    Hepatocellular carcinoma (HCC) is the fifth most common neoplasm and the third leading cause of cancer-related deaths worldwide. Cirrhosis, most often due to viral hepatitis, is the predominant risk factors for HCC and geographical differences in both risk factors and incidence are largely due to epidemiological variations in hepatitis B and C infection. Hepatic function is a relevant parameter in selecting therapy in HCC. The current clinical classification of HCC split patients into 5 stages, with a specific treatment schedule for any stage. As patients with early stages can receive curative treatments, such as surgical resection, liver transplantation or local ablation, surveillance program in high-risk populations has become mandatory. Sorafenib, a multikinase inhibitor, has recently shown survival benefits in patients at advanced stage of disease. Hopefully, new molecular targeted therapies and their combination with sorafenib or interventional and surgical procedures, should expand the therapeutic armamentarium against HCC.

    Hepatocellular carcinoma (HCC) is frequently diagnosed at advanced stages and has a high mortality rate. With improved survival of patients with cirrhotic liver disease and increased prevalence of chronic hepatitis C viral infections, a rise in the number of HCC cases is being reported worldwide. Early diagnosis and treatment can significantly improve the prognosis of patients with HCC. Although surgical resection is an important potentially curative therapy for liver tumors, in appropriately selected patients, liver transplantation has been shown to achieve excellent survival rates for a solid tumor. Locally ablative and locoregional therapies in the form of percutaneous ethanol injection, radiofrequency ablation, transcatheter arterial chemoembolization and transcatheter arterial radioembolization (TheraSphere) are viable options in patients with unresectable HCC. Unfortunately, the role of systemic therapy has been very limited in the treatment of these patients. Novel treatment options based on an improved understanding of the molecular pathogenesis of HCC are being explored. These targeted molecular therapies are aimed at growth factors and their receptors, intracellular signal transduction and cell cycle control. A substantial improvement in outcomes of intermediate and advanced stage HCC is expected with the advent of these targeted therapies, used in combination with surgical or locoregional therapies. Recent positive results from a large Phase III study of the receptor tyrosine kinase inhibitor, sorafenib, hold great promise in the treatment of HCC.

    Hepatocellular carcinoma (HCC) is a major cause of cancer-related death worldwide. In select patients, surgical treatment in the form of either resection or transplantation offers a curative option. The aims of this review are to (1) review the current American Association for the Study of Liver Diseases/European Association for the Study of the Liver guidelines on the surgical management of HCC and (2) review the proposed changes to these guidelines and analyze the strength of evidence underlying these proposals. Three authors identified the most relevant publications in the literature on liver resection and transplantation for HCC and analyzed the strength of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) classification. In the United States, the liver allocation system provides priority for liver transplantation to patients with HCC within the Milan criteria. Current evidence suggests that liver transplantation may also be indicated in certain patient groups beyond Milan criteria, such as pediatric patients with large tumor burden or adult patients who are successfully downstaged. Patients with no underlying liver disease may also benefit from liver transplantation if the HCC is unresectable. In patients with no or minimal (compensated) liver disease and solitary HCC ≥2 cm, liver resection is warranted. If liver transplantation is not available or contraindicated, liver resection can be offered to patients with multinodular HCC, provided that the underlying liver disease is not decompensated. Many patients may benefit from surgical strategies adapted to local resources and policies (hepatitis B prevalence, organ availability, etc). Although current low-quality evidence shows better overall survival with aggressive surgical strategies, this approach is limited to select patients. Larger and well-designed prospective studies are needed to better define the benefits and limits of such approach. PMID:28975836

    This article presents a review of the literature regarding the use of transcatheter arterial chemoembolization (TACE) in the treatment of hepatocellular carcinoma (HCC). There have been two different approaches to the treatment: (a) percutaneous tumor ablation methods which can be divided into injectable and thermal methods; percutaneous ethanol injection (PEI) is the most widely used method, and (b) TACE. PEI is the treatment of choice for single HCCs smaller or equal to 3 cm in size. For patients with large HCCs combined TACE and PEI is probably the most effective nonsurgical treatment. In the presence of multiple HCC nodules, TACE remains the treatment of choice

    Hepatocellular carcinoma (HCC) is a common cause of cancer mortality. Hepatitis B and C viruses, aflatoxin and alga toxin in the contaminated drinking water are the major etiological factors. Rapidly progressing medical imaging has resulted in the improved treatment results. Surgical resection has a major role for influencing prognosis of HCC. Local cancer therapies based on the advances in early diagnosis are progressing rapidly. Multimodality combination and sequential treatment has proved effective, unfortunately systemic chemotherapy for HCC remains disappointed. All of these have resulted in the improved prognosis of HCC.

    Objective: To show the computed tomography (CT) usefulness after treatment with transcatheter arterial quimioembolization and radiofrequency ablation of hepatocellular carcinoma. Material and methods: In a period between march 2006 to april 2008 a total of 90 patient presenting 148 nodular lesions with diagnosis of hepatocellular carcinoma were controlled with triphasic CT. All the lesions were treated with minimally invasive procedure. For the treatment, the patients were classified in two groups following Milan criteria. The first group, constituted by 75 patients with 109 nodules, was treated with quimioembolization. The second group, of 15 patients with 25 nodules, was treated with radiofrequency ablation. In our population, a subgroup of 10 patients was treated with both methods. Results: Of 90 patients after CT control on a month, 3 months and for each 3 months during 2 years, on 63 cases (70%) was observed homogeneous accumulation of iodized oil, partial defect without enhancement or absence of enhancement on treated lesions. In these patients a new treatment after initial one was not performed. The remaining 27 patients (30%) underwent new treatment because we founded partial defect or absence of iodized oil with enhancement or peripheral enhancement on arterial phase in treated lesions. In this last group, 16 treated patients (17.7%) had new nodular enhancement on the remaining hepatic parenquimal. Conclusion: The CT unenhanced and the arterial phase on a month and for each 3 months, allow monitoring the effectiveness, residual disease and/or relapse of hepatocellular carcinoma after minimally invasive treatment.

    Unresectable hepatocellular carcinoma is extremely difficult to treat. TheraSphere consists of yttrium-90 (a pure beta emitter) microspheres, which are injected into the hepatic arteries. This article reviews the safety and survival of patients with hepatocellular carcinoma who were treated with yttrium-90 microspheres. Eighty patients were selected from a database of 108 yttrium-90 microsphere-treated patients and were staged by using Child-Pugh, Okuda, and Cancer of the Liver Italian Program scoring systems. Patients were treated with local, regional, and whole-liver approaches. Survival from first treatment was analyzed with Kaplan-Meier and Cox regression methods. Adverse events and complications of treatment were coded by using the Southwest Oncology Group toxicity scoring system. Patients received liver doses ranging from 47 to 270 Gy. Thirty-two patients (40%) received more than 1 treatment. Survival correlated with pretreatment Cancer of the Liver Italian Program scores ( P = .002), as well as with the individual Cancer of the Liver Italian Program components, Child-Pugh class, alpha-fetoprotein levels, and percentage of tumor replacement. Patients classified as Okuda stage I (n = 54) and II (n = 26) had median survival durations and 1-year survival rates of 628 days and 63%, and 384 days and 51%, respectively ( P = .02). One patient died of liver failure judged as possibly related to treatment. Thus, in selected patients with hepatocellular carcinoma, yttrium-90 microsphere treatment is safe and well tolerated. On the basis of these results, a randomized controlled trial is warranted comparing yttrium-90 microsphere treatment with transarterial chemoembolization by using the Cancer of the Liver Italian Program system for prospective stratified randomization.

    Full Text Available Hepatocellular carcinoma (HCC is the most common malignant liver tumor, and there are limited systemic treatments for patients with advanced HCC. Regorafenib is an oral multi-kinase inhibitor, and phase III clinical trial has shown that regorafenib can significantly extend the median survival of patients with advanced HCC by 2.8 months, which makes it a second-line drug approved by FDA for the treatment of advanced HCC, just after sorafenib. This article reviews the basic and clinical research on regorafenib in the field of HCC.

    A small percentage of patients with hepatocellular carcinoma (HCC) are candidates for curative treatment in form of resection or transplantation. There are different treatment options for unresectable HCC-like local ablative therapies and recently systemic therapy with Sorafenib. All of these have variable response rate and had been proven to improve survival. In the last few years, there is a growing interest in TheraSphere radioembolization. It consists of yttrium90 (Y-90) embedded into nonbiodegradable glass microspheres. It is selectively administered by intraarterial hepatic injection giving high doses of radiation to the tumor and sparing the liver parenchyma. It has been shown to improve survival and used as a bridge to transplantation and to downstage tumors for resection. Therasphere seems to have favorable safety profile and has been used in patients with portal vein thrombosis with successful outcome.

  13. ANGIOGENESIS INHIBITORS FOR THE TREATMENT OF HEPATOCELLULAR CARCINOMA

    2016-11-01

    Full Text Available Background: Angiogenesis inhibitors have become an important therapeutic approach in the treatment of hepatocellular carcinoma (HCC patients. The achievement of Sorafenib in prolonging overall survival of patients with HCC makes therapeutic inhibition of angiogenesis a fundamental element of the treatment of HCC. Considering the heterogeneous aspects of HCC and to enhance therapeutic efficacy, overcome drug resistance and reduce toxicity, the combination of antiangiogenic drugs with antiblastic chemotherapy (AC, radiotherapy or other targeted drugs have been evaluated. The issue is further complicated by the combination of antiangiogenesis with other AC or biologic drugs. To date, there is no planned approach to determine which patients are more responsive to a given type of antiangiogenic treatment. Conclusion: Large investments in the clinical research are essential to improve treatment response and minimize toxicities for patients with HCC. Future investigations will need to focus on utilizing patterns of genetic information to classify HCC into groups that display similar prognosis and treatment sensitivity, and combining targeted therapies with AC producing enhanced anti-tumor effect. In this review the current panel of available antiangiogenic therapies for the treatment of HCC have been analyzed. In addition current clinical trials are also reported herein.

  14. Value of radiofrequency ablation in the treatment of hepatocellular carcinoma

    Hepatocellular carcinoma (HCC) is a malignant disease that substantially affects public health worldwide. It is especially prevalent in east Asia and sub-Saharan Africa, where the main etiology is the endemic status of chronic hepatitis B. Effective treatments with curative intent for early HCC include liver transplantation, liver resection (LR), and radiofrequency ablation (RFA). RFA has become the most widely used local thermal ablation method in recent years because of its technical ease, safety, satisfactory local tumor control, and minimally invasive nature. This technique has also emerged as an important treatment strategy for HCC in recent years. RFA, liver transplantation, and hepatectomy can be complementary to one another in the treatment of HCC, and the outcome benefits have been demonstrated by numerous clinical studies. As a pretransplantation bridge therapy, RFA extends the average waiting time without increasing the risk of dropout or death. In contrast to LR, RFA causes almost no intra-abdominal adhesion, thus producing favorable conditions for subsequent liver transplantation. Many studies have demonstrated mutual interactions between RFA and hepatectomy, effectively expanding the operative indications for patients with HCC and enhancing the efficacy of these approaches. However, treated tumor tissue remains within the body after RFA, and residual tumors or satellite nodules can limit the effectiveness of this treatment. Therefore, future research should focus on this issue. PMID:24876721

    Purpose. The comparative efficacy of transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) in the treatment of hepatocellular carcinoma (HCC) was investigated. Methods. Two hundred and sixty consecutive patients were retrospectively analyzed: 156 had received between one and six chemoembolization sessions at 3-month intervals, 33 had had PEI, and the remaining 71 patients refused any treatment. The follow-up ranged from 3 to 36 months. Survival rates were statistically analyzed by life-table analysis. Results. Patients' survival was affected by the number of nodules and by the Child's and Okuda's classes; no relationship was found between survival rates and the histologic grade or vascular supply of the tumor. In the case of a single lesion of Okuda's class I, TACE was more effective than PEI. In multifocal HCC, TACE was better than no treatment in Okuda's class I and Child's class A. Conclusion. We suggest TACE as the treatment of choice in Child A or Okuda I patients with multifocal HCCs; it seems of little help in Child B-C or Okuda II-III patients

    Sorafenib is the standard of care for patients with advanced hepatocellular carcinoma (HCC) and well preserved liver function. However, until recent approval of regorafenib by the Food and Drug Administration (FDA), no effective therapeutic options were available for patients resistant to sorafenib. Areas covered: The present article reviews the preclinical and clinical data of regorafenib, putting them into the context of current and future landscape of treatment options for patients with HCC. Recently, the randomized, placebo-controlled, Phase III RESORCE trial, demonstrated a statistically and clinically significant increase in overall survival from 7.8 months with placebo to 10.6 months with regorafenib in patients progressing on sorafenib. Furthermore, the study showed a significant improvement in all the other efficacy endpoints. Main adverse events were hypertension, hand-foot skin reaction, fatigue and diarrhea, with no negative impact on quality of life. Expert commentary: Regorafenib is a recently approved treatment option for HCC patients who have been previously treated with sorafenib. The RESORCE trial demonstrates the beneficial effect of a sequential approach involving two multikinase inhibitors, namely sorafenib and regorafenib, whose antitumor activity extends beyond their antiangiogenic functions.

  17. Improving clinical trial design for hepatocellular carcinoma treatments

    Full Text Available Despite its place as the third leading cause of cancer deaths worldwide, there are currently no approved chemotherapeutic agents, devices or techniques to treat hepatocellular carcinoma. Importantly, there have been no phase III studies demonstrating survival benefit, nor any randomized studies of treatment except for transarterial chemoembolization and most recently sorafenib. The importance of well-designed clinical trials of agents to treat HCC has never been greater. However, general clinical study design issues, combined with HCC-specific issues pose significant challenges in structuring such studies. HCC-related challenges include the heterogeneity of this cancer and the fact that it is frequently accompanied by significant comorbidities at diagnosis, such as active hepatitis B or C virus replication, substantial past or on-going alcohol use, and cirrhosis, itself often a fatal disease. The recently published comparison of a newer treatment, nolatrexed to doxorubicin, and comments about this study’s initial HCC diagnostic criteria, staging system, comparator therapy and choice of endpoints have provided a platform to discuss the challenges unique to the design of HCC clinical trials. The difficulty in accurately framing study results obtained from the constantly changing HCC clinical landscape and approaches to meet these challenges will be reviewed.

    Hepatocellular carcinoma (HCC) is one of the most common malignancies leading to high mortality rates in the general population; in cirrhotic patients, it is the primary cause of death. The diagnosis is usually delayed in spite of at-risk population screening recommendations, i.e., patients infected with hepatitis B or C virus. Hepatocarcinogenesis hinges on a great number of genetic and molecular abnormalities that lead to tumor angiogenesis and foster their dissemination potential. The diagnosis is mainly based on imaging studies such as computed tomography and magnetic resonance, in which lesions present a characteristic classical pattern of early arterial enhancement followed by contrast medium “washout” in late venous phase. On occasion, when imaging studies are not conclusive, biopsy of the lesion must be performed to establish the diagnosis. The Barcelona Clinic Liver Cancer staging method is the most frequently used worldwide and recommended by the international guidelines of HCC management. Currently available treatments include tumor resection, liver transplant, sorafenib and loco-regional therapies (alcoholization, radiofrequency ablation, chemoembolization). The prognosis of hepatocarcinoma is determined according to the lesion’s stage and in cirrhotic patients, on residual liver function. Curative treatments, such as liver transplant, are sought in patients diagnosed in early stages; patients in more advanced stages, were not greatly benefitted by chemotherapy in terms of survival until the advent of target molecules such as sorafenib.

    We report our institutional observations of ten patients with advanced hepatocellular carcinoma (HCC) (seven and three were Child-Pugh class A and B, respectively) who received compassionate regorafenib therapy between June 2016 and January 2017. These patients did not fit the rigid criteria of a clinical trial and represented the use of regorafenib in an everyday clinic situation. Regorafenib (160 mg P.O. daily) was administered to patients on a 4-week cycle (3 weeks on, 1 week off) until disease progression (assessed using mRECIST criteria) or discontinuation secondary to toxicity (assessed using CTCAE criteria). Relevant clinical data were abstracted from patient medical records and reviewed retrospectively. The median duration of patient treatment was 6.6 weeks, and the median time to disease progression was 12.5 weeks. Most common treatment emergent adverse events were fatigue, diarrhea, and hand-foot skin reaction. Elevated AST and ALT were the most commonly observed laboratory-assessed adverse events, which reached grade 3 status in the Child-Pugh class B patients only. We observed intolerance to regorafenib treatment in one patient who had previously received a liver transplant. We also saw lithium toxicity in one patient receiving long-term lithium treatment, suggesting a potential and unexpected drug-drug interaction with regorafenib. Taken together, our observations indicate that regorafenib is beneficial in the treatment of patients with advanced HCC who progressed on or demonstrated intolerance to sorafenib therapy; however, careful selection and close monitoring of patients is necessary to maximize the benefit while minimizing the toxicities of regorafenib treatment.

    Hepatocellular carcinoma (HCC) is ranked as the 5th common type of cancer worldwide and is considered as the 3rd common reason for cancer-related deaths. HCC often occurs on top of a cirrhotic liver. The prognosis is determined by several factors; tumour extension, alpha-fetoprotein (AFP) concentration, histologic subtype of the tumour, degree of liver dysfunction, and the patient’s performance status. HCC prognosis is strongly correlated with diagnostic delay. To date, no ideal screening modality has been developed. Analysis of recent studies showed that AFP assessment lacks adequate sensitivity and specificity for effective surveillance and diagnosis. Many tumour markers have been tested in clinical trials without progressing to routine use in clinical practice. Thus, surveillance is still based on ultrasound (US) examination every 6 mo. Imaging studies for diagnosis of HCC can fall into one of two main categories: routine non-invasive studies such as US, computed tomography (CT), and magnetic resonance imaging, and more specialized invasive techniques including CT during hepatic arteriography and CT arterial portography in addition to the conventional hepatic angiography. This article provides an overview and spotlight on the different diagnostic modalities and treatment options of HCC. PMID:26140083

    The frequency with which patients in Child-Pugh B having hepatocellular carcinoma are treated following the international guidelines according to the Barcelona Clinic Liver Cancer stages is unknown. To investigate treatment allocation for Child-Pugh B patients in different tumour stages, with particular interest in the intermediate stage. Patients were retrospectively identified from a consecutively collected series. Treatment was carried out primarily according to the guidelines. Of 86 Child-Pugh B patients, 45 were Barcelona early stage, of which the Child-Pugh scores were 46.7% B7, 33.3% B8, 20.0% B9; 27 patients were intermediate stage (B7 59.3%, B8 37.0% and B9 3.7% respectively), 12 were advanced (41.7% B7, 25.0% B8 and 33.3% B9) and 2 were terminal (both B9). In the intermediate stage, transarterial chemoembolization (or ablation) was performed in 68.8% of the Child-Pugh B7 patients, 50% of the B8 patients and 0% of the B9 patients. Median survival of the intermediate patients was 8.0 months (9.0 in B7 vs. 6.0 in -B8/B9, P=0.048). Survival of the intermediate stage patients undergoing chemoembolisation was 22.0 months in Child-Pugh B7 and 6.0 in B8. Approximately half of the intermediate stage patients can undergo locoregional treatment with good survival when in the Child-Pugh B7. The Child-Pugh numeric score impacts survival, suggesting that this tumour stage be refined. Copyright © 2013 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

    The aim of the present study was to evaluate the outcomes of a multimodal treatment approach of hepatocellular carcinoma (HCC) in a tertiary hepatobiliary specialty center. A total of 294 consecutive patients treated for HCC were retrospectively analyzed. Two hundred sixteen patients (73.4%) were men and 78 (26.6%) were women. Liver resection (LR) was performed in 201 patients (68.4%), liver transplantation (LT) in 19 patients (6.5%), radiofrequency ablation (RFA) in 74 patients (25.1%), and 56 (19%) patients received adjuvant systemic chemotherapy. The median follow-up was 15.7 mo (range 0.1-90.3). Five-year overall survival and recurrence rates were 28% and 26.8%, respectively. Serum AFP > 43.8ng/ml (p = 0.005), BCLC C/D (p = 0.006) and JIS 3/4/5 classifications (p = 0.02) were independent negative prognostic factors for overall survival, while JIS 3/4/5 (p = 0.01) and BCLC C/D (p = 0.01) classifications, tumors larger than 6.5cm (p = 0.001) and RFA (p = 0.02) were independent predictors for recurrence. The current treatment of HCC should be multimodal, and therapeutic modalities and their combinations should be tailored to each patient. LT represents the best therapeutic option for patients with HCC in the setting of cirrhosis. Resection remains a good option in cirrhotic patients, while RFA is a safe and effective procedure for small tumors.

  3. Trends and practices in diagnosis and treatment of hepatocellular carcinoma

    International Nuclear Information System (INIS)

    2010-01-01

    Hepatocellular carcinoma (HCC), or primary liver cancer, is one of the most common causes of cancer and cancer death globally, and has an increasing incidence. It is currently the fifth most common cancer among men and eighth among women. In some Asian and African countries, its incidence is similar to that of lung cancer. It carries a very poor prognosis; the majority of patients die within a year, making it the third most common cause of cancer death. Currently, the main treatments offering the chance of cure are surgical resection and liver transplantation. However, owing to late presentation and underlying liver cirrhosis, these are suitable only for a small minority of patients. Therefore, new investigative protocols in radiotherapy using the most advanced technologies have been developed with some promise of cure and effective palliation. However, no uniform recommendations exist and the use of radiotherapy is limited by pre-existing liver disease. The IAEA has extensive projects in radiation oncology in low and middle income countries, including areas in Asia and Africa where HCC is a common problem. Since there has been a reported significant increase in the use of radiotherapy in HCC, an expert review was considered timely to assess the role of radiotherapy within the entire framework of HCC management. This publication developed from the need to address this issue. A meeting on the current knowledge of HCC epidemiology and management protocols was convened in October 2008. The given task was to define the current role of radiotherapy in the management of HCC. The greatest number of patients requiring optimal management protocols for HCC lives in Asia and sub-Saharan Africa, where in many countries access to radiotherapy and cancer care in general is limited and resources for research and access to the most advanced technologies are not available. This review is intended for use in training courses and as a source of information on treatment decisions. It

    Background/Aim: The therapeutic effect of intra-arterial injection of 131-iodine-labeled lipiodol for treatment of hepatocellular carcinoma in palliative or adjuvant settings has been promising. We report, the results of an open study of this therapy in cirrhotic patients with small hepatocellular carcinoma. Patients and method: Forty patients with hepatocellular carcinoma were given intra-arterial injections of 131-iodine-labeled lipiodol. These injections were repeated if necessary every 3 months. Tumor response (WHO criteria) was determined on CT scans performed after each treatment and every 3 months during the follow-up. Side effects and the cause of death were recorded. Therapeutic response and survival were analyzed. Results: The median number of treatment was 2 (1-4). There was one complete response, 18 partial responses (47.5% response rate); 19 had stable disease and 2 progressions. Overall survival rates (±CI 95%) at 1, 2 and 3 years were: 90 ± 4.7%, 60.3 ± 8%, and 39 ± 8.3%, respectively. Median survival was 27 months; 25 patients have died (4-56 months), 8 of tumor progression with a multifocal spread in the liver. Tolerance was good except for 2 patients who develop a fatal drug-related pulmonary insufficiency. Conclusion: These data suggest that intra-arterial therapeutic injection of 131-iodine-labeled lipiodol for treatment of hepatocellular carcinoma can provide high rate response and long survival for individuals not eligible for surgery or local treatment

    Full Text Available Hepatocellular carcinomas are highly vascular tumors, showing progressive hypervascularity by the process of neoangiogenesis. Tumor angiogenesis is critical for tumor growth as well as metastatic spread therefore, imaging and quantification of tumor neo-angiogenesis is essential for monitoring response to targeted therapies and predicting disease progression. Sorafenib is a molecular targeting agent used for treating hypervascular tumors. This drug is now the standard of care in treatment of patients with advanced hepatocellular carcinoma. Due to its anti-angiogenic and anti-proliferative actions, imaging findings following treatment with Sorafenib are quite distinct when compared to conventional chemotherapeutic agents. Liver MRI is a widely adopted imaging modality for assessing treatment response in hepatocellular carcinoma and imaging features may reflect pathophysiological changes within the tumor. In this mini-review, we will discuss MRI findings after Sorafenib treatment in hepatocellular carcinoma and review the feasibility of MRI as an early biomarker in differentiating responders from non-responders after treatment with molecular targeting agents.

    The frequency of hepatocellular carcinoma (HCC) is increasing in the western world and the role of radiotherapy is more and more discussed. Classically, hepatocellular carcinoma was considered as a radioresistant tumour: in fact, modern radio-biologic studies, performed on cell lines directly established from patients, showed that hepatocellular carcinoma has the same radiosensitivity than the other epithelial tumours. From clinical studies, its α/β ratio has been estimated to be around 15 Gy. Radiosensitivity of normal hepatic parenchyma is now well evaluated and some accurate NTCP models are available to guide hepatic irradiation. The biology of hepatocellular carcinoma is also better described: the combination of radiotherapy and targeted therapies will be a promising approach in the near future. (authors)

    Yttrium-90 microspheres are radioactive particles which are increasingly being employed for treating patients with unresectable hepatocellular carcinoma (HCC). The procedure is called radioembolization. It involves the injection of micron-sized embolic particles loaded with a radioisotope by use of transarterial techniques. Because of the sensitivity of liver parenchyma and relative insensitivity of tumor, external radiation has played a limited role in treating HCC. (90)Y administered via arterial route directs the highly concentrated radiation to the tumor while healthy liver parenchyma is relatively spared due to its preferential blood supply from portal venous blood. This technique has proven useful for the majority of patients with HCC as most of them present in advanced stage, beyond potentially curative options (resection/liver transplantation). (90)Y microspheres can be used in downstaging large tumors to bring within transplantable criteria, in patients with portal venous thrombosis due to tumor invasion and as palliative therapy. There are two available devices for (90)Y administration; TheraSphere® (glass based) and SIR-Spheres® (resin based). The procedure is performed on an outpatient basis. The incidence of complications is comparatively less and may include nausea, fatigue, abdominal pain, hepatic dysfunction, biliary injury, fibrosis, radiation pneumonitis, GI ulcers, and vascular injury; however, these can be avoided by meticulous pretreatment assessment, careful patient selection, and adequate dosimetry. This article explores the technical and clinical aspects of (90)Y radioembolization with keeping emphasis on patient selection, uses, and complications.

    Objective: To analyze the efficacy, side effects and complications of percutaneous high frequency induced thermotherapy (HiTT) performed under CT guidance involving 36 patients with hepatocellular carcinomas (HCC) and hepatic metastatic lesions. Methods: HiTT was performed in treatment of 36 patients (24 men and 12 women) with 42 hepatocellular carcinoma and hepatic metastatic carcinoma (six patient out of 36 had two nidi). The diameter of the tumors ranged from 1.6 to 7.8 cm (mean, 3.2 cm). The efficacy of HiTT was evaluated with triphasic spiral CT performed 1 month after the procedure. Results: The post-treatment CT scan showed complete necrosis in 33 nidi (78%) out of 42 nidi of hepatocellular carcinoma and hepatic metastatic carcinoma in 30 patients out of 36. Complete necrosis was obtained in 18 (95%) of 19 tumors no larger than 3 cm in diameter, 13 (72%) of 18 tumors between 3.0 and 5.0 cm in diameter. Eleven tumors showed incomplete necrosis. In our study, none of the patients experienced severe complications. All the patients are alive in the follow-up ranging from 2 to 12 months (mean, 7 months). Conclusion: Our research suggests that HiTT can be a safe and effective treatment of hepatocellular carcinomas and hepatic metastatic carcinoma when the lesion is no larger than 3 cm. The treatment is relatively effective for hepatocellular carcinoma between 3 and 5 cm in size. (authors)

    The purpose of this study is to evaluate the therapeutic efficacy of intra-arterial infusion of Cis-diamminedichloroplatinum (C-DDP) for the treatment of hepatocellular carcinomas with widespread involvement. We retrospectively analyzed 22 patients who between July 1994 and June 1996 had undergone intra-arterial c-DDP infusion therapy for the treatment of hepatocellular carcinomas with widespread involvement. The hepatomas involved both lobes in ten, portal venous obstructions in fourteen, arterio-portal shunts in nine, and arterio-venous shunts in two. Proper hepatic artery was selected for infusion of 100 mg/BSA of C-DDP. The same procedure was repeated every 3 to 4 weeks, and the total number of infusions was 65. On the basis of WHO criteria, response was classified as complete remission, partial remission, stable, or progression of the disease. Six-month and one-year survival rates were estimated, and adverse reactions were evaluated. Although the response rate is not high, intra-arterial C-DDP infusion therapy can be used as an alternative treatment for hepatocellular carcinomas with widespread involvement; adverse reactions are tolerable.

    Full Text Available ABSTRACT Hepatocellular carcinoma is a malignancy of global importance and is associated with a high rate of mortality. Recent advances in the diagnosis and treatment of this disease make it imperative to update the recommendations on the management of the disease. In order to draw evidence-based recommendations concering the diagnosis and management of hepatocellular carcinoma, the Brazilian Society of Hepatology has sponsored a single-topic meeting in João Pessoa (PB. All the invited pannelists were asked to make a systematic review of the literature and to present topics related to the risk factors for its development, methods of screening, radiological diagnosis, staging systems, curative and palliative treatments and hepatocellular carcinoma in noncirrhotic liver. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of those recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present paper is the final version of the reviewed manuscript containing the recommendations of the Brazilian Society of Hepatology.

Currently available curative options, such as surgery and transplantation, are not available to patients with advanced stages of disease. Among the potential new treatments being investigated are microRNA (miRNA-based therapies. A number of preclinical studies have reported antitumor activities of miRNA mimics or anti-miRNA molecules. Optimal in vivo delivery of miRNA molecules is crucial to their action. To this end, significant progress has been made in the development of nanoparticles for in vivo delivery of miRNA molecules. Delivery of these molecules, alone or in combination with other drugs, promises to open new possibilities for therapeutic approaches to hepatocellular carcinoma.

    We investigated the contribution of subsequent therapy for advanced hepatocellular carcinoma refractory or intolerant to sorafenib. Further, we investigated the impact of sorafenib on overall survival using individual data. We reviewed the medical records of patients with advanced hepatocellular carcinoma treated with sorafenib. Survival after sorafenib treatment and overall survival were defined as the time when we discovered that patients were either refractory or intolerant to sorafenib and the period from the start of sorafenib treatment, respectively, until death during the study. We compared patients’ prognoses according to their subsequent treatment as follows: group A, therapies targeting intrahepatic lesions; group B, systemic therapies alone; group C, no subsequent therapy. We used linear regression analysis to determine whether there was an association with survival after sorafenib treatment and with overall survival. Of 79 patients, 63 (79.7 %) received one or more subsequent therapies (44 and 19 patients in groups A and B, respectively). The five patients who survived more than two years after sorafenib treatment was discontinued responded to therapies targeting intrahepatic lesions. The median survival times of groups A, B, and C were 11.9 months, 5.8 months, and 3.6 months, respectively. Multivariate analysis revealed that group A, Child-Pugh score, serum α-fetoprotein level, and cause of failure of sorafenib treatment were independent prognostic factors for survival after sorafenib treatment. Individual survival after sorafenib treatment correlated highly with overall survival. Targeting intrahepatic lesions may be useful for treating patients with advanced hepatocellular carcinoma patients after sorafenib treatment is discontinued.

In the United States, HCC is the ninth leading cause of cancer deaths. Despite advances in prevention techniques, screening, and new technologies in both diagnosis and treatment, incidence and mortality continue to rise. Cirrhosis remains the most important risk factor for the development of HCC regardless of etiology. Hepatitis B and C are independent risk factors for the development of cirrhosis. Alcohol consumption remains an important additional risk factor in the United States as alcohol abuse is five times higher than hepatitis C. Diagnosis is confirmed without pathologic confirmation. Screening includes both radiologic tests, such as ultrasound, computerized tomography, and magnetic resonance imaging, and serological markers such as α-fetoprotein at 6-month intervals. Multiple treatment modalities exist; however, only orthotopic liver transplantation (OLT or surgical resection is curative. OLT is available for patients who meet or are downstaged into the Milan or University of San Francisco criteria. Additional treatment modalities include transarterial chemoembolization, radiofrequency ablation, microwave ablation, percutaneous ethanol injection, cryoablation, radiation therapy, systemic chemotherapy, and molecularly targeted therapies. Selection of a treatment modality is based on tumor size, location, extrahepatic spread, and underlying liver function. HCC is an

    We performed dynamic CT in 30 cases of hepatocellular carcinoma, and concluded as below. Detecting the stain in the early phase of the dynamic series, it is possible to make a diagnosis of hepatocellular carcinoma. The dynamic CT is effective in a case of small hepatocellular carcinoma in which it is difficult to gain an accurate diagnosis in the routine CT study. The dynamic CT is also effective in the differential diagnosis of hepatic lesions, as other hepatic lesions such as hemangioma and metastatic liver cancer show different patterns compared with hepatocellular carcinoma.

    This is a retrospective analysis of a new treatment modality, intra-arterial administration of Yttrium-90 TheraSphere, for unresectable hepatocellular carcinoma (HCC). Patients with HCC not amenable to surgical treatment who had satisfactory physiological function without comorbid disease or significant pulmonary shunting were eligible for treatment. Patients were categorized into complete, partial, or no response based on serum alpha-fetoprotein (AFP) levels and CT or MRI imaging. Fourteen patients were considered candidates for treatment. Three patients were excluded due to significant hepatopulmonary shunting. Eleven patients were treated with TheraSphere. One patient (9%) had a complete response, eight patients (78%) had a partial response, and two patients (18%) showed no response. Partial and complete responders with AFP-associated HCC demonstrated a median decrease in AFP levels of 79 per cent at 73 days. No patients developed liver toxicity nor died due to treatment. Five patients (45%) died of progressive disease at a median of 7 months post-treatment. Six patients (54%) were alive at a median of 11 months (range, 9 to 20 months). Okuda stage 2 and 3 patients showed a median survival of 11 months and 7 months, respectively. Yttrium-90 TheraSphere treatment for unresectable hepatocellular carcinoma is well tolerated and appears to extend survival.

    Electrochemotherapy provides non-thermal ablation of cutaneous as well as deep seated tumors. Based on positive results of the treatment of colorectal liver metastases, we conducted a prospective pilot study on hepatocellular carcinomas with the aim of testing the feasibility, safety and effectiveness of electrochemotherapy. Electrochemotherapy with bleomycin was performed on 17 hepatocellular carcinomas in 10 patients using a previously established protocol. The procedure was performed during open surgery and the patients were followed for median 20.5 months. Electrochemotherapy was feasible for all 17 lesions, and no treatment-related adverse events or major post-operative complications were observed. The median size of the treated lesions was 24 mm (range 8-41 mm), located either centrally, i.e., near the major hepatic vessels, or peripherally. The complete response rate at 3-6 months was 80% per patient and 88% per treated lesion. Electrochemotherapy of hepatocellular carcinoma proved to be a feasible and safe treatment in all 10 patients included in this study. To evaluate the effectiveness of this method, longer observation period is needed; however the results at medium observation time of 20.5 months after treatment are encouraging, in 15 out of 17 lesions complete response was obtained. Electrochemotherapy is predominantly applicable in patients with impaired liver function due to liver cirrhosis and/or with lesions where a high-risk operation is needed to achieve curative intent, given the intra/perioperative risk for high morbidity and mortality.

    No standard second-line treatments are available for hepatocellular carcinoma patients who fail sorafenib therapy. We assessed the safety and efficacy of metronomic capecitabine after first-line sorafenib failure. Retrospective analysis of consecutive hepatocellular carcinoma patients receiving metronomic capecitabine between January 2012 and November 2014. The primary end-point was safety, secondary end-point was efficacy, including time-to-progression and overall survival. Twenty-six patients (80% Child-Pugh A, 80% Barcelona Clinic Liver Cancer stage C) received metronomic capecitabine (500 mg/bid). Median treatment duration was 3.2 months (range 0.6-31). Fourteen (53%) patients experienced at least one adverse event. The most frequent drug-related adverse events were bilirubin elevation (23%), fatigue (15%), anaemia (11%), lymphoedema (11%), and hand-foot syndrome (7.6%). Treatment was interrupted in 19 (73%) for disease progression, in 4 (15%) for liver deterioration, and in 1 (3.8%) for adverse event. Disease control was achieved in 6 (23%) patients. Median time-to-progression was 4 months (95% confidence interval 3.2-4.7). Median overall survival was 8 months (95% confidence interval 3.7-12.3). Metronomic capecitabine was well tolerated in hepatocellular carcinoma patients who had been treated with sorafenib. Preliminary data show potential anti-tumour activity with long-lasting disease control in a subgroup of patients that warrants further evaluation in a phase III study.

    Prognostic factors in the treatment of local advanced hepatocellular carcinoma with radiotherapy, transcatheter arterial embolization and arterial infusion. The treatment effects of radiotherapy and combination modality therapy for the local advanced hepatocellular carcinoma (HCC) were retrospectively reviewed. Three hundred and fifty-six patients of HCC (187 recurrent cases after surgical resection) were treated by: radiotherapy only ; bi-therapeutic method: hepatic artery ligation (HAL) and/or hepatic artery embolization (HAE) plus radiotherapy; and tri-therapeutic method (bi-therapeutic method plus hepatic artery infusion) from 1975 to 1996. Kaplan-Meier method has been used to evaluate the survival rates. There were no significant differences among these three treatment groups in the symptom relied rate, but the mean relief time period was much shorter in radiotherapy alone group (2.5 vs 44 months, P 0.05). There were evident differences in five-year survivals among these three treatment groups: 0 % for radiotherapy alone, 22.8 % for bi-therapeutic method and 38.8 % for tri-therapeutic method (P < 0.01). The prognosis was influenced by Okuda classification. Non-resectable local advanced HCC can be treated by the combination modality therapy, including radiotherapy, with a quite high cure rate. Radiotherapy alone can relief the symptoms. (authors)

    In order to claim a benefit of screen-based diagnosis for asymptomatic individuals, treatment of occult disease needs to offer survival advantages compared to the treatment of symptomatic disease, yet information on this issue is scarce with regard to hepatocellular carcinoma (HCC) screening. A total of 3353 treatment-naïve, consecutive, newly diagnosed HCC patients [age: 57.9 ± 10.3, male: 2,689 (80.2%), hepatitis B virus: 2555 (76.2%)], diagnosed between 2010 and 2013 were analyzed. Data on the mode of detection was prospectively collected at the time of HCC diagnosis and was used to group patients into occult or symptomatic cases. Overall, 643 (19.2%) patients were symptomatic cases. The proportion of patients undergoing resection, radiofrequency ablation or transplantation were lower in symptomatic cases than occult cases (20.8 vs. 56.2%, p offered a survival benefit to patients over symptomatic cases. These data support screening practices for asymptomatic individuals to diagnose occult HCC.

    Fibrolamellar hepatocellular carcinoma (FL-HCC) is a malignant liver tumor which is thought to be a variant of conventional hepatocellular carcinoma (HCC). It accounts for a small proportion of HCC cases and occurs in a distinctly different group of patients which are young and usually not in the setting of chronic liver disease. The diagnosis of FL-HCC requires the integration of clinical information, imaging studies, and histology. In terms of the treatment options, the only potentially curative treatment option for patients who have resectable disease is surgery either liver resection (LR) or liver transplantation (LT). When performed in a context of aggressive therapy, long-term outcomes after surgery, particularly liver resection for FL-HCC, were favorable. The clinical outcome of patients with unresectable disease is suboptimal with median survival of less than 12 months. The aim of this review is to update the available evidence on diagnosis, treatment options, outcome predictors, and recent developments of patients with this rare disease and to provide a summarized overview of the available literature.

    CT was investigated in 125 cases of hepatocelluar carcinoma and 47 cases of metastatic hepatic neoplasm. The entire contour of each tumor was traced and the average CT value in the tumor was estimated. As a result, the CT value for hepatocellular carcinoma tended to be higher on plain CT and also after contrast enhancement. The CT findings seen frequently were as follows: capsule in 76 cases (60.8%) and septum in 67 cases (53.6%); tumor thrombus in portal vein in 39 cases (31.2%) and that in inferior vena cava in 3 cases (2.4%); localized enlargement of hepatic bile duct in 24 cases (19.2%). These findings were rarely seen in the cases of metastatic hepatic neoplasm. As a relatively outstanding feature of hepatic metastases, a double contour, like concentric circles or contour lines, with a relatively large inner circle or contour line, was found in 21 cases (44.7%). By paying attention to the change of CT value on contrast enhancement and the characteristic image of each case, hepatocellular carcinoma could be differentiated from metastatic hepatic neoplasm with high probability.

    In this review paper, available data on radioembolization of unresectable hepatocellular carcinoma (HCC) using commercially available radiopharmaceuticals, respectively (131)I-Lipiodol, Therasphere (glass-microspheres) and SIRspheres (resin-microspheres) are reviewed. In the palliative setting, (131)I-Lipiodol was shown to yield response rates of 17-92% which in patients with portal vein thrombosis (PVT) translate into a survival benefit as evidenced by a phase III randomized trial. Furthermore, in terms of efficacy, (131)I-Lipiodol is as efficacious as trans-arterial chemoembolization (TACE) but far better tolerated. In the adjuvant setting, improved recurrence-free and overall survival when compared to surgery alone have been reported but these results warrant confirmation by randomized prospective trials. Similar to (131)I-Lipiodol, when administered in a palliative setting, radioembolization using (90)Y microspheres was proven effective for selected cases of non-resectable HCC and well tolerated. Available data suggest that Therasphere treatment outperforms TACE both in terms of response as in terms of event-free survival in unresectable HCC. However, this finding needs confirmation by randomized prospective trials. Therasphere treatment was also shown to limit progression of HCC allowing potential candidates for orthotopic liver transplantation (OLT) more time to wait for donor organs as well as to downstage the HCC disease to such an extent that patients that were initially not, as yet become eligible for OLT with a gain in survival. Finally, Therasphere was shown to be safe and efficacious in HCC patients presenting with PVT, reason for which approval was granted for this indication by the FDA.

    Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and leading cause of death among patients with cirrhosis. Treatment guidelines are based according to the Barcelona Clinic Liver Cancer staging system. The choice among therapeutic options that include liver resection, liver transplantation, locoregional, and systemic treatments must be individualized for each patient. The aim of this paper is to review the outcomes that can be achieved in the treatment of HCC with the heterogeneous therapeutic options currently available in clinical practice. PMID:25132740

    With the advent of gray scale ultrasonographic equipment, the parenchymal disease of liver is more easily evaluated. Ultrasonography is a non-invasive technique, different from angiography, and performed without discomfort to patient. And also ultrasonography can be used in assessing the liver in cases showing equivocal scintigraphy and in differentiation of solid and cystic masses, first detected on scintigrams. Therefore, the complementary use of ultrasonography, Tc-99m-sulfur colloid scan and angiography provides better diagnostic accuracy for the detection of hepatocellular carcinoma, and moreover, sequential ultrasonographic studies in the same patient are valuable of following the course of hepatocellular carcinoma and monitoring the effectiveness of therapy for hepatocellular carcinoma. In thirty patients with histologically proven hepatocellular carcinoma, an analysis of ultrasound manifestation is made and the results are as follows; 1. Ultrasound manifestation of hepatocellular carcinoma by gray scale showed four different sonographic patterns including discrete echo free, discrete echogenic, ill defined echogenic and mixed patterns. 2. The size of hepatocellular carcinoma by ultrasonographic measurement was larger than 5 cm in diameter in 28 cases. 3. In 7 cases performed with angiography, all echogenicities of hepatocellualr carcinoma were correlated with the findings of vascularity of angiography. 4. In cases combined with liver cirrhosis, the sonographic pattern of hepatocellular carcinoma appeared to be discrete or ill defined echogenic patterns.

    A 61 year old asymptomatic woman visited our outpatient clinic (OPC with a high alpha-fetal protein (AFP level. A computed tomogram (CT revealed a 4.1 cm hypervascular tumor (arterial phase at S4 of the liver and washed out in venous phase. Her Hepatitis B Surface Antigen (HBsAg was negative and Hepatitis C Antibody (anti-HCV was positive. This patient also had esophageal varices. She refused any treatment and returned to our OPC about 2 years later. Her AFP level was 11.8 ng/ml. The following CT scan revealed a small amount of cirrhosis, but no mass, in the liver, so that spontaneous remission of HCC was determined. She was treated by oral diuretics. Here we report the case and review of literature.

    Full Text Available Hepatocellular carcinoma (HCC has an insidious onset and when a confirmed diagnosis is made, most patients lose the chance for surgery and are given transarterial chemoembolization (TACE as palliative treatment. However, repeated TACE may lead to overexpression of hypoxia-inducible factor 1α (HIF-1α and vascular endothelial growth factor (VEGF, liver injury, and reduced immune function and has poor long-term efficacy. The introduction of Huai′er granules may help to change the current status. Studies in China and foreign countries have shown that Huai′er granules exert a remarkable anti-tumor effect by blocking cell cycle, inducing cell apoptosis, inhibiting cell proliferation and invasion, and blocking the hepatitis B-hepatocellular carcinoma pathway. Meanwhile, as an adjuvant drug for HCC, Huai′er granules cover the shortcomings of TACE from multiple aspects and can effectively inhibit the overexpression of HIF-1α and VEGF, improve liver injury and immunity, enhance the effect of chemotherapy drugs, and reverse drug resistance. Many clinical studies have confirmed the remarkable advantages of Huai′er granules combined with TACE, and their synergistic effect helps to enhance anti-tumor effect and improve short- and long-term survival rates.

    Hepatocellular carcinoma (HCC) is currently the sixth most common type of cancer with a high mortality rate and an increasing incidence worldwide. Its etiology is usually linked to environmental, dietary or life-style factors. HCC most commonly arises in a cirrhotic liver but interestingly an increasing proportion of HCCs develop in the non-fibrotic or minimal fibrotic liver and a shift in the underlying etiology can be observed. Although this process is yet to be completely understood, this changing scenario also has impact on the material seen by pathologists, presenting them with new diagnostic dilemmas. Histopathologic criteria for diagnosing classical, progressed HCC are well established and known, but with an increase in detection of small and early HCCs due to routine screening programs, the diagnosis of these small lesions in core needle biopsies poses a difficult challenge. These lesions can be far more difficult to distinguish from one another than progressed HCC, which is usually a clear cut hematoxylin and eosin diagnosis. Furthermore lesions thought to derive from progenitor cells have recently been reclassified in the WHO. This review summarizes recent developments and tries to put new HCC biomarkers in context with the WHOs reclassification. Furthermore it also addresses the group of tumors known as combined hepatocellular-cholangiocellular carcinomas.

    Radiofrequency ablation (RFA) is a well-established treatment modality in the treatment of early hepatocellular carcinoma (HCC) [1]. Safe trajectory of the RFA probe is crucial in decreasing collateral tissue damage and unwarranted probe transgression. As a percutaneous technique, however, the trajectory of the needle is sometimes constrained by the available imaging plane. The presence of a hemangioma beside an HCC is uncommon but poses the question of safety related to probe transgression. We hereby describe a case of transhemangioma ablation of a dome HCC.

In a majority of the cases, HCC is associated with the underlying chronic liver disease, and it is diagnosed in advanced stage of disease when curative treatment options are not applicable. Sorafenib is a treatment of choice for patients with performance status 1 or 2 and/or macrovascular invasion or extrahepatic spread, and regorafenib is the only systemic treatment found to provide survival benefit in HCC patients progressing on sorafenib treatment. Other drugs tested in different trials failed to demonstrate any benefit. Disappointing results of numerous trials testing the efficacy of various drugs indicate that HCC has low sensitivity to chemotherapy that is in great part caused by multidrug resistance. Immunotherapy for HCC is a new challenging treatment option and involves immune checkpoint inhibitors/antibody-based therapy and peptide-based vaccines. Another challenging approach is microRNA-based therapy that involves two strategies. The first aims to inhibit oncogenic miRNAs by using miRNA antagonists and the second strategy is miRNA replacement, which involves the reintroduction of a tumor-suppressor miRNA mimetic to restore a loss of function.

    With the rising incidence of chronic liver disease caused by viral hepatitis, hepatocellular carcinoma is showing a corresponding rise worldwide. Surgery remains the mainstay of treatment, but patients unfit for surgery or liver transplantation form the bulk of those presenting with this disease. Palliative treatments are being used to treat those and radiological modalities form the mainstay of the treatment. Radiology plays a major role in the diagnosis, treatment and follow-up of hepatocellular carcinoma. Current radiological treatment modalities include percutaneous ethanol ablation, radiofrequency ablation and trans-arterial chemoembolization. This update highlights the recent advancements in the field and compares their relative merits and demerits. (author)

    Mortality rate of hepatocellular carcinoma is high. The majority of the patients are diagnosed in advanced stage and lose surgical opportunities. Many studies have reported transcatheter arterial chemoembolization (TACE) is an effective treatment for unresectable hepatocellular carcinoma, and recommended TACE as a standard treatment for hepatocellular carcinoma of Barcelona Clinical Liver Cancer staging (BCLC staging) B. However, TACE can hardly fully embolize tumor blood supply, TACE postoperative hemodynamics and angiogenesis can induce tumor recurrence and metastasis.

