Spontaneously ruptured hepatocellular carcinoma on non-cirrhotic liver: A prospective case series.

BACKGROUND AND AIMS: Spontaneous ruptured hepatocellular carcinoma is an uncommon complication, and there are scarce data about non-cirrhotic patients. Tumor treatment is not standardized and the risk of peritoneal dissemination is unclear. AIM: we analyzed the treatment and survival in patients with rHCC on non-cirrhotic liver. METHODS: One hundred and forty-one non-cirrhotic patients with hepatocellular carcinoma diagnosed by histology were included in a multicenter prospective registry (2018-2022). Seven of them (5%) presented with hemoperitoneum due to spontaneous rupture. RESULTS: Liver disease was associated in three patients (42.9%). A single nodule was detected in three cases (42.9%). One patient had vascular invasion and none extrahepatic spread. Initial hemostatic therapy and sequential treatment was individualized. Patients with single nodule were treated: resection (one case) with recurrence at 4 months treated with TACE and sorafenib. TACE/TAE followed by surgery (two cases) one in remission 43 months later, the other had liver recurrence at 18 months and was transplanted. Patients with multiple lesions were treated: TAE/emergency surgery and subsequent systemic therapy (two cases), one received lenvatinib (1-year survival) and the other sorafenib (5-month survival). TAE and surgery with subsequent systemic therapy (one case). Initial hemostatic surgery, dying on admission (one case). No patient developed intraperitoneal metastasis. All patients with multiple lesions died by tumor. The 3-year survival rate was 42.9%. CONCLUSIONS: Initial hemostasis was achieved in all patients by TAE/TACE or surgery. Subsequent treatment was individualized, based on tumor characteristics, regardless of rupture. Long-time remission could be achieved in single nodule patients.

High frequency of acute decompensation and cancer in patients with compensated cirrhosis due to nonalcoholic fatty liver disease: A retrospective cohort study.

The natural history of compensated cirrhosis due to nonalcoholic fatty liver disease (NAFLD) has not been completely characterized. The aim of the present study was to assess the incidence and risk factors of acute decompensation of cirrhosis, hepatocellular carcinoma, and extrahepatic cancers. This was a multicenter, retrospective, cohort study including 449 patients with compensated cirrhosis due to NAFLD. We calculated cumulative incidences and used competitive risk analysis to determine the risk factors associated with decompensation and cancer development. Over a median of 39 months of follow-up, 124 patients (28%) presented acute decompensation. The most frequent decompensation was ascites (21%) followed by hepatic encephalopathy (15%), variceal bleeding (9%), and spontaneous bacterial peritonitis (3%). Acute-on-chronic liver failure was diagnosed in 6% of patients during follow-up. Liver function parameters and specifically an albumin level below 40 g/L were independently associated with an increased risk of decompensation. The presence of ischemic heart disease was independently associated with acute decompensation. Seventy-eight patients (18%) developed hepatocellular carcinoma or extrahepatic cancers during follow-up (51 and 27, respectively). Conclusion: Patients with compensated cirrhosis due to NAFLD are at high risk of severe liver complications, such as the development of acute decompensation, in a relative short follow-up time. This population is at high risk of hepatic and extrahepatic cancers.

Survival of patients with cirrhosis and acute peptic ulcer bleeding compared with variceal bleeding using current first-line therapies.

