control (70.43% vs 68.90%: χ2=0.007, P=0.934). One-year survival rate was significantly higher with sorafenib than observed with control (95.5% vs 83.35%; χ2=7.441, P=0.006). Time to recurrence between sorafenib and control groups was similar. Incidences of all the adverse events (AEs) were similar in both the groups and transaminase elevation was most common in both groups (20.37% vs 24.79%). Thrombocytopenia incidence was significantly lower with the sorafenib group than with control (1.85% vs 9.40%; P=0.015). Conclusion: Sorafenib may be considered as a feasible option in the treatment of HCC recurrence.

The tumor diameter cut-off for predicting microscopic intrahepatic metastasis of hepatocellular carcinoma patients without treatment history differs from that of hepatocellular carcinoma patients with a treatment history. Clin Transl Oncol 2019; 22:319-329.

Abstract
BACKGROUND AND AIM Intrahepatic metastasis (IM) of hepatocellular carcinoma (HCC) occurs via vascular invasion; the tumor diameter that affects the risk of micro intra-hepatic metastasis (MIM) should be larger than that which affects the risk of micro vessel invasion (MVI). The aim of the present study was to determine the optimum tumor diameter cut-off value for predicting the presence of MIM in HCC patients without treatment history and HCC patients with a treatment history and to compare these diameters between cases of MVI and MIM. METHODS This retrospective study included 621 patients without macroscopic vessel invasion or intrahepatic metastasis on preoperative imaging who underwent hepatectomy. The cut-off tumor diameter for predicting the presence of MIM was determined by a receiver operating characteristic curves analysis. RESULTS The optimum cut-off value for predicting the presence of MIM in HCC patients without treatment history was 43 mm. In contrast, the optimum cut-off value for predicting the presence of MIM in HCC patients with a treatment history was 20 mm. Among 46 HCC patients with MIM without treatment history, there were 20 patients with MIM without MVI who were considered to have potential multi-centric (MC) tumors rather than IM. The cumulative overall survival rates in patients with MIM without MVI (potential MC) was significantly better than that in patients with both MIM and MVI (P = 0.022). CONCLUSIONS The tumor diameter cut-off value for predicting MIM differed between HCC patients without treatment history and with a treatment history and slightly smaller than those for predicting MVI beyond our expectation.

Abstract
Background/Aims Guidelines recommend surveillance for hepatocellular carcinoma (HCC) recurrence at 3-month intervals during the first year after curative treatment and 6-month intervals thereafter in all patients. This strategy does not reflect individual risk of recurrence. We aimed to stratify risk of recurrence to optimize surveillance intervals 1 year after treatment. Methods We retrospectively analyzed 1,316 HCC patients treated with resection/radiofrequency ablation at Barcelona Clinic Liver Cancer stage 0/ A. In patients without 1-year recurrence under 3-monthly surveillance, a new model for recurrence was developed using backward elimination methods: training (n=582)/ validation cohorts (n=291). Overall survival (OS) according to risk stratified by the new model was compared according to surveillance intervals: 3-monthly versus 6-monthly (n=401) after lead time bias correction and propensity-score matching analyses. Results Among patients without 1-year recurrence, age and international normalized ratio values were significant factors for recurrence (hazard ratio [HR], 1.03; 95% confidence interval [CI], 1.00 to 1.03; p=0.009 and HR, 5.63; 95% CI, 2.24 to 14.18; p<0.001; respectively). High-risk patients stratified by the new model showed significantly higher recurrence rates than low-risk patients in the validation cohort (HR, 1.73; 95% CI, 1.18 to 2.53; p=0.005). After propensity-score matching between the 3-monthly and 6-monthly surveillance groups, OS in high-risk patients under 3-monthly surveillance was significantly higher than that under 6-monthly surveillance (p=0.04); however, OS in low-risk patients under 3-monthly surveillance was not significantly different from that under 6-monthly surveillance (p=0.17). Conclusions In high-risk patients, 3-monthly surveillance can prolong survival compared to 6-monthly surveillance. However, in low-risk patients, 3-monthly surveillance might not be beneficial for survival compared to 6-monthly surveillance.

Abstract
AIMS The aim of our systematic review was to compare the efficacy of salvage liver transplantation (SLT) versus curative locoregional therapy (CLRT) for patients with recurrent hepatocellular carcinoma (HCC). METHODS Studies comparing the SLT with CLRT for patients with recurrent HCC were selected from database of PubMed, EMBASE, and Cochrane library. The outcomes including overall survival, disease-free survival, and complications were abstracted. Individual and pooled odds ratio (OR) with 95% confidence interval of each outcome was analyzed. RESULTS Seven retrospective studies involving 840 patients were included. There is no difference between SLT and CLRT group regarding the1- and 3-year overall survival rates. However, the 5-year overall survival and 1-, 3-, 5-year disease-free survival were significantly higher after SLT than after CLRT (OR = 1.62, 95% CI 1.09-2.39, P = .02; OR = 4.08, 95% CI 1.95-8.54, P = .0002; OR = 3.63, 95% CI 2.21-5.95, P <.00001; OR = 5.71, 95% CI 2.63-12.42, P <.0001, respectively). But CLRT was associated with fewer complications and shorter hospital-stay compared with SLT. For SLT compared with repeat hepatectomy (RH), the subgroup analysis indicated that SLT group had a significantly higher 3- and 5-years disease-free survival than the RH group (OR = 3.23, 95% CI 1.45-7.20, P = .004; OR = 4.79, 95% CI 1.88-12.25, P = .001, respectively). CONCLUSION The efficacy of SLT may be superior to that of CLRT in the treatment of recurrent HCC. However, considering the similar overall survival rate and current situation of donor shortage, RH is still an important option for recurrence HCC.

