RESUMO

BACKGROUND & AIMS: More than 90% of cases of hepatocellular carcinoma (HCC) occur in patients with cirrhosis, of which alcohol is a major cause. The CIRRAL cohort aimed to assess the burden of complications in patients with alcoholic cirrhosis, particularly the occurrence of HCC. METHODS: Patients with biopsy-proven compensated alcoholic cirrhosis were included then prospectively followed. The main endpoint was the incidence of HCC. Secondary outcomes were incidence of hepatic focal lesions, overall survival (OS), liver-related mortality and event-free survival (EFS). RESULTS: From October 2010 to April 2016, 652 patients were included in 22 French and Belgian centers. During follow-up (median 29 months), HCC was diagnosed in 43 patients. With the limitation derived from the uncertainty of consecutive patients' inclusion and from a sizable proportion of dropouts (153/652), the incidence of HCC was 2.9 per 100 patient-years, and one- and two-year cumulative incidences of 1.8% and 5.2%, respectively. Although HCC fulfilled the Milan criteria in 33 cases (77%), only 24 patients (56%) underwent curative treatment. An explorative prognostic analysis showed that age, male gender, baseline alpha-fetoprotein, bilirubin and prothrombin were significantly associated with the risk of HCC occurrence. Among 73 deaths, 61 had a recorded cause and 27 were directly attributable to liver disease. At two years, OS, EFS and cumulative incidences of liver-related deaths were 93% (95% CI 90.5-95.4), 80.3% (95% CI 76.9-83.9), and 3.2% (95% CI 1.6-4.8) respectively. CONCLUSION: This large prospective cohort incompletely representative of the whole population with alcoholic cirrhosis showed: a) an annual incidence of HCC of up to 2.9 per 100 patient-years, suggesting that surveillance might be cost effective in these patients; b) a high proportion of HCC detected within the Milan criteria, but only one-half of detected HCC cases were referred for curative treatments; c) a two-year mortality rate of up to 7%. LAY SUMMARY: Cirrhosis is a risk factor for primary liver cancer, leading to recommendations for periodic screening. However, for alcohol-related liver disease the rational of periodic screening for hepatocellular carcinoma (HCC) is controversial, as registry and databased studies have suggested a low incidence of HCC in these patients and highly competitive mortality rates. In this study, a large cohort of patients with biopsy-proven alcoholic cirrhosis prospectively screened for HCC demonstrated a high annual incidence of HCC (2.9%) and a high percentage of small cancers theoretically eligible for curative treatment. This suggests that patients with liver disease related to alcohol should not be ruled out of screening.

RESUMO

BACKGROUND: Type 2 diabetes is a risk factor for steatohepatitis and fibrosis. Non-invasive liver stiffness (LS) and controlled attenuation parameter (CAP) measurements by Fibroscan allow assessing liver fat and fibrosis. AIM: To determine the prevalence of steatosis and significant fibrosis in a community-based diabetic population. METHODS: LS and CAP were measured in 705 patients using the standard "M probe." A second "XL probe" was used, without CAP measurement, in case of failure with the "M probe." RESULTS: LS and CAP measurements were obtained in 437 patients (the M group), LS measurements (LSM) with the XL probe being available in additional 232 patients. After the combined use of both probes, LSM failure and unreliable result were 1.6% and 5.6% respectively. Overall, 12.7% (n=85), 7.3% and 2.1% exhibited significant or advanced fibrosis or cirrhosis (LSM≥8 kPa, ≥9.6 kPa, ≥13 kPa respectively), half of the patients with LSM≥8 kPa displayed normal liver tests. Significant and severe steatosis were measured in 75% and 24% of the M group patients. By multivariate analysis, factors associated with severe fibrosis were age, overweight, high GGT. Forty-seven patients with LSM≥8 kPa underwent liver biopsy; 93% had steatosis and 51% severe fibrosis. A significant correlation was found between LSM values and fibrosis score with an accuracy rate of 83%, 68% and 83% for LSM≥8 kPa, ≥9.6 kPa and ≥13 kPa respectively. CONCLUSIONS: The prevalence of significant steatosis is very high and significant fibrosis affect 12.7% of the patients. Fibroscan is an effective procedure to screen for fibrosis and steatosis in diabetic patients.

