Giant hepatocellular carcinoma in non-cirrhotic liver: Treatment with ALPPS and MINIALPPS

Background: Oncological resection of liver tumors continues to be the best alternative to increase survival and the disease-free period of patients. Thanks to liver regeneration, liver hypertrophy techniques are a great alternative in the surgical management of patients with high tumor burden. A few years ago, a surgical technique for liver hypertrophy called ALPPS (Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy) was described. In recent years, groups in Chile and Argentina have developed a variant of this which they have called MINIALPPS.

Outcome after Resection for Hepatocellular Carcinoma in Noncirrhotic Liver-A Single Centre Study.

Liver cirrhosis is the most common risk factor for the development of hepatocellular carcinoma (HCC). However, 10 to 15% of all HCC arise in a non-cirrhotic liver. Few reliable data exist on outcome after liver resection in a non-cirrhotic liver. The aim of this single-centre study was to evaluate the outcome of resection for HCC in non-cirrhotic liver (NC-HCC) and to determine prognostic factors for overall (OS) and intrahepatic recurrence-free (RFS) survival. From 2008 to 2020, a total of 249 patients were enrolled in this retrospective study. Primary outcome was OS and RFS. Radiological and pathological findings, such as tumour size, number of nodules, Tumour-, Nodes-, Metastases- (TNM) classification and vascular invasion as well as extent of surgical resection and laboratory liver function were collected. Here, 249 patients underwent liver resection for NC-HCC. In this case, 50% of patients underwent major liver resection, perioperative mortality was 6.4%. Median OS was 35.4 months (range 1–151 months), median RFS was 10.5 months (range 1–128 moths). Tumour diameter greater than three centimetres, multifocal tumour disease, vascular invasion, preoperative low albumin and increased alpha-fetoprotein (AFP) values were associated with significantly worse OS. Our study shows that resection for NC-HCC is an acceptable treatment approach with comparatively good outcome even in extensive tumours.

Differentiation of hepatocellular adenoma by subtype and hepatocellular carcinoma in non-cirrhotic liver by fractal analysis of perfusion MRI

BackgroundTo investigate whether fractal analysis of perfusion differentiates hepatocellular adenoma (HCA) subtypes and hepatocellular carcinoma (HCC) in non-cirrhotic liver by quantifying perfusion chaos using four-dimensional dynamic contrast-enhanced magnetic resonance imaging (4D-DCE-MRI).ResultsA retrospective population of 63 patients (47 female) with histopathologically characterized HCA and HCC in non-cirrhotic livers was investigated. Our population consisted of 13 hepatocyte nuclear factor (HNF)-1α-inactivated (H-HCAs), 7 β-catenin-exon-3-mutated (bex3-HCAs), 27 inflammatory HCAs (I-HCAs), and 16 HCCs. Four-dimensional fractal analysis was applied to arterial, portal venous, and delayed phases of 4D-DCE-MRI and was performed in lesions as well as remote liver tissue. Diagnostic accuracy of fractal analysis was compared to qualitative MRI features alone and their combination using multi-class diagnostic accuracy testing including kappa-statistics and area under the receiver operating characteristic curve (AUC). Fractal analysis allowed quantification of perfusion chaos, which was significantly different between lesion subtypes (multi-class AUC = 0.90, p < 0.001), except between I-HCA and HCC. Qualitative MRI features alone did not allow reliable differentiation between HCA subtypes and HCC (κ = 0.35). However, combining qualitative MRI features and fractal analysis reliably predicted the histopathological diagnosis (κ = 0.89) and improved differentiation of high-risk lesions (i.e., HCCs, bex3-HCAs) and low-risk lesions (H-HCAs, I-HCAs) from sensitivity and specificity of 43% (95% confidence interval [CI] 23–66%) and 47% (CI 32–64%) for qualitative MRI features to 96% (CI 78–100%) and 68% (CI 51–81%), respectively, when adding fractal analysis.ConclusionsCombining qualitative MRI features with fractal analysis allows identification of HCA subtypes and HCCs in patients with non-cirrhotic livers and improves differentiation of lesions with high and low risk for malignant transformation.