Abstract
AIM This study aimed to evaluate the efficacy of percutaneous thermal ablation combined with transarterial embolization for recurrent hepatocellular carcinoma after hepatectomy and establish a prognostic nomogram to predict survival. METHODS One hundred seventeen patients with recurrent hepatocellular carcinoma receiving ablation from 2009 to 2014 were included in primary cohort to establish a prognostic nomogram. Between 2014 and 2016, 51 patients with recurrent hepatocellular carcinoma treated by ablation were enrolled in the validation cohort to validate the predictive accuracy of the nomogram. All patients underwent locoregional ablation. Overall survival was the primary end point, and progression-free survival was the second end point. The performance of the nomogram was assessed through concordance index and calibration curve and compared with 5 conventional hepatocellular carcinoma staging systems. RESULTS The 1-, 3-, and 5-year overall survival rates of primary cohort were 88.4%, 70.7%, and 64.1%, respectively. The 1-, 3-, and 5-year progression-free survival rates of primary cohort were 44%, 14%, and 8.7%, respectively. The results of multivariate analysis showed that tumor size ( P = .0469; hazard ratio, 1.020; 95% confidence interval, 1.0004-1.040), preoperative extrahepatic disease ( P = .0675; hazard ratio, 2.604; 95% confidence interval, 0.933-7.264), and close to hepatic hilum <2 cm ( P = .0053; hazard ratio, 3.691; 95% confidence interval, 1.474-9.240) were predictive factors for overall survival. The study established a nomogram to predict survival (concordance index, 0.752; 95% confidence interval, 0.656-0.849). According to the predicted overall survival, patients with recurrent hepatocellular carcinoma were divided into 3 risk classes ( P < .05): low-risk group (total score <55; predicted 5-year overall survival rate, 82.9%), intermediate-risk group (55 ≤ total score < 99; predicted 5-year overall survival rate, 52.8%), and high-risk group (hazard ratio, total score ≥99; predicted 5-year overall survival rate, not available). CONCLUSION Percutaneous thermal ablation appears to be an effective procedure for the treatment of recurrent hepatocellular carcinoma after hepatectomy. The proposed nomogram provides a mechanism to accurately predict survival and could stratify risk among patients with recurrent hepatocellular carcinoma treated by ablation therapy.

Contrast-Enhanced Ultrasound to Monitor Early Recurrence of Primary Hepatocellular Carcinoma after Curative Treatment. BIOMED RESEARCH INTERNATIONAL 2018; 2018:8910562. [PMID: 30533441 PMCID: PMC6247733 DOI: 10.1155/2018/8910562] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Accepted: 10/18/2018] [Indexed: 01/27/2023]
Abstract
Objective To evaluate contrast-enhanced ultrasound (CEUS) for monitoring early intrahepatic recurrence of primary hepatocellular carcinoma (HCC) after curative treatment. Methods We prospectively analyzed 97 patients (124 nodules) with primary HCC who underwent hepatic resection or radiofrequency ablation and subsequently experienced intrahepatic recurrence. Patients were assessed with conventional ultrasound and CEUS. They were also assessed with contrast-enhanced computed tomography (CECT) and/or magnetic resonance imaging (MRI). The image characteristics of CEUS of recurrent hepatocellular carcinoma and high-grade dysplastic nodules (HGDNs) were analyzed. In addition, the ability of CEUS and CECT/MRI to assess internal artery vascularization in recurrent disease was compared. Results CEUS of recurrent hepatocellular carcinoma showed hyperenhancement in the arterial phase in 96 of 99 nodules, and it showed hypo- or isoenhancement for portal venous and delayed phases. The most common enhancement patterns were “fast-in and slow-out” and “fast-in and fast-out”. Based on the arterial hyperenhancement of lesions and with clinical data such as patient history of HCC and increased level of serum alpha-fetoprotein, the diagnostic accuracy of CEUS for recurrent HCC was significantly higher than that based on the enhancement pattern of “fast-in and fast-out”. CEUS of HGDNs showed local or global hyperenhancement during the arterial phase, isoenhancement during the portal venous phase, and isoenhancement or slight hypoenhancement during the delayed phase. The enhancement pattern was “fast-in and slow-out”. In some cases, it was difficult to differentiate HGDNs from recurrent disease using CEUS. Vascularization in recurrent disease was significantly higher when assessed by CEUS than when assessed with CECT/MRI (P < 0.05). For detecting recurrent disease, CEUS showed sensitivity of 97.0%, specificity of 68.0%, positive predictive value of 92.3%, and negative predictive value of 85.0%. The corresponding parameters for CECT/MRI were 71.7%, 72.0%, 88.8%, and 39.1%. Conclusion Intrahepatic recurrent HCC and HGDNs with diameter ≤ 3.0 cm have a characteristic appearance on CEUS. This imaging modality may be effective for monitoring early intrahepatic recurrence after curative treatment of primary HCC.

Abstract
The aim of the present study was to evaluate the role of hepatectomy plus adjuvant transcatheter arterial chemoembolization (TACE) in patients with multicentric occurrence (MO) or intrahepatic metastases (IM) of hepatocellular carcinoma (HCC). Patients with multifocal HCC who underwent hepatic resection only (HR) or HR plus adjuvant TACE (HRT) between January 2005 and December 2015 were divided into MO or IM groups. The patient characteristics and outcomes were retrospectively analyzed. A total of 103 patients (59 and 44 in the MO and IM groups, respectively) were included in the analysis. The 1-, 3- and 5-year overall survival (OS) rates were 92.7, 76.8 and 56.8% for the MO group, and 93.1, 41.6 and 18.5% for the IM group, respectively (OS, P=0.001), and the 1-, 3- and 5-year disease-free survival (DFS) rates were 84.1, 44.6 and 40.5% for the MO group and 51.7, 22.5 and 15.0% for the IM group, respectively (DFS, P<0.001). In the subgroup analysis, the overall survival were significantly better in the MO-HRT group compared with those in the MO-HR group (P=0.019), which was also observed between the IM-HRT and IM-HR groups (P=0.132). Furthermore, the 1-, 3- and 5-year OS demonstrated non-significant differences between patients with <3 and ≥3 tumors in the MO-HR group (P=0.300), but significantly reduced OS for patients with ≥3 tumors in the IM-HR group compared with that for patients with <3 tumors (P=0.132). In conclusion, surgical resection combined with adjuvant TACE may result in significantly increased survival rates of patients with MO-HCC. Tumor number should not be an absolute contradiction to hepatectomy in patients with MO-HCC.

