Sorafenib and Metronomic Capecitabine in Child-Pugh B patients with advanced HCC: A real-life comparison with best supportive care.

BACKGROUND AND AIMS: The efficacy of systemic therapy for unresectable advanced hepatocellular carcinoma (aHCC) has not been proven in patients with Child-Pugh (C-P) B cirrhosis. Nevertheless, in real-world these patients are treated both with tyrosine kinase inhibitors (TKIs) and with metronomic capecitabine (MC). This study aimed to compare sorafenib and MC outcomes versus best supportive care (BSC) in C-P B patients. METHOD: Between 2008 and 2020, among 774 C-P B patients with aHCC not amenable/responsive to locoregional treatments, 410 underwent sorafenib, 62 MC, and 302 BSC. The propensity score matching method was used to correct the baseline unbalanced prognostic factors. RESULTS: In the unmatched population, median OS was 9.7 months in patients treated with sorafenib, 8.0 with MC, and 3.9 months with BSC. In sorafenib vs. BSC-matched patients (135 couples), median OS was 7.3 (4.9-9.6) vs. 3.9 (2.6-5.2) months (p<0.001). ECOG-Performance Status, tumor size, macrovascular invasion, AFP, treatment-naive, and sorafenib were independent predictors of survival. In MC vs. BSC-matched patients (40 couples), median OS was 9.0 (0.2-17.8) vs.3.0 (2.2-3.8) months (p<0.001). Median OS did not differ (p = 0.283) in sorafenib vs. MC-matched patients (55 couples). CONCLUSION: C-P B patients with aHCC undergoing BSC have poor survival. Both Sorafenib and MC treatment improve their prognosis.

Landscape of alcohol-related hepatocellular carcinoma in the last 15 years highlights the need to expand surveillance programs.

Background & Aims: Alcohol abuse and metabolic disorders are leading causes of hepatocellular carcinoma (HCC) worldwide. Alcohol-related aetiology is associated with a worse prognosis compared with viral agents, because of the lower percentage of patients diagnosed with HCC under routine surveillance and a higher burden of comorbidity in alcohol abusers. This study aimed to describe the evolving clinical scenario of alcohol-related HCC over 15 years (2006-2020) in Italy. Methods: Data from the Italian Liver Cancer (ITA.LI.CA) registry were used: 1,391 patients were allocated to three groups based on the year of HCC diagnosis (2006-2010; 2011-2015; 2016-2020). Patient characteristics, HCC treatment, and overall survival were compared among groups. Survival predictors were also investigated. Results: Approximately 80% of alcohol-related HCCs were classified as cases of metabolic dysfunction-associated fatty liver disease. Throughout the quinquennia, <50% of HCCs were detected by surveillance programmes. The tumour burden at diagnosis was slightly reduced but not enough to change the distribution of the ITA.LI.CA cancer stages. Intra-arterial and targeted systemic therapies increased across quinquennia. A modest improvement in survival was observed in the last quinquennia, particularly after 12 months of patient observation. Cancer stage, HCC treatment, and presence of oesophageal varices were independent predictors of survival. Conclusions: In the past 15 years, modest improvements have been obtained in outcomes of alcohol-related HCC, attributed mainly to underuse of surveillance programmes and the consequent low amenability to curative treatments. Metabolic dysfunction-associated fatty liver disease is a widespread condition in alcohol abusers, but its presence did not show a pivotal prognostic role once HCC had developed. Instead, the presence of oesophageal varices, an independent poor prognosticator, should be considered in patient management and refining of prognostic systems. Impact and Implications: Alcohol abuse is a leading and growing cause of hepatocellular carcinoma (HCC) worldwide and is associated with a worse prognosis compared with other aetiologies. We assessed the evolutionary landscape of alcohol-related HCC over 15 years in Italy. A high cumulative prevalence (78%) of metabolic dysfunction-associated fatty liver disease, with signs of metabolic dysfunction, was observed in HCC patients with unhealthy excessive alcohol consumption. The alcohol + metabolic dysfunction-associated fatty liver disease condition tended to progressively increase over time. A modest improvement in survival occurred over the study period, likely because of the persistent underuse of surveillance programmes and, consequently, the lack of improvement in the cancer stage at diagnosis and the patients' eligibility for curative treatments. Alongside the known prognostic factors for HCC (cancer stage and treatment), the presence of oesophageal varices was an independent predictor of poor survival, suggesting that this clinical feature should be carefully considered in patient management and should be included in prognostic systems/scores for HCC to improve their performance.

Potential feasibility of atezolizumab-bevacizumab therapy in patients with hepatocellular carcinoma treated with tyrosine-kinase inhibitors.

BACKGROUND: The combination of atezolizumab-bevacizumab has been proven to be superior to sorafenib for the treatment of unresectable hepatocellular carcinoma not amenable to locoregional treatments, becoming the standard of care of systemic therapy. AIM: This study aimed at assessing real-world feasibility of atezolizumab-bevacizumab in patients treated with tyrosine-kinase inhibitors. METHODS: Among 1447 patients treated with tyrosine-kinase inhibitors from January 2010 to December 2020, we assessed the percentage of those potentially eligible to atezolizumab-bevacizumab (according to IMbrave-150 trial criteria), and the overall survival of eligible and non-eligible patients. RESULTS: 422 (29%) patients were qualified for atezolizumab-bevacizumab therapy. The main exclusion causes were Child-Pugh class and Performance Status. Adopting the more permissive inclusion criteria of SHARP trial, 535 patients became eligible. The median overall survival of tyrosine-kinase inhibitors patients was 14.9 months, longer in eligible patients than in their counterpart due to better baseline liver function and oncological features. CONCLUSION: Real-world data indicate that less than one-third of hepatocellular carcinoma patients treated with tyrosine-kinase inhibitors are potentially eligible to atezolizumab-bevacizumab according to the registration trial criteria. These patients have a longer survival than the non-eligible ones. If the selection criteria of atezolizumab-bevacizumab trial are maintained in clinical practice, tyrosine-kinase inhibitors will remain the most used systemic therapy for hepatocellular carcinoma patients.

