A study on prevention of bleeding complications using lusutrombopag for safe RFA in patients with hepatocellular carcinoma with low platelet counts: prospective observational study. BMC Gastroenterol 2023; 23:250. [PMID: 37488476 PMCID: PMC10364390 DOI: 10.1186/s12876-023-02879-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 07/11/2023] [Indexed: 07/26/2023] Open
Abstract
BACKGROUND Platelet (PLT) transfusion was the most practical way to increase patients' PLT counts before invasive hepatic procedures such as radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). A novel drug that raises the PLT count by acting on the thrombopoietin receptor has recently become available. METHODS Lusutrombopag 3 mg was administered daily for 7 days to patients who underwent RFA for liver tumors with low PLT counts (< 50,000 PLT µL- 1). We collected demographic data concerning the patients' liver function and PLT counts. RESULTS Lusutrombopag was administered to 91 patients, with a median age of 71 years (range 51-86). Forty-two patients had hepatitis C, 12 had hepatitis B, 21 had alcoholic liver disease, 11 had nonalcoholic steatohepatitis, and five had other diseases. The median Child-Pugh score was 7 (range 5-11). Thirty-seven patients had stage I tumors, 41 had Stage II, 12 had stage III, and one had stage IV. PLT count was elevated from 4.4 × 104 ± 1.4 × 104 to 8.6 × 104 ± 2.5 × 104 PLT µL- 1. Lusutrombopag administration prevented PLT transfusions in 84/91 patients (92%). No patient had bleeding complications after RFA. One had portal thrombosis after lusutrombopag administration. Patients who achieved PLT counts of > 50,000 PLT µL- 1 had higher PLT counts before lusutrombopag administration. The degree of splenomegaly did not affect the rate of PLT count elevation. There was no specific adverse effect by administrating lusutrombopag for patients with PLT counts of around 50,000 µL- 1 but > 50,000 µL- 1. CONCLUSIONS Lusutrombopag administration before RFA was effective and seemed to be relatively safe for hepatocellular carcinoma patients with low PLT counts. TRIAL REGISTRATION This study was approved by Japanese Red Cross Medical Center Institutional Reseach Comittie (#862, 07/03/2016), and was registered in a publically accessible primary register (#UMIN000046629, registered date: 14/01/2022).

Machine learning for individualized prediction of hepatocellular carcinoma development after the eradication of hepatitis C virus with antivirals. J Hepatol 2023; 79:S0168-8278(23)00424-5. [PMID: 37716372 DOI: 10.1016/j.jhep.2023.05.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 04/03/2023] [Accepted: 05/23/2023] [Indexed: 09/17/2023]
Abstract
BACKGROUND AND AIMS Accurate risk stratification for hepatocellular carcinoma (HCC) after achieving a sustained viral response (SVR) is necessary for optimal surveillance. We aimed to develop and validate a machine learning (ML) model to predict the risk of HCC after achieving an SVR in individual patients. METHODS In this multicenter cohort study, 1742 patients with chronic hepatitis C who achieved an SVR were enrolled. Five ML models were developed including DeepSurv, gradient boosting survival analysis, random survival forest (RSF), survival support vector machine, and a conventional Cox proportional hazard model. Model performance was evaluated using Harrel' c-index and was externally validated in an independent cohort (977 patients). RESULTS During the mean observation period of 5.4 years, 122 patients developed HCC (83 in the derivation cohort and 39 in the external validation cohort). The RSF model showed the best discrimination ability using seven parameters at the achievement of an SVR with a c-index of 0.839 in the external validation cohort and a high discriminative ability when the patients were categorized into three risk groups (P <0.001). Furthermore, this RSF model enabled the generation of an individualized predictive curve for HCC occurrence for each patient with an app available online. CONCLUSIONS We developed and externally validated an RSF model with good predictive performance for the risk of HCC after an SVR. The application of this novel model is available on the website. This model could provide the data to consider an effective surveillance method. Further studies are needed to make recommendations for surveillance policies tailored to the medical situation in each country. IMPACT AND IMPLICATIONS A novel prediction model for HCC occurrence in patients after hepatitis C virus eradication was developed using machine learning algorithms. This model, using seven commonly measured parameters, has been shown to have a good predictive ability for HCC development and could provide a personalized surveillance system.

The incidence of all organ malignancies and overall survival of patient with sustained virological response of HCV-comparable to SMR (standardized mortality ratio) of Japan general population. Hepatol Int 2023; 17:562-572. [PMID: 36811823 DOI: 10.1007/s12072-023-10495-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Accepted: 01/24/2023] [Indexed: 02/24/2023]
Abstract
OBJECTIVE This study prospectively observed the incidence of all malignancies and the prognosis of all patients in a population of patients who achieved Sustained Virological Response (SVR) with a 100% capture rate. DESIGN A prospective study of 651 SVR cases was conducted from July 2013 to December 2021. The primary endpoint was the occurrence of all malignancies, and the secondary endpoint was overall survival. The cancer incidence during the follow-up period was calculated using the man-year method, and risk factors were analyzed. In addition, sex- and age-matched standardized mortality ratio (SMR) was used to compare the general population with the study population. RESULTS The overall median follow-up was 5.44 years. 107 malignancies occurred in 99 patients during the follow-up. The incidence of all malignancies was 3.94/100 person-years. The cumulative incidence was 3.6% at 1 year, 11.1% at 3 years, and 17.9% at 5 years, and continued to increase almost linearly. The incidence of liver cancer and non-liver cancer was 1.94/100 patient-years vs. 1.81%/100 patient-years. The 1-year, 3-year, and 5-year survival rates were 99.3%, 96.5%, and 94.4%, respectively. This life expectancy was compared to the standardized mortality ratio of the Japanese population, which proved non-inferior. CONCLUSION It was found that malignancies of other organs occur as frequently as hepatocellular carcinoma (HCC). Therefore, follow-up of patients who have achieved SVR should focus not only on HCC but also on malignant tumors of other organs, and lifelong follow could contribute prolonged life expectancy for the previously short-lived.

Abstract
An 81-year-old woman was admitted to our hospital due to frequent bleeding and hemorrhagic shock. Blood tests revealed anemia and contrast-enhanced abdominal CT revealed a pancreatic tail tumor with a diameter of 60 mm. The boundary between pancreatic tumor and the transverse colon, stomach and spleen was unclear, and invasion of the transverse colon as well as the stomach and spleen was suspected. Hemorrhage due to colon invasion of the pancreatic tail cancer and intra-tumoral hemorrhage were suspected. Due to persistent bleeding, the patient had emergency surgery to control bleeding. The pancreatic tail tumor invaded not only the colon but also stomach and spleen, distal pancreatectomy, partial gastrectomy and splenectomy was performed in combination with resection of the transverse colon, and transverse colon colostomy. We report a case of gastrointestinal bleeding caused by transverse colon invasion of pancreatic tail cancer, which resulted in emergency surgery.