Abstract
Objective We investigated the possible factors for predicting the future progression to hepatocellular carcinoma (HCC) from hypovascular nodules detected in the hepatobiliary phase of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-MRI). Methods A total of 91 hypovascular nodules detected by Gd-EOB-DTPA-MRI in 28 patients without any past history of treatment for HCC were retrospectively examined. The nodules were categorized into those with and without HCC progression, then comparisons were made to identify any factors possibly related to a progression to HCC in each case. In addition, we performed a receiver operating characteristics (ROC) analysis to determine the cut-off value for the initial nodule size for predicting HCC progression within 12 months. Results The observation period of the 28 patients was 1,172.6±95.6 (mean±standard error) days. The number of hypovascular nodules that changed to hypervascular ones was 15 (16.5%), and the cumulative incidence of hypervascular transformation was 7.1% at 12 months and 12.7% at 24 months. Of all 91 hypovascular nodules, 33 in 18 patients were diagnosed as HCC based on hypervascular transformation and/or size enlargement, while the remaining 58 did not progress to HCC. There was no significant difference regarding the background characteristics between the HCC progressed and non-progressed groups according to a multivariate analysis, or between the patients who had nodules that progressed to HCC and those with nodules that did not progress to HCC. Regarding HCC progression at 12 months, the area under the ROC (AUROC) had a level of 0.745 and showed that an initial nodule cut-off size of 9.5 mm (sensitivity, 57.9%; specificity, 87.3%) was predictive. Conclusion In patients without a past HCC treatment history, it is difficult to determine whether hypovascular nodules have a high risk of progression to HCC based on background factors alone.

Abstract
It is unclear whether targeted agents can produce survival advantage in patients with advanced HCC previously treated with sorafenib. We performed this meta-analysis of randomized trials and reviewed clinical outcomes of molecular targeted agents in the second-line treatment for advanced HCC. A systematic computerized search of the electronic databases PubMed, Embase, Google Scholar, and Cochrane Library (up to May 2017) was carried out. From six studies, 2,388 patients were included in the meta-analysis. Almost all patients were treated with sorafenib as first-line therapy. Compared with placebo, targeted agents significantly improved time-to-progression (hazard ratio = 0.62, 95% confidence interval: 0.49-0.78, P < 0.0001). In terms of overall survival, targeted therapy tended to improve prognosis (hazard ratio = 0.86, 95% confidence interval: 0.74-1.01, P = 0.06). In conclusion, this meta-analysis indicates that molecular targeted agents have a potential to improve prognosis after failure of first-line treatment with sorafenib in patients with advanced HCC.

Abstract
The overexpression of c-Met protein has been detected in hepatocellular carcinoma (HCC). However, its prognostic impact remains uncertain. We performed this meta-analysis to evaluate the prognostic value of c-Met overexpression in patients who underwent curative surgical resection for HCC. A systematic computerized search of the electronic databases was carried out. From 5 studies, 1,408 patients who underwent surgical resection for HCC were included in the meta-analysis. Compared with patients with HCC having low c-Met expression, patients with c-Met-high tumor showed significantly worse relapse-free survival (hazard ratio = 1.26 [95% confidence interval, 1.02–1.56], P = 0.03) and overall survival (hazard ratio = 1.16 [95% confidence interval, 1.03–1.31], P = 0.01). In conclusion, our meta-analysis indicates that c-Met overexpression is a significant adverse prognostic factor for recurrence and survival in patients who underwent surgical resection for HCC.

Abstract
Background/Aims Nicotinamide adenine dinucleotide phosphate oxidase (NOX)-mediated reactive oxygen species contribute to various liver diseases, including hepatocellular carcinoma (HCC). Uncertainties remain regarding the prognostic relevance of NOX1 and NOX4 protein expression in HCC. Methods NOX1 and NOX4 protein expression was examined by using immunohistochemistry in tumor tissue from 227 HCC patients who underwent hepatectomy. Results High immunoreactivity for NOX1 was observed in 197 (86.8%) of the 227 HCC cases and low immunoreactivity for NOX4 in 112 (49.3%). NOX1 and NOX4 proteins had opposite prognostic effects. High NOX1 expression was an independent predictor of both shorter recurrence-free survival (RFS) (p<0.01) and shorter overall survival (OS) (p=0.01). Low NOX4 expression was an independent predictor of both shorter RFS (p<0.01) and shorter OS (p=0.01). Subgroup analysis showed that, among patients with normal α-fetoprotein levels, patients with tumor size ≤5.0 cm and patients in Barcelona Clinic Liver Cancer stage A, high NOX1 expression had unfavorable effects on RFS, whereas low NOX4 expression had unfavorable effects on both RFS and OS. Conclusions These findings demonstrated that NOX1 and NOX4 protein expression had opposite prognostic effects for HCC patients. Moreover, both proteins had prognostic value in HCC patients with normal α-fetoprotein levels or with early-stage HCC.

Abstract
The long-term prognosis following resection of hepatocellular carcinoma (HCC) remains unsatisfactory as a result of a high incidence of recurrence. Prevention of recurrence is the most important strategy to improve the long-term survival results. The role of hepatectomy itself, as an accelerator of carcinogenesis, has not been adequately evaluated in HCC patients. Studies in animal models have revealed a link between liver regeneration under chronic inflammation and hepatic tumorigenesis. Inhibiting different signal transduction pathways during liver regeneration without compromising the ability of the liver to regenerate appears to be a rational strategy and may decrease HCC development and recurrence. If this hypothesis is proven using animal models, this strategy could be evaluated in future clinical trials in humans.

Abstract
The present study reveals an immunological characterization of circulating and tumor-infiltrating T follicular helper cells (Tfh), namely CXCR5+CD45RA−CD4+ T cells, and their related cytokines in hepatitis B virus-related hepatocellular carcinoma (HCC) patients. In HCC patients, circulating Tfh cells showed a CCR7+ and/or ICOS+ phenotype with increased Th2-like cells and decreased Th1-like and Th17-like subsets. Although the bulk frequency of circulating Tfh cells was not altered in HCC patients, the frequency of infiltrated CXCR5+CD45RA−CD4+ CD3+cells was higher in tumor than in para-tumor tissues, and Th1-like cells were the predominant phenotype. Circulating Tfh cells in HCC patients were defective in the production of IL-21 in vitro, which was in accordance with lower IL-21 levels in tumor tissues than in para-tumor tissues. Serum CXCL13 was increased in HCC patients and associated with recurrence-free survival after hepatectomy. This was confirmed in an additional HCC cohort of 111 patients with up to 5 years follow-up. Immunohistochemical staining indicated that the percentage of CXCR5+ or CXCL13+ cells was higher in poorly differentiated than in well-differentiated tumors. In conclusion, patients with HBV-related HCC showed altered phenotypes and impaired function of Tfh cells or subpopulations. CXCL13 could be a potential biomarker for predicting recurrence in HCC patients after hepatectomy.

