The expression of manganese superoxide dismutase (Mn−SOD) was studied immunohistochemically, using a specific monoclonal antibody, in surgically resected hepatocellular carcinoma (HCC) and noncancerous tissues from 47 patients (2 with well-differentiated HCC, 36 with moderately differentiated HCC, 8 with poorly differentiated HCC, and 1 with undifferentiated carcinoma). Cancer cells in 44 patients (93.6%) were positive for Mn−SOD. The staining pattern of cancer cells was mostly homogeneous in well-differentiated HCC, whereas it was heterogeneous in poorly differentiated HCC. Moreover, strongly positive immunoreactivity was observed in noncancerous liver tissues in all patients, especially in normal hepatocytes surrounding HCC, regenerative small hepatocytes in the tumor boundary, and mononuclear inflammatory cells in the necroinflammatory lesions. The positive immunoreactivity for Mn−SOD in patients with HCC appears to reflect increased production of the enzyme protein.  相似文献

A case of juvenile hepatocellular carcinoma (HCC) with congestive liver cirrhosis is reported. The patient was a 21-year-old woman. She had been diagnosed as having transposition of the great arteries, type 2, in 1978. She underwent the Mustard operation, but suffered from chronic heart failure. In 1995, she experienced abdominal pain and underwent examination. The laboratory data were normal, except for elevated total bilirubin (5.2mg/dl). Blood examinations were performed at frequent intervals, and the total bilirubin level fluctuated between 0.9 and 8.1mg/dl over the next 4 years, but the transaminase level remained normal. In 1999, she experienced abdominal pain again and was admitted to our hospital. Computed tomography showed four space-occupying lesions in the liver; 45mm, 20mm, 12mm, and 10mm in size. She was diagnosed as having HCC, and transcatheter arterial chemoembolization and percutaneous ethanol injection therapy were performed. Histology of the cancerous and the noncancerous liver tissue revealed HCC, moderately differentiated type, in cirrhotic liver with congestion. This patient had no background factors of liver disease, except for liver congestion, associated with the chronic heart failure. Because most patients with cardiac cirrhosis die of cardiac disease, only a small number of these patients develop liver failure. However, the incidence of HCC in patients with congestive liver disease is likely to increase in the future, as survival time is prolonged with the advances in treatment for chronic heart failure. Therefore, patients with congestive liver disease should be followed, taking into account the possibility of HCC.  相似文献

Background: Tacrolimus and cyclosporin inhibits the activity of calcineurin, a serine/threonine phosphatase that is involved in many physiological and pathological pathways. However, the baseline calcineurin phosphatase activity (CPA) measured before the transplant is unknown. In this study, we determine baseline CPA in liver transplant (LT) candidates and explore some factors that might modify it. Patients and methods: Thirty‐two consecutive LT candidates (25 men, seven women, average age 53.4 years) were included. Seven millilitres of whole blood was collected from each patient. CPA was determined in lymphocytes quantifying a dephosphorylated peptide phosphorylated previously (D‐L‐D‐V‐P‐I‐P‐G‐R‐F‐D‐R‐R‐V‐S‐V‐A‐A‐E) by high‐performance liquid chromatography. The relationship between CPA and the quantitative variables was tested according to Pearson's correlation. A two‐way analysis of variance was performed to test the independent role of categorical parameters in CPA. Results: The median CPA was significantly lower in LT candidates than in healthy volunteers [179.2 (146.9–226.3) vs 247.8 (220.9–292.5) pmol/min/106 peripheral blood mononuclear cell (PBMC), respectively, P=0.0002]. CPA was also significantly lower in alcoholic cirrhosis (152.2 vs 211.1 pmol/min/106 PBMC, P=0.04) and in the presence of hepatocellular carcinoma (HCC) (152.0 vs 213.5 pmol/min/106 PBMC, P=0.0074) compared with other liver diseases. A two‐way analysis of variance showed that these parameters were independently associated with lower CPA (P=0.05 for alcohol and P=0.0056 for HCC respectively). Conclusion: This pilot study showed a lower CPA in patients with AC and HCC. This phenomenon may contribute towards lowering the risk of acute rejection in these patients after LT and, on the other hand, may increase the risk of de novo cancers.  相似文献