    Purpose: To describe efficacy and safety of stereotactic body radiation therapy (SBRT) for the treatment of inoperable hepatocellular carcinoma. Methods: The records of 77 consecutive patients treated with SBRT for 97 liver-confined HCC were reviewed. A total dose of 45 Gy in 3 fractions was prescribed to the 80% isodose line. Local control (LC), overall survival (OS), progression-free survival (PFS) and toxicity were studied. Results: The median follow-up was 12 months. The median tumor diameter was 2.4 cm. The LC rate was 99% at 1 and 2 years. The 1 and 2-year OS were 81.8% and 56.6% respectively. The median time to progression was 9 months (0–38). The rate of hepatic toxicity was 7.7% [1.6–13.7], 14.9% [5.7–23.2] and 23.1% [9.9–34.3] at 6 months, 1 year and 2 years respectively. In multivariate analysis, female gender (HR 7.87 [3.14–19.69]), a BCLC B-C stage (HR 3.71 [1.41–9.76]), a sum of all lesion diameters ⩾2 cm (HR 7.48 [2.09–26.83]) and a previous treatment (HR 0.10 [0.01–0.79]) were independent prognostic factors of overall survival. Conclusion: SBRT allows high local control for inoperable hepatocellular carcinomas. It should be considered when an ablative treatment is indicated in Child A patients

    Hepatocellular carcinoma (HCC) is a common cancer that typically occurs in the setting of cirrhosis and chronic hepatitis virus infections. HCC is considered currently as global problem; its incidence is expected to increase dramatically by the next few decades. More than 90 % of the accidentally diagnosed patients have non resectable tumor. Portal vein thrombosis, diffuse multifocal liver infiltration and large tumor burden are considered to be a great obstacle in front of the modern lines of treatment, even with Child A liver cirrhosis. Transarterial intrahepatic application of Yttrium-90 glass microspheres may allow effective local ablative treatment of patients with intrahepatic advanced hepatocellular carcinoma (HCC) with or without portal vein thrombosis. The aim of this open-label phase II study was to validate evidence on the safety and efficacy of this treatment in an European cohort of patients with locally advanced HCC such as (large tumor burden, multifocal distribution, portal vein thrombosis). And to assess the response rate according to different approved response assessment guidelines (WHO, RECIST and EASL). Patients and Methods Starting from November 2006 till March 2009, one hundred and eight advanced unresectable HCC patients with and without portal vein thrombosis were included in this prospective study. Yttrium-90 microspheres radiotherapy was performed in a lobar fashion through the right or left hepatic artery. In bilobar disease, right and left liver lobe were treated with 4-6 weeks intervals in between. Response rate was assessed according to different international response assessment criteria (WHO, RECIST and EASL) with sequential computed tomography scans till the last clinical visit or death. The safety of this technique was assessed according to the Common Toxicity Criteria version 3

    To investigate the efficacy and safety of transarterial chemoembolization (TACE)-based multimodal treatment in patients with large hepatocellular carcinoma (HCC). A total of 146 consecutive patients were included in the analysis, and their medical records and radiological data were reviewed retrospectively. In total, 119 patients received TACE-based multi-modal treatments, and the remaining 27 received conservative management. Overall survival (P<0.001) and objective tumor response (P=0.003) were significantly better in the treatment group than in the conservative group. After subgroup analysis, survival benefits were observed not only in the multi-modal treatment group compared with the TACE-only group (P=0.002) but also in the surgical treatment group compared with the loco-regional treatment-only group (P<0.001). Multivariate analysis identified tumor stage (P<0.001) and tumor type (P=0.009) as two independent pre-treatment factors for survival. After adjusting for significant pre-treatment prognostic factors, objective response (P<0.001), surgical treatment (P=0.009), and multi-modal treatment (P=0.002) were identified as independent post-treatment prognostic factors. TACE-based multi-modal treatments were safe and more beneficial than conservative management. Salvage surgery after successful downstaging resulted in long-term survival in patients with large, unresectable HCC.

    Full Text Available Abstract:MicroRNA (miRNA play important roles in post-transcriptional gene regulation. In recent years, miRNA has become a hot topic in the research on the development and progression of tumors, and gene targeting therapy for malignant tumors has achieved preliminary progress. As one of the first discovered miRNA, let-7 can regulate the cell cycle and angiogenesis and is involved in the proliferation, differentiation, and apoptosis of various tumor cells. Most members of the let-7 family can act as tumor suppressor gene and have low expression in various tumor tissues and high expression in the serum of patients with malignant tumors. Let-7 is closely associated with the invasion and drug resistance of hepatocellular carcinoma (HCC. The studies above show that let-7 might become a new marker for the early diagnosis of HCC and provide new targets for the treatment of HCC.

    A pilot trial is currently under way at our institution to determine the potential of new Y-90 glass microspheres (Theraspheres, Theragenics Corp., Atlanta) for the treatment of primary hepatocellular carcinoma. The Y-90 microspheres are injected through a percutaneous hepatic artery catheter positioned angiographically. The injection is facilitated by a new delivery system. Prior to the injection of the Y-90 microspheres, the presence of shunting is assessed by injecting Tc-99m human albumin microspheres (HAM) via the hepatic artery catheter. Bremsstrahlung scans done after injection demonstrate the distribution the Y-90 microspheres within the liver and the lack of extrahepatic activity. In the first group of patients treated, no significant toxicity was demonstrated for absorbed doses between 5,000 and 10,000 rad to the liver, and up to 20,000 rad to the tumor itself

    2018-01-01

    Full Text Available Introduction: Hepatic transarterial chemoembolization is a widely used technique for the treatment of hepatocellular carcinoma. The most common complication of this procedure is postembolization syndrome. The main objective of this study was to assess risk factors for the development of postembolization syndrome. Material and Methods: Single-centre retrospective analysis of 563 hepatic transarterial chemoembolization procedures from January 1st, 2014 – December 31st, 2015. Hepatic transarterial chemoembolization was performed with ½ - 2 vials of 100 - 300 μm microspheres loaded with doxorubicin. Patients who experienced postembolization syndrome were identified based on prolongation of hospitalization due to pain, fever, nausea and/or vomiting. A control group with the patients who did not have postembolization syndrome was randomly created (three controls for one case. Descriptive analysis and multivariate logistic regression were performed. Results: The overall prevalence of postembolization syndrome was 6.2%. Hepatic transarterial chemoembolization with doxorubicin dosage above 75 mg (more than one vial, the size of the largest nodule and female gender had statistically significant relation with development of postembolization syndrome (p = 0.030, p = 0.046 and p = 0.037, respectively. Discussion: Doxorrubicin dosage above 75 mg is associated with a higher risk of postembolization syndrome. This result can be helpful for decision-making in clinical practice, whenever it is possible to avoid a higher dose without compromising the efficacy of the treatment. The size of the largest nodule and female gender also constitute risk factors for postembolization syndrome. The other variables studied were not related to the development of postembolization syndrome. Conclusion: The dose of doxorrubicin, the size of the largest nodule treated and female gender are potential risk factors for the development of postembolization syndrome after hepatic

The exact roles of triclosan in regulating human hepatocellular carcinoma development and treatment remain unknown. Methods: MHCC97-H, a highly aggressive HCC cell line, was treated with indicated concentration of triclosan or sorafenib. The expression of drug-resistance genes was examined by qPCR. The clearance or metabolism of sorafenib was determined by liquid chromatograph-mass spectrometer/mass spectrometer (LC-MS/MS. MTT assay was used to examine the MHCC97-H cell proliferation. Nude mice were used to exam the anti-tumor effect of sorafenib on subcutaneous and intrahepatic growth of MHCC97-H cells. Results: In the present study, triclosan could induce the expression of drug-resistance genes in MHCC97-H cells (a highly aggressive HCC cell line, accelerate the clearance of sorafenib, and attenuate the anti-proliferation effect of this molecular targeted agent in MHCC97-H cells. Triclosan decreased the antitumor effect of sorafenib on subcutaneous and intrahepatic growth of MHCC97-H in nude mice. Conclusion: By discovering the fact that triclosan treatment enhances sorafenib resistance in HCC cells, this work suggests exposure of triclosan is detrimental to HCC patients during chemotherapy.

    To evaluate the incidence and risk factors of post-treatment intracranial hemorrhage of brain metastases from hepatocellular carcinoma (HCC). Medical records of 81 patients who have been diagnosed of brain metastases from HCC and underwent surgery, radiosurgery and/or whole brain radiotherapy (WBRT) between January 2000 and December 2013 were retrospectively reviewed. Intracranial hemorrhage was present in 64 patients (79%) at the time of diagnosis. Median value of alpha-fetoprotein (AFP) level was 1,700 ng/mL. The Eastern Cooperative Oncology Group (ECOG) performance status for 20 patients was greater than 2. Fifty-seven patients underwent WBRT and the others were treated with surgery and/or radiosurgery without WBRT. During follow-up, 12 events of intracranial hemorrhage after treatment were identified. Three-month post-treatment hemorrhage rate was 16.1%. Multivariate analyses revealed that ECOG performance status, AFP, and WBRT were associated with post-treatment hemorrhage (p = 0.013, 0.013, and 0.003, respectively). Kaplan-Meier analysis showed that 3-month post-treatment hemorrhage rate of new lesion was higher in patients treated without WBRT, although statistical significance was not reached. (18.6% vs. 4.6%; p = 0.104). Ten of 12 patients with post-treatment hemorrhage died with neurologic cause. WBRT should be considered to prevent post-treatment hemorrhage in the treatment of brain metastases from HCC.

    A variety of unfulfilled needs may trigger doctor-shopping behavior (DSB) in patients. In oncology, treatment results usually cause patients the most concern. This study investigated the association of DSB with active treatments received by patients with hepatocellular carcinoma (HCC) and outcomes. With approval from the institutional review board, all patients registered in the cancer database of a teaching hospital and diagnosed as having HCC by self-referral from outside hospitals or by in-house diagnosis were retrospectively identified. Patient data were then reviewed and analyzed via electronic medical records. Hepatitis B carriers were significantly more likely than noncarriers to show first-time DSB. Recurrent disease was less likely to result in DSB than predicted. Patients from outside hospitals not receiving upfront first treatment after diagnosis were significantly more likely to show more frequent DSB than those receiving it. Male patients eligible for salvage treatment were less likely to have frequent occurrences of DSB than their female counterparts. Receiving first salvage treatment was not associated with more frequent DSB. Treatment recommendations offered in the study hospital did not influence patients' decisions to leave or stay. Only elderly patients (>70 years) were less likely to show DSB. DSB can occur throughout the entire course of treatment for HCC for a variety of reasons. Active treatments, disease status, and patient characteristics all exerted an influence on DSB.

    Hepatocellular carcinoma (HCC) is a severe complication of advanced liver disease with a worldwide incidence of more than 600,000 patients per year. Liver function, clinical performance status, and tumor size are considered in the Barcelona Clinic Liver Cancer (BCLC) system. While curative treatment options are available for early stages, most patients present with intermediate- or advanced-stage HCC, burdened with a poor prognosis, substantially influenced by the degree of liver-function impairment. Hypervascularization is a major characteristic of HCC, and antiangiogenic treatments are the basis of treatment in noncurative stages, including interventional and pharmacological treatments. Currently, the tyrosine-kinase inhibitor sorafenib is still the only approved drug for HCC. Further improvements in survival in patients with intermediate- and advanced-stage HCC may be anticipated by both multimodal approaches, such as combination of interventional and systemic treatments, and new systemic treatment options. Until now, the Phase III development of other tyrosine-kinase inhibitors in patients with advanced HCC has failed due to minor efficacy and/or increased toxicity compared to sorafenib. However, promising Phase II data have been reported with MET inhibitors in this hard-to-treat population. This review gives a critical overview of antiangiogenic drugs and strategies in intermediate- and advanced-stage HCC, with a special focus on safety. PMID:24204170

    Full Text Available ObjectiveTo compare clinical efficacy and recurrence between surgical resection and radiofrequency ablation (RFA in the treatment of small hepatocellular carcinoma (HCC. MethodsThe clinical data of 97 patients with small HCC, who underwent surgical resection or RFA as the initial treatment in The First Hospital of Jilin University from January 2002 to December 2008, were collected. Sixty-three cases, who survived 2 years after treatment, were followed up; of the 63 cases, 34 underwent surgical resection, and 29 underwent RFA. The recurrence of these patients was analyzed retrospectively. The measurement data were analyzed by chi-square test. The Cox regression analysis was used for determining the risk factors for recurrence. The log-rank test was used for disease-free survival (DFS difference analysis. ResultsThe 3-month, 1-year, and 2-year intrahepatic recurrence rates for the patients who underwent surgical resection were 15%, 38%, and 64%, respectively, versus 21%, 35%, and 45% for those who underwent RFA, without significant differences between the two groups of patients. The intrahepatic recurrence after initial treatment was not significantly associated with treatment method, sex, age, Child-Pugh grade, tumor size, number of nodules, presence of cirrhosis, and alpha-fetoprotein level. There was no significant difference in DFS between the two groups of patients. ConclusionRFA produces a comparable outcome to that by surgical resection in the treatment of small HCC. RFA holds promise as a substitute for surgical resection.

    Although liver resection is considered the most effective treatment for hepatocellular carcinoma (HCC), treatment outcomes are unsatisfactory because of the high rate of HCC recurrence. Since we reported hepatitis B e-antigen positivity and high serum hepatitis B virus (HBV) DNA concentrations are strong risk factors for HCC recurrence after curative resection of HBV-related HCC in the early 2000s, many investigators have demonstrated the effects of viral status on HCC recurrence and post-treatment outcomes. These findings suggest controlling viral status is important to prevent HCC recurrence and improve survival after curative treatment for HBV-related HCC. Antiviral therapy after curative treatment aims to improve prognosis by preventing HCC recurrence and maintaining liver function. Therapy with interferon and nucleos(t)ide analogs may be useful for preventing HCC recurrence and improving overall survival in patients who have undergone curative resection for HBV-related HCC. In addition, reactivation of viral replication can occur after liver resection for HBV-related HCC. Antiviral therapy can be recommended for patients to prevent HBV reactivation. Nevertheless, further studies are required to establish treatment guidelines for patients with HBV-related HCC. PMID:26217076

    Full Text Available Abstract Background Hepatocellular carcinoma is a primary malignant tumor of the liver that accounts for an important health problem worldwide. Only 10 to 15% of hepatocellular carcinoma patients are suitable candidates for treatment with curative intent, such as hepatic resection and liver transplantation. A majority of patients have locally advanced, liver restricted disease (Barcelona Clinic Liver Cancer (BCLC staging system intermediate stage. Transarterial loco regional treatment modalities offer palliative treatment options for these patients; transarterial chemoembolization (TACE is the current standard treatment. During TACE, a catheter is advanced into the branches of the hepatic artery supplying the tumor, and a combination of embolic material and chemotherapeutics is delivered through the catheter directly into the tumor. Yttrium-90 radioembolization (90Y-RE involves the transarterial administration of minimally embolic microspheres loaded with Yttrium-90, a β-emitting isotope, delivering selective internal radiation to the tumor. 90Y-RE is increasingly used in clinical practice for treatment of intermediate stage hepatocellular carcinoma, but its efficacy has never been prospectively compared to that of the standard treatment (TACE. In this study, we describe the protocol of a multicenter randomized controlled trial aimed at comparing the effectiveness of TACE and 90Y-RE for treatment of patients with unresectable (BCLC intermediate stage hepatocellular carcinoma. Methods/design In this pragmatic randomized controlled trial, 140 patients with unresectable (BCLC intermediate stage hepatocellular carcinoma, with Eastern Cooperative Oncology Group performance status 0 to 1 and Child-Pugh A to B will be randomly assigned to either 90Y-RE or TACE with drug eluting beads. Patients assigned to 90Y-RE will first receive a diagnostic angiography, followed by the actual transarterial treatment, which can be divided into two sessions in case

    Since the discovery of the hepatitis B virus (HBV) by Blumberg et al. in 1965, its genome, sequence, epidemiology, and hepatocarcinogenesis have been elucidated. Globally, hepatitis B virus (HBV) is still responsible for the majority of hepatocellular carcinoma (HCC). HCC is the sixth-most common cancer in the world and the second-most common cancer death. The ultimate goal of treating HBV infection is the prevention of HCC. Fortunately, anti-HBV treatment with nucleos(t)ide analogues (NAs), which began with lamivudine in 1998, has resulted in remarkable improvements in the survival of patients with chronic hepatitis B and a reduced incidence of HCC. These results were documented with lamivudine, entecavir, and tenofovir. Nonetheless, as the duration of antiviral treatment increases, the risk for HCC still remains despite undetectable HBV DNA in serum, as reported by different investigators with observation up to 4⁻5 years. In our own experience, we are witnessing the development of HCC in patients who have received antiviral treatment. Some have enjoyed negative serum HBV DNA for over 12 years before developing HCC. Current treatment with NAs can effectively suppress the replication of the virus but cannot eradicate the covalently closed circular DNA (cccDNA) that is within the nucleus of hepatocytes. There still remains a great need for a cure for HBV. Fortunately, several compounds have been identified that have the potential to eradicate HBV, and there are ongoing clinical trials in progress in their early stages.

    This study aimed to evaluate the antitumor activity of platinum nanoparticles compared with cis-platin both in vitro and in vivo in the treatment of hepatocellular carcinoma induced in rats. The treatment efficacy of platinum nanoparticles was evaluated by measuring antioxidant activities against oxidative stress caused by diethylnitrosamine in liver tissue. The measurements included reduced glutathione content and superoxide dismutase activity, as well as malondialdehyde level. Liver function tests were also determined, in addition to the evaluation of serum alpha-fetoprotein, caspase-3, and cytochrome c in liver tissue. Total RNA extraction from liver tissue samples was also done for the relative quantification of B-cell lymphoma 2, matrix metallopeptidase 9, and tumor protein p53 genes. Histopathological examination was also performed for liver tissue. Results showed that platinum nanoparticles are more potent than cis-platin in treatment of hepatocellular carcinoma induced by diethylnitrosamine in rats as it ameliorated the investigated parameters toward normal control animals. These findings were well appreciated with histopathological studies of diethylnitrosamine group treated with platinum nanoparticles, suggesting that platinum nanoparticles can serve as a good therapeutic agent for the treatment of hepatocellular carcinoma which should attract further studies.

    The prognosis of spontaneous rupture of hepatocellular carcinoma (HCC) remains unclear. We investigated the prognosis of patients with ruptured HCC based on the treatments and prognostic factors associated with long-term survival. The prognoses of 64 consecutive patients treated for ruptured HCC from 1986 to 2013 were analyzed according to their methods of treatment. The prognostic factors of 16 surgical patients were identified, and their overall survival (OS) and recurrence rates were compared to 1,157 surgical patients who underwent surgery for non-ruptured HCC. The surgical outcomes were also compared using a propensity score matching method. Surgery was associated with a better OS. Curative resection was the only independent prognostic factor in surgical patients with ruptured HCC (p = 0.040). Although the OS of surgical patients with non-ruptured HCC was found to be significantly better than that of the patients with ruptured HCC, no significant difference in OS was observed after propensity score matching. A curative resection should be the objective of treatment, assuming the suitability of the patient's clinical condition. When the liver function reserve and tumor extension of patients with ruptured and non-ruptured HCC are similar, then their surgical outcomes may not be significantly different. © 2015 S.

    To present a critical review of yttrium-90 (TheraSphere) for the treatment of hepatocellular carcinoma (HCC). Medical literature databases (Medline, Cochrane Library, and CANCERLIT) were searched for available literature concerning the treatment of HCC with TheraSphere. These publications were reviewed for scientific and clinical validity. Studies pertaining to the use of yttrium-90 for HCC date back to the 1960s. The results from the early animal safety studies established a radiation exposure range of 50-100 Gy to be used in human studies. Phase I dose escalation studies followed, which were instrumental in delineating radiation dosimetry and safety parameters in humans. These early studies emphasized the importance of differential arteriolar density between hypervascular HCC and surrounding liver parenchyma. Current trends in research have focused on advancing techniques to safely implement this technology as an alternative to traditional methods of treating unresectable HCC, such as external beam radiotherapy, conformal beam radiotherapy, ethanol ablation, trans-arterial chemoembolization, and radiofrequency ablation. Yttrium-90 (TheraSphere) is an outpatient treatment option for HCC. Current and future research should focus on implementing multicenter phase II and III trials comparing TheraSphere with other therapies for HCC

    Percutaneous radiofrequency ablation (RFA) is well established in the treatment of hepatocellular carcinoma (HCC). Due to its curative potential, it is the method of choice for non resectable BCLC (Barcelona Liver Clinic) 0 and A. RFA challenges surgical resection for small HCC and is the method of choice in bridging for transplantation and recurrence after resection or transplantation. The technical feasibility of RFA depends on the size and location of the HCC and the availability of ablation techniques (one needle techniques, multi-needle techniques). More recently, stereotactic multi-needle techniques with 3D trajectory planning and guided needle placement substantially improve the spectrum of treatable lesions including large volume tumors. Treatment success depends on the realization of ablations with large intentional margins of tumor free tissue (A0 ablation in analogy to R0 resection), which has to be documented by fusion of post- with pre-ablation images, and confirmed during follow-up imaging.

    Highlights: •Although a patient with a ruptured HCC is generally considered to have a poor prognosis and treated as T4 in the 7th edition of the AJCC/UICC, some ruptured cases show a good clinical course. •There are no clear criteria established for treating a ruptured hepatocellular carcinoma (HCC) which is classified as T4 in TNM stage of UICC 7th. •This article describes that better prognosis can be expected with curative treatment in patients with a ruptured HCC, especially those with a single tumor, and without decompensated liver cirrhosis and PVTT/extrahepatic metastasis. T4 classification should not include all types of ruptured HCC. -- Abstract: Background: There are no clear criteria established for treating a ruptured hepatocellular carcinoma (HCC). To elucidate the clinical features of affected patients, we examined prognosis and therapy choices. Materials/methods: We enrolled 67 patients treated for a ruptured HCC (HCV 44, HBV 5, HBV + HCV 1, alcohol 2, others 15; naïve HCC 34, recurrent 33) from 2000 to 2013, and investigated their clinical background and prognosis. Results: Median survival time (MST) for all cases was 4 months. For patients who survived for more than 1 year after rupture, the percentages of Child-Pugh C and positive for portal vein tumor thrombosis (PVTT)/extrahepatic metastasis were less than for those who died within 1 year. Child-Pugh classification (A:B:C = 14:15:5 vs. 4:9:20, P < 0.001) was better, while the percentage of patients with multiple tumors was lower [19/34 (55.9%) vs. 29/33 (87.9%), respectively; P < 0.001] in the naïve group. The 1- and 3-year survival rates were better in the naïve as compared to the recurrent group (60.6% and 33.3% vs. 12.6% and 0%, respectively; P < 0.01). MST according to modified TNM stage (UICC 7th) calculated after exclusion of T4 factor of rupture, stage I was better than others (22.7 vs. (II) 2.2, (III) 1.2, and (IV) 0.7 months) (P = 0.010).

    Purpose: To evaluate the therapeutic efficacy and safety of supplemental transcatheter arterialchemoembolization (TACE) through the extrahepatic collateral omentalartery (OA) for the treatment of hepatocellular carcinoma (HCC). Methods: We studied 21 patients with extrahepatic collaterals of the OA, among 1,512 patients with HCC who had undergone angiography. HCCs supplied by collateral OAs were located at: segment IV in seven, segment V in five, segment III in three, segment VI in three and segment VIII in three patients (Couinaud classification of segments). On preoperative CT scans, every HCC was abutting the liver surface. Adjacent omental infiltration or engorgement was noted in 11 patients. Celiac and hepatic arteriograms showed hypertrophy of the feeding OA in all patients. TACE of the OA was performed in 19 patients with an emulsion of iodized oil and doxorubicin hydrochloride.Embolization with gelatin sponge particles was added in five patients. Results: Collaterals of the OA to the HCC were found on the first to seventeenth sessions of TACE. On follow-up CT scans, five patients showed complete uptake of iodized oil in the tumor. Partial uptake of iodized oil was noted in 13 patients and no uptake in one patient. There was no serious complication that related to the omental embolization, such as omental or bowel ischemia. The cumulative survival rates from the time of the TACE of the OA were 81% at 6 months and 68% at 12 months. Conclusion: TACE of the OA is safe and has a potential therapeutic effect in the treatment of HCC

    Hepatocellular carcinoma (HCC) is the sixth most common cancer in the world. The majority of patients with HCC present with unresectable disease. These patients have historically had limited treatment options secondary to HCC demonstrating chemoresistance to the currently available systemic therapies. Additionally, normal liver parenchyma has shown intolerance to tumoricidal radiation doses, limiting the use of external beam radiation. Because of these limitations, novel percutaneous liver-directed therapies have emerged. The targeted infusion of radioactive microspheres (radioembolization) represents one such therapy. Radioembolization is a minimally invasive transcatheter therapy through which radioactive microspheres are infused into the hepatic arteries that supply tumor. Once infused, these microspheres traverse the hepatic vascular plexus and selectively implant within the tumor arterioles. Embedded within the arterioles, the 90Y impregnated microspheres emit high energy and low penetrating radiation doses selectively to the tumor. Radioembolization has recently shown promise for the treatment of patients with unresectable HCC. The objective of this review article is to highlight twocurrently available radioembolic devices (90Y, 188Rh) and provide the reader with a recent review of the literature.

    To evaluate the long-term follow-up results of percutaneous ethanol injection (PEI) for the treatment of hepatocellular carcinoma (HCC) in Korea. Sixty-eight nodular HCCs initially detected in 64 patients, were subjected to US-guided PEI as a first-line treatment. Long-term survival rates, local tumor progression rates, and complications were evaluated, as were the influences of tumor size and Child-Pugh class on these variables. No major complications occurred. The overall survival rates of the 64 patients at three and five years were 71% and 39%, and their cancer-free survival rates were 22% and 15%, respectively. The overall survival rate of patients with a small HCC (≤ 2 cm) was significantly higher (p = 0.014) than that of patients with a medium-sized HCC (≤ 2 cm). The overall survival rate of patients with Child- Pugh class A was significantly higher (p = 0.049) than that of patients with Child- Pugh class B. Of 59 cases with no residual tumor, local tumor progression was observed in ablation zones in 18, and this was not found to be significantly influenced by tumor size or Child-Pugh class. The results of our investigation of the long-term survival rates of PEI in HCC patients in Korea (a hepatitis B virus-endemic area) were consistent with those reported previously in hepatitis C endemic areas. Patients with a smaller tumor or a better liver function exhibited superior survival rates

    To present the findings of a risk-stratification survival analysis with use of data collected on a heterogeneous group of patients with hepatocellular carcinoma (HCC) treated with TheraSphere. Baseline, treatment, and follow-up data were collected and analyzed from 121 TheraSphere-treated patients. Survival analyses were performed to identify those variables most strongly associated with 3-month mortality. The presence of any of the identified risk variables resulted in the assignment of a patient to the high-risk category. Five liver reserve and two non-liver reserve variables were identified and used to stratify patients into low- or high-risk groups. Sixteen of the 33 patients assigned to the high-risk group (49%) did not survive the first 3 months after treatment, compared with six of the 88 patients assigned to the low-risk group (7%; Fisher exact test, P TheraSpheres should be evaluated for the presence of the risk variables described herein. The absence of these variables is predictive of improved survival (median of 466 days) compared with patients at high risk (median of 108 days).

    Hepatocellular carcinoma (HCC) is one of the major malignant diseases in many healthcare systems. The growing number of new cases diagnosed each year is nearly equal to the number of deaths from this cancer. Worldwide, HCC is a leading cause of cancer-related deaths, as it is the fifth most common cancer and the third most important cause of cancer related death in men. Among various risk factors the two are prevailing: viral hepatitis, namely chronic hepatitis C virus is a well-established risk factor contributing to the rising incidence of HCC. The epidemic of obesity and the metabolic syndrome, not only in the United States but also in Asia, tend to become the leading cause of the long-term rise in the HCC incidence. Today, the diagnosis of HCC is established within the national surveillance programs in developed countries while the diagnosis of symptomatic, advanced stage disease still remains the characteristic of underdeveloped countries. Although many different staging systems have been developed and evaluated the Barcelona-Clinic Liver Cancer staging system has emerged as the most useful to guide HCC treatment. Treatment allocation should be decided by a multidisciplinary board involving hepatologists, pathologists, radiologists, liver surgeons and oncologists guided by personalized -based medicine. This approach is important not only to balance between different oncologic treatments strategies but also due to the complexity of the disease (chronic liver disease and the cancer) and due to the large number of potentially efficient therapies. Careful patient selection and a tailored treatment modality for every patient, either potentially curative (surgical treatment and tumor ablation) or palliative (transarterial therapy, radioembolization and medical treatment, i.e., sorafenib) is mandatory to achieve the best treatment outcome.

    Intraarterial injection of yttrium 90 microspheres (TheraSpheres) is used in the treatment of hepatocellular carcinoma (HCC). This article presents an analysis of the incidence of liver toxicities (liver-related events) and pretreatment factors associated with liver toxicities after TheraSphere treatment. Eighty-eight TheraSphere-treated patients with low 90-day mortality risk were selected for analysis, with liver toxicities coded with use of standard oncology criteria. Descriptive and inferential statistical methods were applied to estimate the incidence of liver toxicities and to evaluate the influence of liver radiation dose and various pretreatment factors on the risk of their occurrence. Sixty-eight liver toxicities occurred in 37 of the 88 patients (42%). Thirty-two patients (36%) experienced 50 liver toxicities after the first treatment and nine of 23 patients (39%) who received a second treatment experienced 18 liver toxicities. Pretreatment total bilirubin and liver radiation dose were found to be associated with the risk of at least one liver toxicity and with the time to first occurrence of a liver toxicity after first treatment. Pretreatment total bilirubin also was associated with liver toxicities after the second treatment. Most of the toxicities resolved; however, those that did not resolve were attributed to tumor progression or advancing cirrhosis. The risk of liver toxicities in patients with unresectable HCC treated with TheraSpheres increases with increasing pretreatment total bilirubin level and liver radiation dose to a maximum of 150 Gy for a single administration. The toxicities attributed to treatment resolved over time, and none of the patients studied had confirmed radiation-induced liver disease. Consequently, doses as high as 150 Gy on a single administration and as high as 268 Gy on repeated administrations were well tolerated.

    Full Text Available Local ablation therapy is considered as a conventional treatment option for patients with early stage hepatocellular carcinoma (HCC. Although radiofrequency (RF ablation is widely used for HCC, the use of cryoablation has been increasing as newer and safer cryoablation systems have developed. The thermodynamic mechanism of freezing and thawing used in cryoablation is the Joule-Thomson effect. Cryoablation destroys tissue via direct tissue destruction and vascular-related injury. A few recent comparative studies have shown that percutaneous cryoablation for HCCs is comparable to percutaneous RF ablation in terms of long term therapeutic outcomes and complications. Cryoablation has several advantages over RF ablation such as well visualization of iceball, no causation of severe pain, and lack of severe damage to great vessels and gallbladder. It is important to know the advantages and disadvantages of cryoablation compared with RF ablation for improvement of therapeutic efficacy and safety.

    Background: Our previous results for treatment of hepatocellular carcinoma (HCC) with proton beam therapy revealed excellent local control with low toxicity. Three protocols were used to avoid late complications such as gastrointestinal ulceration and bile duct stenosis. In this study, we examined the efficacy of these protocols. Methods and Materials: The subjects were 266 patients (273 HCCs) treated by proton beam therapy at University of Tsukuba between January 2001 and December 2007. Three treatment protocols (A, 66 GyE in 10 fractions; B, 72.6 GyE in 22 fractions; and C, 77 GyE in 35 fractions) were used, depending on the tumor location. Results: Of the 266 patients, 104, 95, and 60 patients were treated with protocols A, B, and C, respectively. Seven patients with double lesions underwent two different protocols. The overall survival rates after 1, 3 and 5 years were 87%, 61%, and 48%, respectively (median survival, 4.2 years). Multivariate analysis showed that better liver function, small clinical target volume, and no prior treatment (outside the irradiated field) were associated with good survival. The local control rates after 1, 3, and 5 years were 98%, 87%, and 81%, respectively. Multivariate analysis did not identify any factors associated with good local control. Conclusions: This study showed that proton beam therapy achieved good local control for HCC using each of three treatment protocols. This suggests that selection of treatment schedules based on tumor location may be used to reduce the risk of late toxicity and maintain good treatment efficacy.

    Transcatheter arterial chemoembolization (TACE) and subsequent percutaneous ethanol injection (PEI) was attempted in 8 patients with 9 hepatocellular carcinoma (HCCs) for complete tumor necrosis of HCCs less than 5 cm in greatest diameter. PEI was performed with 2-8 ml of absolute (99.9%) ethanol two weeks after TACE under CT or ultrasound guidance. For each patient PEI was done twice to four times within 4-10 days of each procedure. After completion of a series of PEI, follow up examination (range: 3 months-1.5 year period) was done with angiography, CT or ultrasound and correlated with serum alpha-fetoprotein (AFP) level. On follow up angiograms, the lesions completely disappeared or decreased in size without tumor vessels or staining in 5 of 6 patients. On follow up CT of 6 patients, the lipiodol-laden HCCs were surrounded by non-enhancing low density and the lesion sizes were slightly decreased or not changed. These are suggestive of necrosis of tumor itself and adjacent liver parenchyma. The tumors could not be detected on follow up ultrasound examination in 2 patients. Serum AFP was decreased in 7 patients and was well corresponded to the results of imaging modalities. The authors concluded that the combined TACE and PEI is an appropriate treatment for small HCCs having high surgical risks.

    Purpose: To assess the results of radiological treatment of patients with hepatocellular carcinoma (HCC) performed before orthotopic liver transplantation (OLT). Methods: Sixty-two transplanted patients with a total of 89 HCC nodules were studied; 50 lesions in 38 patients had been treated prior to OLT with transcatheter arterial chemoembolization (TACE; n= 29), percutaneous ethanol injection (PEI; n= 10), or combined therapy (TACE + PEI; n= 11). The induced necrosis was pathologically evaluated. The recurrence rate after OLT in the treated group of patients (n= 38) was compared with that in the non-treated group (n= 24). Results: After TACE, necrosis was complete in 7 of 29 lesions (24.1%), partial in 11 of 29 (37.9%), and absent in 11 of 29 (37.9%). After PEI, necrosis was complete in 8 of 10 lesions (80%), and partial in 2 of 10 (20%). Using combined therapy, necrosis was complete in 11 of 11 lesions (100%). Four of 24 untreated and 4 of 38 treated patients did not survive OLT from causes not related to the HCC; 3 of 20 non-treated patients (15%) and 4 of 34 treated patients (11.8%) had post-OLT recurrence (these last four patients had undergone only TACE and did not have tumor necrosis at pathological examination). Conclusion: TACE of HCC prior to OLT had no influence on the recurrence rate. PEI and combined therapy (TACE + PEI) may be recommended in patients awaiting OLT

    Objective: To discuss the clinical significance of anomalous origination of right gastric artery in interventional treatment for hepatocellular carcinoma (HCC). Methods: The dynamic enhanced CT scanning of the liver with a 64-slice spiral CT unit was performed in 72 HCC patients. In arterial phase, maximum intensity projection (MIP) and volume reconstruction technique (VRT) were used to observe the origin of the right gastric artery and its relationship with the hepatic artery. The findings were compared with the angiographic results. Results: Of the total 72 cases, the anomalous origin of the right gastric artery was found in 43 (59.8%). The anomalous origins of the right gastric artery included proper hepatic artery (n=19), left hepatic artery (n=17), gastroduodenal artery (n=4), right hepatic artery (n=2) and common hepatic artery (n=1). The results obtained from three-dimensional reconstruction were in good accordance with angiographic findings. Conclusion: The anomalously originated right gastric artery most commonly originates from the left hepatic artery. Three-dimensional reconstruction obtained from the 64-slice spiral CT scans can provide the clear and reliable images of the right gastric artery, which is very helpful for the interventional procedure.

    Metronomic capecitabine (MC) is a well-tolerated systemic treatment showing promising results in one retrospective study, as second-line therapy after sorafenib failure, in patients with hepatocellular carcinoma (HCC). 117 patients undergoing MC were compared to 112 patients, eligible for this treatment, but undergoing best supportive care (BSC) after sorafenib discontinuation for toxicity or HCC progression. The two groups were compared for demographic and clinical features. A multivariate regression analysis was conducted to detect independent prognostic factors. To balance confounding factors between the two groups, a propensity score model based on independent prognosticators (performance status, neoplastic thrombosis, causes of sorafenib discontinuation and pre-sorafenib treatment) was performed. Patients undergoing MC showed better performance status, lower tumor burden, lower prevalence of portal vein thrombosis, and better cancer stage. Median (95% CI) post-sorafenib survival (PSS) was longer in MC than in BSC patients [9.5 (7.5-11.6) vs 5.0 (4.2-5.7) months (p < 0.001)]. Neoplastic thrombosis, cause of sorafenib discontinuation, pre-sorafenib treatment and MC were independent prognosticators. The benefit of capecitabine was confirmed in patients after matching with propensity score [PSS: 9.9 (6.8-12.9) vs. 5.8 (4.8-6.8) months, (p = 0.001)]. MC lowered the mortality risk by about 40%. MC achieved better results in patients who stopped sorafenib for adverse events than in those who progressed during it [PSS: 17.3 (10.5-24.1) vs. 7.8 (5.2-10.1) months, (p = 0.035)]. Treatment toxicity was low and easily manageable with dose modulation. MC may be an efficient and safe second-line systemic therapy for HCC patients who discontinued sorafenib for toxicity or tumor progression.

    Full Text Available BACKGROUND: Endoplasmic reticulum stress (ER stress is generally activated in solid tumors and results in tumor cell anti-apoptosis and drug resistance. Paeonol (Pae, 2-hydroxy-4-methoxyacetophenone, is a natural product extracted from the root of Paeonia Suffruticosa Andrew. Although Pae displays anti-neoplastic activity and increases the efficacy of chemotherapeutic drugs in various cell lines and in animal models, studies related to the effect of Pae on ER stress-induced resistance to chemotherapeutic agents in hepatocellular carcinoma (HCC are poorly understood. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we investigated the effect of the endoplasmic reticulum (ER stress response during resistance of human hepatocellular carcinoma cells to doxorubicin. Treatment with the ER stress-inducer tunicamycin (TM before the addition of doxorubicin reduced the rate of apoptosis induced by doxorubicin. Interestingly, co-pretreatment with tunicamycin and Pae significantly increased apoptosis induced by doxorubicin. Furthermore, induction of ER stress resulted in increasing expression of COX-2 concomitant with inactivation of Akt and up-regulation of the pro-apoptotic transcription factor CHOP (GADD153 in HepG2 cells. These cellular changes in gene expression and Akt activation may be an important resistance mechanism against doxorubicin in hepatocellular carcinoma cells undergoing ER stress. However, co-pretreatment with tunicamycin and Pae decreased the expression of COX-2 and levels of activation of Akt as well as increasing the levels of CHOP in HCC cells. CONCLUSIONS/SIGNIFICANCE: Our results demonstrate that Pae reverses ER stress-induced resistance to doxorubicin in human hepatocellular carcinoma cells by targeting COX-2 mediated inactivation of PI3K/AKT/CHOP.

    Full Text Available Objective: To analyze the malignant degree of primary hepatocellular carcinoma after endostar combined with transcatheter arterial chemoembolization (TACE treatment. Methods: A total of 68 cases of patients with primary hepatocellular carcinoma treated in our hospital from September 2011 to December 2014 were enrolled for study and divided into observation group 34 cases and control group 34 cases according to different treatment methods. Control group received transcatheter arterial chemoembolization (TACE treatment, observation group received endostar combined with TACE treatment, and then differences in serum amino acid levels, micro RNA levels, levels of GP73, GPC3, GS, etc as well as levels of ChE, TBA and AFP were compared between two groups after treatment. Results: Serum aspartic acid, leucine and arginine levels of observation group after treatment were higher than those of control group, and αα-aminoadipic acid, methionine, β-alanine and 3-methylhistidine levels were lower than those of control group; relative values of serum miR-106b, miR-222 and miR-21 expression of observation group after treatment were lower than those of control group, and relative values of miR-199a and miR-122 expression were higher than those of control group; GP73, IL-17, IL-6, GPC3, GS and HSP70 levels of observation group after treatment were lower than those of control group, and endostatin level was higher than that of control group; ChE level of observation group after treatment was higher than that of control group, and TBA and AFP levels were lower than those of control group. Conclusion: Endostar combined with TACE treatment for patients with primary hepatocellular carcinoma can effectively inhibit tumor proliferation, invasion and other malignant processes and improve liver function, and it has positive clinical significance.

    Purpose: To investigate the rates of tumor response and local control in patients with recurrent small hepatocellular carcinoma (HCC) treated with hypofractionated radiotherapy (RT) as a salvage treatment and to evaluate treatment-related toxicities. Methods and Materials: Between 2006 and 2009, a total of 20 patients with recurrent small HCC were treated with hypofractionated RT after the failure of previous treatment. The eligibility criteria for hypofractionated RT were as follows: 1) HCC less than 5 cm, 2) HCC not adjacent to critical organs, 3) HCC without portal vein tumor thrombosis, and 4) less than 15% of normal liver volume that would be irradiated with 50% of prescribed dose. The RT dose was 50 Gy in 10 fractions. The tumor response was determined by CT scans performed 3 months after the end of RT. Results: The median follow-up period after RT was 22 months. The overall survival rates at 1 and 2 years were 100% and 87.9%, respectively. Complete response (CR) was achieved in seven of 20 lesions (35%) evaluated by CT scans performed 3 months after the end of RT. In-field local control was achieved in 85% of patients. Fourteen patients (70%) developed intra-hepatic metastases. Six patients developed grade 1 nausea or anorexia during RT, and two patients had progression of ascites after RT. There was no grade 3 or greater treatment-related toxicities. Conclusions: The current study showed a favorable outcome with respect to hypofractionated RT for small HCC. Partial liver irradiation with 50 Gy in 10 fractions is considered tolerable without severe complications.

Although combination of RFA with sorafenib, a molecular targeted agent, could attenuate the recurrence of HCC, application of this molecular targeted agent poses a heavy medical burden and oral administration of sorafenib also brings severe side effects. Materials and methods: In this study, we prepared an apatinib microcrystal formulation (Apa-MS that sustainably releases apatinib, a novel molecular targeted agent, for advanced HCC treatment. We injected apatinib solution or Apa-MS into subcutaneous HCC tumors. Results: It was found that Apa-MS exhibited slow apatinib release in vivo and in turn inhibited the epithelial–mesenchymal transition of HCC cells for extended time. Moreover, in rodent HCC model, Apa-MS enhanced the antitumor effect of RFA treatment. Conclusion: Based on these results, we conclude that Apa-MS, a slow releasing system of apatinib, allows apatinib to remain effective in tumor tissues for a long time and could enhance the antitumor effect of RFA on HCC. Keywords: apatinib microcrystals, radiofrequency ablation, sustained releasing behavior, long-acting efficiency

    During the past three decades, the incidence of hepatocellular carcinoma in the United States has tripled. The neuroendocrine character has been observed in some tumor cells within some hepatocellular carcinoma nodules and elevated serum chromogranin A also been reported in patients with hepatocellular carcinoma. The aim of this work was to investigate the role of serum concentration of chromogranin A in patients with hepatocellular carcinoma at different stages. The study population consisted of 96 patients (63 males and 33 females age range 52-84) at their first hospital admission for hepatocellular carcinoma. The control group consisted of 35 volunteers (20 males and 15 females age range 50-80). The hepatocellular carcinoma patients were stratified according the Barcelona-Clinic Liver Cancer classification. Venous blood samples were collected before treatment from each patients before surgery, centrifuged to obtain serum samples and stored at -80° C until assayed. The chromogranin A serum levels were elevated (> 100 ng/ml) in 72/96 patients with hepatocellular carcinoma. The serum levels of chromogranin A were significantly correlated (p<0.05) with alpha-fetoprotein. In comparison with controls, the hepatocellular carcinoma patients showed a significant increase (p<0.001) vs controls. The chromogranin A levels in the Barcelona staging of hepatocellular carcinoma was higher in stage D compared to stage C (p<0.01), to stage B (p<0.001), and to stage A (p<0.001). Molecular markers, such as chromogranin A, could be very useful tools for hepatocellular carcinoma diagnosis. However the molecular classification should be incorporated into a staging scheme, which effectively separated patients into groups with homogeneous prognosis and response to treatment, and thus serves to aid in the selection of appropriate therapy.

    To compare outcomes of radiation segmentectomy (RS) and segmental transarterial chemoembolization in treatment of unresectable, solitary hepatocellular carcinoma (HCC) ≤ 3 cm. From January 2012 to January 2016, 534 and 877 patients were treated with radioembolization and transarterial chemoembolization, respectively. A cohort of 112 (radiation segmentectomy [RS], 55; chemoembolization, 57) locoregional therapy-naïve patients with solitary HCC ≤ 3 cm without vascular invasion or metastasis was retrospectively identified and stratified according to baseline patient demographics, tumor characteristics, and laboratory values. Propensity score matching (PSM) was conducted using a nearest neighbor algorithm (1:1). Outcomes analyzed included laboratory toxicities, imaging response, time to secondary therapy (TTST), and overall survival. Before PSM, complete response (CR) rate was 81.2% for RS and 49.1% for chemoembolization (odds ratio 2.2; 95% confidence interval [CI], 1.4-3.3; P < .001). Median (95% CI) TTST after initial therapy was 246 days (135-250 d) in chemoembolization group and 700 days (308-812 d) in RS group (hazard ratio 0.71; 95% CI, 0.55-0.92; P = .009). Overall survival before PSM was not significantly different between the 2 groups (P = .29). Overall CR rate after PSM was 92.1% in RS group and 52.6% in chemoembolization group (P = .005). Median (95% CI) TTST after matching was 161 days (76-350 d) in chemoembolization group and 812 days (363-812 d) in RS group (P = .001). Overall survival after matching was not significantly different between the 2 groups (P = .71). RS results in improved imaging response and longer TTST compared with transarterial chemoembolization in treatment of early-stage HCC. Copyright © 2017 SIR. Published by Elsevier Inc.

    We evaluated the efficacy and toxicity of repeated high dose 3-dimensional conformal radiation therapy (3D-CRT) for patients with unresectable hepatocellular carcinoma. Between 1998 and 2011, 45 patients received hepatic re-irradiation with high dose 3D-CRT in Samsung Medical Center. After excluding two ineligible patients, 43 patients were retrospectively reviewed. RT was delivered with palliative or salvage intent, and equivalent dose of 2 Gy fractions for alpha/beta = 10 Gy ranged from 31.25 Gy 10 to 93.75 Gy 10 (median, 44 Gy 10 ). Tumor response and toxicity were evaluated based on the modified Response Evaluation Criteria in Solid Tumors criteria and the Common Terminology Criteria for Adverse Events (CTCAE) ver. 4.0. The median follow-up duration was 11.2 months (range, 4.1 to 58.3 months). An objective tumor response rate was 62.8%. The tumor response rates were 81.0% and 45.5% in patients receiving > or =45 Gy 10 and <45 Gy 10 , respectively (p = 0.016). The median overall survival (OS) of all patients was 11.2 months. The OS was significantly affected by the Child-Pugh class as 14.2 months vs. 6.1 months (Child-Pugh A vs. B, p < 0.001), and modified Union for International Cancer Control (UICC) T stage as 15.6 months vs. 8.3 months (T1-3 vs. T4, p = 0.004), respectively. Grade III toxicities were developed in two patients, both of whom received > or =50 Gy 10 . Hepatic re-irradiation may be an effective and tolerable treatment for patients who are not eligible for further local treatment modalities, especially in patients with Child-Pugh A and T1-3

    We evaluated the efficacy and toxicity of repeated high dose 3-dimensional conformal radiation therapy (3D-CRT) for patients with unresectable hepatocellular carcinoma. Between 1998 and 2011, 45 patients received hepatic re-irradiation with high dose 3D-CRT in Samsung Medical Center. After excluding two ineligible patients, 43 patients were retrospectively reviewed. RT was delivered with palliative or salvage intent, and equivalent dose of 2 Gy fractions for alpha/beta = 10 Gy ranged from 31.25 Gy{sub 10} to 93.75 Gy{sub 10} (median, 44 Gy{sub 10}). Tumor response and toxicity were evaluated based on the modified Response Evaluation Criteria in Solid Tumors criteria and the Common Terminology Criteria for Adverse Events (CTCAE) ver. 4.0. The median follow-up duration was 11.2 months (range, 4.1 to 58.3 months). An objective tumor response rate was 62.8%.

    Full Text Available Targeted biological therapies for hepatocellular cancer have shown minimal improvements in median survival. Multiple pathways to oncogenesis leading to rapid development of resistance to such therapies is a concern. Non-invasive radiofrequency field-induced targeted hyperthermia using nanoparticles is a radical departure from conventional modalities. In this paper we underscore the need for innovative strategies for the treatment of hepatocellular cancer, describe the central paradigm of targeted hyperthermia using non-invasive electromagnetic energy, review the process of characterization and modification of nanoparticles for the task, and summarize data from cell-based and animal-based models of hepatocellular cancer treated with non-invasive RF energy. Finally, future strategies and challenges in bringing this modality from bench to clinic are discussed.

    This study was designed to elucidate the significance of preoperative computed tomography during arterial portography (CTAP) in surgical treatment of hepatocellular carcinoma (HCC). Eighteen patients with HCC whose minute lesions had been pointed out by CTAP preoperatively (CTAP positive group) were compared with another eight patients with HCC having postoperative recurrence in a region at where no tumors had been detected by preoperative CTAP (CTAP negative group) for preoperative location of tumor and postoperative pattern of recurrence. In the CTAP positive group, 11 patients had recurrence and the remaining seven patients had not. Disease-free periods up to recurrences were 8.7 months in an average in the 11 CTAP positive patients and 16.6 months in the CTAP-negative group, showing a significantly shorter interval in the CTAP positive patients. In recurred cases from the CTAP positive group, tumors identified by imaging procedures other than CTAP were solitary in four and multiple in seven cases, while all solitary in non-recurred cases. In the recurred CTAP positive cases, actual recurrence occurred in the same segment where a tumor had been pointed out by CTAP alone in five out of six cases of solitary recurrence; or involved the same segment where CTAP detected tumor (s) in four out of five cases of multiple recurrence. It is indicated that the possibility of postoperative recurrence of HCC is high in cases having minute lesions visualized by CTAP alone in addition to multiple lesions visualized by imaging procedures other than CTAP. We think that periodical imaging methods including CTAP are required for HCC patients. (author)

  15. Reduction in non-protein respiratory quotient is related to overall survival after hepatocellular carcinoma treatment.

    Masaya Saito

    Full Text Available BACKGROUND: Transcatheter arterial chemoembolization (TACE is an effective treatment for hepatocellular carcinoma (HCC that can occasionally lead to the shortening of life expectancy. We aimed to make a new and more accurate prognostic model taking into account the course of disease after TACE. METHODOLOGY/PRINCIPAL FINDINGS: We performed a prospective cohort study involving 100 HCC patients who underwent TACE at Kobe University Hospital. Indirect calorimetry and blood biochemical examinations were performed before and 7 days after TACE. Time-dependent and time-fixed factors associated with 1-year mortality after TACE were assessed by multivariate analyses. A predictive model of 1-year mortality was established by the combination of odds ratios of these factors. Multivariate analyses showed that the ratio of non-protein respiratory quotient (npRQ (7 days after/before TACE and Cancer of Liver Italian Program (CLIP score were independent factors of 1-year mortality after TACE (p = 0.014 and 0.013, respectively. Patient-specific 1-year mortality risk scores can be calculated by summarizing the individual risk scores and looking up the patient-specific risk on the graph. CONCLUSIONS: The short-term reduction of npRQ was a time-dependent prognostic factor associated with overall survival in HCC patients undergoing TACE. CLIP score was a time-fixed prognostic factor associated with overall survival. Using the prediction model, which consists of the combination of time-dependent (npRQ ratio and time-fixed (CLIP score prognostic factors, 1-year mortality risk after TACE would be better estimated by taking into account changes during the course of disease.