Abstract
When assessing outcome in hepatocellular carcinoma (HCC), it is important to consider prognostic factors in background non-tumorous liver tissue as well as in the tumor, since multiple occurrence is associated with background liver status such as hepatitis. The current study aimed to elucidate molecular prognostic predictors that have an association with HCC background non-tumorous tissue. Microarray expression profiling identified aldo-keto reductase family 1, member B10 (AKR1B10) as a putative non-tumorous prognostic factor, and AKR1B10 gene expression was investigated in 158 curatively resected HCC cases by reverse transcription-quantitative polymerase chain reaction. AKR1B10 expression (AKR1B10 value/GAPDH value × 1,000) was significantly higher in tumor tissue (median, 9.2200; range, 0.0003-611.0200; n=158) than in the corresponding non-tumorous tissue (median, 0.5461; range, 0.0018-69.0300; n=158) (P<0.001). When the samples were grouped according to AKR1B10 expression in tumor tissue relative to non-tumorous tissue, tumor<non-tumorous expression (n=26) significantly correlated with poor recurrence-free survival (P=0.0074) and overall survival (OS) (P<0.0001), and was an independent prognostic factor for OS (P=0.0011) in a multivariate analysis. The ratio of AKR1B10 messenger RNA levels in HCC and corresponding non-tumorous tissues may predict prognosis after curative hepatectomy, with low expression in HCC tissue relative to non-tumorous tissue indicative of poor prognosis.

Abstract
PURPOSE The aim of this study was to define the capsules of synchronous multicentric small hepatocellular carcinomas (HCCs) with use of high-frequency intraoperative ultrasonography (IOUS). METHODS Among the 131 consecutive patients undergoing hepatic resection and high-frequency IOUS for HCC, 16 synchronous multicentric small HCCs in 13 patients were histologically diagnosed in the resected specimens. High-frequency IOUS and pathologic findings of these lesions were compared, with particular focus on the presence and appearance of the capsule in or around each lesion. RESULTS Synchronous multicentric small HCCs were pathologically classified into distinctly nodular (n=12) or vaguely nodular (n=4) types. All 12 distinctly nodular HCCs including six subcentimeter lesions showed detectable capsules on high-frequency IOUS and pathology. The capsules appeared as a hypoechoic rim containing hyperechoic foci (n=6), hypoechoic rim (n=5), or hyperechoic rim (n=1) with varying degrees of coverage around each lesion. Histologically, the capsules were composed of a combination of one to four layers consisting of a fibrous capsule, peritumoral fibrosis, prominent small vessels, and entrapped hepatic parenchyma. CONCLUSION Synchronous multicentric small HCCs with distinctly nodular type, even at subcentimeter size, can show capsules with varying coverage and diverse echogenicity on high-frequency IOUS.

Abstract
The long-term prognosis after resection of hepatocellular carcinoma (HCC), which is one of the treatment options for early-stage HCC, remains unsatisfactory as a result of a high incidence of disease recurrence. Recent studies performed in murine models revealed a link between liver regeneration under chronic inflammation and hepatic tumorigenesis. Sorafenib is a potent drug for advanced HCC with multikinase inhibition activity. We propose that inhibition of signal transduction pathways which are activated during hepatectomy, using Sorafenib, will reduce accelerated tumorigenesis. To test this hypothesis, we studied the Mdr2-knockout (KO) mouse strain, a model of inflammation-associated cancer, which underwent partial hepatectomy (PHx) at three months of age, with or without Sorafenib.Here we show that Sorafenib treatment during PHx inhibited different signal transduction pathways at the multikinase levels, but did not result in increased morbidity or mortality. At the early stages after PHx, Sorafenib treatment had no effect on the course of proliferation, apoptosis and DNA repair in the regenerating liver, but resulted in decreased stellate cells activation and inflammatory response. Finally, we show that Sorafenib treatment during PHx at three months of age resulted in decreased fibrosis and tumor formation at 8.5 months.In conclusion our study indicates that short-term Sorafenib treatment during PHx is safe and effective in inhibiting inflammation-associated cancer, and is therefore a potential strategy for recurrence prevention in patients with early-stage HCC treated with PHx.

Abstract
The recurrence rates of Hepatocellular carcinoma (HCC) are high, necessitating novel and effective adjuvant therapies. Therefore, we conducted a phase II study of glypican-3 (GPC3) peptide vaccine as an adjuvant therapy for HCC patients. Forty-one patients with initial HCC who had undergone surgery or radiofrequency ablation (RFA) were analyzed in this phase II, open-label, single-arm trial. Ten vaccinations were performed for 1 y after curative treatment. We also investigated case-control subjects, where selected patients treated surgically during the same period were analyzed. The expression of GPC3 in the available primary tumors was determined by immunohistochemical analysis. Six patients received RFA therapy while 35 received surgery. The recurrence rate tended to be lower in the 35 patients treated with surgery plus vaccination compared to 33 patients who underwent surgery alone (28.6% vs. 54.3% and 39.4% vs. 54.5% at 1 and 2 y, respectively; p = 0.346, 0.983). Twenty-five patients treated with surgery and vaccination had GPC3-positive tumors; the recurrence rate in this group was significantly lower compared to that in 21 GPC3-positive patients who received surgery only (24% vs. 48% and 52.4% vs. 61.9% at 1 and 2 y, respectively; p = 0.047, 0.387). The GPC3 peptide vaccine improved the 1-y recurrence rate in patients with GPC3-positive tumors. This study demonstrated that GPC3 expression by the primary tumor may be used as a biomarker in a putative larger randomized clinical trial to determine the efficacy of the GPC3-derived peptide vaccine.

