Diagnostic and Prognostic Role of alpha-Fetoprotein in Hepatocellular Carcinoma: Both or Neither?
The clinical usefulness of alpha-fetoprotein (AFP) in hepatocellular carcinoma (HCC) management is debatable. To assess, in a large multi-centric survey, diagnostic and prognostic reliability of AFP, predictive factors, and any correlation with the tumor immunophenotype. 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. 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). 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.
Barcelona Clinic Liver Cancer staging and transplant survival benefit for patients with hepatocellular carcinoma: a multicentre, cohort study
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. 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. 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. 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. None.
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.
Development and Validation of a New Prognostic System for Patients with Hepatocellular Carcinoma
Prognostic assessment in patients with hepatocellular carcinoma (HCC) remains controversial. Using the Italian Liver Cancer (ITA.LI.CA) database as a training set, we sought to develop and validate a new prognostic system for patients with HCC. Prospective collected databases from Italy (training cohort, n = 3,628; internal validation cohort, n = 1,555) and Taiwan (external validation cohort, n = 2,651) were used to develop the ITA.LI.CA prognostic system. We first defined ITA.LI.CA stages (0, A, B1, B2, B3, C) using only tumor characteristics (largest tumor diameter, number of nodules, intra- and extrahepatic macroscopic vascular invasion, extrahepatic metastases). A parametric multivariable survival model was then used to calculate the relative prognostic value of ITA.LI.CA tumor stage, Eastern Cooperative Oncology Group (ECOG) performance status, Child-Pugh score (CPS), and alpha-fetoprotein (AFP) in predicting individual survival. Based on the model results, an ITA.LI.CA integrated prognostic score (from 0 to 13 points) was constructed, and its prognostic power compared with that of other integrated systems (BCLC, HKLC, MESIAH, CLIP, JIS). Median follow-up was 58 mo for Italian patients (interquartile range, 26-106 mo) and 39 mo for Taiwanese patients (interquartile range, 12-61 mo). The ITA.LI.CA integrated prognostic score showed optimal discrimination and calibration abilities in Italian patients. Observed median survival in the training and internal validation sets was 57 and 61 mo, respectively, in quartile 1 (ITA.LI.CA score ≤ 1), 43 and 38 mo in quartile 2 (ITA.LI.CA score 2-3), 23 and 23 mo in quartile 3 (ITA.LI.CA score 4-5), and 9 and 8 mo in quartile 4 (ITA.LI.CA score > 5). Observed and predicted median survival in the training and internal validation sets largely coincided. Although observed and predicted survival estimations were significantly lower (log-rank test, p < 0.001) in Italian than in Taiwanese patients, the ITA.LI.CA score maintained very high discrimination and calibration features also in the external validation cohort. The concordance index (C index) of the ITA.LI.CA score in the internal and external validation cohorts was 0.71 and 0.78, respectively. The ITA.LI.CA score's prognostic ability was significantly better (p < 0.001) than that of BCLC stage (respective C indexes of 0.64 and 0.73), CLIP score (0.68 and 0.75), JIS stage (0.67 and 0.70), MESIAH score (0.69 and 0.77), and HKLC stage (0.68 and 0.75). The main limitations of this study are its retrospective nature and the intrinsically significant differences between the Taiwanese and Italian groups. The ITA.LI.CA prognostic system includes both a tumor staging-stratifying patients with HCC into six main stages (0, A, B1, B2, B3, and C)-and a prognostic score-integrating ITA.LI.CA tumor staging, CPS, ECOG performance status, and AFP. The ITA.LI.CA prognostic system shows a strong ability to predict individual survival in European and Asian populations.