    Successful treatment of hepatitis C virus (HCV) infection reduces the risk for hepatocellular carcinoma (HCC), but a risk remains. Current guidelines recommend continued HCC surveillance after sustained virologic response (SVR) has been achieved. This study aimed to investigate risk factors and incidence rates for HCC after SVR in HCV patients with pretreatment advanced liver disease (Metavir stage F3/F4). All patients with advanced liver disease successfully treated for HCV at Karolinska University Hospital during 1992-2013 (n = 399) were followed up for a median of 7.8 years. Data from national registries were used to minimize loss to follow-up. Incidence rates and hazard ratios (HRs) for development of HCC were calculated by Cox regression analysis. Seventeen patients developed HCC during 3366 person-years (PY) of follow-up. The HCC incidence rate was 0.95 (95% confidence interval [CI], .57-1.6) and 0.15 (95% CI, .05-.49) per 100 PY for patients with pretreatment F4 and F3, respectively. Patients with pretreatment cirrhosis and diabetes had a HR to develop HCC of 6.3, and an incidence rate of 7.9 per 100 PY (95% CI, 3.3-19) during the first 2 years of follow-up. The risk for HCC decreased significantly 2 years after SVR had been achieved. Diabetes mellitus and cirrhosis are strong risk factors for HCC development after SVR has been achieved. The risk to develop HCC diminishes significantly 2 years after SVR. Patients without cirrhosis have a low risk to develop HCC after SVR, and the benefit of HCC surveillance for this group is questionable. © The Author 2016.

    2013-01-01

    Background: Hepatocellular carcinoma (HCC) is a major health problem in Egypt as well as in many countries. Trans arterial chemo embolization (TACE) is a treatment modality applicable to locally advanced HCC beyond surgery or ablative therapies and is associated with survival improvements. The aim of this study was to assess the outcomes of TACE in our center over the past four years. Methods: This is a retrospective cohort study that included 221 patients with locally advanced HCC treated with TACE in a single center between the years 2007 and 2010. The median age was 57 years with male predominance. Liver cirrhosis, viral hepatitis and Bilharziasis were encountered in 64%, 31% and 8% of patients, respectively. Abdominal pain was the most common presenting symptom (67%). Most cases were diagnosed based on radiology (57%) with a TNM stage I or II (73%) and a median AFP value of 150 ng/m L. Results: 221 patients received 440 cycles of TACE with a median of 2 cycles per patient. Cisplatin and doxorubicin (50 mg per cycle, each) were the most commonly used drugs. Impaired liver function was the most common toxicity. Liver cell failure occurred in 17% of patients. An objective tumor response was achieved in 44% of cases. The median overall survival (OS) was 16 months (95% Cl, 13-19 months) and the median progression free survival (PFS) was 6 months (95% Cl, 4.3-7.8 months). Responding patients, Child-Pugh class A and patients receiving standard doses of chemotherapy had a significantly better OS than their counterparts. Only Child-Pugh class A was associated with significantly longer PFS (p < 0.001). Conclusion: TACE produces reasonable responses and fair survival rates in locally advanced HCC but with noticeable toxicities. Proper patients selection and prompt liver support are mandates for improving TACE outcomes.

    Epidemiology of hepatocellular carcinoma is changing worldwide. This study aimed at evaluating the changing scenario of aetiology, presentation, management and prognosis of hepatocellular carcinoma in Italy during the last 15 years. Retrospective analysis of the ITA.LI.CA (Italian Liver Cancer) database including 5192 hepatocellular carcinoma patients managed in 24 centres from 2000 to 2014. Patients were divided into three groups according to the date of cancer diagnosis (2000-2004, 2005-2009 and 2010-2014). The main results were as follows: (i) progressive patient aging; (ii) progressive expansion of non-viral cases and, namely, of "metabolic" hepatocellular carcinomas; (iii) increasing proportion of hepatocellular carcinoma diagnosed during a correct (semi-annual) surveillance programme; (iv) favourable cancer stage migration; (v) increased use of radiofrequency ablation to the detriment of percutaneous ethanol injection; (vi) improved outcomes of ablative and transarterial treatments; (vii) improved overall survival (adjusted for the lead time in surveyed patients), particularly after 2009, of both viral and non-viral patients presenting with an early- or intermediate-stage hepatocellular carcinoma. During the last 15 years several aetiological and clinical features of hepatocellular carcinoma patients have changed, as their management. The observed improvement of overall survival was owing both to the wider use of semi-annual surveillance, expanding the proportion of tumours that qualified for curative treatments, and to the improved outcome of loco-regional treatments. © 2016 John Wiley & Sons A/S.

    Objective: To study the helical CT signs of the hepatocellular carcinoma (HCC) after percutaneous microwave coagulation therapy (PMCT) and to evaluate the correlation between the helical CT signs and the therapeutic effect of HCC. Methods: The helical CT signs were analyzed in 22 cases with 26 lesions of the hepatocellular carcinoma that were treated with PMCT under ultrasonic guidance. Results: In 21 lesions, no enhancement was detected in the lesion border or inside the lesion at hepatic arterial phase (HAP) and portal venous phase (PVP). In 7 lesions, the slight or marked patchy enhancement was revealed in the surrounding liver of the lesions in HAP. In 5 lesions, nodular enhancement was found in the lesion border or inside the lesion in HAP. Conclusion: The dual-phase helical CT might be accurate in judging the therapeutic effect of HCC after PMCT. If no enhancement was showed in the lesions in the dual-phase helical CT, it indicated that no tumor survived. If slight or marked patchy pattern enhancement was revealed in the surrounding liver of the lesions in HAP, it was a normal reaction after PMCT. If nodular enhancement was found in the lesion border or inside the lesion in HAP, it indicated that the tumor partially survived

  20. Stereotactic body radiation therapy as an alternative treatment for small hepatocellular carcinoma.

    Full Text Available BACKGROUND: Even with early stage hepatocellular carcinoma (HCC, patients are often ineligible for surgical resection, transplantation, or local ablation due to advanced cirrhosis, donor shortage, or difficult location. Stereotactic body radiation therapy (SBRT has been established as a standard treatment option for patients with stage I lung cancer, who are not eligible for surgery, and may be a promising alternative treatment for patients with small HCC who are not eligible for curative treatment. MATERIALS AND METHODS: A registry database of 93 patients who were treated with SBRT for HCC between 2007 and 2009 was analyzed. A dose of 10-20 Gy per fraction was given over 3-4 consecutive days, resulting in a total dose of 30-60 Gy. The tumor response was determined using dynamic computed tomography or magnetic resonance imaging, which was performed 3 months after completion of SBRT. RESULTS: The median follow-up period was 25.6 months. Median size of tumors was 2 cm (range: 1-6 cm. Overall patients' survival rates at 1 and 3 years were 86.0% and 53.8%, respectively. Complete and partial tumor response were achieved in 15.5% and 45.7% of patients, respectively. Local recurrence-free survival rate was 92.1% at 3 years. Most local failures were found in patients with HCCs > 3 cm, and local control rate at 3 years was 76.3% in patients with HCC > 3 cm, 93.3% in patients with tumors between 2.1-3 cm, and 100% in patients with tumors ≤ 2 cm, respectively. Out-of-field intrahepatic recurrence-free survival rates at 1 and 3 years were 51.9% and 32.4%, respectively. Grade ≥ 3 hepatic toxicity was observed in 6 (6.5%. CONCLUSIONS: SBRT was effective in local control of small HCC. SBRT may be a promising alternative treatment for patients with small HCC which is unsuitable for other curative therapy.

    Purpose: To compare the safety of image-guided percutaneous cryoablation and radiofrequency ablation in the treatment of hepatocellular carcinoma in patients with cirrhosis. Materials and methods: This retrospective HIPAA-compliant study received institutional review board approval. Forty-two adult patients with cirrhosis underwent image-guided percutaneous ablation of hepatocellular carcinoma from 2003 to 2011. Twenty-five patients underwent 33 cryoablation procedures to treat 39 tumors, and 22 underwent 30 radiofrequency ablation procedures to treat 39 tumors. Five patients underwent both cryoablation and radiofrequency ablation procedures. Complication rates and severity per procedure were compared between the ablation groups. Potential confounding patient, procedure, and tumor-related variables were also compared. Statistical analyses included Kruskal–Wallis, Wilcoxon rank sum, and Fisher's exact tests. Two-sided P-values <0.05 were considered significant. Results: The overall complication rates, 13 (39.4%) of 33 cryoablation procedures versus eight (26.7%) of 30 radiofrequency ablation procedures and severe/fatal complication rates, two (6.1%) of 33 cryoablation procedures versus one (3.3%) of 30 radiofrequency ablation procedures, were not significantly different between the ablation groups (both P = 0.26). Severe complications included pneumothoraces requiring chest tube insertion during two cryoablation procedures. One death occurred within 90 days of a radiofrequency ablation procedure; all other complications were managed successfully. Conclusion: No significant difference was seen in the overall safety of image-guided percutaneous cryoablation and radiofrequency ablation in the treatment of hepatocellular carcinoma in patients with cirrhosis

    Objective: Metuximab is a specific monoclonal antibody F(ab') fragment targeted to the hepatocellular carcinoma (HCC) associated antigen of HAb18G/CD147. 131 I labeled metuximab has shown to be effective response on HCC in phase I/II trails. To evaluate the feasibility of 131 I-metuximab combined with transarterial chemoembolization (TACE) is the treatment of HCC, the authors estimated the radiation absorbed dose to organs. Methods: 131 I-metuximab (27.75 MBq/kg) and the mixture of anticancer drug and Lipiodol with interval 20 min later were administered to 21 patients with HCC via a transfemoral catheter. The pharmacokinetic and dosimetric data were collected by means of venous blood samples, urine collections, and 4 or 5 γ-scintigraphies (SPECT) over 7 d. The total amount of activity in percent of injected activity (% ID) of main organ and the total body were calculated by regions of interest (ROI). The cumulated activities were determined from integration of the time-% ID curves using the SPSS 12.0 software. Absorbed doses to organ and red marrow were estimated according to the medical internal radiation dose (MIRD) formalism and blood-based marrow estimation with a red marrow-to-blood activity concentration ratio. The tumor- to-no tumor ratio was calculated as well. Results: A mean administered activity was 1.89 GBq per session (range 1.47-2.23 GBq). SPECT scans showed the significant accumulation of the radioconjugate in liver tumor and faint uptake in other organs until 14 d. Organ absorbed dose (n=12): the total absorbed dose to liver, spleen, thyroid, lungs, kidney and total-body was (3.19 ± 1.01), (3.65 ± 2.41), (3.61 ± 2.40), (0.97 ± 0.23), (0.96 ± 0.35) and (0.57 ± 1.55) Gy, with (0.55 ± 0.09) Gy to the red marrow (n=7), respectively. From 2.88 ± 1.11 to 1.64 ± 0.39 were observed in tumor-to-liver ratio at 3 h to 168 h. Conclusion: Internal absorbed dose estimation based on MIRD formalism is not only to establish re- liable dose

    The aim of this article is to report the dosimetric and clinical findings in the treatment of primary hepatocellular carcinoma (HCC) with volumetric modulated arc therapy (VMAT, RapidArc). A total of 138 patients were investigated. Dose prescription ranged from 45-66 Gy. Most patients (88.4 %) presented AJCC stage III or IV and 83 % were N0-M0. All were classified as Barcelona Clinic Liver Cancer (BCLC) stage A-C. All patients were treated using 10 MV photons with single or multiple, coplanar or non-coplanar arcs, and cone-down technique in case of early response of tumors. The patients' median age was 66 years (range 27-87 years), 83 % were treated with 60 Gy (12 % at 45 Gy, 6 % at 66 Gy), 62 % with cone-down, 98 % with multiple arcs. The mean initial planning target volume (PTV) was 777 {+-} 632 cm{sup 3}; the mean final PTV (after the cone-down) was 583 {+-} 548 cm{sup 3}. High target coverage was achieved. The final PTV was V{sub 98%} > 98 %. Kidneys received on average 5 and 8 Gy (left and right), while the maximum dose to the spinal cord was 22 Gy; mean doses to esophagus and stomach were 23 Gy and 15 Gy, respectively. The average volume of healthy liver receiving more than 30 Gy was 294 {+-} 145 cm{sup 3}. Overall survival at 12 months was 45 %; median survival was 10.3 months (95 % confidence interval 7.2-13.3 months). Actuarial local control at 6 months was 95 % and 93.7 % at 12 months. The median follow-up was 9 months and a maximum of 28 months. This study showed from the dosimetric point of view the feasibility and technical appropriateness of RapidArc for the treatment of HCC. Clinical results were positive and might suggest, with appropriate care, to consider RapidArc as an additional therapeutic opportunity for these patients. (orig.)

    Hepatocellular carcinoma (HCC) is the leading cause of deaths in cirrhotic patients and the third cause of cancer related deaths. Most HCC are associated with well known underlying risk factors, in fact, HCC arise in cirrhotic patients in up to 90% of cases, mainly due to chronic viral hepatitis and alcohol abuse. The worldwide prevention strategies are conducted to avoid the infection of new subjects and to minimize the risk of liver disease progression in infected patients. HCC is a condition which lends itself to surveillance as at-risk individuals can readily be identified. The American and European guidelines recommended implementation of surveillance programs with ultrasound every six months in patient at-risk for developing HCC. The diagnosis of HCC can be based on non-invasive criteria (only in cirrhotic patient) or pathology. Accurately staging patients is essential to oncology practice. The ideal tumour staging system in HCC needs to account for both tumour characteristics and liver function. Treatment allocation is based on several factors: Liver function, size and number of tumours, macrovascular invasion or extrahepatic spread. The recommendations in terms of selection for different treatment strategies must be based on evidence-based data. Resection, liver transplant and interventional radiology treatment are mainstays of HCC therapy and achieve the best outcomes in well-selected candidates. Chemoembolization is the most widely used treatment for unresectable HCC or progression after curative treatment. Finally, in patients with advanced HCC with preserved liver function, sorafenib is the only approved systemic drug that has demonstrated a survival benefit and is the standard of care in this group of patients.

    Recently, three-dimensional (3D) printing has shown great interest in medicine, and 3D printed models may be rendered as part of the pre-surgical planning process in order to better understand the complexities of an individual's anatomy. The aim of this study is to investigate the feasibility of utilising 3D printed liver models as clinical tools in pre-operative planning for resectable hepatocellular carcinoma (HCC) lesions. High-resolution contrast-enhanced computed tomography (CT) images were acquired and utilized to generate a patient-specific 3D printed liver model. Hepatic structures were segmented and edited to produce a printable model delineating intrahepatic anatomy and a resectable HCC lesion. Quantitative assessment of 3D model accuracy compared measurements of critical anatomical landmarks acquired from the original CT images, standard tessellation language (STL) files, and the 3D printed liver model. Comparative analysis of surveys completed by two radiologists investigated the clinical value of 3D printed liver models in radiology. The application of utilizing 3D printed liver models as tools in surgical planning for resectable HCC lesions was evaluated through kappa analysis of questionnaires completed by two abdominal surgeons. A scaled down multi-material 3D liver model delineating patient-specific hepatic anatomy and pathology was produced, requiring a total production time of 25.25 hours and costing a total of AUD $1,250. A discrepancy was found in the total mean of measurements at each stage of production, with a total mean of 18.28±9.31 mm for measurements acquired from the original CT data, 15.63±8.06 mm for the STL files, and 14.47±7.71 mm for the 3D printed liver model. The 3D liver model did not enhance the radiologists' perception of patient-specific anatomy or pathology. Kappa analysis of the surgeon's responses to survey questions yielded a percentage agreement of 80%, and a κ value of 0.38 (P=0.24) indicating fair agreement. Study

    A 59-year-old man with metastatic an esophageal tumor from hepatocellular carcinoma (HCC) presented with progressive dysphagia. He had undergone liver transplantation for HCC three and a half years prevously. At presentation, his radiological and endoscopic examinations suggested a submucosal tumor in the lower esophagus, causing a luminal stricture. We performed complete resection of the esophageal metastases and esophagogastrostomy reconstruction using the da Vinci robotic system. Recovery was uneventful and he was been doing well 2 mo after surgery. α-fetoprotein level decreased from 510 ng/mL to 30 ng/mL postoperatively. During the follow-up period, he developed a recurrent esophageal stricture at the anastomosis site and this was successfully treated by endoscopic esophageal dilatation. PMID:21765971

    Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide and the third leading cause of cancer deaths. microRNAs (miRNAs) are evolutionary conserved small non-coding RNA that negatively regulate gene expression and protein translation. Recent evidences have shown that they are involved in many biological processes, from development and cell-cycle regulation to apoptosis. miRNAs can behave as tumor suppressor or promoter of oncogenesis depending on the cellular function of their targets. Moreover, they are frequently dysregulated in HCC. In this review we summarize the latest findings of miRNAs regulation in HCC and their role as potentially diagnostic and prognostic biomarkers for HCC. We highlight development of miRNAs as potential therapeutic targets for HCC.

    Sorafenib, an oral multikinase inhibitor, is the only systemic agent proven to be effective in patients with hepatocellular carcinoma (HCC). There are no approved second line systemic therapies in patients who have had disease progression on or are not eligible to sorafenib. We describe two cases of unresectable HCC that were treated with low, "metronomic" doses of capecitabine. In the first patient, capecitabine was used after sorafenib failure. In the second case, treatment with capecitabine was attempted since the patient was considered not eligible for sorafenib due to spontaneous hepatic bleeding of a large HCC lesion. Treatment was effective and well tolerated in both patients with long-lasting objective responses. Lacking established second-line therapy, metronomic capecitabine may be a valid alternative in the treatment of HCC patients who are judged not eligible for sorafenib or those having progression disease on sorafenib.

    Full Text Available Hepatocellular carcinoma (HCC is one of the most common malignant tumors worldwide, and traditional surgery and chemotherapy provide limited benefit. Sorafenib, a multikinase inhibitor, was proved effective for advanced HCC in phase III clinical trial, which was a breakthrough in the treatment of HCC. In recent years, the studies on sorafenib combined with other therapies in the treatment of HCC have been conducted around the world, and inspiring results have been seen. The research advances in sorafenib combined with orthotopic liver transplantation, radiofrequency ablation, and transarterial chemoembolization in the treatment of HCC are summarized. It is thought that sorafenib combined with other anticancer therapies is expected to become a new approach of targeted therapy of HCC.

    (1) Microspheres containing radioactive yttrium-90 (90Y) are infused into the hepatic artery. These deliver high doses of ionizing radiation to inoperable hepatocellular carcinoma, the most common type of primary liver cancer. (2) Limited evidence from several case series indicates that palliative therapy with 90Y microspheres may reduce tumour size and increase survival time. (3) In some patients, 90Y treatment may result in enough tumour reduction to permit liver resection or transplantation. (4) While 90Y microsphere therapy is generally well tolerated, major complications and several treatment-related deaths have occurred. Improved patient selection criteria and technical changes to microsphere delivery have reduced the risks of complications and death. (5) Patient selection and the technical aspects of 90Y microsphere treatment are complex and require the coordinated expertise of a multidisciplinary team.

    During the proliferation and metastasis, the tumor cells prefer glycolysis (Warburg effect), but its exact mechanism remains largely unknown. In this study, we demonstrated that phosphoglycerate kinase 1 (PGK1) is an important enzyme in the pathway of metabolic glycolysis. We observed a significant overexpression of PGK1 in hepatocellular carcinoma tissues, and a correlation between PGK1 expression and poor survival of hepatocellular carcinoma patients. Also, the depletion of PGK1 dramatically reduced cancer cell proliferation and metastasis, indicating an oncogenic role of PGK1 in liver cancer progression. Further experiments showed that PGK1 played an important role in MYC -induced metabolic reprogramming, which led to an enhanced Warburg effect. Our results revealed a new effect of PGK1, which can provide a new treatment strategy for hepatocellular carcinoma, as PGK1 is used to indicate the prognosis of hepatocellular carcinoma (HCC).

    Hepatocellular carcinoma is one of the main important causes of cancer-related death and its mortality is increasingly worldwide. In Europe, alcohol abuse accounts for approximately half of all liver cancer cases and it will become the leading cause of hepatocellular carcinoma in the next future with the sharp decline of chronic viral hepatitis. The pathophysiology of alcohol-induced carcinogenesis involves acetaldehyde catabolism, oxidative stress and chronic liver inflammation. Genetic background plays also a significant role and specific patterns of gene mutations in alcohol-related hepatocellular carcinoma have been characterized. Survival is higher in patients who undergo specific surveillance programmes than in patients who do not. However, patients with alcohol cirrhosis present a significantly greater risk of liver decompensation than those with cirrhosis due to other aetiologies. Furthermore, the adherence to screening program can be suboptimal. Liver transplant for patients with Milan-in hepatocellular carcinoma represents the best possible treatment in case of tumour recurrence/progression despite loco-regional or surgical treatments. Long-term result after liver transplantation for alcohol related liver disease is good. However, cardiovascular disease and de novo malignancies can significantly hamper patients' survival and should be carefully considered by transplant team. In this review, we have focused on the evolution of alcohol-related hepatocellular carcinoma epidemiology and risk factors as well as on liver transplantation in alcoholic patients with and without hepatocellular carcinoma.

    Full Text Available Jörg Trojan, Oliver Waidmann Medizinische Klinik 1, Universitätsklinikum Frankfurt, Germany Abstract: Sorafenib is still the only systemic drug approved for the treatment of advanced hepatocellular carcinoma (HCC. In recent years, several investigational agents mainly targeting angiogenesis failed in late-phase clinical development due to either toxicity or lack of benefit. Recently, data of the RESORCE trial, a placebo-controlled Phase III study that evaluated the efficacy and safety of regorafenib in patients with HCC and documented disease progression after systemic first-line treatment with sorafenib, were presented at the ESMO World Congress on Gastrointestinal Cancer, 2016. Regorafenib treatment resulted in a 2.8-month survival benefit compared to placebo (10.6 months vs 7.8 months. Side effects were consistent with the known profile of regorafenib. The approval of regorafenib for this indication is expected in 2017. Further candidate agents in Phase III evaluation for second-line treatment of patients with HCC are the MET inhibitors tivantinib and cabozantinib, the vascular endothelial growth factor receptor-2 antibody ramucirumab, and the programmed death receptor-1 (PD-1 blocking antibody pembrolizumab. Furthermore, results from two first-line trials with either the tyrosine kinase inhibitor lenvatinib or the PD-1 antibody nivolumabin in comparison to sorafenib are awaited in the near future and might further change the treatment sequence of advanced HCC.

    Purpose: Virtual CT sonography using magnetic navigation provides cross sectional images of CT volume data corresponding to the angle of the transducer in the magnetic field in real-time. The purpose of this study was to clarify the value of this virtual CT sonography for treatment response of radiofrequency ablation for hepatocellular carcinoma. Patients and methods: Sixty-one patients with 88 HCCs measuring 0.5–1.3 cm (mean ± SD, 1.0 ± 0.3 cm) were treated by radiofrequency ablation. For early treatment response, dynamic CT was performed 1–5 days (median, 2 days). We compared early treatment response between axial CT images and multi-angle CT images using virtual CT sonography. Results: Residual tumor stains on axial CT images and multi-angle CT images were detected in 11.4% (10/88) and 13.6% (12/88) after the first session of RFA, respectively (P = 0.65). Two patients were diagnosed as showing hyperemia enhancement after the initial radiofrequency ablation on axial CT images and showed local tumor progression shortly because of unnoticed residual tumors. Only virtual CT sonography with magnetic navigation retrospectively showed the residual tumor as circular enhancement. In safety margin analysis, 10 patients were excluded because of residual tumors. The safety margin more than 5 mm by virtual CT sonographic images and transverse CT images were determined in 71.8% (56/78) and 82.1% (64/78), respectively (P = 0.13). The safety margin should be overestimated on axial CT images in 8 nodules. Conclusion: Virtual CT sonography with magnetic navigation was useful in evaluating the treatment response of radiofrequency ablation therapy for hepatocellular carcinoma.

    With the development of gray scale ultrasonography, detection and evaluation of hepatic parenchymal disease including space occupying lesion are easily performed and frequently used in the world. Thrity five cases of histopathologically proven and ultrasonographically suggested hepatocellular carcinoma are retrospectively studied. The results were as follows; 1. Ultrasonographic findings of hepatocellular carcinoma show hyperechoic pattern in 22 cases (63%), hypoechoic pattern in 2 cases (6%), and mixed pattern in 11 cases (31%). 2. The margin of tumor is ill-defined in 19 cases (54%) and well defined in16 cases (46%). 3. The size of tumor by sonographic measurement was large than 5 cm in diameter in 33 cases (94%). 4. The number of tumor is solitary in 19 cases and multiple in 16 cases. The sites of involved lobe were right lobe in 22 cases (63%), left lobe in 2 cases (6%), and both lobes in 11 cases (31%). 5. Associated sonographic findings were hepatomegaly with focal contour change in 25 cases (71%), splenomegaly in 16 cases (46%), cirrhosis of liver in 15 cases (43%), ascites in 11 cases (31%) and tumoral thrombosis in portal vein in 8 cases (23%). 6. The sex ratio is 6 : 1 male predominence and the age ranges from 32 to 76 years with highest incidence in 5th and 6th decades.

    This study retrospectively reviews the characteristic bone scintigraphic findings in 18 patients with hepatocellular carcinoma (HCC) following treatment with high-intensity focused ultrasound (HIFU). A potential complication of HIFU is damage to the tissues along the path of the ultrasound beam and structures superficial to the lesion of interest. Patients with hepatocellular carcinoma who underwent a bone scan between 1st December 2005 and 31st December 2011 were considered for this study. Among these patients, only those who had bone scans after the HIFU treatment were included. The time between HIFU treatment and bone scans, HIFU energy, HCC sites, tumour sizes and related radiological findings were evaluated. In total, 20 bone scans of 18 patients were reviewed. Of these scans, two patients were normal; three patients showed decreased uptake, four patients showed increased uptake and nine patients showed mixed uptakes of the bony tracer in their rib cages. The defects were located in the anterior, lateral, anterolateral or posterolateral aspects of the rib cage. The majority of those cold defects were in the right anterior rib cages. SPECT/CT was used to localise the decreased uptake in ribs. The magnetic resonance imaging in individual patients invariably showed ill-defined rim enhancement along the right chest wall, signifying chest wall injury. The results showed that tissue ablation using HIFU caused tissue injury along the pathway of high-intensity ultrasound beams. The harm to tissues is presented as photopenic area on the rib cages due to necrosis or hot spots due to rib fractures in the bone scan. Since these cold defects are subtle, they are easily overlooked or mistaken as aggressive bony metastasis.

    On April 27, 2017, the U.S. Food and Drug Administration approved regorafenib for the treatment of patients with advanced hepatocellular carcinoma (HCC) who had previously been treated with sorafenib. Approval was based on the results of a single, randomized, placebo-controlled trial (RESORCE) that demonstrated an improvement in overall survival (OS). Patients were randomly allocated to receive regorafenib160 mg orally once daily or matching placebo for the first 21 days of each 28-day cycle. The trial demonstrated a significant improvement in OS (hazard ratio [HR] = 0.63; 95% confidence interval [CI], 0.50-0.79, p  regorafenib arm and 7.8 months in the placebo arm. A statistically significant improvement in progression-free survival (PFS) based on modified RECIST for HCC [Semin Liver Dis 2010;30:52-60] (HR = 0.46; 95% CI, 0.37-0.56, p  regorafenib and placebo arms, respectively. The overall response rate, based on modified RECIST for HCC, was 11% in the regorafenib arm and 4% in the placebo arm. The toxicity profile was consistent with that observed in other indications; the most clinically significant adverse reactions were palmar-plantar erythrodysesthesia, diarrhea, and hypertension. Based on the improvement in survival and acceptable toxicity, a favorable benefit-to-risk evaluation led to approval for treatment of patients with advanced HCC. Regorafenib is the first drug approved by the U.S. Food and Drug Administration for the treatment of hepatocellular carcinoma that has progressed on sorafenib and is expected to become a standard of care for these patients.

    Purpose: To evaluate the clinical effectiveness of self-expandable metallic stents in seven patients with malignant gastroduodenal obstruction caused by inoperable hepatocellular carcinoma (HCC). Methods: Seven patients with gastroduodenal obstruction caused by advanced HCC underwent metallic stent placement from 2003 to 2010. These patients had total dysphagia (n = 5) or were able to eat only liquids (n = 2) before stent placement. Patients had Eastern Cooperative Oncology Group performance scores of 2 or 3, and Child-Pugh classification B or C. Results: Stent placement was technically successful in all seven patients (100%) and clinically successful in six (86%). Five patients could eat a soft diet, and one patient tolerated regular diet after stent placement. Stent-related obstructive jaundice occurred in one patient. One patient had hematemesis 11 days after stent placement. Overall mean survival was 51 days (range, 10-119 days). Stent patency was preserved in six patients with clinical success until death. Conclusion: Placement of a covered self-expandable metallic stent may offer good palliation in patients with gastroduodenal obstruction due to advanced HCC.

    Full text: In this paper we present our early experience with a new radio-conjugate, namely rhenium-188 HDD Lipiodol (Re-188 lipiodol). Imported radiopharmaceuticals are generally expensive, particularly for developing countries. A Tungsten (W-188-Re 188) generator obtained from ORNL (Oak Ridge National Laboratory, Tennessee, USA) allows us on-site production of a beta emitting therapeutic isotope (Re-188) for up to 6 months from a single generator. The objectives of this study were to establish the safety of trans-arterial Re-188 lipiodol in patients with inoperable HCC, and determine the adverse effects and efficacy for this radio-conjugate treatment in a multi-center study of patients with advanced HCC. A multi-center study was sponsored by the International Atomic Energy Agency (Vienna) to assess the safety and efficacy of trans-arterial Re-188 HDD conjugated lipiodol (radio-conjugate) in the treatment of patients with inoperable hepatocellular carcinoma (HCC), The radio-conjugate was prepared by using a HDD (4-hexadecyl 1-2, 9, 9-tetramethyl-4, 7-diaza-1, 10-decanethiol) kit developed in Korea, and lipiodol. Over a period of eighteen months seventy patients received at least one treatment of radio-conjugate. Some patients were re-treated if there was no evidence of disease progression. The level of radio-conjugate administered was based on radiation-absorbed dose to critical normal organs, calculated following a 'scout' dose of radio-conjugate. The organs at greatest risk for radiation toxicity are the normal liver, the lung and the bone marrow. A specially designed spreadsheet was used to determine maximum tolerated activity (MTA), defined as the amount of radioactivity calculated to deliver no more than 12 Gray (Gy) to lungs, or 30 Gy to liver, or 1.5 Gy to bone marrow. These doses have been found to be safe in multiple trials using external beam therapy and systemically administered radiopharmaceuticals. Patients were followed for at least twelve weeks

    The authors report of a multicenter study on the diagnosis and interventional therapy of hepatocellular carcinoma (HCC).The first aim -diagnostic - was to evaluate the sensitivity of 4 imaging techniques, namely ultrasonography (US), Computed Tomography (CT), digital arteriography (DSA) and Lipiodol CT (LCT), in hepatocellular carcinoma detection. The accuracy of these techniques was also investigated in tumor staging, which is important for treatment planning.The second aim - treatment - consisted in assessing the therapeutic efficacy of intraarterial chemoembolization (CEAT) versus percutaneous ethanol injection (PEI) in non advanced hepatocellular carcinoma and of intraarterial chemoembolization versus no treatment (NT) in advanced hepatocellular carcinoma. Treatment efficacy was evaluated with the following randomized protocols

    The articles concerning intensive effect and progress of interventional therapy for hepatocellular carcinoma (HCC) recurrence were comprehensively reviewed. Along with unceasing abundance of all interventional methods (including transcatheter arterial chemoemblization (TACE), percutaneous dehydrated ethanol injection, radio frequency ablation, percutaneous microwave therapy, argon-helium cryoablation, high-intensity focused ultrasound and radionuclide interventional therapy, etc), combined interventional therapies mainly TACE were increasingly appreciated in postoperative HCC recurrence, but still have to be further standardized. With further emerging and maturing of new technologies, such as antiangiogenesis, gene therapy and targeted therapy on HCC metastatic and recurrence specific cycle; the effect of combined therapy will be further promoted. Interventional therapy will play an important role in the prevention and treatment of postoperative HCC recurrence in the foreseen furture. (authors)

    PurposeTo assess radiofrequency (RF) ablation efficacy, as well as the patency of transjugular intrahepatic portosystemic shunts (TIPSs), in patients with hepatocellular carcinoma (HCC).Materials and MethodsRetrospective database review of patients with pre-existing TIPS undergoing RF ablation of HCC was conducted over a 159-month period ending in November 2013. TIPS patency pre- and post-RF ablation was assessed by ultrasound, angiography, and/or contrast-enhanced CT or MRI. Patient demographics and immediate post-RF ablation outcomes and complications were also reviewed.Results19 patients with 21 lesions undergoing 25 RF ablation sessions were included. Child-Pugh class A, B, and C scores were seen in 1, 13, and 5 patients, respectively. Eleven patients (58 %) ultimately underwent liver transplantation. Immediate technical success was seen in all ablation sessions without residual tumor enhancement (100 %). No patients (0 %) suffered liver failure within 1 month of ablation. Pre-ablation TIPS patency was demonstrated in 22/25 sessions (88 %). Of 22 cases with patent TIPS prior to ablation, post-ablation patency was demonstrated in 22/22 (100 %) at immediate post-ablation imaging and in 21/22 (95 %) at last follow-up (1 patient was incidentally noted to have occlusion 31 months later). No immediate complications were observed.ConclusionAblation efficacy was similar to the cited literature values for patients without TIPS. Furthermore, TIPS patency was preserved in the majority of cases. Patients with both portal hypertension and HCC are not uncommonly encountered, and a pre-existing TIPS does not appear to be a definite contraindication for RF ablation

    From March 1977 to July 1979, 69 cases of angiograms of hepatocellular carcinoma were observed in Seoul National University Hospital. The findings of selective celiac and/or hepatic arteriography in total 69 cases of confirmed hepatocellular carcinoma, with clinical and laboratory findings, were analyzed. The summarized results are as follows; 1. Among 69 cases od hepatoma, 62 were male and 7 were female with sex ratio of 8.9 : 1. Peak incidence is 5th to 7th decades (72.5%). Epigastric pain, indigestion, and palpable mass in right upper quadrant were common symptoms and sign. Laboratory findings showed elevated serum alkaline phosphatase more than 5 Bodansky unit in 75.4%. Alpha-feto protein was positive in 65.2% of all the patients. 2 All 69 cases were classified into 31 cases of massive type, 22 cases of diffuse type, and 16 cases of nodular type, in accordance with angiographic gross anatomy. The frequency of angiographic findings were hypervascularities and tumor vessels (100%), tumor stainings (98.5%), arteriovenous shunt (71.0%), displacement of intrahepatic arteries (66.7%), vascular lakes and channel (59.4%). Encasement of hepatic artery and portal vein regurgitation was respectively 4 cases. Tumor mass in portal vein were 6 cases and tumor mass in hepatic vein was 1 case. 3. Intraarterial infusion of 5-FU was performed in 15 hepatoma patients, and the results were that angiographic improvement was demonstrated in 3 cases, no improvement in 8 cases, and incomplete infusion in 4 cases. 4. The selective celiac and/or hepatic angiograms are excellent diagnostic tools as well as therapeutic management for intraarterial infusion of anticancerous drugs.

    With Development of Computed Tomography, detection of the Hepatocellular Carcinoma are easily performed and frequently used in the world. During 15 months, from December 1985 to February 1987, 59 patients with hepatocellular carcinoma were evaluated with computed tomography in department of radiology at Wallace Memorial Baptist Hospital. The results were as follow: 1. The most prevalent age group was 5th to 7th decades, male to female ratio was 4.9:1. 2. Classification with incidence of computed tomographic appearance of the hepatocellular carcinoma were solitary type 28 cases (48%), multinodular type 24 cases (40%), and diffuse type 7 cases (12%), Association with liver cirrhosis was noted in 22 cases (38%). 3. Inhomogenous internal consistency of hepatocellular carcinoma due to central necrosis were 35 cases (60%). Portal vein invasion by hepatocellular carcinoma was noted in 15 cases (25%), and particularly most common in diffuse type 4 cases (55%). 4. On precontrast scan, all hepatocellular carcinoma were seen as area of low density except for 3 cases(0.5%) of near isodensity which turned out to be remarkable low density on postcontrast scan. 5. In solitary type, posterior segment of right lobe was most common site of involvement 12 cases (43%). In diffuse type, bilobar involvement was most common, 6 cases (85%)

    Full Text Available BACKGROUND: Hepatocellular carcinoma (HCC is a common cancer associated with a poor prognosis. Bevacizumab is a monoclonal antibody that binds vascular endothelial growth factor, a mediator of tumor angiogenesis. Bevacizumab is currently under investigation as treatment for HCC. We performed a systematic review of the efficacy and safety of bevacizumab for the treatment of advanced HCC. METHODS: PubMed, the Cochrane Library, and Google Scholar were searched using the terms "bevacizumab AND hepatocellular carcinoma AND (advanced OR unresectable". Phase II trials of bevacizumab for the treatment of advanced HCC were included. Outcomes of interest included progression-free and overall survival (PFS and OS, tumor response, and toxicities. RESULTS: A total of 26 records were identified. Of these, 18 were excluded. Hence, eight trials involving 300 patients were included. Bevacizumab was given as monotherapy (n = 1 trial or in combination with erlotinib (n = 4 trials, capecitabine (n = 1 trial, capecitabine+oxaliplatin (n = 1 trial, or gemcitabine+oxaliplatin (n = 1 trial. Most trials (five of eight reported median PFS and OS between 5.3 months and 9.0 months and 5.9 and 13.7 months, respectively. The disease control rate was consistent in five of eight trials, ranging from 51.1% to 76.9%. The response and partial response rates ranged from 0 to 23.7%, but were around 20% in four trials. Only one patient had a complete response. Frequently reported Grade 3/4 toxicities were increased aspartate transaminase/alanine transaminase (13%, fatigue (12%, hypertension (10%, diarrhea (8%, and neutropenia (5%. Thirty patients experienced gastrointestinal bleeding (grade 1/2 = 18, grade 3/4 = 12, typically due to esophageal varices. CONCLUSIONS: Bevacizumab shows promise as an effective and tolerable treatment for advanced HCC. The reported efficacy of bevacizumab appears to compare favorably with that of sorafenib, the only currently

    Objective: To show the computed tomography (CT) usefulness after treatment with transcatheter arterial quimioembolization and radiofrequency ablation of hepatocellular carcinoma. Material and methods: In a period between march 2006 to april 2008 a total of 90 patient presenting 148 nodular lesions with diagnosis of hepatocellular carcinoma were controlled with triphasic CT. All the lesions were treated with minimally invasive procedure. For the treatment, the patients were classified in two groups following Milan criteria. The first group, constituted by 75 patients with 109 nodules, was treated with quimioembolization. The second group, of 15 patients with 25 nodules, was treated with radiofrequency ablation. In our population, a subgroup of 10 patients was treated with both methods. Results: Of 90 patients after CT control on a month, 3 months and for each 3 months during 2 years, on 63 cases (70%) was observed homogeneous accumulation of iodized oil, partial defect without enhancement or absence of enhancement on treated lesions. In these patients a new treatment after initial one was not performed. The remaining 27 patients (30%) underwent new treatment because we founded partial defect or absence of iodized oil with enhancement or peripheral enhancement on arterial phase in treated lesions. In this last group, 16 treated patients (17.7%) had new nodular enhancement on the remaining hepatic parenquimal. Conclusion: The CT unenhanced and the arterial phase on a month and for each 3 months, allow monitoring the effectiveness, residual disease and/or relapse of hepatocellular carcinoma after minimally invasive treatment.

    Objective: To explore the efficacy of Argon-Helium cryotherapy system (AHCS) after transarterial chemoembolization (TACE) in treating the large hepatocellular carcinoma (HCC) with diameter over 10 cm. Methods: Forty-eight HCC patients were randomly divided into therapy group (n=26) and control group (n=22), and patients in the therapy group were treated with AHCS [(Cryocare) TM Surgical System] 4 weeks after TACE. Tumor size ranged from 10 to 13 cm. All tumors were hypervascular with Child A in 38 cases and Child B in 10 cases. AFP was positive in 40 cases and negative in 8. Reexamination included pathology, tumor marker, T-lymphocyte subgroup, ultrasound, CT, or MRI. Necrosis rate was calculated with Cavalieri theory. Numerical rating scale (NRS) for pain evaluation and EORTC QLQ-C30 for life quality evaluation were performed. Results: Technical success rate was 100%. Follow-up time varied from 6 to 14 months, and follow-up rate was 100%. Average neoplasm necrosis rate was 8.07% after TACE, and 28.65% after AHCS. Tumor marker significantly deceased after AHCS. The necrosis after AHCS was more significant than that after TACE alone. AST and ALT deteriorated for 2 weeks after TACE and for 1 week after AHCS. Local pain 48 hours after AHCS was the only more serious side effect than after TACE. Immunological function was significantly suppressed after TACE. CD 3 + , CD 4 + , and NK increased after AHCS, and abnormal distribution was corrected. Coagulative necrosis was founded in the tumor target area pathologically. Quality of life increased according EORTC QLQ-C30 results after AHCS. No severe complication occurred. Conclusion: AHCS after TACE can reduce tumor load in short term, and it can improve cellular immunity, ameliorate the liver function, increase the quality of life, and make satisfactory effect in the near future. The key point to increase therapeutic efficacy is the embolization of blood vessel and control of heat sink effect by TACE. Interventional

    There is an urgent need for novel effective treatment for hepatocellular carcinoma (HCC). Oncolytic viruses (OVs) not only directly lyse malignant cells, but also induce potent antitumour immune responses. The potency and precise mechanisms of antitumour immune activation by attenuated measles virus remain unclear. In this study, we investigated the potency of the measles virus vaccine strain Edmonston (MV-Edm) in improving adoptive CD8 + NKG2D + cells for HCC treatment. We show that MV-Edm-infected HCC enhanced the antitumour activity of CD8 + NKG2D + cells, mediated by at least three distinct mechanisms. First, MV-Edm infection compelled HCC cells to express the specific NKG2D ligands MICA/B, which may contribute to the activation of CD8 + NKG2D + cells. Second, MV-Edm-infected HCC cells stimulated CD8 + NKG2D + cells to express high level of FasL resulting in enhanced induction of apoptosis. Third, intratumoural administration of MV-Edm enhanced infiltration of intravenously injected CD8 + NKG2D + cells. Moreover, we found that MV-Edm and adoptive CD8 + NKG2D + cells, either administered alone or combined, upregulated the immune suppressive enzyme indoleamine 2,3-dioxygenase 1 (IDO1) in HCC. Elimination of IDO1 by fludarabine enhanced antitumour responses. Taken together, our data provide a novel and clinically relevant strategy for treatment of HCC.

    Full Text Available Hepatocellular carcinoma (HCC is increasing in incidence, and the associated mortality rate remains among the highest. For advanced HCC, sorafenib has been shown to slightly prolong survival, and regorafenib and nivolumab, both recently approved by the United States Food and Drug Administration (FDA, may produce clinical benefits to a limited extent. Systemic chemotherapy has been shown to produce a modest response, but there is no clinically valid biomarker that can be used to predict which patients may benefit. In this case study, we present two patients with metastatic HCC, they received systemic treatment using capecitabine, oxaliplatin, and either bevacizumab or sorafenib. The tumor response to treatment was determined by the progression-free survival (PFS. Molecular profiling of the tumors showed differential expression of biochemical markers and different mutational status of the TP53 and β-catenin (CTNNB1 genes. We hypothesize that the PFS correlates with the tumor molecular profiles, which may be predictive of the therapeutic response to systemic chemotherapy. Further investigation is indicated to correlate tumor biomarkers and treatment responses, with the objective of personalizing the therapies for patients with advanced HCC.

    Background: The objective of this study is to assess the outcome of the patients treated for hepatocellular carcinoma (HCC) in a General Surgery and Liver Transplantation Center. Methods: This retrospective study includes 844 patients diagnosed with HCC and surgically treated with curative intent methods. Curative intent treatment is mainly based on surgery, consisting of liver resection (LR), liver transplantation (LT). Tumor ablation could become the choice of treatment in HCC cases not manageable for surgery (LT or LR). 518 patients underwent LR, 162 patients benefited from LT and in 164 patients radiofrequency ablation (RFA) was performed. 615 patients (73%) presented liver cirrhosis. Results: Mordidity rates of patient treated for HCC was 30% and mortality was 4,3% for the entire study population. Five year overall survival rate was 39 % with statistically significant differences between transplanted, resected, or ablated patients (p 0.05) with better results in case of LT followed by LR and RFA. Conclusions: In HCC patients without liver cirrhosis, liver resection is the treatment of choice. For early HCC occurred on cirrhosis, LT offers the best outcome in terms of overall and disease free survival. RFA colud be a curative method for HCC patients not amenable for LT of LR. Celsius.

    To present safety and efficacy results obtained in treatment of a cohort of patients with unresectable hepatocellular carcinoma (HCC) with use of 90Y microspheres (TheraSphere). Forty-three consecutive patients with HCC were treated with 90Y microspheres over a 4-year period. Patients were treated by liver segment or lobe on one or more occasions based on tumor distribution, liver function, and vascular flow dynamics. Patients were followed for adverse events, objective tumor response, and survival. Patients were stratified into three risk groups according to method of treatment and risk stratification (group 0, segmental; group 1, lobar low-risk; group 2, lobar high-risk) and Okuda and Child-Pugh scoring systems. Based on follow-up data from 43 treated patients, 20 patients (47%) had an objective tumor response based on percent reduction in tumor size and 34 patients (79%) had a tumor response when percent reduction and/or tumor necrosis were used as a composite measure of tumor response. There was no statistical difference among the three risk groups with respect to tumor response. Survival times from date of diagnosis were different among the risk groups (P TheraSpheres) provides a safe and effective method of treatment for a broad spectrum of patients presenting with unresectable HCC. Further investigation is warranted.

    To present the clinical data of 35 patients with T3 unresectable hepatocellular carcinoma (HCC) that were treated with (90)Y with the specific intent of downstaging to resection, radiofrequency ablation (RFA) candidate, United Network for Organ Sharing (UNOS) stage T2 or liver transplantation. One hundred fifty patients with unresectable HCC were treated with (90)Y microspheres. Of these, 35 patients were UNOS stage T3 at the time of treatment. Patients were followed for clinical toxicities, alterations in model for end-stage-liver disease (MELD) score, tumor response, downstaging to RFA, resection, transplantation, and survival. Nineteen of 34 patients (56%) were successfully downstaged from T3 to T2 following treatment. 11 of 34 (32%) patients treated were downstaged to target lesions measuring 3.0 cm or less. Twenty-three of 35 (66%) were downstaged to either T2 status, lesion < 3.0 cm (RFA candidate), or resection. Seventeen of 34 (50%) had an objective tumor response by WHO criteria. Eight patients (23%) were successfully downstaged and underwent OLT following treatment. 1, 2, and 3-year survival was 84%, 54%, and 27%, respectively. Median survival by Kaplan-Meier analysis for the entire cohort was 800 days. These data suggest that intra-arterial (90)Y microspheres can be used as a bridge to transplantation, surgical resection, or RFA. (c) 2006 Wiley-Liss, Inc.

    2017-01-01

    Full Text Available Background. Sorafenib, an oral tyrosine kinase inhibitor (TKI, targets multiple tyrosine kinase receptors (TKRs involved in angiogenesis and tumor growth. Studies suggest that inhibition of TKR impacts cardiomyocyte survival. Inhibition of VEGF signaling interrupts angiogenesis and is associated with the development of hypertension and compensatory hypertrophy. Compensated hypertrophy ultimately leads to heart failure. Case Description. A 76-year-old man with a past medical history of systolic heart failure due to ischemic cardiomyopathy and stage IIIC hepatocellular carcinoma (HCC presented with symptoms of decompensated heart failure. Four months prior to admission, he was started on sorafenib. Results. Our patient was treated with intravenous furosemide and guideline directed therapy. Clinical status was complicated by the development of low cardiac output and shock requiring inotropic support. Careful titration of heart failure medication led to hemodynamic improvement and discontinuation of dobutamine. Conclusion. Greater awareness of sorafenib cardiotoxicity is essential. As TKI usage grows for treatment of cancers, heart failure-related complications will increase. In our patient, routine heart failure management and cessation of sorafenib led to clinical improvement. Future studies on the treatment of sorafenib cardiotoxicity should be explored further in this unique patient population.

    Some small hepatocellular carcinoma (HCC) lesions show as tumor stains by dynamic CT, but cannot be detected by ultrasonography. Percutaneous ethanol injection (PEI) is effective for treating small HCC lesions, but lack of adequate visualization of some lesions can limit its use. In this study, interventional radiographic, CT-fluoroscopically-guided PEI was performed as a new method for treating small HCC lesions that were difficult to detect by ultrasonography. Interventional radiographic, CT-fluoroscopically-guided PEI was performed on 11 patients (12 lesions) with HCC lesions measuring 2 cm or less in diameter. A thin needle was introduced into each tumor under CT-fluoroscopic guidance, with injection of contrast medium into the dominant hepatic artery. While lesions were observed using CT-fluoroscopy with the arteriogram, absolute ethanol was injected into the tumors. The ethanol injection rate and volume were monitored by observation of loss of tumor staining during real-time CT angiography. Needle introduction was successful in all 12 lesions, and disappearance of tumor staining was immediately observed on CT images after ethanol injection. Complications noted after treatment were local abdominal pain in all 11 patients, a slight fever in 9 patients, pneumothorax, right pleural effusion, and ascites, each in 1 patient. No other serious complications were observed. Interventional radiographic, CT-fluoroscopically-guided PEI is effective in the treatment of small HCC lesions, which are difficult to show by ultrasonography and treat by conventional PEI. (author)

    Objective: To investigate the side effects and curative effect in high-dosed lipiodol-transcatheter arterial chemoembolization as a treatment of large hepatocellular carcinoma. Methods: 79 patients with unresectable hepatocellular carcinoma were treated by TACE, and divided into 2 groups. In group A, 39 patients with the tumor sized 7-18cm in diameter, routine-dosed, 10-20ml lipiodol was given in TACE. 40 patients were enrolled in the high-dosed group B, who were given more than 20ml iodized oil in TACE. Results: The First to third year survival rate of group A was 66.7%, 33.3%, 0% respectively,while in group B it was 75%, 45%, 7.5% respectively. The effective rate was 71.7% in Group A and 87.5% in Group B. There was a significant difference between both groups. There was no significant difference of critical side effects and liver function damage between group A and B. Conclusion: High-dosed lipiodol chemoembolization as a treatment of unresectable hepatocellular carcinoma is superior to the routine TACE, especially when the tumor is large and the liver function reserve is good.