RESUMO

BACKGROUND & AIMS: The prevalence of fatty liver underscores the need for non-invasive characterization of steatosis, such as the ultrasound based controlled attenuation parameter (CAP). Despite good diagnostic accuracy, clinical use of CAP is limited due to uncertainty regarding optimal cut-offs and the influence of covariates. We therefore conducted an individual patient data meta-analysis. METHODS: A review of the literature identified studies containing histology verified CAP data (M probe, vibration controlled transient elastography with FibroScan®) for grading of steatosis (S0-S3). Receiver operating characteristic analysis after correcting for center effects was used as well as mixed models to test the impact of covariates on CAP. The primary outcome was establishing CAP cut-offs for distinguishing steatosis grades. RESULTS: Data from 19/21 eligible papers were provided, comprising 3830/3968 (97%) of patients. Considering data overlap and exclusion criteria, 2735 patients were included in the final analysis (37% hepatitis B, 36% hepatitis C, 20% NAFLD/NASH, 7% other). Steatosis distribution was 51%/27%/16%/6% for S0/S1/S2/S3. CAP values in dB/m (95% CI) were influenced by several covariates with an estimated shift of 10 (4.5-17) for NAFLD/NASH patients, 10 (3.5-16) for diabetics and 4.4 (3.8-5.0) per BMI unit. Areas under the curves were 0.823 (0.809-0.837) and 0.865 (0.850-0.880) respectively. Optimal cut-offs were 248 (237-261) and 268 (257-284) for those above S0 and S1 respectively. CONCLUSIONS: CAP provides a standardized non-invasive measure of hepatic steatosis. Prevalence, etiology, diabetes, and BMI deserve consideration when interpreting CAP. Longitudinal data are needed to demonstrate how CAP relates to clinical outcomes. LAY SUMMARY: There is an increase in fatty liver for patients with chronic liver disease, linked to the epidemic of the obesity. Invasive liver biopsies are considered the best means of diagnosing fatty liver. The ultrasound based controlled attenuation parameter (CAP) can be used instead, but factors such as the underlying disease, BMI and diabetes must be taken into account.

RESUMO

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 < .003). Three major complications occurred (2.7%): hemothorax in one patient and liver failure in two, with major portal-systemic shunts. One patient (0.9%) died, and one underwent transplantation. Conclusion No-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.

RESUMO

BACKGROUND: Nodular regenerative hyperplasia (NRH) is a rare histological disorder associated with a wide variety of systemic diseases. AIMS: We aimed (i) to report the prevalence of NRH in a database of liver biopsies (LBs) and the frequency of portal hypertension (PHT) at diagnosis, and (ii) to investigate whether associated diseases and/or specific histological lesions, including abnormalities of the microvasculature, were related to PHT. METHODS: Patients with a histological diagnosis of NRH, referred by seven clinical departments, were retrospectively selected. Clinical, biological, radiological, haemodynamic and endoscopic data at diagnosis were recorded. LBs were reassessed for microvascular abnormalities. RESULTS: NRH was diagnosed in 4.4% of LBs (n = 159, male: 52%, mean age: 54). Among patients referred for unexplained liver enzyme abnormalities, 15% had NRH. PHT was present at diagnosis in 45 patients (38%), including 13 with portal thrombosis; 65% of patients had an associated disorder. Obliteration of portal vein branches, observed in the LBs of 17 patients (11%), was significantly associated with PHT (P = 0.02). Periportal angiomatosis, observed in 101 patients (63%), was associated with the absence of PHT (P < 10(-4) ). CONCLUSION: We suggest that NRH is a frequent histological lesion in the setting of unexplained liver enzyme abnormalities. PHT is present at the time of diagnosis in 1/3 of patients regardless of the presence of associated disease. The frequency of periportal angiomatosis in NRH without obliteration of portal vein branches, and its association with the absence of PHT suggest that obstructive portal venopathy would not represent the most frequent mechanism involved in NRH.