Abstract
OBJECTIVES The efficacy of the all-oral administration of daclatasvir and asunaprevir for 24 weeks was compared with that of telaprevir for 12 weeks plus pegylated interferon and ribavirin (PEG-IFN/RBV) for 24 weeks, and that of simeprevir for 12 weeks plus PEG-IFN/RBV for 24 weeks, with a focus on the prevention of occurrence and recurrence of hepatocellular carcinoma (HCC). The levels of alanine aminotransferase (ALT) and α-fetoprotein (AFP) as suppressive markers of HCC were also measured. METHODS Patients received daclatasvir and asunaprevir (n = 17), simeprevir plus PEG-IFN/RBV (n = 15) and telaprevir plus PEG-IFN/RBV (n = 25). Sustained virological response (SVR) and the mean change in the level of serum ALT, AFP and platelet (PLT) count were compared among the three groups. RESULTS No difference in SVR was observed in patients given daclatasvir with asunaprevir (SVR4), telaprevir plus PEG-IFN/RBV or simeprevir plus PEG-IFN/RBV (SVR24). Also, no significant difference was observed in the mean change of serum ALT, AFP or PLT count among the three groups. CONCLUSION The preventive effect of the IFN-free, all-oral regimen of daclatasvir and asunaprevir was observed with a focus on the occurrence and recurrence of HCC, as was IFN-based treatment with telaprevir or simeprevir plus PEG-IFN/RBV.

Semiannual Imaging Surveillance Is Associated with Better Survival in Patients with Non-B, Non-C Hepatocellular Carcinoma. Mediators Inflamm 2015; 2015:687484.

Abstract
Since it remains elusive whether and how the imaging surveillance affects the survival in patients with non-B, non-C hepatocellular carcinoma (NBNC-HCC), we conducted this retrospective study which investigated the association between the semiannual surveillance prior to HCC diagnosis and the survival in patients with the initial diagnosis of HCC induced by hepatitis B virus (HBV) and/or hepatitis C virus (HCV) infections (N = 141) and non-B, non-C etiology (N = 30). It was demonstrated that surveillance was less frequently performed in the NBNC-HCC patients compared to that in HCC patients with HBV and/or HCV infections (B/C-HCC patients), and the survival was unfavorable in NBNC-HCC patients. On the other hand, the survival of NBNC-HCC patients with semiannual surveillance was significantly favorable than those patients without semiannual surveillance, and the survival was similar between B/C-HCCs and NBNC-HCCs with semiannual surveillance. In conclusion, though NBNC-HCC patients compared to B/C-HCC patients had poorer prognosis overall, these NBNC-HCC patients with semiannual surveillance had a better survival almost equivalent to the survival of B/C-HCC patients with semiannual surveillance, demonstrating the clinical utility of the semiannual imaging surveillance program for NBNC-HCCs.

Abstract
Purpose Cell division cycle and apoptosis regulator 1 (CCAR1) plays a dynamic role in regulation of cell growth and apoptosis by serving as a cofactor of steroid/thyroid nuclear receptors, β-catenin, and p53 in a variety of cell types including different cancer cells. However, whether CCAR1 protein is overexpressed in hepatocellular carcinoma (HCC) and the prognostic significance of CCAR1 protein expression in HCC have not been reported. Materials and Methods In 167 HCC patients with long-term follow-up, CCAR1 protein expression was examined by immunohistochemistry. Results High CCAR1 protein expression was observed in 149 of the 167 HCC cases (89.2%) and showed significant correlation with microvascular invasion, intrahepatic metastasis, higher American Joint Committee on Cancer (AJCC) T stage, and early recurrence. High CCAR1 expression showed an unfavorable effect on recurrence-free survival (RFS) (p=0.002). In subgroup analysis, among patients with α-fetoprotein ≤ 20 ng/mL (n=54) and patients with AJCC T stage 1 (n=62), significant differences in RFS were observed between high CCAR1 expression groups and low CCAR1 expression groups (p=0.015 and p=0.004, respectively). High CCAR1 expression tended to be an independent predictor of shorter RFS (p=0.054) and showed an unfavorable effect on overall survival (OS) (p=0.015). In subgroup analysis, among patients with α-fetoprotein ≤ 20 ng/mL (n=54), significant difference in OS was observed between high CCAR1 expression group and low CCAR1 expression group (p=0.046). Conclusion CCAR1 protein could be a potential biomarker predicting RFS in HCC patients after curative hepatectomy. In addition, CCAR1 had prognostic values in HCC patients with normal serum α-fetoprotein levels or early stage HCC.

Abstract
Hepatocellular carcinoma (HCC), which is a common malignancy worldwide, usually develops in a cirrhotic liver due to hepatitis virus infection. Metabolic syndrome, which is frequently complicated by obesity and diabetes mellitus, is also a critical risk factor for liver carcinogenesis. Green tea catechins (GTCs) may possess potent anticancer and chemopreventive properties for a number of different malignancies, including liver cancer. Antioxidant and anti-inflammatory activities are key mechanisms through which GTCs prevent the development of neoplasms, and they also exert cancer chemopreventive effects by modulating several signaling transduction and metabolic pathways. Furthermore, GTCs are considered to be useful for the prevention of obesity- and metabolic syndrome-related carcinogenesis by improving metabolic disorders. Several interventional trials in humans have shown that GTCs may ameliorate metabolic abnormalities and prevent the development of precancerous lesions. The purpose of this article is to review the key mechanisms by which GTCs exert chemopreventive effects in liver carcinogenesis, focusing especially on their ability to inhibit receptor tyrosine kinases and improve metabolic abnormalities. We also review the evidence for GTCs acting to prevent metabolic syndrome-associated liver carcinogenesis.

Abstract
Purpose Cancer cells frequently express genes that are specifically or preferentially expressed in male germ cells under normal conditions. The ATPase family AAA domain-containing 2 (ATAD2) is one such and works as an important cofactor for MYC-dependent transcription. In hepatocellular carcinoma (HCC), ATAD2 has been identified as a candidate driver gene located within the amplified 8q24 locus. However, the prognostic significance of ATAD2 protein expression in HCC remains uncertain. Materials and Methods We investigated ATAD2 protein expression by immunohistochemistry in tumor tissue from 182 HCC patients who underwent curative resection. Associations of ATAD2 expression with clinicopathologic variables or prognosis of HCC patients were analyzed. Results ATAD2 expression was observed in 119 (65.4%) of the 182 HCCs and tended to be independent predictor of early recurrence (p=0.059). ATAD2 expression showed an unfavorable influence on recurrence-free survival (RFS) (p < 0.001). Subgroup analysis among patients with tumor size ≤ 5.0 cm (n=109), patients at Barcelona Clinic Liver Cancer stage 0 or A (n=92), and patients with α-fetoprotein ≤ 20 ng/mL (n=61), the ATAD2-positive groups unfavorably influenced RFS (p=0.008, p=0.009, and p=0.013, respectively). In addition, ATAD2 expression was an independent predictor of shorter RFS (p=0.002). ATAD2 expression showed an unfavorable influence on disease-specific survival (p=0.001), but was not an independent predictor of shorter disease-specific survival (p=0.109). Conclusion ATAD2 protein expression may be a potential predictor of RFS in HCC patients after curative resection and ATAD2 may have prognostic value in patients with early stage HCC or normal serum α-fetoprotein level.