    We report on our experience in terms of eligibility, safety, response and survival for treatment of hepatocellular carcinoma (HCC) with 90 Y microspheres. Secondly, we investigated the urinary excretion of 90 Y following treatment. We retrospectively reviewed all HCC patients referred to our department for 90 Y microsphere treatment. We recorded reasons for not proceeding to actual treatment. In case treatment was performed, we assessed the tolerance (Common Terminology Criteria for Adverse Events v3.0, CTCAE v3.0), the response [modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria] and long-term survival (Kaplan-Meier). The urinary excretion was estimated by 12-h urine collections post-injection for analysis in a gamma counter. Forty-three HCC patients were referred for radioembolization. Fourteen patients were excluded, mainly due to unfavourable 99m Tc-macroaggregated albumin (MAA) distribution. Twenty-nine patients were treated with 90 Y microspheres (TheraSphere, mean activity 2.17 GBq). In four patients severe clinical adverse events were encountered, however only in one case clearly related to the therapy. Twenty patients were assessable by mRECIST: complete response in 15%, partial response in 35%, stable disease in 30% and progression in 20% were observed. A median survival of 12.3 months (95% confidence interval 9.4-15.2) was estimated. Concerning the substudy on urinary excretion, only 0.0025% of the administered activity was excreted in the urine within the first 12 h following TheraSphere. Following a strict workup before admitting patients to radioembolization with TheraSphere, we found good clinical tolerance in the vast majority of patients. Radiological response assessment yielded an overall response rate of 50%, when evaluated early following treatment. Urine analysis showed consistently only low activities of 90 Y excreted in the urine. (orig.)

    Objective: To evaluate the clinical efficacy of thermo-chemotherapy and thermo-lipiodol embolization in treatment of primary hepatocellular carcinoma(PHC). Methods: One hundred and sixteen cases of PHC were divided into three groups. Group A (38 cases)was treated with normal temperature chemotherapy and normal temperature lipiodol, Group B(40 cases)with thermo-chemotherapy and normal temperature lipiodol and group C (38 cases)with thermo-chemotherapy and thermo-lipiodol. Group B and group C were called the thermotherapy group. Results: In the thermotherapy groups, the rates of tumor size reduction were significantly greater than those in the normal group. There were no significant different in the hepatic function tests among the three groups. The 6-, 12-, 18-, and 24- month survival rates of the normal group and thermotherapy groups were 97%, 58%, 39% and 18%, versus 99%, 79%, 57% and 36%, respectively. No significant differences were found in the rates of reduction of tumor size and survival rates between group B and group C. Conclusion: Thermo-chemotherapy and thermo-embolization possess significant effect on PHC but without conspicuous damage to liver function. (authors)

This study aimed to evaluate the performance of {sup 18}F-fluorodeoxyglucose positron emission tomography ({sup 18}F-FDG PET) for predicting tumour progression during sorafenib treatment. We formed a retrospective cohort comprising patients treated with sorafenib for at least 30 days and undergoing {sup 18}F-FDG PET/CT within 1 month before treatment. For statistical analyses, the tumour-to-liver standardised uptake value (SUV) ratio (TLR) of the most hypermetabolic lesion was measured. Among a total of 35 patients, two obtained partial remission, and 11 showed stable disease after the first response evaluation. Patients with a TLR ≥ 2.9 (n = 17) had a median overall survival (OS) of 3.7 months after sorafenib treatment, whereas patients with a TLR < 2.9 (n = 18) had median OS of 12.2 months (P < 0.001), although the disease control rate was not significantly different between the two groups. Pretreatment TLR ≥ 2.9 (hazard ratio [HR] = 6.318, P = 0.002) and Child-Pugh class B (HR = 4.316, P = 0.044) were poor prognostic factors for OS, and a TLR ≥ 2.9 (HR = 2.911, P = 0.024) was the only poor prognostic factor for progression-free survival in a multivariate analysis. Pretreatment tumour metabolic activity assessed by {sup 18}F-FDG PET is an independent prognostic factor for survival in patients with BCLC-C stage HCC receiving sorafenib monotherapy, although it may not predict tumour response to the treatment.

    The overwhelming need to improve preclinical models in oncology has stimulated research efforts to refine and validate robust orthotopic models that closely mimic the disease population and therefore have the potential to better predict clinical outcome with novel therapies. Sophisticated technologies including bioluminescence, contrast enhanced ultrasound imaging, positron emission tomography, computed tomography and magnetic resonance imaging have been added to existing serum- and histology-based biomarkers to assist with patient selection and the design of clinical trials. The rationale for the use of human hepatocellular carcinoma (HCC) cell lines, implementation of xenograft and orthotopic animal models and utilization of available biomarkers have been discussed, providing guidelines to facilitate preclinical research for the development of treatments for HCC patients.

    The treatment of hepatocellular carcinoma (HCC) is complicated and challenging because of the frequent presence of cirrhosis. Therefore, we propose a novel surgical approach to minimize the invasiveness and risk in patients with HCC, hypersplenism, and esophagogastric varices. This was a retrospective study carried out in 25 patients with HCC and hypersplenism and who underwent simultaneous laparoscopic-guided radio-frequency ablation and laparoscopic splenectomy with endoscopic variceal ligation. Tumor size was restricted to a single nodule of splenectomy. Laparoscopic-guided radio-frequency ablation with laparoscopic splenectomy and endoscopic variceal ligation could be an available technique for patients with HCC <3 cm, hypersplenism, and esophagogastric varices. This approach may help to minimize the surgical risks and results in a fast increase in platelet counts with an acceptable rate of complications.

    To describe the clinico-pathological and radiological profile of hepatocellular carcinoma. All consecutive patients suspected of having hepatocellular carcinoma (HCC), were admitted and included in this study. Diagnosis of HCC was established by clinical, biochemical, ultrasonographic and histopathologic findings. Patients with primary carcinoma elsewhere in the body, metastatic in the liver, fibrolamellar carcinoma and benign tumours were excluded from the study. At ultrasonography, the details of tumour size and number, portal vein thrombosis and presence of ascites were recorded. Patients were staged according to Okuda staging system. Results were described in mean and percentage values. There were 82 patients with hepatocellular carcinoma including 58 males and 24 females, with male to female ratio of 2.8:1. The mean age of patients was 56.24 +- 13.65 years. Right hypochondrial pain was the main symptom in 52 (63.4%) patients. The duration of symptoms varied from 1 month to 2 years. Tumour size was larger than 50% of liver size in 42 (51.2%) with portal vein thrombosis in 10 (12.19%). Anti HCV was positive in 44 (53.7%), HBsAg in 26 (31.7%) and both were found positive in 2 (2.44%) patients. Ten patients (12.2/%) found negative both for anti-HCV and HBsAg. According to Okuda staging system 18 patients had stage 1, 50 had stage 2 and 14 had stage 3 hepatocellular carcinoma. The mean age of presentation of hepatocellular carcinoma was younger as compared to western countries with potentially large non-resectable lesions. Chronic hepatitis C and B was found to be the major known factors. Patients with chronic hepatitis C and B should undergo vigorous HCC surveillance to detect early, potentially respectable HCC.

    To compare treatment outcomes of subcentimeter hypervascular nodules at high risk for developing into hepatocellular carcinomas (SHNHR) between early treatment and watchful waiting until progression to overt hepatocellular carcinoma (HCC) groups. SHNHRs were defined as subcentimeter hypervascular nodules with the usual imaging features of HCC on gadoxetic acid-enhanced magnetic resonance imaging (MRI). Among 63 patients with 74 SHNHRs, 27 (37 SHNHRs) received early treatment (treatment of < 1 cm nodules), and 36 (37 SHNHRs) underwent watchful waiting until progression to overt HCC. Risk factor analysis was performed for recurrence-free and local recurrence-free survival. Among the 36 patients who adopted watchful waiting, 33 eventually underwent treatment because their SHNHRs progressed to overt HCC. For recurrence-free survival, significant risk factors included number of previous treatments (HR, 1.181; p < 0.001), tumour number (HR, 1.943; p = 0.009), and α-feto protein level (HR, 1.005; p = 0.037) in the multivariate analyses. Treatment strategy was not a significant risk factor for recurrence-free survival. For local recurrence-free survival from the date of treatment, only treatment modality (transarterial chemoembolization) (HR, 6.879; p = 0.002) was a significant risk factor. Recurrence-free survival was not significantly different between early treatment and watchful waiting for SHNHRs. (orig.)

    Risk of hepatocellular carcinoma (HCC) may be difficult to determine in the clinical setting. Develop a scoring system to forecast HCC risk among patients with chronic hepatitis C. Using data from the Chronic Hepatitis Cohort Study collected during 2005-2014, we derived HCC risk scores for males and females using an extended Cox model with aspartate aminotransferase-to-platelet ratio index (APRI) as a time-dependent variables and mean Kaplan-Meier survival functions from patient data at two study sites, and used data collected at two separate sites for external validation. For model calibration, we used the Greenwood-Nam-D'Agostino goodness-of-fit statistic to examine differences between predicted and observed risk. Of 12,469 patients (1628 with a history of sustained viral response [SVR]), 504 developed HCC; median follow-up was 6 years. Final predictors in the model included age, alcohol abuse, interferon-based treatment response, and APRI. Point values, ranging from -3 to 14 (males) and -3 to 12 (females), were established using hazard ratios of the predictors aligned with 1-, 3-, and 5-year Kaplan-Meier survival probabilities of HCC. Discriminatory capacity was high (c-index 0.82 males and 0.84 females) and external calibration demonstrated no differences between predicted and observed HCC risk for 1-, 3-, and 5-year forecasts among males (all p values >0.97) and for 3- and 5-year risk among females (all p values >0.87). This scoring system, based on age, alcohol abuse history, treatment response, and APRI, can be used to forecast up to a 5-year risk of HCC among hepatitis C patients before and after SVR.

    Radiofrequency hyperthermia using the newly-developed 'cooled-tip' needle has recently been proposed as a therapeutic modality for hepatocellular carcinoma (HCC). Herein we report our preliminary results on feasibility and effectiveness of the thermal ablation of mono- or pauci-focal hepatocellular carcinoma with the cooled-tip needle. We treated 15 cirrhotic patients (mean age 68.8 years; 12 males; 14 HCV-positive; 13 in Child's Class A and 2 in Class B) with 20 hepatocellular carcinoma nodules (mean diameter 28.1 mm; range 10-43 mm; nine lesions with diameter greater than 3 cm). None of the patients had portal thrombosis and/or extrahepatic spread. We used a radiofrequency generator (100 W of power) connected to a 18 g perfusion electrode needle with an exposed tip of 2-3 cm. The circuit was closed through a dispersive electrode positioned under the patient's thighs. A peristaltic pump infused a chilled (2-5 degrees C) saline solution to guarantee the continuous cooling of the needle tip. The needle was placed into target lesions under US guidance. The interventional procedure was carried out in general anesthesia without intubation. Dynamic helical CT was carried out 15-20 days after thermal ablation to assess therapeutic efficacy. In all, 38 areas of coagulation necrosis (at 1000-1200 mA for 10-15 min) were generated in 24 sessions in the 20 hepatocellular carcinoma nodules (mean 1.9 lesions per nodule and 1.2 sessions per nodule). Complete necrosis as assessed at dynamic CT (lack of enhancement during the arteriographic phase) was achieved in 75% of cases in a single session; after a second RF session success rate was 90% (18 out of 20 nodules). A self-limited pleurisy along with a 5-fold increase in transaminases occurred in one patient; a 3-fold elevation of transaminases was encountered in three other patients. During the follow-up (median 15 months) five patients had recurrent hepatocellular carcinoma with a 1-year disease free interval of 64%. Of the

    Background The delivery of treatment for hepatocellular carcinoma (HCC) could be influenced by place of HCC diagnosis (hospitalization vs. outpatient), subspecialty referral following diagnosis, as well as physician and facility factors. We conducted a study to examine the effect of patient and non-patient factors on the place of HCC diagnosis, referral, and treatment in Veterans Administration (VA) hospitals in the United States. Methods Using the VA Hepatitis C Clinical Case Registry, we identified HCV-infected patients who developed HCC during 1998–2006. All cases were verified and staged according to Barcelona Clinic Liver Cancer (BCLC) criteria. The main outcomes were place of HCC diagnosis, being seen by a surgeon or oncologist, and treatment. We examined factors related to these outcomes using hierarchical logistic regression. These factors included HCC stage, HCC surveillance, physician specialty, and facility factors, in addition to risk factors, co-morbidity, and liver disease indicators. Results Approximately 37.2% of the 1,296 patients with HCC were diagnosed during hospitalization, 31.0% were seen by a surgeon or oncologist, and 34.3% received treatment. Being seen by a surgeon or oncologist was associated with surveillance (adjusted odds ratio (aOR)=1.47;95%CI:1.20–1.80) and varied by geography (1.74;1.09–2.77). Seeing a surgeon or oncologist was predictive of treatment (aOR=1.43;95%CI:1.24–1.66). There was a significant increase in treatment among patients who received surveillance (aOR=1.37; 95%CI:1.02–1.71), were seen by gastroenterology (1.65;1.21–2.24) or were diagnosed at a transplant facility (1.48;1.15–1.90). Conclusions Approximately 40% of patients were diagnosed during hospitalization. Most patients were not seen by a surgeon or oncologist for treatment evaluation and only 34% received treatment. Only receipt of HCC surveillance was associated with increased likelihood of outpatient diagnosis, being seen by a surgeon or

    AIM: To investigate the anti-cancer effect and the immunological mechanism of ultrasound-guided intratumoral injection of Chinese medicine "Star-99" in hepatocellular carcinoma (HCC) of nude mice.METHODS: Twenty-eight human hepatocellular carcinoma SMMC-7721 transplanted nude mice, 14 of hypodermically implanted and 14 of orthotopic liver transplanted, were randomly divided into three groups of which 14 mice with Star-99, and 7 with ethanol and saline respectively. Ten days after the transplantation the medicines were injected into the tumors of all the nude mice once every 5 days.After 4 injections the nude mice were killed. The diameters of three dimension of the tumors were measured by high frequency ultrasound before and after the treatment and the tumor growth indexes* (TGI) were calculated.Radioimmunoassay was used to detect the serum levels of interleukin-2 (IL-2) and tumor necrosis factor (TNF)-alpha.The tumor tissues were sent for flow cytometry (FCM) DNA analysis. Apoptotic cells were visualized by TUNEL assay.All the experiments were carried out by double blind method. zRESULTS: The TGI of Star-99 group (0.076±0.024) was markedly lower than that of the saline group (4.654±1.283)(P<0.01). It also seemed to be lower than that of the ethanol group (0.082±0.028), but not significantly different (P>0.05).Serum levels of IL-2 and TNF-α were markedly higher than those of ethanol group and saline groups (P<0.05). The mean apoptotic index (AI: percentage of TUNEL signal positive cells)in Star-99 group (48.98±5.09 %) was significantly higher than that of the ethanol group (11.95±2.24 %) and the saline group (10.48±3.85 %) (P<0.01). FCM DNA analysis showed that the appearance rate of the apoptosis peak in Srar-99group was 92.9 %, markedly higher than that of the ethanol group (14.3 %) and the saline group (0.0 %) (P<0.01).Correlation (r=0.499, P<0.05) was found between AI and serum level of TNF-α.CONCLUSION: Star-99 has an effect on the

    To determine the optimal pulse sequence for detection and differential diagnosis of small hepatocellular carcinomas and cavernous hemangiomas less than 5 cm in diameter, the authors have analyzed spin-echo (SE) images of 15 small hepatocellular carcinomas and 31 small cavernous hemangiomas obtained at 2.0 T. Pulse sequences used included repetition times (TRs) of 500 and 2,000 msec and echo times (TEs) of 30,60,90,120,150, and 180 msec. Mean tumor-liver contrast-to-noise ratios on the SE 2,000/60 (TR msec/TE msec) sequence were 23.90 ± 16.33 and 62.10 ± 25.94 for small hepatocellular carcinomas and hemangiomas, respectively, and were significantly greater than for all other pulse sequences. Mean tumor-liver signal intensity ratios on the SE 2,000/150 sequence were 2.34 ± 1.72 and 6.04 ± 2.72 for small hepatocellular carcinomas and hemangiomas, respectively, and were significantly greater than for all other pulse sequences in hemangiomas

    Objective: It has long been known that high intensity focused ultrasound (HIFU) can kill tissue through coagulative necrosis. However, it is only in recent years that practical clinical applications are becoming possible. Since the ribs have strong reflections to ultrasonic beams, they may affect the deposition of ultrasound energy, decreasing the efficacy of HIFU treatment and increasing the chance of adverse events when the intra-abdominal tumours concealed by ribs are treated. The aim of this study was to evaluate the influence of partial rib resection on the efficacy and safety of HIFU treatment. Methods: This prospective study was approved by the ethics committee at Chongqing University of Medical Sciences. An informed consent form was obtained from each patient and family member. A total of 16 patients with hepatocellular carcinoma (HCC), consisting of 13 males and 3 females, were studied. All patients had the successful HIFU treatment. To create a better acoustic pathway for HIFU treatment, all of the 16 patients had the ribs that shield the tumour mass to be removed. Magnetic resonance imaging (MRI) was used to evaluate the efficacy of HIFU treatment. Results: Sixteen cases had 23 nodules, including 12 cases with a single nodule, 1 case with 2 nodules, 3 cases with 3 nodules. The mean diameter of tumours was 7.0 ± 2.1 cm (5-10 cm). According to TNM classification, 9 patients were diagnosed as stage II, 4 patients were stage III, and 3 patients were stage IV. Follow-up imaging showed an absence of tumour blood supply and shrinkage of all treated lesions. The survival rates at 1, 2, 3, 4, and 5 years were 100%, 83.3%, 69.4%, 55.6%, and 55.6%, respectively. No serious complications were observed in the patients treated with HIFU. Conclusion: Partial rib resection can create a better acoustic pathway of HIFU therapy. Even though it is an invasive treatment, this measure offers patients an improved prospect of complete tumour ablation when no other treatment is

    Hepatocellular carcinoma (HCC) is the most common primary liver cancer and has very limited therapeutic options. Recently, it has been found that hyaluronic acid (HA) shows selective binding to CD44 receptors expressed in most cancer histotypes. Since the trend in cancer treatment is the use of targeted radionuclide therapy, the aim of this research was to label HA with rhenium-188 and to evaluate its potential use as a hepatocarcinoma therapeutic radiopharmaceutical. Methods: 188 Re-HA was prepared by a direct labelling method to produce a ReO(O-COO) 2 -type coordination complex. 188 Re-HA protein binding and its stability in saline, phosphate buffer, human serum and cysteine solutions were determined. Biokinetic and dosimetric data were estimated in healthy mice (n=60) using the Medical Internal Radiation Dose methodology and mouse model beta-absorbed fractions. To evaluate liver toxicity, alanine aminotranferase (AST) and aspartate aminotranferase (ALT) levels in mice were assessed and the liver maximum tolerated dose (MTD) of 188 Re-HA was determined. Results: A stable complex of 188 Re-HA was obtained with high radiochemical purity (>90%) and low serum protein binding (2%). Biokinetic studies showed a rapid blood clearance (T 1/2 α=21 min). Four hours after administration, 188 Re-HA was almost totally removed from the blood by the liver due to the selective uptake via HA-specific receptors (73.47±5.11% of the injected dose). The liver MTD in mice was ∼40 Gy after 7.4 MBq of 188 Re-HA injection. Conclusions: 188 Re-HA complex showed good stability, pharmacokinetic and dosimetric characteristics that confirm its potential as a new agent for HCC radiation therapy.

    Aim: To assess clinical outcome of transarterial chemoembolization (TACE) in a series of patients with early-stage hepatocellular carcinoma (HCC), within Milan criteria, but clinically unfit for liver transplantation (OLT). Methods: From January 2006 to May 2009, 67 patients (43 males, mean age 70 ± 7.6 years) with very early or early-stage unresectable HCC, within Milan selection criteria but clinically unfit for OLT, underwent TACE. The primary endpoint of the study was overall survival. Secondary endpoints were: safety, liver toxicity, 1-month tumour response according to the amended RECIST criteria, time to local and distant intrahepatic tumour recurrence and time to radiological progression. Results: Two major periprocedural complications occurred (3%), consisting of liver failure. Periprocedural mortality rate was 1.5% (1 patient). A significant increase in ALT and bilirubin levels 24 h after treatment was reported, with progressive decrease at discharge. At 1-month follow-up, complete and partial tumour response rates were 67.2% and 29.8%, respectively, with two cases of progressive disease. Mean follow-up was 37.3 ± 15 months. The 1-, 2-, and 3-year overall survival rates were 90.9%, 86.1%, and 80.5%, respectively. Median expected time to local tumour recurrence and intrahepatic tumour recurrence were 7.9 and 13.8 months, respectively. Radiological disease progression was observed in 12 patients (17.9%) with a mean expected time of 26.5 months. Conclusion: In patients with early-stage HCC, clinically excluded from OLT and unfit for surgery or percutaneous ablation, TACE is a safe and effective option, with favourable long-term survival.

    Everolimus is an orally administrated mammalian target of rapamycin (mTOR) inhibitor. Several large-scale randomized controlled trials (RCTs) have demonstrated the survival benefits of everolimus at the dose of 10 mg/day for solid cancers. Furthermore, mTOR-inhibitor-based immunosuppression is associated with survival benefits for patients with hepatocellular carcinoma (HCC) who have received liver transplantation. However, a low rate of tumor reduction and some adverse events have been pointed out. This review summarizes the antitumor effects and adverse events of everolimus and evaluates its possible application in advanced HCC. For the meta-analysis of adverse events, we used the RCTs for solid cancers. The odds ratios of adverse events were calculated using the Peto method. Manypreclinical studies demonstrated that everolimus had antitumor effects such as antiproliferation and antiangiogenesis. However, some differences in the effects were observed among in vivo animal studies for HCC treatment. Meanwhile, clinical studies demonstrated that the response rate of single-agent everolimus was low, though survival benefits could be expected. The meta-analysis revealed the odds ratios (95% confidence interval [CI]) of stomatitis: 5.42 [4.31–6.73], hyperglycemia: 3.22 [2.37–4.39], anemia: 3.34 [2.37–4.67], pneumonitis: 6.02 [3.95–9.16], aspartate aminotransferase levels: 2.22 [1.37–3.62], and serum alanine aminotransferase levels: 2.94 [1.72–5.02], respectively. Everolimus at the dose of 10 mg/day significantly increased the risk of the adverse events. In order to enable its application to the standard conventional therapies of HCC, further studies are required to enhance the antitumor effects and manage the adverse events of everolimus

    Hepatocellular carcinoma (HCC) is the most common primary liver cancer and has very limited therapeutic options. Recently, it has been found that hyaluronic acid (HA) shows selective binding to CD44 receptors expressed in most cancer histotypes. Since the trend in cancer treatment is the use of targeted radionuclide therapy, the aim of this research was to label HA with rhenium-188 and to evaluate its potential use as a hepatocarcinoma therapeutic radiopharmaceutical. Methods: {sup 188}Re-HA was prepared by a direct labelling method to produce a ReO(O-COO){sub 2}-type coordination complex. {sup 188}Re-HA protein binding and its stability in saline, phosphate buffer, human serum and cysteine solutions were determined. Biokinetic and dosimetric data were estimated in healthy mice (n=60) using the Medical Internal Radiation Dose methodology and mouse model beta-absorbed fractions. To evaluate liver toxicity, alanine aminotranferase (AST) and aspartate aminotranferase (ALT) levels in mice were assessed and the liver maximum tolerated dose (MTD) of {sup 188}Re-HA was determined. Results: A stable complex of {sup 188}Re-HA was obtained with high radiochemical purity (>90%) and low serum protein binding (2%). Biokinetic studies showed a rapid blood clearance (T{sub 1/2}{alpha}=21 min). Four hours after administration, {sup 188}Re-HA was almost totally removed from the blood by the liver due to the selective uptake via HA-specific receptors (73.47{+-}5.11% of the injected dose). The liver MTD in mice was {approx}40 Gy after 7.4 MBq of {sup 188}Re-HA injection. Conclusions: {sup 188}Re-HA complex showed good stability, pharmacokinetic and dosimetric characteristics that confirm its potential as a new agent for HCC radiation therapy.

    Preoperative prediction of both microinvasive hepatocellular carcinoma and histological grade of hepatocellular carcinoma is pivotal to treatment planning and prognostication. The aim of this study was to evaluate whether some intraoperative ultrasound features correlate with both the presence of same histological patterns and differentiation grade of hepatocellular carcinoma on the histological features of the primary resected tumour. All patients with single, small hepatocellular carcinoma that underwent hepatic resection were included in this prospective double-blind study: the intraoperative ultrasound patterns of nodule were registered and compared with similar histological features. A total of 179 patients were enclosed in this study: 97 (54%) patients (34% in HCC ≤2 cm) had a microinvasive hepatocellular carcinoma at ultrasound examination, while 82 (46%) patients (41% in HCC ≤2 cm) at histological evaluation. Statistical analysis showed that diameters ≤2 cm, presence of satellites and microinvasive hepatocellular carcinoma at ultrasound examination were the variables with the strongest association with the histological findings. In the multivariate analysis, the vascular microinfiltration and infiltrative hepatocellular carcinoma aspect were independent predictors for grading. In patients with cirrhosis and hepatocellular carcinoma, the prevalence of microinvasive hepatocellular carcinoma is high, even in cases of HCC ≤2 cm. Intraoperative ultrasound findings strongly correlated with histopathological criteria in detecting microinvasive patterns and are useful to predict neoplastic differentiation. The knowledge of these features prior to treatment are highly desired (this can be obtained by an intraoperative ultrasound examination), as they could help in providing optimal management of patients with hepatocellular carcinoma. © 2017 John Wiley & Sons A/S.

    Underlying liver cirrhosis is present in most patients with hepatocellular carcinoma, and liver transplantation is the only treatment strategy to cure both diseases. All other hepatocellular carcinoma treatment strategies have to take into account residual liver function that concurs with the patient's prognosis and might limit their feasibility. In patients with hepatocellular carcinoma and Child-Pugh-Turcotte class B (CPT-B), owing to borderline liver function, any intervention might be offset by liver function deterioration. In this setting, the decision for hepatocellular carcinoma treatment requires a comprehensive assessment of liver function, not restricted to the CPT classification, in addition to a careful evaluation of the prognostic effect of hepatocellular carcinoma compared with cirrhosis. In this Review, we provide an overview of the literature regarding the benefits and harms of non-transplant therapies in patients with hepatocellular carcinoma and CPT-B cirrhosis.

    The purposes of this study were to evaluate the biodistribution and effect of Ho-166 radionuclide by intra-arterial injection of the Ho-166 chitosan complex in dogs and to assess the clinical efficacy and side effects of this complex in the treatment of hepatocellular carcinoma (HCC). In an experimental study, 20 mCi of Ho-166 chitosan complex was injected into the left hepatic artery of six adult dogs. The distribution of radioactivity in each organ was calculated using a gamma camera scan at regular intervals. A beta ray radioactivity count (cpm) of blood and urine was performed periodically, and hematologic and hepatic function were regularly assessed. At 4, 8 and 12 weeks after intra-arterial injection, bone marrow and liver were pathologically evaluated. Twenty-five patients with a single, nodular HCC mass 3-9 cm in diameter were treated by intra-arterial injection of Ho-166 chitosan complex, and immediately after the procedure a gamma camera scan was obtained. A beta ray radioactivity count(CPM) of blood was performed periodically, hematologic and hepatic function were regularly evaluated, and CT scans and angiograms were obtained 3 months after the procedure. On the basis of the CT and angiographic findings, the treatment effects were classified as complete (CR), partial (PR) or non-response(NR). In the animal study, blood radioactivity peaked immediately in each organ per whole body was 25% in the left lobe of the liver, 7% in the right lobe, 3% in the lung, 1.4-3% in the bladder, and 2% in bone. WBC and platelet counts declined maximally at 3-4 weeks and recovered at 12 weeks the cellularity of bone marrow was 25% at 4 weeks and 55% at 12 weeks, findings which correlated well with the observed hematologic changes. In the clinical study of 25 HCC patients, CR was achieved in 17 (68%) cases, PR in 5 (20%) and NR in 3 (12%). At gamma camera imaging immediately after treatment, tumor radioactivity was localized in 76% of cases. In six cases (24%) WBC and

    Hepatocellular carcinoma (HCC), the predominant form of primary liver cancer, is the fifth most common cancer worldwide and the second leading cause of cancer-related death. Despite the high incidence, treatment options remain limited for advanced HCC, and as a result prognosis continues to be poor. Current therapeutic options, surgery, chemotherapy and radiotherapy, have only modest efficacy. New treatment modalities to prolong survival and to minimize the risk of adverse response are desperately needed for patients with advanced HCC. Tumor immunotherapy is a promising, novel treatment strategy that may lead to improvements in both treatment-associated toxicity and outcome. The strategies have developed in part through genomic studies that have yielded candidate target molecules and in part through basic biology studies that have defined the pathways and cell types regulating immune response. Here, we summarize the various types of HCC immunotherapy and argue that the newfound field of HCC immunotherapy might provide critical advantages in the effort to improve prognosis of patients with advanced HCC. Already several immunotherapies, such as tumor-associated antigen therapy, immune checkpoint inhibitors and cell transfer immunotherapy, have demonstrated safety and feasibility in HCC patients. Unfortunately, immunotherapy currently has low efficacy in advanced stage HCC patients; overcoming this challenge will place immunotherapy at the forefront of HCC treatment, possibly in the near future.

    The incidence of hepatocellular carcinoma (HCC), once thought to be a rare tumor in North America, has rapidly increased in recent years in the United States. Current treatment modalities to halt the progression of this disease are only marginally effective. The mainstay treatment is liver transplantation, which is often confronted with donor shortage. Invasion, metastasis and recurrence contribute to the high mortality rate of this disease. Matrix metalloproteinases (MMPs) that degrade the e...

    Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death, and its increasing incidence worldwide is a cause for concern. Fortunately, advances in diagnostic and therapeutic approaches have contributed to earlier detection and treatment. As cancer epidemiology studies continue to elucidate the natural history of liver diseases, greater understanding of HCC has led to improved risk stratification and earlier enrollment of high-risk patients in cancer screening and surveillance programs. Improved survival rates among HCC patients also reflect significant advances in available treatment options. Advances in surgical techniques are pushing the boundaries of resection for localized disease, and progress in the field of transplantation has led to refinements in listing criteria and improved post-transplantation outcomes. The evolving field of locoregional therapies—including percutaneous ablation and transarterial chemoembolization—continues to provide novel therapeutic options that can be used in place of, or in addition to, surgical approaches. Recent advances in systemic multikinase inhibitor therapies have also demonstrated significant benefits for advanced-stage disease, and these therapies also show promise as adjuvant treatments for earlier-stage disease. This article provides an update on the management of HCC, with a focus on revised guidelines for screening and an in-depth discussion of emerging novel therapies. PMID:21346848

    To compare the safety profiles of TheraSphere ® (glass) and SIR-Spheres ® (resin) Y90 microspheres for the treatment of hepatocellular carcinoma. A systematic review was conducted using the databases MEDLINE, Embase, and Cochrane Trials Register to identify all relevant studies. Baseline characteristics and adverse events of all grades related to gastrointestinal, hepatobiliary, and respiratory systems were collected along with commonly reported outcomes related to post-embolization syndrome. For all outcomes, data from each study were tabulated for each intervention. Adverse events and patients were summed across studies on TheraSphere ® and SIR-Spheres ® , respectively, and the resulting proportion of patients experiencing an outcome for both interventions was calculated. Thirty-one observational studies were included in the review. In the adverse events of all grades, more patients treated with resin microspheres reported gastric ulcers, hepatic encephalopathy, cholecystitis, hepatic failure, and pleural effusion. Patients treated with resin microspheres also had more hepatobiliary adverse events of grade 3 or higher. In the events related to post-embolization syndrome, glass microspheres exhibited a similar safety profile compared to resin microspheres. Ascites and nausea grade 3 or higher were recorded more frequently with glass microsphere treatment. Based on this review of the published literature, glass microspheres exhibit a safety profile with fewer gastrointestinal and pulmonary adverse events compared to resin microspheres in the treatment of hepatocellular carcinoma.

    Full Text Available Abstract Background Liver disease is the second cause of death among HIV patients receiving highly active antiretroviral therapy (HAART in Europe. HIV patients have a high prevalence of chronic HBV (6–10% and HCV (33% co-infection, and accelerated progression of viral hepatitis. Furthermore, the long duration of both HIV and HCV diseases in the HAART era increases the risk of hepatocellular carcinoma. Findings We report the case of a 49 year -old HIV/HCV co-infected male patient who developed hepatocellular carcinoma. The patient underwent a partial hepatectomy, and a few months later was treated with transcatheter arterial chemoembolisation due to hepatocarcinoma recurrence. Two months later, advanced hepatocellular carcinoma was diagnosed and sorafenib therapy was initiated. The patient achieved partial response of the main lesions, complete regression of the smallest lesions and did not experience clinical progression during the 20-month follow-up period. During therapy with sorafenib, the patient was treated with HAART with good viral and immunological responses. We used the therapeutic drug monitoring to assess antiretroviral concentrations during co-administration of sorafenib. Fosamprenavir Ctrough was found under the minimum level recommended by international guidelines. No grade 3 or 4 toxicities were observed. At month 20 of treatment, new liver lesions with portal vein thrombosis were diagnosed. After 28 months of sorafenib therapy, the patient deceased for severe liver insufficiency. Conclusions Sorafenib monotherapy demonstrated a marked delay in HCC disease progression in an HIV/HCV co-infected patient. Fosamprenavir Ctrough was found under the minimum level recommended by international guidelines, suggesting a possible interaction.

    Orbital metastasis of hepatocellular carcinoma is exceedingly rare and caries a grave prognosis. Three cases of metastatic orbital hepatocellular carcinoma in which the primary tumor was initially unknown and the diagnostic challenges encountered are presented. With hepatocellular carcinoma, open biopsy and palliative tumor debulking has an increased bleeding risk due to the highly vascular nature of the tumor and coagulopathy associated with chronic liver disease. As an alternative, fine needle aspiration biopsy should be considered for hepatocellular carcinoma with a readily accessible mass and the availability of an experienced cytopathologist.

    Hepatocellular carcinoma is now a major public health concern. In intermediate stages (one third of hepatocellular carcinoma patients), chemo-embolization is the standard of care despite a poor tolerance and a moderate efficacy. Moreover, despite recent improvements, this technique seems in a dead end. Radio-embolization could be an excellent tool for such patients. Currently 131 I-Lipiodol, 188 Re-Lipiodol, 90 Y-glass or resin microspheres are available. More recent and promising data come from microspheres, but phase II and III studies are needed before drawing any conclusion. In the future, the combination of radio-embolization with systemic chemotherapy or targeted agents (particularly anti-angiogenic drugs) seems very promising. (authors)

    Full Text Available Background/Aims The diagnosis and treatment plan for hepatocellular carcinoma (HCC can be made from radiologic imaging. However, lesion detection may vary depending on the imaging modality. This study aims to evaluate the sensitivities of hepatic multidetector computed tomography (MDCT, magnetic resonance imaging (MRI, and digital subtraction angiography (DSA in the detection of HCC and the consequent management impact on potential liver transplant patients. Methods One hundred and sixteen HCC lesions were analyzed in 41 patients who received an orthotopic liver transplant (OLT. All of the patients underwent pretransplantation hepatic DSA, MDCT, and/or MRI. The imaging results were independently reviewed retrospectively in a blinded fashion by two interventional and two abdominal radiologists. The liver explant pathology was used as the gold standard for assessing each imaging modality. Results The sensitivity for overall HCC detection was higher for cross-sectional imaging using MRI (51.5%, 95% confidence interval [CI]=36.2-58.4% and MDCT (49.8%, 95% CI=43.7-55.9% than for DSA (41.7%, 95% CI=36.2-47.3% (P=0.05. The difference in false-positive rate was not statistically significant between MRI (22%, MDCT (29%, and DSA (29% (P=0.67. The sensitivity was significantly higher for detecting right lobe lesions than left lobe lesions for all modalities (MRI: 56.1% vs. 43.1%, MDCT: 55.0% vs. 42.0%, and DSA: 46.9% vs. 33.9%; all P<0.01. The sensitivities of the three imaging modalities were also higher for lesions ≥2 cm vs. <2 cm (MRI: 73.4% vs. 32.7%, MDCT: 66.9% vs. 33.8%, and DSA: 62.2% vs. 24.1%; all P<0.01. The interobserver correlation was rated as very good to excellent. Conclusion The sensitivity for detecting HCC is higher for MRI and MDCT than for DSA, and so cross-sectional imaging modalities should be used to evaluate OLT candidacy.

    Purpose To assess the long-term outcome in 108 consecutive patients treated with no-touch multibipolar radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) that met the Milan criteria. Materials and Methods This retrospective study was approved by the ethical review board, and the need to obtain informed consent was waived. Between November 1, 2006, and December 31, 2011, 132 HCC tumors (diameter, 10-45 mm; 39 tumors ≥ 30 mm) in 108 consecutive patients (106 with cirrhosis) that met Milan criteria were treated with no-touch multibipolar RFA, which consisted of activating, in bipolar mode, three or four electrodes inserted just beyond the tumor margins. Follow-up was performed every 3 months for 2 years and every 6 months thereafter with computed tomographic or magnetic resonance imaging. Survival probabilities were computed by using the Kaplan-Meier method. Predictive factors of tumor progression and overall survival were assessed by using the Cox proportional hazard model. Results No technical failure occurred, and complete ablation was achieved for all the nodules. After a median of 40.5 months (range, 2-84 months) of follow-up, 3- and 5-year local and overall tumor progression-free survival were 96%, 94%, 52%, and 32%, respectively. Neither tumor diameter greater than 30 mm nor location abutting a large vessel were associated with local tumor progression. Tumor diameter greater than 30 mm was the only parameter predictive of overall tumor progression (P = .0036). Independent factors associated with shorter overall survival were Child-Pugh class B disease, age greater than 65 years, and platelet count of less than 150 g/L (P touch multibipolar RFA for HCC tumors that meet Milan criteria provides a high local tumor progression-free survival rate. An ongoing randomized trial might help to clarify the role of this new approach for the treatment of early HCC. (©) RSNA, 2016 Online supplemental material is available for this article. An earlier

    Radiofrequency ablation is the recommended treatment for patients with hepatocellular carcinoma who have lesions smaller than 3 cm and are therefore not candidates for surgery. Microwave ablation is a more recent technique with certain theoretical advantages that have not yet been confirmed clinically. We aimed to compare the efficacy of both techniques in the treatment of hepatocellular carcinoma lesions of 4 cm or smaller. We did a randomised controlled, single-blinded phase 2 trial at four tertiary university centres in France and Switzerland. Patients with chronic liver disease and hepatocellular carcinoma with up to three lesions of 4 cm or smaller who were not eligible for surgery were randomised to receive microwave ablation (experimental group) or radiofrequency ablation (control group). Randomisation was centralised and done by use of a fixed block method (block size 4). Patients were randomly assigned by a co-investigator by use of the sealed opaque envelope method and were masked to the treatment; physicians were not masked to treatment, since the devices used were different. The primary outcome was the proportion of lesions with local tumour progression at 2 years of follow-up. Local tumour progression was defined as the appearance of a new nodule with features typical of hepatocellular carcinoma in the edge of the ablation zone. All analyses were done in the per-protocol population. The study is completed, but patients will continue to be followed up for 5 years. This study is registered with ClinicalTrials.gov, number NCT02859753. Between Nov 15, 2011, and Feb 27, 2015, 152 patients were randomly assigned: 76 patients to receive microwave ablation and 76 patients to receive radiofrequency ablation. For the per-protocol analysis, five patients were excluded from the microwave ablation group as were three patients from the radiofrequency ablation group. Median follow-up was 26 months (IQR 18-29) in the microwave ablation group and 25 months (18-34) in

    Having found raised serum calcitonin concentrations in 94% of patients with hepatocellular carcinoma when using a dextran-coated-charcoal radio-immunoassay, we have now repeated the study, using a double-antibody radio-immunoassay, in 102 further patients with hepatocellular carcinoma and 35 matched controls. Serum immunoreactive calcitonin concentrations (iCT) in the controls ranged from 10 to 310 pg/ml (mean 154,6 pg/ml). Values in the tumour patients ranged from 10 to 1,650 pg/ml (mean 302,6 pg/ml). The mean figures were significantly higher in the tumour patients (P smaller than 0,001), 35.5% of them having values above 310 pg/ml. In 65 of the patients serum iCT concentrations were also determined by dextran-coated-charcoal radio-immunoassay. Values ranged from 10 to 10780 pg/ml (mean 2,179 pg/ml). If 1,000 pg/ml is taken as the upper limit of normal, 69% of the patients had raised iCT concentrations. There was a good correlation (r=0,67; P smaller than 0,001) between serum iCT values measured with both methods in 50 patients. If measured by the double-antibody radio-immunoassay method, the serum calcitonin value is not useful as a marker for hepatocellular carcinoma.

    Thermo-ablation by radiofrequency is recognized as a curative treatment for early-stage hepatocellular carcinoma. However, local recurrence may occur because of incomplete peripheral tumor destruction. Multipolar radiofrequency has been developed to increase the size of the maximal ablation zone. We aimed to compare the efficacy of monopolar and multipolar radiofrequency for the treatment of hepatocellular carcinoma and determine factors predicting failure. A total of 171 consecutive patients with 214 hepatocellular carcinomas were retrospectively included. One hundred fifty-eight tumors were treated with an expandable monopolar electrode and 56 with a multipolar technique using several linear bipolar electrodes. Imaging studies at 6 weeks after treatment, then every 3 months, assessed local effectiveness. Radiofrequency failure was defined as persistent residual tumor after two sessions (primary radiofrequency failure) or local tumor recurrence during follow-up. This study received institutional review board approval (number 2014/77). Imaging showed complete tumor ablation in 207 of 214 lesions after the first session of radiofrequency. After a second session, only two cases of residual viable tumor were observed. During follow-up, there were 46 local tumor recurrences. Thus, radiofrequency failure occurred in 48/214 (22.4%) cases. By multivariate analysis, technique (P radiofrequency failure. Failure rate was lower with the multipolar technique for tumors radiofrequency, multipolar radiofrequency improves tumor ablation with a subsequent lower rate of local tumor recurrence. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    The radioconjugate was prepared by using an HDD (4-hexadecyl 1-2,9,9-tetramethyl-4,7-diaza-1,10-decanethiol) kit, and lipiodol. Over a period of 18 months, 70 patients received at least one treatment of radioconjugate. Some patients were re-treated if there was no evidence of disease progression. The level of radioconjugate administered was based on radiation-absorbed dose to critical normal organs, calculated following a ''scout'' dose of radioconjugate. The organs at greatest risk for radiation toxicity are the normal liver, the lung and the bone marrow. An Excel spreadsheet was used to determine maximum tolerated activity (MTA), defined as the amount of radioactivity calculated to deliver no more than 12 Gy to lungs, or 30 Gy to liver, or 1.5 Gy to bone marrow. Patients were followed for at least 12 weeks after therapy, until recovery from all toxicity. The clinical parameters evaluated included toxicity, response as determined by contrast-enhanced CT, palliation of symptoms, overall survival, performance status (Karnofsky) and hepatic function (Child's classification). Liver function tests, serum {alpha}-fetoprotein (AFP) levels and complete blood counts were done at each follow-up visit. In the majority of patients, the scout dose studies indicated the radiation absorbed dose to normalliver to be the limiting factor to the treatment dose, while in a few patients dose to lung was the limiting factor. Radiation dose to bone marrow was negligible and was thus not a factor for the MTA calculations. Side-effects were minimal and usually presented as loss of appetite, right hypochondrial discomfort and low-grade fever, even at high levels of administered radioactivity. The symptoms resolved with simple supportive therapy within 3 days of onset. Liver function tests at 24 and 72 h showed no significant changes and complete blood counts at 1 week, 4 weeks and 12 weeks showed no changes (no bone marrow suppression). Sixteen patients were

    To assess the arterial supply to hepatocellular carcinomas (HCCs) by inferior phrenic arteries (IPA). A total of 126 consecutive cases of HCC were studied by contract-enhanced CT and conventional arteriography. Blood supply from an IPA was suspected when the size of the HCC mass as seen on contrast-enhanced CT did not match the size of the tumor mass as seen on hepatic arteriography. Inferior phrenic arteriography was employed to confirm these findings. HCCs fed by the IPA were analyzed in terms of size, location, and history of prior treatment. In 14 (11%) of the 126 cases, the tumor was found to have a blood supply from an IPA. Eleven of these tumors were located in segments 2 and 7. Three tumors, which had not been treated previously, had a blood supply from an IPA. Six tumors were almost exclusively fed by an IPA and were located in segments 1, 1, and 4. HCCs located in segments which form the bare area of the liver (S1, S2, S7) can be supplied by an IPA. This should be suspected when a lesion or part of a lesion is identified on contrast-enhanced CT but not on hepatic arteriography.

    Hepatocellular carcinoma (HCC) is an increasing health problem, representing the second cause of cancer-related mortality worldwide. The major risk factor for HCC is cirrhosis. In developing countries, viral hepatitis represent the major risk factor, whereas in developed countries, the epidemic of obesity, diabetes and nonalcoholic steatohepatitis contribute to the observed increase in HCC incidence. Cirrhotic patients are recommended to undergo HCC surveillance by abdominal ultrasounds at 6-mo intervals. The current diagnostic algorithms for HCC rely on typical radiological hallmarks in dynamic contrast-enhanced imaging, while the use of α-fetoprotein as an independent tool for HCC surveillance is not recommended by current guidelines due to its low sensitivity and specificity. Early diagnosis is crucial for curative treatments. Surgical resection, radiofrequency ablation and liver transplantation are considered the cornerstones of curative therapy, while for patients with more advanced HCC recommended options include sorafenib and trans-arterial chemo-embolization. A multidisciplinary team, consisting of hepatologists, surgeons, radiologists, oncologists and pathologists, is fundamental for a correct management. In this paper, we review the diagnostic and therapeutic management of HCC, with a focus on the most recent evidences and recommendations from guidelines. PMID:26576088

    Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide. Although recent advances in therapeutic approaches for treating HCC have improved the prognoses of patients with HCC, this cancer is still associated with a poor survival rate mainly due to late diagnosis. Therefore, a diagnosis must be made sufficiently early to perform curative and effective treatments. There is a need for a deeper understanding of the molecular mechanisms underlying the initiation and progression of HCC because these mechanisms are critical for making early diagnoses and developing novel therapeutic strategies. Over the past decade, much progress has been made in elucidating the molecular mechanisms underlying hepatocarcinogenesis. In particular, recent advances in next-generation sequencing technologies have revealed numerous genetic alterations, including recurrently mutated genes and dysregulated signaling pathways in HCC. A better understanding of the genetic alterations in HCC could contribute to identifying potential driver mutations and discovering novel therapeutic targets in the future. In this article, we summarize the current advances in research on the genetic alterations, including genomic instability, single-nucleotide polymorphisms, somatic mutations and deregulated signaling pathways, implicated in the initiation and progression of HCC. We also attempt to elucidate some of the genetic mechanisms that contribute to making early diagnoses of and developing molecularly targeted therapies for HCC. PMID:27895396

    Full Text Available As the etiology of hepatocellular carcinoma (HCC has been changing, the incidence of HCC related to nonalcoholic fatty liver disease (NAFLD is gradually increasing in developed countries in Europe and America and some countries in Asia. This article introduces the close association between NAFLD and HCC, risk factors, clinicopathological features, and prevention and screening, and points out that although the incidence of NAFLD is not as high as that of hepatitis B- or hepatitis C-related HCC, there are a large absolute number of NAFLD patients, especially the high-risk patients with diabetes and obesity, or liver fibrosis/cirrhosis, due to a huge base number of NAFLD patients. NAFLD-related HCC is commonly seen in the elderly with various comorbidities and a poor prognosis. This article also points out that the prevention should focus on the effective treatment of NAFLD. The strict screening of high-risk population is the strategy for the diagnosis of early-stage HCC. At present, the sensitivity of alpha-fetoprotein is relatively low, and imaging examinations including computed tomography are the main screening methods; however, there are no measures for early warning of NAFLD-related HCC.

    A 14-year-old neutered male Bearded Collie was presented with a history of recurrent, intermittent urinary incontinence of 7 years duration. A large, firm, non-painful mass was found in the mid-abdominal region on palpation. Ultrasonography of the mass revealed a compartmentalised structure with mixed echogenicity, and which did not appear to be associated with any of the abdominal organs. Ultrasound-guided fine needle aspirates contained several clusters of epithelial cells with cytological features of hepatocytes. At exploratory laparotomy, the mass was found in the gastrosplenic ligament within the greater omentum. PATHOLOGICAL FINDINGS AND DIAGNOSIS: Histopathologically, the mass consisted of sheets of hepatocytes, but without the characteristic hepatic architecture. The cells showed moderate variation in nuclear size and were sometimes binucleate. A diagnosis of hepatocellular carcinoma (HCC) in the mesentery was made. The presence of ectopic hepatic tissue has been reported rarely in man and cats, but not in the dog. Neoplastic transformation of ectopic hepatic tissue is seen in man. This is the first report of the presentation, clinical findings and treatment of a dog with ectopic HCC.