RESUMO

BACKGROUND & AIMS: A novel controlled attenuation parameter (CAP) using the signals acquired by the FibroScan® has been developed as a method for evaluating steatosis. The aim of this study is to assess the performance of the CAP for the detection and quantification of steatosis in patients with chronic hepatitis B (CHB). MATERIAL AND METHODS: 136 subjects with CHB underwent liver biopsy and FibroScan® within 60 days. CAP was evaluated retrospectively using raw FibroScan® data. Steatosis was graded as follows: S0 (steatosis < 10% of hepatocytes), S1 (10 to < 30%), S2 (30 to < 60%) or S3 (≥ 60%). Performance was evaluated by area under the receiver operating characteristic (AUROC) curve. RESULTS: Proportions of each steatosis grade (S0-S3) were 78, 10, 9 and 3%, respectively. Using univariate analysis, liver stiffness measurement (LMS) significantly correlated with fibrosis (τ = 0.43; P < 10-10), sex, necro-inflammatory activity, steatosis, age, NASH, and perisinusoidal fibrosis, and with liver fibrosis (P < 10-8) and perisinusoidal fibrosis (P = 0.008) using multivariate analysis. CAP correlated with steatosis (τ = 0.38, P < 10-7), body mass index, NASH, fibrosis and perisinusoidal fibrosis using univariate analysis, but only steatosis (P < 10-10) and perisinusoidal fibrosis (P = 0.002) using multivariate analysis. AUROCs for LSM were: 0.77 (0.69-0.85), 0.87 (0.80-0.95), and 0.93 (0.83-1.00), respectively, for fibrosis stages F ≥ 2, F ≥ 3 and F = 4. AUROCs for CAP were: 0.82 (0.73-0.92), 0.82 (0.69-0.95), and 0.97 (0.84-1.00) for ≥ S1, ≥ S2 and S3 steatosis, respectively. CONCLUSIONS: In conclusión CAP is a novel, accurate non-invasive tool and may be suitable for detecting and quantifying steatosis in CHB patients.

RESUMO

BACKGROUND & AIMS: It is well known that inflammation increases liver stiffness (LS) in patients with chronic hepatitis C (HCV) and alcoholic liver disease (ALD) independent of fibrosis stage, but no inflammation-adapted cut-off values have been settled so far. An early identification of rapid fibrosers, however, is essential to decide whom to treat first with the novel but expensive antiviral drugs. METHODS: Liver stiffness, biopsy-proven fibrosis stages F0-F4 (METAVIR or Kleiner score) and routine laboratory parameters were studied in 2068 patients with HCV (n = 1391) and ALD (n = 677). RESULTS: Among the routine parameters for liver damage, AST correlated best with LS (HCV: r = 0.54, P < 0.0001 and ALD: r = 0.34, P < 0.0001). In the absence of elevated transaminases, cut-off values were almost identical between HCV and ALD for F1-2, F3 and F4 (HCV: 5.1, 9.0 and 11.9 kPa vs ALD: 4.9, 8.1 and 10.5 kPa). These cut-off values increased exponentially as a function of median AST level. The impact of AST on LS was higher in lobular-pronounced ALD as compared to portal tract-localized HCV. Most notably, Cohen's weighted Kappa displayed an improved agreement of the novel AST-dependent cut-off values with histological fibrosis stage both for HCV (0.68 vs 0.65) and ALD (0.80 vs 0.76). CONCLUSIONS: The novel AST-adapted cut-off values improve non-invasive fibrosis staging in HCV and ALD and may be also applied to other liver diseases. Especially in HCV, they could help to decide whom to treat first with the novel but expensive antiviral drugs.