Intra-abdominal ectopic bronchogenic cyst with a mucinous neoplasm harboring a GNAS mutation: A case report. World J Clin Cases 2022; 10:8709-8717. [PMID: 36157792 PMCID: PMC9453374 DOI: 10.12998/wjcc.v10.i24.8709] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 04/23/2022] [Accepted: 07/17/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Bronchogenic cysts are congenital cysts caused by abnormal sprouting from the ventral foregut during fetal life. They usually occur in the mediastinum or lung, but there are very rare cases of ectopic bronchogenic cysts that develop in the abdominal cavity. A unique intra-abdominal ectopic bronchogenic cyst with a mucinous neoplasm that was producing carcinoembryonic antigen (CEA), harboring a GNAS mutation, is reported. The present case may contribute to clarifying the mechanism of tumorigenesis and malignant transformation of ectopic bronchogenic cysts.
CASE SUMMARY In 2007, a man in his 50s was incidentally found to have an intra-abdominal cystic mass, 8 cm in diameter. Surgical resection was recommended, but he preferred to remain under observation. In 2020, his serum CEA level increased to 26.7 ng/mL, and abdominal computed tomography showed a 15 cm × 12 cm, multifocal, cystic mass located predominantly on the lesser curvature of the stomach. Since malignancy could not be ruled out, he finally underwent surgical resection. Histologically, the cystic wall was lined by ciliated columnar epithelium, accompanied by bronchial gland-like tissue, bronchial cartilage, and smooth muscle. Part of the cyst consisted of atypical columnar epithelium with an MIB-1 index of 5% and positive for CEA. Moreover, a GNAS mutation (p.R201C) was detected in the atypical epithelium, leading to a diagnosis of an ectopic bronchogenic cyst with a low-grade mucinous neoplasm. The patient is currently undergoing outpatient follow-up without recurrence.
CONCLUSION An extremely rare case of an abdominal bronchogenic cyst with a low-grade mucinous neoplasm harboring a GNAS mutation was reported.

Abstract
Hepatocellular carcinoma is one of the leading causes of cancer-related death both in Japan and globally. In the advanced stage, hepatic arterial infusion chemotherapy (HAIC) is one of the most commonly used treatment options for liver cancer in Japan, and implantation of a catheter system (called a port system) in the body is a treatment method that has evolved mainly in Japan. The Guideline Committee of the Japanese Society of Interventional Radiology and the Japanese Society of Implantable Port Assisted Treatment jointly published clinical practice guidelines for HAIC with a port system to ensure its appropriate and safe performance in Japanese in 2018. We have written an updated English version of the guidelines with the aim of making this treatment widely known to experts globally. In this article, the evidence, method, indication, treatment regimen, and maintenance of the system are summarized.

Abstract
Hepatitis B virus (HBV) infection is one of the serious health problems in the world as HBV causes severe liver diseases. Moreover, HBV reactivation has occasionally been observed in patients with resolved HBV infection and patients using immunosuppression and anticancer drugs. Large-scale hospital data focused on HBV infection and severe liver function were analyzed at our hospital, located in an urban area adjacent to Tokyo, the capital city of Japan. A total of 99,932 individuals whose blood samples were taken at 7,170,240 opportunities were analyzed. The HBV surface antigen (HBsAg)-positive group had a more frequent prevalence of patients with higher transaminase elevations than the HBsAg-negative group. However, among the HBsAg-negative group, patients who were positive for anti-HBV surface antibody and/or anti-HBV core antibody, had more severe liver conditions and fatal outcomes. More careful attention should be paid to alanine transaminase (ALT) elevations higher than 1000 IU/L in patients who had current and previous HBV infection.

Effectiveness of direct acting antiviral agents for hepatitis C virus related recurrent hepatocellular carcinoma patients who had multiple courses of recurrence. J Viral Hepat 2021; 28:1597-1603. [PMID: 34312954 DOI: 10.1111/jvh.13579] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 06/16/2021] [Accepted: 07/21/2021] [Indexed: 12/16/2022]
Abstract
Eradication of hepatitis C virus (HCV) using direct acting antiviral agents (DAAs) has been reported to alter liver function and reduce the recurrence rate after curative treatment in naïve hepatocellular carcinoma (HCC) patients. However, it is not well known whether administration of DAAs had favourable effect on HCC patients with multiple courses of recurrence. We retrospectively extracted 146 HCV-related HCC (C-HCC) patients who received curative treatment using radiofrequency ablation (RFA) followed by eradication treatment with DAA between 1 January 2015 and 31 December 2017. We also extracted 184 C-HCC patients who were curatively treated using RFA without HCV eradication treatment between 1 January 2009 and 31 July 2014 as controls. We used propensity score matching method and adjusted following factors between the 2 groups: age, sex, liver function, number of recurrence times, tumour diameter and tumour numbers. We finally enrolled 47 C-HCC patients with eradication of HCV, and 47 C-HCC patients without HCV eradication as controls. Primary end point was time to curative treatment failure. We defined time to curative treatment failure as the interval from curative treatment initiation to premature discontinuation of this type of therapy. Their clinical data, time to curative treatment failure and overall survival were compared. We also assessed the prognostic values of time to curative treatment failure and overall survival using multivariate Cox proportional hazard models. The median age was 74.8 years, 60 patients (63.8%) were male, and 81 patients (86.2%) were Child-Pugh class A. The median tumour number was 1, tumour diameter was 20 mm, and frequency of recurrence was 3 times. There were no significant differences about patients' backgrounds between the 2 groups. The cumulative time to curative treatment failure rates of patients who received DAA were 93.6% and 73.2% at 1 and 3 years, respectively; those of controls were 72.5%, and 37.1% (p < .01). Multivariate analysis indicated that eradication with DAAs (HR 0.23, 95% CI; 0.12-0.43, p < .01) and DCP >50 mAU/ml (HR 2.62, 95% CI; 1.45-4.74, p < .01) as independent factors contributed to time to curative treatment failure. The cumulative overall survival rates of patients who received DAAs were 93.6% and 72.6% at 1 and 3 years, respectively; those of controls were 72.8% and 37.4% (p < .01). Multivariate analysis indicated that eradication with DAAs (HR 0.32, 95% CI; 0.17-0.60, p < .01) and frequency of recurrence times (HR 1.20 per 1 time, 95% CI; 1.01-1.42, p = .038) as independent factors related to overall survival. Eradication of HCV using DAAs prolonged not only time to curative treatment failure but also overall survival even in C-HCC patients with multiple courses of recurrence.

Abstract
BACKGROUND AND AIMS It remains unclear whether obesity increases the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis C who achieved a sustained virological response (SVR) with antiviral therapy. METHODS In this multicenter cohort study, we enrolled patients with chronic hepatitis C who achieved SVR with interferon (IFN)-based therapy (IFN group) or direct-acting antiviral (DAA) therapy (DAA group) between January 1, 1990, and December 31, 2018. The patients underwent regular surveillance for HCC. Cumulative incidence of and the risk factors for HCC development after SVR were assessed using the Kaplan-Meier method and Cox proportional hazard regression analysis, respectively. RESULTS Among 2,055 patients (840 in the IFN group and 1,215 in the DAA group), 75 developed HCC (41 in the IFN group and 34 in the DAA group) during the mean observation period of 4.1 years. The incidence rates of HCC at 1, 2, and 3 years were 1.2, 1.9, and 3.0%, respectively. Multivariate analysis revealed that in addition to older age, lower albumin level, lower platelet count, higher alpha-fetoprotein level, and absence of dyslipidemia, obesity (body mass index ≥25 kg/m2) and heavy alcohol consumption (≥60 g/day) were independent risk factors for HCC development, with adjusted hazard ratio (HR) of 2.53 (95% confidence interval [CI]: 1.51-4.25) and 2.56 (95% CI: 1.14-5.75), respectively. The adjusted HR was not significant between the 2 groups (DAA vs. IFN; HR 1.19, 95% CI: 0.61-2.33). CONCLUSIONS Obesity and heavy alcohol consumption increased the risk of HCC development after SVR.

Abstract
Objective Liver injury is a notable complication of coronavirus disease 2019 (COVID-19). This study aimed to clarify the clinical features and liver injury in Japanese patients with COVID-19. Methods We conducted a multicenter retrospective cohort study. All consecutive patients with COVID-19 who visited or were admitted to our hospital before May 12, 2020, were enrolled. Their demographics, symptoms, laboratory findings, comorbidities, concomitant drugs, treatment, and clinical course were reviewed. We defined liver injury as alanine aminotransferase (ALT) or gamma-glutamyl transferase (GGT) levels over the upper limit of normal. Results Twenty-two patients with COVID-19 (median age, 47 years old; men/women, 13/9) were enrolled. Two patients had underlying liver diseases, and two were diagnosed as having COVID-19 without any symptoms. Elevated ALT and GGT levels were found in 12 and 12 patients, respectively, and liver injury was observed in 15 patients (68.2%). Compared with the patients without liver injury, those with liver injury had a significantly higher fever during the clinical course (median, 37.5°C vs. 38.8°C, p=0.006). A significant correlation was found between the highest serum liver values and the highest body temperature in each patient. Among the 22 patients, 4 required artificial respiratory support, and 2 died thereafter. Liver injury was not associated with the severity or mortality of COVID-19. Conclusion Elevated levels of liver enzymes in the Japanese patients with COVID-19 were associated with the highest body temperature during the clinical course but not with the severity or mortality of COVID-19.