    Full Text Available Hepatocellular carcinomas (HCC have different etiology and heterogenic genomic alterations lead to high complexity. The molecular features of HCC have largely been studied by gene expression and proteome profiling focusing on the correlations between the expression of specific markers and clinical data. Integration of the increasing amounts of data in databases has facilitated the link of genomic and proteomic profiles of HCC to disease state and clinical outcome. Despite the current knowledge, specific molecular markers remain to be identified and new strategies are required to establish novel targeted therapies. In the last years, mathematical models reconstructing gene and protein networks based on experimental data of HCC have been developed providing powerful tools to predict candidate interactions and potential targets for therapy. Furthermore, the combination of dynamic and logical mathematical models with quantitative data allows detailed mechanistic insights into system properties. To address effects at the organ level, mathematical models reconstructing the three-dimensional organization of liver lobules were developed. In the future, integration of different modeling approaches capturing the effects at the cellular up to the organ level is required to address the complex properties of HCC and to enable the discovery of new targets for HCC prevention or treatment.

    In this study, it was investigated whether dose response relation existed or not in local radiotherapy for primary hepatocellular carcinoma. From January 1992 to March 2000, 158 patients were included in present study. Exclusion criteria included the presence of extrahepatic metastasis, liver cirrhosis of Child's class C, tumors occupying more than two thirds of the entire liver, and performance status on the ECOG scale of more than 3. Radiotherapy was given to the field including tumor with generous margin using 6, 10-MV X-ray. Mean tumor dose was 48.2±7.9 Gy in daily 1.8 Gy fractions. Tumor response was based on diagnostic radiologic examinations such as CT scan, MR imaging, hepatic artery angiography at 4-8 weeks following completion of treatment. Statistical analysis was done to investigate the existence of dose response relationship of local radiotherapy when it was applied to the treatment of primary hepatocellular carcinoma. An objective response was observed in 106 of 158 patients, giving a response rate of 67. 1%. Statistical analysis revealed that total dose was the most significant factor in relation to tumor response when local radiotherapy was applied to the treatment of primary hepatocellular carcinoma. Only 29.2% showed objective response in patients treated with dose less than 40 Gy, while 68.6% and 77.1 % showed major response in patients with 40-50 Gy and more than 50 Gy, respectively. Child-Pugh classification was significant factor in the development of ascites, overt radiation induced liver disease and gastroenteritis. Radiation dose was an important factor for development of radiation induced gastroduodenal ulcer. Present study showed the existence of dose response relationship in local radiotherapy for primary hepatocellular carcinoma. Only radiotherapy dose was a significant factor to predict the objective response. Further study is required to predict the maximal tolerance dose in consideration of liver function and non-irradiated liver

    Cis-diamminedichloroplatinum II (CDDP; 52-169 mg/m/sup 2/) mixed with angiotensin II (1.5-10 ..mu..g/min) was infused into the hepatic artery in 33 patients with hepatocellular carcinoma. Simultaneously, sodium thiosulfate (10-50 g) was administered intravenously in order to reduce the systemic toxicity of CDDP. Over 50% reduction in tumor size was obtained in 18 patients (55%). Complete response was achieved in 4 patients (12%). Serum alpha-fetoprotein (AFP) levels decreased by more than 75% in 10 of 18 patients in whom the previous AFP level was more than 200 mg/ml. The one year survival rate was estimated at 61% by the Kaplan-Meier method. Alimentary symptoms (nausea, vomiting) were mild or non-existent in nearly 90 per cent of treatments. Peptic ulcer and abdominal pain were manifested in small numbers. Severe changes in the laboratory data were not observed. High dosage arterial infusion of CDDP and angiotensin II and intravenous injection of sodium thiosulfate was well tolerated and gave effective therapy in hepatocellular carcinoma.

Liver CSCs have emerged as an important therapeutic target against HCC. Numerous surface markers for liver CSCs have been identified, and include CD133, CD90, CD44, CD13, and epithelial cell adhesion molecules. These surface markers serve not only as tools for identifying and isolating liver CSCs but also as therapeutic targets for eradicating these cells. In studies of animal models and large-scale genomic analyses of human HCC samples, many signaling pathways observed in normal stem cells have been found to be altered in liver CSCs, which accounts for the stemness and aggressive behavior of these cells. Antibodies and small molecule inhibitors targeting the signaling pathways have been evaluated at different levels of preclinical and clinical development. Another strategy is to promote the differentiation of liver CSCs to less aggressive HCC that is sensitive to conventional chemotherapy. Disruption of the tumor niche essential for liver CSC homeostasis has become a novel strategy in cancer treatment. To overcome the challenges in developing treatment for liver CSCs, more research into the genetic makeup of patient tumors that respond to treatment may lead to more effective therapy. Standardization of HCC CSC tumor markers would be helpful for measuring the CSC response to these agents. Herein, we review the current strategies for developing treatment to eradicate liver CSCs and to improve the outcome for patients with

    To compare the survival rates of patients with hepatoma using different methods of transcatheter arterial chemoemblization(THAE). Four hundred and eighty three patients with hepatoma diagnosed by biopsy, serum alpha-fetoprotein, abdominal CT scan, abdominal ultrasonography or hepatic angiography were included, but not all had received surgical treatment. They were divided onto two groups according to Child's classification and into subgroups according to different methods of THAE. Five-tear survival rates among these groups were retrospectively compared. The patients were aged between 24 and 85(mean, 58) ; male to female ratio was 324 : 61 for those who received THAE (369 : 87 when only hepatic angiography was considered.). In the group with more than a single episode of chemoembolization, regardless of Child's classification, a better survival rate compared to the other groups with or without concommitant radiotherapy or without chemoembolization was noted. There was no difference in the survival rate of patients with multiple chemoembolization. moreover, no difference in this rate was observed no matter what chemotherapeutic agents, including Adriamycin, Cis-Diaminedichloroplatinum of I-131-Lipiodol, were used. Amortization by gelfoam in conjuction with Adriamycin resulted in no difference in survival rate regardless of frequency of chemoembolization. An improved survival rate was seen when multiple episodes of chemoembolization were applied, but no difference was seen when there was concomitant application of either gelfoam or radiotherapy. Two different chemotherapeutic agents, Adriamycin and Cis-Diaminedichloroplatinum, were used, but there was no difference between them in their effect on survival rates.

    To determine efficacy of intrahepatic absolute alcohol injection in researchable hepatocellular carcinoma. A randomized, controlled, experimental and interventional clinical trial. Gastroenterology Department, PGMI, Hayatabad Medical Complex, Peshawar during the period from June, 1998 to June, 2000. Thirty patients were treated by percutaneous, intrahepatic absolute alcohol injection sin repeated sessions, 33 patients were not given or treated with alcohol to serve as control. Both the groups were comparable for age, sex and other baseline characteristics. Absolute alcohol therapy significantly improved quality of life of patients, reduced the tumor size and mortality as well as showed significantly better results regarding survival (P< 0.05) than the patients of control group. We conclude that absolute alcohol is a beneficial and safe palliative treatment measure in advanced hepatocellular carcinoma (HCC). (author)

    Sorafenib is an oral angiogenetic multikinase inhibitor approved in the treatment of renal and hepatocellular carcinoma. Bleeding and venous thrombotic events have been described with angiogenetic agents but cerebrovascular accidents are rarely reported. We report two cases of patients with hepatocellular carcinoma who developed a cerebrovascular accident while on sorafenib. Neither patient had any risk factors for the cerebrovascular events apart from gender and age in the second patient. Laboratory data were noncontributory. The head CT scan did not reveal acute abnormalities. No hemodynamically significant stenosis was visible in the carotid ultrasound, and the echocardiogram showed normal size of the heart chambers and normal systolic function of the left ventricle. Sorafenib was discontinued in both cases. Physicians should monitor patients receiving sorafenib for neurologic symptoms, and in the absence of other etiology, prompt discontinuation of this drug should be considered.

Nine years previously this patient had been diagnosed with HCC and received a right lobectomy. HCC that recurred at the caudate lobe at 6 months after the operation was successfully treated with transarterial chemoembolization. The patient was followed up regularly thereafter without evidence of tumor recurrence for 9 years. In July 2010 his serum alpha-fetoprotein (AFP level elevated from 6.5 ng/mL to 625.4 ng/mL, and he developed a probable single metastatic lymph node around the hepatic artery without intrahepatic lesions. Subsequent evaluation with upper endoscopy revealed a 4-cm ulcerative lesion on the antrum of the stomach. Subtotal gastrectomy was performed with lymph-node dissection. Histologic examination revealed a special type of extrahepatic AFP-producing adenocarcinoma-HAC with lymph-node metastasis-which indicates that HAC can be a cause of elevated AFP even in patients with HCC. HAC should be considered if a patient with stable HCC exhibits unusual elevation of AFP.

    At present, cardiac metastasis of hepatocellular carcinoma is rarely mentioned in the literature. We report a hepatocellular carcinoma patient with cardiac metastasis misdiagnosed as hypertrophic cardiomyopathy in 2011. Two years later, on presentation of syncope, an abnormal ventricular septal size was recorded by ultrasound scan, and was subsequently shown by magnetic resonance imaging to be a tumour lesion. A myocardial biopsy confirmed infiltration of hepatocellular carcinoma. This observation underlines the risk of hepatocellular carcinoma cardiac metastasis, manifested in its infiltrative form as hypertrophic cardiomyopathy. In conclusion, we suggest that the ultrasound appearance of hypertrophic cardiomyopathy in hepatocellular carcinoma patients should be seen as a "red flag" and recommend the introduction of magnetic resonance imaging assessment of transplant candidates.

    Full Text Available Abstract Background Thymostimulin is a thymic peptide fraction with immune-mediated cytotoxicity against hepatocellular carcinoma in vitro. In a phase II trial, we investigated safety and efficacy including selection criteria for best response in advanced or metastasised hepatocellular carcinoma. Methods 44 patients (84 % male, median age 69 years not suitable or refractory to conventional therapy received thymostimulin 75 mg subcutaneously five times per week for a median of 8.2 months until progression or complete response. 3/44 patients were secondarily accessible to local ablation or chemoembolisation. Primary endpoint was overall survival, secondary endpoint tumor response or progression-free survival. A multivariate Cox's regression model was used to identify variables affecting survival. Results Median survival was 11.5 months (95% CI 7.9–15.0 with a 1-, 2- and 3-year survival of 50%, 23% and 9%. In the univariate analysis, a low Child-Pugh-score (p = 0.01, a low score in the Okuda- and CLIP-classification (p Conclusion Outcome in our study rather depended on liver function and intrahepatic tumor growth (presence of liver cirrhosis and Okuda stage in addition to response to thymostimulin, while an invasive HCC phenotype had no influence in the multivariate analysis. Thymostimulin could therefore be considered a safe and promising candidate for palliative treatment in a selected target population with advanced hepatocellular carcinoma, in particular as component of a multimodal therapy concept.

    Transarterial chemoembolization is one of the most widely accepted interventional treatment options for treatment of hepatocellular carcinoma. Still there is a lack of a standard protocol regarding the injected chemotherapeutics. Survivin is an inhibitor of Apoptosis protein that functions to inhibit apoptosis, promote proliferation, and enhance invasion. Survivin is selectively up-regulated in many human tumors. Small interfering RNA (siRNA) can trigger an RNA interference response in mammalian cells and induce strong inhibition of specific gene expression including Survivin. The aim of the study is to assess the effectiveness of the additional injection of Survivin siRNA to the routine protocol of Transarterial Chemoembolization (TACE) for the treatment of hepatocellular carcinoma in a rat model. The study was performed on 20 male ACI rats. On day 0 a solid Morris Hepatoma 3924A was subcapsullary implanted in the liver. On day 12 MRI measurement of the initial tumor volume (V1) was performed. TACE was performed on day 13. The rats were divided into 2 groups; Group (A, n = 10) in which 0.1 mg mitomycin, 0.1 ml lipiodol and 5.0 mg degradable starch microspheres were injected in addition 2.5 nmol survivin siRNA were injected. The same agents were injected in Group (B,=10) without Survivin siRNA. MRI was repeated on day 25 to assess the tumor volume (V2). The tumor growth ratio (V2/V1) was calculated. Western blot and immunohistochemical analysis were performed. For group A the mean tumor growth ratio (V2/V1) was 1.1313 +/− 0.1381, and was 3.1911 +/− 0.1393 in group B. A statistically significant difference between both groups was observed regarding the inhibition of tumor growth (P < 0.0001) where Group A showed more inhibition compared to Group B. Similarly immunohistochemical analysis showed significantly lower (p < 0.002) VEGF staining in group A compared to group B. Western Blot analysis showed a similar difference in VEGF expression (P < 0.0001). The

    Objective: To explore and understand the CT findings of 5 rare histological variants of hepatocellular carcinoma. Methods: CT findings of 31 cases of rare histological variants confirmed by surgery and pathology were analyzed retrospectively. Results: 13 cases were clear cell hepatocellular carcinoma. 3 cases of them showed patchy fat density in plain scans. Enhanced CT showed features of 'fast in fast out' which was similar to the common hepatocellular carcinoma. 4 cases belonged to sclerosis hepatocellular carcinoma. They appeared as heterogeneous, slowly enhancement on arterial phase images, and delay enhancement on portal venous phase and delay phase images. 9 cases belonged to mixed hepatocellular carcinoma. 5 cases of them showed inhomogeneous enhancement and 4 without enhancement during arterial phase, 3 cases showed delay enhancement and 4 without during portal venous and delay phase. 3 cases were fibrolamellar hepatocellular carcinoma. All showed obvious and fastly enhancement on arterial phase images, subsided slowly on the portal venous and delay phase images, showing features of 'fast in slow out', no enhancement was seen in the central scar. Shrinkage phenomenon on the surface of liver could be seen on the CT plain scans in sclerosis, mixed and fibrolamellar hepatocellular carcinoma. 2 cases were the type of dense hepatocellular carcinoma. The surrounding part in the 2 cases were slightly enhanced, while the most part of the center were not enhanced similar to necrosis. Conclusion: The CT findings of rate histological variant of hepatocellular carcinoma are characteristic. Analyzing the CT plain and enhancement finding is helpful to the diagnosis of these types of hepatocellular carcinoma. (authors)

    The opposite effects of chemotherapy, which enhance the malignancy of treated cancers such as hepatocellular carcinoma (HCC), are not well understood. We investigated this phenomenon and corresponding mechanisms to develop a novel approach for improving chemotherapy efficacy in HCC. Human hepatocellular carcinoma cell lines HepG2 (with low metastatic potential) and MHCC97L (with moderate metastatic potential) were used for the in vitro study. An orthotopic nude mouse model of human HCC was developed using MHCC97L cells. We then assessed the metastatic potential of surviving tumor cells after in vitro and in vivo oxaliplatin treatment. The molecular changes in surviving tumor cells were evaluated by western blot, immunofluorescence, and immunohistochemistry. The Chinese herbal extract Songyou Yin (composed of five herbs) was investigated in vivo to explore its effect on the metastatic potential of oxaliplatin-treated cancer cells. MHCC97L and HepG2 cells surviving oxaliplatin treatment showed enhanced migration and invasion in vitro. Residual HCC after in vivo oxaliplatin treatment demonstrated significantly increased metastasis to the lung (10/12 vs. 3/12) when re-inoculated into the livers of new recipient nude mice. Molecular changes consistent with epithelial-mesenchymal transition (EMT) were observed in oxaliplatin-treated tumor tissues and verified by in vitro experiments. The Chinese herbal extract Songyou Yin (4.2 and 8.4 g/kg) attenuated EMT and inhibited the enhanced metastatic potential of residual HCC in nude mice (6/15 vs. 13/15 and 3/15 vs. 13/15, respectively). The surviving HCC after oxaliplatin treatment underwent EMT and demonstrated increased metastatic potential. Attenuation of EMT by Songyou Yin may improve the efficacy of chemotherapy in HCC

    Full Text Available Hepatitis C virus (HCV, a hepatotropic virus, is a single stranded-positive RNA virus of ~9,600 nt. length belonging to the Flaviviridae family. HCV infection causes acute hepatitis, chronic hepatitis, cirrhosis and hepatocellular carcinoma (HCC. It has been reported that HCV-coding proteins interact with host-cell factors that are involved in cell cycle regulation, transcriptional regulation, cell proliferation and apoptosis. Severe inflammation and advanced liver fibrosis in the liver background are also associated with the incidence of HCV-related HCC. In this review, we discuss the mechanism of hepatocarcinogenesis in HCV-related liver diseases.

    Recurrent gastrointestinal bleeding from hepatocellular carcinoma (HCC) invading the duodenum is very rare. We present a case of 50-year-old male who was admitted with a history of recurrent upper gastrointestinal tract (UGIT) bleeding, weight loss and anemia. The patient was known to have a chronic hepatitis C. Endoscopic examination showed grade-2 non-bleeding esophageal varices, and a large ulcerated duodenal mass partially obstructing the duodenal bulb outlet and causing recurrent UGIT bleeding. Pathological evaluation of the mass revealed HCC. (author)

  16. How to detect hepatocellular carcinoma in cirrhosis

    Cirrhosis predisposes to hepatocellular carcinoma (HCC) which develops by sequential steps of de-differentiation of hepatocytes from regenerative nodules via borderline (dysplastic) nodules to frankly malignant HCC. Effective treatment depends on early recognition of HCC, so the key tasks for imaging are firstly recognising the presence of a suspicious lesion, and secondly differentiating between benign, borderline and malignant nodules. Screening of high-risk cirrhotic patients with sonography and measurement of alpha fetoprotein (AFP) is helpful but will not reliably differentiate small HCC from benign or dysplastic nodules. Large HCCs can usually be recognised by their characteristic morphology on imaging, but the appearances of smaller benign and malignant nodules show considerable overlap on unenhanced sonography, CT and MRI. Increasing degrees of histological malignancy are associated with increasing arterialisation and loss of portal blood supply, so the recognition of HCC requires the use of dynamic imaging with contrast-enhanced CT or T1-weighted MRI with gadolinium enhancement. Sonography with microbubble contrast media now offers another method for detecting arterialised nodules; however, some non-malignant nodules show arterial hypervascularity and a minority of HCCs are hypovascular, so the assessment of perfusion does not conclusively distinguish benign from malignant lesions. Kupffer cell function is another attribute of liver tissue which can be explored using MRI with superparamagnetic iron oxide particles (SPIO). Experience thus far suggests that uptake of SPIO is an effective discriminator between benign and malignant nodules. The combination of SPIO with gadolinium-enhanced MRI offers the opportunity for imaging characterisation of cirrhotic nodules by cellular function as well as by blood supply, and this approach is now proposed as the examination of choice for detecting HCC in cirrhosis.

    Currently, using biopsy specimens to confirm suspicious liver lesions of early hepatocellular carcinoma are not entirely reliable because of insufficient sampling amount and inaccurate sampling location. It is necessary to develop a signature to aid early hepatocellular carcinoma diagnosis using biopsy specimens even when the sampling location is inaccurate. Based on the within-sample relative expression orderings of gene pairs, we identified a simple qualitative signature to distinguish both hepatocellular carcinoma and adjacent non-tumour tissues from cirrhosis tissues of non-hepatocellular carcinoma patients. A signature consisting of 19 gene pairs was identified in the training data sets and validated in 2 large collections of samples from biopsy and surgical resection specimens. For biopsy specimens, 95.7% of 141 hepatocellular carcinoma tissues and all (100%) of 108 cirrhosis tissues of non-hepatocellular carcinoma patients were correctly classified. Especially, all (100%) of 60 hepatocellular carcinoma adjacent normal tissues and 77.5% of 80 hepatocellular carcinoma adjacent cirrhosis tissues were classified to hepatocellular carcinoma. For surgical resection specimens, 99.7% of 733 hepatocellular carcinoma specimens were correctly classified to hepatocellular carcinoma, while 96.1% of 254 hepatocellular carcinoma adjacent cirrhosis tissues and 95.9% of 538 hepatocellular carcinoma adjacent normal tissues were classified to hepatocellular carcinoma. In contrast, 17.0% of 47 cirrhosis from non-hepatocellular carcinoma patients waiting for liver transplantation were classified to hepatocellular carcinoma, indicating that some patients with long-lasting cirrhosis could have already gained hepatocellular carcinoma characteristics. The signature can distinguish both hepatocellular carcinoma tissues and tumour-adjacent tissues from cirrhosis tissues of non-hepatocellular carcinoma patients even using inaccurately sampled biopsy specimens, which can aid early

    The author proposed improvement of the criteria for the effects of transcatheter therapy for hepatocellular carcinoma. 104 patients were treated by transcatheter therapy. Their responses were determined by the usual criteria. Next, they were classified and evaluated in 3 groups, with the area of lipiodol deposition on CT for over 4 weeks regarded as nacrosis. The result was determined, and its relationship to prognosis was studied in light of the repeated therapy. By the usual criteria, only 10% of patients were judged as PR, and there were no differences between therapies. Many of the NC cases had low AFP levels with therapy. At the initial therapy, the ratio of cases with low AFP levels was higher and the survival time was longer in the A group. So the A group was judged as most effective. Clinically, 10 patients were considered most benefitted by therapy. They were considered the A group, but all were judged as NC. Considering the effects of repeated therapy, 10 patients with NC were judged as the A-max group. Prognosis was poor in patients of the B-max and C-max groups. These results indicate that judgement by the usual criteria was inconsistent with clinical condition. It was improved by regarding the area of lipiodol deposition on CT for over 4 weeks as necrosis. Estimations of effects and prognosis were made more accurate by considering repeated therapy. Thus, the proposed improvement of the criteria by CT is more useful to estimate transcatheter therapy of the hepatocellular carcinoma. (author)

    Forty three cases of small hepatocellular carcinoma (measuring less than 3 cm in diameter on imaging modalities) were detected during a period of four years and two months. There were two cases in which hepatoma measured 1 cm in diameter, twenty four cases between 1 and 2 cm, and seventeen cases between 2 and 3 cm. The relative role of each modality and AFP value in the detection of these tumors was evaluated. The detection rate of small hepatocellular carcinoma by liver scintigraphy, ultrasonography (US), computed tomography (CT) and angiography was 8%, 74%, 70% and 95%, respectively. The sensitivity of serum AFP value was 67% (either measuring more than 200ng/ml or showing a tendency of steady rising even if below the level of 200ng/ml). Most hepatomas less than 2 cm in size were hypoechoic on US, and those above 2 cm in size were hyperechoic with peripheral sonolucency (halo). Almost all cases were described as low density area on both plain and enhancement CT. Angiography was the best method for detecting small hepatomas. It may be recommended to perform angiography on every patient with liver cirrhosis at the time of diagnosis of this disease. Periodic examinations by AFP, US and CT should be done if the angiography was negative. Evaluation by US in every three months and by CT in every twelve months may be appropriate.

    In order to detect and to evaluate the frequency, the distribution, and the radiological findings of skeletal metastases from hepatocellular carcinoma, the authors retrospectively analyzed radiographic, scintigraphic, and CT findings of 257 patients with hepatocellular carcinoma. The results were as follows: 1. Skeletal metastases were demonstrated in 21 patients (8.2%). 2. Frequent symptoms were pain, limitation of motion, paralysis, and mass. In nine of them the initial symptoms were due to skeletal metastases. 3. The common sites of metastases were spine (13 cases), ribs (8 cases), pelvis (8 cases) and femur (6 cases). Humerus, skull and sternum were also frequently involved. 4. Plain film findings were purely osteolytic in all cases and pathologic fractures were noted in 5 cases. 5. The lesions appear expansible in 7 cases, and 4 of them showed associated soft tissue masses on CT scans. 6. Bone scans were performed in 13 cases of them and showed increased radiotracer uptake in all. 7. Angiographic studies of 3 cases showed hypervascularity of the metastatic lesions as well as the primary hepatic tumor.

    Full Text Available More and more clinical trials have proved the efficacy of targeted drugs in the treatment of hepatocellular carcinoma (HCC. With the development of science and technology, more and more targeted drugs have appeared. In recent years, targeted drugs such as regorafenib and ramucirumab have shown great potential in related clinical trials. In addition, there are ongoing clinical trials for second-line candidate drugs, such as c-Met inhibitors tivantinib and cabozantinib and a VEGFR-2 inhibitor ramucirumab. This article summarizes the advances in targeted drug therapy for HCC and related trial data, which provides a reference for further clinical trials and treatment.

    Fibrolamellar carcinoma (FLC) has been considered a distinct clinical entity vs. hepatocellular carcinoma, with respect to its epidemiology, etiology, and prognosis. We describe the unusual case of a 23-year-old female patient with FLC and ovarian (Krukenberg) and peritoneal metastases, clinically mimicking an ovarian carcinoma. Multiple recurrences occurred despite initial R0 resection and chemotherapy, requiring surgical treatment. The patient survived five years and died from generalized disease. The particularities of our case are discussed by comparison with the other two similar cases and other date from the literature. To our knowledge, the ovarian involvement encountered in our case is the third case published in literature, being explained by the superficial location of the liver tumor.

    The insufficient cellular uptake of nanocarriers and their slow drug release have become major obstacles for achieving satisfactory anticancer outcomes in nano-medicine therapy. Because of the slightly acidic extracellular environment (pHe ~ 6.5) and a higher glutathione (GSH) concentration (approximately 10 mM) in tumor tissue/cells, we firstly designed a novel d-α-tocopheryl polyethylene glycol 1000-poly(β-amino ester) block copolymer containing disulfide linkages (TPSS). TPSS nanoparticles (NPs) with pH- and redox-sensitive behaviors were developed for on-demand delivery of docetaxel (DTX) in hepatocellular carcinoma. DTX/TPSS NPs exhibited sensitive surface charge reversal from -47.6 +/- 2.5 mV to +22.5 +/- 3.2 mV when the pH decreased from 7.4 to 6.5, to simulate the pHe. Meanwhile, anabatic drug release of DTX/TPSS NPs was observed in PBS buffer (pH 6.5, 10 mM GSH). Due to the synergism between the pHe-triggered charge reversal and the redox-triggered drug release, enhanced drug uptake and anticancer efficacy were observed in HepG2 and SMMC 7721 cells treated with DTX/TPSS NPs. The positively charged NPs exhibited a stronger inhibitory effect on cell proliferation, promoted cell cycle arrest in the G2/M phase, and increased the rate of apoptosis. More importantly, based on the higher tumor accumulation of TPSS vehicles in vivo, a significant suppression of tumor growth, but without side-effects, was observed when DTX/TPSS NPs were injected intravenously into HepG2 xenograft tumor-bearing mice. Collectively, these results demonstrate that the newly developed dual-functional TPSS copolymer may be utilized as a drug delivery system for anticancer therapy.The insufficient cellular uptake of nanocarriers and their slow drug release have become major obstacles for achieving satisfactory anticancer outcomes in nano-medicine therapy. Because of the slightly acidic extracellular environment (pHe ~ 6.5) and a higher glutathione (GSH) concentration (approximately 10 m

    PurposeThis study was designed to evaluate the efficacy and safety in performing chemoembolization of extrahepatic collateral arteries (EHC) for hepatocellular carcinoma (HCC) located in the caudate lobe.MethodsBetween January 2006 and November 2013, chemoembolization via EHC was performed in 35 patients with 35 caudate HCCs. Preprocedural and follow-up CT or MR scans, angiographic images, and medical records were reviewed retrospectively in consensus. Chi-square analysis was used to evaluate the relationship between tumor characteristics and type of EHC and that between tumor response and the characteristics of the tumor and chemoembolization.ResultsIn 31 (88.6 %) patients, EHCs supplying the caudate HCC originated from the right inferior phrenic artery (RIPA). The remaining four HCCs were supplied by the gastroduodenal artery, dorsal pancreatic artery, and right and left gastric arteries. Superselective catheterization of tumor-feeding vessels from the EHC was achieved in 27 patients (77.1 %). There were no major complications. Individual tumor response supplied by the EHC at follow-up contrast-enhanced CT were as follows: complete response (n = 18), partial response (n = 9), stable disease (n = 3), and progressive disease (n = 3). Non-RIPA EHCs were significantly more common in patients who had previously received chemoembolization via the RIPA (50 %) than those who had not (6.5 %; P = 0.01). There was no significant predictive factor associated with tumor response.ConclusionsHCC in the caudate lobe can be supplied by several EHCs. Chemoembolization via these arteries can be performed safely and effectively

    Mitochondrial dynamics of fission and fusion plays critical roles in a diverse range of important cellular functions, and its deregulation has been increasingly implicated in human diseases. Previous studies have shown that increased mitochondrial fission significantly promoted the proliferation of hepatocellular carcinoma (HCC) cells. However, how they influence the migration of tumour cells remained largely unknown. In the present study, we further investigated the effect of mitochondrial fission on the migration and metastasis of hepatocellular carcinoma cells. Moreover, the underlying molecular mechanisms and therapeutic application were explored. Our data showed that dynamin-1-like protein expression was strongly increased in distant metastasis of hepatocellular carcinoma when compared to primary hepatocellular carcinoma. In contrast, the mitochondrial fusion protein mitofusin 1 showed an opposite trend. Moreover, the expression of dynamin-1-like protein and mitofusin 1 was significantly associated with the disease-free survival of hepatocellular carcinoma patients. In addition, our data further showed that mitochondrial fission significantly promoted the reprogramming of focal-adhesion dynamics and lamellipodia formation in hepatocellular carcinoma cells mainly by activating typical Ca 2+ /CaMKII/ERK/FAK pathway. Importantly, treatment with mitochondrial division inhibitor-1 significantly decreased calcium signalling in hepatocellular carcinoma cells and had a potential treatment effect for hepatocellular carcinoma metastasis in vivo. Taken together, our findings demonstrate that mitochondrial fission plays a critical role in the regulation of hepatocellular carcinoma cell migration, which provides strong evidence for this process as a drug target in hepatocellular carcinoma metastasis treatment. © 2017 John Wiley & Sons A/S.

    Sorafenib is an oral multikinase inhibitor that has been proven effective as a single-agent therapy in hepatocellular carcinoma, and there is a strong rationale for investigating its use in combination with other agents. Vitamin K2 is nearly non-toxic to humans and has been shown to inhibit the growth of hepatocellular carcinoma. In this study, we evaluated the effects of a combination of sorafenib and vitamin K2 on the growth of hepatocellular carcinoma cells. Flow cytometry, 3-(4,5-dimethyl-2-thiazolyl-2,5-diphenyl-2H-tetrazolium bromide) and nude mouse xenograft assays were used to examine the effects of sorafenib and vitamin K2 on the growth of hepatocellular carcinoma cells. Western blotting was used to elucidate the possible mechanisms underlying these effects. Assays for 3-(4,5-dimethyl-2-thiazolyl-2,5-diphenyl-2H-tetrazolium bromide) revealed a strong synergistic growth-inhibitory effect between sorafenib and vitamin K2. Flow cytometry showed an increase in cell cycle arrest and apoptosis after treatment with a combination of these two drugs at low concentrations. Sorafenib-mediated inhibition of extracellular signal-regulated kinase phosphorylation was promoted by vitamin K2, and downregulation of Mcl-1, which is required for sorafenib-induced apoptosis, was observed after combined treatment. Vitamin K2 also attenuated the downregulation of p21 expression induced by sorafenib, which may represent the mechanism by which vitamin K2 promotes the inhibitory effects of sorafenib on cell proliferation. Moreover, the combination of sorafenib and vitamin K2 significantly inhibited the growth of hepatocellular carcinoma xenografts in nude mice. Our results determined that combined treatment with sorafenib and vitamin K2 can work synergistically to inhibit the growth of hepatocellular carcinoma cells. This finding raises the possibility that this combined treatment strategy might be promising as a new therapy against hepatocellular carcinoma, especially for patients

    Hepatocellular carcinomas exhibit heterogeneous morphologies by routine light microscopy. Although some morphologies represent insignificant variations in growth patterns, others may represent unrecognized subtypes of hepatocellular carcinoma. Identification of these subtypes could lead to separation of hepatocellular carcinomas into discrete groups with unique underlying genetic changes, prognosis, or therapeutic responses. In order to identify potential subtypes, two pathologists independen...

    Lifestyle factors such as smoking, obesity and physical activity have gained interest in the field of hepatocellular carcinoma. These factors play a significant role in the development of hepatocellular carcinoma. Several studies revealed the impact of tobacco consumption on the development of hepatocellular carcinoma and its synergistic effects with viral etiologies (hepatitis B and C). The effects of smoking on survival in patients with a diagnosed hepatocellular carcinoma have not yet been investigated in a Western cohort where hepatitis C infection is a major risk factor. Using data from a prospective cohort of patients with hepatocellular carcinoma who were followed at the University Hospital of Bern, Switzerland, survival was compared by Kaplan-Meier analysis in smokers and nonsmokers, and multivariate Cox regression was applied to control for confounding variables. Of 238 eligible hepatocellular carcinoma patients, 64 were smokers at the time of inclusion and 174 were nonsmokers. Smokers had a significant worse overall survival than nonsmokers (hazard ratio 1.77, 95% confidence interval: 1.22-2.58, P=.003). Analysis of patients according to their underlying liver disease, revealed that smoking, and not nonsmoking, affected survival of hepatitis B virus and C virus-infected patients only. In this subgroup, smoking was an independent predictor for survival (hazard ratio 2.99, 95% confidence interval: 1.7-5.23, Phepatocellular carcinoma. © 2017 John Wiley & Sons A/S.

    2012-02-01

    Early diagnosis and treatment of the respiratory and gastrointestinal complications of cystic fibrosis (CF) have led to improved survival with many patients living beyond the fourth decade. Along with this increased life expectancy is the risk of further disease associated with the chronic manifestations of their condition. We report a patient with documented CF related liver disease for which he was under routine surveillance that presented with histologically proven hepatocellular carcinoma (HCC). It is important that physicians are aware of this association as increased vigilance may lead to earlier diagnosis and perhaps, a better outcome.

    Extra-hepatic spread is present in 5% to 15% of patients with hepatocellular carcinoma (HCC) at the time of diagnosis. The most frequent sites are lung and regional lymph nodes. Here, we report 3 cases of unsuspected HCC with symptoms due to bone lesions as initial presentation. Morphological characteristics and immunohistochemistry from the examined bone were the key data for diagnosis. None of the patients had an already known chronic liver disease. Differential diagnoses with HCC upon ectopic liver disease or hepatoid adenocarcinoma were shown. Therapy with the orally active multikinase inhibitor sorafenib plus symptomatic treatment was indicated.

    Objective: To evaluate radiology and embolization for hepatocellular carcinoma supplied by gonadal artery. Methods: The medical records of 3 patients with hepatocellular carcinoma supplied by gonadal artery from August 2002 to September 2008 were reviewed. The demography, gonadal artery location, modus operandi, imaging features of liver cancer and prognosis were retrospectively analyzed. Results: Anatomic variation of gonadal artery occurred with the gonadal artery arising from the upper abdominal aorta in 1 patient and from the middle suprarenal artery in 2 patients. The blood supply of the hepatocellular carcinoma derived from the gonadal artery in all 3 patients. No complications occurred in the 6-month follow-up after embolization. Conclusion: Hepatocellular carcinoma may be supplied by gonadal artery with anomalous origin. This anatomic variant can be readily demonstrated by imaging to guide embolization. (authors)

    Full Text Available Radiological imaging plays a crucial role in the diagnosis of hepatocellular carcinoma (HCC as the noninvasive diagnosis of HCC in high-risk patients by typical imaging findings alone is widely adopted in major practice guidelines for HCC. While imaging techniques have markedly improved in detecting small liver lesions, they often detect incidental benign liver lesions and non-hepatocellular malignancy that can be misdiagnosed as HCC. The most common mimicker of HCC in cirrhotic liver is nontumorous arterioportal shunts that are seen as focal hypervascular liver lesions on dynamic contrast-enhanced cross-sectional imaging. Rapidly enhancing hemangiomas can be easily misdiagnosed as HCC especially on MR imaging with liver-specific contrast agent. Focal inflammatory liver lesions mimic HCC by demonstrating arterial-phase hypervascularity and subsequent washout on dynamic contrast-enhanced imaging. It is important to recognize the suggestive imaging findings for intrahepatic cholangiocarcinoma (CC as the management of CC is largely different from that of HCC. There are other benign mimickers of HCC such as angiomyolipomas and focal nodular hyperplasia-like nodules. Recognition of their typical imaging findings can reduce false-positive HCC diagnosis.

    Thirty cases of pathologically confirmed small hepatocellular carcinoma were examined by Incremental Dynamic CT (ICT). ICT scanned the whole liver with single-breath-hold technique; therefore, effective early contrast enhancement could be obtained for diagnosis. Among the 30 tumors, 26 were detected. The detection rate was 87%. A high detection rate was obtained in tumors more than 20 mm in diameter. Twenty-two of 26 tumors could be diagnosed correctly. ICT examination was useful for detection of small hepatocellular carcinoma. (author)

    Wilson disease is caused by the accumulation of copper in the liver, brain or other organs, due to the mutation in ATP7B gene, which encodes protein that helps in excretion of copper in the bile canaliculus. Clinical presentation varies from asymptomatic elevation of transaminases to cirrhosis with decompensation. Hepatocellular carcinoma is a known complication of cirrhosis, but a rare occurrence in Wilson disease. We present a case of neurological Wilson disease, who later developed decompensated cirrhosis and hepatocellular carcinoma.

    In order to evaluate the diagnostic ability of CT in hepatocellular carcinoma, four kinds of CT images were comparatively studied by the accuracy and ROC (receiver operating characteristic) curve analysis. As a result, it was clarified that CT images were evaluated more objectively by ROC curve analysis than by accuracy. The diagnostic ability of existence and differentiation of tumor in the liver were higher in order of plain CT, contrast enhanced CT (CECT), bolus CT and CT arteriography (CTA). Therefore, in an usual CT examination intended to make differential diagnosis in space occupying liver disease, bolus CT seems to be indispensable, and also CTA is essential where diagnosis is difficult even by bolus CT.

    2008-09-01

    Hepatocellular carcinoma (HCC) ranks fifth in frequency of cancers worldwide. The incidence of HCC in the United States is rising, primarily due to the number of patients who were infected by hepatitis in the 1960s and 1970s coupled with the rising migrant population from Asia, where hepatitis is widely prevalent. Up to 80% of the patients present with multicentric HCC and advanced liver disease or comorbidities that restrict the option of resection or liver transplantation. The dual blood supply (arterial and portal) to the liver with predominantly arterial supply to the tumor has made embolotherapy a cornerstone in the management of inoperable HCC. The techniques have become refined not only due to the development of microcatheter angiographic capabilities, but also in the ability to deliver a wide variety of therapeutic agents to these tumors. This article reviews the fundamental principles of bland embolization, chemoembolization, and radioembolization in the management of HCC.

    1985-01-01

    This study assesses the diagnostic value of Lipiodol (iodized oil) and computed tomography (CT) in detecting hepatocellular carcinoma (HCC). Twenty-four patients who were suspected of having HCC received injections of a small amount of Lipiodol, along with an antitumor agent, in the hepatic artery following routine celiac angiography. CT scans obtained 7-10 days after Lipiodol administration demonstrated HCC in distinct contrast to the surrounding noncancerous parenchyma. In particular, the CT-Lipiodol procedure disclosed many small HCC lesions that were not shown by celiac angiography, scintigraphy, CT with an without contrast medium enhancement, and ultrasonography. Although this procedure may miss very small or highly fibrotic lesions, it is recommended for patients suspected of having HCC and for patients for whom hepatic resection is being considered

    2014-01-01

    Purpose: To assess the interobserver agreement in 50 patients with hepatocellular carcinoma (HCC) before and 1 month after intra-arterial therapy (IAT) using two semi-automated methods and a manual approach for the following functional, volumetric and morphologic parameters: (1) apparent diffusion coefficient (ADC), (2) arterial phase enhancement (AE), (3) portal venous phase enhancement (VE), (4) tumor volume, and assessment according to (5) the Response Evaluation Criteria in Solid Tumors (RECIST), and (6) the European Association for the Study of the Liver (EASL). Materials and methods: This HIPAA-compliant retrospective study had institutional review board approval. The requirement for patient informed consent was waived. Tumor ADC, AE, VE, volume, RECIST, and EASL in 50 index lesions was measured by three observers. Interobserver reproducibility was evaluated using intraclass correlation coefficients (ICC). P < 0.05 was considered to indicate a significant difference. Results: Semi-automated volumetric measurements of functional parameters (ADC, AE, and VE) before and after IAT as well as change in tumor ADC, AE, or VE had better interobserver agreement (ICC = 0.830–0.974) compared with manual ROI-based axial measurements (ICC = 0.157–0.799). Semi-automated measurements of tumor volume and size in the axial plane before and after IAT had better interobserver agreement (ICC = 0.854–0.996) compared with manual size measurements (ICC = 0.543–0.596), and interobserver agreement for change in tumor RECIST size was also higher using semi-automated measurements (ICC = 0.655) compared with manual measurements (ICC = 0.169). EASL measurements of tumor enhancement in the axial plane before and after IAT ((ICC = 0.758–0.809), and changes in EASL after IAT (ICC = 0.653) had good interobserver agreement. Conclusion: Semi-automated measurements of functional changes assessed by ADC and VE based on whole-lesion segmentation demonstrated better reproducibility than

    1982-09-15

    It is well known that CT is very useful in the evaluation of hepatocellular carcinoma. The computed tomographic findings of 56 patients diagnosed as hepatocellular carcinoma were reviewed and analyzed. The results were as follows: 1. The male to female ratio was 3 : 1 and the age ranged from 31 to 73 years with average age of 54 years. 2. Alpha-fetoprotein was positive in 19 out of 38 cases (50%). HBsAg was positive in 8 out of 33 cases (24%). 3. All lesions were seen as areas of low density except 1 case (0%) of isodensity, and 40 cases (72%) appeared to be solitary while 15 (26%) were multifocal. The low density was homogenous in 13 cases (24%) and inhomogenous in 42 cases (76%), and 18 cases out of 42 cases inhomogenous low density showed peripheal and/or central nodular enhancement. The additional findings were contour changes in 37 cases (66%), metastasis in 35 cases (63%), splenomegaly in 23 cases (42%) and ascities in 22 cases (39%). 4. In postcontrast scans, 41 cases (80%) out of 51 cases showed the change of density after contrast infusion. The presence and extent of tumors were better seen after contrast infusion in 30 cases (59%), better seen before contrast infusion in 11 cases (21%) and no significant difference before and after contrast infusion in 10 cases (20%). 5. The sites of involved lobe were right lobe in 38 cases (68%), left lobe in 5 cases (9%) and both lobes in 13 cases (23%). 6. 35 cases (63%) showed evidence of metastasis to regional lymph nodes, organ or tissues.

    Radiofrequency ablation (RFA) is a minimally invasive procedure that has been considered as a relatively safe treatment for patients with small hepatocellular carcinoma (HCC). However, RFA has been shown to be associated with complications including mechanical and thermal damage. A 74-year-old man with hepatitis C virus-associated HCC was admitted to our hospital. Abdominal computed tomography revealed two lobulated-HCC in segments 4 and 5. He had no medical history of hypertension and cardiac disease. During RFA, blood pressure was elevated to 200/140 mmHg. There was no evidence of pulmonary embolism, aortic dissection, or ischemic heart disease. Laboratory findings for catecholamine surge were all within normal limits. After continuous intravenous nitroglycerin and oral beta-blocker treatment, patient's blood pressure gradually decreased and back within the normal range. Hypertensive crisis after RFA treatment for HCC is rare. Most reported cases of hypertensive crisis during RFA were related to adrenal gland injury with a release of catecholamine. In our case, the site of HCC was not close to the adrenal gland, and there was no evidence of catecholamine surge. Herein, we report a very rare case of hypertensive crisis without a surge in adrenal hormones after RFA treatment for HCC.

    Hepatocellular carcinoma is a major public health problem with one of the highest overall mortality compared to other cancers. The median overall survival in France in a hospital population with hepatocellular carcinoma is 9.4 months. Several publications reported a positive impact of hepatocellular carcinoma screening on diagnosis at an early-stage, eligibility for curative treatment and overall survival. However, the identification of patients to be included in a hepatocellular carcinoma screening program and the application of screening recommendations are not optimal. Other studies suggest a potentially negative impact of delayed diagnosis or treatment initiation on the patient's prognosis. Finally, marked variations between French regions and departments have been described in terms of access to curative treatment and overall survival. In this review article, we propose a state of play of the hepatocellular carcinoma patient's care pathway in France with the aim of identifying potential breaking points with negative impact on prognosis and of developing proposals for improvement.

    Objective: The objective is to study the technology associated with and feasibility of the treatment of hepatocellular carcinoma (HCC) adjacent to large blood vessels using 1.5T MRI-guided radiofrequency ablation combined with iodine-125 (I-125) radioactive seed implantation. Methods: Sixteen patients with a total of 24 HCC lesions (average maximum diameter: 2.35 {+-} 1.03 cm) were pathologically confirmed by biopsy or clinically diagnosed received 1.5T MRI-guided percutaneous radiofrequency ablation (RFA) treatment. Each patient had one lesion adjacent to large blood vessels ({>=}3 mm); after the ablation, I-125 radioactive seeds were implanted in the portions of the lesions that were adjacent to the blood vessels. Results: All the ablations and I-125 radioactive seed implantations were successful; a total of 118 seeds were implanted. The ablated lesions exhibited hypointense signals on the T2WI sequence with a thin rim of hyperintense signals; they also exhibited significant hyperintense signals on the T1WI sequence with clear boundaries. The average follow-up period was 11.1 {+-} 6.2 months. There were 23 complete responses and one partial response in the 24 lesions. The alpha-fetoprotein (AFP) levels of the patients significantly decreased. Conclusion: The 1.5T MRI-guided RFA combined with I-125 radioactive seed implantation for the treatment of HCC adjacent to large blood vessels is an effective technology.

  12. Interstitial Fluid Flow Increases Hepatocellular Carcinoma Cell Invasion through CXCR4/CXCL12 and MEK/ERK Signaling

    Science.gov (United States)

    2015-01-01

    Hepatocellular carcinoma (HCC) is the most common form of liver cancer (~80%), and it is one of the few cancer types with rising incidence in the United States. This highly invasive cancer is very difficult to detect until its later stages, resulting in limited treatment options and low survival rates. There is a dearth of knowledge regarding the mechanisms associated with the effects of biomechanical forces such as interstitial fluid flow (IFF) on hepatocellular carcinoma invasion. We hypothesized that interstitial fluid flow enhanced hepatocellular carcinoma cell invasion through chemokine-mediated autologous chemotaxis. Utilizing a 3D in vitro invasion assay, we demonstrated that interstitial fluid flow promoted invasion of hepatocellular carcinoma derived cell lines. Furthermore, we showed that autologous chemotaxis influences this interstitial fluid flow-induced invasion of hepatocellular carcinoma derived cell lines via the C-X-C chemokine receptor type 4 (CXCR4)/C-X-C motif chemokine 12 (CXCL12) signaling axis. We also demonstrated that mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling affects interstitial fluid flow-induced invasion; however, this pathway was separate from CXCR4/CXCL12 signaling. This study demonstrates, for the first time, the potential role of interstitial fluid flow in hepatocellular carcinoma invasion. Uncovering the mechanisms that control hepatocellular carcinoma invasion will aid in enhancing current liver cancer therapies and provide better treatment options for patients. PMID:26560447

    Widespread or high-frequency microsatellite instability (MSI) due to the defective DNA mismatch repair (MMR) occurs in the majority of hereditary non-polyposis colorectal cancer and a subset of sporadic malignant tumors. The incidence of MSI and underlying DNA MMR defects have been well characterized in gastrointestinal carcinogenesis, but not in hepatocarcinogenesis. To address the issue, we analyzed 55 Japanese hepatocellular carcinomas using several indicators of DNA MMR defects, such as microsatellite analysis, loss of heterozygosity (LOH) and mutation analysis of MMR genes, methylation of hMLH1 promoter, and frameshift mutations of mononucleotide repeat sequences within possible target genes. Mutation of beta2-microglobulin gene, which is presumably involved in MSI-positive tumor cell escape from immune surveillance was also examined. Some of these analyses were also carried out in 9 human liver cancer cell lines. None of the 3 quasi-monomorphic mononucleotide markers sensitive for MSI, BAT26, BAT25, and BAT34C4 presented shortened unstable alleles in any of the carcinoma, cirrhosis, chronic hepatitis tissues, or cell lines. LOH at MMR genes was infrequent (4.4 approximately 7.1%), and no mutations were detected. Neither hMLH1 hypermethylation nor frameshift mutation in the target genes was detected. No mutations were found in beta2-microglobulin. Widespread MSI due to the defective DNA MMR appears to play little if any part in Japanese hepatocarcinogenesis.

    2004-01-01

    Post-embolization syndrome (PES) occurs in most patients who undergo trans-catheter arterial chemoembolization (TACE) for treatment of unresectable hepatocellular carcinoma (HCC). Intra-hepatic arterial administration of TheraSphere, yttrium-90 glass microspheres, is an alternative treatment for unresectable HCC that does not require embolization of major vessels and may have a more favorable toxicity profile than TACE. This paper compares the incidence of PES after TACE vs. TheraSphere treatment in unresectable HCC patients. Data for 29 TACE-treated and 34 TheraSphere-treated patients were evaluated for PES. PES toxicities (i.e., nausea, vomiting, fever in the absence of infection, and abdominal pain) were scored according to Southwest Oncology Group (SWOG) toxicity criteria. PES was defined as a total score for the four toxicities of 2 or greater. Survival was defined from the date of treatment to the date of death. TACE patients underwent one to seven treatment procedures; TheraSphere patients underwent one to two treatment procedures. The incidence of PES was 3.8-times (95% confidence interval 1.6-16.3) higher after TACE [20/29(69%)] than after TheraSphere [6/34 (18%)] treatment; this difference was statistically significant (p=.003). Median survival was similar for TheraSphere (N=20; 378 days, CI 209-719) and TACE (N=29; 343 days, CI 217-511) patients. It was concluded that treatment of unresectable HCC with TheraSphere results in a much lower incidence of PES compared to TACE. Since TheraSphere is a pure beta emitter; it can potentially be administered safely on an outpatient basis, and appears to be at least as efficacious as TACE on survival with fewer treatments per patient.

