Hepatocellular carcinoma in patients without cirrhosis in Italy.

BACKGROUND: In the Western world, hepatocellular carcinoma seldom develops in patients without cirrhosis, and reports describing the characteristics of non-cirrhotic patients with hepatocellular carcinoma are rather infrequent. METHODS: We evaluated the main clinical characteristics, treatment options, and survival of patients with hepatocellular carcinoma developed in non-cirrhotic liver among the 3027 consecutive cases of hepatocellular carcinoma accrued in the Italian Liver Cancer database during the last 20 years. RESULTS: We identified 52 patients with hepatocellular carcinoma in non-cirrhotic livers (1.7% of all hepatocellular carcinomas), 42 with (80.8%) and 10 without (19.2%) chronic liver disease. In patients without chronic liver disease, median tumour diameter was greater compared to patients with chronic liver disease (7.8 versus 4.0 cm, P=0.046). Curative treatment was feasible in 20 patients (38.5%). Median overall survival was 26 months and 5-year survival rate was 23.7%. Detection of hepatocellular carcinoma outside surveillance (P=0.036), advanced hepatocellular carcinoma stage (P<0.0001), and non-curative treatment (P=0.007) were associated with worse prognosis, but tumour stage was the only independent predictor of survival. CONCLUSIONS: In Italy, less than 2% of hepatocellular carcinomas develop in a non-cirrhotic liver, and almost never in a normal liver. These patients frequently present with advanced tumours, have low eligibility rates for curative treatment, and have a dismal prognosis despite their preserved liver function.

The changing scenario of hepatocellular carcinoma over the last two decades in Italy.

BACKGROUND & AIMS: This study investigates whether the aetiologic changes in liver disease and the improved management of hepatocellular carcinoma (HCC) have modified the clinical scenario of this tumour over the last 20 years in Italy. METHODS: Retrospective study based on the analysis of the ITA.LI.CA (Italian Liver Cancer) database including 3027 HCC patients managed in 11 centres. Patients were divided into 3 groups according to the period of HCC diagnosis: 1987-1996 (year of the "Milano criteria" publication), 1997-2001 (year of release of the EASL guidelines for HCC), and 2002-2008. RESULTS: The significant changes were: (1) progressive patient ageing; (2) increasing prevalence of HCV infection until 2001, with a subsequent decrease, when the alcoholic aetiology increased; (3) liver function improvement, until 2001; (4) increasing "incidental" at the expense of "symptomatic" diagnoses, until 2001; (5) unchanged prevalence of tumours diagnosed during surveillance (around 50%), with an increasing use of the 6-month schedule; (6) favourable HCC "stage migration", until 2001; (7) increasing use of percutaneous ablation; (8) improving survival, until 2001. CONCLUSIONS: Over the last 20 years, several aetiologic and clinical features regarding HCC have changed. The survival improvement observed until 2001 was due to an increasing number of tumours diagnosed in early stages and in a background of compensated cirrhosis, and a growing and better use of locoregional treatments. However, the prevalence of early cancers and survival did not increase further in the last years, a result inciting national policies aimed at implementing surveillance programmes for at risk patients.

Changing aetiological factors of hepatocellular carcinoma and their potential impact on the effectiveness of surveillance.

BACKGROUND: The aetiological factors of hepatocellular carcinoma may vary over time. AIMS: The study assessed the potential impact of the aetiological factors on the effectiveness of surveillance in real-world patients. METHODS: Multicentre, cross-sectional study enrolling consecutive hepatocellular carcinoma cases during a six month period. RESULTS: 1733 cases (1311 prevalent and 422 incident) were recruited (mean age 68.6 years; 46.1% cases over 70 years; 73.9% males; 95.3% with cirrhosis); 63.0% were hepatitis C virus positive and 23.7% were virus negative. Amongst incident HCCs, 34.5% were single ≤3cm and 54.4% met the Milan criteria; 61.6% were diagnosed during surveillance; virus negative patients showed the lowest rate of surveillance (51.0%). Surveillance was an independent predictor of detecting single HCCs ≤2cm (O.R.=5.4; 95% C.I.=2.4-12.4) or HCCs meeting the Milan criteria (O.R.=3.1; 95% C.I.=1.9-5.2). Compared with an earlier Italian survey, there was a higher proportion of elderly subjects (P<0.01), Child-Pugh class A cases (P<0.01), of virus-negative patients (P<0.01) and with single tumours ≤3cm (P<0.01) and a lower prevalence of hepatitis C virus positive individuals (P<0.01). CONCLUSION: HCC is characterised by a growing prevalence of elderly patients and cases unrelated to hepatitis virus infections. The application of surveillance must be implemented, particularly amongst non-viral patients.

