Liver cancer is one of the most frequent solid cancers. The major risk factor associated with the development of hepatocellular carcinoma (HCC) is cirrhosis caused by hepatitis B, hepatitis C virus or chronic alcohol consumption. The overall prognosis of patients with HCC is very poor and this is mainly due to the advanced stages of cancer at presentation and also because of underlying cirrhosis. When HCC is diagnosed at early stages, prognosis is better with five-year disease free survival of around 50% with resection, or local ablative treatments such as radio-frequency ablation or percutaneous ethanol injection, and 70-80% with liver transplantation. Therefore, systematic screening of all the high-risk patients is the key to an early diagnosis of small HCC and the use of an appropriate treatment modality. The currently available tools for the screening, surveillance and diagnosis of HCC in the presence of cirrhosis remain sub-optimal. The advancements made in the past 10 years, however, have made HCC a potentially curable disease in a highly selected group of patients. This review will briefly discuss the current guidelines for surveillance and diagnosis of HCC in high-risk subjects and then review the potential role of endoscopic ultrasound and fine needle aspiration for the diagnosis of small HCC. 相似文献

Background This study was carried out to clarify the carcinogenic factors associated with nonviral hepatocellular carcinoma (HCC).
Methods A total of 320 HCC patients diagnosed and treated from January 2000 to December 2006 were enrolled. The clinical characteristics
of non-B non-C HCC patients were examined to determine possible carcinogenic factors.
Results Of 320 HCC patients, 64 were classified as having non-B non-C HCC. The proportion of non-B non-C HCC increased from 17.8%
in 2000 to 28.6% in 2006. Non-B non-C HCC patients had a significantly higher rate of early stage cirrhosis (Child-Pugh classification)
than viral HCC patients. Significantly fewer non-B non-C HCC patients had periodic intensive medical assessments than viral
HCC patients. Forty-five non-B non-C HCC patients were habitual alcohol drinkers, ten had nonalcoholic fatty liver disease
(NAFLD), and seven had no apparent etiology. In habitual drinkers, the stage of underlying liver disease varied widely, while
most NAFLD patients had early stage cirrhosis. On the other hand, more than half of the patients with HCC of undetermined
etiology had noncirrhotic liver disease. Among habitual drinkers, the underlying liver disease was more progressive, and the
T stage was more advanced in those with high daily alcohol intake than in those with low daily alcohol intake. Periodic intensive
medical assessments were crucial for detecting early stage HCC.
Conclusions Alcohol consumption and NAFLD may be important etiological factors in non-B non-C HCC. Periodic medical assessments for all
patients with non-B non-C cirrhosis are crucial for early diagnosis and curative therapy. 相似文献

Image-guided thermal ablation of hepatocellular carcinoma 总被引:1,自引:0,他引:1
Hepatocellular carcinoma (HCC) is increasingly diagnosed at an early, asymptomatic stage owing to surveillance of high-risk patients. Given the complexity of the disease, multidisciplinary assessment of tumor stage, liver function, and physical status is required for proper therapeutic planning. Patients with early-stage HCC should be considered for any of the available curative therapies, including surgical resection, liver transplantation and percutaneous image-guided ablation. Resection is currently indicated among patients with solitary HCC and extremely well-preserved liver function, who have neither clinically significant portal hypertension nor abnormal bilirubin. Liver transplantation benefits patients who have decompensated cirrhosis and one tumor smaller than 5 cm or up to three nodules smaller than 3 cm, but donor shortage greatly limits its applicability. This difficulty might be overcome by living donation that, however, is still at an early stage of clinical application. Image-guided percutaneous ablation is the best therapeutic choice for nonsurgical patients with early-stage HCC. While ethanol injection has been the seminal percutaneous technique, radiofrequency ablation has emerged as the most effective method for local tumor destruction and is currently used as the primary ablative modality at most institutions. 相似文献