The presence of cirrhosis increases the mortality of patients with peptic ulcer bleeding (PUB). Both acute variceal bleeding (AVB) and PUB are associated with substantial mortality in cirrhosis. This multicenter cohort study was performed to assess whether the mortality of patients with cirrhosis with PUB is different from that of those with AVB. Patients with cirrhosis and acute gastrointestinal bleeding were consecutively included and treated with somatostatin and proton pump inhibitor infusion from admission and with antibiotic prophylaxis. Emergency endoscopy with endoscopic therapy was performed within the first 6 hours. 646 patients with AVB and 144 with PUB were included. There were baseline differences between groups, such as use of gastroerosive drugs or ß-blockers. Child-Pugh and Model for End-Stage Liver Disease MELD scores were similar. Further bleeding was more frequent in the AVB group than those in the PUB group (18% vs. 10%; odds ratio [OR] = 0.50; 95% confidence interval [CI] = 0.29-0.88). However, mortality risk at 45 days was similar in both groups (19% in the AVB group vs. 17% in the PUB group; OR = 0.85; 95% CI = 0.55-1.33; P = 0.48). Different parameters, such as Child-Pugh score, acute kidney injury, acute on chronic liver failure, or presence of shock or bacterial infection, but not the cause of bleeding, were related to the risk of death. Only 2% of the PUB group versus 3% of the AVB group died with uncontrolled bleeding (P = 0.39), whereas the majority of patients in either group died from liver failure or attributed to other comorbidities. CONCLUSION: Using current first-line therapy, patients with cirrhosis and acute peptic ulcer bleeding have a similar survival than those with variceal bleeding. The risk of further bleeding is higher in patients with variceal hemorrhage. However, few patients in both groups died from uncontrolled bleeding, rather the cause of death was usually related to liver failure or comorbidities. (Hepatology 2018;67:1458-1471).

Clinical characteristics of hepatocellular carcinoma in Spain. Comparison with the 2008-2009 period and analysis of the causes of diagnosis out of screening programs. Analysis of 686 cases in 73 centers. / Características clínicas del carcinoma hepatocelular en España. Comparación con el período 2008-2009 y análisis de las causas del diagnóstico fuera de cribado. Estudio de 686 casos en 73 centros.

BACKGROUND AND OBJECTIVE: In 2010 we published that 53% of cases of hepatocellular carcinoma (HCC) detected in Spain were diagnosed outside the context of standard screening programs, which consequently leads to lower survival rates. The aim of this study was to analyze the current situation and the causes of diagnosis out of screening programs. MATERIAL AND METHODS: Prospective registry of 73 second- and third-level Spanish healthcare centers carried out between October 1, 2014 and January 31, 2015. The baseline characteristics of the disease and the first treatment administered for the incidental primary liver tumors during such period were recorded. RESULTS: A total of 720 patients were included in the study: HCC (n=686), intrahepatic cholangiocarcinoma (n=29), hepatic cholangiocarcinoma (n=2), other (n=3). HCC characteristics: male 82%; mean age 67 years; cirrhosis 87%; main etiologies: alcohol 35%, HCV 30%, alcohol and HCV 15%, non-alcoholic fatty liver disease 6%; tumor stage: BCLC-0 11%, A 43%, B 19%, C 16% and D 11%; first treatment: transarterial chemoembolization (23%), percutaneous ablation (22%), symptomatic treatment (20%), resection (11%), sorafenib (11%). Three hundred and fifty-six patients (53%) were diagnosed outside of screening programs, mainly owing to the fact that they suffered from an undiagnosed liver disease (76%) and to the poor adherence to the screening program (18%). These patients were mainly male (P<.001), with an alcoholic etiology (P<.001) and active alcohol consumption (P<.001). Moreover, the disease was predominantly diagnosed at more advanced stages (P<.001) and was addressed with less radical treatments (P<.001). CONCLUSIONS: In Spain, the main cause of diagnosis of a HCC outside the context of a screening program is the absence of a prior diagnosis of a liver disease, particularly in alcohol-consuming men. Detecting a liver disease in asymptomatic populations and improving adherence to screening programs are the main areas that must be subject to improvement in order to improve the early detection of HCC.

A randomized trial to assess whether portal pressure guided therapy to prevent variceal rebleeding improves survival in cirrhosis.