QT interval prolongation by acute gastrointestinal bleeding in patients with cirrhosis.

BACKGROUND & AIMS: QT interval prolongation is frequent in cirrhosis, and stressful conditions could further prolong QT. We aimed to test this hypothesis and, if it proved correct, to assess its prognostic meaning. METHODS: We reviewed the clinical records of 70 consecutive cirrhotic and 40 non-cirrhotic patients with acute gastrointestinal bleeding. All patients had been evaluated before bleeding (T0) and were re-evaluated at the time of bleeding (T1) and 6 weeks afterwards (T2). RESULTS: QT corrected by heart rate (QTc) lengthened at T1, returning towards baseline values at T2 (mean ± SEM; from 415.9 ± 4.3 to 453.4 ± 4.3 to 422.2 ± 5.7 ms, P < 0.001) in cirrhotics; contrariwise, QTc did not change in non-cirrhotic patients. The 6-week mortality was 29.6% among cirrhotic patients, while no control patient died. At T1, patients who died had longer QTc (P = 0.001) and higher model of end-stage liver disease (MELD) score (P < 0.001) than survivors. MELD and QTc independently predicted survival. Their areas under the ROC curve were 0.88 (CI 95% 0.78-0.95) and 0.75 (CI 95% 0.63-0.85) respectively; the best cut-off values were MELD ≥20 and QTc ≥ 460 ms. Based on these factors, the 6-week mortality was: 0% for patients without risk factors, 32.1% for those with one risk factor and 70.6% for those with both (P < 0.001). CONCLUSIONS: Acute gastrointestinal bleeding further prolongs QTc in cirrhosis. This abnormality independently predicts bleeding-induced mortality. The combined measurement of QTc interval and MELD can clearly identify three patient strata at increasing risk of bleeding-related mortality, thus improving the decision-making for these patients.

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.

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.

Hepatocellular carcinoma in non-cirrhotic liver: a reappraisal.

Although not frequently, hepatocellular carcinoma (HCC) can ensue in a non-cirrhotic liver. As compared to cirrhotic HCC, this kind of tumour has some peculiarities, such as: (a) a lower male preponderance and a bimodal age distribution; (b) a lower prevalence of the three main risk factors (hepatitis B and C virus infections and alcohol abuse), with an increased prevalence of other etiologic factors, such as exposure to genotoxic substances and sex hormones, inherited diseases, genetic mutations; (c) a more advanced tumour stage at the time of diagnosis, as it is usually detected due to the occurrence of cancer-related symptoms, outside any scheduled surveillance program; (d) a much higher amenability to hepatic resection, due to the low risk of liver failure even after extended parenchymal mutilation; (e) overall and disease-free survivals after resection of non-advanced tumours (meeting the Milano criteria) comparable to that obtained with liver transplantation in cirrhotic patients carrying an early tumour; (f) overall survival strictly dependent on tumour burden (and its recurrence) and barely influenced by liver function.

Telangiectasia as a presenting sign of Graves' disease.

Acquired nevoid telangiectasia (ANT) is observed in several conditions including primary cutaneous disorders, systemic autoimmune disease and hyperestrogenism occurring in puberty, pregnancy and chronic liver disease. We describe a patient in whom ANT was a presenting sign of autoimmune hyperthyroidism, which improved after thyroidectomy. A 43-year-old Caucasian woman experienced an asymptomatic development of multiple widespread red skin lesions, diagnosed to be ANT. Blood tests revealed increased serum levels of free tri-iodothyronine and thyroxine and suppressed thyroid-stimulating hormone. Other causes of ANT were excluded. ANT improved but did not disappear after thyroidectomy. The possible pathogenetic factors linking ANT and Graves' disease, such as an immune-mediated process, altered estrogen metabolism or vasodilatation associated with hyperdynamic circulation, are discussed.

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.

Hepatocellular carcinoma: trends of incidence and survival in Europe and the United States at the end of the 20th century.

OBJECTIVES: There is large geographic variation in incidence levels and time trends of hepatocellular carcinoma. We compared population-based liver cancer incidence and survival in European and U.S. populations in order to elucidate geographic differences and time trends for these variables. METHODS: Since comparisons based on cancer registry data are problematic because of variations in liver cancer definition and coding, we considered a subset of cases likely to be mainly hepatocellular carcinoma, suitable for international comparison. Incidence and 5-yr relative survival were calculated from cases diagnosed in five European regions (30,423 cases) and the United States (6,976 cases) in 1982-1994. RESULTS: Age-standardized incidence was highest in southern Europe (12/100,000 in men and 3/100,000 in women in 1992-94) and lowest in northern Europe, where incidence was similar to that of the United States (3/100,000 in men, <1/100,000 in women). Over the study period, incidence remained stable in the United States and most of Europe, except for a notable increase in southern Europe. Five-year relative survival was <10% in Europe, ranging from 8% (southern Europe) to 5% (eastern Europe), and 6% in the United States. Survival increased slightly with time, mainly in southern Europe and was unaffected by sex, but was better in younger patients. CONCLUSIONS: Increasing incidence in southern Europe is probably related to hepatitis B and C infection and increasing alcohol intake, while improving survival may be due to greater surveillance for cirrhosis. The survival gap between clinical and population-based series suggests management is better in centers of excellence.

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
