Abstract
BACKGROUND Hepatocellular carcinoma (HCC) occurs mostly in people with chronic liver disease and ranks sixth in terms of global instances of cancer, and fourth in terms of cancer deaths for men. Despite that abdominal ultrasound (US) is used as an initial test to exclude the presence of focal liver lesions and serum alpha-foetoprotein (AFP) measurement may raise suspicion of HCC occurrence, further testing to confirm diagnosis as well as staging of HCC is required. Current guidelines recommend surveillance programme using US, with or without AFP, to detect HCC in high-risk populations despite the lack of clear benefits on overall survival. Assessing the diagnostic accuracy of US and AFP may clarify whether the absence of benefit in surveillance programmes could be related to under-diagnosis. Therefore, assessment of the accuracy of these two tests for diagnosing HCC in people with chronic liver disease, not included in surveillance programmes, is needed. OBJECTIVES Primary: the diagnostic accuracy of US and AFP, alone or in combination, for the diagnosis of HCC of any size and at any stage in adults with chronic liver disease, either in a surveillance programme or in a clinical setting. Secondary: to assess the diagnostic accuracy of abdominal US and AFP, alone or in combination, for the diagnosis of resectable HCC; to compare the diagnostic accuracy of the individual tests versus the combination of both tests; to investigate sources of heterogeneity in the results. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Hepato-Biliary Group Diagnostic-Test-Accuracy Studies Register, Cochrane Library, MEDLINE, Embase, LILACS, Science Citation Index Expanded, until 5 June 2020. We applied no language or document-type restrictions. SELECTION CRITERIA Studies assessing the diagnostic accuracy of US and AFP, independently or in combination, for the diagnosis of HCC in adults with chronic liver disease, with cross-sectional and case-control designs, using one of the acceptable reference standards, such as pathology of the explanted liver, histology of resected or biopsied focal liver lesion, or typical characteristics on computed tomography, or magnetic resonance imaging, all with a six-months follow-up. DATA COLLECTION AND ANALYSIS We independently screened studies, extracted data, and assessed the risk of bias and applicability concerns, using the QUADAS-2 checklist. We presented the results of sensitivity and specificity, using paired forest-plots, and tabulated the results. We used a hierarchical meta-analysis model where appropriate. We presented uncertainty of the accuracy estimates using 95% confidence intervals (CIs). We double-checked all data extractions and analyses. MAIN RESULTS We included 373 studies. The index-test was AFP (326 studies, 144,570 participants); US (39 studies, 18,792 participants); and a combination of AFP and US (eight studies, 5454 participants). We judged at high-risk of bias all but one study. Most studies used different reference standards, often inappropriate to exclude the presence of the target condition, and the time-interval between the index test and the reference standard was rarely defined. Most studies with AFP had a case-control design. We also had major concerns for the applicability due to the characteristics of the participants. As the primary studies with AFP used different cut-offs, we performed a meta-analysis using the hierarchical-summary-receiver-operating-characteristic model, then we carried out two meta-analyses including only studies reporting the most used cut-offs: around 20 ng/mL or 200 ng/mL. AFP cut-off 20 ng/mL: for HCC (147 studies) sensitivity 60% (95% CI 58% to 62%), specificity 84% (95% CI 82% to 86%); for resectable HCC (six studies) sensitivity 65% (95% CI 62% to 68%), specificity 80% (95% CI 59% to 91%). AFP cut-off 200 ng/mL: for HCC (56 studies) sensitivity 36% (95% CI 31% to 41%), specificity 