Monitoring the hemodynamic response of portal pressure (PP) to drug therapy accurately stratifies the risk of variceal rebleeding (VRB). We assessed whether guiding therapy with hepatic venous pressure gradient (HVPG) monitoring may improve survival by preventing VRB. Patients with cirrhosis with controlled variceal bleeding were randomized to an HVPG-guided therapy group (N = 84) or to a control group (N = 86). In both groups, HVPG and acute ß-blocker response were evaluated at baseline and HVPG measurements were repeated at 2-4 weeks to determine chronic response. In the HVPG-guided group, acute responders were treated with nadolol and acute nonresponders with nadolol+nitrates. Chronic nonresponders received nadolol+prazosin and had a third HVPG study. Ligation sessions were repeated until response was achieved. The control group was treated with nadolol+nitrates+ligation. Between-group baseline characteristics were similar. During long-term follow-up (median of 24 months), mortality was lower in the HVPG-guided therapy group than in the control group (29% vs. 43%; hazard ratio [HR] = 0.59; 95% confidence interval [CI] = 0.35-0.99). Rebleeding occurred in 19% versus 31% of patients, respectively (HR = 0.53; 95% CI = 0.29-0.98), and further decompensation of cirrhosis occurred in 52% versus 72% (HR = 0.68; 95% CI = 0.46-0.99). The survival probability was higher with HVPG-guided therapy than in controls, both in acute (HR = 0.59; 95% CI = 0.32-1.08) and chronic nonresponders (HR = 0.48; 95% CI = 0.23-0.99). HVPG-guided patients had a greater reduction of HVPG and a lower final value than controls (P < 0.05). CONCLUSION: HVPG monitoring, by stratifying risk and targeting therapy, improves the survival achieved with currently recommended treatment to prevent VRB using ß-blockers and ligation. HVPG-guided therapy achieved a greater reduction in PP, which may have contributed to reduce the risk of rebleeding and of further decompensation of cirrhosis, thus contributing to a better survival.

Drugs plus ligation to prevent rebleeding in cirrhosis: an updated systematic review.

BACKGROUND & AIMS: Combined therapy with endoscopic variceal ligation (EVL) and ß-blockers ± isosorbide mononitrate (ISMN) is currently recommended to prevent variceal rebleeding. However, the role of this combined therapy has been challenged by some studies. We performed a systematic review to assess the value of combined therapy with EVL and ß-blockers ± ISMN as compared with each treatment alone to prevent rebleeding. METHODS: Databases, references and meeting abstracts were searched to retrieve randomized trials comparing combined therapy with EVL and ß-blockers ± ISMN vs either treatment alone, to prevent variceal rebleeding in cirrhosis. Random-effects model was used for meta-analysis. RESULTS: We identified five studies comparing EVL alone or combined with drugs, including a total of 476 patients. Combination therapy reduced overall rebleeding [risk ratios (RR) = 0.44, 95% confidence interval (CI) = 0.28-0.69], and showed a trend towards lower mortality (RR = 0.58, 95% CI = 0.33-1.03), without increasing complications. We identified four trials comparing drugs alone or associated with EVL, including 409 patients. All used ß-blockers plus ISMN. Variceal rebleeding decreased with combined therapy (P < 0.01) but rebleeding from oesophageal ulcers increased (P = 0.01). Overall, there was a trend towards lower rebleeding (RR = 0.76, 95% CI = 0.58-1.00) without effect on mortality (RR = 1.24, 95% CI = 0.90-1.70). CONCLUSIONS: The addition of drug therapy to EVL improves the efficacy of EVL alone. However, the addition of EVL to ß-blockers and ISMN achieves a non-significant decrease of rebleeding with no effect on mortality. Although combination therapy with EVL plus ß-blockers ± ISMN is adequate to prevent rebleeding, ß-blockers + ISMN alone may be a valid alternative.

Rebleeding prophylaxis improves outcomes in patients with hepatocellular carcinoma. A multicenter case-control study.