RESUMO

BACKGROUND & AIMS: Genetic polymorphisms modulate the expression of proinflammatory cytokines. We prospectively assessed the influence of 6 single nucleotide polymorphisms (SNPs) in TNFα, IL6, and IL1ß genes on the risk of hepatocellular carcinoma (HCC) in patients with cirrhosis. METHODS: TNFα (G-238A, C-863A, G-308A), IL6 (C-174G), and IL1ß (C-31T, C-511T) SNPs were assessed in 232 alcoholics and 253 HCV-infected patients with biopsy-proven cirrhosis, prospectively followed-up and screened for HCC. Their influence on HCC development was assessed using the Kaplan-Meier method. RESULTS: These variants did not influence the risk of HCC in alcoholic patients. Conversely, two variants influenced the risk of HCC occurrence in patients with HCV-related cirrhosis, namely the TNFα-308 (A) allele (HR = 2.4 [1.6-3.7], Log-rank <0.0001) and the IL1ß-31 (T) allele (HR = 1.5 [1.1-2.1], Log-rank = 0.004). When stratifying HCV-infected patients into four genotypic associations expected to progressively increase TNFα and IL1ß production, we observed increasing risk of HCC occurrence (Log-rank <0.0001) from group 1 to 4. The TNFα-308 (A) allele was the only genetic trait independently associated with risk of HCC in these patients, along with older age, male gender, BMI, and platelet count. These variables led to construction of a predictive score able to separate patients with HCV-related cirrhosis into three subgroups with progressively increasing 5-year cumulative incidences of 4.7%, 14.1%, and 36.3%, respectively (Log-rank <0.0001). CONCLUSIONS: Genetic heterogeneity in the TNFα and IL1ß gene promoters influences the risk of HCC in patients with HCV-induced cirrhosis. These genetic data, when incorporated into clinical scores, are able to refine selection of risk classes of HCC.

RESUMO

CONTEXT: Paucisymptomatic forms of Turner's syndrome (TS), in which short stature is the predominant clinical abnormality, remain underdiagnosed. Abnormal liver tests are extremely frequent in adult TS patients reflecting various types of hepatic lesions. OBJECTIVE: The objective of the study was to investigate whether unexplained elevated liver enzymes in women with short stature could reveal X chromosome abnormalities of undiagnosed TS. DESIGN AND PARTICIPANTS: Thirty-one consecutive short stature women displaying elevated liver enzymes and no previous diagnosis of TS were compared with 31 age-matched controls in a prospective study. Liver biopsy was performed in 26 patients. MAIN OUTCOME MEASURES: Systematic karyotype analysis and fluorescence in situ hybridization. RESULTS: X chromosome abnormalities were found in 27 patients and one control (87.0% vs 3.2%, P < .0001), including a 45,X/46,XX mosaicism in 24 patients and isochromosome of the long arm in three. Liver histological analysis showed architectural changes in 17 patients with nodular regenerative hyperplasia in 12. Biliary lesions were present in 13 patients and liver steatosis in 20. CONCLUSIONS: X chromosome abnormalities indicative of cryptic TS are extremely frequent in short-stature women with unexplained elevated liver enzymes. In short-stature women, abnormal liver tests should lead to systematic karyotype analysis.