99% (95% CI 98% to 99%); for resectable HCC (two studies) one with sensitivity 4% (95% CI 0% to 19%), specificity 100% (95% CI 96% to 100%), and one with sensitivity 8% (95% CI 3% to 18%), specificity 100% (95% CI 97% to 100%). US: for HCC (39 studies) sensitivity 72% (95% CI 63% to 79%), specificity 94% (95% CI 91% to 96%); for resectable HCC (seven studies) sensitivity 53% (95% CI 38% to 67%), specificity 96% (95% CI 94% to 97%). Combination of AFP (cut-off of 20 ng/mL) and US: for HCC (six studies) sensitivity 96% (95% CI 88% to 98%), specificity 85% (95% CI 73% to 93%); for resectable HCC (two studies) one with sensitivity 89% (95% CI 73% to 97%), specificity of 83% (95% CI 76% to 88%), and one with sensitivity 79% (95% CI 54% to 94%), specificity 87% (95% CI 79% to 94%). The observed heterogeneity in the results remains mostly unexplained, and only in part referable to different cut-offs or settings (surveillance programme compared to clinical series). The sensitivity analyses, excluding studies published as abstracts, or with case-control design, showed no variation in the results. We compared the accuracy obtained from studies with AFP (cut-off around 20 ng/mL) and US: a direct comparison in 11 studies (6674 participants) showed a higher sensitivity of US (81%, 95% CI 66% to 90%) versus AFP (64%, 95% CI 56% to 71%) with similar specificity: US 92% (95% CI 83% to 97%) versus AFP 89% (95% CI 79% to 94%). A direct comparison of six studies (5044 participants) showed a higher sensitivity (96%, 95% CI 88% to 98%) of the combination of AFP and US versus US (76%, 95% CI 56% to 89%) with similar specificity: AFP and US 85% (95% CI 73% to 92%) versus US 93% (95% CI 80% to 98%). AUTHORS' CONCLUSIONS In the clinical pathway for the diagnosis of HCC in adults, AFP and US, singularly or in combination, have the role of triage-tests. We found that using AFP, with 20 ng/mL as a cut-off, about 40% of HCC occurrences would be missed, and with US alone, more than a quarter. The combination of the two tests showed the highest sensitivity and less than 5% of HCC occurrences would be missed with about 15% of false-positive results. The uncertainty resulting from the poor study quality and the heterogeneity of included studies limit our ability to confidently draw conclusions based on our results.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a typical hypervascular tumor. The utility of serum alpha-fetoprotein (α-FP) in its detection is questionable. Over-expression and high circulating levels of insulin-like growth factor-II (IGF-II) were reported in tissue and in serum of patients with HCC. We investigated the diagnostic application of IGF-II in the diagnosis of HCC. METHODS Serum IGF-II and α-FP levels were measured in 178 patients (82 with HCC and 96 with liver cirrhosis) and in 30 healthy controls. Spearman test, non parametric combination test and confidence interval analysis were used for statistical evaluation of data. RESULTS The best cut-off values selected by ROC curves were 796 ng/ml for IGF-II and 132 ng/ml for α-FP. IGF-II mean values were higher in patients with HCC than in those with liver cirrhosis (LC) (p=0.0001) but lower in LC than in controls (p=0.0001). Serum IGF-II levels above cut-off were found in 22% of patients with HCC, in 9.3% of those with cirrhosis and in 20% of controls. α-FP serum levels >132 ng/ml were observed in 48% of HCC, in 3.1% of LC and in none of control group. By correlation study, serum IGF-II levels were significantly correlated with serum α-FP levels (r=0.427, p=0.0001) and with nodules' diameter (r=0.252, p=0.0130) but not with nodules' number (p>0.050). Finally, IGF-II showed lower sensitivity, specificity and predictive values than α-FP. CONCLUSION Circulating IGF-II is not a useful marker for HCC. Further researches are however needed to evaluate its diagnostic accuracy before and after nutritional adjustment.