    To evaluate the diagnostic utility of Hep par-1 in differentiating hepatocellular carcinoma from metastatic carcinoma taking histopathology as a gold standard. Study Design: Comparative cross-sectional study. Place and Duration of Study: Pathology Department, Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, from April 2007 to February 2008. Methodology: Hep par-1 immunohistochemical stain was performed on 60 cases of liver carcinoma, 30 cases each of metastatic and hepatocellular carcinoma. Information regarding patient age, gender, sign and symptoms, radiographic findings, histological grade of tumour, and expression of Hep par-1 on hepatocellular and metastatic carcinoma were recorded on proforma sheet. Sensitivity, specificity, positive and negative predictive values, and accuracy of Hep par-1 were calculated using the formulas. Results: Hep par-1 expression was noted in 25 out of 30 cases of hepatocellular carcinoma (83%). Out of 30 cases of metastatic carcinoma, only one case expressed staining in < 5% tumour cells and remaining 29 cases showed no reactivity. The age of the patients with hepatocellular carcinoma ranged from 40 to 76 years with a median age of 60.5 years and 40 - 75 years for metastatic carcinomas with a median age of 57.5 years. Conclusion: Hep par-1 is a reliable immunohistochemical marker for cases of hepatocellular carcinoma (HCC). It can be used along with other markers in morphologically difficult cases when differential diagnosis lies between poorly differentiated HCC and metastatic carcinoma of liver. (author)

    The combination of a multi-therapeutic mode with a controlled fashion is a key improvement in nanomedicine. Here, we synthesized polyethylene glycol (PEG)-modified doxorubicin (DOX)-loaded mesoporous silica nanoparticle (MSN) @CuS nanohybrids as efficient drug delivery carriers, combined with photothermal therapy and chemotherapy to enhance the therapeutic efficacy on hepatocellular carcinoma (HCC). The physical properties of the nanohybrids were characterized by transmission electron microscopy (TEM), N2 adsorption and desorption experiments and by the Vis-NIR absorption spectra. The results showed that the doxorubicin could be stored in the inner pores of mesoporous silica nanoparticles; the CuS nanoparticles, which are coated on the surface of a mesoporous silica nanoparticle, could serve as efficient photothermal therapy (PTT) agents; the loaded drug release could be easily triggered by NIR irradiation. The combination of the PTT treatment with controlled chemotherapy could further enhance the cancer ablation ability compared to any of the single approaches alone. Hence, the reported PEG-modified DOX-loaded mesoporous silica nanoparticle@CuS nanohybrids might be very promising therapeutic agents for HCC treatment.

    To correlate early changes in the parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) within 1 week of systemic therapy with overall survival (OS) in patients with advanced hepatocellular carcinoma (HCC). Eighty-nine patients with advanced HCC underwent DCE-MRI before and within 1 week following systemic therapy. The relative changes of six DCE-MRI parameters (Peak, Slope, AUC, Ktrans, Kep and Ve) of the tumours were correlated with OS using the Kaplan-Meier model and the double-sided log-rank test. All patients died and the median survival was 174 days. Among the six DCE-MRI parameters, reductions in Peak, AUC, and Ktrans, were significantly correlated with one another. In addition, patients with a high Peak reduction following treatment had longer OS (P = 0.023) compared with those with a low Peak reduction. In multivariate analysis, a high Peak reduction was an independent favourable prognostic factor in all patients [hazard ratio (HR), 0.622; P = 0.038] after controlling for age, sex, treatment methods, tumour size and stage, and Eastern Cooperative Oncology Group performance status. Early perfusion changes within 1 week following systemic therapy measured by DCE-MRI may aid in the prediction of the clinical outcome in patients with advanced HCC. (orig.)

    Hepatocellular carcinoma (CHC) is one of the leading causes of worldwide cancer mortality. The aim of this study is to describe the clinical and epidemiological characteristics, as well as treatment prescribed in patients with this diagnosis. Longitudinal and prospective study that included patients with diagnosis of CHC in the Department of Digestive System at the HNERM-EsSalud between august 2007 and august 2008. We included 36 patients, median age was 60,1 years and 61,1% were male. Cirrhosis was present in 69,1% and median age in this group was 68,9 years, the median age in those without cirrhosis was 40 years (pChild-Pugh score B or C. Symptomatic treatment was prescribed in 44,4% of the patients. Epidemiological features are different between patients with or without cirrhosis. In the first case their characteristics are similar to those described in areas of low risk for CHC; in the second group the characteristics are similar to those described in areas with high risk population. CHC has frequent association with hepatitis B virus. High percentage of patients is diagnosed with an advanced stage of HCC.

    Sorafenib is widely used for unresectable and metastatic hepatocellular carcinomas. Radiation recall dermatitis (RRD) is an acute inflammatory reaction confined to previously irradiated skin that occurs after the administration of certain drugs. RRD after sorafenib treatment is rare; five cases have been reported thus far. We describe a 44-year-old man irradiated for chest wall bone metastasis from hepatocellular carcinoma. Eight days after radiotherapy completion, systemic therapy for metastatic hepatocellular carcinoma was initiated with sorafenib treatment. Eleven days after starting sorafenib, the patient complained of erythematous rash with pruritus in the chest wall, in a location consistent with the previous radiation field. Sorafenib was continued at the same dose, despite the RRD. The skin reaction subsided over the next 2 weeks without any medical intervention.

    We assessed the outcomes of a simplified technique for the percutaneous placement of a hepatic artery port-catheter system for chemotherapy infusion in advanced hepatocellular carcinoma with portal vein invasion. From February 2003 to February 2008, percutaneous hepatic artery port-catheter insertion was performed in 122 patients who had hepatocellular carcinoma with portal vein invasion. The arterial access route was the common femoral artery. The tip of the catheter was wedged into the right gastroepiploic artery without an additional fixation device. A side hole was positioned at the distal common hepatic artery to allow the delivery of chemotherapeutic agents into the hepatic arteries. Coil embolization was performed only to redistribute to the hepatic arteries or to prevent the inadvertent delivery of chemotherapeutic agents into extrahepatic arteries. The port chamber was created at either the supra-inguinal or infra-inguinal region. Technical success was achieved in all patients. Proper positioning of the side hole was checked before each scheduled chemotherapy session by port angiography. Catheter-related complications occurred in 19 patients (16%). Revision was achieved in 15 of 18 patients (83%). This simplified method demonstrates excellent technical feasibility, an acceptable range of complications, and is hence recommended for the management of advanced hepatocellular carcinoma with portal vein thrombosis

    To treated with electrochemotherapy (ECT) a prospective case series of patients with liver cirrhosis and Vp3-Vp4- portal vein tumor thrombus (PVTT) from hepatocellular carcinoma (HCC), in order to evaluate the feasibility, safety and efficacy of this new non thermal ablative technique in those patients. Six patients (5 males and 1 female), aged 61-85 years (mean age, 70 years), four in Child-Pugh A and two in Child-Pugh B class, entered our study series. All patients were studied with three-phase computed tomography (CT), contrast enhanced ultrasound (CEUS) and ultrasound-guided percutaneous biopsy of the thrombus before ECT. All patients underwent ECT treatment (Cliniporator Vitae ® , IGEA SpA, Carpi, Modena, Italy) of Vp3-Vp4 PVTT in a single session. At the end of the procedure a post-treatment biopsy of the thrombus was performed. Scheduled follow-up in all patients entailed: CEUS within 24 h after treatment; triphasic contrast-enhanced CT and CEUS at 3 mo after treatment and every six months thereafter. Post-treatment CEUS showed complete absence of enhancement of the treated thrombus in all cases. Post-treatment biopsy showed apoptosis and necrosis of tumor cells in all cases. The follow-up ranged from 9 to 20 mo (median, 14 mo). In 2 patients, the follow-up CT and CEUS demonstrated complete patency of the treated portal vein. Other 3 patients showed a persistent avascular non-tumoral shrinked thrombus at CEUS and CT during follow-up. No local recurrence was observed at follow-up CT and CEUS in 5/6 patients. One patient was lost to follow-up because of death from gastrointestinal hemorrage 5 wk after ECT. In patients with cirrhosis, ECT seems effective and safe for curative treatment of Vp3-Vp4 PVTT from HCC.

    To investigate hepatocellular carcinoma screening utilisation and factors associated with utilisation among patients prescribed hepatitis B virus anti-viral therapy and at risk of hepatocellular carcinoma. The incidence of hepatocellular carcinoma has increased in Australia over the past three decades with chronic hepatitis B virus infection a major contributor. hepatocellular carcinoma surveillance programs aim to detect cancers early enabling curative treatment options, longer survival and longer times to recurrence. Multi-site cross-sectional survey. An online study questionnaire was administered to eligible participants attending three Sydney tertiary hospitals. Data were grouped into six mutually exclusive hepatocellular carcinoma risk factor categories as per American Association for the Study of Liver Diseases guidelines. All analyses were undertaken in STATA. Logistic regression was used to assess the associations between covariates and screening utilisation. Multivariate models described were assessed using the Hosmer-Lemeshow goodness of fit. Of the 177 participants, 137 (77.4%) self-reported that US had been performed in the last six months. Awareness that screening should be performed and knowing the correct frequency of US screening were independently associated with screening utilisation. Participants who knew that screening should be undertaken were three times more likely to have had pretreatment education or were prescribed hepatitis B virus anti-viral treatment for >4 years. Participants reporting a family history of hepatocellular carcinoma were less likely to know that screening should be undertaken every 6 months. While utilisation of hepatocellular carcinoma surveillance programs was higher in this study than in previous reports, strategies to further improve surveillance remain necessary. Findings from this research form the basis for proposing strategies to improve utilisation of hepatocellular carcinoma screening, inform hepatitis B virus

    Hepatocellular carcinoma (HCC) is one of the most aggressive malignancies in the world whose chemoprevention became increasingly important in HCC treatment. Although the anticancer effects of asparagus constituents have been investigated in several cancers, its effects on hepatocellular carcinoma have not been fully studied. In this study, we investigated the anticancer effects of the deproteinized asparagus polysaccharide on the hepatocellular carcinoma cells using the in vitro and in vivo experimental model. Our data showed that deproteinized asparagus polysaccharide might act as an effective inhibitor on cell growth in vitro and in vivo and exert potent selective cytotoxicity against human hepatocellular carcinoma Hep3B and HepG2 cells. Further study showed that it could potently induce cell apoptosis and G2/M cell cycle arrest in the more sensitive Hep3B and HepG2 cell lines. Moreover, deproteinized asparagus polysaccharide potentiated the effects of mitomycin both in vitro and in vivo. Mechanistic studies revealed that deproteinized asparagus polysaccharide might exert its activity through an apoptosis-associated pathway by modulating the expression of Bax, Bcl-2, and caspase-3. In conclusion, deproteinized asparagus polysaccharide exhibited significant anticancer activity against hepatocellular carcinoma cells and could sensitize the tumoricidal effects of mitomycin, indicating that it is a potential therapeutic agent (or chemosensitizer) for liver cancer therapy.

    Hepatocellular carcinoma often evades effective therapy and recurrences are frequent. Recently, nanosecond pulsed electric field (nsPEF) ablation using pulse power technology has emerged as a local-regional, non-thermal, and non-drug therapy for skin cancers. In the studies reported here we use nsPEFs to ablate murine, rat and human HCCs in vitro and an ectopic murine Hepa 1-6 HCC in vivo. Using pulses with 60 or 300 ns and electric fields as high as 60 kV/cm, murine Hepa 1-6, rat N1S1 and human HepG2 HCC are readily eliminated with changes in caspase-3 activity. Interestingly caspase activities increase in the mouse and human model and decrease in the rat model as electric field strengths are increased. In vivo, while sham treated control mice survived an average of 15 days after injection and before humane euthanasia, Hepa 1-6 tumors were eliminated for longer than 50 days with 3 treatments using one hundred pulses with 100 ns at 55 kV/cm. Survival was 40% in mice treated with 30 ns pulses at 55 kV/cm. This study demonstrates that nsPEF ablation is not limited to effectively treating skin cancers and provides a rationale for treating orthotopic hepatocellular carcinoma in pre-clinical applications and ultimately in clinical trials.

    We report on our experience in terms of eligibility, safety, response and survival for treatment of hepatocellular carcinoma (HCC) with (90)Y microspheres. Secondly, we investigated the urinary excretion of (90)Y following treatment. We retrospectively reviewed all HCC patients referred to our department for (90)Y microsphere treatment. We recorded reasons for not proceeding to actual treatment. In case treatment was performed, we assessed the tolerance (Common Terminology Criteria for Adverse Events v3.0, CTCAE v3.0), the response [modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria] and long-term survival (Kaplan-Meier). The urinary excretion was estimated by 12-h urine collections post-injection for analysis in a gamma counter. Forty-three HCC patients were referred for radioembolization. Fourteen patients were excluded, mainly due to unfavourable (99m)Tc-macroaggregated albumin (MAA) distribution. Twenty-nine patients were treated with (90)Y microspheres (TheraSphere, mean activity 2.17 GBq). In four patients severe clinical adverse events were encountered, however only in one case clearly related to the therapy. Twenty patients were assessable by mRECIST: complete response in 15%, partial response in 35%, stable disease in 30% and progression in 20% were observed. A median survival of 12.3 months (95% confidence interval 9.4-15.2) was estimated. Concerning the substudy on urinary excretion, only 0.0025% of the administered activity was excreted in the urine within the first 12 h following TheraSphere. Following a strict workup before admitting patients to radioembolization with TheraSphere, we found good clinical tolerance in the vast majority of patients. Radiological response assessment yielded an overall response rate of 50%, when evaluated early following treatment. Urine analysis showed consistently only low activities of (90)Y excreted in the urine.

    To determine the value of a raw data-based metal artifact reduction (SEMAR) algorithm for image quality improvement in abdominal CT for patients with small metal implants. Fifty-eight patients with small metal implants (3-15 mm in size) who underwent treatment for hepatocellular carcinoma were imaged with CT. CT data were reconstructed by filtered back projection with and without SEMAR algorithm in axial and coronal planes. To evaluate metal artefact reduction, mean CT number (HU and SD) and artefact index (AI) values within the liver were calculated. Two readers independently evaluated image quality of the liver and pancreas and visualization of vasculature using a 5-point visual score. HU and AI values and image quality on images with and without SEMAR were compared using the paired Student's t-test and Wilcoxon signed rank test. Interobserver agreement was evaluated using linear-weighted κ test. Mean HU and AI on images with SEMAR was significantly lower than those without SEMAR (P small metal implants by reducing metallic artefacts. • SEMAR algorithm significantly reduces metallic artefacts from small implants in abdominal CT. • SEMAR can improve image quality of the liver in dynamic CECT. • Confidence visualization of hepatic vascular anatomies can also be improved by SEMAR.

  12. Combination of the oral histone deacetylase inhibitor resminostat with oncolytic measles vaccine virus as a new option for epi-virotherapeutic treatment of hepatocellular carcinoma

    Directory of Open Access Journals (Sweden)

    Benjamin Ruf

    Full Text Available Epigenetic therapies such as histone deacetylase inhibitors (HDACi not only have the capability to decrease tumor cell proliferation and to induce tumor cell death but also to silence antiviral response genes. Here, we investigated whether the combination of an oncolytic measles vaccine virus (MeV with the novel oral HDACi resminostat (Res, being in clinical testing in patients with hepatocellular carcinoma (HCC, results in an enhanced efficacy of this epi-virotherapeutic approach compared to any of the two corresponding monotherapies. When testing a panel of human hepatoma cell lines, we found (i a significantly improved rate of primary infections when using oncolytic MeV under concurrent treatment with resminostat, (ii a boosted cytotoxic effect of the epi-virotherapeutic combination (Res + MeV with enhanced induction of apoptosis, and, quite importantly, (iii an absence of any resminostat-induced impairment of MeV replication and spread. Beyond that, we could also show that (iv resminostat, after hepatoma cell stimulation with exogenous human interferon (IFN-β, is able to prevent the induction of IFN-stimulated genes, such as IFIT-1. This finding outlines the possible impact of resminostat on cellular innate immunity, being instrumental in overcoming resistances to MeV-mediated viral oncolysis. Thus, our results support the onset of epi-virotherapeutic clinical trials in patients exhibiting advanced stages of HCC.

Liver and pancreas image qualities and visualizations of vasculature were significantly improved on CT with SEMAR (P < 0.0001) with substantial or almost perfect agreement (0.62 ≤ κ ≤ 0.83). SEMAR can improve image quality in abdominal CT in patients with small metal implants by reducing metallic artefacts. (orig.)

    Hepatocellular carcinoma (HCC) risk-scores may predict HCC in Asian entecavir (ETV)-treated patients. We aimed to study risk factors and performance of risk scores during ETV treatment in an ethnically diverse Western population. We studied all HBV monoinfected patients treated with ETV from 11 European referral centres within the VIRGIL Network. A total of 744 patients were included; 42% Caucasian, 29% Asian, 19% other, 10% unknown. At baseline, 164 patients (22%) had cirrhosis. During a median follow-up of 167 (IQR 82-212) weeks, 14 patients developed HCC of whom nine (64%) had cirrhosis at baseline. The 5-year cumulative incidence rate of HCC was 2.1% for non-cirrhotic and 10.9% for cirrhotic patients (peliminate the risk of HCC. Discriminatory performance of HCC risk scores was limited, particularly in Caucasians, at baseline and during therapy. Published by the BMJ Publishing Group Limited.

Liver and pancreas image qualities and visualizations of vasculature were significantly improved on CT with SEMAR (P < 0.0001) with substantial or almost perfect agreement (0.62 ≤ κ ≤ 0.83). SEMAR can improve image quality in abdominal CT in patients with small metal implants by reducing metallic artefacts. (orig.)

    Full Text Available The present therapy for primary hepatocellular carcinoma (HCC consists of surgery as well as local radiotherapy and chemotherapy. However, the majority of patients are susceptible to recurrence after comprehensive treatment, and the overall treatment outcome is not ideal due to the lack of effective drugs and strategies. Increasing evidence has demonstrated that the immune system is closely related to the development, progression, metastasis, and recurrence of HCC. Thus, immune therapy, especially cellular immunotherapy, could regulate immune function and induce specific antitumor immunity to achieve the goal of controlling HCC and reducing its recurrence and metastasis, which has become an essential part in the comprehensive treatment of HCC. The findings in preclinical and clinical studies on cellular immunotherapy for HCC data are reviewed, and the current problems are discussed.

    Fibrolamellar hepatocellular carcinoma is a rare primary malignant liver tumor, significantly different from generic hepatocellular carcinoma with distinct demographics, risk factors, imaging features, histopathology and prognosis. Unlike conventional hepatocellular carcinoma, it presents in young individuals with no preexisting hepatitis or cirrhosis and does not cause elevation of serum alpha feto proteins in most cases. This paper presents a case report of this rare tumor in a young female with an unusual clinical manifestation of obstructive jaundice (which has not been reported so far) along with a review of its imaging and pathological features, with treatment options. Fibrolamellar HCC is a rare variant of classic HCC with different epidemiology, risk factors, clinical manifestations, radiological, pathological and prognostic features. Therefore, it is important to be familiar with the entity for its early diagnosis and management

    Overexpression of Cullin7 is associated with some types of malignancies. However, the part of Cullin7 in hepatocellular carcinoma remains unclear. The aim of this study was to investigate the role of Cullin7 in pathogenesis and the progression of hepatocellular carcinoma. In the present study, the expression of Cullin7 in hepatocellular carcinoma cell lines and five surgical hepatocellular carcinoma specimens was detected with quantitative reverse transcription PCR and western blotting. In addition, the protein expression of Cullin7 was examined in 162 cases of archived hepatocellular carcinoma using immunohistochemistry. We found elevated expression of both mRNA and protein levels of Cullin7 in hepatocellular carcinoma cell lines, and Cullin7 protein was significantly upregulated in hepatocellular carcinoma compared with paired normal hepatic tissues. The immunohistochemistry analysis revealed that overexpression of Cullin7 occurred in 69.1% of hepatocellular carcinoma samples, which was a significantly higher rate than that in adjacent normal hepatic tissue (P hepatocellular carcinoma HepG2 cells, we revealed that Cullin7 could significantly enhance cell proliferation, growth, migration and invasion. Conversely, knocking down Cullin7 expression with short hairpin RNAi in hepatocellular carcinoma HepG2 cells inhibited cell proliferation, growth, migration and invasion. Our studies provide evidence that overexpression of Cullin7 plays an important role in the pathogenesis and progression of hepatocellular carcinoma and may be a valuable marker for hepatocellular carcinoma management.

    Circulating hepatocellular carcinoma cells may be detected by reverse transcription-polymerase chain reaction. We investigated the relationship between circulating hepatocellular carcinoma cells and hepatoma patient survival after different managements and survival periods. Peripheral vein blood (5 ml) samples were obtained from 113 patients with hepatocellular carcinoma and from 33 control subjects (9 with liver cirrhosis after hepatitis B, 14 with chronic hepatitis B, 10 healthy individuals) between January 1, 2009, and December 31, 2013. To detect circulating hepatocellular carcinoma cells in peripheral blood, alpha-fetoprotein messenger RNA was amplified from total RNA extracted from whole blood by reverse transcription-polymerase chain reaction. Alpha-fetoprotein messenger RNA was detected in 59 blood samples from the hepatocellular carcinoma patients (59/113, 52.2%). In contrast, there were no clinical control subjects whose samples showed detectable alpha-fetoprotein messenger RNA. The presence of alpha-fetoprotein messenger RNA in blood seemed to be correlated with the stage (by TNM classification) of hepatocellular carcinoma, serum alpha-fetoprotein value, and the presence of intrahepatic metastasis, portal vein thrombosis, tumor diameter and/or distant metastasis. In addition, alpha-fetoprotein messenger RNA was detected in the blood of 25 patients showing distant metastasis at extrahepatic organs (100%), in contrast to 32 of 88 cases without metastasis (36.4%). All the patients with hepatocellular carcinoma were followed. Seventeen patients with resection of a T 2 stage hepatocellular carcinoma had a survival of 3.2 years after surgical management, 38 cases with resection of a T3 stage hepatocellular carcinoma had a 1.3-year survival, and only 37 cases with T4 stage disease after different treatments except surgery survived for 0.6 years (P <0.01). The presence of alpha-fetoprotein messenger RNA in peripheral blood may be an indicator of circulating

    We retrospectively evaluated the characteristic computed tomographic(CT) findings in nine patients with exohepatic hepatocellular carcinoma(HCC) pathologically prove by surgery(n=2) or percutaneous needle biopsy(n=7). The CT findings of exphepatic HCC were correlated with clinical findings and compared with those of usual HCC. Lesions were in the left lobe(n=7) and right lobe(n=2) of the liver. All lesions showed a well-marginated hypodense mass with capsular enhancement on enhanced CT scan. The patterns of capsular enhancement were complete in five and partial in four case. The portal vein thrombosis was seen only in one case. There was no difference between exohepatic HCC and usual HCC in clinical findings such as increased {alpha}-fetoprotein({alpha}-FP), positive hepatitis B surface antigen(HBsAg), and underlying liver cirrhosis. In conclusion, the CT findings of exohepatic HCC were a well-defined hyperdense mass with complete or partial capsular enhancement and these findings may be useful in differentiation from the tumors of adjacent organs.

    Purpose: To retrospectively evaluate the safety and effectiveness of repeated proton beam therapy for newly developed or recurrent hepatocellular carcinoma (HCC). Methods and Materials: From June 1989 through July 2000, 225 patients with HCC underwent their first course of proton beam therapy at University of Tsukuba. Of them, 27 with 68 lesions who had undergone two or more courses were retrospectively reviewed in this study. Median interval between the first and second course was 24.5 months (range 3.3-79.8 months). Median total dose of 72 Gy in 16 fractions and 66 Gy in 16 fractions were given for the first course and the rest of the courses, respectively. Results: The 5-year survival rate and median survival period from the beginning of the first course for the 27 patients were 55.6% and 62.2 months, respectively. Five-year local control rate for the 68 lesions was 87.8%. Of the patients, 1 with Child-Pugh class B and another with class C before the last course suffered from acute hepatic failure. Conclusions: Repeated proton beam therapy for HCC is safe when the patient has a target in the peripheral region of the liver and liver function is Child-Pugh class A

    Current treatment options for hepatocellular carcinoma (HCC) are often limited by the presence of underlying liver disease. In patients with liver cirrhosis, surgery, chemotherapy, and radiation therapy all carry a high risk of hepatic complications, ranging from ascites to fulminant liver failure. For patients receiving radiation therapy, cirrhosis dramatically reduces the already limited radiation tolerance of the liver and represents the most important clinical risk factor for the development of radiation-induced liver disease. Although improvements in conformal radiation delivery techniques have improved our ability to safely irradiate confined areas of the liver to increasingly higher doses with excellent local disease control, patients with moderate-to-severe liver cirrhosis continue to face a shortage of treatment options for HCC. In recent years, evidence has emerged supporting the use of bone marrow–derived stromal cells (BMSCs) as a promising treatment for liver cirrhosis, with several clinical studies demonstrating sustained improvement in clinical parameters of liver function after autologous BMSC infusion. Three predominant populations of BMSCs, namely hematopoietic stem cells, mesenchymal stem cells, and endothelial progenitor cells, seem to have therapeutic potential in liver injury and cirrhosis. Preclinical studies of BMSC transplantation have identified a range of mechanisms through which these cells mediate their therapeutic effects, including hepatocyte transdifferentiation and fusion, paracrine stimulation of hepatocyte proliferation, inhibition of activated hepatic stellate cells, enhancement of fibrolytic matrix metalloproteinase activity, and neovascularization of regenerating liver. By bolstering liver function in patients with underlying Child's B or C cirrhosis, autologous BMSC infusion holds great promise as a therapy to improve the safety, efficacy, and utility of surgery, chemotherapy, and hepatic radiation therapy in the

    Gene regulation of many key cell-cycle players in S-, G(2) phase, and mitosis results from transcriptional repression in their respective promoter regions during the G(0) and G(1) phases of cell cycle. Within these promoter regions are phylogenetically conserved sequences known as the cell-cycle-dependent element (CDE) and cell-cycle genes homology regions (CHR) sites. Thus, we hypothesize that transcriptional regulation of cell-cycle regulation via the CDE/CHR region together with liver-specific apolipoprotein E (apoE)-hAAT promoter could bring about a selective transgene expression in proliferating human hepatocellular carcinoma. We show that the newly generated vector AH-6CC-L2C could mediate hepatocyte-targeted luciferase gene expression in tumor cells and freshly isolated short-term hepatocellular carcinoma cultures from patient biopsy. In contrast, normal murine and human hepatocytes infected with AH-6CC-L2C expressed minimal or low luciferase activities. In the presence of prodrug 5-fluorocytosine (5-FC), AH-6CC-L2C effectively suppressed the growth of orthotopic hepatocellular carcinoma patient-derived xenograft mouse model via the expression of yeast cytosine deaminase (yCD) that converts 5-FC to anticancer metabolite 5-fluoruracil. More importantly, we show that combination treatment of AH-6CC-L2C with an EZH2 inhibitor, DZNep, that targets EpCAM-positive hepatocellular carcinoma, can bring about a greater therapeutic efficacy compared with a single treatment of virus or inhibitor. Our study showed that targeting proliferating human hepatocellular carcinoma cells through the transcriptional control of therapeutic gene could represent a feasible approach against hepatocellular carcinoma.

    Full Text Available Hepatocellular carcinoma (HCC is the second cause of cancer-related death in the world and is the main cause of death in cirrhotic patients. Unfortunately, the incidence of HCC has grown significantly in the last decade. Curative treatments such as surgery, liver transplantation or percutaneous ablation can only be applied in less than 30% of cases. The multikinase inhibitor sorafenib is the first line therapy for advanced HCC. Regorafenib is the standard of care for second-line patients. However, novel and more specific potent therapeutic approaches for advanced HCC are still needed. The liver constitutes a unique immunological microenvironment, although anti-tumor immunity seems to be feasible with the use of checkpoint inhibitors such as nivolumab. Efficacy may be further increased by combining checkpoint inhibitors or by applying loco-regional treatments. The success of immune checkpoint blockade has renewed interest in immunotherapy in HCC

    Full Text Available Use of herbal medicine in the treatment of liver cancer has a long tradition. The compounds derived from the herb and herbal composites are of considerable interest among oncologists. In the past, certain herbal compounds and herbal composite formulas have been studied through in vitro and in vivo as an anti-hepatocellular carcinoma (HCC agent, enhancing our knowledge about their biologic functions and targets. However there is a significant distinction between the herbal medicine and the herbal production even though both are the plant-based remedies used in the practice. In this article, for the sake of clarity, the effective herbal compounds and herbal composite formulas against HCC are discussed, with emphasizing the basic conceptions of herbal medicine in order to have a better understanding of the prevention and treatment of HCC by herbal active compounds and herbal composite formulas.

Radiologic database was searched for the patients referred to perform TACE and CBCT-RFA for small caudate HCCs (≤2 cm) between February 2009 and February 2014. A total of 14 patients (12 men and 2 women, mean age; 61.3 years) were included. Percutaneous ultrasonography-guided RFA (pUS-RFA) and surgery were infeasible due to poor conspicuity, inconspicuity or no safe electrode pathway, and poor hepatic reserve. Procedural success (completion of both TACE and CBCT-RFA), technique efficacy (absence of tumor enhancement at 1 month after treatment), and complication were evaluated. Treatment results including local tumor progression (LTP), intrahepatic distant recurrence (IDR), overall survival (OS), and progression-free survival (PFS) were analyzed.ResultsProcedural success and technique efficacy rates were 78.6 % (11/14) and 90.9 % (10/11), respectively. Average follow-up period was 45.3 months (range, 13.4–64.6 months). The 1-, 3-, and 5-year LTP probabilities were 0, 12.5, and 12.5 %, respectively. IDR occurred in seven patients (63.6 %, 7/11). The 1-, 3-, and 5-year PFS probabilities were 81.8, 51.9, and 26 %, respectively. The 1-, 3-, and 5-year OS probabilities were 100, 80.8, and 80.8 %, respectively.ConclusionCombination of TACE and CBCT-RFA seems feasible for small HCC in the caudate lobe not amenable to pUS-RFA and effective in local tumor control.

    Transcatheter arterial chemoembolization (TACE) offers a survival benefit to patients with intermediate hepatocellular carcinoma (HCC). A widely accepted TACE regimen includes administration of doxorubicin-oil emulsion followed by gelatine sponge-conventional TACE. Recently, a drug-eluting bead (DC Bead) has been developed to enhance tumor drug delivery and reduce systemic availability. This randomized trial compares conventional TACE (cTACE) with TACE with DC Bead for the treatment of cirrhotic patients with HCC. Two hundred twelve patients with Child-Pugh A/B cirrhosis and large and/or multinodular, unresectable, N0, M0 HCCs were randomized to receive TACE with DC Bead loaded with doxorubicin or cTACE with doxorubicin. Randomization was stratified according to Child-Pugh status (A/B), performance status (ECOG 0/1), bilobar disease (yes/no), and prior curative treatment (yes/no). The primary endpoint was tumor response (EASL) at 6 months following independent, blinded review of MRI studies. The drug-eluting bead group showed higher rates of complete response, objective response, and disease control compared with the cTACE group (27% vs. 22%, 52% vs. 44%, and 63% vs. 52%, respectively). The hypothesis of superiority was not met (one-sided P = 0.11). However, patients with Child-Pugh B, ECOG 1, bilobar disease, and recurrent disease showed a significant increase in objective response (P = 0.038) compared to cTACE. DC Bead was associated with improved tolerability, with a significant reduction in serious liver toxicity (P < 0.001) and a significantly lower rate of doxorubicin-related side effects (P = 0.0001). TACE with DC Bead and doxorubicin is safe and effective in the treatment of HCC and offers a benefit to patients with more advanced disease.

    To use magnetic resonance (MR) imaging and clinical patient data to create an artificial intelligence (AI) framework for the prediction of therapeutic outcomes of transarterial chemoembolization by applying machine learning (ML) techniques. This study included 36 patients with hepatocellular carcinoma (HCC) treated with transarterial chemoembolization. The cohort (age 62 ± 8.9 years; 31 men; 13 white; 24 Eastern Cooperative Oncology Group performance status 0, 10 status 1, 2 status 2; 31 Child-Pugh stage A, 4 stage B, 1 stage C; 1 Barcelona Clinic Liver Cancer stage 0, 12 stage A, 10 stage B, 13 stage C; tumor size 5.2 ± 3.0 cm; number of tumors 2.6 ± 1.1; and 30 conventional transarterial chemoembolization, 6 with drug-eluting embolic agents). MR imaging was obtained before and 1 month after transarterial chemoembolization. Image-based tumor response to transarterial chemoembolization was assessed with the use of the 3D quantitative European Association for the Study of the Liver (qEASL) criterion. Clinical information, baseline imaging, and therapeutic features were used to train logistic regression (LR) and random forest (RF) models to predict patients as treatment responders or nonresponders under the qEASL response criterion. The performance of each model was validated using leave-one-out cross-validation. Both LR and RF models predicted transarterial chemoembolization treatment response with an overall accuracy of 78% (sensitivity 62.5%, specificity 82.1%, positive predictive value 50.0%, negative predictive value 88.5%). The strongest predictors of treatment response included a clinical variable (presence of cirrhosis) and an imaging variable (relative tumor signal intensity >27.0). Transarterial chemoembolization outcomes in patients with HCC may be predicted before procedures by combining clinical patient data and baseline MR imaging with the use of AI and ML techniques.

    Full Text Available We report a unique case of combined primary neuroendocrine carcinoma (NEC and hepatocellular carcinoma (HCC of the liver in a 65-year-old male patient. The patient underwent segmental resection of the liver and regional lymph node dissection for a tumor mass that measured 7.5 cm in diameter in the right lobe, with regional lymphadenopathy. Histologically, the hepatic tumor was composed of predominantly small-cell NEC, but admixed with a small island of moderately differentiated HCC. We speculate that the NEC originated from a poorly differentiated tumor clone of an HCC that underwent neuroendocrine differentiation, and that this tumor was now at the end stage of the transitional period from HCC to NEC, based on the small amount of disappearing HCC. Ki-67 and p53 expression were higher in the NEC than in the HCC, and the lymph nodes showed only metastatic NEC. Therefore, this kind of tumor had a more aggressive clinical course in accordance with being an NEC rather than a conventional HCC. Three months after operation, the patient had multiple recurrent tumor nodules within the liver, spreading the metastasis to the adrenal glands and para-aortic lymph nodes. The patient died 1 year after operation.

    Intra-arterial injection of Yttrium-90 glass microspheres ((90)Y- microS; TheraSphere, MDS Nordion, Ottawa, Canada) is indicated for treatment of unresectable hepatocellular carcinoma (HCC) in the presence of acceptable liver function. This study presents hepatic toxicity results after unilobar and bilobar intra-arterial administration of (90)Y- microS in patients with unresectable HCC who had known portal vein thrombosis (PVT) without evidence of cavernous transformation. Fifteen patients with unresectable HCC and PVT of one or both first order and related segmental portal venous branches received a total of 29 infusions of (90)Y- microS for treatment of HCC. All patients had pretreatment evaluation including: computed tomography (CT) imaging, alpha-fetoprotein (AFP) levels, liver function tests, technetium-99m macroaggregated albumin ((99)Tc-MAA) scan for evaluation of lung and visceral shunting, and angiography with visualization into the portal venous phase. (90)Y- micro S dose was based on lobar hepatic volume with adjustment for lung shunt activity. Liver toxicity was assessed by serum total bilirubin graded for severity according to the NIH NCI Clinical Toxicity Criteria (CTC version 2.0). Other adverse events were reported according to the standards established by the Society of Interventional Radiology. There were no procedural complications with delivery of (90)Y- microS, and treatment was well tolerated by all patients. Increased post-treatment bilirubin levels were observed across all treatments in five patients, four of whom had CT or AFP evidence of intrahepatic disease progression. After initial treatment, two patients developed bilirubin toxicity (grades 1 and 2); one patient demonstrated an increment in bilirubin toxicity grade (grade 1 to grade 3) and one patient had an improvement in grade after initial treatment. There were no new treatment-related toxicities in nine patients after a second treatment. (90)Y- microS treatment was well tolerated

    Hepatocellular carcinoma is the most common primary malignant tumor of liver. Metastasis of hepatocellular carcinoma occurs in various organs, but metastasis to the ovary is extremely rare. We report MRI finding of metastatic hepatocellular carcinoma of the ovary in a 37-year-old woman who was treated hepatocellular carcinoma transarterial chemoembolization and radiofrequency ablation a year ago. Pelvic MRI revealed a mass in pelvic cavity with heterogeneous signal intensity and centripetal enhancement. Surgical excision and pathologic examination confirmed metastatic hepatocellular carcinoma in the ovary.

    The incidence of hepatocellular carcinoma (HCC), once thought to be a rare tumor in North America, has rapidly increased in recent years in the United States. Current treatment modalities to halt the progression of this disease are only marginally effective. The mainstay treatment is liver transplantation, which is often confronted with donor shortage. Invasion, metastasis and recurrence contribute to the high mortality rate of this disease. Matrix metalloproteinases (MMPs) that degrade the extracellular matrix (ECM) have been associated with the progression, invasion and metastasis of the disease. We have developed strategies to strengthen the ECM collagen and inhibit MMPs through micronutrients such as lysine, proline and ascorbic acid. Addition of epigallocatechin gallate or green tea extract to these micronutrients synergistically enhanced anti-carcinogenic activity in HepG2 cells. Addition of certain other micronutrients, such as N-acetylcysteine, selenium, copper and zinc (NM) synergistically enhanced the anticancer activity of the mixture in a model of hepatocellular carcinoma using HepG2 cells. In vitro studies using HepG2 demonstrated that NM was very effective in inhibiting cell proliferation (by MTT assay), MMPs secretion (by gelatinase zymography), cell invasion (through Matrigel) and induction of apoptosis (by live green caspase). In addition, NM was shown to down-regulate urokinase plasminogen activator (by fibrin zymography) and up-regulate tissue inhibitors of metalloproteinases (by reverse zymography) in another HCC cell line, SK-Hep-1. MMP-2 and MMP-9 activities were further modulated by phorbol 12-myristate 13-acetate (PMA) induction and inhibited by NM. In previous studies, NM inhibited Sk-Hep-1 xenografts in nude mice and also inhibited hepatic metastasis of B16FO melanoma cells. Our results suggest that NM is an excellent candidate for therapeutic use in the treatment HCC by inhibiting critical parameters in cancer development and progression

    Purpose: This study was designed to evaluate the usefulness of percutaneous ethanol injection (PEI) with a multipronged needle for the treatment of large hepatocellular carcinoma (HCC). An experimental animal study and a clinical investigation were performed. Methods: In the experimental study, 20 ml of 99.5% ethanol was injected into porcine liver in vivo with a multipronged needle (n = 5) or a straight needle (n = 5), and the volumes of coagulation necrosis were compared. In the clinical investigation, PEI was performed in 17 patients (10 men, 7 women; mean age 73.4 ± 6.7 years) with single, large HCC (mean tumor diameter, 47.2 ± 11.5 mm; range, 32–70 mm) by using a multipronged needle. Fifteen of 17 patients received transarterial chemoembolization (TACE) before PEI. Results: The volume of coagulation in porcine liver in vivo was significantly increased with the multipronged needle compared with the straight needle (longest perpendicular diameters, 34.2 ± 3.6 mm × 30.2 ± 3.6 mm vs. 22.6 ± 2.5 mm × 19 ± 2.2 mm, respectively; P < 0.05). In the clinical trial, initial complete response (CR) of the tumor was achieved in 17 of 17 patients, 7 of whom required two PEI sessions. During the follow-up, local recurrence was detected in 4 of 17 patients at 3–19 months after the procedure, for a rate of sustained local CR of 76%. No major complication occurred. Conclusions: Use of a multipronged needle substantially increases the volume of coagulation in vivo with respect to the conventional PEI technique. Combined TACE and PEI with multipronged needles is a safe and effective option for percutaneous treatment of single, large HCC.

    Patients with early-stage hepatocellular carcinoma (HCC) are potential candidates for curative treatments such as radiofrequency ablation (RFA), surgical resection (SR), or liver transplantation (LT), which have demonstrated a significant survival benefit. We aimed to estimate the cost-effectiveness of curative and combination treatment strategies among patients diagnosed with HCC during 2002-2010. This study used Ontario Cancer Registry-linked administrative data to estimate effectiveness and costs (2013 USD) of the treatment strategies from the healthcare payer's perspective. Multiple imputation by logistic regression was used to handle missing data. A net benefit regression approach of baseline important covariates and propensity score adjustment were used to calculate incremental net benefit to generate incremental cost-effectiveness ratio (ICER) and uncertainty measures. Among 2,222 patients diagnosed with HCC, 10.5%, 14.1%, and 10.3% received RFA, SR, and LT monotherapy, respectively; 0.5-3.1% dual treatments; and 0.5% triple treatments. Compared with no treatment (53.2%), transarterial chemoembolization (TACE) + RFA (average $2,465, 95% CI: -$20,000-$36,600/quality-adjusted life years [QALY]) or RFA monotherapy ($15,553, 95% CI: $3,500-$28,500/QALY) appears to be the most cost-effective modality with lowest ICER value. The cost-effectiveness acceptability curve showed that if the relevant threshold was $50,000/QALY, RFA monotherapy and TACE+ RFA would have a cost-effectiveness probability of 100%. Strategies using LT delivered the most additional QALYs and became cost-effective at a threshold of $77,000/QALY. Our findings found that TACE+ RFA dual treatment or RFA monotherapy appears to be the most cost-effective curative treatment for patients with potential early stage of HCC in Ontario. These findings highlight the importance of identifying and measuring differential benefits, costs, and cost-effectiveness of alternative HCC curative treatments in

    Indian data on epidemiology of HCC is not available. Cancer is not a reportable disease in India and the cancer registries in India are mostly urban. National cancer registry program of the Indian Council of Medical Research (ICMR) has been recently expanded to include 21 population based and 6 hospital based cancer registries. The last published registry data by ICMR available in the cancer registry website (www.ncrpindia.org) was in 2008 which provides information on various cancers from 2006 to 2008. The other source of information was the report published by International Agency for Research on Cancer (WHO). According to these available data the age adjusted incidence rate of hepatocellular carcinoma (HCC) in India for men ranges from 0.7 to 7.5 and for women 0.2 to 2.2 per 100,000 population per year. The male:female ratio for HCC in India is 4:1. The age of presentation varies from 40 to 70 years. According to a study conducted by verbal autopsy in 1.1 million homes representing the whole country, the age standardized mortality rate for HCC in India for men is 6.8/100,000 and for women is 5.1/100,000. According to another study the incidence of HCC in cirrhotics in India is 1.6% per year. The unpublished data from various tertiary care centers suggest that the incidence of HCC is increasing in India. There is a need for a multi-centric HCC registry under the aegis of INASL.

    Dichlorodiphenyltrichloroethane (p,p’-DDT), an organochlorine pesticide known to have deleterious health effects in humans, has been linked to hepatocellular carcinoma (HCC) in rodents. A recent study has reported that p,p’-DDT and its most persistent metabolite, dichlorodiphenyldichloroethylene (p,p’-DDE), may also be associated with HCC in humans. To examine whether there is an association between p,p’-DDT and/or p,p’-DDE in a population at high-risk of developing HCC. A nested case-control study was conducted within the 83,794 person Haimen City Cohort in China. Sera and questionnaire data were collected from all participants between 1992 and 1993. The current study included 473 persons who developed HCC and 492 who did not, frequency matched on sex, age and area of residence. p,p’-DDT and p,p’-DDE levels were determined by mass spectrometry. Hepatitis B viral infection status (based on hepatitis B virus surface antigen; HBsAg) was also determined. Adjusting for age, sex, area of residence, HBsAg, family history of HCC, history of acute hepatitis, smoking, alcohol, occupation (farmers) and levels of p,p’-DDT or p,p’-DDE, odds ratios (OR) and 95% confidence intervals (CI) were calculated via unconditional logistic regression, p,p’-DDT and/or p,p’-DDE serum levels were significantly associated with sex, area of residence, occupation, alcohol consumption and cigarette smoking. Overall, the highest quintile of p,p’-DDT was associated with an increased risk of HCC, OR= 2.96 95% CI; 1.19–7.40. There were no statistically significant associations with p,p’-DDE. Overall, these results suggest that recent exposure to p,p’-DDT may increase risk of HCC. PMID:22290210

    Purpose: We report our preliminary experience of combining sunitinib and helical tomotherapy in patients with advanced HCC. Methods and Materials: Records of patients with advanced hepatocellular carcinoma (HCC) treated with helical tomotherapy and sunitinib after radiation therapy (RT) from March 2007 to August 2008 were retrospectively reviewed. We report acute toxicities, radiologic response, serial α-fetoprotein (AFP) kinetics, and survival. Results: Of 23 evaluable patients, 60% had ≥2 hepatic lesions, extrahepatic disease was present in 5 (21.7%), and all received 2 tablets (25 mg) of sunitinib at least 1 week before, during, and 2 weeks after RT. Thirteen patients continued maintenance sunitinib after RT until disease progression. Hypofractionated RT with a median target dose of 52.5 Gy/15 fractions was delivered. An objective response was achieved in 74% of patients. The 1-year survival rate was 70%, with median survival of 16 months. Multivariate analysis showed that maintenance sunitinib was the most significant factor for survival. The time to progression was 10 months in the maintenance group compared with 4 months in the control group. Eighteen out of 21 patients with elevated AFP (85.7%) had ≥50% decline of AFP within 2 months after RT. There were three episodes of upper gastrointestinal bleeding and one episode of pancreatitis; 10 patients had ≥Grade 2 elevation of liver enzymes, and 15 had ≥Grade 2 thrombocytopenia. Conclusions: These preliminary results suggest that sunitinib and helical tomotherapy yield high Response Evaluation Criteria in Solid Tumors (RECIST) and AFP response rates in advanced HCC with an acceptable safety profile. Maintenance sunitinib after RT potentially prolongs survival. A randomized trial is warranted.

    Hemodynamic characteristics were studied by using in vivo vascular imaging techniques in 17 resected early stage hepatocellular carcinoma (e-HCC) by comparing them with 49 resected advanced HCCs (ad-HCC) less than 3 cm in diameter. In this study, e-HCC was defined as the nodule being uniformly composed of well-differentiated HCC or adenomatous hyperplastic nodule containing well-differentiated HCC foci within the nodule. In vivo vascular imaging techniques are as follows; US angiography with intraarterial CO 2 microbubbles were performed to assess the tumor arterial vascularity, and CT during arterial portography (CTAP) was performed to assess the portal perfusion within the nodule. Of 17 e-HCC nodules 5 were hypervascular, 5 were isovascular, 4 were hypovascular, and 3 were vascular spot in hypovascular pattern in contrast to 49 ad-HCC nodules, 43 of which were hypervascular and 6 were isovascular. Of 14 e-HCCs, 9 nodules showed perfusion defect and 5 did not on CTAP, whereas all 37 ad-HCCs on which CTAP was performed, showed perfusion defect. Forty-one percent (7/17) of e-HCC showed fatty metamorphosis in contrast to 8% (4/49) of ad-HCC. In conclusion, hemodynamic characteristics of e-HCC are summarized as follows. (1) Arterial tumor neovascularization is relatively low. (2) Portal perfusion is present in some of e-HCC cases. (3) Hypoperfusion state both from arterial and portal supply is present in some of e-HCC cases. (4) Vascular spot in hypovascular pattern is characteristic arterial pattern in AH containing HCC foci. (5) Fatty metamorphosis may be related with hypoperfusion state of the nodule in e-HCC. (author)

    Hepatocellular carcinoma (HCC) is a primary liver malignancy, and is now the six most common in between malignancies. Early diagnosis of HCC with prompt treatment increases the opportunity of patients to survive. With the advances in understanding the molecular biology of HCC, new therapeutic strategies to treat HCC have emerged. There is a growing consensus that vitamins are important for the control of various cancers. Biochemical evidence clearly indicates that HCC cells are responsive to the inhibitory effect of vitamin D, vitamin D analogues and vitamin K. In this review, we summarize the mechanisms used by vitamin D and K to influence the development of HCC and the latest development of vitamin analogues for potential HCC therapy.

    2011-12-01

    Full Text Available Hepatocellular carcinoma represents one of the most common malignancies worldwide with a rising incidence in western countries. Chronic inflammation is recognised as a threat factor for cancer progression. Cyclooxygenase-2 is the major mediator of inflammation. Various studies on Cox-2 suggest its possible association with HCC differentiation. Sufficient genetic and pharmacologic evidences implicate its crucial role in neoplasia and it is also now clear that Cox-2 plays a crucial role in tumor progression. Cox-2 overexpression is associated with maintaining tumor microenvironment and has crucial implication for angiogenesis. Cox-2 operates in multifactorial fashion. Cox-2 selective inhibition has been reported as a successful tool in suppressing angiogenesis and metastasis. The pharmacological suppression of Cox-2 represents a bright future as a therapeutic tool for treatment of various malignancies. This review is an attempt to discuss the critical issue of overexpression of Cox-2 and its role in the development of HCC in particular and cancer in general.