Higher Accumulation of Visceral Adipose Tissue Is an Independent Risk Factor for Hepatocellular Carcinoma among Viral Hepatitis Patients with Non-Cirrhotic Livers.

Simple SummaryHepatocellular carcinoma (HCC) occurring in non-cirrhotic livers is often overlooked in clinical practice because the present HCC surveillance strategies usually focus only on patients with cirrhotic livers. This study aimed to determine the risk factors for HCC among viral hepatitis patients with non-cirrhotic livers. The findings of this study could be very useful in detecting HCC at an early stage, especially in patients with viral hepatitis who may not have developed extensive cirrhosis.This study aimed to determine the risk factors for hepatocellular carcinoma in non-cirrhotic livers among viral hepatitis patients. A total of 333 HCC cases, including 69 hepatitis B virus (HBV)-related and 264 hepatitis C virus (HCV)-related, were divided into cirrhotic (Fibrosis-4 [FIB-4] index > 3.25) and non-cirrhotic groups (FIB-4 index ≤ 3.25). The clinical characteristics of the two groups were compared. The independent risk factors for the development of HCC were analyzed using logistic regression analysis. The patients with HBV-related HCC were significantly younger, had better Child-Pugh scores, lower FIB-4 index and Mac-2 binding protein glycosylated isomers (M2BPGi) levels, more progressive cancer stage, and higher alpha-fetoprotein (AFP) levels than those with HCV-related HCC. Diabetes mellitus and hypertension were less common in patients with HBV-related HCC. The non-cirrhotic group with HBV-related HCC had a higher visceral adipose tissue index (VATI), better Child-Pugh score, and higher hemoglobin A1c (HbA1c), whereas the one with HCV-related HCC had a higher proportion of men, higher VATI, better Child-Pugh score, higher HbA1c, and a higher prevalence of hypertension, than the corresponding cirrhotic groups. Logistic regression analyses demonstrated that age, male sex, VATI, HbA1c, the presence of hypertension, and HBV etiology were independent risk factors for HCC in a non-cirrhotic liver. A high accumulation of VAT is a risk factor for HCC in patients with non-cirrhotic livers.

Hepatocellular Carcinoma in Non-cirrhotic Liver Arises with a More Advanced Tumoral Appearance: A Single-Center Cohort Study.

A small proportion of all hepatocellular carcinomas (HCCs) arise in a non-cirrhotic liver (NCL). However, our knowledge about the HCCs developing in a NCL is scarce. This study was undertaken to investigate the characteristics and survival course of this patient group. We retrospectively analyzed the database of patients with HCC at a tertiary center during a 10-year period (2009-2019). All demographic, clinical, laboratory, and tumoral features with survival outcomes were compared between the HCC-CL and HCC-NCL groups. Out of 384 HCC cases, 11.2% (n = 43) had no cirrhosis. The dominant etiology in the HCC-NCL group was hepatitis B virus (n = 26, 60.5%), followed by non-alcoholic fatty liver disease (n = 10, 23.2%), and hepatitis C virus (n = 7, 16.3%). The maximum tumor diameter was approximately 2 times larger in the HCC-NCL group (HCC-NCL: 90 mm vs. HCC-CL: 46.5 mm, P < .001). The proportion of patients with vascular (HCC-NCL: 27.9% vs. HCC-CL: 8.6%, P < .001) and extrahepatic invasion (HCC-NCL: 14% vs. HCC-CL: 3%, P = .001) were prominently higher in the HCC-NCL group. Patients with HCC-NCL were less often detected in early-curable stages (BCLC 0-A) than those in the HCC-CL group (HCC-NCL: 16.3% vs. HCC-CL: 34.9%, P = .004). The overall survival was not different between the 2 groups (HCC-NCL: 19.4 ± 9.8 months vs. HCC-CL: 17.5 ± 2.3 months, P = .581). HCC in NCL is diagnosed at more advanced tumoral stages with larger tumor size and more often with vascular and extrahepatic spread. Despite the preserved liver functions, the overall survival is not prolonged in HCCs without cirrhosis, due to the late recognition.