Abstract
INTRODUCTION Alpha-fetoprotein (AFP) is an oncofetal protein produced by hepatocellular carcinoma (HCC). AFP level can also be elevated in other neoplastic or non-neoplastic conditions. An elevated AFP level has high diagnostic significance for HCC; at a level of >200 ng/mL, the probability of HCC is >90%. The aim of the present paper is to report a patient who underwent curative resection of HCC, who had a persistently elevated AFP level postoperatively but did not develop recurrence during a 2-year follow-up period. A review of the literature is also presented. CASE REPORT An 82-year-old male was referred following a computed tomography scan showing a 160 mm diameter mass in the left lobe of the liver. This huge mass was diagnosed as HCC, arising in the absence of cirrhosis or viral hepatitis. After tumor removal, the patient's high AFP level persisted for 2 years. CONCLUSION As steatosis was the only pathological change in the remnant liver, this may have caused the persistently elevated AFP level in this patient.

Abstract
BACKGROUND AND STUDY AIMS Early diagnosis of hepatocellular carcinoma (HCC) is the only hope for cure. Although the role of alpha foetoprotein (AFP) in the diagnosis of advanced HCC is well recognised, at least one-third of cases will be missed unless another diagnostic tool is used. Increased levels of circulating interleukin-18 (IL-18) have been observed in patients with several cancer types and were described in patients with chronic hepatitis. The aim of this study is to assess the role of serum IL-18 level in the diagnosis of hepatitis C virus (HCV)-related HCC. PATIENTS AND METHODS A total of 75 subjects categorised into four groups, including 25 patients with HCV-related HCC and AFP above 200ng/ml, 25 patients with HCV-related HCC and AFP below 200ng/ml, 15 patients with HCV-related chronic liver disease and 10 healthy controls, were enrolled. HCC was diagnosed according to guidelines of the American Association for the Study of Liver Diseases. AFP and IL-18 were assessed in all subjects. RESULTS AFP and IL-18 levels are significantly higher in patients with HCC than in disease control and healthy control subjects. IL-18 level is not correlating with the size or the number of hepatic focal lesions neither with the presence of lymphovascular invasion or abdominal lymphadenopathy. The best cut-off value of IL-18 for the diagnosis of HCC is 500pg/ml with 84% sensitivity and 86.7% specificity and the area under receiver operating characteristic curve is 0.675. CONCLUSION Serum IL-18 level is a suitable marker for the diagnosis of HCV-related HCC complementary to AFP, especially in cases with AFP level less than the diagnostic value.

Abstract
Hepatocellular carcinoma is one of the most common malignant human tumors. Hepatocarcinogenesis is a multistep process with a multifactorial etiology. Chronic hepatitis B and hepatitis C virus infection, alcohol drinking and cirrhosis of any etiology are the major risk factors for hepatocellular carcinoma. Growth factors, their receptors and related proteins are involved in the process of malignant transformation. The IGF axis is involved in the proliferation and differentiation of normal, transformed and malignant hepatocytes. In the context of hepatocarcinogenesis, IGF-II has, in particular, been investigated thoroughly. Increased IGF-II bioavailability, protease activity of IGF-binding proteins and IGF-I receptor expression, decreased expression of IGF-II receptor and IGF-binding proteins are thought to contribute to hepatocellular carcinoma genesis. This review will first focus on the role of the IGF axis in hepatocarcinogenesis. In the second part it will emphasize circulating IGF-II levels in chronic liver disease and hepatocellular carcinoma, and diagnostic application of serum IGF-II level in both small and larger hepatocellular carcinoma.

Abstract
Background and aims The role of alphafetoprotein (AFP) in the diagnosis and surveillance of hepatocellular carcinoma (HCC) is getting smaller owing to the advances in imaging modalities. The aims of this study were to assess the diagnostic accuracy of tumor markers in small HCC and to find the optimal cutoff value of each tumor marker for efficient surveillance. Methods Studies in all languages were identified by searching MEDLINE from 1982 to 2002. Studies were included when they showed sensitivity and specificity for HCCs 5 cm or smaller and recruited only patients with chronic hepatitis or liver cirrhosis as control. We assessed diagnostic odds ratios (DORs) for the evaluation of diagnostic accuracy of tumor markers and positive likelihood ratios (LRs+) to find the optimal cutoff value. DORs and LRs+ were combined according to the random effect model. The summary receiver operating characteristics (ROC) curve was also assessed. Results Seventeen articles on three tumor markers-AFP, des-gamma-carboxyprothrombin (DCP), and Lens culinaris agglutinin-reactive fraction of AFP (AFP-L3)-were enrolled after full-text evaluation. AFP was inferior to DCP and AFP-L3 in both DOR (4.50 vs. 8.16 and 10.50) and area under the ROC curve (0.647 vs. 0.688 and 0.695). Optimal cutoff values that provide the best LR+ were 200 ng/ml for AFP, 40 mAU/ml for DCP, and 15% for AFP-L3. Conclusions Diagnostic accuracy of AFP in small HCC was substantially limited. Surveillance including other tumor markers with optimal cutoff value should be conducted to confirm the efficacy of the policy.