    Transcatheter arterial chemoembolization (TACE) is one of the most commonly used therapeutic procedures for primary hepatocellular carcinoma (HCC). As an important and easily-available embolic agent, gelatin sponge (Gelfoam) particles have been constantly and widely employed in clinical practice. Various types of embolic agents have been continuously developed and effectively used in TACE for liver cancers. For recent years, great progress has been made in the clinical use of gelatin sponge particles, as the most traditional embolic agent, in the interventional therapeutic field for HCC. This article aims to make a comprehensive review about gelatin sponge. (authors)

    For assessment of the value of delayed hepatobiliary imaging with technetium 99m (/sup 99m/Tc)-(Sn)-N-pyridoxyl-5-methyltryptophan (/sup 99m/Tc-PMT) for specific diagnosis of hepatocellular carcinoma, 88 patients with various malignant and benign liver diseases (49 with hepatocellular carcinoma, 4 with cholangiocellular carcinoma, 10 with metastatic liver carcinoma, 2 with liver cysts, 2 with liver hemangioma, 1 with liver abscess, 2 with intrahepatic lithiasis, 12 with liver cirrhosis, and 6 with chronic hepatitis) were studied. In 20 (41%) of the 49 patients with hepatocellular carcinoma, greater uptake of /sup 99m/Tc-PMT by the tumor than by the surrounding liver tissue was seen in delayed hepatobiliary images, whereas in eight patients (16%), equilibrated uptake was seen. No increased uptake of the radioisotope by hepatic lesions was seen in 21 patients with localized liver diseases other than hepatoma. Moreover, in 18 patients with diffuse liver diseases, no focal accumulation of the radioisotope was seen in delayed /sup 99m/Tc-PMT images. In addition, of 28 patients with hepatocellular carcinoma in whom the serum alpha-fetoprotein level showed little or no increase, 12 showed increased uptake of /sup 99m/Tc-PMT by the tumor. In assessing delayed /sup 99m/Tc-PMT images, however, it was necessary to consider following complications: accumulation of tracer in obstructed and dilated biliary trees; retention of radioactivity in nonneoplastic liver tissues; difficulties in evaluating /sup 99m/Tc-PMT uptake by small hepatic tumors; overlapping of radioactivity in the gut and gallbladder in delayed /sup 99m/Tc-PMT images of tumors. This study indicates that delayed /sup 99m/Tc-PMT images can be useful in the diagnosis of hepatocellular carcinoma

    Hepatocellular carcinoma is the most common primary liver cancer and it represents the majority of cancer-related deaths in the world. More than 70% of patients present at an advanced stage, beyond potentially curative options. Ytrrium-90 selective internal radiation therapy (Y90-SIRT) with glass microspheres is rapidly gaining acceptance as a potential therapy for intermediate and advanced stage primary hepatocellular carcinoma and liver metastases. The technique involves delivery of Y90 infused glass microspheres via the hepatic arterial blood flow to the appropriate tumor. The liver tumor receives a highly concentrated radiation dose while sparing the healthy liver parenchyma due to its preferential blood supply from portal venous blood. There are two commercially available devices: TheraSphere® and SIR-Spheres®. Although, Y90-SIRT with glass microspheres improves median survival in patients with intermediate and advanced hepatocellular carcinoma and has the potential to downstage hepatocellular carcinoma so that the selected candidates meet the transplantable criteria, it has not gained widespread acceptance due to the lack of large randomized controlled trials. Currently, there are various clinical trials investigating the use of Y90-SIRT with glass microspheres for treatment of hepatocellular carcinoma and the outcomes of these trials may result in the incorporation of Y90-SIRT with glass microspheres into the treatment guidelines as a standard therapy option for patients with intermediate and advanced stage hepatocellular carcinoma

    Hepatocellular carcinoma is one of the most frequent types of malignant tumors in the world. There is growing evidence of the relationship between it development and obesity. The mechanism that links obesity to cancer is still not fully understood; however, it is essential to the understanding the adipose tissue in metabolic changes related to obesity and hepatocellular carcinoma. To review the influence of serum leptin levels in patients with hepatocelular carcinoma. Systematic review of the literature based on the methodology of the Cochrane Institute. The search for articles was in the database: Science Direct, Scielo, Medline, Lilacs e Pubmed. The key words used were hepatocellular carcinoma, leptin, adipokine. After evaluation of individual studies, were selected seven studies. The results previously studied are still inconsistent and contradictory, and leptin can be effectively involved in the occurrence and development of hepatocellular carcinoma. Therefore, it is necessary to develop prospective, well-designed and conducted focusing on the role and specific mechanisms of this hormone in patients with hepatocellular carcinoma, so that new correlations can be properly supported. O carcinoma hepatocelular é um dos tipos mais frequentes de tumores malignos no mundo. Há crescentes evidências da relação entre o seu desenvolvimento e a obesidade.

    To retrospectively compare treatment of hepatocellular carcinoma (HCC) with transarterial chemoembolization (TACE) using gelatin sponges or microspheres plus lipiodol-doxorubicin vs. doxorubicin-loaded drug-eluting beads (DEB). A total of 158 patients with HCC received TACE from November 2010 to November 2011 were enrolled in this study, including 64 (40.5%) received TACE with lipiodol-doxorubicin and gelatin sponges (group A), 41 (25.9%) received TACE with lipiodol-doxorubicin and microspheres (group B), and 53 (33.5%) received TACE with doxorubicin-loaded DEB (group C). Tumor response and adverse events (AEs) were evaluated. No significant difference was found at baseline among the three groups. The doxorubicin dosage in group C was significantly (p < 0.001) higher compared to the dose used in groups A or B (median, 50 mg vs. 31 mg or 25 mg). Significantly (p < 0.001) more patients in group C achieved complete response compared to those in groups A or B (32.1% vs. 6.3% or 2.4%). Significantly (p < 0.001) less patients in group C had progressive disease compared to those in groups A or B (34.0% vs. 57.8% or 68.3%). Minor AEs were more common in groups A and B compared to group C, with rates of 54.7%, 34.1%, and 5.7%, respectively. In patients with HCC, TACE with DEB offers better safety and efficacy profiles compared to either TACE with gelatin sponges or TACE with microspheres.

    This prospective study was to investigate the value of [ 11 C]-acetate PET and [ 18 F]-FDG PET in the evaluation of hepatocellular carcinoma (HCC) before and after treatment with transarterial chemoembolization (TACE) and vascular endothelial growth factor (VEGF) antibody (bevacizumab). Twenty-two patients (three women, 19 men; 62 ± 8 years) with HCC verified by histopathology were treated with TACE and bevacizumab (n = 11) or placebo (n = 11). [ 11 C]-acetate PET and [ 18 F]-FDG PET were performed before and after TACE with bevacizumab or placebo. Comparisons between groups were performed with t-tests and Chi-squared tests, where appropriate. Overall survival (OS) was defined as the time from start of bevacizumab or placebo until the date of death/last follow-up, respectively. The patient-related sensitivity of [ 11 C]-acetate PET, [ 18 F]-FDG PET, and combined [ 11 C]-acetate and [ 18 F]-FDG PET was 68%, 45%, and 73%, respectively. There was a significantly higher rate of conversion from [ 11 C]-acetate positive lesions to negative lesions in patients treated with TACE and bevacizumab as compared with that in patients with TACE and placebo (p < 0.05). In patients with negative acetate PET, the mean OS in patients treated with TACE and bevacizumab was 259 ± 118 days and was markedly shorter as compared with that (668 ± 217 days) in patients treated with TACE and placebo (p < 0.05). In patients treated with TACE and placebo, there was significant difference in mean OS in patients with positive FDG PET as compared with that in patients with negative FDG PET (p < 0.05). The HCC lesions had different tracer avidities showing the heterogeneity of HCC. Our study suggests that combining [ 18 F]-FDG with [ 11 C]-acetate PET could be useful for the management of HCC patients and might also provide relevant prognostic and molecular heterogeneity information.

    2015-01-01

    The incidence of hepatocellular carcinoma (HCC) is increasing, and it is currently the second leading cause of cancer-related death worldwide. Potentially curative treatment options for HCC include resection, transplantation, and percutaneous ablation, whereas palliative treatments include trans-arterial chemoembolization (TACE), radioembolization, and systemic treatments. Due to the diversity of available treatment options and patients’ presentations, a multidisciplinary team should decide clinical management of HCC, according to tumor characteristics and stage of liver disease. Potentially curative treatments are suitable for very-early- and early-stage HCC. However, the vast majority of HCC patients are diagnosed in later stages, where the tumor characteristics or progress of liver disease prevent curative interventions. For patients with intermediate-stage HCC, TACE and radioembolization improve survival and are being evaluated in addition to potentially curative therapies or with systemic targeted therapy. There is currently no effective systemic chemotherapy, immunologic, or hormonal therapy for HCC, and sorafenib is the only approved molecular-targeted treatment for advanced HCC. Other targeted agents are under investigation; trials comparing new agents in combination with sorafenib are ongoing. Combinations of systemic targeted therapies with local treatments are being evaluated for further improvements in HCC patient outcomes. This article provides an updated and comprehensive overview of the current standards and trends in the treatment of HCC. PMID:25866604

    Rottlerin has been reported to exert its anti-tumor activity in various types of human cancers. However, the underlying molecular mechanism has not been fully elucidated. In the current study, we explored whether rottlerin exhibits its tumor suppressive function in hepatocellular carcinoma cells. Our MTT assay results showed that rottlerin inhibited cell growth in hepatocellular carcinoma cells. Moreover, we found that rottlerin induced cell apoptosis and caused cell cycle arrest at G1 phase. Furthermore, our wound healing assay result demonstrated that rottlerin retarded cell migration in hepatocellular carcinoma cells. Additionally, rottlerin suppressed cell migration and invasion. Notably, we found that rottlerin upregulated DDX3 expression and subsequently downregulated Cyclin D1 expression and increased p21 level. Importantly, down-regulation of DDX3 abrogated the rottlerin-mediated tumor suppressive function, whereas overexpression of DDX3 promoted the anti-tumor activity of rottlerin. Our study suggests that rottlerin exhibits its anti-cancer activity partly due to upregulation of DDX3 in hepatocellular carcinoma cells. Copyright © 2017 Elsevier Inc. All rights reserved.

    Hepatocellular carcinoma is a very common neoplastic disease in countries where hepatitis viruses B and/or C are prevalent. Small hepatocellular carcinoma lesions detected by ultrasonography at an early stage are often hyperechoic because they are composed of well-differentiated cancer cells that are rich in triglyceride droplets. The triglyceride content of hepatocytes depends in part on the rate of lipogenesis. Key lipogenic enzymes, such as fatty acid synthase, are co-ordinately regulated at the transcriptional level. We therefore examined the mRNA expression of lipogenic enzymes in human hepatocellular carcinoma samples from 10 patients who had undergone surgical resection. All of the samples exhibited marked elevation of expression of mRNA for lipogenic enzymes, such as fatty acid synthase, acetyl-CoA carboxylase and ATP citrate lyase, compared with surrounding non-cancerous liver tissue. In contrast, the changes in mRNA expression of SREBP-1, a transcription factor that regulates a battery of lipogenic enzymes, did not show a consistent trend. In some cases where SREBP-1 was elevated, the main contributing isoform was SREBP-1c rather than SREBP-1a. Thus, lipogenic enzymes are markedly induced in hepatocellular carcinomas, and in some cases SREBP-1c is involved in this activation.

    Full Text Available Abstract Background More than 50% of the worldwide cases of hepatocellular carcinoma occur in China, and this malignancy currently represents the country's second leading cause of cancer death in cities and the leading cause in rural areas. Despite recent advances in the control and management of hepatocellular carcinoma within China, this disease remains a major health care issue. The global HCC BRIDGE study, designed to assess patterns of hepatocellular carcinoma therapy use and associated outcomes across real-world clinical practice, has recently been expanded as a national study in China, allowing a detailed analysis of hepatocellular carcinoma in this important country. Methods/Design The global HCC BRIDGE study is a multiregional longitudinal cohort trial including patients newly diagnosed with hepatocellular carcinoma between January 1, 2005, and June 30, 2011, who are receiving treatment for hepatocellular carcinoma via sites in the Asia-Pacific, European, and North American regions. The HCC BRIDGE China national study comprises the portion of the global HCC BRIDGE study conducted within mainland China. Patients will be followed from time of diagnosis of hepatocellular carcinoma (post-January 1, 2005 to time of death or December 31, 2011, whichever comes first. Data will be collected on demographic/clinical characteristics, relevant laboratory values, hepatocellular carcinoma/underlying liver disease treatment, tumor response, adverse events, hospitalizations, and overall survival. The primary study end point is overall survival; secondary end points are disease progression, treatment-limiting adverse events, and treatment failure. Results At the time of writing, 15 sites have selected for participation across all 7 traditional regions of China (North, North-East, East, South, South-West, North-West, and Central. The anticipated study population from the China national study is approximately 9000 patients. Discussion Findings from the

    Bone metastases are rare in primary hepatocellular carcinoma (HCC). Spinal cord compression (SCC) due to bone metastases occur commonly in patients with lung and breast carcinomas, and metastatic HCC is an unusual cause of SCC. Spinal cord compression is an oncologic emergency and treatment delays can lead to irreversible consequences. Thus, the awareness that SCC could be a potential complication of bone metastases due to HCC is of significance in initiation of early treatment that can improve the quality of life and survival of the patients, if diagnosed earlier. This paper describes four cases of primary HCC with varied manifestations of SCC due to bone metastases. The first patient presented primarily with the symptoms of bone pains corresponding to the bone metastases sites rather than symptoms of associated hepatic pathology and eventually developed SCC. The second patient, diagnosed as having HCC, developed extradural SCC leading to paraplegia during the course of illness, for which he underwent emergency laminectomy with posterior fixation. The third patient developed SCC soon after the primary diagnosis and had to undergo emergency laminectomy. Post laminectomy he had good neurological recovery. The Fourth patient presented primarily with radicular pains rather than frank paraplegia as the first manifestation of SCC. PMID:16937544

    AIM: To assess the practice of Egyptian physicians in screening patients for hepatocellular carcinoma(HCC). METHODS: The study included 154 physicians from all over Egypt caring for patients at risk for HCC. The study was based on a questionnaire with 20 items. Each questionnaire consisted of two parts:(1) personal information regarding the physician(name, age, specialty and type of health care setting); and(2) professional experience in the care of patients at risk for HCC development(screening, knowledge about the cause and natural course of liver diseases and HCC risk). RESULTS: Sixty-eight percent of doctors with an MD degree, 48% of doctors with a master degree or a diploma and 40% of doctors with a Bachelor of Medicine, Bachelor of Surgery certificate considered the hepatitis C virus(HCV) genotype as risk factor for HCC development(P < 0.05). Ninety percent of physicians specialized in tropical medicine, internal medicine or gastroenterology and 67% of physicians in other specialties advise patients to undergo screening for HCV and hepatitis B virus infection as well as liver cirrhosis(P < 0.05). Eighty-six percent of doctors in University Hospitals and 69% of Ministry of Health(MOH) doctors consider HCV infection as the leading cause of HCC in Egypt(P < 0.05). Seventy-two percent of doctors with an MD degree, 55% of doctors with a master degree or a diploma, 56% of doctors with an MBBCH certificate, 74% of doctors in University Hospitals and 46% of MOH hospital doctors consider abdominal ultrasonography as the most important investigation in HCC screening(P < 0.05). Sixty-five percent of physicians in tropical medicine, internal medicine or gastroenterology and 37% of physicians in other specialties recommend as HCC screening interval of 3 mo(P < 0.05). Seventy-one percent of doctors with an MD degree, 50% of doctors with a master degree or diploma and 60% of doctors with an MBBCH certificate follow the same recommendation.CONCLUSION: In Egypt, physicians

    Yttrium-90 transarterial radioembolization (TARE) is a locoregional therapy (LRT) for hepatocellular carcinoma (HCC). In this study, we present overall survival (OS) outcomes in a 1,000-patient cohort acquired over a 15-year period. Between December 1, 2003 and March 31, 2017, 1,000 patients with HCC were treated with TARE as part of a prospective cohort study. A comprehensive review of toxicity and survival outcomes was performed. Outcomes were stratified by baseline Child-Pugh (CP) class, United Network for Organ Sharing (UNOS), and Barcelona Clinic Liver Cancer (BCLC) staging systems. Albumin and bilirubin laboratory toxicities were compared to baseline. OS outcomes were reported using censoring and intention-to-treat methodologies. All treatments were outpatient, with a median one treatment per patient. Five hundred six (51%) were CP A, 450 (45%) CP B, and 44 (4%) CP C. Two hundred sixty-three (26%) patients were BCLC A, 152 (15%) B, 541 (54%) C, and 44 (4%) D. Three hundred sixty-eight (37%) were UNOS T1/T2, 169 (17%) T3, 147 (15%) T4a, 223 (22%) T4b, and 93 (9%) N/M. In CP A patients, censored OS for BCLC A was 47.3 (confidence interval [CI], 39.5-80.3) months, BCLC B 25.0 (CI, 17.3-30.5) months, and BCLC C 15.0 (CI, 13.8-17.7) months. In CP B patients, censored OS for BCLC A was 27 (CI, 21-30.2) months, BCLC B 15.0 (CI, 12.3-19.0) months, and BCLC C 8.0 (CI, 6.8-9.5) months. Forty-nine (5%) and 110 (11%) patients developed grade 3/4 albumin and bilirubin toxicities, respectively. Based on our experience with 1,000 patients over 15 years, we have made a decision to adopt TARE as the first-line transarterial LRT for patients with HCC. Our decision was informed by prospective data and incrementally reported demonstrating outcomes stratified by BCLC, applied as either neoadjuvant or definitive treatment.

    Local treatment for hepatocellular carcinoma (HCC) has been widely used in clinical practice due to its minimal invasiveness and high rate of cure. Percutaneous radiofrequency ablation (RFA) is widely used because its treatment effectiveness. However, some serious complications can arise from percutaneous RFA. We present here a rare case of hemorrhagic cardiac tamponade secondary to an anterior cardiac vein (right marginal vein) injury during RFA for treatment of HCC.

    2016-01-01

    Transarterial chemoembolization (TACE) is a widely used standard treatment for patients with hepatocellular carcinoma (HCC) who are not suitable candidates for curative treatments. The rationale for TACE is that intra-arterial chemotherapy using lipiodol and chemotherapeutic agents, followed by selective vascular embolization, results in a strong cytotoxic effect as well as ischemia (conventional TACE). Recently, drug-eluting beads (DC Beads®) have been developed for transcatheter treatment of HCC to deliver higher doses of the chemotherapeutic agent and to prolong contact time with the tumor. DC Beads® can actively sequester doxorubicin hydrochloride from solution and release it in a controlled sustained fashion. Treatment with DC Beads® substantially reduced the amount of chemotherapeutic agent that reached the systemic circulation compared with conventional, lipiodol-based regimens, significantly reducing drug-related adverse events. In this article, we describe the treatment response, survival, and safety of TACE used with drug-eluting beads for the treatment of HCC and discuss future therapeutic possibilities. PMID:27833376

Instructor, Department of Technology of radiology, Faculty of Para-Medicine, Shahid Beheshti University of medical sciences Abstract Background: Photoelectron therapy method has been usad successfully, on the body phantom, cancer cells culture and animals. In this method, drugs containing x-Ray opaque factors–with high atomic numbers–are injected into the patient’s vein. After appropriate drug accumulation, about at least ten percent of the total injected amounts, 200kev. up to 300kev. of localized x-Ray beams is radiated to the site of the tumor. The Ethic Committee of Shahid Beheshti University of Medical Education and Health Services authorized the implementation of this new cancer treatment method, initially only on the group of patients who suffered from hepato-cellular carcinoma. Hepato cellular carcinoma is one of the most current malignancies of liver. In some cases, in addition to surgery, several approaches exist to come near the aim of predominating hepato-cellular carcinoma such as chemotherapy, current Radiation Therapy, Radio-Frequency application (RF, Trans-Artepical Chemo Embolization, (TACE, and Percutaneous Ethanol Injection (PEI. The effectiveness of the above-mentioned methods is about 10%-47%, applied alone or along side each other. Materials and methods: This study was a clinical-trial one. In this study, first, lipiodol (an x-ray opaque material with a high atomic number was transferred into the main vessel terminating to the tumor by angio-catheterization. Then,200kev. up to 250kev. of localized x-ray was radiated to the site of the tumor in one session. The drug volume was proportionally selected to the volume of the tumor, and the irradiation intensity was between 400 to 600cent.Gy. the beam energy absorption capacity of this drug is as times as

    Several scoring systems that guide patients' treatment regimen for transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC) have been introduced, but none have gained widespread acceptance in clinical practice. The purpose of this study is to externally validate the Selection for TrAnsarterial chemoembolization TrEatment (STATE)-score and START-strategy [i.e., sequential use of the STATE-score and Assessment for Retreatment with TACE (ART)-score]. From January 2000 to September 2015, 933 patients with HCC underwent TACE at our institution. All variables needed to calculate the STATE-score and implement the START-strategy were determined. STATE comprised serum albumin, up-to-seven criteria, and C-reactive protein (CRP). ART comprised an increase in aspartate aminotransferase, the Child-Pugh score, and a radiological tumor response. Overall survival was calculated, and multivariate analysis performed. In addition, the STATE-score and START-strategy were validated using the Harrell's C-index and integrated Brier score (IBS). The STATE-score was calculated in 228 patients. Low and high STATE-scores corresponded to median survival of 14.3 and 20.2 months, respectively. Harrell's C was 0.558 and IBS 0.133. For the STATE-score, significant predictors of survival were up-to-seven criteria (p = 0.006) and albumin (p = 0.022). CRP values were not predictive (p = 0.367). The ART-score was calculated in 207 patients. Combining the STATE-score and ART-score led to a Harrell's C of 0.580 and IBS of 0.132. The STATE-score was unable to reliably determine the suitability for initial TACE. The START-strategy only slightly improved the predictive ability compared to the ART-score alone. Therefore, neither the STATE-score nor START-strategy alone provides sufficient certainty for clear-cut clinical decisions.

    To investigate the value of quantitative iodine-based material decomposition images with gemstone spectral CT imaging in the follow-up of patients with hepatocellular carcinoma (HCC) after transcatheter arterial chemoebolization (TACE). Consecutive 32 HCC patients with previous TACE treatment were included in this study. For the follow-up, arterial phase (AP) and venous phase (VP) dual-phase CT scans were performed with a single-source dual-energy CT scanner (Discovery CT 750HD, GE Healthcare). Iodine concentrations were derived from iodine-based material-decomposition images in the liver parenchyma, tumors and coagulation necrosis (CN) areas. The iodine concentration difference (ICD) between the arterial-phase (AP) and venal-phase (VP) were quantitatively evaluated in different tissues.The lesion-to-normal parenchyma iodine concentration ratio (LNR) was calculated. ROC analysis was performed for the qualitative evaluation, and the area under ROC (Az) was calculated to represent the diagnostic ability of ICD and LNR. In all the 32 HCC patients, the region of interesting (ROI) for iodine concentrations included liver parenchyma (n=42), tumors (n=28) and coagulation necrosis (n=24). During the AP the iodine concentration of CNs (median value 0.088 µg/mm(3)) appeared significantly higher than that of the tumors (0.064 µg/mm(3), P=0.022) and liver parenchyma (0.048 µg/mm(3), P=0.005). But it showed no significant difference between liver parenchyma and tumors (P=0.454). During the VP the iodine concentration in hepatic parenchyma (median value 0.181 µg/mm(3)) was significantly higher than that in CNs (0.140 µg/mm(3), P=0.042). There was no significant difference between liver parenchyma and tumors, CNs and tumors (both P>0.05). The median value of ICD in CNs was 0.006 µg/mm(3), significantly lower than that of the HCC (0.201 µg/mm(3), Piodine-based material decomposition images with gemstone spectral CT imaging can improve the diagnostic efficacy of CT imaging

  7. Galectin-1-Induced Autophagy Facilitates Cisplatin Resistance of Hepatocellular Carcinoma.

    Directory of Open Access Journals (Sweden)

    Full Text Available Hepatocellular carcinoma (HCC is one of the most common cancers in Taiwan. Although chemotherapy is the primary treatment for HCC patients, drug resistance often leads to clinical failure. Galectin-1 is a beta-galactoside binding lectin which is up-regulated in HCC patients and promotes tumor growth by mediating cancer cell adhesion, migration and proliferation, but its role in chemoresistance of HCC is poorly understood. In this study we found that galectin-1 is able to lead to chemoresistance against cisplatin treatment, and subsequent inhibition has reversed the effect of cell death in HCC cells. Moreover, galectin-1 was found to induce autophagic flux in HCC cells. Inhibition of autophagy by inhibitors or knockdown of Atg5 cancels galectin-1-induced cisplatin resistance in HCC cells. Increase of mitophagy triggered by galectin-1 was found to reduce the mitochondrial potential loss and apoptosis induced by cisplatin treatment. Finally, using an in situ hepatoma mouse model, we clearly demonstrated that inhibition of galectin-1 by thiodigalactoside could significantly augment the anti-HCC effect of cisplatin. Taken together, our findings offer a new insight into the chemoresistance galectin-1 causes against cisplatin treatment, and points to a potential approach to improve the efficacy of cisplatin in the treatment of HCC patients.

    Hepatocellular adenoma (HCA) is a rare, benign proliferation of hepatocytes that occurs mostly in a normal liver and in extreme rare cases, occurs in a cirrhotic liver. Hepatocellular carcinomas (HCC) arising within HCA through malignant transformation is rare. The specific incidence and mechanism of malignant transformation has not been established, but the long term use of oral contraceptives is considered a causative agent. We report a case of HCC arising from HCA detected in a hepatitis B-related cirrhotic liver with serial radiologic images.

    There are no systemic treatments for patients with hepatocellular carcinoma (HCC) whose disease progresses during sorafenib treatment. We aimed to assess the efficacy and safety of regorafenib in patients with HCC who have progressed during sorafenib treatment. In this randomised, double-blind, parallel-group, phase 3 trial done at 152 sites in 21 countries, adults with HCC who tolerated sorafenib (≥400 mg/day for ≥20 of last 28 days of treatment), progressed on sorafenib, and had Child-Pugh A liver function were enrolled. Participants were randomly assigned (2:1) by a computer-generated randomisation list and interactive voice response system and stratified by geographical region, Eastern Cooperative Oncology Group performance status, macrovascular invasion, extrahepatic disease, and α-fetoprotein level to best supportive care plus oral regorafenib 160 mg or placebo once daily during weeks 1-3 of each 4-week cycle. Investigators, patients, and the funder were masked to treatment assignment. The primary endpoint was overall survival (defined as time from randomisation to death due to any cause) and analysed by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01774344. Between May 14, 2013, and Dec 31, 2015, 843 patients were screened, of whom 573 were enrolled and randomised (379 to regorafenib and 194 to placebo; population for efficacy analyses), and 567 initiated treatment (374 received regorafenib and 193 received placebo; population for safety analyses). Regorafenib improved overall survival with a hazard ratio of 0·63 (95% CI 0·50-0·79; one-sided p<0·0001); median survival was 10·6 months (95% CI 9·1-12·1) for regorafenib versus 7·8 months (6·3-8·8) for placebo. Adverse events were reported in all regorafenib recipients (374 [100%] of 374) and 179 (93%) of 193 placebo recipients. The most common clinically relevant grade 3 or 4 treatment-emergent events were hypertension (57 patients [15%] in the regorafenib group

    Orthotopic liver transplantation is a curative treatment for hepatocellular carcinoma within Milan criteria, but these criteria preclude many patients from transplant candidacy. Recent studies have demonstrated that downstaging therapy can reduce tumor burden to meet conventional criteria. The present study reports a single-center experience with tumor downstaging and its effects on post-orthotopic liver transplantation outcomes. All patients with hepatocellular carcinoma who were evaluated by our multidisciplinary liver services team from 2012 to 2016 were identified (N = 214). Orthotopic liver transplantation candidates presenting outside of Milan criteria at initial radiographic diagnosis and/or an initial alpha-fetoprotein >400 ng/mL were categorized as at high risk for tumor recurrence and post-transplant mortality. Of the 214 patients newly diagnosed with hepatocellular carcinoma, 73 (34.1%) eventually underwent orthotopic liver transplantation. The majority of patients who did not undergo orthotopic liver transplantation were deceased or lost to follow-up (47.5%), with 14 of 141 (9.9%) currently listed for transplantation. Among transplanted patients, 21 of 73 (28.8%) were considered high-risk candidates. All 21 patients were downstaged to within Milan criteria with an alpha-fetoprotein hepatocellular carcinoma was higher but acceptable between downstaged high-risk and traditional candidates (9.5% vs 1.9%; P > .05) at a median follow-up period of 17 months. Downstaged high-risk candidates had a similar overall survival compared with those transplanted within Milan criteria (log-rank P > .05). In highly selected cases, patients with hepatocellular carcinoma outside of traditional criteria for orthotopic liver transplantation may undergo downstaging therapy in a multidisciplinary fashion with excellent post-transplant outcomes. These data support an aggressive downstaging approach for selected patients who would otherwise be deemed ineligible for

    Orthotopic liver transplantation (OLT) is the best treatment option for selected patients with hepatocellular carcinoma (HCC) with the background of cirrhosis since this treatment modality can cure both diseases at once. Over the years, the applicability of OLT for HCC has evolved. In Asia, including Hong Kong, a shortage of deceased donor liver grafts is a universal problem having to be faced in all transplant centers. Living-donor liver transplant (LDLT) has therefore been developed to counteract organ shortage and the high prevalence of HCC. The application of LDLT for HCC is a complex process involving donor voluntarism, selection criteria for the recipient and justification with respect to long-term survival in comparison to the result of deceased donor liver transplant. This article reviews the authors' experience with OLT for HCC patients in Hong Kong, with emphasis on the applicability and outcome of LDLT for HCC. Donor voluntarism has a significant impact on the application of LDLT. "Fast-track" LDLT in the setting of recurrence following curative treatment carries a high risk of recurrence even though the tumor stage fulfills the standard criteria. Although the survival outcome may be worse following LDLT than DDLT for HCC, LDLT is still the main treatment option for patients with transplantable HCC in Hong Kong, and a reasonable survival outcome can be achieved in selected patients with extended indications. It is particularly true that LDLT provides the only hope for patients with advanced HCC under the constricting problem of organ shortage.

    PurposeTo prospectively compare SIRT and DEB-TACE for treating hepatocellular carcinoma (HCC).MethodsFrom 04/2010–07/2012, 24 patients with histologically proven unresectable N0, M0 HCCs were randomized 1:1 to receive SIRT or DEB-TACE. SIRT could be repeated once in case of recurrence; while, TACE was repeated every 6 weeks until no viable tumor tissue was detected by MRI or contraindications prohibited further treatment. Patients were followed-up by MRI every 3 months; the final evaluation was 05/2013.ResultsBoth groups were comparable in demographics (SIRT: 8males/4females, mean age 72 ± 7 years; TACE: 10males/2females, mean age 71 ± 9 years), initial tumor load (1 patient ≥25 % in each group), and BCLC (Barcelona Clinic Liver Cancer) stage (SIRT: 12×B; TACE 1×A, 11×B). Median progression-free survival (PFS) was 180 days for SIRT versus 216 days for TACE patients (p = 0.6193) with a median TTP of 371 days versus 336 days, respectively (p = 0.5764). Median OS was 592 days for SIRT versus 788 days for TACE patients (p = 0.9271). Seven patients died in each group. Causes of death were liver failure (n = 4 SIRT group), tumor progression (n = 4 TACE group), cardiovascular events, and inconclusive (n = 1 in each group).ConclusionsNo significant differences were found in median PFS, OS, and TTP. The lower rate of tumor progression in the SIRT group was nullified by a greater incidence of liver failure. This pilot study is the first prospective randomized trial comparing SIRT and TACE for treating HCC, and results can be used for sample size calculations of future studies.

Twenty-two patients (three women, 19 men; 62 ± 8 years) with HCC verified by histopathology were treated with TACE and bevacizumab (n = 11) or placebo (n = 11). [{sup 11}C]-acetate PET and [{sup 18}F]-FDG PET were performed before and after TACE with bevacizumab or placebo. Comparisons between groups were performed with t-tests and Chi-squared tests, where appropriate. Overall survival (OS) was defined as the time from start of bevacizumab or placebo until the date of death/last follow-up, respectively. The patient-related sensitivity of [{sup 11}C]-acetate PET, [{sup 18}F]-FDG PET, and combined [{sup 11}C]-acetate and [{sup 18}F]-FDG PET was 68%, 45%, and 73%, respectively. There was a significantly higher rate of conversion from [{sup 11}C]-acetate positive lesions to negative lesions in patients treated with TACE and bevacizumab as compared with that in patients with TACE and placebo (p < 0.05). In patients with negative acetate PET, the mean OS in patients treated with TACE and bevacizumab was 259 ± 118 days and was markedly shorter as compared with that (668 ± 217 days) in patients treated with TACE and placebo (p < 0.05). In patients treated with TACE and placebo, there was significant difference in mean OS in patients with positive FDG PET as compared with that in patients with negative FDG PET (p < 0.05). The HCC lesions had different tracer avidities showing the heterogeneity of HCC. Our study suggests that combining [{sup 18}F]-FDG with [{sup 11}C]-acetate PET could be useful for the management of HCC patients and might also provide relevant prognostic and molecular heterogeneity information.

    To evaluate the clinical efficacy and survival rate of transarterial chemoembolization (TACE) alone or plus radiofrequency ablation (RFA) in patients with intermediate or advanced stage primary hepatocellular carcinoma (HCC). In this retrospective study, 467 cases received RFA or TACE plus RFA. Among them, 167 cases with strict clinical procedure (TACE alone or plus RFA) and complete follow-up data were included. Eighty-seven cases received TACE and 80 cases had TACE plus RFA between January 2000 and December 2006. Hierarchical analyses were performed using log-rank tests and survival curve was estimated by Kaplan-Meier method. A total of 167 patients received TACE alone or plus RFA for a follow-up period of 1 to 89 months. In the TACE alone group, the time-to-progression (TTP) was an average of 3.6 months. The median survival was 13 months, one-year survival rate 52.9%, three-year survival rate 11.5% and five-year survival rate 4.6%. In the TACE plus RFA group, the TTP time was an average of 10.8 months. The median survival time was 30 months, one-year survival rate 85.0%, three-year survival rate 45.0% and five-year survival rate 11.3%. In the TACE alone group, the median survival of intermediate stage HCC was 14 months, one-year survival rate 62.2%, three-year survival rate 13.3% and five-year survival rate 4.4%; In the TACE plus RFA group, the median survival of intermediate stage HCC was 14 months, one-year survival rate 90.1%, three-year survival rate 52.9% and five-year survival rate 13.7%.

    Purpose: Selective-internal-radiation-therapy (SIRT) and transarterial-chemoembolization (TACE) are commonly used for treatment of liver tumors. The use of TACE, which is macroembolic, prior to SIRT may cause hemodynamic changes in tumor vasculature that impair yttrium-90 (90Y) microsphere delivery to the targeted lesions. This work aims to quantify dosimetric tumor coverage using 90Y positron emission tomography (PET) dosimetry after SIRT alone compared to TACE followed by SIRT. Methods: A total of 40 consecutive hepatocellular carcinoma (HCC) SIRT patients who had a post-SIRT 90Y PET/CT scan were evaluated. The patient-specific-3D-dose was reconstructed from the PET images. Patients were categorized into two groups: patients received TACE prior SIRT procedure (n=18) and patient received SIRT alone (n=22). The lesions and liver were delineated by a senior radiologist. We evaluated both the lesion-specific dose-volume-histogram (DVH) and the selectivity index (SI) defined as the ratio of the average dose inside the total lesion(s) and the average dose of the normal liver. The SI values of patients were compared based on whether TACE was previously used. Results: A wide spectrum was observed in the lesion-specific DVH-evaluation and SI appeared to be suitable of evaluating the quality of each SIRT infusion. The average SI of the entire patient group was 3.0, i.e. targeted lesion receiving three times higher dose than normal liver. The average SI was 1.8 for patients who had prior TACE and 3.9 for patients who did not have prior TACE (p=0.008). 85% of the patients with prior TACE demonstrated poor 90Y-microsphere delivery (SI <2) while none demonstrated excellent delivery (SI >4). On the other hand, the incidence SI >4 among patients with no prior TACE was 37%. Conclusion: 3D dose evaluation using post-SIRT PET suggests that 90Y microsphere delivery to liver tumors is impaired among patients who received prior TACE compared to those who receive SIRT alone.

    The clinical presentation of hepatocellular carcinoma (HCC differs between patients in developing countries (African and Chinese populations from those in industrialized countries. In industrialized countries, HCC co-exists with symptomatic cirrhosis in 80% of cases and clinical manifestations are usually related to those of the underlying disease. On the other hand, patients from developing countries have HCC and cirrhosis in approximately 40% of cases. Underlying cirrhosis in many cases is not advanced and does not produce any symptoms or associated symptoms are masked by those of the tumor (right upper quadrant pain, mass in the upper abdomen, weight loss and weakness. In a subset of patients, there are no clinical manifestations as HCC may occur in the context of hepatitis B infection without cirrhosis.

    Clinical Manifestations

    In Western countries, nearly 35% percent of patients with HCC are asymptomatic. Some of the most common clinical manifestations include: abdominal pain (53-58% of patients, especially in epigastrium or right upper quadrant, abdominal mass (30%, weight loss, malaise, anorexia, cachexia, jaundice or fever.

    Physical Exam

    Physical findings vary with the stage of disease. The patient may exhibit slight or moderate wasting when first seen. In patients with cirrhosis, typical stigmata of chronic liver disease may be present. In advanced stages of HCC the liver may be enlarged and there is significant tenderness. An arterial bruit may be heard over the liver

    Glucose consumption in many types of cancer cells, in particular hepatocellular carcinoma (HCC), was followed completely by over-expression of type II hexokinase (HKII). This evidence has been used in modern pharmacotherapy to discover therapeutic target against glycolysis in cancer cells. Bromopyruvate (BrPA) exhibits antagonist property against HKII and can be used to inhibit glycolysis. However, the clinical application of BrPA is mostly combined with inhibition effect for healthy cells particularly erythrocytes. Our strategy is to encapsulate BrPA in a selected vehicle, without any leakage of BrPA out of vehicle in blood stream. This structure has been constructed from chitosan embedded into oleic acid layer and then coated by dual combination of folic acid (FA) and bovine serum albumin (BSA). With FA as specific ligand for cancer folate receptor and BSA that can be an easy binding for hepatocytes, they can raise the potential selection of carrier system. PMID:29320411

    Hepatocellular carcinomas exhibit heterogeneous morphologies by routine light microscopy. Although some morphologies represent insignificant variations in growth patterns, others may represent unrecognized subtypes of hepatocellular carcinoma. Identification of these subtypes could lead to separation of hepatocellular carcinomas into discrete groups with unique underlying genetic changes, prognosis, or therapeutic responses. In order to identify potential subtypes, two pathologists independently screened a cohort of 219 unselected hepatocellular carcinoma resection specimens and divided cases into potential subtypes. One of these promising candidate subtypes was further evaluated using histological and molecular techniques. This subtype was characterized by a unique and consistent set of histological features: smooth chromophobic cytoplasm, abrupt focal nuclear anaplasia (small clusters of tumor cells with marked nuclear anaplasia in a background of tumor cells with bland nuclear cytology), and scattered microscopic pseudocysts--we designate this variant as 'chromophobe hepatocellular carcinoma with abrupt anaplasia'. Thirteen cases were identified (6% of all hepatocellular carcinomas), including 6 men and 7 women with an average age of 61 years. Six cases occurred in cirrhotic livers. Serum AFP was elevated in 6 out of 10 cases. There were a variety of underlying liver diseases, but cases were enrichment for chronic hepatitis B, P=0.006. Interestingly, at the molecular level, this variant was strongly associated with the alternative lengthening of telomere (ALT) phenotype by telomere FISH. ALT is a telomerase-independent mechanism of telomere maintenance and is found in approximately 8% of unselected hepatocellular carcinomas. In contrast, 11/12 (92%) of the cases of chromophobe hepatocellular carcinoma with abrupt anaplasia were ALT-positive. In summary, we propose that chromophobe hepatocellular carcinoma with abrupt anaplasia represents a new subtype of

    AIM: To evaluate the efficacy of ursodeoxycholic acid (UDCA) as a chemotherapeutic agent for the treatment of hepatocellular carcinoma (HCC). METHODS: BALB/c nude mice were randomized into four groups 24 h before subcutaneous injection of hepatocarcinoma BEL7402 cells suspended in phosphate buffered saline (PBS) into the right flank. The control group (n = 10) was fed a standard diet while treatment groups (n = 10 each) were fed a standard daily diet supplemented with different concentrations of UDCA (30, 50 and 70 mg/kg per day) for 21 d. Tumor growth was measured once each week, and tumor volume (V) was calculated with the following equation: V = (L × W2) × 0.52, where L is the length and W is the width of the xenograft. After 21 d, mice were killed under ether anesthesia, and tumors were excised and weighed. Apoptosis was evaluated through detection of DNA fragmentation with gel electrophoresis and the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay. Western blot analysis was performed to determine the expression of apoptosis-related proteins BAX, BCL2, APAF1, cleaved caspase-9, and cleaved caspase-3. RESULTS: UDCA suppressed tumor growth relative to controls. The mean tumor volumes were the following: control, 1090 ± 89 mm3; 30 mg/kg per day, 612 ± 46 mm3; 50 mg/kg per day, 563 ± 38 mm3; and 70 mg/kg per day, 221 ± 26 mm3. Decreased tumor volumes reached statistical significance relative to control xenografts (30 mg/kg per day, P < 0.05; 50 mg/kg per day, P < 0.05; 70 mg/kg per day, P < 0.01). Increasing concentrations of UDCA led to increased DNA fragmentation observed on gel electrophoresis and in the TUNEL assay (control, 1.6% ± 0.3%; 30 mg/kg per day, 2.9% ± 0.5%; 50 mg/kg per day, 3.15% ± 0.7%, and 70 mg/kg per day, 4.86% ± 0.9%). Western blot analysis revealed increased expression of BAX, APAF1, cleaved-caspase-9 and cleaved-caspase-3 proteins, which induce apoptosis, but decreased expression of BCL2

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

    The objective of this study was to determine which of the following three methods is the most effective for the treatment of bone metastases from hepatocellular carcinoma (HCC): transcatheter arterial embolization (TAE); combination of TAE and external radiotherapy; or external radiotherapy alone. Thirty-nine metastatic bone lesions from HCC in 33 patients were retrospectively reviewed. Each lesion underwent either TAE alone (group A, n=11), TAE followed by radiotherapy (group B, n=17), or radiotherapy alone (group C, n=11). They were evaluated on the following subjects: pain relief; improvement of daily activities; and complications. Each treatment was effective for pain relief (89-94%) and improvement of daily activities (73-82%). The mean time interval from the beginning of each treatment to the onset of initial pain relief was 4.7 days in group A, 4.8 days in group B, and 15 days in group C. Recurrence of the pain after the initial pain relief was noted in 75% in group A, 20% in group B, and 88% in group C. Pyrexia and local pain commonly occurred after TAE. In conclusion, TAE is effective in relieving pain immediately and in improving the patients' daily activities. The combination of TAE and radiotherapy is recommended for permanent pain relief.

    Full Text Available Hepatocellular carcinoma (HCC, one of the most common malignancies with high prevalence and mortality rate, usually results in poor prognosis and limited survival. A comprehensive analysis on the number and location of tumors, Child-Pugh grade, and Barcelona Clinic Liver Cancer stage will help the development of suitable treatment programs and improve prediction of prognosis. A majority of patients are complicated by cirrhosis, enlarged tumor, multiple lesions, vascular invasion, and even cancer embolus in the portal vein. With the growth of knowledge about the radiation tolerance of normal tissue and the advances in radiotherapy techniques, radiotherapy has become an important tool for step-down therapy and adjuvant therapy for liver cancer. Proton beam therapy (PBT is emerging as a novel radiotherapy for the management of HCC, which, benefiting from the effect of Bragg Peak from PBT, effectively decreases the toxicity of traditional radiotherapies to the liver and does little harm to the uninvolved liver tissue or the surrounding structures while intensifying the destruction in targeted malignant lesions. Furthermore, several previous studies on the treatment of HCC with PBT revealed excellent local control. The distinctive biophysical attributes of PBT in the treatment of HCC, as well as the available literature regarding clinical outcomes and toxicity of using PBT for HCC, are reviewed. Current evidence provides limited indications for PBT, which suggests that further study on the relationship between liver function and PBT is required to gain further insight into its indication and standardization.

    Background Our previous investigations have shown that the variants of X-ray repair complementing 4 (XRCC4) may be involved in hepatocellular carcinoma (hepatocarcinoma) tumorigenesis. This study aimed to investigate the possible prognostic significance of XRCC4 expression for hepatocarcinoma patients and possible value for the selection of transarterial chemoembolization (TACE) treatment. Materials and Methods We conducted a hospital-based retrospective analysis (including 421 hepatocarcinoma cases) to analyze the effects of XRCC4 on hepatocarcinoma prognosis and TACE. The levels of XRCC4 expression were tested using immunohistochemistry. The sensitivity of cancer cells to anti-cancer drug doxorubicin was evaluated using the half-maximal inhibitory concentration (IC50). Results XRCC4 expression was significantly correlated with pathological features including tumor stage, liver cirrhosis, and micro-vessel density. XRCC4 expression was an independent prognostic factor of hepatocarcinoma, and TACE treatments had no effects on prognosis of hepatocarcinoma patients with high XRCC4 expression. More intriguingly, TACE improved the prognosis of hepatocarcinoma patients with low XRCC4 expression. Functionally, XRCC4 overexpression increased while XRCC4 knockdown reduced the IC50 of cancer cells to doxorubicin. Conclusions These results suggest that XRCC4 may be an independent prognostic factor for hepatocarcinoma patients, and that decreasing XRCC4 expression may be beneficial for post-operative adjuvant TACE treatment in hepatocarcinoma.

    Hepatocellular carcinoma is the most common primary malignant tumor of the liver, and it is particularly prevalent in East and Southeast Asia. With surgical and/or local interventional treatment methods, survival rates for early-stage hepatocellular cancers have increased. However, it is not yet clear which staging systems are more applicable in hepatocellular carcinoma. Serum albumin level is already being used as a criterion in most staging systems. Albumin is an important serum protein in human bodily functions, but only 5 % of the daily amount needed is synthesized by the liver. The serum albumin level is affected by multifactorial situations, including capillary permeability, drugs, liver insufficiency, inflammation and/or infections, dehydration or overhydration, protein loosing disorders, and decreased nutrition intake in anorexia-malnutrition syndrome and cancer cachexia. Because of this complex situation, serum albumin level may affect many staging systems for hepatocellular carcinoma by leading to false-negative results. In this paper, the statuses of current staging systems are reviewed, and possible negative events regarding the serum albumin levels found in these staging systems are discussed.

    Full Text Available F-box only protein 8 (FBX8, a novel component of F-box proteins, is lost in several cancers and has been associated with invasiveness of cancer cells. However, its expression pattern and role in the progression of hepatocellular carcinoma remain unclear. This study investigated the prognostic significance of FBX8 in hepatocellular carcinoma samples and analyzed FBX8 function in hepatocellular carcinoma cells by gene manipulation.The expression of FBX8 was detected in 120 cases of clinical paraffin-embedded hepatocellular carcinoma tissues, 20 matched pairs of fresh tissues and five hepatocellular carcinoma cell lines by immunohistochemistry with clinicopathological analyses, real-time RT-PCR or Western blot. The correlation of FBX8 expression with cell proliferation and invasion in five HCC cell lines was analyzed. Moreover, loss of function and gain of function assays were performed to evaluate the effect of FBX8 on cell proliferation, motility, invasion in vitro and metastasis in vivo.We found that FBX8 was obviously down-regulated in HCC tissues and cell lines (P<0.05. The FBX8 down-regulation correlated significantly with poor prognosis, and FBX8 status was identified as an independent significant prognostic factor. Over-expression of FBX8 decreased proliferation, migration and invasion in HepG2 and 97H cells, while knock-down of FBX8 in 7721 cells showed the opposite effect. FBX8 negatively correlated with cell proliferation and invasion in 7701, M3, HepG2 and 97H cell lines. In vivo functional assays showed FBX8 suppressed tumor growth and pulmonary metastatic potential in mice. Our results indicate that down-regulation of FBX8 significantly correlates with invasion, metastasis and poor survival in hepatocellular carcinoma patients. It may be a useful biomarker for therapeutic strategy and control in hepatocellular carcinoma treatment.

    Transarterial injection of modified iodized oil was performed in 48 patients with hepatoma. In 41 cases an adriamycin and/or mitomycin C-iodized oil suspension was administered into the proper hepatic artery or peripheral hepatic branches. A reduction in tumor size of over 50% was obtained in 14 of the 33 patients in whom CT examination was performed before and after treatment. Serum alpha-fetoprotein levels decreased in 20 of 21 cases within the first month after injection. The one-year survival rate was estimated at 55% in advanced hepatoma. In 7 patients, transarterial internal irradiation using radioactive iodized oil was carried out. A decrease in tumor size was observed in all cases and in alpha-fetoprotein levels in 6 cases. One patient with severe liver cirrhosis died in hepatorenal failure. No severe complications or other adverse reactions were encountered with either of the methods. (orig.)

Therefore, the imaging criteria for hepatocellular carcinoma (HCC are also usually based on vascular findings, eg, early arterial uptake followed by washout in the portal venous and equilibrium phases. Contrast-enhanced ultrasonography, dynamic multidetector-row computed tomography (MDCT, and dynamic magnetic resonance (MR imaging with gadopentetate dimeglumine (Gd-DTPA are useful for detecting hypervascular HCC on the basis of vascular criteria but are not as useful for hypovascular HCC. Contrast-enhanced MR imaging with gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA, a hepatocyte-specific MR contrast agent, is superior to dynamic MDCT and dynamic MR imaging with Gd-DTPA in detecting both hypervascular and hypovascular HCC. Moreover, Gd-EOB-DTPA-enhanced MR imaging can display each histologically differentiated HCC as hypointense relative to the liver parenchyma. 18F-fluorodeoxyglucose positron emission tomography imaging might not be suitable for the screening and detection of HCC, given its lower diagnostic performance. However, this technique plays an important role in determining whether HCC has spread beyond the liver. Keywords: hepatocellular carcinoma, evaluation, imaging, clinical utility

    Hepatocellular carcinoma is a malignancy that predominantly occurs in the setting of cirrhosis. Its incidence is rising worldwide. Hepatocellular carcinoma differs from most malignancies because it is commonly diagnosed on the basis of imaging features alone, without histologic confirmation. The guidelines from the American Association for the Study of Liver Diseases (AASLD) are a leading statement for the diagnosis and staging of hepatocellular carcinoma, and they have recently been updated, incorporating several important changes. AASLD advocates the use of the Barcelona Clinic Liver Cancer (BCLC) staging system, which combines validated imaging and clinical predictors of survival to determine stage and which links staging with treatment options. Each stage of the BCLC system is outlined clearly, with emphasis on case examples. Focal liver lesions identified at ultrasonographic surveillance in patients with cirrhosis require further investigation. Lesions larger than 1 cm should be assessed with multiphasic computed tomography or magnetic resonance imaging. Use of proper equipment and protocols is essential. Lesions larger than 1 cm can be diagnosed as hepatocellular carcinoma from a single study if the characteristic dynamic perfusion pattern of arterial hyperenhancement and venous or delayed phase washout is demonstrated. If the imaging characteristics of hepatocellular carcinoma are not met, the alternate modality should be performed. Biopsy should be used if neither modality is diagnostic of hepatocellular carcinoma. Once the diagnosis has been made, the cancer should be assigned a BCLC stage, which will help determine suitable treatment options. Radiologists require a systematic approach to diagnose and stage hepatocellular carcinoma with appropriate accuracy and precision.

    Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality and has an increasing incidence worldwide. HCC can be induced by multiple etiologies, is influenced by many risk factors, and has a complex pathogenesis. Furthermore, HCCs exhibit substantial heterogeneity, which compounds the difficulties in developing effective therapies against this highly lethal cancer. With advances in cancer biology and molecular and genetic profiling, a number of different mechanisms involved in the development and progression of HCC have been identified. Despite the advances in this area, the molecular pathogenesis of hepatocellular carcinoma is still not completely understood. This review aims to elaborate our current understanding of the most relevant genetic alterations and molecular pathways involved in the development and progression of HCC, and anticipate the potential impact of future advances on therapeutic drug development.