OBJECTIVES: To assess the feasibility and efficiency of the screening for hepatocarcinoma in a cohort of cirrhoseis mainly of alcoholic origin. PATIENTS AND METHODS: 293 patients with cirrhosis, among them 186 (63.5%) from alcoholic origin, were included in a surveillance programme for hepatocarcinoma by carrying out liver ultrasonography and alpha-foetoprotein dosage every 6 months. Results were analyzed with a mean follow-up of 60 months. Seventeen hepatocarcinoma discovered through the surveillance programme ("screened HCC") were compared with 40 hepatocarcinoma discovered outside the surveillance programme during the same period ("incidental HCC"). RESULTS: The alcoholic origin of the cirrhosis was a predictive factor of poor compliance to the surveillance programme. Among the 186 patients with alcoholic cirrhosis, 129 (69%) were lost during the surveillance programme due to lack of compliance (97 cases) or death (32 cases). By comparison, among the 65 patients with hepatitis C-related cirrhosis, 18 were lost by lack of compliance (11 cases) or death (7 cases) (P<0.001). Moreover, sustained or relapsing alcohol abuse after inclusion in the surveillance programme were also related to the quality of the compliance. Seventeen hepatocarcinoma were discovered through the surveillance giving an annual incidence of 2% for the emergence of hepatocarcinoma. The comparison between screened (n=17) and incidental (n=40) hepatocarcinoma showed that screened HCC were more often asymptomatic (P<0.01), were more often a solitary nodule less than 5 cms (P<0.001) and underwent more often curative treatment (P=0.02). However, the survival between screened and incidental hepatocarcinoma was not different. CONCLUSIONS: Screening for hepatocarcinoma in patients with alcoholic cirrhosis is a difficult task due to poor compliance and early death. According to our results, a surveillance every 6 months is sufficient to detect early lesions accessible to curative treatment by surgical resection or transcutaneous ablation. 相似文献

Chronic hepatitis B (CHB) infection is a major cause of human mortality worldwide. The majority of people with CHB are infected early in life, and 20–40% of men and 15% of women with chronic infection will develop hepatocellular carcinoma (HCC). Antiviral therapy is recommended for patients with CHB who have cirrhosis or active disease with the aims of reducing disease progression to cirrhosis, liver failure and liver cancer, thereby preventing death. Evidence that treatment with interferon or with early nucleos(t)ide analogue therapy reduces HCC has been somewhat conflicting, however evidence is emerging to support a significant role in HCC prevention of the more effective antivirals, entecavir and tenofovir. Older patients, those with cirrhosis, and those undergoing curative treatments for HCC derive the greatest medium-term benefit in terms of HCC reduction, but HCC can still occur and long-term surveillance is recommended. 相似文献

Hepatocellular carcinoma (HCC) is an aggressive tumor that often occurs in the setting of chronic liver disease. Many patients do not initially manifest any symptoms of HCC and present late when cure with surgical resection or transplantation is no longer possible. For this reason, patients at high risk for developing HCC are subjected to frequent screening processes. The surgical management of HCC is complex and requires an inter-disciplinary approach. Hepatic resection is the treatment of choice for HCC in patients without cirrhosis and is indicated in some patients with early cirrhosis (Child-Pugh A). Liver transplantation has emerged in the past decade as the standard of care for patients with cirrhosis and HCC meeting Milan criteria and in select patients with HCC beyond Milan criteria. Loco-regional therapy with transarterial chemoembolization, transarterial embolization, radiofrequency ablation and other similar local treatments can be used as neo-adjuvant therapy to downstage HCC to within Milan criteria or as a bridge to transplantation in patients on transplant wait list. 相似文献