Abstract
BACKGROUND Prior to the approval of sorafenib, hepatic arterial infusion chemotherapy (HAIC) was offered to patients with advanced hepatocellular carcinoma (HCC) in East Asia, particularly Japan. According to the Japanese guidelines, HAIC is recommended as one of the treatment options in patients without extrahepatic metastasis (EHM). METHODS The present cohort study compared the use of HAIC and sorafenib on outcomes of patients with advanced HCC. Consecutive patients with advanced HCC who received HAIC or sorafenib as a first-line systemic therapy were enrolled from 10 Japanese institutions. The primary outcomes were overall survival (OS) in patients with macrovascular invasion (MVI), but without EHM, and OS in patients without both MVI and EHM. RESULTS Between 2009 and 2016, 2,006 patients were enrolled (541 HAIC patients, 1,465 sorafenib patients). After propensity score matching, the OS of patients with MVI but without EHM was significantly longer in the HAIC group compared with the sorafenib group (10.1 vs. 9.1 months for the HAIC and sorafenib groups, respectively; n = 170 for each group; hazard ratio [HR] 0.668; 95% confidence interval [95% CI] 0.475-0.935; p = 0.018). There was no significant difference in OS between patients without both MVI and EHM (12.2 vs. 15.4 months for the HAIC and sorafenib groups, respectively; n = 76 in each cohort after propensity score matching; HR 1.227; 95% CI 0.699-2.155; p = 0.475). CONCLUSION HAIC is a potential front-line treatment choice in a subpopulation of patients with advanced HCC with MVI but without EHM.

Abstract
Background and Objective Experience of the use of lenvatinib (LEN) in the clinical setting remains limited. We conducted this study to elucidate the factors associated with progression-free survival (PFS) in patients with advanced HCC treated with LEN. Methods In this multicenter retrospective study, we analyzed data on patient characteristics, treatment outcomes, and adverse events (AEs) for 77 patients with advanced hepatocellular carcinoma (HCC). We also analyzed PFS and factors that influence PFS. Results The response rate to LEN was 29.9% and the disease control rate was 77.9%. Patients who achieved relative dose intensities of more than 70% had better outcomes (response rate 45.2% vs. 11.4%, P < 0.01). Appetite loss, fatigue, diarrhea, hypertension, and thyroid dysfunction were the most frequent AEs. Twenty-three patients (29.9%) had grade 3 or 4 AEs. Fifty-two patients (67.5%) required a dose reduction and 47 (61.0%) stopped taking the drug due to AEs. The PFS rates at 3, 6, and 12 months were 81.2%, 49.8%, and 34.8%, respectively. The median PFS was 5.6 months. Multivariate analysis showed that thyroid dysfunction of grade ≥ 2 (hazard ratio [HR] 4.57, 95% confidence interval [CI] 2.05–10.2, P < 0.01), appetite loss (HR 3.58, 95% CI 1.72–7.52, P < 0.01), and tumor diameter ≥ 40 mm (HR: 2.27, 95% CI 1.17–4.40, P = 0.015) were independent factors associated with poor PFS. On the other hand, Child–Pugh class 5A (HR 0.41, 95% CI 0.19–0.90, P = 0.027) and complete or partial response (HR 0.40, 95% CI 0.17–0.95, P = 0.039) were independent factors associated with better PFS. Conclusions Thyroid dysfunction and appetite loss after the administration of LEN were independent factors associated with shorter PFS, so these AEs should be carefully managed after administering LEN.

Abstract
OBJECTIVE In SILIUS (NCT01214343), combination of sorafenib and hepatic arterial infusion chemotherapy did not significantly improve overall survival (OS) in patients with advanced hepatocellular carcinoma (HCC) compared with sorafenib alone. In this study, we explored the relationship between objective response by mRECIST and OS in the sorafenib group, in the combination group, and in all patients in the SILIUS trial. METHODS Association between objective response and OS in patients treated with sorafenib (n = 103) or combination (n = 102) and all patients (n = 205) were analyzed. The median OS of responders was compared with that of non-responders. Landmark analyses were performed according to objective response at several fixed time points, as sensitivity analyses, and the effect on OS was evaluated by Cox regression analysis with objective response as a time-dependent covariate, with other prognostic factors. RESULTS In the sorafenib group, OS of responders (n = 18) was significantly better than that of non-responders (n = 78) (p < 0.0001), where median OS was 27.2 (95% CI, 16.0-not reached) months for responders and 8.9 (95% CI, 6.5-12.6) months for non-responders. HRs from landmark analyses at 4, 6, and 8 months were 0.45 (p = 0.0330), 0.37 (p = 0.0053), and 0.36 (p = 0.0083), respectively. Objective response was an independent predictor of OS based on unstratified Cox regression analyses. In the all patients and the combination group, similar results were obtained. CONCLUSIONS In the SILIUS trial, objective response by sorafenib assessed by mRECIST is an independent prognostic factor for OS in patients with HCC.

Abstract
323 Background: Sorafenib, approved in Japan in 2009, is the first systemic therapy demonstrated to significantly improve overall survival (OS) in patients with advanced hepatocellular carcinoma (HCC). In Japan, hepatic arterial infusion chemotherapy (HAIC), which directly delivers high concentrations of cytotoxic agents to liver tumors, has been offered to patients with advanced HCC since before sorafenib was approved. HAIC is particularly used in patients without extrahepatic metastases (EHM). This study aimed to compare the outcomes of patients with advanced HCC who received HAIC and sorafenib. Methods: Consecutive patients with advanced HCC who received sorafenib or HAIC as the first-line systemic therapy were enrolled from 10 Japanese centers. The statistical analysis plan included pre-defined propensity score matching method and risk factors. All statistical analyses were performed by an independent biostatistician. Results: Between June 2009 and May 2016, 2006 patients were enrolled (sorafenib: 1465 patients, HAIC: 541 patients). The mean OS of patients with macrovascular invasion (MVI) and without EHM was significant longer in the HAIC group compared with the sorafenib group. After propensity score matching, there were 172 patients in each cohort. The OS was 9.1 months for the sorafenib group and 10.1 months for the HAIC group (hazard ratio [HR]: 0.668 [95% CI: 0.475–0.935], P = 0.018). There was no significant difference in OS between patients without both MVI and EHM. After propensity score matching, there were 76 patients in each cohort. The OS was 15.4 months for the sorafenib group and 12.2 months for the HAIC group (hazard ratio [HR]: 1.227 [95% CI: 0.699–2.155], P = 0.475). Conclusions: HAIC might be a potential initial treatment for patients with advanced HCC with MVI (without EHM). Currently, several new drugs appear clinically beneficial for patients with advanced HCC. Although this study only focused on sorafenib as the chemo-agent, additional studies should be conducted to confirm the benefits associated with HAIC in a limited population of patients with advanced HCC.

Abstract
A 65-year-old woman who had liver cirrhosis(Child-Pugh class B)due to hepatitis C infection was diagnosed with hepatocellular carcinoma with hepatic vein invasion, portal vein tumor invasion, and lung metastasis. No recommended treatment was noted in the clinical practice guidelines for hepatocellular carcinoma with vascular invasion in patients with Child- Pugh class B liver cirrhosis. After initiating arterial injection chemotherapy, marked decreases in tumor size of lung metastasis, vascular invasion, and primary liver cancer were observed. Based on our experience and previous reports, hepatic arterial infusion chemotherapy was considered valuable for hepatocellular carcinoma with vascular invasion, even in patients with Child-Pugh class B liver cirrhosis.