Hemoperitoneum caused by spontaneous rupture of hepatocellular carcinoma in noncirrhotic liver. A case report and systematic review.

IntroductionHepatocellular carcinoma (HCC) is the sixth most common cancer. Spontaneous rupture of HCC is an acute complication with a high mortality rate. The HCC principally arises in the background of chronic liver disease and cirrhosis of the liver. In the last few years, the rising incidence of HCC in noncirrhotic liver suggests the presence of other factors that may play a role in liver carcinogenesis.MethodsWe reviewed all cases treated at the University Surgical Department of Ospedali Riuniti of Foggia from 2009 to 2018. Only a single case of hemoperitoneum caused by spontaneous rupture of HCC in noncirrhotic liver was found. An extensive search of the relevant literature was carried out using MEDLINE, and a total of 58 published studies were screened from the sources listed.ConclusionsThe management of this devastating emergency should be carefully analyzed, with stabilization of vital signs as soon as possible. Patient with ruptured HCC and hemoperitoneum without a prior history of cirrhosis and viral infections benefited from the role of transcatheter arterial embolization (TAE) as the preliminary treatment in order to have a more precise diagnosis and an optimal stabilization of the patient. Delayed or staged hepatectomy after TAE represents the definitive treatment.

New frontiers in liver resection for hepatocellular carcinoma.

SummaryLiver resection is one of the main curative options for early hepatocellular carcinoma (HCC) in patients with cirrhosis and is the treatment of choice in non-cirrhotic patients. However, careful patient selection is required to balance the risk of postoperative liver failure and the potential benefit on long-term outcomes. In the last decades, improved surgical techniques and perioperative management, as well as better patient selection, have enabled the indications for liver resection to be expanded. In this review, we aim to describe the main indications for liver resection in the management of HCC, its role compared to percutaneous ablation and liver transplantation in the therapeutic algorithm, as well as the recent advances in liver surgery that could be used to improve the prognosis of patients with HCC.

Hepatocellular carcinoma in the non-cirrhotic liver: a two-center experience with 19 cases

Background: Hepatocellular carcinoma is the most common type of primary liver cancer and is the third cause of cancer related deaths; 80% of the HCC are associated with cirrhotic livers or chronic liver diseases, which constitute the main risk factor. Chronic inflammation, necrosis and regeneration due to these conditions produce genetic mutation and development of tumor cells. Yet, 10% develop in non-cirrhotic healthy livers without precipitating factors. Material and methods: We conducted a retrospective analysis of the characteristics and survival of patients with diagnosis of hepatocellular carcinoma in non-cirrhotic liver and absence of a history of liver cirrhosis or chronic liver disease undergoing surgery in two hepato-pancreato-biliary units between January 2007 and January 2016. Results: Mean age was 65 years and 13 patients were men. Abdominal pain was the most common clinical presentation. Liver panel was normal in 60% of the cases and alpha-fetoprotein was elevated in only 16%. The diagnosis was made by imaging tests in 61% of the cases. Mean tumor size was 110.6 cm. All the patients underwent surgery. Complications were observed in 36.8% of the patients and survival at 5 years was 62.3%. Conclusion: hepatocellular carcinoma is usually diagnosed as a large lesion in imaging tests ordered due to abdominal pain. Surgery provides curative treatment, and large resections can be safely performed, with low perioperative morbidity and mortality and low incidence of postoperative liver failure,since the liver remnant is healthy and liver function is maintained.

Surgical treatment results of hepatocellular carcinoma in non-cirrhotic liver in southern Chile: case series with follow-up.