Laparoscopic prediction of hepatocellular carcinoma in cirrhosis patients   总被引:1,自引:0,他引:1  
Previously, laparoscopic studies have not been successful in predicting the occurrence of small hepatocellular carcinoma because cirrhotic patients had not been separated into groups of those who developed small hepatocellular carcinoma under 3 cm in diameter, and those who did not. Retrospective examination with better separation of the two groups gave improved results. Of the 26 laparoscopic findings, only the presence of large complex regenerative nodules was closely associated with the occurrence of subclinical small hepatocellular carcinoma. The study of other cirrhotic patients with and without large complex regenerative nodules gave a cumulative hepatocellular carcinoma occurrence rate of 73% for patients who had these nodules by the third year after laparoscopy. In contrast, the rate for patients without such nodules was 6%, showing a significant difference (P < 0.05) between the two groups. We concluded that the laparoscopic finding of large complex regenerative nodules of liver cirrhosis can be used to predict the occurrence, or a complication, of subclinical small hepatocellular carcinoma.  相似文献

BACKGROUND: The usefulness of C-reactive protein (CRP) as a tumour marker in patients with hepatocellular carcinoma (HCC) is controversial. The purpose of this study was to determine whether CRP estimation could be used to identify patients with HCC among those with cirrhosis. METHODS: Serum levels of CRP and alpha-fetoprotein (AFP) were investigated in 122 previously untreated patients with cirrhosis and HCC. Another 76 patients with cirrhosis alone were also investigated as controls. RESULTS: Of the subjects tested, 47.5% of patients with HCC and 39.5% of controls had elevated CRP values (> 6 microg/mL). Although using elevated CRP and/or AFP (> 20 ng/mL) as a criterion showed a significant difference between controls and patients with multiple nodular, massive, or diffuse type HCC (all P < 0.005), the clinical application of this criterion was limited because of low specificity (58%) and accuracy (all < 73%). By using receiver-operating characteristic curves no valuable threshold value of CRP was found to discriminate various types of HCC, except for distinguishing the diffuse type from controls. The CRP value of 12 microg/mL could be used as the cut-off value to differentiate diffuse-type HCC from controls (sensitivity 82.4%, specificity 82%, accuracy 82.1%, P<0.005). CONCLUSIONS: Serum CRP is not a good marker for HCC. However, very high values of CRP in patients with cirrhosis may suggest the presence of a diffuse-type HCC.  相似文献

A prospective study was carried out in 126 cases with liver cirrhosis attending the outpatient clinic of Hepatology of the Department of Internal Medicine, Dr. Cipto Mangunkusmo Hospital Jakarta, between August 1,1982 and Dec. 31, 1985. The patients consisted of 82 men and 44 women and there were 45 HBsAg positive cases (36.7%). HBeAg was posotive in 35.6% (16/45) and 40.0% were antiHBe positive while both markers were negative in 24.4%. During the follow-up study 27 cases died. The cause of death was due to variceal bleeding in 9 cases (33.3%) and hepatic failure in 9 cases (33.3%). In 6 cases (22.2%) hepatocellular carcinoma (HCC) was the cause of death. Nine cases out of 94 traceable cases (13.7%) were developed HCC. They consisted of 4 cases out of 29 cases (13.8%) with HBsAg positive and 5 cases out of 65 cases (7.7% ). But no significant difference was observed between both groups. The length of observation period from the first time of diagnosis until development of HCC was from 1 to 6 years with an average of 2.9 years.