UNLABELLED: Outcome of variceal bleeding (VB) in patients with hepatocellular carcinoma (HCC) is unknown. We compared outcomes after VB in patients with and without HCC. All patients with HCC and esophageal VB admitted between 2007 and 2010 were included. Follow-up was prolonged until death, transplantation, or June 2011. For each patient with HCC, a patient without HCC matched by age and Child-Pugh class was selected. A total of 292 patients were included, 146 with HCC (Barcelona Classification of Liver Cancer class 0-3 patients, A [in 25], B [in 29], C [in 45], and D [in 41]) and 146 without HCC. No differences were observed regarding previous use of prophylaxis, clinical presentation, endoscopic findings, and initial endoscopic treatment. Five-day failure was similar (25% in HCC versus 18% in non-HCC; P = 0.257). HCC patients had greater 6-week rebleeding rate (16 versus 7%, respectively; P = 0.025) and 6-week mortality (30% versus 15%; P = 0.003). Fewer patients with HCC received secondary prophylaxis after bleeding (77% versus 89%; P = 0.009), and standard combination therapy was used less frequently (58% versus 70%; P = 0.079). Secondary prophylaxis failure was more frequent (50% versus 31%; P = 0.001) and survival significantly shorter in patients with HCC (median survival: 5 months versus greater than 38 months in patients without HCC; P < 0.001). Lack of prophylaxis increased rebleeding and mortality. On multivariate analysis Child-Pugh score, presence of HCC, portal vein thrombosis, and lack of secondary prophylaxis were predictors of death. CONCLUSIONS: Patients with HCC and VB have worse prognosis than patients with VB without HCC. Secondary prophylaxis offers survival benefit in HCC patients.

Transfusion strategies for acute upper gastrointestinal bleeding.

BACKGROUND: The hemoglobin threshold for transfusion of red cells in patients with acute gastrointestinal bleeding is controversial. We compared the efficacy and safety of a restrictive transfusion strategy with those of a liberal transfusion strategy. METHODS: We enrolled 921 patients with severe acute upper gastrointestinal bleeding and randomly assigned 461 of them to a restrictive strategy (transfusion when the hemoglobin level fell below 7 g per deciliter) and 460 to a liberal strategy (transfusion when the hemoglobin fell below 9 g per deciliter). Randomization was stratified according to the presence or absence of liver cirrhosis. RESULTS: A total of 225 patients assigned to the restrictive strategy (51%), as compared with 61 assigned to the liberal strategy (14%), did not receive transfusions (P<0.001) [corrected].The probability of survival at 6 weeks was higher in the restrictive-strategy group than in the liberal-strategy group (95% vs. 91%; hazard ratio for death with restrictive strategy, 0.55; 95% confidence interval [CI], 0.33 to 0.92; P=0.02). Further bleeding occurred in 10% of the patients in the restrictive-strategy group as compared with 16% of the patients in the liberal-strategy group (P=0.01), and adverse events occurred in 40% as compared with 48% (P=0.02). The probability of survival was slightly higher with the restrictive strategy than with the liberal strategy in the subgroup of patients who had bleeding associated with a peptic ulcer (hazard ratio, 0.70; 95% CI, 0.26 to 1.25) and was significantly higher in the subgroup of patients with cirrhosis and Child-Pugh class A or B disease (hazard ratio, 0.30; 95% CI, 0.11 to 0.85), but not in those with cirrhosis and Child-Pugh class C disease (hazard ratio, 1.04; 95% CI, 0.45 to 2.37). Within the first 5 days, the portal-pressure gradient increased significantly in patients assigned to the liberal strategy (P=0.03) but not in those assigned to the restrictive strategy. CONCLUSIONS: As compared with a liberal transfusion strategy, a restrictive strategy significantly improved outcomes in patients with acute upper gastrointestinal bleeding.

[Treatment approach of hepatocellular carcinoma in Spain. Analysis of 705 patients from 62 centers]. / Tratamiento del carcinoma hepatocelular en España. Análisis de 705 casos en 62 centros.