Hepatocellular carcinoma is the most frequent primary tumour of the liver. Although often associated with chronic liver disease, it can also occur in non-cirrhotic livers. The aim of this study was to describe post-operative morbidity (POM), and survival of patients with hepatocellular carcinoma in non-cirrhotic liver treated surgically, and to identify variables associated with prognosis. Case series of patients who underwent surgery for hepatocellular carcinoma in non-cirrhotic liver at Clínica RedSalud Mayor de Temuco, Chile (2001-2017), were studied. The minimum follow-up time considered was 12 months. Principal outcomes were development of POM and survival. Other variables of interest were age, sex, tumour diameter, surgical time, hospital stay, follow-up time, need for surgical re-intervention, mortality, vascular and lymph node invasion and staging. Descriptive and analytic statistics were calculated. A total of 32 patients were studied. They were characterized by a mean age of 67.3 ± 7.2 years, 62.5% of whom were men. Averages of tumour diameter, surgical time and hospitalization were 12.0 ± 2.6 cm, 114.4 ± 32.3 min and 7.2 ± 2.9 days, respectively. POM was 31.3%. There was no mortality and there were no re-interventions. The overall actuarial survival at 1, 2 and 3 years was 96.8%, 73.4% and 17.3%, respectively. Lower survival was verified in patients with vascular invasion, lymph node infiltration and stages III and IVa. Despite the tumour diameter and extent of the resections, POM in patients with hepatocellular carcinoma in non-cirrhotic liver is moderate. However, its prognosis is poor. Vascular invasion, lymph node invasion and advances stages were associated with worse survival.

Development and validation of a risk score to predict the overall survival following surgical resection of hepatocellular carcinoma in non-cirrhotic liver

BackgroundThe aim of this study was to develop and validate a risk score to predict overall survival (OS) in patients undergoing surgical resection for hepatocellular carcinoma in non-cirrhotic liver (NC-HCC). MethodsPatients who underwent resection for NC-HCC between 2004 and 2013 were identified from the SEER database. A derivation set of 75% of this cohort was used to develop a risk score. This was then internally validated on the remaining patients, and externally validated using a cohort of patients from The HPB Unit, Birmingham, UK. ResultsA total of 3897 patients were included from the SEER database, with a median post-diagnosis survival of 59 months. In the derivation set, multivariable analyses identified male sex, increasing tumour size, the presence of multiple tumours, bilobar tumours and major vascular invasion as adverse prognostic factors. A risk score generated from these factors was significantly predictive of OS, and was used to classify patients into low, medium and high-risk groups. These groups had a five-year OS of 69%, 51% and 19% in the internal, and 73%, 50% and 45% in the external validation sets. ConclusionThe proposed risk score is useful in the selection, pre-operative consenting and counselling of patients for surgery and to allow patients to make an informed decision regarding treatment.

Characteristics and survival of hepatocellular carcinoma in non-cirrhotic liver.

the characteristics, screening, and survival of hepatocellular carcinoma (HCC) for patients without cirrhosis have not been fully studied. A retrospective cohort study was performed in non-cirrhotic patients with histological HCC, between January 2004 and October 2018. Their characteristics, treatment, follow-up and overall survival were described. 25 of the 332 patients with HCC met the inclusion criteria (7.5%), 76% were males and the median age was 69.9 years. The main etiology of liver disease was the hepatitis B virus (HBV) (32%), followed by non-alcoholic steatohepatitis (NASH) (20%). Liver fibrosis was mild (0-1) in 44% of cases. The nodule was diagnosed by ultrasonography in 32% of cases, 60% were found incidentally and 8% due to clinical symptoms. The Barcelona Clinic Liver Cancer (BCLC) staging was 0 in 4% of cases, A in 88%, B in 4% and C in 4%. The main initial treatment was surgical resection (76%) and 8% refused to be treated. Percutaneous ethanol injection, chemoembolization, sorafenib and palliative care were each performed in 4% of cases. There were some complications in 21% of patients treated with surgery, half of them were severe. The median follow-up was 22.2 (2.9-150.6) months and 56% were in remission and the median overall survival was 57.4 ± 29.8 months. The overall cumulative survival at 1, 3 and 5 years was 84%, 61.6% and 47.9%, respectively. 7.5% of HCC presented without cirrhosis and almost half of patients had mild fibrosis. HBV was the main cause of HCC, followed by NASH. The most frequent BCLC stage at diagnosis was early stage and surgery was the most common treatment. Overall cumulative survival at 5 years was almost 50%.