Multicenter, randomized, controlled trial of S-1 monotherapy versus S-1 and interferon-α combination therapy for hepatocellular carcinoma with extrahepatic metastases. Hepatol Res 2018; 48:717-726. [PMID: 29377364 DOI: 10.1111/hepr.13067] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2017] [Revised: 01/20/2018] [Accepted: 01/24/2018] [Indexed: 02/08/2023]
Abstract
AIM No effective therapies for extrahepatic metastases from hepatocellular carcinoma (HCC) have yet been identified. Previous studies suggested a potentially promising antitumor effect of combination therapy of S-1, a novel oral dihydropyrimidine dehydrogenase inhibitor, and interferon (IFN)-α. The present study aimed to investigate the clinical efficacy of single agent S-1 and S-1/IFN-α for HCC patients with extrahepatic metastases in a randomized, open-label, multicenter trial. METHODS A total of 103 patients with HCC with extrahepatic metastases were randomly assigned to the S-1/IFN-α group, receiving the combination of S-1 and IFN-α, or the S-1 group, receiving the single agent of S-1. Clinical efficacy and adverse events were compared between the two groups. RESULTS A total of 49 patients in the S-1/IFN-α group and 51 patients in the S-1 group were included in the efficacy analysis. The response rate was 22.4% (11/49) in the S-1/IFN-α group and 13.7% (7/51) in the S-1 group; there was no significant difference. Overall and progression-free survival in the two groups were also not significantly different (1-year overall survival 50.8% vs. 72.4%, median progression-free survival 127 days vs. 157 days). The incidence of grade ≥3 adverse events in the S-1/IFN-α group was 62.7% (32/51), which tended to be higher than in the S-1 group (43.1% [22/51]). CONCLUSIONS Oncological outcomes in both treatment groups were favorable compared with previous reports, though there was no significant beneficial effect of adding IFN-α to S-1 for the treatment of HCC patients with extrahepatic metastases.

Regional Differences in Efficacy, Safety, and Biomarkers for Second-Line Axitinib in Patients with Advanced Hepatocellular Carcinoma: From a Randomized Phase II Study. Liver Cancer 2018; 7:148-164.

Abstract
BACKGROUND An unmet need exists for treatment of patients with advanced hepatocellular carcinoma (HCC) who progress on or are intolerant to sorafenib. A global randomized phase II trial (ClinicalTrial.gov No. NCT01210495) of axitinib, a vascular endothelial growth factor receptor 1-3 inhibitor, in combination with best supportive care (BSC) did not prolong overall survival (OS) over placebo/BSC, but showed improved progression-free survival in some patients. Subgroup analyses were conducted to identify potential predictive/prognostic factors. METHODS The data from this phase II study were analyzed for the efficacy and safety of axitinib/BSC in patients from Asia versus non-Asia versus Asian subgroups (Japan, Korea, or mainland China/Hong Kong/Taiwan) and predictive/prognostic values of baseline microRNAs and serum soluble proteins, using the Cox proportional hazards model. RESULTS Of 202 patients, 78 were from non-Asia and 124 from Asia (37 Japanese, 36 Korean, and 51 Chinese). No significant differences in OS were found between axitinib/BSC and placebo/BSC in non-Asians, Asians, or Asian subgroups. However, in an exploratory analysis, axitinib/BSC showed favorable OS in Asians, especially Japanese, when patients intolerant to prior antiangiogenic therapy were excluded from the data set. Axitinib/BSC was well tolerated by non-Asians and Asians alike. The presence of 4 circulating microRNAs, including miR-5684 and miR-1224-5p, or a level lower than or equal to the median protein level of stromal cell-derived factor 1 at baseline was significantly associated with longer OS in axitinib/BSC-treated Asians or non-Asians. CONCLUSIONS Axitinib/BSC did not prolong survival over placebo/BSC in non-Asians, Asians, or Asian subgroups, but favorable OS with axitinib/BSC was observed in a subset of Japanese patients. A patient population that excludes sorafenib-intolerant patients might potentially be more suitable for clinical trials of new agents in advanced HCC. Since these results are very preliminary, further investigation is warranted. The potential predictive/prognostic value of several baseline microRNAs and soluble proteins identified in this study would require validation in prospective studies on a large cohort of patients.

Sorafenib plus low-dose cisplatin and fluorouracil hepatic arterial infusion chemotherapy versus sorafenib alone in patients with advanced hepatocellular carcinoma (SILIUS): a randomised, open label, phase 3 trial. Lancet Gastroenterol Hepatol 2018; 3:424-432. [PMID: 29631810 DOI: 10.1016/s2468-1253(18)30078-5] [Citation(s) in RCA: 181] [Impact Index Per Article: 30.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2018] [Revised: 02/14/2018] [Accepted: 02/22/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND Hepatic arterial infusion chemotherapy plus sorafenib in phase 2 trials has shown favourable tumour control and a manageable safety profile in patients with advanced, unresectable hepatocellular carcinoma. However, no randomised phase 3 trial has tested the combination of sorafenib with continuous arterial infusion chemotherapy. We aimed to compare continuous hepatic arterial infusion chemotherapy plus sorafenib with sorafenib alone in patients with advanced, unresectable hepatocellular carcinoma. METHODS We did an open-label, randomised, phase 3 trial (SILIUS) at 31 sites in Japan. Eligible patients were aged 20 years or older, with advanced hepatocellular carcinoma not suitable for resection, local ablation, or transarterial chemoembolisation; Eastern Cooperative Oncology Group (ECOG) performance status 0-1; Child-Pugh score 7 or lower; and adequate bone marrow, liver, and renal function. Patients were randomly assigned (1:1) via an interactive web response system with a computer-generated sequence to receive 400 mg sorafenib orally twice daily or 400 mg sorafenib orally twice daily plus hepatic arterial infusion chemotherapy (cisplatin 20 mg/m2 on days 1 and 8 and fluorouracil 330 mg/m2 continuously on days 1-5 and 8-12 of every 28-day cycle via an implanted catheter system). The primary endpoint was overall survival. The primary efficacy analysis comprised all randomised patients (the intention-to-treat population), and the safety analysis comprised all randomised patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov, number NCT01214343. FINDINGS Between Nov 4, 2010, and June 10, 2014, 206 patients were randomly assigned (103 to the sorafenib group, 103 to the sorafenib plus hepatic arterial infusion chemotherapy group). One patient in the sorafenib plus hepatic arterial infusion chemotherapy group withdrew after randomisation. Median overall survival was similar in the sorafenib plus hepatic arterial infusion chemotherapy (n=102) and sorafenib monotherapy (n=103) groups (11·8 months [95% CI 9·1-14·5] vs 11·5 months [8·2-14·8]; hazard ratio 1·009 [95% CI 0·743-1·371]; p=0·955). Grade 3-4 adverse events that were more frequent in the sorafenib plus hepatic arterial infusion chemotherapy group than in the sorafenib monotherapy group included anaemia (15 [17%] of 88 vs six [6%] of 102), neutropenia (15 [17%] vs one [1%]), thrombocytopenia (30 [34%] vs 12 [12%]), and anorexia (12 [14%] vs six [6%]). INTERPRETATION Addition of hepatic arterial infusion chemotherapy to sorafenib did not significantly improve overall survival in patients with advanced hepatocellular carcinoma.