In hepatocellular carcinoma (HCC), PEG10 has been identified as a potential target gene located within the amplified 7q21 locus. The purpose of this study was to investigate the expression of PEG10 protein in HCC and evaluate its prognostic significance. Materials and Methods PEG10 protein expression was examined by immunohistochemistry in tumor tissues from 218 HCC patients undergoing curative resection. Furthermore, the relationships between PEG10 expression and clinicopathologic features or postoperative survival of HCC patients were evaluated. The median follow-up period was 119.8 months for survivors. Results PEG10 expression was observed in 148 of the 218 HCCs (67.9%) and was significantly correlated with younger age, female, higher Edmondson grade, microvascular invasion, intrahepatic metastasis, higher American Joint Committee on Cancer T-stage, and higher α-fetoprotein level. PEG10 expression was an independent predictor of early recurrence (p=0.013), and it showed an unfavorable influence on recurrence-free survival (p < 0.001). A subgroup analysis showed that among patients with α-fetoprotein ≤ 20 ng/mL (80 patients), the PEG10-positive group also showed an unfavorable influence on recurrence-free survival (p=0.002). Moreover, a multivariate survival analysis identified PEG10 as an independent predictor of shorter recurrence-free survival (p=0.005). PEG10 expression showed an unfavorable influence on overall survival (p=0.007) but was not an independent predictor of shorter overall survival (p=0.128). Conclusion PEG10 protein could be a potential biomarker predicting early recurrence and recurrence-free survival in HCC patients after curative resection, even in those with normal serum α-fetoprotein levels.

Abstract
Liver cancer is the fifth most common cancer, but the second leading cause of cancer death, in the world, with more than 700,000 fatalities annually. The major etiology of liver cancer is infection with an hepatotropic virus such as hepatitis B virus or hepatitis C virus infection. While chronic viral infection remains the main cause of liver disease and risk of hepatocellular carcinoma (HCC), rates of nonviral-associated HCC are occurring at an alarmingly increasing rate. Like many cancers, survival rates are closely associated with time of detection. If HCC is caught early, survival rates can be as high as 50%. Regrettably, most cases of HCC are caught late where survival rates can be as low as 2-7%. Thus, there has been great interest in discovering serum biomarkers that could be used to identify those with HCC. To this end, many groups have examined the N-linked glycans to identify changes that occur with HCC. As the liver secretes the vast majority of proteins into the serum, this has often been a starting point for study. In serum, alterations in core fucosylation, outer-arm fucosylation, increased sialylation, and glycan branching have been observed in patients with HCC. Similar findings have been found directly in HCC tissue suggesting that these glycan changes may play a role in tumor formation and development.

The Importance of Lamivudine Therapy in Liver Cirrhosis Patients Related HBV with Advanced Hepatocellular Carcinoma Receiving Hepatic Arterial Infusion Chemotherapy. ACTA ACUST UNITED AC 2015; 2:112-118. [PMID: 27595062 PMCID: PMC4997933 DOI: 10.2174/2212697x02666150602220735] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2014] [Revised: 04/08/2015] [Accepted: 06/02/2015] [Indexed: 01/11/2023]
Abstract
Purpose: We have previously reported that continuous hepatic arterial infusion chemotherapy (HAIC) might be more effective for advanced hepatocellular carcinoma (aHCC) in patients with liver cirrhosis (LC) related to HCV infection (C-LC) or alcohol abuse (A-LC) than in patients who had LC related to HBV infection (B-LC). The aim of the present study was to retrospectively assess the efficacy of lamivudine therapy for B-LC patients with aHCC undergoing HAIC. Methods: Seventeen adult Japanese B-LC patients with aHCC were treated by HAIC with or without lamivudine (100 mg/day) between 2002 and 2008 at our hospital. Their tumors were inoperable according to computed tomography findings. HAIC (LV at 12 mg/hr, CDDP at 10 mg/hr, and 5-FU at 250 mg/22 hr) was given via the proper hepatic artery every 5 days for 4 weeks using a catheter connected to a subcutaneously implanted drug delivery system. Results: Nine of the 17 patients received lamivudine at a dose of 100 mg/day together with HAIC (LAM group), while 8 patients did not receive lamivudine and only had HAIC (non-LAM group). The response rate was 12.5 in the non-LAM group and 0.0% in the LAM group. However, the survival of the LAM group was better than that of the non-LAM group, although there was no significant difference between them. The median survival time of the LAM and non-LAM groups was 310 and 157 days, respectively. HBV-DNA levels were significantly lower after chemotherapy compared with that before chemotherapy in the LAM group. In the non-LAM group, the percentage of Th2 cells before HAIC and after HAIC was significantly higher than in the control group. However, the percentage of Th2 cells in the LAM group after HAIC was not different from that in the control group, although it was significantly higher in the LAM group than in the control group before chemotherapy. Conclusions: These results indicate that lamivudine therapy may prolong the survival of B-LC patients receiving HAIC for aHCC by reducing HBV-DNA level and inhibiting the increase of Th2 cells in host immunity.