A rare presentation of hepatocellular carcinoma in non-cirrhotic liver

Hepatocellular carcinoma is the most frequent type of liver malignancy. Most cases of hepatocellular carcinoma are secondary to either viral hepatitis (hepatitis B, C) or alcoholic cirrhosis. Liver cirrhosis due to any other causes is considered as a risk factor for development of hepatocellular carcinoma; however, hepatocellular carcinoma in non cirrhotic livers remains a rare condition. The present case report describes a 59-year-old woman patient admitted to explore right hypochondriac and epigastric pain, with no evidence of pre-existing liver disease and with a good general condition. The computed tomography was very suggestive of a gastro-intestinal stromal tumor. But, at laparotomy, a huge hepatic tumor was discovered. Histopathological study confirmed the presence of primary hepatocellular carcinoma. Hepatocellular carcinoma occurs more frequently on a cirrhotic liver. However, it can occur on a non cirrhotic liver and remains and extremely rare case.

Hepatocellular carcinoma arising in adenoma: similar immunohistochemical and cytogenetic features in adenoma and hepatocellular carcinoma portions of the tumor

Well-differentiated hepatocellular carcinoma in non-cirrhotic liver can show morphological features similar to hepatocellular adenoma. In rare instances, hepatocellular carcinoma can arise in the setting of hepatocellular adenoma. This study compares the immunohistochemical and cytogenetic features of the hepatocellular adenoma-like and hepatocellular carcinoma portions of these tumors. Immunohistochemistry for β-catenin, glutamine synthetase, serum amyloid A protein, glypican-3, and heat-shock protein 70 was done in 11 cases of hepatocellular carcinoma arising in hepatocellular adenoma in non-cirrhotic liver. Tumors with nuclear β-catenin and/or diffuse glutamine synthetase were considered β-catenin activated. Fluorescence in situ hybridization (FISH) was done in nine cases for gains of chromosomes 1, 8 and MYC. There were seven men (33–75 years) and four women (29–65 years). Focal atypical morphological features were seen in hepatocellular adenoma-like areas in 7 (64%) cases. Hepatocellular adenoma-like areas showed features of inflammatory hepatocellular adenoma in 7 (64%) cases; 4 of these were also serum amyloid A-positive in the hepatocellular carcinoma portion. β-Catenin activation, heat-shock protein 70 positivity, and chromosomal gains on FISH were seen in the hepatocellular adenoma portion in 55%, 40%, and 56% of cases, and 73%, 60%, and 78% of cases in the hepatocellular carcinoma portion, respectively. In conclusion, the hepatocellular adenoma-like portion of most cases of hepatocellular carcinoma arising in hepatocellular adenoma shows features typically seen in hepatocellular carcinoma such as focal morphological abnormalities, β-catenin activation, heat-shock protein 70 expression, and chromosomal gains. Hepatocellular adenoma-like areas in these tumors, especially in men and older women, may represent an extremely well-differentiated variant of hepatocellular carcinoma, whereas the morphologically recognizable hepatocellular carcinoma portion represents a relatively higher grade component of the tumor.

Abstract 5181: Genomic and transcriptomic somatic alterations of hepatocellular carcinoma in non-cirrhotic livers

Abstract Background: In 2014, it is estimated that there will be over 30,000 new cases of hepatocellular carcinoma (HCC) and an estimated 20,000 subjects will die of this disease in the U.S. alone. Risk factors include chronic HBV/HCV infections, cirrhosis, alcohol abuse, diabetes, and fatty liver disease. However, an important subset of HCC occurs in the absence of any such risk factors. We surveyed the genomic and transcriptomic landscape of this subset of HCC. Methods: We performed whole genome and transcriptome sequencing of 30 matched tumor and non-tumor liver samples from resections performed at Washington University School of Medicine. Somatic variants identified in this discovery set were extended to a set of 89 additional cases by custom capture sequencing for a total of 119 HCCs profiled. All data were processed through The Genome Institute's Genome Modeling System (GMS) to analyze for viral integrations, SNVs, Indels, CNVs, fusions, SVs, expression and differential expression. Results: We report here for the first time the unique landscape of somatic alterations of HCC arising in non-cirrhotic liver. We detected and validated over 3,010 SNVs and indels in coding regions and 2,390 fusion transcripts, as well as extensive copy number and expression changes. We identified a single undiagnosed HBV case with viral integration occurring at the TERT promoter. We also confirmed recent reports of a recurrent TERT promoter mutation (G1295228A) occurring in at least 56% of cases. Additional recurrent mutations were observed in previously reported genes such as CTNNB1, TP53, AXIN1, and ARID1A, along with an increased frequency of RB1 loss, novel recurrent mutations of APOB, fusions in NR1H4, and other alterations. These molecular features were tested for association with clinical variables and outcome. Pathway analysis of recurrently altered genes suggests that, in the absence of external factors, genomic aberrations in basic liver metabolism genes may promote malignant transformation to HCC.