Abstract
BACKGROUND REACH evaluated ramucirumab in the second-line treatment of patients with advanced hepatocellular carcinoma. In the intent-to-treat population (n = 565), a significant improvement in overall survival (OS) was not observed. In patients with an elevated baseline α-fetoprotein (AFP) level (400 ng/mL or greater), an improvement in OS was demonstrated. An analysis of the Japanese patients in REACH was performed. METHODS An analysis was performed with the subset of the intent-to-treat population enrolled in Japan (n = 93). RESULTS The median OS was 12.9 months for the ramucirumab arm (n = 45) and 8.0 months for the placebo arm (n = 48) [hazard ratio (HR) 0.621 (95 % confidence interval (CI) 0.391-0.986); P = 0.0416]. The median progression-free survival was 4.1 months for the ramucirumab arm and 1.7 months for the placebo arm [HR 0.449 (95 % CI 0.285-0.706); P = 0.0004]. The objective response rates were 11 % for the ramucirumab arm and 2 % for the placebo arm (P = 0.0817). The grade 3 or higher treatment-emergent adverse events occurring in more than 5 % of patients with a higher incidence for the ramucirumab arm (n = 44) than for the placebo arm (n = 47) were ascites (7% vs 2 %), hypertension (7 % vs 2 %), and cholangitis (7 % vs 0 %). In patients with a baseline AFP level of 400 ng/mL or greater, the median OS was 12.9 months for the ramucirumab arm (n = 20) and 4.3 months for the placebo arm (n = 22) [HR 0.464 (95 % CI 0.232-0.926); P = 0.0263]. CONCLUSIONS In the Japanese patients in REACH, ramucirumab treatment improved OS, including in patients with a baseline AFP level of 400 ng/mL or greater; improvements in progression-free survival and objective response rate were also demonstrated. The safety profile of ramucirumab was acceptable and well tolerated in Japanese patients. ClinicalTrials.gov identifier NCT01140347.

Abstract
BACKGROUND The outcomes of treatment of ruptured varices in patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT) are unclear. We therefore evaluated the long- (rebleeding and death) and short-term (immediate death within 24 h of variceal bleeding diagnosis) outcomes of patients with PVTT who underwent emergency variceal band ligation. METHODS Data on 62 patients with PVTT and endoscopically proven esophageal or gastric variceal bleeding from 2007 to 2012 were studied. In most cases, the varices were treated using endoscopic variceal band ligation (EVL). We assessed the patients' rebleeding-free and overall survival using the Kaplan-Meier method, and a Cox proportional hazard model was used to analyze effect of independent factors on rebleeding-free and overall survival times. RESULTS Most patients had decompensated cirrhosis and were classified as Child-Pugh class B (56%) or C (36%). A total of 35 patients (56%) had PVTT in the main portal trunk. Among all patients, 58 (94%) and 4 (6%) had esophageal and gastric variceal bleeding, respectively. Bleeding was managed using EVL in all, but one patient (98%) who was treated with a Sengstaken-Blakemore tube. A total of 24 patients (39.3%) experienced rebleeding, and these patients had a median overall survival time of 36 days. A PVTT in the main portal trunk was predictive of rebleeding (hazard ratio 3.706, p = .0223), and α-fetoprotein-L3 levels <37.4% (hazard ratio 0.464, p = 0.015) and Child-Pugh class A/B (hazard ratio 0.398, p = 0.007) were associated with overall survival. We observed 95 bleeding events in 62 patients. EVL achieved hemostasis in 92 of the 95 bleeding events, whereas seven immediate deaths occurred due to variceal bleeding (7/92, 7.6%). All three bleeding events treated with modalities other than EVL resulted in immediate deaths. CONCLUSIONS EVL is a safe and effective treatment of variceal ruptures in patients with HCC and PVTT. After successful hemostasis, alleviation of the underlying liver function impairment and tumor control are equally important for a good prognosis.

Abstract
329 Background: A randomised, double-blind phase II study of axitinib plus BSC [AXI] vs placebo plus BSC [PBO] was conducted in HCC pts after failure of one antiangiogenic therapy. Primary outcome was presented at ESMO 2014. No significant differences in overall survival (OS) between two arms were noted overall and in pre-specified subgroup analysis (non-Asian [nA] and Asian [A]). Interestingly, improvements favouring AXI (P < 0.01) were observed in secondary efficacy endpoints and retained among A. Methods: Exploratory efficacy/safety/biomarker analyses were performed by geographic region (nA; A; A subgroups: Japan/Korea [JK] and China/Hong Kong/Taiwan [CHT]) including: OS excluding pts intolerant to prior therapy; relationship between a subset of 26 baseline micro RNAs (miR) and AXI effect. Results: 78 nA pts (76% male, 60% with vascular invasion/extrahepatic spread) and 124 A pts (73JK/51CHT) (86% [84% JK, 90% CHT] male; 86% [82% JK, 92% CHT] with vascular invasion/extrahepatic spread) were randomized. In regional subgroups, OS HR excluding pts intolerant to prior therapy was: nA HR = 0.700 (95% CI 0.373–1.316; p = 0.1318) for AXI (45) vs PBO (16); A HR = 0.653 (95% CI 0.415–1.027; p = 0.0312) for AXI (76) vs PBO (35); JK HR = 0.479 (95% CI 0.250–0.918; p = 0.0118) for AXI (46) vs PBO (17); CHT HR = 0.918 (95% CI 0.480–1.756; p = 0.3954) for AXI (30) vs PBO (18). AXI safety profile was generally similar in regional subgroups. Differences were seen in dose modification pattern: dose reduction or discontinuation due to adverse events in 24% nA / 41% A / 51% JK / 26% CHT or in 39% nA / 22% A / 16% JK / 32% CHT, respectively. miR analysis for OS showed a trend of predictive and/or prognostic effect in overall population (e.g., let-7e-5p); a strong predictive effect of multiple miR (e.g., miR-3648) was seen in A but not in nA. Conclusions: AXI showed favorable OS vs PBO in nA and A, particularly in JK, when pts intolerant to prior therapy were excluded, suggesting that pts who progress on prior therapy are more suitable population for new agent studies in HCC. Appropriate dose modifications may also play a role in treatment duration. Baseline miR signature may have predictive value for AXI OS in A. Clinical trial information: NCT01210495.

Abstract
BACKGROUND The efficacy and safety of axitinib, a potent and selective vascular endothelial growth factor receptors 1-3 inhibitor, combined with best supportive care (BSC) was evaluated in a global, randomized, placebo-controlled phase II trial in patients with locally advanced or metastatic hepatocellular carcinoma (HCC). PATIENTS AND METHODS Patients with HCC and Child-Pugh Class A who progressed on or were intolerant to one prior antiangiogenic therapy were stratified by tumour invasion (presence/absence of extrahepatic spread and/or vascular invasion) and region (Asian/non-Asian) and randomized (2:1) to axitinib/BSC (starting dose 5 mg twice-daily) or placebo/BSC. The primary end point was overall survival (OS). RESULTS The estimated hazard ratio for OS was 0.907 [95% confidence interval (CI) 0.646-1.274; one-sided stratified P = 0.287] for axitinib/BSC (n = 134) versus placebo/BSC (n = 68), with the median (95% CI) of 12.7 (10.2-14.9) versus 9.7 (5.9-11.8) months, respectively. Results of prespecified subgroup analyses in Asian versus non-Asian patients or presence versus absence of tumour invasion were consistent with the overall population. Improvements favouring axitinib/BSC (P < 0.01) were observed in secondary efficacy end point analyses [progression-free survival (PFS), time to tumour progression (TTP), and clinical benefit rate (CBR)], and were retained among Asian patients in the prespecified subgroup analyses. Overall response rate did not differ significantly between treatments and patient-reported outcomes favoured placebo/BSC. Most common all-causality adverse events with axitinib/BSC were diarrhoea (54%), hypertension (54%), and decreased appetite (47%). Baseline serum analyses identified potential new prognostic (interleukin-6, E-selectin, interleukin-8, angiopoietin-2, migration inhibitory factor, and c-MET) or predictive (E-selectin and stromal-derived factor-1) factors for survival. CONCLUSIONS Axitinib/BSC did not improve OS over placebo/BSC in the overall population or in stratification subgroups. However, axitinib/BSC resulted in significantly longer PFS and TTP and higher CBR, with acceptable toxicity in patients with advanced HCC. TRIAL REGISTRATION ClinicalTrials.gov, NCT01210495.