RESUMO

PURPOSE: To compare histopathologically the completeness of radiofrequency (RF) ablation to treat hepatocellular carcinoma (HCC) with monopolar or multipolar technique. MATERIALS AND METHODS: Thirty-five consecutive patients (mean age, 59 y) with cirrhosis and HCC (n = 59) within Milan criteria received RF ablation and subsequently underwent liver transplantation (LT) for tumor progression or liver failure. Data were extracted retrospectively from a prospective database. Thirty nodules were treated with a monopolar device with internally cooled (n = 17) or perfused (n = 13) electrodes, and 29 were treated with a multipolar technique with internally cooled electrodes based on the "no-touch" concept. This consisted of inserting two or three straight electrodes around the nodule to avoid intratumor puncture to the greatest extent possible. Effectiveness of the three devices was compared by histopathologic examination of explants. Fisher exact and χ(2) tests and multivariate logistic regression analysis were performed. RESULTS: Mean sizes of nodules ablated (25, 22, and 21.6 mm) and median times from ablation to LT (11, 7.5, and 8.4 months) for patients treated with the monopolar internally cooled electrode device (MoICD), monopolar perfused electrode device (MoPED), and multipolar internally cooled electrode device (MuICD), respectively, were similar (P = .8 and P = .9, respectively). Pathologic examination showed complete necrosis for eight of 17 and six of 13 nodules treated with the MoICD and MoPED, respectively, versus 26 of 29 treated with the MuICD (P = .0019). In multivariate analysis, RF technique remained the predictive factor for complete necrosis (P = .005). CONCLUSIONS: Ablation of small HCCs with multipolar RF ablation based on the no-touch concept improves the rate of complete necrosis during pathologic examination compared with monopolar techniques.

RESUMO

Within 5 years after percutaneous ablation of hepatocellular carcinoma, roughly 70% of patients experience tumor recurrence. Relapses beyond curative options affected patients' survival. Ablation shares with resection common predictive factors of recurrence as size of the tumor, multinodularity and presence of vascular invasion. High serum α-fetoprotein level and markers of severity of underlying liver disease have also been found to be associated with recurrence and even survival. However, predictive values for recurrence of technical factors, histopathological and molecular tumors' features have been rarely studied. Few comparative studies have shown that ablation techniques impact recurrence rates. Moreover, although ablation does not allow analysis of the whole tumor, some reports suggest that biopsies allow histopathological and even molecular testing of the risk of recurrence.

RESUMO

BACKGROUND & AIMS: The prognosis of hepatocellular carcinoma (HCC) treated by radiofrequency ablation (RFA) is mainly linked to tumor recurrence. So far, no tissue biomarker of recurrence has been validated in biopsy samples. We aimed at investigating the prognostic value of tissue biomarkers in HCC biopsy samples of patients treated with RFA. METHODS: All consecutive naive patients from 3 university hospitals, with compensated cirrhosis, early-stage (BCLC 0/A) uninodular HCC treated with RFA, and available tumor biopsy, were included. Edmondson's grade, and the expression of cytokeratin 19, glutamine synthase, beta-catenin, epithelial cell adhesion molecule (EpCAM), and endothelial cell-specific molecule 1 (ESM-1) were assessed. Main clinical end points were overall and early recurrence. Statistical analyses were performed using Kaplan Meier, Log-rank test, and Cox models. RESULTS: 150 patients were included. Recurrence, death or liver transplantation occurred in 85, 51, and 12 patients, respectively. Median follow-up was 27months. ESM-1 expression by HCC stromal endothelial cells was observed in 58 patients (40%) and was associated with higher serum AFP levels, larger tumor, and more frequent expression of EpCAM and surrogate markers of activation of the Wnt-ß-catenin pathway. The 2 independent predictive factors of overall recurrence were serum AFP (HR 1.11 [1.002; 1.22], p=0.045) and ESM-1 expression (HR 1.56 [1.004; 2.43], p=0.048). ESM-1 expression was also an independent predictive factor of early recurrence (HR 1.81 [1.02; 3.21], p=0.042). CONCLUSIONS: ESM-1 expression by stromal endothelial cells, in tumor biopsy samples, has an independent predictive value of early recurrence after RFA.