Introduction. Imaging surveillance and multidisciplinary conference (MDC) review can potentially improve survival in patients with hepatocellular carcinoma (HCC) by increasing access to liver transplantation. Geographic disparities in donor organ availability may reduce this benefit. This study evaluated the impact of HCC surveillance on use of curative therapies and survival in a region with long transplant waiting times.Material and methods. 167 HCC patients were retrospectively studied. Subjects had an established HCC diagnosis or were diagnosed during hepatology follow-up. Collected data included patient demographics, HCC surveillance and MDC review status, portal hypertension complications, laboratory and radiologic parameters, tumor size, therapeutic interventions, tumor progression, and mortality. The primary outcome measures were use of curative treatments and survival. A Cox-regression model was constructed utilizing factors associated with survival in univariate analysis.Results. 58% of subjects underwent surveillance and MDC review of HCC. These patients were more likely to have received treatment with ablation or resection (16 vs. 3%, P = 0.006) and transplantation (23 vs. 4%, P = 0.001), and were less likely to develop tumor progression (45 vs. 68%, P = 0.005) or metastases (0 vs. 19%, P < 0.001). In multivariate analysis, surveillance and MDC review (P = 0.034, HR 0.520, 95% CI 0.284–0.952), tumor meeting Milan criteria (P < 0.001, HR 0.329, 95% CI 0.178–0.607), curative therapy application (P = 0.048, HR 0.130, 95% CI 0.017–0.979), and transplantation (P = 0.004, HR 0.236, 95% CI 0.088–0.632) were associated with survival.Conclusion. In conclusion, imaging surveillance and MDC review is associated with detection of early stage HCC, increased access to curative therapies and transplantation, and prolonged survival. 相似文献

AIM To determine the incidence of hepatocellular carcinoma(HCC) and the impact of HCC surveillance on early diagnosis and survival of cirrhotic outpatients. METHODS In this retrospective cohort study, cirrhotic outpatients undergoing HCC surveillance between March 2005 and March 2014 were analyzed. Exclusion criteria were HIV coinfection; previous organ transplantation; diagnosis of HCC at first consultation; missing data in the medical chart; and less than 1 year of follow-up. Surveillance was carried out every six months using ultrasound and serum alpha-fetoprotein determination. Ten-year cumulative incidence and survival were estimated through Kaplan-Meier analysis. RESULTS Four hundred and fifty-three patients were enrolled, of which 57.6% were male. Mean age was 55 years. Hepatitis C virus and heavy use of alcohol were the main etiologic agents of cirrhosis. HCC was diagnosed in 75 patients(16.6%), with an estimated cumulative incidence of 2.6% in the 1st year, 15.4% in the 5th year, and 28.8% in the 10 th year. Median survival was estimated at 17.6 mo in HCC patients compared to 234 mo in non-HCC patients(P 0.001). Early-stage HCC was more often detected in patients who underwent surveillance every 6 mo or less(P = 0.05). However, survival was not different between patients with early stage vs non-early stage tumors [HR = 0.54(0.15-1.89), P = 0.33].CONCLUSION HCC is a frequent complication in patients with cirrhosis and adherence to surveillance programs favors early diagnosis. 相似文献

Hepatocellular carcinoma (HCC) is one of the most common causes of cancer‐related mortality worldwide. In the last few decades, there has been a marked increase in therapeutic options for HCC and epidemiological characteristics at HCC diagnosis have also significantly changed. With these changes and advances in medical technology and surveillance program for detecting earlier stage HCC, survival in patients with HCC has significantly improved. Especially, patients with liver cirrhosis are at high risk of HCC development, and regular surveillance could enable early detection of HCC and curative therapy, with potentially improved clinical outcome. However, unfortunately, only 20% of HCC patients are amenable to curative therapy (liver transplantation, surgical resection or ablative therapies). Locoregional therapies such as radiofrequency ablation, percutaneous ethanol injection, microwave coagulation therapy and transcatheter arterial chemoembolization play a key role in the management of unresectable HCC. Currently, molecular‐targeted agents such as sorafenib have emerged as a promising therapy for advanced HCC. The choice of the treatment modality depends on the size of the tumor, tumor location, anatomical considerations, number of tumors present and liver function. Furthermore, new promising therapies such as gene therapy and immunotherapy for HCC have emerged. Approaches to the HCC diagnosis and adequate management for patients with HCC are improving survival. Herein, we review changes of epidemiological characteristics, prognosis and therapies for HCC and refer to current knowledge for this malignancy based on our experience of approximately 4000 HCC cases over the last three decades. 相似文献