Barcelona Clinic Liver Cancer staging and transplant survival benefit for patients with hepatocellular carcinoma: a multicentre, cohort study.

BACKGROUND: Allocation of deceased-donor livers to patients with chronic liver failure is improved by prioritising patients by 5-year liver transplantation survival benefit. The Barcelona Clinic Liver Cancer (BCLC) staging has been proposed as the standard means to assess for prognosis of patients with hepatocellular carcinoma. We aimed to create a prediction model linking the BCLC stage of patients with hepatocellular carcinoma to their 5-year liver transplant benefit. METHODS: A large cohort of consecutive patients with hepatocellular carcinoma (n=1328) from the ITA.LI.CA database (n=2951) were judged as potentially eligible for liver transplantation according to the following criteria: absence of macroscopic vascular invasion or metastases, age 70 years or younger, and absence of relevant extra-hepatic comorbidities. To assess the correlation between BCLC staging and non-liver transplantation survival, we did Cox univariate and multivariate analyses including the following covariates: BCLC stage, year of diagnosis, age, sex, cause of cirrhosis, model for end-stage liver disease score, α-fetoprotein concentrations, and treatment. Liver-transplantation survival benefit for patients was calculated, using Monte Carlo simulation analysis, as the patient's 5-year life expectancy with liver transplantation (estimated by the Metroticket model) minus the 5-year life expectancy without liver transplantation according to BCLC stage. FINDINGS: 83 (6%) of 1328 patients had BCLC 0 stage disease, 614 (46%) had BCLC A, 500 (38%) had BCLC B-C, and 131 (10%) had BCLC D. In the Cox non-liver transplantation survival multivariate model, hazard ratios associated with increasing BCLC stages were 1.530 (95% CI 1.107-2.116) for BCLC A versus BCLC 0, 1.572 (1.350-1.830) for BCLC B-C versus BCLC A, and 1.470 (1.164-1.856) for BCLC D versus BCLC B-C. Results of the Monte Carlo simulation analysis confirmed the significant effect of BCLC classification on transplant benefit; in the adjusted model, a median 5-year transplant benefit of 11.19 months (IQR 10.73-11.67) for BCLC 0, 13.49 months (11.51-15.57) for BCLC A, 17.36 months (15.06-19.28) for BCLC B-C, and 28.46 months (26.38-30.34) for BCLC D. INTERPRETATION: Liver transplantation could result in survival benefit for patients with hepatocellular carcinoma and advanced liver cirrhosis (BCLC stage D) and in those with intermediate tumours (BCLC stages B-C), regardless of the nodule number-size criteria (ie, Milan criteria), provided that macroscopic vascular invasion and extra-hepatic disease are absent. FUNDING: None.

Semiannual surveillance is superior to annual surveillance for the detection of early hepatocellular carcinoma and patient survival.

BACKGROUND & AIMS: The current guidelines recommend the surveillance of cirrhotic patients for early diagnosis of hepatocellular carcinoma (HCC), based on liver ultrasonography repetition at either 6 or 12 month intervals, since there is no compelling evidence of superiority of the more stringent program. This study aimed at comparing cancer stage, treatment applicability, and survival between patients on semiannual or annual surveillance. METHODS: We analyzed the clinical records of 649 HCC patients in Child-Pugh class A or B, observed in ITA.LI.CA centers. HCC was detected in 510 patients submitted to semiannual surveillance (Group 1) and in 139 submitted to annual surveillance (Group 2). In Group 1 the survival was presented as observed and corrected for the lead time. RESULTS: The cancer stage was less severe in Group 1 than in Group 2 (p<0.001), with more single tiny (2 cm) and less advanced tumors. Treatment applicability was improved by the semiannual program (p=0.020). The median observed survival was 45 months (95% CI 40.0-50.0) in Group 1 and 30 months (95% CI 24.0-36.0) in Group 2 (p=0.001). The median corrected survival of Group 1 was 40.3 months (95% CI 34.9-45.7) (p=0.028 with respect to the observed survival of Group 2). Age, platelet count, alpha-fetoprotein, Child-Pugh class, cancer stage, and hepatocellular carcinoma treatment were independent prognostic factors. CONCLUSIONS: Semiannual surveillance increases the detection rate of very early hepatocellular carcinomas and reduces the number of advanced tumors as compared to the annual program. This translates into a greater applicability of effective treatments and into a better prognosis.