Abstract
OBJECTIVE Alpha-fetoprotein (AFP) is not a useful tumor marker for diagnosis of small hepatocellular carcinoma (HCC). There is over-expression of insulin-like growth factor (IGF)-II in HCC tissue. This study investigates the diagnostic application of IGF-II in small HCC. MATERIAL AND METHODS Serum levels of IGF-II and AFP were determined in 41 patients with small cirrhotic HCC (< or = 3 cm), 41 sex- and age-matched patients with cirrhosis alone (LC), and 41 healthy adults. The optimal cut-off values for diagnosing HCC were determined with receiver operating characteristics (ROC) curve. RESULTS Both IGF-II and AFP levels in HCC were higher than those in LC patients or controls (each p = 0.0001). The IGF-II levels in LC patients were lower than those in controls (p = 0.001). In HCC patients, multivariate analysis indicated that that both IGF-II (odds ratio, 4.54; 95% confidence interval, 2.15-9.55; p = 0.0001) and AFP (odds ratio, 1.05; 95% confidence interval, 1.01-1.08; p = 0.003) were found to be associated with an increased risk of presence of HCC. The optimal cut-off values of IGF-II (4.1 mg/g prealbumin) and AFP (50 ng/ml) were determined with ROC curves. The sensitivity, specificity, and diagnostic accuracy values for IGF-II were 63%, 90%, and 70%, respectively. Those for AFP were 44%, 95%, and 70%, respectively. Determination of both markers in parallel significantly increase the diagnostic accuracy (88%) and sensitivity (80%), with a high specificity (90%). CONCLUSIONS Serum IGF-II level can be used as an independent serologic marker or a complementary tumor marker to AFP for diagnosis of small HCC.

Abstract
The cancer recognition (CARE) antibody (Ab) test is a serologic assay for a specific IgM that is elevated in cancer patients. All tests are measured using an indirect enzyme-linked immunosorbent assay (ELISA) of human serum. The target polypeptide in the CARE Ab test is the IgM binding epitope (LT-11) of the CARE antigen (Ag) consisting of a 16 mer structure that has been produced synthetically. The mean relative concentration (MRC) is determined relative to standard, normalized human plasma. Non-parametric analysis showed median MRC values of healthy volunteers (HVs) with no history of cancer (n =47), family history of cancer (n = 126) and a previous cancer history (n = 24) to be 26, 34 and 46, respectively. It was determined that there was no significance found among the medians of the three HV groups (P = 0.53). The specificity of the HV types was between 87 and 98%. Benign/non-cancer surgical patients (n = 27) had a median value of 20 with a specificity of 96%. The cancer patients (n = 61) had a median value of 246 with a sensitivity of 89%. There was a significant difference between the HV and cancer patients (P < 0.0001) as well as between the benign/surgical non-cancerous group and cancer patients (P < 0.0001). The IgM antibody is heat stable at room temperature for two days versus being frozen at -80 degrees C (r2 = 0.97). Either serum or plasma samples may be used in the CARE Ab test (r2 = 0.92). The CARE Ab was almost exclusively IgM with no serum conversion to IgG in sequential measurements of patients with cancer over a six-month period. Preliminary data from patients undergoing post-operative cancer treatment showed that decreasing Ab levels revealed patients negative for residual cancer or undergoing remission, while relapsing patients show an increase in Ab levels. A return to a positive Ab level shortly after treatment is a poor prognostic sign while in advanced cancers the Ab levels may be depressed significantly.

Abstract
This systematic review addresses the following questions: (1) What is the efficacy of using screening tests for hepatocellular carcinoma (HCC) in improving outcomes in chronic hepatitis C, and (2) what are the sensitivity and specificity of screening tests for HCC in chronic hepatitis C? The search strategy involved searching Medline and other electronic databases between January 1985 and March 2002. Additional articles were identified by reviewing pertinent articles and journals and by querying experts. Articles were eligible for review if they reported original human data from studies of screening tests that used virological, histological, pathologic, or clinical outcome measures. Data collection involved paired reviewers who assessed the quality of each study and abstracted data. One nonrandomized prospective cohort study suggested that HCC was detected earlier and was more often resectable in patients who had twice yearly screening with serum alpha-fetoprotein (AFP) and hepatic ultrasound than in patients who had usual care. Twenty-four studies, which included patients with chronic hepatitis C or B or both, addressed the sensitivities and specificities of screening tests. They were relatively consistent in showing that the sensitivity of serum AFP for detecting HCC usually was moderately high at 45% to 100%, with a specificity of 70% to 95%, for a threshold of between 10 and 19 ng/mL. The few studies that evaluated screening with ultrasound reported high specificity, but variable sensitivity. In conclusion, screening of patients with chronic hepatitis C with AFP and ultrasound may improve detection of HCC, but studies are needed to determine whether screening improves clinical outcomes.