Abstract
BACKGROUND Hepatic arterial infusion chemotherapy (HAIC) is frequently used to treat advanced hepatocellular carcinoma (HCC) in Asian countries. However, there is a lack of evidence supporting the use of HAIC. SUMMARY Many studies report high response rates in patients with advanced HCC receiving HAIC, and clinical responses translate to survival benefits. Therefore, prediction of an antitumor response is important in selecting appropriate treatments. There are no proven post-sorafenib therapeutic measures or procedures for HCC patients with poor liver function, and HAIC is one of the few options for patients in these situations. Despite studies showing its effectiveness, the use of HAIC for treatment of advanced HCC is unclear because convincing data from large-scale randomized clinical trials are lacking. For HAIC to become a standard treatment for HCC, such trials must establish its efficacy compared with other HCC therapies; prediction of antitumor response in HAIC may aid trial design, and a multi-center, open-labelled, randomized clinical trial of HAIC in advanced HCC is currently in progress. Optimization of HCC treatment protocols and regimens is also required. KEY MESSAGE We think that both HAIC and sorafenib are effective treatments for advanced HCC, and this review presents evidence supporting this contention.

Abstract
Familial adenomatous polyposis (FAP) is a genetic disorder in which multiple colorectal polyps and cancers develop. However, the prevalence of small intestinal tumors in patients with FAP remains unclear. We elucidated the prevalence of polyps in the small intestine and duodenum using capsule endoscopy (CE). Patients with FAP receiving a periodic screening colonoscopy at Kyoundo Hospital were encouraged to participate in the study. All study participants underwent esophagogastroduodenoscopy (EGD) within 2 weeks before CE. Outcome measurements were the prevalence of duodenal polyps (DP) and small intestinal polyp (SIP), detectability of the ampulla of Vater, and concordance of the duodenal findings between CE and EGD. Twenty-three patients (mean age, 47 years; 15 males) were enrolled in the study. CE showed DPs in 11 patients (52%) and SIPs in nine patients (43 %). The mean numbers of DPs and SIPs was 11.5 ± 6.2 and 11.9 ± 10.9, respectively. SIPs were more often detected in patients with DPs versus those without (62 vs. 13%, P = 0.07). The ampulla of Vater was observed by CE in four patients (21%). EGD showed DPs in 13 patients (62%). EGD missed DPs in two of 11 patients with DPs detected by CE. EGD found DPs in four of 10 patients without DPs using CE. The kappa index was 0.422. Patients with FAP have a high prevalence of polyps in the small intestine. Although the clinical significance of small intestinal polyps remains unclear, patients with FAP seem to be good candidates for CE.

Abstract
Background: We previously reported that expressions of the pro-angiogenic cytokines angiopoietin-2 (Ang-2), follistatin, granulocyte colony-stimulating factor, hepatocyte growth factor, leptin, platelet-derived growth factor-BB, platelet endothelial cell adhesion molecule-1, and vascular endothelial growth factor were associated with the response to sorafenib in patients with advanced hepatocellular carcinoma (HCC). The aim of the present study is to examine the same relationship in a larger cohort. Methods: In the current retrospective cohort study, we measured serum levels of the eightcytokines in 120 consecutive HCC patients who were treated with sorafenib. We evaluated the effects of increased expression of serum cytokines on progression-free survival (PFS) and overall survival (OS). Results: Elevated expression of Ang-2 correlated both with significantly shorter PFS (hazard ratio (HR), 1.84; 95% confidence interval (CI), 1.21–2.81), and OS (HR, 1.95; 95% CI, 1.21–3.17). Patients with more than three cytokines expressed above the median similarly had significantly shorter PFS (HR, 1.98; 95% CI, 1.30–3.06) and OS (HR, 1.94; 95% CI, 1.19–3.22). Differences in OS were evident in cases with the evidence of macroscopic vascular invasion or extrahepatic metastasis. Conclusion: High expression of Ang-2 or more than cytokines in serum is associated with poor PFS and OS in HCC patients treated with sorafenib.

Abstract
AIM Tamibarotene is a synthetic retinoid expected to inhibit tumor-cell proliferation and to induce apoptosis by selective interaction with retinoic acid receptor α/β. We conducted an open-label phase I/II study to determine the maximum tolerated dose (MTD) and recommended dose (RD), and to evaluate the pharmacokinetics, efficacy, and safety profiles for advanced hepatocellular carcinoma (HCC). METHODS Patients with histologically confirmed, measurable, unresectable HCC of Child-Pugh classification A or B and with no effective systemic or local therapies were eligible. In phase I, patients were assigned based on the 3 + 3 dose escalation criteria to receive tamibarotene at 8, 12, and 16 mg/day. The RD determined in phase I was employed for phase II. The planned sample size in phase II was 25, including the RD-treated patients in phase I. RESULTS Thirty-six patients were enrolled. No patients experienced dose-limiting toxicity (DLT) at 8 mg/day. However, two out of six patients experienced the DLTs at 12 mg/day: one experienced thrombosis in a limb vein and pulmonary artery, and the other experienced an increase of γ-GTP. The MTD and RD were determined as 12 and 8 mg/day, respectively. In phase II, one patient achieved partial response, and seven achieved stable disease. The disease control rate was 32 % (95 % CI: 15.0-53.5). The following drug-related serious adverse events were reported: thrombosis in a limb vein, pulmonary artery, and portal vein; interstitial lung disease; and vomiting. CONCLUSIONS Tamibarotene demonstrated the inhibition of tumor cell growth in advanced HCC with acceptable tolerance.

MicroRNA-140 acts as a liver tumor suppressor by controlling NF-κB activity by directly targeting DNA methyltransferase 1 (Dnmt1) expression. Hepatology 2013; 57:162-70.

Abstract
UNLABELLED MicroRNAs (miRNAs) are small RNAs that regulate the expression of specific target genes. While deregulated miRNA expression levels have been detected in many tumors, whether miRNA functional impairment is also involved in carcinogenesis remains unknown. We investigated whether deregulation of miRNA machinery components and subsequent functional impairment of miRNAs are involved in hepatocarcinogenesis. Among miRNA-containing ribonucleoprotein complex components, reduced expression of DDX20 was frequently observed in human hepatocellular carcinomas, in which enhanced nuclear factor-κB (NF-κB) activity is believed to be closely linked to carcinogenesis. Because DDX20 normally suppresses NF-κB activity by preferentially regulating the function of the NF-κB-suppressing miRNA-140, we hypothesized that impairment of miRNA-140 function may be involved in hepatocarcinogenesis. DNA methyltransferase 1 (Dnmt1) was identified as a direct target of miRNA-140, and increased Dnmt1 expression in DDX20-deficient cells hypermethylated the promoters of metallothionein genes, resulting in decreased metallothionein expression leading to enhanced NF-κB activity. MiRNA-140-knockout mice were prone to hepatocarcinogenesis and had a phenotype similar to that of DDX20 deficiency, suggesting that miRNA-140 plays a central role in DDX20 deficiency-related pathogenesis. CONCLUSION These results indicate that miRNA-140 acts as a liver tumor suppressor, and that impairment of miRNA-140 function due to a deficiency of DDX20, a miRNA machinery component, could lead to hepatocarcinogenesis.