    CTP synthase (CTPS) can aggregate into an intracellular macrostructure, the cytoophidium, in various organisms including human cells. Previous studies have shown that assembly of human CTPS cytoophidia may be correlated with the cellular metabolic status, and is able to promote the activity of CTPS. A correlation between the cytoophidium and cancer metabolism has been proposed but not yet been revealed. In the current study we provide clear evidence of the presence of CTPS cytoophidia in various human cancers and some non-cancerous tissues. Moreover, among 203 tissue samples of hepatocellular carcinoma, 56 (28%) samples exhibited many cytoophidia, whereas no cytoophidia were detected in adjacent non-cancerous hepatocytes for all samples. Our findings suggest that the CTPS cytoophidium may participate in the adaptive metabolism of human hepatocellular carcinoma. Copyright © 2017. Published by Elsevier Inc.

    Full Text Available Serological markers have the features of noninvasiveness and simple operation and thus have become a research hotspot in the diagnosis of hepatocellular carcinoma. This article briefly introduces the role of the conventional serological marker alpha-fetoprotein (AFP in assisting the diagnosis and predicting the prognosis of HBV-related liver cancer, as well as the clinical value of new markers such as alpha-fetoprotein-L3 and abnormal prothrombin/des-γ-carboxy prothrombin. Based on literature review, the possibility of serum Golgi protein 73 used for laboratory auxiliary diagnosis of hepatocellular carcinoma has been denied. The results of the author′s experiment suggest that serum GP73 measurement can be used as a laboratory diagnostic index for progressive liver fibrosis and liver cirrhosis.

    Full Text Available Sugar intake has dramatically increased during the last few decades. Specifically, there has been a clear trend towards higher consumption of fructose and high fructose corn syrup, which are the most common added sugars in processed food, soft drinks and other sweetened beverages. Although still controversial, this rising trend in simple sugar consumption has been positively associated with weight gain and obesity, insulin resistance and type 2 diabetes mellitus and non-alcoholic fatty liver disease. Interestingly, all of these metabolic alterations have also been related to the development of hepatocellular carcinoma. The purpose of this review is to discuss the evidence coming from epidemiological studies and data from animal models relating the consumption of simple sugars, and specifically fructose, with an increased risk of hepatocellular carcinoma and to gain insight into the putative molecular mechanisms involved.

    Hepatocellular carcinoma (HCC), one of the leading causes of cancer deaths in the world, is offering a challenge to human beings, with the current modes of treatment being a palliative approach. Lack of proper curative or preventive treatment methods encouraged extensive research around the world with an aim to detect a vaccine or therapeutic target biomolecule that could lead to development of a drug or vaccine against HCC. Biomarkers or biological disease markers have emerged as a potential tool as drug/vaccine targets, as they can accurately diagnose, predict, and even prevent the diseases. Biomarker expression in tissue, serum, plasma, or urine can detect tumor in very early stages of its development and monitor the cancer progression and also the effect of therapeutic interventions. Biomarker discoveries are driven by advanced techniques, such as proteomics, transcriptomics, whole genome sequencing, micro- and micro-RNA arrays, and translational clinics. In this review, an overview of the potential of tissue- and serum-associated HCC biomarkers as diagnostic, prognostic, and therapeutic targets for drug development is presented. In addition, we highlight recently developed micro-RNA, long noncoding RNA biomarkers, and single-nucleotide changes, which may be used independently or as complementary biomarkers. These active investigations going on around the world aimed at conquering HCC might show a bright light in the near future. PMID:27398029

    2010-09-01

    Among locoregional treatments for hepatocellular carcinoma (HCC), radiofrequency ablation (RFA) has been accepted as the most popular alternative to curative transplantation or resection, and it shows an excellent local tumor control rate and acceptable morbidity. The benefits of RFA have been universally validated by the practice guidelines of international societies of hepatology. The main advantages of RFA include 1) it is minimally invasive with acceptable morbidity, 2) it enables excellent local tumor control, 3) it has promising long-term survival, and 4) it is a multimodal approach. Based on these pros, RFA will play an important role in managing the patient with early HCC (smaller than 3 cm with fewer than four tumors). The main limitations of current RFA technology in hepatic ablation include 1) limitation of ablation volume, 2) technically infeasible in some tumors due to conspicuity and dangerous location, and 3) the heat-sink effect. Many technical approaches have been introduced to overcome those limitations, including a novel guiding modality, use of artificial fluid or air, and combined treatment strategies. RFA will continue to play a role as a representative ablative modality in the management of HCC, even in the era of targeted agents.

    Full Text Available Hepatocellular carcinoma (HCC is increasingly considered an issue of global importance. Its rates of incidence and mortality have been markedly increasing over the last decades. Among risk factors, some should be highlighted, namely the infections by hepatitis B and C virus, as well as clinical cases of cirrhosis. HCC is characterized as asymptomatic disease in the initial stages which most often leads to a late diagnosis. At molecular and genetic level HCC represents a highly complex tumor entity, including a wide variety of mutations, thus accounting for different mechanisms of resistance towards therapeutic approaches. In particular, mutations of the TP53 gene, as well as a deregulation between the expression of pro- and anti-apoptotic proteins of the BCL-2 family are observed. Regarding treatment modalities, surgical procedures offer the best chance of cure, however, due to a late diagnosis, most of concerned patients cannot be subjected to them. Chemotherapy and radiotherapy are also ineffective, and currently, the treatment with sorafenib is the most commonly used systemic therapy although it can only increase the patient survival for some months. In this sense, a quick and accurate investigation is of utmost importance in order to develop ways of early diagnosis as well as new therapies for HCC.

    The aim of the present study was to investigate the effects of regorafenib on hepatocellular carcinoma autophagy, thereby supressing the malignancy of HCC. First, HepG2 and Hep3B cell autophagy was investigated using GFP-LC3 transfection after the treatment of regorafenib. Then, the activation of Akt/mTOR signaling was analyzed using western blot. Our data showed that liver cancer cell autophagy was significantly induced by 20 μM regorafenib using GFP-LC3 transfection. Meanwhile, regorafenib-induced cell death could largely be abolished by 3-MA or CQ treatment, suggesting that regorafenib-induced HepG2 cell death was partially dependent on autophagy. Moreover, the activation of Akt/mTOR signaling was inhibited by regorafenib pre-incubation. MTT assay showed the combination use of regorafenib and CDDP led to a stronger growth inhibitory effect on HepG2 and Hep3B cells. In summary, regorafenib may acts an adjunctive therapy for liver cancer patients via modulating autophagy-dependent cell death even when apoptosis resistance is induced in cancer cells.

    Full Text Available Background: The aim of this study was to characterize the disorder of lipid metabolism in hepatocellular carcinoma (HCC. HCC is a worldwide disease. The research into the disorder of lipid metabolism in HCC is very limited. Study of lipid metabolism in liver cancer tissue may have the potential to provide new insight into HCC mechanisms. Methods: A lipidomics study of HCC based on Ultra high performance liquid chromatography-electronic spray ionization-QTOF mass spectrometer (UPLC-ESI-QTOF MS and Matrix assisted laser desorption ionization-fourier transform ion cyclotron resonance mass spectrometer (MALDI-FTICR MS was performed. Results: Triacylglycerols (TAGs with the number of double bond (DB > 2 (except 56:5 and 56:4 TAG were significantly down-regulated; conversely, others (except 52:2 TAG were greatly up-regulated in HCC tissues. Moreover, the more serious the disease was, the higher the saturated TAG concentration and the lower the polyunsaturated TAG concentration were in HCC tissues. The phosphatidylcholine (PC, phosphatidylethanolamine (PE and phosphatidylinositol (PI were altered in a certain way. Sphingomyelin (SM was up-regulated and ceramide (Cer were down-regulated in HCC tissues. Conclusions: To our knowledge, this is the first such report showing a unique trend of TAG, PC, PE and PI. The use of polyunsaturated fatty acids, like eicosapentanoic and docosahexanoic acid, as supplementation, proposed for the treatment of Non-alcoholic steatohepatitis (NASH, may also be effective for the treatment of HCC.

    To evaluate the effect of radiotherapy (RT) on hepatocellular carcinoma (HCC) that appears as a solitary nodule on radiologic studies. We irradiated 17 patients with solitary HCC lesions (25-150 mm in diameter) with approximately 60 Gy (range 50-70 Gy). Patients underwent dynamic CT and/or ultrasound imaging at 3-month intervals after treatment. Patients were classified based on lesion size, degree of cirrhosis (Child A. 6; Child B, 6; Child C, 5), and whether they had received other therapy such as transarterial chemoembolization (TACE). The responses were classified as complete, partial, no change, or progression. The median survival was 12.8 months for all 17 patients, with 1-, 2-, and 3-year cumulative survival rates of 59%, 35% and 24%, respectively. Patients classified as Child A showed significantly longer survival than those classified as either Child B (p<0.04) or C (p<0.01). Four of the five Child C patients died of liver failure within 6 months after RT despite the absence of tumor recurrence. The initial tumor diameter, concurrent treatment with TACE, and radiation dose showed no significant effect on survival. Survival in patients with solitary HCC lesions appears to be affected mainly by the degree of liver dysfunction, and not the initial tumor diameter, radiation dose, or concurrent use of TACE.

    Full Text Available Background: Transarterial chemoembolization is the preferred treatment for unresectable, intermediate-stage hepatocellular carcinoma. Survival after transarterial chemoembolization can be highly variable. The purpose of this study is to identify the factors that predict overall survival of patients with unresectable hepatocellular carcinoma who undergo transarterial chemoembolization as the initial therapy. Methods:We included patients who underwent transarterial chemoembolization from 2007 to 2012 in this study. Patient’s age, gender, cause of cirrhosis, Child-Turcotte-Pugh score, model of end-stage liver disease score, Cancer of the Liver Italian Program score, Okuda stage, alpha- fetoprotein level, site, size and number of tumors were recorded. Radiological response to transarterial chemoembolization was assessed by computerized tomography scan at 1 and 3 months after the procedure. Repeat sessions of transarterial chemoembolization were performed according to the response. We performed survival assessment and all patients were assessed for survival at the last follow-up. Results: Included in this study were 71 patients of whom there were 57 (80.3 % males, with a mean age of 51.9±12.1 years (range: 18-76 years. The mean follow-up period was 12.5±10.7 months. A total of 31 (43.7% patients had only one session of transarterial chemoembolization, 17 (23.9% underwent 2 and 11 (15.5% had 3 or more sessions. On univariate analysis, significant factors that predicted survival included serum bilirubin (P=0.02, esophageal varices (P=0.002, Cancer of the Liver Italian Program score (P=0.003, tumor size (P=0.005, >3 sessions of transarterial chemoembolization (P=0.006 and patient's age (P=0.001. Cox regression analysis showed that tumor size of 1 transarterial chemoembolization session (P=0.004 were associated with better survival. Conclusion: Our study demonstrates that survival after transarterial chemoem- bolization is predicted by tumor size

  11. Hepatitis infections, aflatoxin and hepatocellular carcinoma

    Full Text Available

    The incidence rates of hepatocellular carcinoma (HCC show large geographic variations, globally reflecting the prevalence of two main aetiologic factors, hepatitis B (HBV and/or C (HCV virus infection and exposure to high levels of aflatoxin in the diet (Chen et al. 1997. The highest incidence rates are observed in regions where most of the population is exposed to both factors, such as in parts of eastern Asia and in sub-Saharan Africa (Parkin et al. 2001. These high incidences are consistent with the fact that HBV chronicity and exposure to aflatoxin have a multiplicative effect of risk for HCC. Depending on aetiology and geographic area, mutations in TP53 show striking differences in prevalence and pattern. In Europe and the US, where alcohol is a major risk factor in addition to viral infections, mutations occur in about 25% of HCC and show as much diversity in their type and codon position as in most other epithelial cancers. However, in high incidence areas such as Mozambique, Senegal, The Gambia (Africa and Qidong county (China, TP53 is mutated in over 50% of the cases and the vast majority of these mutations are a single missense, hotspot mutation at codon 249, AGG to AGT, resulting in the substitution of arginine into serine (249ser. This mutation is uncommon in regions where aflatoxin is not present at significant levels in the diet. In areas of intermediate exposure to aflatoxin, as for example in Thailand, the prevalence of the 249ser mutation is intermediate between high- and low-incidence areas. Thus, there is a dose-dependent relationship between exposure to aflatoxin, incidence of HCC and prevalence of 249ser mutation. Aflatoxins are toxic and carcinogenic metabolites produced by several varieties of molds, mainly Aspergillus flavus and Aspergillus parasiticum. These molds contaminate a wide range of traditional agricultural products in countries

    Rationale of this study was framed to investigate the protective effect and anti-cancer property of nanoparticles based on chitosan isolated from squid, Sepioteuthis lessoniana, on hepatic cells in N-Nitrosodiethylamine-induced hepatocellular carcinoma in rats. The results conferred that the chitosan nanoparticle supplementation had a protective effect on liver cells by reducing the levels of marker enzymes and bilirubin and thus increasing the albumin levels. The level of reduced glutathione, ascorbic acid and α-tocopherol significantly increased in both post- and pre-treatment with chitosan nanoparticles. The levels of antioxidant enzymes were enhanced and lipid peroxidation products were diminished while treating nitrosodiethylamine-induced hepatocellular carcinoma with chitosan nanoparticles. Supplementation of chitosan nanoparticles had potent anti-hyperlipidemic property that was evidenced by monitoring the serum lipid levels and its components. Animals pre-treated with chitosan nanoparticles along with nitrosodiethylamine showed a significant reduction in the total cholesterol and triglycerides levels with increase in the levels of phospholipids and free fatty acids. Chitosan nanoparticles treated rats showed significant increment in high-density lipoprotein cholesterol and reduction in low-density lipoprotein and very low-density lipoprotein cholesterol when compared with levels in nitrosodiethylamine-induced hepatocellular carcinoma. Nitrosodiethylamine-induced carcinoma changes on circulation and hepatic antioxidant defense mechanism were regulated by chitosan nanoparticles, concluding that the chitosan nanoparticles have a potent protective effect on liver cells which might be due to its robust antioxidant and anti-lipidemic property.

    Full Text Available Cisplatin (CisPt is a commonly used platinum-based chemotherapeutic agent. Its efficacy is limited due to drug resistance and multiple side effects, thereby warranting a new approach to improving the pharmacological effect of CisPt. A newly developed mathematical hypothesis suggested that mechanical loading, when coupled with a chemotherapeutic drug such as CisPt and immune cells, would boost tumor cell death. The current study investigated the aforementioned mathematical hypothesis by exposing human hepatocellular liver carcinoma (HepG2 cells to CisPt, peripheral blood mononuclear cells, and mechanical stress individually and in combination. HepG2 cells were also treated with a mixture of CisPt and carnosine with and without mechanical stress to examine one possible mechanism employed by mechanical stress to enhance CisPt effects. Carnosine is a dipeptide that reportedly sequesters platinum-based drugs away from their pharmacological target-site. Mechanical stress was achieved using an orbital shaker that produced 300 rpm with a horizontal circular motion. Our results demonstrated that mechanical stress promoted CisPt-induced death of HepG2 cells (~35% more cell death. Moreover, results showed that CisPt-induced death was compromised when CisPt was left to mix with carnosine 24 hours preceding treatment. Mechanical stress, however, ameliorated cell death (20% more cell death.

    This study aimed to evaluate the initial outcomes of proton beam therapy (PBT) for hepatocellular carcinoma (HCC) in terms of tumor response and safety. HCC patients who were not indicated for standard curative local modalities and who were treated with PBT at Samsung Medical Center from January 2016 to February 2017 were enrolled. Toxicity was scored using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Tumor response was evaluated using modified Response Evaluation Criteria in Solid Tumors (mRECIST). A total of 101 HCC patients treated with PBT were included. Patients were treated with an equivalent dose of 62-92 GyE 10 . Liver function status was not significantly affected after PBT. Greater than 80% of patients had Child-Pugh class A and albumin-bilirubin (ALBI) grade 1 up to 3-months after PBT. Of 78 patients followed for three months after PBT, infield complete and partial responses were achieved in 54 (69.2%) and 14 (17.9%) patients, respectively. PBT treatment of HCC patients showed a favorable infield complete response rate of 69.2% with acceptable acute toxicity. An additional follow-up study of these patients will be conducted.

    The clinical management of hepatocellular carcinoma has evolved greatly in the last decade mostly through recent technical innovations. In particular, the application of cutting-edge image guidance has led to minimally invasive solutions for complex clinical problems and rapid advances in the field of interventional oncology. Many image-guided therapies, such as transarterial chemoembolization and radiofrequency ablation, have meanwhile been fully integrated into interdisciplinary clinical practice, whereas others are currently being investigated. This review summarizes and evaluates the most relevant completed and ongoing clinical trials, provides a synopsis of recent innovations in the field of intraprocedural imaging and tumor response assessment, and offers an outlook on new technologies, such as radiopaque embolic materials. In addition, combination therapies consisting of locoregional therapies and systemic molecular targeted agents (e.g., sorafenib) remain of major interest to the field and are also discussed. Finally, we address the many substantial advances in immune response pathways that have been related to the systemic effects of locoregional therapies. Knowledge of these new developments is crucial as they continue to shape the future of cancer treatment, further establishing interventional oncology along with surgical, medical, and radiation oncology as the fourth pillar of cancer care.

    CC chemokine receptor 1 (CCR1) has an important role in the recruitment of leukocytes to the site of inflammation. The migration and metastasis of tumor cells shares many similarities with leukocyte trafficking, which is mainly regulated by chemokine receptor-ligand interactions. CCR1 is highly expressed in hepatocellular carcinoma (HCC) cells and tissues with unknown functions. In this study, we silenced CCR1 expression in the human HCC cell line HCCLM3 using artificial microRNA (miRNA)-mediated RNA interference (RNAi) and examined the invasiveness and proliferation of CCR1-silenced HCCLM3 cells and the matrix metalloproteinase (MMP) activity. The miRNA-mediated knockdown expression of CCR1 significantly inhibited the invasive ability of HCCLM3 cells, but had only a minor effect on the cellular proliferation rate. Moreover, CCR1 knockdown significantly reduced the secretion of MMP-2. Together, these findings indicate that CCR1 has an important role in HCCLM3 invasion and that CCR1 might be a new target of HCC treatment

    Adrenal metastases (AM) from hepatocellular carcinoma (HCC) are rarely seen in clinical practice. The treatment is not standardized, the indications and efficacy of different therapeutic approaches being still controversial. Between January 1995 and December 2005, 174 patients underwent liver resection for HCC in our center. AM were detected in four patients (2.3%): three of them had HCC and synchronous AM, and the remaining one developed AM 10 months after liver resection. All the patients with AM were treated by adrenalectomy (simultaneously with liver resection in synchronous metastases), followed by systemic chemotherapy. Non-resectable multifocal liver recurrences occurred in two patients, one of them having also a contralateral adrenal metastasis; these two patients are presently alive 26 and 43 months after adrenalectomy, respectively. Another patient died by liver recurrence 27 months postoperatively. The fourth patient is disease-free at 17 months after the initial operation. Adrenalectomy for AM from HCC should be performed whenever the primary tumor is well therapeutically controlled and the patient has a good performance status. Adrenalectomy offers the chance of more than 2 years survival in many patients. However, once AM are detected, the prognosis remains poor.

    Full Text Available Hepatocellular carcinoma (HCC is the sixth most common cancer and the third leading cause of cancer-related deaths in the world. The Barcelona Clinic Liver Cancer (BCLC classification has recently emerged as the standard classification system for clinical management of patients with HCC. According to the BCLC staging system, curative therapies (resection, transplantation, and percutaneous ablation can improve survival in HCC patients diagnosed at an early stage and offer potential long-term curative effects. Patients with intermediate-stage HCC benefit from transcatheter arterial chemoembolization (TACE, and those diagnosed at an advanced stage receive sorafenib, a multikinase inhibitor, or conservative therapy. Most patients receive palliative or conservative therapy only, and approximately 50% of patients with HCC are candidates for systemic therapy. TACE is often recommended for advanced-stage HCC patients all over the world because these patients desire therapy that is more effective than systemic chemotherapy or conservative treatment. This paper aims to summarize both the published data and important ongoing studies for TACE and to discuss technical improvements in TACE for advanced-stage HCC.

    Hepatocellular carcinoma (HCC) ranks second amongst all causes of cancer deaths globally. It is on a rise in Pakistan and might represent the most common cancer in adult males. Pakistan contributes significantly to global burden of hepatitis C, which is a known risk factor for HCC, and has one of the highest prevalence rates (>3%) in the world. In the absence of a national cancer registry and screening programs, prevalence of hepatitis and HCC only represents estimates of the real magnitude of this problem. In this review, we present various aspects of HCC in Pakistan, comparing and contrasting it with the global trends in cancer care. There is a general lack of awareness regarding risk factors of HCC in Pakistani population and prevalence of hepatitis C has increased. In addition, less common risk factors are also on a rise. Majority of patients present with advanced HCC and are not eligible for definitive treatment. We have attempted to highlight issues that have a significant bearing on HCC outcome in Pakistan. A set of strategies have been put forth that can potentially help reduce incidence and improve HCC outcome on national level. PMID:26955390

    Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death, especially in Eastern areas. With advancements in diagnosis and treatment modalities for HCC, the survival and prognosis of HCC patients are improving. However, treatment patterns are not uniform between areas despite efforts to promote a common protocol. Although many hepatologists in Asian countries may adopt the principles of the Barcelona Clinic Liver Cancer staging system, they are also independently making an effort to expand the indications of each treatment and to combine therapies for better outcomes. Several expanded criteria for liver transplantation in HCC have been developed in Asian countries. Living donor liver transplantation is much more commonly performed in these countries than deceased donor liver transplantation, and it may be preceded by other treatments such as the down-staging of tumors. Local ablation therapies are often combined with transarterial chemoembolization (TACE) and the outcome is comparable to that of surgical resection. The indications of TACE are expanding, and there are new types of transarterial therapies. Although data on drug-eluting beads, TACE, and radioembolization in Asian countries are still relatively sparse compared with Western countries, these methods are gradually gaining popularity because of better tolerability and the possibility of improved response rates. Hepatic arterial infusion chemotherapy and radiotherapy are not included in Western guidelines, but are currently being used actively in several Asian countries. For more advanced HCCs, appropriate combinations of TACE, radiotherapy, and sorafenib can be considered, and emerging data indicate improved outcomes of combination therapies compared with single therapies. To include these paradigm shifts into newer treatment guidelines, more studies may be needed, but they are certainly in progress. PMID:25852267

    Full Text Available Abstract Background Glucose regulated protein 78 (Grp78 is involved in the invasion and metastasis in many human cancers including gastric cancer, breast cancer, prostate cancer. But the role of Grp78 in the invasion of human hepatocellular carcinoma has not been reported. In this article, we examined if Grp78 was associated with the invasion of hepatocellular carcinoma and explored the possible underlying mechanism. Methods The Grp78 and FAK expression levels in 44 patients with hepatocellular carcinoma were examined using immunohistochemistry. Grp78 overexpressing SMMC7721 cells were established by pcDNA3.1 (+-Grp78 transfection and screened by G418. Grp78 and FAK levels in Grp78 overexpressing cells were down-regulated by siRNA transfection. The invasion status of tumor cells was evaluated by transwell assay in vitro, and chick embryo metastasis model in vivo. Cell spreading was determined by cell spreading assay, and quantitatively measured by Orisis software HUG. Grp78, pY397 FAK, pY576/577 FAK and FAK levels were detected by western blot. RhoA activity was detected by GST pulldown assay. The distribution of actin cytoskeleton was observed by fluorescent staining. Results Grp78 expression levels in 44 patients with hepatocellular carcinoma were negatively correlated with tumor grading, and positively correlated with portal invasion and intra-hepatic invasion. Overexpression of Grp78 in SMMC7721 cells promoted the invasion of cancer cells in vitro and in vivo, and this increase in tumor cell invasion was blocked by Grp78 siRNA knockdown. Our results also revealed that overexpression of Grp78 in SMMC7721 cells accelerated the process of cell spreading and promoted lamellipodia formation. Further analysis showed that overexpression of Grp78 in SMMC7721 cells increased pY397 and pY576/577 levels of FAK. Grp78 siRNA knockdown decreased FAK activation and activity. Our results also revealed that Grp78 overexpression in SMMC7721 cells decreased

    Liver has a dual blood supply from portal vein and hepatic artery. Hepatocellular carcinoma receive their blood supply almost exclusively from hepatic artery. Thus, the concept of treating hepatocellular carcinoma by chemoembolization through these arteries is very effective . However, there may be several collateral or parasitic vessels feeding them in case of huge tumor or previous chemoembolization. We experienced a case of huge tumor involving right upper posterior portion of liver fed by 9th, 10th, 11th right posterior intercostal arteries and an anomalous hepatic artery. We tried chemoembolization with Adriamycin-Lipiodol suspension and Gelfoam material through the right posterior intercostal arteries to treat the lesion. After the procedure, the patient(55 years old female) became paraplegic with voiding and defecation difficulty which could be due to spinal cord infarction by anterior spinal arterial occlusion caused by embolic material through the artery of Adamkiewicz from a posterior intercostal artery. She recovered completely after 20 days of treatment

    A 60-year-old male patient who previously underwent transarterial chemoembolization for recurrent hepatocellular carcinoma three months ago presented to the emergency department with pleural effusion and hemoptysis. On serial review of plain radiographs and chest CT, transdiaphragmatic migration of Lipiodol from the treated area of the liver into the ipsilateral pleural cavity was demonstrated. The patient consequently developed empyema in the right thorax. Therefore, percutaneous drainage was performed. Empyema and pleural effusion regressed after 10 days of medical treatment and drainage. After that, the patient was transferred back to the local clinic upon full symptomatic recovery. Herein, we describe a rare complication of transarterial chemoembolization for hepatocellular carcinoma manifesting as an empyema secondary to the migration of the ethiodized oil content from the liver into the ipsilateral pleural cavity.

    MicroRNAs are involved in hepatocellular carcinoma metastasis, a principal cause of hepatocellular carcinoma-related death in patients worldwide. MiR-212 is a microRNA that has been identified in several types of cancers and is postulated to influence cell signaling and subsequent malignant pathogenesis. Despite emerging reports suggesting that miR-212 plays a significant role in the onset, progression, and migration of these types of malignant tumors, its involvement in the development of hepatocellular carcinoma has not been fully elucidated. Quantitative reverse transcription polymerase chain reaction, wound healing, transwell migration and invasion assays, Western blotting, and xenograft tumor growth models were performed to test the expression levels and functions of miR-212 in hepatocellular carcinoma. Luciferase reporter assay, quantitative reverse transcription polymerase chain reaction, Western blotting, and immunohistochemistry were used to identify and verify the target of miR-212. In this study, we identify significant repression of miR-212 in hepatocellular carcinoma and demonstrate that overexpression of miR-212 inhibits the migration of hepatocellular carcinoma cells in vitro and in vivo. Furthermore, we identify forkhead box M1, whose expression is inversely related to that of miR-212, as a direct target of miR-212. Additionally, reexpression of forkhead box M1 rescues the miR-212-mediated inhibition of cell migration. We observed that inhibition of miR-212 activates forkhead box M1 but inhibits the Wnt/β-catenin pathway by suppressing Wnt, LEF-1, c-Myc, and nuclear β-catenin. Finally, in vivo studies confirmed the inhibitory effect of miR-212 on hepatocellular carcinoma growth. Our present findings indicate that miR-212 is a potential prognostic biomarker of hepatocellular carcinoma and that the miR-212/forkhead box M1 regulatory axis may represent a new therapeutic objective for hepatocellular carcinoma treatment.

    Leptomeningeal metastasis, which results from metastasis of tumors to the arachnoid and pia mater, can lead to the dissemination of tumor cells throughout the subarachnoid space via the cerebral spinal fluid, and frequently with a poor prognosis. The primary tumor in adults is most often breast cancer, lung cancer, or melanoma. Although leptomeningeal metastasis due to cholangiocarcinoma has been reported, to the best of our knowledge there is no cytologically confirmed report of leptomeningeal metastasis from hepatocellular carcinoma. We herein report a case of leptomeningeal metastasis from hepatocellular carcinoma in a 53-year-old woman with concomitant systemic metastases to the lung, bone, brain, kidney, adrenal gland, subcutaneous tissues, and abdominal pelvis. The neurological symptoms of the patient were relieved after treatment with methotrexate intra-cerebral spinal fluid chemotherapy concurrent with whole brain radiotherapy. To our knowledge this is the first report of leptomeningeal metastasis from hepatocellular carcinoma confirmed by cytology. Treatment with methotrexate intra-cerebral spinal fluid chemotherapy concurrent with whole brain radiotherapy was effective

    Hook1 is a member of the hook family of coiled-coil proteins, which is recently found to be associated with malignant tumors. However, its biological function in hepatocellular carcinoma is yet unknown. Here, we evaluated the Hook1 levels in human hepatocellular carcinoma samples and matched peritumoral tissues by real-time polymerase chain reaction. Small interfering RNA knockdown and a transforming growth factor-β-induced epithelial-mesenchymal transition model were employed to investigate the biological effects of Hook1 in hepatocellular carcinoma. Our results indicated that Hook1 levels were significantly lower in hepatocellular carcinoma tissues than in the peritumoral tissues. In addition, Hook1 expression was significantly associated with hepatocellular carcinoma malignancy. Hook1 was downregulated after transforming growth factor-β-induced epithelial-mesenchymal transition. Moreover, Hook1 knockdown promoted epithelial-mesenchymal transition and attenuated the sensitivity of hepatocellular carcinoma cells to doxorubicin. In summary, our results indicate that downregulation of Hook1 plays a pivotal role in hepatocellular carcinoma progression via epithelial-mesenchymal transition. Hook1 may be used as a novel marker and therapeutic molecular target in hepatocellular carcinoma.

    We followed for 2 years patients treated with Direct Acting Agents (DAA) to assess long-term durability of virologic response, improvement of liver function, reduction of liver stiffness (LS), and risk of hepatocellular carcinoma (HCC).The study included patients from 16 hepatologic centers involved in the AMBER, investigators initiated study on treatment of chronic hepatitis C patients within a programme preceding EU registration of Ombitasvir/Paritaprevir/ritonavir±Dasabuvir±Ribavirin. A total of 204 patients among 209 from the primary study were enrolled; 200 with available testing at 2 years follow-up (2yFU) with undetectable HCV RNA (198 responders and 2 non-responders retreated). During 2yFU 4 patients died, 17 had hepatic decompensation and 3 needed liver transplantation. De novo hepatocellular carcinoma was diagnosed in 4 and its recurrence in 3 patients. Significant decreases in bilirubin, MELD, Child-Pugh scores and liver stiffness, and increases in albumin level were observed during 2yFU. Strengths of the study were a fixed period of post treatment follow-up, prospective character of the study and high proportion of available patients from the primary study. The major weaknesses was lack of a comparative arm and relatively insufficient number of patients for subsets analysis. In conclusion, two-years follow-up confirmed durability of virologic response after treatment of HCV infection with Ombitasvir/Paritaprevir/ritonavir±Dasabuvir±Ribavirin. It was accompanied by significant improvement of major measures of hepatic function and reduction of hepatic stiffness. Successful therapy did not prevent hepatic decompensation, HCC or death in cirrhotics, that support the need for longer than 2-year monitoring for possible disease progression.

    Full Text Available Tatsuo Kanda, Osamu Yokosuka Department of Gastroenterology and Nephrology, Chiba University, Graduate School of Medicine, Chiba, Japan Abstract: Hepatocellular carcinoma (HCC is one of the male-dominant liver diseases with poor prognosis, although treatments for HCC have been progressing in the past decades. Androgen receptor (AR is a member of the nuclear receptor superfamily. Previous studies reported that AR was expressed in human HCC and non-HCC tissues. AR is activated both ligand-dependently and ligand-independently. The latter is associated with a mitogen-activated protein kinase–, v-akt murine thymoma viral oncogene homolog 1–, or signal-transducer and activator of transcription–signaling pathway, which has been implicated in the development of HCC. It has been reported that more than 200 RNA expression levels are altered by androgen treatment. In the liver, androgen-responsive genes are cytochrome P450s, transforming growth factor , vascular endothelial growth factor, and glucose-regulated protein 78 kDa, which are also associated with human hepatocarcinogenesis. Recent studies also revealed that AR plays a role in cell migration and metastasis. It is possible that cross-talk among AR-signaling, endoplasmic reticulum stress, and innate immune response is important for human hepatocarcinogenesis and HCC development. This review shows that AR could play a potential role in human HCC and represent one of the important target molecules for the treatment of HCC. Keywords: vascular endothelial growth factor, angiogenesis, glucose-regulated protein 78 kDa, hepatocarcinogenesis, molecular targets

    Stereotactic body radiotherapy (SBRT) has been shown to improve overall survival in patients with advanced hepatocellular carcinoma. This study aimed to assess the cost-effectiveness of SBRT compared to sorafenib which is the only drug for advanced hepatocellular carcinoma. A Markov decision-analytic model was performed to compare the cost-effectiveness of SBRT and sorafenib for unresectable advanced hepatocellular carcinoma. Patients transitioned between three health states: stable disease, progression disease and death. We calculated the data on cost from the perspective of our National Health Insurance Bureau. Sensitivity analyses were conducted to determine the impact of several variables. The incremental cost effectiveness ratio (ICER) for sorafenib compared to SBRT was NT$3,788,238 per quality-adjusted life year gained (cost/QALY), which was higher than the willingness to pay threshold of Taiwan according to WHO’s guideline. One-way sensitivity analysis revealed that the utility of progression disease for the sorafenib treatment, utility of progression free survival for SBRT, utility of progression free survival for sorafenib, utility of PFS to progression disease for SBRT and transition probability of progression disease to dead for SBRT were the most sensitive parameters in all cost scenarios. The Monte-Carlo simulation demonstrated that the probability of cost-effectiveness at a willingness to pay threshold of NT$ 2,213,145 per QALY was 100 % and 0 % chance for SBRT and sorafenib. This study indicated that SBRT for advanced hepatocellular carcinoma is cost-effective at a willingness to pay threshold as defined by WHO guideline in Taiwan

    Bile salts containing vesicles (bilosomes) represent a portentous vesicular carrier that showed prosperous results in delivering active moieties in the gastrointestinal tract (GIT). In this study, bilosomes were exploited to deliver sulfated polysaccharide-protein complexes of Enteromorpha intestinalis (EHEM) and enhance its activity against hepatocellular carcinoma as well as resist harsh GIT conditions. Bilosomes were prepared using the sodium salt of three different bile acids (cholic, deoxycholic, taurodeoxycholic) and two different nonionic surfactants (Span 40 and 65). The effects of experimental variables were thoroughly studied to obtain an optimum formulation loading EHEM. The selected formulation (EH-Bilo-2) prepared with sodium cholate and Span 65 displayed nano-sized (181.1 ± 16.80 nm) spherical vesicles with reasonable entrapment efficiency (71.60 ± 0.25%) and controlled release properties; and thus was investigated as anti-hepatocarcinogenic candidate for in vivo studies. Treatment of hepatocellular carcinoma (HCC) bearing rats with EH-Bilo-2 experienced significant decrease in serum α-fetoprotein, endoglin, lipocalin-2, and heat shock protein 70 levels vs. the untreated counterparts. Furthermore, the photomicrographs of their liver tissue sections showed focal area of degenerated pleomorphic hepatocytes with fine fibrosis originating from the portal area. Thus, the optimized bilosomal formulation is a promising delegate for tackling hepatocellular carcinoma owing to its powerful anti-cancer and anti-angiogenic activity.

    Objective: The aim of this study was to determine the effectiveness and safety of percutaneous laser ablation for the treatment of cirrhotic patients with hepatocellular carcinoma awaiting liver transplantation. Materials and methods: The data of 9 male cirrhotic patients (mean age 50 years, range 45-60 years) with 12 biopsy proven nodules of hepatocellular carcinoma (mean diameter 2.0 cm, range 1.0-3.0 cm) treated by laser ablation before liver transplantation between June 2000 and January 2006 were retrospectively reviewed. Laser ablation was carried out by inserting 300 nm optical fibers through 21-Gauge needles (from two to four) positioned under ultrasound guidance into the target lesions. A continuous wave Neodymium:Yttrium Aluminium Garnet laser was used. Transarterial chemoembolization prior to liver transplantation was performed in two incompletely ablated tumors. Results: No procedure-related major complications were recorded. During the waiting time to liver transplantation local tumor progression after ablation occurred in 3 nodules (25%). At histological examination of the explanted livers complete necrosis was found in 8 nodules (66.7%, all treated exclusively with laser ablation), partial necrosis >50% in 3 nodules (25%), and partial necrosis <50% in 1 nodule. Conclusion: In patients with cirrhotic livers awaiting liver transplantation, percutaneous laser ablation is safe and effective for the management of small hepatocellular carcinoma.

  17. Usefulness of Pure Laparoscopic Hepatectomy for Hepatocellular Carcinoma in a Severely Cirrhotic Patient

    Full Text Available The number of patients undergoing laparoscopic hepatectomy has rapidly increased in recent years, and indications for this procedure are gradually expanding. Pure laparoscopic hepatectomy is reportedly useful in cases with severe liver cirrhosis. A 55-year-old woman under observation for liver cirrhosis was found to have hepatocellular carcinoma in liver segment III and was referred to our hospital for surgery. The tumor was located in the edge of liver segment III, where percutaneous ablation therapy was unsuitable. Since her hepatic functional reserve was poor, pure laparoscopic partial hepatectomy was performed. The postoperative course was favorable, with no ascites retention, edema or weight gain. The greatest advantage of pure laparoscopic hepatectomy for hepatocellular carcinoma with concomitant liver cirrhosis is that postoperative ascites retention is minimal, meaning that there is little risk of water-electrolyte imbalance associated with ascites retention or hypoproteinemia. This is believed to be because the abdominal incision is small and mobilization of the liver is minimized, reducing the destruction of the routes of collateral lymph flow and blood flow generated in patients with liver cirrhosis. Pure laparoscopic hepatectomy may be a treatment choice for patients with hepatocellular carcinoma and concomitant severe liver cirrhosis.

    To evaluate patterns of recurrence and factors which influence them in radiofreqency (RF) ablation for the treatment of hepatocellular carcinoma (HCC). Between May 1999 and March 2000, 69 patients with 82 HCCs underwent RF ablation for complete necrosis. They were diagnosed by tissue biopsy or tumor marker, and the results of triphasic spiral CT. The indications were that nodular lesions were clearly visualized at sonography, less than 5 cm in size and less than four in number, and that patients had no history of previous treatment. Local therapeutic efficacy such as complete necrosis and marginal recurrence, and new lesions were evaluated by means of triphasic spiral CT performed at least six months after the completion of ablation. We then analyzed the correlation between local therapeutic efficacy and various influential factors such as tumor size, whether the tumor was attached to the portal vein, gross morphology, Child-Pugh classification, and {alpha}-fetoprotein level vefore the procedure, as well as the correlation between new lesions and influential factors which included the {alpha}-fetoprotein level before the procedure, Child-Pugh classification, and multiplicity per person. During a mean follow-up period of 8.95 (range, 6-14) months after RF ablation, the rate of complete necrosis and of marginal recurrence was 91% and 12%, respectively. When a tumor was larger and was attached to a large branch of the portal vien, the incidence of incomplete necrosis and marginal recurrence was greater. The occurrence rate of new lesion was 19.4%. When the {alpha}-fetoprotein level before the procedure was higher and a tumor was multiple in number, new lesions occurred more frequently. Sufficient knowledge of patterns of recurrence and the factors which influence them might improve the therapeutic effects of RF ablation in patients with HCC.

    The survival of patients with unresectable advanced hepatocellular carcinoma (HCC) with portal vein thrombosis is dismal. Current therapeutic options have limited efficacy. Vitamin K has been shown to have antitumor effect on HCC cells both in cell lines and patients with advanced HCC. The aim of this study was to assess the clinical efficacy of high dose vitamin K3 in the treatment of advanced HCC with portal vein thrombosis. Forty-two consecutive patients with advanced HCC (Stage C according to BCLC staging system) with portal vein thrombosis were randomized into two groups: (i) high dose vitamin K3 (n = 23); and (ii) placebo (n = 19). The vitamin K3 was administered by i.v. infusion of 50 mg/day with daily increase of dose by 50 mg for 6 days, followed by 20 mg i.m. twice daily for 2 weeks. Of the 23 patients treated with vitamin K, one (4.3%) achieved complete response and three (13%) partial response, for a total of four (17.4%) objective responders overall. The overall mean survival was 8.9 +/- 8.8 months (median: 6; range 1-37 months) in the vitamin K group and 6.8 +/- 5.3 months (median: 5; range 1.5-21 months) in the placebo group (P = 0.552). The mean duration of survival was longer in patients in the vitamin K group who achieved objective response (22.5 +/- 12.2; median: 21; range 11-37 months) as compared to patients not achieving objective response (6.1 +/- 4.6; median: 5; range 1-16 months) (P = 0.0.002). Portal vein thrombosis resolved with complete patency in one (4.35%) patient. Treatment with high dose vitamin K produces objective response in 17% patients with improved survival in patients achieving objective response; however, it does not affect the overall survival.

In this regard, tumor size is one of the two main prognostic factors for surgical resection, which constitutes the only curative treatment for HCC along with liver transplantation. However, techniques for HCC surveillance and diagnosis that are currently used in clinical practice have certain limitations that may be inherent to the tumor development. Thus, it is important to continue efforts in the search for biomarkers that increase diagnostic accuracy for HCC. In this review, we focus on different biological sources of candidate biomarkers for HCC diagnosis. Although those biomarkers identified from biological samples obtained by noninvasive methods have greater diagnostic value, we have also considered those obtained from liver tissue because of their potential therapeutic value. To date, sorafenib is the only US Food and Drug Administration-approved antineoplastic for HCC. However, this therapeutic agent shows very low tumor response rates and frequently causes acquired resistance in HCC patients. We discuss the use of HCC biomarkers as therapeutic targets themselves, or as targets to increase sensitivity to sorafenib treatment. Keywords: diagnosis, sorafenib, therapy

    The glycoprotein CD147 has a role in tumor progression, is readily detectable in the circulation, and is abundantly expressed in hepatocellular carcinoma (HCC). Advanced HCC patients are a heterogeneous group with some individuals having dismal survival. The aim of this study was to examine circulating soluble CD147 levels as a prognostic marker in HCC patients. CD147 was measured in 277 patients (110 HCC, 115 chronic liver disease, and 52 non-liver disease). Clinical data included etiology, tumor progression, Barcelona Clinic Liver Cancer (BCLC) stage, and treatment response. Patients with HCC were stratified into two groups based upon the 75th percentile of CD147 levels (24 ng/mL). CD147 in HCC correlated inversely with poor survival (P = 0.031). Increased CD147 predicted poor survival in BCLC stages C and D (P = 0.045), and CD147 levels >24 ng/mL predicted a significantly diminished 90-day and 180-day survival time (hazard ratio [HR] = 6.1; 95% confidence interval [CI]: 2.1-63.2; P = 0.0045 and HR = 2.8; 95% CI: 1.2-12.6; P = 0.028, respectively). In BCLC stage C, CD147 predicted prognosis; levels >24 ng/mL were associated with a median survival of 1.5 months compared with 6.5 months with CD147 levels ≤24 ng/mL (P = 0.03). CD147 also identified patients with a poor prognosis independent from treatment frequency, modality, and tumor size. Circulating CD147 is an independent marker of survival in advanced HCC. CD147 requires further evaluation as a potential new prognostic measure in HCC to identify patients with advanced disease who have a poor prognosis. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Most patients with hepatocellular carcinoma present with intermediate to advanced disease, where curative therapies are no longer an option. These patients with intermediate to advanced disease represent a heterogeneous population with regard to tumor burden, liver function, and performance status. While the Barcelona Clinic Liver Cancer (BCLC) staging system offers guidelines for the management of these patients, strict adherence to these guidelines may limit treatment options for these patients. Several locoregional therapies exist for these patients, including conventional transarterial chemoembolization (cTACE), transarterial embolization (TAE), drug-eluting embolization (DEE), and radioembolization. Evidence is also emerging for the role of radiation therapy including most notably stereotactic body radiation therapy and proton therapy, although at the current time, clinical trial participation is encouraged. While cTACE is traditionally recommended for BCLC B disease, both cTACE and radioembolization are increasingly used for patients with intermediate disease, as well as in select patients with BCLC A and C disease. TAE and DEE are limited in their use currently, due to lack of clear survival benefits or clinical advantages over cTACE. While several studies have demonstrated similar OS between cTACE and radioembolization, radioembolization provides a longer time to progression and fewer toxicities compared to cTACE. This is particularly relevant in the setting of advanced BCLC B and early BCLC C disease, where patients may have limited reserve. Radioembolization also has additional roles as an alternative to ablation, inducing liver hypertrophy, treating patients with PVT, and downstaging lesions to transplant. Ongoing studies will further define the role of locoregional treatment potentially in combination with and in light of developments in systemic therapy.

    Here, we aim to investigate the molecular mechanism of regorafenib and verify the potential druggable target for the treatment of hepatocellular carcinoma (HCC). HCC cell lines (PLC5, HepG2, Hep3B, SK-Hep1, and HA59T) were used to investigate the in vitro effect of regorafenib. Phosphatase activity was analyzed in HCC cells and purified SHP-1 proteins. PLC5-bearing mice were used to test the therapeutic efficiency of 20 and 40 mg/kg/d treatment with regorafenib ([Formula: see text] mice). The clinical relevance of STAT3 signaling was investigated with 142 tumor samples from different patients with HCC. Descriptive statistical analysis was used to compare the baseline characteristics of patients and the expression of p-STAT3. Regorafenib inhibited STAT3-related signaling in a dose-dependent manner and was a more potent inhibitor of STAT3 than sorafenib. Regorafenib increased SHP-1 phosphatase activity in purified SHP-1 protein directly. N-SH2 domain deletion and D61A mutants mimicking open-form SHP-1 partially abolished regorafenib-induced STAT3 inhibition and apoptosis. Importantly, a higher level of expression of STAT3 was found in patients with advanced clinical stages (P = 0.009) and poorly differentiated tumors (P = 0.035). Regorafenib induced significant tumor inhibition by relieving the autoinhibited N-SH2 domain of SHP-1 directly and inhibiting p-STAT3 signals. STAT3 may be suitable as a prognostic marker of HCC development, and may be a druggable target for HCC-targeted therapy using regorafenib. ©2014 American Association for Cancer Research.

    Detection of thrombus is usually an incidental finding on fluorodeoxyglucose positron emission tomography/computed tomography studies. Nevertheless this is an important finding in terms of disease prognostication and in planning the treatment strategy. We herein report a case of a 50-years-old male, a diagnosed case of hepatocellular carcinoma with extensive hypermetabolic thrombus involving the entire portal venous system. (author)

    A patient with an Edmondson type I-II hepatocellular carcinoma had, at celiac angiography, a poor arterial supply but a rich portal supply as observed at percutaneous transhepatic portography, an observation not previously reported in this disease. The importance of demonstrating the vascular supply of the tumor previous to planned intravascular treatment is obvious.

    Conclusion: Cancer pain in patients with advanced hepatocellular carcinoma can be alleviated with electroacupuncture and multiple acupoint stimulation, but the onset pain relief was slow. To improve the analgesic effects of this technique, the combination of various analgesic methods should be necessary in early stage of the treatment.

    Differential diagnosis between hepatocellular carcinoma and metastatic hepatic tumor was attempted using dynamic CT scanning. Homogeneous and patchy types were peculiar to hepatocellular carcinoma, and ring-like type to metastatic hepatic tumor. However, with no enhancement, hepatocellular carcinoma could not be denied. Hepatocellular carcinoma was characterized by the enhancement shown on the early stage of dynamic CT. Ring enhancement was not visualized on dynamic CT but visualized on conventional contrast enhanced CT in hepatocellular carcinomas; it was visualized on conventional contrast enhanced CT and on dynamic CT in metastatic hepatic tumors.

    Tribbles homolog 3 (TRB3), a type of pseudokinase that contains a consensus serine/threonine kinase catalytic core structure, is upregulated in hepatocellular carcinoma. However, the effect of TRB3 expression in hepatocellular carcinoma and the molecular mechanisms underlying TRB3-mediated effects on tumorigenesis in hepatocellular carcinoma have not been fully elucidated. The present study focused on the effect of TRB3 expression in MHCC97H hepatocellular carcinoma cells and investigated the underlying molecular mechanisms in MHCC97H cells. In the present study, it was revealed that TRB3 was significantly overexpressed in the MHCC97H hepatocellular carcinoma cell compared with L-02 normal hepatic cells. Under endoplasmic reticulum (ER) stress induced by thapsigargin and tunicamycin, the levels of TRB3, CCAAT/enhancer binding protein homologous protein (CHOP), protein kinase B (AKT) and phosphorylated (p)AKT expression were upregulated. Furthermore, when the expression of TRB3 was silenced by short hairpin (sh)RNA, the survival of MHCC97H hepatocellular carcinoma cells was increased. Notably, following transduction with lentiviral containing TRB3-shRNA, cell survival also increased after treatment with chemotherapy drug cisplatin. The present study demonstrated that knockdown of CHOP by shRNA was able to reduce TRB3 expression, and the knockdown of TRB3 markedly increased the level of pAKT. TRB3 was overexpressed in MHCC97H hepatocellular carcinoma cells, particularly under endoplasmic reticulum stress. Knockdown of TRB3 was able to increase cell survival. Therefore, TRB3 expression may induce apoptosis and reverse resistance to chemotherapy in MHCC97H hepatic carcinoma cells. The present study suggests that TRB3 is a key molecule that mediates the crosstalk between ER stress and AKT signal pathways. Furthermore, the present study may provide further insight into the cancer biology of hepatocellular carcinoma and the development of anticancer drugs targeting the ER

    Although Henoch-Schönlein purpura (HSP) is known to be accompanied by malignancies, cases with hepatobiliary cancer are extremely rare. A 62-year-old man with palpable purpura rapidly extending to both lower legs was admitted to our hospital. He was undergoing follow-up for cirrhosis caused by chronic hepatitis B virus infection and hepatocellular carcinoma (HCC). He had renal dysfunction with hematuria and proteinuria and abdominal pain. Based on the clinical presentation and skin biopsy findings, he was diagnosed with HSP. The administration of steroids resulted in the rapid improvement of the patient's symptoms and he wa