Abstract

Objective. To assess retrospectively whether continuously high serum alanine aminotransferase (ALAT) levels (<80 IU) in the first three successive years after the diagnosis of liver cirrhosis (LC) are predictive of a subsequent high incidence of hepatocellular carcinoma (HCC) in patients with Child Stage A hepatitis C virus (HCV)-LC. Material and methods. The study comprised 132 HCV-LC (Child Stage A) patients who had not received interferon therapy but had been treated with anti-inflammatory agents. At the end of a 3-year follow-up after the diagnosis of LC, the patients were subdivided into three groups according to their serum ALAT levels and the subsequent incidence of HCC was assessed. Results. The cumulative incidence of HCC starting from 3 years after the diagnosis of LC in the continuously high ALAT group (annual average over 3 years always ≥80 IU; n=41; Group A) was markedly higher than that in the continuously low ALAT group (always <80 IU; n=48; Group B) (p<0.005) during an observation period of 7.9±3.7 years. The incidence of HCC in Group A was 11.8%/year. The odds ratios of developing HCC in Group A and Group C (mixed high and low ALAT levels; n=43) were 5.1-fold and 1.5-fold that of Group B, respectively. A multivariate analysis revealed that the ALAT group was independently associated with HCC development. Conclusions. Continuously high ALAT levels for three successive years following the diagnosis of LC can be predictive of a very high incidence of HCC in Child A HCV-LC patients. Prospective trials using therapeutic approaches aimed at decreasing ALAT levels are necessary in order to confirm a positive impact of ALAT reduction on the incidence of HCC in patients with HCV-LC.  相似文献

Partial splenic embolization (PSE) was performed on patients with liver cirrhosis to control hypersplenism and gastroesophageal varices. In this study, we evaluated the effects of PSE on the portal hemodynamics and hepatic function of 17 cirrhotic patients with hepatocellular carcinoma. The mean splenic volume and the peak platelet count increased significantly and the splenic vein pressure decreased significantly after PSE. However, the portal blood flow did not change. Changes in the 15-min retention rate of indocyanine green and the arterial ketone body ratio were not significant, but the redox tolerance index increased from 0.24 ± 0.28 × 10?2 to 0.59 ± 0.35 × 10?2. These results suggest that PSE may reduce perioperative risks in cirrhotic patients with hepatocellular carcinoma who are candidates for hepatic resection.  相似文献

OBJECTIVES: To ascertain serum and tissue expression of des‐gamma‐carboxyprothrombin (DCP) in patients with hepatocellular carcinoma (HCC) and liver cirrhosis and clarify the relationship between DCP expression and prognosis. METHODS: Expression of DCP in tissues was evaluated with immunohistochemical staining using anti‐DCP antibody in 74 patients with a single primary HCC nodule and liver cirrhosis. Their serum DCP levels were determined using an enzyme immunoassay with a double antibody sandwich system. RESULTS: Positive DCP expression in cancerous and non‐cancerous tissues was related to a worse prognosis for patients with HCC and liver cirrhosis. The combined evaluation of tissue DCP expression and serum DCP level showed that prognosis was the worst for patients with positive tissue DCP expression and a high serum DCP level. Univariate analysis indicated that a lower 5‐year survival rate was significantly correlated with positive tissue DCP expression, a high serum DCP level and the combined factor of positive tissue DCP expression and a high serum DCP level. Multivariate analysis indicated that the combined factor of positive tissue DCP expression and a high serum DCP level was a significant prognostic factor. CONCLUSION: The combined evaluation of tissue DCP expression and serum DCP level is more useful than either factor alone in predicting prognosis for patients with HCC and liver cirrhosis.  相似文献

Hepatocellular carcinoma is one of the most frequent forms of cancer worldwide and its diagnosis and treatment have changed substantially during the last few years. Recent advances in ultrasonography, spiral computed tomography scan and nuclear magnetic resonance have further simplified the diagnostic approach to hepatocellular carcinoma. Ultrasonography is the reference examination, giving a wide variety of information on tumour size, location, relationship with portal and hepatic veins and splanchnic haemodynamics. Surgical resection and liver transplantation can both be defined as curative treatment while other techniques such as percutaneous ethanol injection and chemoembolization must be considered as palliative. Therapeutic strategies for hepatocellular carcinoma are based upon data concerning the characteristics of the tumour the functional status of non-tumoural liver parenchyma and patients' general conditions. Surgery of hepatocellular carcinoma in cirrhotic liver is mainly restricted by lack of functional hepatic reserve and by the limited capacity of hepatic regeneration. The best surgical results are obtained in early tumoural stages which generally need limited resection. Nevertheless, major liver resections have a specific role in selected cases. Recurrence rate after surgical resection is high and is related to a large number of factors. For this reason, liver transplantation, removing at the same time, the tumour and the underlying disease, is considered, theoretically, the best treatment for hepatocellular carcinoma, but its role is still debated and limited by difficult organ sharing. Integration of present therapeutic schemes are under evaluation with promising preliminary results.  相似文献