RESUMO

BACKGROUND: Proteoglycans are involved in neoangiogenesis and transduction of oncogenic signals, two hallmarks of carcinogenesis. METHODS: This study sought to assess the prognostic value of serum levels of three proteoglycans (endocan, syndecan-1, and glypican-3) and VEGF in 295 patients with alcoholic cirrhosis: 170 without hepatocellular carcinoma, 58 with early hepatocellular carcinoma, and 67 with advanced hepatocellular carcinoma at inclusion. We analyzed the association between proteoglycan levels and prognosis using Kaplan-Meier and Cox methods. RESULTS: Serum levels of the three proteoglycans and VEGF were increased in patients with advanced hepatocellular carcinoma compared with those without hepatocellular carcinoma or with early hepatocellular carcinoma. In multivariate analysis, high levels of serum endocan (>5 ng/mL) were independently associated with death [HR, 2.84; 95% confidence interval (CI,) 1.18-6.84; P = 0.02], but not with hepatocellular carcinoma occurrence, in patients without hepatocellular carcinoma at baseline. High serum endocan (>5 ng/mL) and syndecan-1 (>50 ng/mL) levels were significantly associated with greater risk of tumor recurrence (P = 0.025) in patients with early hepatocellular carcinoma treated by radiofrequency ablation. In patients with advanced hepatocellular carcinoma, high serum levels of endocan (P = 0.004) and syndecan-1 (P = 0.006) were significantly associated with less favorable overall survival. However, only a high level of serum syndecan-1 (>50 ng/mL) was independently associated with greater risk of death (HR, 6.21 95% CI, 1.90-20.30; P = 0.0025). CONCLUSION: Serum endocan and syndecan-1 are easily assessable prognostic serum biomarkers of overall survival in alcoholic cirrhosis with and without hepatocellular carcinoma. IMPACT: These new biomarkers will be useful to manage patients with hepatocellular carcinoma developed on alcoholic cirrhosis.

RESUMO

BACKGROUND: As liver cancer incidence and mortality remain high in many parts of Europe, a more comprehensive response is required to reduce the burden. Expert stakeholders should be involved in the design of responses because they have important insights about potentially effective responses and will be affected by policy changes. We aimed to prioritize liver cancer control strategies based on European liver cancer stakeholders' views of which strategies would have the greatest impact in a comprehensive liver cancer control plan. METHODS: One hundred liver cancer clinical, policy and advocacy stakeholders from France, Germany, Italy, Spain and Turkey were surveyed. Respondents completed 12 conjoint choice tasks in which they chose which of two subsets of 11 strategies would have the greatest impact in their country. RESULTS: All strategies were considered likely to have a positive impact (P < 0.01). The highest priority strategy was monitoring of at-risk populations, followed by centres of excellence, clinical education, multidisciplinary management, national guidelines, measuring social burden, public awareness, risk assessment and referral, research infrastructure and access to treatments. CONCLUSIONS: Canvassing stakeholder views through a conjoint analysis survey provided a robust quantitative prioritization that can complement traditional qualitative consultation processes. The prioritized strategies provide a logical starting point for decision makers considering developing national plans or collaborative efforts to achieve comprehensive liver cancer control in Europe.

RESUMO

Cyproterone acetate (CPA) is an oral anti-androgen commonly used to treat advanced prostate cancer. A variety of hepatotoxic reactions has been reported with CPA. Here we describe a case of a male patient who developed severe drug-induced hepatotoxicity during the treatment with CPA. The case, presenting sub-acute hepatitis, was characterized by a rapid evolution of cirrhosis and a protracted activity during the period of a few months despite the treatment withdrawal and an apparent benefits of corticosteroids, suggesting their indication in life threatening cases.