High rates of excessive calorie intake diets and sedentary lifestyles have led to a global increase in nonalcoholic fatty liver disease (NAFLD). As a result, this condition has recently become one of the leading causes of hepatocellular carcinoma (HCC). Furthermore, the incidence of NAFLD-associated HCC (NAFLD-HCC) is expected to increase in the near future. Advanced liver fibrosis is the most common risk factor for NAFLD-HCC. However, up to 50% of NAFLD-HCC cases develop without underlying liver cirrhosis. Epidemiological studies have revealed many other risk factors for this condition; including diabetes, other metabolic traits, obesity, old age, male sex, Hispanic ethnicity, mild alcohol intake, and elevated liver enzymes. Specific gene variants, such as single-nucleotide polymorphisms of patatin-like phospholipase domain 3, transmembrane 6 superfamily member 2, and membrane-bound O-acyl-transferase domain-containing 7, are also associated with an increased risk of HCC in patients with NAFLD. This clinical and genetic information should be interpreted together for accurate risk prediction. Alpha-fetoprotein (AFP) is the only biomarker currently recommended for HCC screening. However, it is not sufficiently sensitive in addressing this diagnostic challenge. The GALAD score can be calculated based on sex, age, lectin-bound AFP, AFP, and des-carboxyprothrombin and is reported to show better diagnostic performance for HCC. In addition, emerging studies on genetic and epigenetic biomarkers have also yielded promising diagnostic potential. However, further research is needed to establish an effective surveillance program for the early diagnosis of NAFLD-HCC. 相似文献

Hepatocellular carcinoma in Korea: introduction and overview] 总被引:1,自引:0,他引:1
Joong-Won Park 《Taehan Sohwagi Hakhoe chi》2005,45(4):217-226
Hepatocellular carcinoma (HCC) is a highly malignant, generally fatal neoplasm arising from hepatocytes. HCC accounts for over 80% of all primary liver cancers which ranks fourth among the organ-specific causes of cancer-related deaths worldwide. HCC is particularly prevalent in Korea where the age standardized incidence rate is 46.5 per 100,000 population. Infection with hepatitis B virus (HBV) or hepatitis C virus (HCV) or presence of liver cirrhosis are important risk factors for HCC development globally. Infection with HBV is the most important risk for HCC in Asia except Japan. The high incidence rate of HCC in Korea is thought to be related to the high carrier rate (5-6%) of HBV, which is currently being fought via a nationwide vaccination program. Although progress has been made in the management of HCC including chemoembolization and local ablation therapy, there has been little overall reduction in HCC mortality during the past 20 years. Recently, five year survival rate of primary liver cancer is 9.6% in Korea. Such poor prognosis of HCC results from the late detection of cancer, an aggressive tumor biology and underlying chronic liver diseases. Only a limited proportion of patients are candidates for potentially curative forms of treatment. Therefore efforts should be directed toward an effective surveillance program. The early detection of HCC is the important approach in reducing HCC mortality in the short term. Because almost eighty percent of HCC is diagnosed in late stage, we launched a nationwide surveillance program to screen high risk groups (HBV or HCV carriers or liver cirrhosis, over 40 years old) and formulated the Korean practice guideline for the diagnosis and treatment of HCC with special emphasis on advanced stage of HCC. 相似文献

Background: The hepatitis B virus (HBV) or hepatitis C virus (HCV) markers frequently are detected in alcoholic patients with hepatocellular carcinoma (HCC). However, risk factors for the development of HCC in patients with HBs antigen (Ag)- and anti-HCV antibody (anti-HCV)-negative alcoholic cirrhosis have not been clearly documented. The present study was conducted to elucidate the occurrence rates of HCC in HBs Ag- and anti-HCV-negative male alcoholic cirrhosis and to assess the risk factors for hepatocellular carcinogenesis.
Method: We prospectively studied 91 consecutive patients with HBs Ag- and anti-HCV-negative alcoholic cirrhosis for 0.5 to 12.5 years (median 5.9 years). Potential risk factors assessed for liver carcinogenesis included the following six variables: age, total alcohol intake, association of continuing alcohol intake after diagnosis, indocyanine green retention rate at 15 min, anti-HB core antibodies (anti-HBc), and association of diabetes mellitus.
Results: Cumulative occurrence rates of HCC were 6.4%, 18.9%, and 28.7% at the end of the 5th, 7th and 10th years, respectively. When classified by anti-HBc, the occurrence rates of HCC in 31 patients with anti-HBc and 60 patients without anti-HBc were 15.6% and 2.9% at the 5th year, 28.4% and 13.5% at the 7th year, and 40.4% and 22.1% at the 10th year, respectively. The occurrence rates of HCC were also significantly related to the cumulative alcohol intake. Cox proportional hazard model identified that cumulative alcohol intake ( p = 0.0047) and positive anti-HBc antibodies ( p = 0.0598) were independently associated with the occurrence rates of HCC.
Conclusion: These epidemiologic results suggest that heavy cumulative alcohol intake and prior exposure to HBV infection are risk factors for the development of HCC in patients with HBs Ag- and anti-HCV-negative alcoholic cirrhosis. 相似文献