Aim:  To investigate the proportion of patients with alcoholic cirrhosis who abstained from alcohol after contact with a hepatology unit, the predictors for abstinence, and the role of clinical and psychosocial factors in short-term mortality in these patients.
Methods:  Eighty-seven consecutive patients with alcoholic cirrhosis from a transplant center were included. Data on cirrhosis severity and complications, as well as on abstinence and psychosocial factors were collected. Patients were followed up for 19 (12–25) months. Data on abstinence during follow up, alcohol abuse treatment, psychiatric contact, severity of cirrhosis, mortality, and liver transplantation were analyzed.
Results:  Prior to inclusion, 53/87 (61%) patients had abstained from alcohol for 24 months (interquartile range: 18–33). Twenty percent had a history of other substance abuse, 47% had undergone alcohol abuse treatment, and 21% had a previous psychiatric diagnosis. Forty-eight percent lived with a partner, 23% worked/studied, and 53% were pensioners. During follow up, 26% died, 20% received a liver transplant, 55% abstained from alcohol, 47% received alcohol abuse treatment, and 33% had psychiatric contact. In a multivariate analysis, abstinence during follow up was found to be related to abstinence upon inclusion in the study, to the model for end-stage liver disease (MELD) score at follow up, and to no abuse treatment in a detoxification unit, whereas mortality was related to index MELD and alcohol abuse treatment during follow up. Neither abstinence nor mortality was related to psychosocial factors.
Conclusion:  More than half of patients with alcoholic cirrhosis were found to abstain from alcohol during follow up, which was related to prior documentation of abstinence and cirrhosis severity. Cirrhosis severity (expressed as the MELD) and alcohol abuse treatment during follow up were related to short-term mortality.  相似文献

Nonalcoholic fatty liver disease (NAFLD) is classified as nonalcoholic steatohepatitis (NASH) or simple steatosis (SS) according to histological findings. It is well recognized that NASH may develop into cirrhosis and hepatocellular carcinoma (HCC), both with unfavorable prognoses. Although the outlook of SS is reported to be better than that of NASH, the long-term prognosis of SS remains unclear. Here, we report the case of a patient who was diagnosed as having SS by a first liver biopsy, and later developed into cirrhosis and HCC over a period of 27 years. In 1980, a 42-year-old Japanese man was admitted because of abnormal liver function tests. He had no history of alcohol intake and was negative for hepatitis virus markers and autoantibodies. A liver biopsy specimen showed macrovesicular steatosis without ballooned hepatocytes, Mallory hyaline, lobular inflammation, or perisinusoidal/perivenular fibrosis, confirming the diagnosis of SS. The patient’s serum aminotransferase levels did not normalize despite repeated dietary instruction, and in 2001, liver histology demonstrated cirrhosis with mild steatosis and hepatocyte ballooning, leading to the diagnosis of NASH-related cirrhosis. HCC appeared in 2007. Overall, this patient progressed to cirrhosis and HCC in 20 and 27 years, respectively, following initial diagnosis. Platelet counts and degree of steatosis, as assessed by periodic ultrasonography, were seen to gradually reduce with progression of fibrosis. This case demonstrates that even a diagnosis of SS does not guarantee non-progression to cirrhosis and HCC, and careful follow-up is needed not only in patients with NASH, but also in those with SS.  相似文献