Abstract
For assessing the role of circulating immune complexes (CIC) in chronic hepatitis B virus (HBV) infection, CICs containing IgM, IgG, and HBsAg were determined by C1q and conglutinin (K) assays in 216 patients with chronic HBV infection and 54 healthy controls. The concentration of each type of CIC in patients is higher than in controls (P = 0.0001). CIC is a common feature of chronic HBV infection with 95.8% of cases having at least one abnormal test result. At least one type of HBsAg-CIC is positive in 54.2% of patients. HBsAg-CIC positivity is associated with HBeAg positivity (P = 0.0001), higher aminotransferase levels (P < 0.002), and younger age (P = 0.001). IgG-CIC or IgM-HBsAg-CIC correlates with higher aminotransferase activity (P = 0.001). In conclusion, HBsAg-CIC correlates with HBV replication. IgG-CIC and/or IgM-HBsAg-CIC correlate with disease activity. Immune-mediated injury may play a role in the pathogenesis of chronic HBV infection.

Abstract
To assess the clinical relevance of transforming growth factor-beta 1 (TGF-beta 1) in the urine of patients with hepatocellular carcinoma (HCC), TGF-beta 1 was measured, by radioimmunoassay, in 140 patients with HCC, 50 cirrhotic patients, 30 patients with chronic active hepatitis, and 50 healthy controls. The results indicate that there were significantly increased urinary TGF-beta 1 levels in patients with HCC. Raised TGF-beta 1 levels were associated, in a dose-related fashion, with increased risk for development of HCC (odds ratio, 1.05, 95% confidence interval, 1.03-1.07). HCC patients with raised TGF-beta 1 levels had shorter survival than those with normal TGF-beta 1 levels (p = 0.038). TGF-beta 1 levels decreased after successful anticancer therapy (p < 0.0001). There was an inverse correlation between TGF-beta 1 and serum alpha-fetoprotein (AFP) (r = -0.199, p < 0.04). Receiver operating characteristics (ROC) curve analysis indicated that parallel determination of TGF-beta 1 and AFP significantly increased the sensitivity and diagnostic accuracy, with a high specificity. In conclusion, raised urinary TGF-beta 1 was associated with HCC development. It is a predictor of poor prognosis, and a tumor marker for diagnosis and therapeutic follow-up of HCC.

Abstract
BACKGROUND Our aim was to assess the relationship between transforming growth factor beta 1 (TGF-beta 1) and alpha-fetoprotein (AFP) levels in hepatocellular carcinoma (HCC). METHODS Urinary TGF-beta 1 and serum AFP were determined in 123 HCC patients, 50 patients with chronic liver disease (CLD), and 50 healthy controls. RESULTS Both TGF-beta 1 and AFP levels were higher in HCC patients than in CLD patients or controls (each, P = 0.0001). There was a negative correlation between TGF-beta 1 and logAFP (r = -0.196, P = 0.029). Multivariate analysis indicated that TGF-beta 1 and AFP were associated with an increased risk of HCC development. By receiver-operating characteristic curve analysis, determination of AFP and TGF-beta 1 in parallel significantly increased the sensitivity and diagnostic accuracy in detecting HCC. CONCLUSION Increased urinary TGF-beta 1 level can be used as a complementary marker to AFP for detection of HCC with low AFP production.

Abstract
To assess the clinical relevance of transforming growth factor-beta1 (TGF-beta1) in hepatocellular carcinoma (HCC), urinary TGF-beta1 and serum alpha-fetoprotein (AFP) were determined in 94 patients with cirrhotic HCC, 94 age- and sex-matched patients with cirrhosis alone and 50 healthy adults. TGF-beta1 level in HCC was higher than in cirrhosis alone or in healthy controls (each P = 0.0001). There is an inverse correlation between TGF-beta1 and AFP levels (r = -0.292, P = 0.004). Significantly higher TGF-beta1 level was found in HCC patients with worsening Child-Pugh stages, diffuse HCC, tumour size > 3 cm, multilobular tumour and AFP < or = 20 ng ml(-1). TGF-beta1 level decreased after complete treatment with transcatheter arterial chemoembolization (P = 0.0001). The median survival in HCC patients with raised TGF-beta1 was shorter than those with normal TGF-beta1 (P = 0.018). Multivariate analysis indicated that TGF-beta1 and AFP were significantly correlated with the presence of HCC. In addition, TGF-beta1 could be used as a diagnostic marker for HCC, particularly in tumours with low AFP production. In conclusion, elevated urinary TGF-beta1 level is a tumour marker and predictor of poor survival for cirrhotic HCC.