BACKGROUND & AIMS: HCV-related cirrhosis is a leading risk factor for hepatocellular carcinoma (HCC). Surveillance might detect HCC at a treatable stage. We estimated the clinical and economic consequences of a common HCC surveillance strategy in patients with HCV-related cirrhosis in the context of alternative HCC treatment strategies. METHODS: With a Markov model, we examined surveillance with serum alpha-fetoprotein and ultrasound every 6 months in patients with compensated HCV-related cirrhosis from age 45-70 years or death, and HCC treatment with resection, cadaveric liver transplantation (CLT), or living donor liver transplantation (LDLT). RESULTS: Compared to natural history in the base case, surveillance with resection, listing for CLT, or LDLT increased life expectancy by 0.49, 2.58, and 3.81 quality-adjusted life-years (QALYs), respectively, all at costs less than 51,000 US dollars/QALY gained. The consequences of surveillance were most sensitive to the outcomes and costs of HCC treatments but not surveillance test performance characteristics or cost. Prioritizing CLT for patients with HCC over those with decompensated cirrhosis resulted in greater overall life expectancy with minimal increase in cost. CONCLUSIONS: Surveillance for HCC in patients with compensated HCV-related cirrhosis might gain QALYs at acceptable costs. The impact of surveillance depends most on the outcomes and costs of HCC treatments, rather than surveillance test characteristics. By increasing organ availability for timely definitive treatment, LDLT might achieve the greatest gain in life expectancy at acceptable costs. Prioritizing CLT for HCC might increase the population-wide benefits of CLT. 相似文献

Background: The major cause of hepatocellular carcinoma (HCC) in the general Japanese population is an infection related to hepatotropic viruses, especially hepatitis virus C (HCV). Even in heavy drinkers, the major cause of HCC is HCV infection. However, HCC without viral infection has been reported in heavy drinkers. Alcohol has been also reported to be associated with an increased risk of cancer. In this study, we investigated aspects of HCC pathogenesis in heavy drinkers in Japan. Methods: Questionnaires were sent to 1350 hospitals authorized by the Japanese Society of Gastroenterology. The questionnaires asked about the number of inpatients with the different types of alcoholic liver diseases, admitted to each hospital between 1998 and 2001. Results: The percentage of heavy drinkers among all admitted patients with liver diseases or liver cirrhosis was approximately 15%. Of the patients with alcoholic liver cirrhosis, the cirrhosis was derived from alcohol alone in 61% and from alcohol plus a virus in 39% of patients. Furthermore, the percentage of patients with alcoholic liver cirrhosis caused by alcohol alone and who did not have HCC was 80%. However, the percentage of HCC patients who tested negative for viral hepatitis serum markers was 27% of the total number of heavy drinkers admitted for HCC. A study mainly on liver cirrhosis performed in the early 1990s demonstrated that the alcohol‐alone group accounted for 44% of admitted patients with alcoholic liver cirrhosis and 18% of heavy drinkers admitted for HCC. Conclusions: Because the consumption of alcohol is increasing in Japan, the frequency and number of cases of alcoholic liver cirrhosis are increasing. Viral hepatitis infection, however, still plays an important role in hepatocarcinogenesis in heavy drinkers. Radiographical examination is recommended even in patients with alcoholic liver cirrhosis who test negative for serum markers of viral hepatitis. 相似文献

Surveillance for hepatocellular carcinoma: compliance and results according to the aetiology of cirrhosis in a cohort of 141 patients 总被引:5,自引:0,他引:5