AIM: To assess the role of hepatitis B virus (HBV), hepatitis C virus (HCV) and alcohol intake as risk factors for hepatocellular carcinoma (HCC) in the presence or absence of cirrhosis in Indian population. METHODS: A total of 213 patients with HCC and 254 control subjects not affected with hepatic diseases or neoplasm were recruited. Odds ratios (ORs) were estimated for each risk factor and synergism among various risk factors was also studied. RESULTS: The ORs and 95% confidence intervals (CI) of HCC were 48.02 (25.06-91.98) for any HBV marker, 38.98 (19.55-77.71) for HBsAg positivity, 12.34 (2.84-53.61) for HBsAg negative and antibody positive (either of anti-HBe or total anti-HBc), 5.45 (2.02-14.71) for anti-HCV positive and HCV RNA positive, and 2.83 (1.51-5.28) for heavy alcohol use. No significant risk increase was evident for subjects who were anti-HCV positive and HCV RNA negative. Synergism between alcohol and HCV infection in causing HCC was found, but not between alcohol and HBV. Overall, conclusive evidence of the presence or absence of cirrhosis was reached in 189 (88.73%) HCC patients; cirrhosis was present in 137 (72.48%) of them. ORs with 95% CI of HCC in the presence and absence of cirrhosis, respectively, for HBV were as follows: (i) 48.90 (24.61-97.19) and 35.03 (15.59-78.66) for any HBV marker; (ii) 39.88 (19.41-81.97) and 24.40 (10.60-56.18) for HBsAg positivity; and (iii) 12.10 (2.67-54.88) and 19.60 (3.94-97.39) for HBsAg negativity and antibody positivity. Significantly increased risk was found among cirrhotic patients for anti-HCV positivity and HCV RNA positivity [OR = 7.53 (2.73-20.78)] and for heavy alcohol use [OR = 3.32 (1.70-6.47)]; however, in the absence of cirrhosis, no significant risk increase was evident for subjects who were anti-HCV positive and HCV RNA positive [OR = 0.97 (0.11-8.54)], or who had history of heavy alcohol use [OR = 1.58 (0.55-4.53)]. CONCLUSIONS: Infection with HBV and HCV are the major risk factors for the development of HCC in Indian patients. Presence of HBV antibodies even in the absence of HBsAg conferred increased risk for HCC in the presence or absence of cirrhosis. Anti-HCV positivity in the absence of HCV RNA conferred no increased risk. HCV RNA positivity and heavy alcohol use significantly increased the risk of HCC among cirrhotic patients, but not non-cirrhotic patients.  相似文献

The present study was undertaken to elucidate clinicopathological findings and operative results of HCC with HB-associated cirrhosis, compared with those in HCC patients with alcoholic and post-transfusion cirrhosis. The number of the HBV group was 26 cases, consisting of 17 in sAg(+), 4 in eAg(+) and 5 in eAb(+) subgroups. The number of the post-transfusion group was 7 and that of alcoholic group was 12. A high incidence of hypersplenism and esophageal varix in the eAg(+) subgroup was found. ICG R15 was the highest, Kicg and ICG Rmax were the lowest in the eAg(+) subgroup. The mean diameter of tumors was the largest, 6.6±3.9 cm, in the sAg(+) subgroup and was the smallest, 2.2+1.7 cm, in the eAg(+) subgroup. The incidence of postoperative jaundice, hyperammoninemia and live dysfunction were the highest in the sAg(+) and eAg(+) subgroup. One and three-year survival rate were 76.9% and 48.1% in the sAg(+) subgroup, 60.0% and 30.0% in the eAb(+) subgroup, and the oneyear survival rate in the eAg(+) subgroup was 50.0%. The three-year survival rate could not be calculated because 3 years had not passed since the operation. The prognosis was the poorest in the HBV group among all groups. This study suggests that in HBV-associated cirrhosis, hepatectomy might induce “acute on chronic” changes (acute hepatitis and fulminant hepatitis). Therefore we should select operative procedures by considering surgical risk and the etiology of liver cirrhosis in hepatectomy.  相似文献