Abstract
BACKGROUND Ethanol injection is the best-known image-guided percutaneous ablation for hepatocellular carcinoma (HCC) and a well-tolerated, inexpensive procedure with few adverse effects. However, there have been few reports on its long-term results. AIMS We report a 20-year consecutive case series at a tertiary referral centre. METHODS We performed 2147 ethanol injection treatments on 685 primary HCC patients and analysed a collected database. RESULTS Final computed tomography demonstrated complete ablation of treated tumours in 2108 (98.2%) of the 2147 treatments. With a median follow-up of 51.6 months, 5-, 10- and 20-year survival rates were 49.0% [95% confidence interval (CI) = 45.3-53.0%], 17.9% (95% CI = 15.0-21.2%) and 7.2% (95% CI = 4..5-11.5%) respectively. Multivariate analysis demonstrated that age, Child-Pugh class, tumour size, tumour number and serum alpha-fetoprotein level were significant prognostic factors for survival. Five-, 10- and 20-year local tumour progression rates were 18.2% (95% CI = 15.0-21.4%), 18.4% (95% CI = 15.2-21.6%) and 18.4% (95% CI = 15.2-21.6%) respectively. Five-, 10- and 20-year distant recurrence rates were 53.5% (95% CI = 49.4-57.7%), 60.4 (95% CI = 56.3-64.5%) and 60.8% (95% CI = 56.7-64.9%) respectively. There were 45 complications (2.1%) and two deaths (0.09%). CONCLUSIONS Ethanol injection was potentially curative for HCC, resulting in survival for more than 20 years. This study suggests that new ablation therapies will achieve similar or even better long-term results in HCC.

Abstract
The "Guideline on the Use of New Anticancer Drugs for the Treatment of Hepatocellular Carcinoma" was prepared by the Study Group on New Liver Cancer Therapies established by the "Research Project on Emergency Measures to Overcome Hepatitis" under the auspices of the Health and Labour Sciences Research Grant. The Guideline brings together data collected by the Study Group on the use and incidence of adverse events in 264 patients with advanced hepatocellular carcinoma (HCC) treated using sorafenib and in 535 patients with advanced HCC treated using miriplatin at 16 participating institutions up until 22 December 2010, as well as referring to the published studies, academic presentations, and reports from the private sector. The aim of this Guideline is to facilitate understanding and current thinking regarding the proper usage of new anticancer drugs towards actual use in therapy. In terms of the format, the Guideline presents "clinical questions" on issues pertaining to medical care, makes "recommendations" on diagnosis and treatment in response to each of these clinical questions, and provides a rationale for these recommendations in the form of "scientific statements".

Abstract
BACKGROUND Patients with hepatocellular carcinoma (HCC) sometimes suffer from obscure gastrointestinal bleeding. Portal hypertension (PH), common in cirrhosis, induces esophagogastric varices. Because of the location, PH also may influence mucosal abnormalities in the small intestine. The objective of this study is to estimate the prevalence of small intestinal mucosal abnormalities in HCC patients using capsule endoscopy (CE). PATIENTS AND METHODS We prospectively conducted CE in HCC patients, and analyzed the findings in relation to hepatic function, the number and size of HCC tumor and findings obtained by conventional endoscopy. RESULTS Thirty-six patients (aged 66.7 ± 7.5 years, 29 men) underwent CE. Abnormal findings in the small bowel were found in 16 patients (44%), angioectasias in eight patients (22%), erosions in five (14%), varices in four (11%), polyps in four (11%), and submucosal tumor in one (3%). The patients with angioectasia had a larger spleen index than the no abnormal lesions group (85.4 ± 15.8 vs 59.0 ± 24.4, P = 0.02). The former group had been more frequently treated for esophageal varices endoscopically (62% vs 15%, P = 0.02). Large HCC nodules seemed more common in the patients with angioectasia than subjects without abnormal lesions (38% vs 5%, P = 0.06). Small intestinal varices also seemed to have a positive association with large HCC. During the follow up after CE, one patient with small intestinal polyps suffered from obscure gastrointestinal bleeding. CONCLUSIONS CE revealed that HCC patients frequently have small intestinal mucosal lesions. In particular, small intestinal angioectasia, which may cause obscure gastrointestinal bleeding, seems to be associated with portal hypertension.

Abstract
PURPOSE Sorafenib provides a survival benefit for patients with advanced hepatocellular carcinoma (HCC). However, there has been little experience with it in Japan. This study evaluated the safety and tolerance of sorafenib in Japanese patients with HCC. METHODS Clinical data for patients given sorafenib for advanced HCC were captured from eight institutions. All patients were classified as Child-Pugh A and the treatment was started at 400 mg twice daily. We recorded adverse events, treatment duration, and survival retrospectively. Adverse events were graded using Common Terminology Criteria, version 3.0; tumor response was assessed according to Response Evaluation Criteria in Solid Tumor, version 1.1. RESULTS Of the 54 patients treated, their median age was 69 years (range 48-82), 91% were males, 52% had HCV infection, and 22% had HBV infection. The most common drug-related adverse events were hand-foot skin reactions (HFSR) (72%), aspartate transaminase elevation (55%), alanine aminotransferase elevation (52%), rash (50%), fatigue (41%), and diarrhea (32%). Liver failure occurred in 19%. The median time to treatment failure was 2 months. Dose reduction was required in 83% of the patients, and this occurred within 2 weeks in 44%. The median overall survival was 6.9 months. CONCLUSIONS These data suggest that sorafenib is generally tolerated in Japanese patients with HCC. Nevertheless, the majority needed a dose reduction. Adverse events including HFSR, rash, and liver failure occurred more frequently in our patients than those reported elsewhere. Careful attention must be paid to these adverse events during sorafenib administration.

Abstract
BACKGROUND AND AIMS Ultrasonography is the most frequently used modality in surveillance for HCC among patients with chronic hepatitis C. However, the optimal surveillance interval is still controversial and the usefulness of supplementary tumor marker determination has not been confirmed. METHODS A total of 243 cases of naive HCC were detected among 1,431 patients with chronic hepatitis C under outpatient-based surveillance. The mode of HCC detection, including ultrasound surveillance interval, was retrospectively examined and the relation between the interval and detected tumor size was analyzed. Tumor volume doubling time was estimated from exponential increase in serum tumor marker levels when applicable. RESULTS HCC was first detected by ultrasonography in 221 patients. Ultrasound surveillance interval, ranging between 2 and 8 months, was not correlated with the size of tumor at detection. Patients with cirrhosis were likely to be surveyed at shorter intervals. The size of tumor exceeded 30 mm only in three (1.4%) cases. They were all positive for a biomarker and the estimated tumor doubling time was short. In 14 cases, HCC was first detected by CT indicated by abnormal rise in tumor marker levels despite negative ultrasound findings. In the remaining eight cases, ultrasonography had been replaced by CT as surveillance modality because of excessive obesity or coarseness of liver parenchyma. CONCLUSIONS Ultrasound surveillance at 6-month intervals was appropriate in general for the detection of HCC at a size smaller than 30 mm. However, in patient with established cirrhosis, more frequent screening would be needed to detect tumors of the same size.

Abstract
BACKGROUND Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is ordinarily indicated for those with three or fewer nodules, none of which exceeds 3 cm in diameter. This study investigated whether an apparent threshold exists in the diameter and number of nodules in terms of the prognosis of patients with HCC. METHODS We enrolled 663 naïve patients with HCC who were treated with RFA at our hospital between 1999 and 2005. We analyzed the patients' prognosis using multivariate Cox proportional regression with the diameter and number of nodules as covariates and Child-Pugh class as a stratification factor. The diameter and number were categorized as <or=2.0, 2.1-3.0, 3.1-4.0, 4.1-5.0, and >5 cm and 1, 2-3, 4-5, and >5, respectively. RESULTS The adjusted hazard ratio of patients whose largest nodule was <or=2.0, 2.1-3.0, 3.1-4.0, 4.1-5.0, and >5 cm was 1, 1.51, 2.56, 2.25, and 2.71, respectively. The adjusted hazard ratio of patients with one, two or three, four or five, and more than five nodules was 1, 1.35, 1.70, and 2.12, respectively. Therefore, patients with three or fewer nodules, none of which exceeds 5 cm in diameter, have a 5-year survival of 40%. CONCLUSIONS The prognosis of the patients worsened gradually as the diameter and number of nodules increased. No apparent threshold in the diameter or number of HCC nodules was detected. RFA can be applied beyond the conventional indications.