Abstract
To evaluate the diagnostic application of urinary transforming growth factor-beta1 (TGF-beta1) and serum alpha-fetoprotein (AFP) levels in hepatocellular carcinoma (HCC), TGF-beta1 and AFP were determined in 94 patients with cirrhotic HCC and in 94 sex- and age-matched patients with cirrhosis alone. TGF-beta1 and AFP levels in HCC were higher than in cirrhosis alone (P = 0.0001). There is an inverse correlation between TGF-beta1 and log AFP (r = -0.292, P = 0.004). Multivariate analysis indicated that TGF-beta1 and AFP were closely associated, in a dose-related fashion, with the development of HCC. Receiver-operating characteristic (ROC) curves were used to determine the optimal cut-off values of TGF-beta1 (50 microg g(-1) creatinine) and AFP (100 ng ml(-1)). Both TGF-beta1 and AFP showed a high specificity (99%) and positive likelihood ratio. The sensitivity was 53.1% for TGF-beta1 and 55.3% for AFP. The determination of both markers in parallel significantly increased the diagnostic accuracy (90.1%) and sensitivity (84%), with a high specificity (98%) and positive likelihood ratio (40.0). In conclusion, TGF-beta1 and AFP are independent tumour markers of HCC and may be used as complementary tumour markers to discriminate HCC from cirrhosis.

Abstract
Cathepsin D serum mass concentrations were determined by enzyme immunoassay in patients with hepatocellular carcinoma (n = 51) and/or liver cirrhosis (n = 92) or benign steatosis (n = 16) and correlated with some biochemical and clinical properties of these diseases. Increased cathepsin D serum mass concentrations (P < 0.001) were observed in all these groups of patients as compared to normal subjects (n = 98). However, patients with steatosis had serum mass concentrations of this enzyme significantly lower (mean 2-3 fold) than those measured in cancer patients (P < 0.05) or cirrhotic patients (P < 0.001). Interestingly, significantly higher cathepsin D serum mass concentrations (mean + 62%) (P < 0.006) were determined in the cirrhosis group as compared to cancer patients. No correlation between cathepsin D and a number of clinical and biochemical properties examined, namely, alpha-foetoprotein, number of neoplastic lesions and tumour size in cancer patients or, Child-Pugh grade of severity of cirrhosis and other enzymes of liver function tests in the cirrhotic group was found. The present data and those from other studies which indicate that cathepsin D may be involved in carcinogenesis suggest that this enzyme may be potentially useful as an additional biochemical marker to identify cirrhotic patients who may develop precancerous hepatic nodules.

Abstract
To assess the role of hepatitis B e antigen (HBeAg) and its interaction with hepatitis B surface antigen (HBsAg) on the development of hepatocellular carcinoma (HCC), this case-control study included 361 age- and sex-matched pairs of patients with histologically proven HCC and healthy control subjects. HBsAg, HBeAg and antibody to HBeAg (anti-HBe) were detected by radioimmunoassay. Antibodies to hepatitis C virus (anti-HCV) were detected by second-generation enzyme immunoassay. The prevalences of HBeAg (20.2%), HBsAg (80.3%) and anti-HCV (29.5%) in cases were higher than in controls (1.9%, 20.7%, and 2.7% respectively; each P < 0.0001). Using patients negative for HBsAg, HBeAg and anti-HBe as a referent group, univariate analysis indicated that HBsAg alone or HBsAg and HBeAg were risk factors for HCC (P for trend < 0.0001). Calculation of incremental odds ratio indicated that there was additive interaction between HBsAg and HBeAg. Multivariate analysis indicated that HCC development was strongly associated with the presence of HBeAg (odds ratio, 8.1; 95% confidence interval, 2.4-27.1), HBsAg (odds ratio, 68.4; 95% confidence interval, 20.5-227.8) and anti-HCV (odds ratio, 59.3; 95% confidence interval, 13.6-258.4). In conclusion, HBsAg, HBeAg and anti-HCV are independent risk factors for HCC. There is additive and independent effect modification between HBsAg and HBeAg on the development of HCC.