Surveillance for early detection of hepatocarcinoma (HCC) in patients with cirrhosis is widely accepted. In a cohort of 141 patients with cirrhosis collected during the year 1995, we conducted a surveillance program by performing liver ultrasonography and blood alpha-foetoprotein measurement every 6 months. The median follow-up was 34 months. This study addressed to two questions: the compliance to the surveillance schedule according to the aetiology of cirrhosis and the results in terms of emergence of HCC and outcome. Aetiology of cirrhosis was alcohol-induced in 86 (61%), HCV-related in 30 (21%) and from other origins in 25 (18%). Compliance to the program schedule was good in patients with HCV-related cirrhosis (29/30--97%) and patients with cirrhosis of "other origins" (20/25--80%) but was poor in patients with alcoholic cirrhosis (45/86--52%). The lack of compliance was significantly linked to the failure to achieve alcohol abstinence. During follow-up, 6 HCC lesions were observed in 6 male patients with median age of 68 years. All 6 HCC were single nodule, less than 4 cm and accessible to percutaneous acetic acid injection. Nevertheless, the outcome was disappointing, four patients dying 3-15 months later (median: 8 months), two of them with extensive HCC. One of the two patients still alive developed extensive HCC, 36 months after percutaneous acetic acid injection. 相似文献

Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world, and is the third highest cause of cancer-related mortality. HCC usually develops in patients with chronic liver disease, particularly in those who also have cirrhosis. The possibility of curative treatment depends on both the stage of tumor and liver function. Effective treatments for HCC include percutaneous ablation, surgical resection, and liver transplantation. Both percutaneous ablation and surgical resection provide a high rate of complete responses and are assumed to improve survival that should exceed 50% at 5 years. Liver transplantation results in a better survival rate, and is not contraindicated by advanced liver dysfunction. However, its application is limited by the scarcity of donor organs. Treatments for advanced HCC include transarterial chemoembolization and chemotherapy. Although short-term prognosis of HCC patients has improved recently due to advances in early diagnosis and treatment, long-term prognosis is as yet far from satisfactory due to frequent recurrence. Prevention of recurrence of HCC remains one of the most challenging tasks in current hepatology. 相似文献

Opinion statement Hepatocellular carcinoma (HCC) most commonly affects patients with underlying cirrhosis. Screening of cirrhotic patients can
result in early detection of HCC. If the tumor is localized to the liver, the patient can be offered therapy. It is our belief
that those patients with good liver function (Child-Pugh A/B or better) should be considered for surgical resection of one
or two surgical segments of the liver. Otherwise, ablative measures, including radiofrequency ablation (RFA), cryotherapy,
or angiographic embolization should be offered to the patient. Alternatively, direct injection of alcohol or acetic acid can
result in effective ablation of the lesion, with unclear effects on long-term outcome. Chemotherapy does not appear to impact
survival, but it is our belief that combined protocols may offer superior outcomes to single therapeutic interventions. Orthotopic
liver transplantation (OLT) can have excellent efficacy in a very select group of patients. 相似文献

Management of hepatocellular carcinoma (HCC) has been continuously evolving during recent years. HCC is a worldwide clinical and social issue and typically a complicates cirrhosis. The incidence of HCC is increasing, not only in the general population of patients with cirrhosis, but particularly in some subgroups of patients, like those with human immunodeficiency virus infection or thalassemia. Since a 3% annual HCC incidence has been estimated in cirrhosis, a bi-annual screening is generally suggested. The diagnostic criteria of HCC has recently had a dramatic evolution during recent years. HCC diagnosis is now made only on radiological criteria in the majority of the cases. In the context of cirrhosis, the universally accepted criteria for HCC diagnosis is contrast enhancement in arterial phase and washout in venous/late phase at imaging, the so called “typical pattern”. However, recently updated guidelines slightly differ in diagnostic criteria. Apart from liver transplantation, the only cure of both HCC and underlying liver cirrhosis, all the other treatments have to match with higher rate of HCC recurrence. The latter can be classified into curative (resection and percutaneous ablation) and palliative treatments. The aim of this paper was to review the current knowledge on management of HCC and to enlighten the areas of uncertainty. 相似文献