[PMID: 25596083 DOI: 10.1007/s13277-014-3031-5] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2014] [Accepted: 12/30/2014] [Indexed: 12/22/2022] Open
Abstract
The prognosis of hepatocellular carcinoma (HCC) treated by radiofrequency ablation (RFA) is mainly associated with tumor recurrence. So far, no tissue biomarker of recurrence has been confirmed in biopsy specimens. Previous studies have reported that aberrant expression of microRNA-34a (miR-34a) is involved in oncogenesis and progression of HCC. The aim of this study was to investigate the prognostic value of tissue miR-34a expression in patients with HCC treated with RFA. Patients with early-stage single-nodule HCC treated with RFA were included, and tissue expression of miR-34a were assessed by quantitative reverse-transcription polymerase chain reaction. Main clinical endpoints were overall and early recurrence. The Kaplan-Meier method was used to plot recurrence curves and univariable and multivariable Cox regression analyses were performed to assess independent predictive factors for recurrence. Of 120 patients, recurrence occurred in 67 patients (55.8 %) with a median follow-up of 31 months. Forty-one patients (34.2 %) recurred within 2 years after RFA. The median miR-34a level was 0.87 (range 0.06-21.54). Low miR-34a level was associated with larger tumor size (P = 0.033) and higher serum alpha-fetoprotein (AFP) level (P = 0.004). When analyzed with a Cox regression model, the two independent predictive factors for overall recurrence were high serum AFP level (hazard ratio [HR] = 1.21; 95 % confidence interval [CI] = 1.04-1.36; P = 0.039) and low miR-34a level (HR = 1.44; 95 % CI = 1.13-1.72; P = 0.011). The expression of miR-34a was also an independent predictive factor for early recurrence (HR = 1.49; 95 % CI = 1.15-1.79; P = 0.008). Taken together, this study suggests that the expression of miR-34a in HCC biopsy specimens has an independent predictive value of early recurrence after RFA.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide. In laboratory animal models, diethylnitrosamine (DENA) is a well-known agent that has a potent hepatocarcinogenic effect that is used to induce HCC. As curcumin has a potent anti-inflammatory effect with strong therapeutic potential against a variety of cancers, our present study aims to investigate its curative effects and the possible mechanisms of action against DENA-induced HCC in male rats. Investigation of biochemical and molecular parameters of HCC animal model liver showed an overexpression of TGF-β and Akt proteins accompanied with a significant reduction of the proapoptotic marker caspase-3. DENA-induced hepatic cellular injury resulted also in a significant increase in liver function marker enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lipid peroxides in this group. Curcumin treatment partially reversed DENA-induced damage as it reduced the overexpression of the angiogenic and anti-apoptotic factors TGF-β and Akt and improved caspase-3 expression. Also, it could partially normalize the serum values of liver marker enzymes and lipid peroxidation and improve liver architecture. Curcumin shows a unique chemotherapeutic effect in reversing DENA-induced HCC in rat model. This effect is possibly mediated through its proapoptotic, antioxidant, anti-angiogenic, as well as antimitotic effects. It interferes and modulates cell signaling pathways and hence turns death signals and apoptosis on within tumor cells.

Abstract
OBJECTIVES To identify the incidence and risk factors that predict local tumour progression (LTP) after ultrasound-guided percutaneous microwave ablation (MWA) of liver malignancies. MATERIALS AND METHODS One thousand two hundred and nine patients with 2,529 malignant nodules (mean size 2.8 ± 1.4 cm, range 0.9-8.0 cm) were treated by MWA between July 2005 and December 2012. The influence of 11 factors on the risk of LTP was assessed. Univariate Kaplan-Meier and Cox proportional hazard models were used for statistical analysis. RESULTS The overall LTP was 4.2 % per tumour and 8.6 % per patient with a median follow-up of 20.3 months. LTP per tumour was 4.3 % for primary liver cancer and 4.1 % for metastases (p = 0.32). The survival of LTP and free-LTP patients at 1, 3, and 5 years was 92.4 %, 71.6 %, and 45.1 %, respectively, and 92.9 %, 70.1 %, and 52.4 %, respectively (p = 0.93). By univariate analysis, tumour location, size and ablation time were significant risk factors of LTP. Multivariate analysis identified tumour size (>3.0 cm) to be the only independent predictor of LTP. CONCLUSIONS MWA of liver malignancies achieves a relatively low-incidence LTP, although LTP risk significantly increases if tumour size >3.0 cm. The technique seems to be appropriate even for patients with a tumour at a risk location. KEY POINTS • Microwave ablation of liver malignancies achieves a low incidence local tumour progression. • LTP risk significantly increases if the tumour size is >3.0 cm. • MWA seems to be appropriate even for patients with a tumour at a risk location.

Abstract
BACKGROUND/PURPOSE In patients with hepatocellular carcinoma (HCC), gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) often identifies non-hypervascular hypointense hepatic nodules during the hepatobiliary phase, but their prognostic significance is unclear. We conducted a prospective observational study to investigate the impact of non-hypervascular hypointense hepatic nodules detected by Gd-EOB-DTPA-enhanced MRI on the outcome of patients with early-stage HCC. METHODS Post-treatment recurrence and survival rates were analyzed in 138 patients with non-recurrent, early-stage HCC [Barcelona Clinic Liver Cancer (BCLC) stage 0 or A] and Child-Pugh A liver function according to the presence of non-hypervascular hypointense nodules on pretreatment Gd-EOB-DTPA-enhanced MRI. RESULTS Non-hypervascular hypointense hepatic nodules were detected in 51 (37.0%) patients with early-stage HCC on pretreatment Gd-EOB-DTPA-enhanced MRI. Recurrence rates were significantly higher in patients with non-hypervascular hypointense nodules (p < 0.0001). Based on a multivariate analysis, the presence of non-hypervascular hypointense hepatic nodules on Gd-EOB-DTPA-enhanced MRI was independently associated with an increased recurrence rate, independent of tumor progression or treatment (p = 0.0005). The survival rate was significantly lower in patients with non-hypervascular hypointense nodules on Gd-EOB-DTPA-enhanced MRI (p = 0.0108). CONCLUSIONS In patients with early-stage typical HCC (BCLC 0 or A), the presence of concurrent non-hypervascular hypointense hepatic nodules in the hepatobiliary phase of pretreatment Gd-EOB-DTPA-enhanced MRI is an indicator of higher likelihood of recurrence after treatment and may be a marker for unfavorable outcome.