Treatments for hepatocellular carcinoma in elderly patients are as effective as in younger patients: a 20-year multicentre experience.

OBJECTIVES: The number of elderly patients diagnosed with hepatocellular carcinoma (HCC) is expected to increase. We compared the presenting features and outcome of HCC in elderly (>or=70 years) and younger patients (<70 years). DESIGN: Multicentre retrospective cohort study and nested case-control study. Patients 614 elderly and 1104 younger patients from the ITA.LI.CA database, including 1834 HCC cases consecutively diagnosed from January 1987 to December 2004. Both groups were stratified according to treatment: hepatic resection, percutaneous procedures, transarterial chemoembolisation (TACE). Survival was assessed in the whole population and in each treatment subgroup. Age, sex, aetiology, cirrhosis, comorbidities and cancer stage (CLIP score) were tested as predictors of survival. In each subgroup, differences in patient survival were also assessed after adjustment and matching by propensity score. RESULTS: Ageing was associated with a higher prevalence of comorbidities, better liver function and CLIP score. Regardless of age, two-thirds of patients underwent radical treatments or TACE. Elderly patients underwent more ablative procedures and fewer resections or TACE sessions. The survival of elderly and younger patients was comparable in each treatment subset, and was predicted by CLIP score. This result was confirmed by the propensity analysis. CONCLUSIONS: The overall applicability of radical or effective HCC treatments was unaffected by old age. However, treatment distribution differed, elderly individuals being more frequently treated with percutaneous procedures and less frequently with resection or TACE. Survival was unaffected by age and primarily predicted by cancer stage, assessed by the CLIP system, both in the overall population and in treatment subgroups.

Is female sex a significant favorable prognostic factor in hepatocellular carcinoma?

OBJECTIVE: As sex favorably modulates the natural history of chronic liver diseases and the risk for neoplastic evolution, our study aimed to ascertain whether female hepatocellular carcinoma (HCC) patients are also characterized by better prognosis. METHODS: The ITA.LI.CA (Italian Liver Cancer) database was used, including 1834 HCC patients (482 females, 1352 males) that were consecutively diagnosed. The following variables were considered: age, etiology, modality of diagnosis, earlier interferon treatment, bilirubin, alpha-fetoprotein levels, constitutional syndrome, portal thrombosis, metastasis, number and size of nodules, grading, Child-Pugh class, tumor-nodes-metastases and Cancer of the Liver Italian Program staging, and treatment. RESULTS: Female HCC patients were characterized by older age (P=0.0001), higher prevalence of HCV infection (P=0.0001), diagnosis more frequently by surveillance (P=0.003), higher alpha-fetoprotein levels (P=0.0055), lower prevalence of constitutional syndrome (P=0.03), portal thrombosis (P=0.04), and metastasis (P=0.0001). HCC in females was more frequently unifocal (P=0.0001), smaller (P=0.001), well differentiated (P=0.001), and of lower Cancer of the Liver Italian Program and tumor-nodes-metastases stage (P=0.0001 and 0.0001). However, females underwent curative treatments (transplantation, resection, percutaneous ablation) in the same percentage of cases as males. Finally, females had a significantly longer survival (median 29 [95% confidence interval (CI): 24-33] vs. 24 (22-25) months, P=0.0001). The difference was sharper [median 36 (CI: 31-41] vs. 17 (CI: 15-19)] when females undergoing surveillance were compared with males diagnosed incidentally or for symptoms. The Cox model also identified sex as an independent predictor of survival. When only patients undergoing surveillance were considered, no significant difference was observed. CONCLUSION: HCC in females has better prognosis, but this is possibly more because of higher compliance with surveillance than to real biological differences.

Hepatocellular carcinoma in patients with cryptogenic cirrhosis.