RESUMO

BACKGROUND & AIMS: Several studies have reported an association between the genetic variant rs738409 (G) in the PNPLA3 gene and the risk of cirrhosis in various liver diseases. Our purpose was to assess the influence of this polymorphism on the risk of hepatocellular carcinoma (HCC) occurrence in two distinct longitudinal cohorts of patients with cirrhosis as well as its possible usefulness in HCC-risk model prediction. METHODS: PNPLA3 rs738409 genotypes were assessed in 279 patients with alcoholic- and 253 patients with HCV-related cirrhosis. These patients were followed-up and screened for the risk of HCC, and the influence of rs738409 on the occurrence of liver cancer was assessed using the Kaplan-Meier method, then according to the multivariate Cox model. RESULTS: In patients with HCV-related cirrhosis, rs738409 genotypes did not influence the risk of HCC development (log-rank = 0.7) or death (log-rank = 0.2). Conversely, in patients with alcoholic cirrhosis, the rs738409 (GG) genotype was an independent risk factor for HCC occurrence (HR = 1.72 [1.21-2.45], log-rank = 0.002) as well as older age, male gender, and higher BMI. Combining these features enabled HCC-risk stratification of this population into three groups with the 6-year cumulative incidence ranging from 3.4% (low risk, n = 58), 12.2% (intermediate risk, n = 163), and 51.7% (high risk, n = 58), respectively (HR = 4.3 [2.7-6.4]; log-rank <0.0001). CONCLUSIONS: This study provides key data that affirm the influence of the rs738409 (GG) genotype on the occurrence of HCC in patients with alcoholic cirrhosis. Its combination with clinical features refines the selection of patients at higher risk of liver cancer development.

RESUMO

BACKGROUND/AIM: Peripheral intrahepatic cholangiocarcinoma (ICC) occurring mainly in the absence of cirrhosis represents an increasing subgroup of primary liver tumors in Western countries. Histopathologic changes in the non-neoplastic liver in this context are not well characterized. PATIENTS AND METHODS: We assessed the clinical characteristics and histopathologic changes in the distant nontumoral liver of 57 consecutive White patients (34 men, mean age 59 years) referred to one medical and one surgical liver institution over a 16-year period who developed a peripheral ICC in the absence of cirrhosis or bile duct disease. RESULTS: High alcohol consumption was observed in 11 patients (20%), 38 patients (66%) had a BMI of 25 kg/m or more, 22 patients (40%) had diabetes, two patients had hepatitis B virus infection, two others had hepatitis C virus infection, three patients had genetic hemochromatosis, and two patients had cutaneous porphyria tarda. The distant nontumoral liver was normal in 10 patients (18%). The two main histopathologic changes observed were macrovesicular steatosis (>10% of hepatocytes) in 38 patients (66%), including 11 patients (19%) with steatohepatitis, and moderate or intense hepatocyte iron overload in 22 patients (38%). CONCLUSION: This study shows a high prevalence of macrovesicular steatosis associated or not with steatohepatitis and iron overload in patients who develop peripheral ICC in the absence of cirrhosis or bile duct disease.

RESUMO

We report a case of complete hemidiaphragmatic necrosis with liver abscess complicating radiofrequency ablation of a large subdiaphragmatic hepatocellular carcinoma in a patient with unrecognized history of endoscopic oddi sphincterotomy. At 2-year follow-up after surgical repair using a pedicled latissimus dorsi flap, clinical examination and imaging did not show complication or cancer recurrence. The risk of complete hemidiaphragmatic necrosis resulting from both thermal and septic injuries should be considered when radiofrequency ablation is performed for liver dome tumors, particularly in patients with impaired oddi sphincter. In this septic situation, a latissimus dorsi flap appears as the unique opportunity to repair the injured hemidiaphragm.

RESUMO

Hepatocellular carcinoma is responsible for around 6 000 deaths each year in France. About 90% of patients have underlying liver cirrhosis. The annual incidence rate in such patients is estimated at between 2% and 4%, but it is largely dependent on the cause and severity of the underlying liver disease, as well as on epidemiological factors such as age, sex, and the body mass index. Multiple genetic polymorphisms are also involved. Screening for hepatocellular carcinoma is indicated for patients with cirrhosis, based on ultrasonographic examination every six months. It allows early diagnosis and curative treatment in most cases but is still under-used.