Abstract
Purpose Early recurrence after hepatectomy is a well-known poor prognostic factor in patients with hepatocellular carcinoma. This study was undertaken to identify the risk factors of early recurrence in patients with hepatocellular carcinoma after hepatectomy. Methods One hundred and sixty-seven patients that underwent hepatectomy for hepatocellular carcinoma from January 2005 to December 2010 were enrolled. The numbers of patients with or without early recurrence group were 40 and 127, respectively. Clinico-pathologic factors were retrospectively analyzed. Results Potential risk factors were classified as host, tumor, or surgical factors. Of the host factors examined, lobular hepatitis activity was found to be a significant risk factor of early recurrence, and of the tumor factors, infiltrative type of gross appearance, level of preoperative AFP and worst Edmondson-Steiner grade were significant. Conclusion The present study shows that an infiltrative gross appearance, a high preoperative AFP level, high lobular hepatitis activity, and a poor Edmondson-Steiner grade are independent risk factors of early recurrence. Accordingly, patients with these risk factors should be followed closely after hepatectomy.

A meta-analysis of adjuvant therapy after potentially curative treatment for hepatocellular carcinoma. CANADIAN JOURNAL OF GASTROENTEROLOGY = JOURNAL CANADIEN DE GASTROENTEROLOGIE 2014; 27:351-63.

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
PURPOSE To clarify the prognostic impact of the hepatitis C virus (HCV) genotype after curative resection for hepatocellular carcinoma (HCC). METHODS A total of 199 patients who underwent a curative hepatic resection for HCV-related HCC were reviewed. The clinical outcomes were compared between patients infected with HCV genotype 1b (n = 160) and those infected with other genotypes (n = 39). RESULTS With a comparable median HCV viral load (6.0 vs. 5.8 log10 IU/mL, p = 0.17), the 3-year recurrence-free survival (RFS) rates (25 vs. 20 %, p = 0.65) and the 5-year overall survival (OS) rates (72 vs. 65 %, p = 0.73) were similar between the two groups. A multivariate analysis confirmed that HCV viral load of +1.0 log10 IU/mL [hazard ratio (HR), 1.48], major vascular invasion (HR, 3.20), recurrent tumor (HR, 1.77), and preoperative des-gamma carboxyprothrombin level >40 mAu/mL (HR, 1.64) were independent predictors of tumor recurrence, while the HCV genotype was not a significant risk factor. When the population was stratified according to the HCV viral load, a significant difference was observed in the RFS rate for both genotype 1b (p = 0.003) and the other genotypes (p = 0.037) at HCV viral load of 5.3 log10 IU/mL. CONCLUSIONS The HCV genotype does not affect the surgical outcomes of patients with HCC. A lower HCV viral load is advantageous regardless of the HCV genotype.

One of the key features of hepatocellular carcinoma (HCC) is the high rate of intrahepatic recurrence that correlates with poor prognosis. Therefore, in order to improve the clinical outcome for patients with HCC, development of a chemopreventive agent that can decrease or delay the incidence of recurrence is a critical issue for urgent investigation. Acyclic retinoid (ACR), a synthetic retinoid, successfully improves HCC patient survival by preventing recurrence and the formation of secondary tumors. A malfunction of the retinoid X receptor-α (RXRα) due to phosphorylation by the Ras-MAPK signaling pathway plays a critical role in liver carcinogenesis, and ACR exerts chemopreventive effects on HCC development by inhibiting RXRα phosphorylation. Here, we review the relationship between retinoid signaling abnormalities and liver disease, the mechanisms of how RXRα phosphorylation contributes to liver carcinogenesis, and the detailed effects of ACR on preventing HCC development, especially based on the results of our basic and clinical research. We also outline the concept of “clonal deletion and inhibition” therapy, which is defined as the removal and inhibition of latent malignant clones from the liver before they expand into clinically detectable HCC, because ACR prevents the development of HCC by implementing this concept. Looking toward the future, we discuss “combination chemoprevention” using ACR as a key drug since it can generate a synergistic effect, and may thus be an effective new strategy for the prevention of HCC.

Abstract
BACKGROUND CD44 is well known to be one of the cancer stem cell markers and is a cell-surface glycoprotein involved in cell-cell interactions, cell adhesion, and cell migration. We investigated the role of CD44 expression in both tumor and non-tumor tissues on recurrence of hepatocellular carcinoma (HCC). METHODS Forty-eight patients with HCC who underwent hepatic resection at our institution were enrolled in this study. CD44 expressions in both tumor and non-tumor tissues were examined using real time reverse transcription-polymerase chain reaction. The patients were divided into two groups: high and low gene-expression group, based on the CD44 expression level. We compared the clinicopathological factors between the high expression and low expression groups in both tumor and non-tumor tissues. RESULTS In the tumor tissues, the gene-expression levels of CD44 did not correlate with any clinicopathological parameters. The disease-free survival rate showed no significant difference between the two groups. In non-tumor tissues, although there was no significant relationship between the CD44 expression levels and clinicopathological factors, disease-free survival rate in the CD44 low expression group was significantly better than that in the CD44 high expression group (P < 0.05). In multivariate analysis, the risk factors in tumor recurrence were presence of microscopic portal invasion and high expression level of CD44. CONCLUSION The CD44 expressions in the non-tumor tissues may predict HCC recurrence.

Abstract
PURPOSE To evaluate retrospectively whether technical factors of hepatic arterial embolization affect the prognosis of patients with hepatocellular carcinoma (HCC). MATERIALS AND METHODS Inclusion criteria of this study were the following: (1) patients received embolization as the initial treatment during 2003-2004, (2) Child A or B liver profile, (3) five or fewer HCCs with maximum diameter of 7 cm or smaller, and (4) no extrahepatic metastasis. Patient data were gathered from 43 centers. Prognostic factors were evaluated using univariate and multivariate analyses. RESULTS Eight hundred fifteen patients were enrolled. The 1-, 3-, 5-, and 7-year overall survival rates were 92.0 % (95 % CI 90.1-93.9), 62.9 % (95 % CI 59.3-66.6), 39.0 % (95 % CI 35.1-43.0), and 26.7 % (95 % CI 22.6-30.8) in all patients. Univariate analysis showed a Child-Pugh class-A, alpha-fetoprotein level lower than 100 ng/ml, tumor size of 3 cm or smaller, tumor number of 3 or fewer, one-lobe tumor distribution, nodular tumor type, within the Milan criteria, stage I or II, no portal venous invasion, use of iodized oil, and selective embolization were significantly better prognostic factors. In the multivariate Cox model, the benefit to survival of selective embolization remained significant (hazard ratio 0.68; 95 % CI 0.48-0.97; p = 0.033). CONCLUSION Selective embolization contributes to survival in patients with HCCs.