BACKGROUND AND OBJECTIVE: Hepatocellular carcinoma (HCC) is the leading cause of death in patients with cirrhosis and its current situation in Spain is not well known. Therefore, a national registry was created to assess the characteristics of patients with de novo HCC. PATIENTS AND METHOD: Between 1/10/2008 and 31/1/2009, 62 centers reported the baseline demographic, clinical and tumor characteristics, the first choice of treatment and eligibility for transplantation (OLT) of HCC diagnosed during this time. RESULTS: There were 705 new cases of HCC, 78% men, mean age 65 years, 89% cirrhosis (58% Child-Pugh class A, 42% HCV, 30% alcohol). Only 334 cases (47%) were diagnosed by screening. The size of the main nodule and BCLC stage were significantly lower in the screening group than in the rest (p<0.001). The applicability of radical therapies (resection and percutaneous ablation) was significantly higher (47.5% versus 24.6%, p<0.001) as well as the evaluation for OLT (31% versus 12%, p<0.001). The screening did not differ according to gender (p=0.204) or age (<50 years, <65, <75, >75 years) (p=0.171). Chemoembolization was the most common treatment: initial tumors (46.4%), tumors >5 cm (15.7%), multifocal HCC (37.9%) and as a bridge to OLT (33%). CONCLUSION: The majority of HCC patients are diagnosed in Spain out of early detection programs, and this limits the chance for early diagnosis and effective therapy.

Portal hypertension-related complications after acute portal vein thrombosis: impact of early anticoagulation.

BACKGROUND & AIMS: Acute portal vein thrombosis (APVT) is a rare disorder that causes chronic portal hypertension if recanalization is not obtained. However, response to anticoagulation and long-term prognosis of APVT are not well-defined. METHODS: Thirty-eight patients diagnosed with APVT between 1995 and 2003 from 5 Spanish referral hospitals, in whom cirrhosis and malignancy were specifically excluded, were included in this retrospective study. The response to anticoagulation therapy and development of portal hypertension-related complications during follow-up were evaluated. RESULTS: Mean follow-up was 43 months (range, 6-112 months). Recanalization occurred in 12 of 27 patients receiving anticoagulation versus 0 of 11 patients who did not receive anticoagulation (P = .008). Rates of recanalization were influenced by the precocity of heparin administration and the number of underlying prothrombotic conditions. Follow-up upper endoscopy performed in 29 patients disclosed gastroesophageal varices in 16 (55%). Varices appeared as early as 1 month after APVT. However, in most patients varices were detected in successive endoscopies, mainly during the first year. Two-year actuarial probability of variceal bleeding was 12% and for ascites 16%. Five-year survival was 87%. Mortality was related to the APVT episode in 2 cases and to an underlying hematologic disorder in one. CONCLUSIONS: Anticoagulation achieved recanalization in about 40% of patients. Most patients not achieving recanalization will develop gastroesophageal varices during follow-up. However, development of variceal bleeding and ascites is infrequent, and survival is satisfactory.

A randomized controlled trial comparing ligation and sclerotherapy as emergency endoscopic treatment added to somatostatin in acute variceal bleeding.

BACKGROUND/AIMS: The currently recommended treatment for acute variceal bleeding is the association of vasoactive drugs and endoscopic therapy. However, which emergency endoscopic treatment combines better with drugs has not been clarified. This study compares the efficacy and safety of variceal ligation and sclerotherapy as emergency endoscopic treatment added to somatostatin. METHODS: Patients admitted with acute gastrointestinal bleeding and with suspected cirrhosis received somatostatin infusion (for 5 days). Endoscopy was performed within 6h and those with esophageal variceal bleeding were randomized to receive either sclerotherapy (N=89) or ligation (N=90). RESULTS: Therapeutic failure occurred in 21 patients treated with sclerotherapy (24%) and in nine treated with ligation (10%) (RR=2.4, 95% CI=1.1-4.9). Failure to control bleeding occurred in 15% vs 4%, respectively (P=0.02). Treatment group, shock and HVPG >16 mmHg were independent predictors of failure. Side-effects occurred in 28% of patients receiving sclerotherapy vs 14% with ligation (RR=1.9, 95% CI=1.1-3.5), being serious in 13% vs 4% (P=0.04). Six-week survival probability without therapeutic failure was better with ligation (P=0.01). CONCLUSIONS: The use of variceal ligation instead of sclerotherapy as emergency endoscopic therapy added to somatostatin for the treatment of acute variceal bleeding significantly improves the efficacy and safety.