Abstract
BACKGROUND Neoplastic seeding reportedly occurs in up to 12.5% of patients treated with radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). The aim of this study is to assess the incidence, risk factors, and prognosis of neoplastic seeding after RFA among a large number of patients with a long-term follow-up. METHOD From February 1999 to December 2004, 1,031 patients underwent a total of 1,845 treatments with RFA for a total of 3,837 HCC nodules. The following variables were assessed to elucidate the risk factors of neoplastic seeding: age, sex, positivity for viral markers, tumor size, number of tumor nodules, number of RFA sessions, tumor location, percutaneous biopsy prior to RFA, alpha-fetoprotein (AFP), des-gamma-carboxy prothrombin (DCP) and lens culinaris agglutinin-reactive fraction of AFP (AFP-L3) levels, and the degree of tumor differentiation. RESULTS Neoplastic seeding was detected in 33 patients (3.2% per patient) at intervals of 4.8-63.8 (median, 15.2) months after RFA. On multivariate logistic regression analysis, only the poor differentiation degree was associated with the risk of neoplastic seeding (P= 0.012). Of tumor factors, tumor size, and AFP, DCP, and AFP-L3 levels were significantly associated with the poor differentiation degree. The cumulative survival rates 1 and 2 yr after the detection of neoplastic seeding were 86% and 47%, respectively. CONCLUSION Poor differentiation degree was the risk factor of neoplastic seeding after RFA for HCC. The surrogate markers for poor differentiation degree were larger tumor size and elevated tumor marker levels. Indication for RFA should be carefully considered for HCC patients under these conditions.

Abstract
BACKGROUND Extrahepatic metastasis of hepatocellular carcinoma (HCC) is of growing importance as the survival of patients has been improved owing to advances in treatments to intrahepatic lesions. METHODS To elucidate the incidence and risk factors of extrahepatic metastasis of HCC, we enrolled 1573 (1131 treatment-naïve and 442 previously treated on referral) patients with HCC without extrahepatic tumour spread treated at the authors' department between 1990 and 2003. Patients received medical treatment including percutaneous ablation and transcatheter arterial chemoembolization, and followed by dynamic computed tomography (CT) or magnetic resonance imaging (MRI) and tumour markers every 3-4 months. Extrahepatic metastasis was diagnosed by plain X-ray, CT, MRI and scintigraphy. Clinical parameters at the time of treatment to intrahepatic lesions were evaluated as a predictor of subsequent extrahepatic metastasis among the 1131 treatment-naïve patients by Cox's proportional hazard model. RESULTS During the average observation period of 3.9 years, extrahepatic metastasis was diagnosed in 123 in the treatment-naïve and 53 in the patients treated previously. The incidence rate of extrahepatic metastasis, as detected during the lifetime after medical treatment of HCC, was approximately 13% at 5 years. Multivariate analysis with Cox proportional hazard model revealed that positivity for viral markers, lager tumour diameter, multiple tumour nodules, presence of vascular tumour invasion and elevated tumour markers were associated with the development of extrahepatic metastasis. CONCLUSION The incidence of extrahepatic metastasis of HCC diagnosed during clinical course was not frequent. Advanced intrahepatic lesions, presence of vascular tumour invasion, elevated tumour markers and presence of viral hepatitis were risk factors for extrahepatic metastasis.

Abstract
BACKGROUND Overweight and hepatic steatosis can increase the risk of hepatocarcinogenesis. In addition, overweight may affect the treatment efficacy of ultrasound-guided percutaneous ablation. We evaluated the impact of overweight on the safety and efficacy of percutaneous ablation to hepatocellular carcinoma (HCC). METHODS We enrolled 743 patients with naïve HCC who were treated by percutaneous ablation including ethanol injection, microwave coagulation, and radiofrequency ablation (RFA) between 1995 and 2003. Patients were divided into two groups by body mass index (BMI): 219 overweight patients with BMI>25 kg/m2 and 524 control patients with BMI<or=25 kg/m2. The effects of BMI on complications of percutaneous ablation, HCC recurrence, and overall survival were analyzed, together with others including tumor and liver function-related factors. RESULTS The overweight group required a significantly larger number of sessions by RFA (P=0.01). Major complications were identified in 8.7% in the overweight group and 7.6% in the control group (P=0.94). There was no significant difference in cumulative recurrence rate and local tumor-progression rate between the two groups (P=0.63 and 0.44). Cumulative survival rates at 1, 3, and 5 years were 95.4%, 75.7%, and 57.8%, respectively, in the overweight group and 94.1%, 78.0%, and 58.8% in the control group (P=0.99). CONCLUSIONS The results indicated that overweight did not increase complications nor affect HCC recurrence and overall survival. However, the number of sessions of RFA was significantly greater in overweight patients, suggesting that overweight was associated with minor technical difficulties.

Abstract
Three tumor markers for hepatocellular carcinoma (HCC) are available in daily practice in Japan: alpha-fetoprotein (AFP), des-gamma-carboxy prothrombin (DCP), and lens culinaris agglutinin-reactive fraction of alpha-fetoprotein (AFP-L3). To elucidate the predictability of these tumor markers on HCC recurrence after curative ablation, we enrolled 416 consecutive patients with naïve HCC who had been treated by percutaneous ablation at our department from July 1997 to December 2002. Tumor marker levels were determined immediately before and 2 months after the treatment. Complete ablation was defined on CT findings as nonenhancement in the entire lesion with a safety margin. Tumor recurrence was also defined as newly developed lesions on CT that showed hyperattenuation in the arterial phase with washout in the late phase. We assessed the predictability of recurrence via tumor markers in multivariate analysis, using proportional hazard regression after adjusting for other significant factors in univariate analysis. Until the end of follow-up, tumor recurrence was identified in 277 patients. Univariate analysis revealed the following factors to be significant for recurrence: platelet count; size and number of tumors; AFP, AFP-L3, and DCP preablation; and AFP and AFP-L3 postablation. Multivariate analysis indicated that AFP >100 ng/mL and AFP-L3 >15%, both pre- and postablation, were significant predictors. The positivity of AFP and AFP-L3 preablation that turned negative postablation was not significant. In conclusion, tumor markers pre- and post-ablation were significant predictors for HCC recurrence and can complement imaging modalities in the evaluation of treatment efficacy.

Abstract
BACKGROUND/AIMS It is not known whether the putative etiologic factors and clinical and pathological features of hepatocellular carcinoma differ between young adults and older patients. Therefore this study aims to evaluate whether the clinicopathological features in young patients with HCC significantly differ from those of elderly patients. METHODOLOGY A total of 1014 consecutive patients with HCC were divided into two groups based on age. Among them, 73 patients younger than 50 years of age comprised the first group and 941 patients 50 years and older made up the second. Clinical, laboratory, and pathological characteristics were compared between the two age groups. RESULTS The male: female ratio and the incidence of positive hepatitis B surface antigen were significantly higher in young patients than in elderly patients. Tumor size, pathological grading of the tumor, and the severity of liver disease did not differ between the two groups. Especially in those patients demonstrating positive antibody to hepatitis C virus, alanine aminotransferase was higher in the younger, and platelet count was lower. Younger patients also had a higher ratio of alcohol consumption compared to elderly patients. CONCLUSIONS There were age-related differences in the clinicopathological characteristics of HCC patients. Concerning hepatocarcinogenesis, male and HBsAg positive patients were at high risk in young. Of the HCV-related HCC patients, heavy drinking may accelerate the progression from chronic hepatitis to cirrhosis and HCC.