BACKGROUND & AIMS: Patients with cryptogenic cirrhosis (CC) can develop hepatocellular carcinoma (HCC), although the clinical characteristics of HCC in these patients have not been completely defined. We aimed to characterize the clinical features of patients diagnosed with HCC after CC during a 15-year period (1992-2006). METHODS: The clinical characteristics of 45 consecutive CC patients with HCC were analyzed, along with modality of diagnosis, tumor stage, treatment, survival, and causes of death. Data were compared with those of 426 consecutive patients with HCC and only hepatitis C virus (HCV) infection, diagnosed during the same period at the Italian Liver Cancer group centers. RESULTS: HCC patients with CC had similar impairments in liver function as patients with HCV infection (Child-Pugh class A: 53% vs 65%; P = .141). However, the HCC patients with CC had lower aminotransferase levels (P < .001) and higher platelet counts (P < .001). HCC was significantly less likely to be diagnosed during surveillance in CC patients (29% vs 64%; P < .0001). Patients with CC had a significantly greater prevalence of advanced HCC stage, according to Milano criteria (69% vs 41%; P < .0005), larger HCC size (4.9 vs 3.0 cm; P = .0001), lower amenability to any treatment (27% vs 42%; P = .036), and shorter survival times (P = .009, log-rank test) compared with HCV patients. Causes of death were similar in the 2 groups. CONCLUSIONS: Compared with HCV patients, HCC in CC patients often is diagnosed at an advanced stage, probably owing to lack of surveillance; this leads to limited treatment options and shorter survival times.

Early and very early hepatocellular carcinoma: when and how much do staging and choice of treatment really matter? A multi-center study.

BACKGROUND: A consensus on the most reliable staging system for hepatocellular carcinoma (HCC) is still lacking but the most used is a revised Barcelona Clinic Liver Cancer (BCLC) system, adopted by the American Association for the Study of Liver Diseases (AASLD). We investigated how many patients are diagnosed in "very early" and "early" stage, follow the AASLD guidelines for treatment and whether their survival depends on treatment. METHODS: Data were collected in 530 "very early" and "early" HCC patients recruited by a multicentric Italian collaborative group (ITA.LI.CA). The Kaplan-Meier method was used to estimate overall survival and the log rank to test the statistical significance of difference between groups. Cox's multivariate stepwise regression analysis was used to pinpoint independent prognostic factors and the adjusted relative risks (hazard ratios) were calculated as well. A statistical analysis based on the chi-square test was used to identify significant differences in clinical or pathological features between patients. A P-value < 0.05 was considered statistically significant. RESULTS: "Very early" HCC were 3%; Cox multivariate analysis did not identify variables independently associated with survival. The patients following AASLD recommendations (20%) did not show longer survival. In "early" HCC patients (25%), treatment significantly modulated survival (p = 0.0001); the 28% patients treated according to the AASLD criteria survived longer (p = 0,004). The Cox analysis however identified only age, gender, number of lesions and Child class as independent predictors of survival. CONCLUSION: patients with very early" HCC were very few in this analysis. In most instances they were not treated with the treatment suggested as the most appropriate by the AASLD guidelines and the type of treatment had no impact on survival, even though the number of patients was relatively low and part of the patients were diagnosed before the introduction of the guidelines: this analysis, therefore, might not be considered as conclusive and should be validated. The "early" stage group involved more patients, rarely treated according to the guidelines, both overall and also in those diagnosed after their publication; the survival was in part predicted by the type of treatment, with better results in those treated according to AASLD indications.

Surveillance for early diagnosis of hepatocellular carcinoma: is it effective in intermediate/advanced cirrhosis?