Application of the Intermediate-Stage Subclassification to Patients With Untreated Hepatocellular Carcinoma
The Barcelona Clinic Liver Cancer (BCLC) intermediate stage (BCLC B) includes a heterogeneous population of patients with hepatocellular carcinoma (HCC). Recently, in order to facilitate treatment decisions, a panel of experts proposed to subclassify BCLC B patients. In this study, we aimed to assess the prognostic capability of the BCLC B stage reclassification in a large cohort of patients with untreated HCC managed by the Italian Liver Cancer Group. We assessed the prognosis of 269 untreated HCC patients observed in the period 1987-2012 who were reclassified according to the proposed subclassification of the BCLC B stage from stage B1 to stage B4. We evaluated and compared the survival of the various substages. Median survival progressively decreased from stage B1 (n=65, 24.2%: 25 months) through stages B2 (n=105, 39.0%: 16 months) and B3 (n=22, 8.2%: 9 months), to stage B4 (n=77, 28.6%: 5 months; P<0.0001). Moreover, we observed a significantly different survival between contiguous stages (B1 vs. B2, P=0.0002; B2 vs. B3, P<0.0001; B3 vs. B4, P=0.0219). In multivariate analysis, the BCLC B subclassification (P<0.0001), MELD score (P=0.0013), and platelet count (P=0.0252) were independent predictors of survival. The subclassification of the intermediate-stage HCC predicts the prognosis of patients with untreated HCC. The prognostic figures identified in this study may be used as a benchmark to assess the efficacy of therapeutic intervention in the various BCLC B substages, whereas it remains to be established whether incorporation of the MELD score might improve the prognosis of treated patients.
Treatments for hepatocellular carcinoma in elderly patients are as effective as in younger patients: a 20-year multicentre experience
ObjectivesThe number of elderly patients diagnosed with hepatocellular carcinoma (HCC) is expected to increase. We compared the presenting features and outcome of HCC in elderly (≥70 years) and younger patients (<70 years).DesignMulticentre retrospective cohort study and nested case–control study.Patients614 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.ResultsAgeing 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.ConclusionsThe 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.
Utility of Tumor Burden Score to Stratify Prognosis of Patients with Hepatocellular Cancer: Results of 4759 Cases from ITA.LI.CA Study Group
Background Dichotomous models like Milan Criteria represent the routinely used tools for predicting the outcome of patients with hepatocellular carcinoma (HCC). However, a paradigm shift from a dichotomous to continuous prognostic stratification should represent a good strategy for improving the prediction process. Recently, the tumor burden score (TBS) has been proposed for selecting patients with colorectal liver metastases. To date, TBS has not been validated in a large HCC population. The main objective of this study was to evaluate the prognostic power of TBS in an HCC population treated with different curative and palliative modalities. Methods Prospectively collected data from consecutive HCC patients managed in 24 institutions participating in the ITA.LI.CA group between Jan 2002 and Mar 2015 were analyzed ( n  = 4759). A sub-analysis focused on 3909 patients with the radiological evidence of vascular invasion or metastatic disease was also performed. Results TBS demonstrated the best discriminative ability when compared to MC and other tumor-specific scores. At multivariable Cox regression analysis, TBS was an independent risk factor of overall survival, with a 6% increased risk for patient death for each point increase in TBS. At survival analysis, when TBS ≥ 8 was connected with MELD ≥ 15 and alpha-fetoprotein ≥ 1000 ng/mL, patients presenting all these three risk factors presented the worst results ( p value < 0.0001). Conclusions Survival prediction of HCC patients was very well done using TBS model, even stratifying the population in relation to the presence of metastases and/or vascular invasion. TBS model was the best in terms of discriminatory ability and goodness of fit when compared with other continuous or binary variables. Its incorporation in a model composed by tumor- and liver function-related variables further increases its survival prediction.
Surveillance for Early Diagnosis of Hepatocellular Carcinoma: Is It Effective in Intermediate/Advanced Cirrhosis?
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. 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. 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). 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.

Surveillance for Hepatocellular Carcinoma in Elderly Italian Patients With Cirrhosis: Effects on Cancer Staging and Patient Survival
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. 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. 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). Surveillance for HCC improves the survival of elderly cirrhotic patients by expanding the percentage of cancers amenable to effective treatments.