OBJECTIVES: Surveillance of cirrhotic patients for early diagnosis of hepatocellular carcinoma (HCC), based on ultrasonography and alpha-fetoprotein (AFP) measurement, is widely used. Its effectiveness depends on liver function, which affects the feasibility of treatments and cirrhosis-related mortality. We assessed whether patients with intermediate/advanced cirrhosis benefit from surveillance. METHODS: We selected 468 Child-Pugh class B and 140 class C patients from the ITA.LI.CA database, including 1,834 HCC patients diagnosed from January 1987 to December 2004. HCC was detected in 252 patients during surveillance (semiannual 172, annual 80 patients; group 1) and in 356 patients outside surveillance (group 2). Survival of surveyed patients was corrected for the estimated lead time. RESULTS: Child-Pugh class B: cancer stage (P < 0.001) and treatment distribution (P < 0.001) were better in group 1 than in group 2. The median (95% CI) survivals were 17.1 (13.5-20.6) versus 12.0 (9.4-14.6) months and the survival rates at 1, 3, and 5 yr were 60.4%versus 49.2%, 26.1%versus 16.1%, and 10.7%versus 4.3%, respectively (P= 0.022). AFP, gross pathology, and treatment of HCC were independent prognostic factors. Child-Pugh class C: cancer stage (P= 0.001) and treatment distribution (P= 0.021) were better in group 1 than in group 2. Nonetheless, median survival did not differ: 7.1 (2.1-12.1) versus 6.0 (4.1-7.9) months (P= 0.740). CONCLUSIONS: These results suggest surveillance be offered to class B patients and maintained for class A patients who migrate to the subsequent class. Surveillance becomes pointless in class C patients probably because the poor liver function adversely affects the overall mortality and HCC treatments.

Impact of etiology of cirrhosis on the survival of patients diagnosed with hepatocellular carcinoma during surveillance.

OBJECTIVES: Although the etiology of liver disease affects the features of hepatocellular carcinoma (HCC) diagnosed during surveillance, it is not known whether it influences patients' survival. We analyzed the impact of etiology on the characteristics and outcome of HCC detected during surveillance. METHODS: In this cohort study, 742 patients with HCC detected during semiannual or annual surveillance were selected from the ITA.LI.CA database, including 1,834 consecutive patients observed in three primary and seven tertiary care settings for HCC. Patients were grouped according to etiology: hepatitis B virus (HBV, 87), hepatitis C virus (HCV, 461), alcohol (59), and multietiology (135). RESULTS: In all etiologic groups, most HCCs were unifocal (51-68%) and most of them were

Prevalence and prognostic significance of the presence of esophageal varices in patients with hepatocellular carcinoma.

BACKGROUND & AIMS: It has been suggested that clinically relevant portal hypertension may affect the therapeutic management and prognosis of cirrhotic patients with hepatocellular carcinoma (HCC). Nevertheless, the importance of the presence of esophageal varices in these patients has not yet been addressed formally. In this study our aim was to evaluate the prevalence and prognostic relevance of the presence of esophageal varices in a large series of patients with HCC. METHODS: The prevalence of esophageal varices was evaluated in 1153 HCC patients who were consecutively referred to 10 Italian centers (the Italian Liver Cancer group). Survival was calculated from the time of HCC diagnosis until death or until the most recent follow-up visit, and was evaluated according to the presence or absence of esophageal varices. The independent prognostic meaning of the presence of esophageal varices was evaluated further in a multivariate regression analysis. RESULTS: Esophageal varices were found in 730 patients (63.3%). Patients with varices showed significantly shorter survival times (P < .0001) as compared with patients without varices. Death as a result of bleeding was more common in patients with varices (P = .0127). In multivariate analysis, the presence of esophageal varices was associated independently with poorer survival (adjusted relative risk, 1.25; 95% confidence interval, 1.06-1.48; P = .0095). CONCLUSIONS: More than half of the patients with HCC have esophageal varices. The presence of esophageal varices is associated with a higher risk of death from bleeding, and is an independent determinant of the patient's prognosis. This variable should be taken into account in the diagnostic and therapeutic work-up of HCC patients.

Diagnostic and prognostic role of alpha-fetoprotein in hepatocellular carcinoma: both or neither?

BACKGROUND: The clinical usefulness of alpha-fetoprotein (AFP) in hepatocellular carcinoma (HCC) management is debatable. OBJECTIVES: To assess, in a large multi-centric survey, diagnostic and prognostic reliability of AFP, predictive factors, and any correlation with the tumor immunophenotype. METHODS: A total of 1,158 patients with HCC were analyzed with reference to serum AFP levels at diagnosis. We evaluated: HCC grading, histotype, and size; Okuda, tumor-nodes-metastases (TNM), and Child-Pugh scores; liver function, symptoms, presence of metastases or portal thrombosis, etiology, survival, and treatment. In 66 patients with histological diagnosis, the pathologists evaluated p53 overexpression, MIB 1 labeling index, BCL-2 positive cells (index of apoptosis), and CD44 (adhesion molecule) positivity. RESULTS: Patients were divided into three AFP groups: normal (<20 ng/mL) [46%], elevated (21-400 ng/mL) [36%], and diagnostic (>400 ng/mL) [18%]. Statistical correlations were significant for: weight loss (p= 0.0056), pain (p= 0.0025), Child-Pugh score (p= 0.001), tumor size, Okuda's and TNM stages, metastases, thrombosis, type of treatment (all p < 0.0001), and female sex (p < 0.004). AFP correlated with survival overall, in patients untreated, transplanted, or undergoing locoregional treatments; but not in those surgically treated. In the discriminant analysis, the related variables were size, female sex, Child-Pugh score, TNM staging (steps 1-4). When using the receiver operating characteristic curve, the prognostic reliability of AFP was limited with area under the curve of 0.59. Finally, patients with low expression of BCL2 had high AFP levels (p < 0.05). AFP positively correlated with Edmonson score (p < 0.0001). CONCLUSION: The evaluation of this large series of HCC patients allowed us to: confirm the low sensitivity (54%) of AFP in the diagnosis of HCC and its prognostic value, albeit limited, being tumor size, female sex (intriguingly enough), Child-Pugh score, and TNM staging independent predictors.

Effect of the etiology of viral cirrhosis on the survival of patients with hepatocellular carcinoma.

OBJECTIVES: The aim of this study was to assess whether hepatocellular carcinoma occurring in the setting of hepatitis B or C virus infection has different prognosis. METHODS: We performed a multicentric case-control study comparing 102 pairs of patients affected by hepatitis B virus- or hepatitis C virus-related hepatocellular carcinoma. Patients were matched for sex (male/female: 84/18 pairs), age, center, and period of enrollment, underlying chronic liver disease (cirrhosis/chronic hepatitis: 97/5 pairs), Child-Pugh class (A/B/C: 70/25/7 pairs), hepatocellular carcinoma stage (nonadvanced/advanced: 50/52 pairs) and, when possible, modality of cancer diagnosis (75 pairs: 47 during and 28 outside surveillance). RESULTS: In the whole population, patients with hepatitis B tended to have a poor prognosis than those with hepatitis C (p = 0.160), and this difference became statistically significant among the patients with an advanced hepatocellular carcinoma (p = 0.025). Etiology, Child-Pugh class, gross pathology, and alpha-fetoprotein were the significant independent prognostic factors in the whole population. The distribution of these prognostic factors did not differ between patients with hepatitis B or hepatitis C, both in the whole population and in the subgroup of advanced hepatocellular carcinomas. CONCLUSION: Hepatitis B virus-related hepatocellular carcinomas have a greater aggressiveness than hepatitis C virus-related tumors, which becomes clinically manifest once they have reached an advanced stage.

Surveillance for hepatocellular carcinoma in elderly Italian patients with cirrhosis: effects on cancer staging and patient survival.

OBJECTIVES: Surveillance of cirrhotic individuals for early detection of HCC, based on ultrasonography (US) and alpha1-fetoprotein (AFP) determination, is a recommended practice currently applied also to elderly patients. However, several age-related factors may jeopardize the results of surveillance in these patients. Aim of the study was to evaluate the benefit of surveillance for HCC in elderly individuals. METHODS: Multicenter retrospective study on 1,277 consecutive patients with HCC. The inclusion criteria were: underlying chronic liver disease, description of cancer stage, and modalities of its diagnosis. Among the 1,037 patients fulfilling these criteria, 363 aged > or = 70 yr were considered. RESULTS: The tumor was detected during surveillance, based on US and AFP performed every 6-12 months, in 158 individuals (group 1), incidentally in 138 (group 2) and because of symptoms in 67 (group 3). Surveillance reduced the risk of dealing with an advanced cancer (odds ratio (95% Confidence Interval): 0.18 (0.09-0.37) vs group 3, and 0.29 (0.17-0.49) vs group 2). The frequency of effective treatments decreased from group 1 to group 3 (73%, 57%, and 31%, respectively). The main cause of death was HCC progression. The survival corrected for the lead time of group 1 (median: 24 months) was significantly better than the crude survival of group 3 (7 months; p= 0.003) and barely better than that of group 2 (21 months). The latter also showed a better prognosis with respect to group 3 (p= 0.018). CONCLUSIONS: Surveillance for HCC improves the survival of elderly cirrhotic patients by expanding the percentage of cancers amenable to effective treatments.