Recurrence Patterns and Prognostic Factors in Patients with Hepatocellular Carcinoma in Noncirrhotic Liver: A Multi-Institutional Analysis

Hepatocellular carcinoma (HCC) primarily affects patients with a cirrhotic liver. Reports on the characteristics of patients with HCC in noncirrhotic liver, as well as predictors of recurrence and survival, are scarce. Between 1992 and 2011, 334 patients treated for HCC in noncirrhotic liver were identified from three major hepatobiliary centers. Clinicopathological characteristics were analyzed and independent predictors of recurrence and overall survival were identified using Cox proportional hazards models. Median patient age was 58 years and 77 % were male. Most patients had a solitary (81 %) and poorly or undifferentiated tumor (56 %); median size was 6.5 cm. The majority of patients (96 %) underwent liver resection (microscopically negative margins in 94 %), whereas a few had transarterial chemoembolization or transplantation (4 %). Median recurrence-free survival (RFS) was 2.5 years, and 1- and 5-year RFS was 71.1, and 35 %, respectively. Elevated alkaline phosphatase levels [hazards ratio (HR) = 1.82], poor tumor differentiation (HR = 1.4), macrovascular invasion (HR = 2.18), and the presence of satellite lesions (HR = 1.9), or intrahepatic metastases (HR = 2.59) were independently associated with shorter RFS; in contrast, an intact tumor capsule independently prolonged RFS (HR = 0.46). Median overall survival was 5.9 years, and 1- and 5-year overall survival was 86.9, and 54.5 %, respectively. Tumor size ≥5 cm (HR = 2.27), macrovascular (HR = 2.72) or adjacent organ invasion (HR = 3.34), and satellite lesions (HR = 2.18) were independently associated with shorter overall survival, whereas an intact tumor capsule showed a protective effect (HR = 0.51). Following resection of HCC in the setting of no cirrhosis, more than one-half of patients were alive after 5 years. However, even among patients with no cirrhosis, recurrence was common. Factors associated with RFS and overall survival included tumor characteristics, such as tumor capsule, satellite lesions, and vascular invasion.

Recurrence of Hepatocellular Carcinoma in Noncirrhotic Liver After Hepatectomy

Hepatocellular carcinoma in noncirrhotic liver (HCCNC) is rare. This tumor has a particular epidemiology and presentation, and it requires specific treatment, compared with HCC in cirrhotic liver. The aims of this study were to determine the survival and recurrence rates, prognostic factors, and optimum treatment of HCCNC and to propose a follow-up protocol for patients who have undergone surgery for HCCNC. This study included 131 patients who underwent surgical treatment for HCCNC from January 1992 to December 2010. Survival and recurrence rates were evaluated, and the prognostic factors and characteristics of recurrence were analyzed. Pathologic characteristics of the tumors and the nontumoral liver were examined. The mean survival time was 67.9 months. The 5- and 10-year overall survival rates were 72.9 and 36.7 %, respectively. In all, 54 patients (41.2 %) developed recurrence at a median interval of 30.96 months. Of these recurrences, 31.5 % occurred during the first year, and 24.1 % occurred more than 5 years after surgery. Macro- or microvascular invasion and tumor size >5 cm were significantly associated with a poor survival rate. The predictive factors for recurrence were multiple tumors, tumor diameter >5 cm, and satellite nodules. Patients who underwent surgical treatment for recurrence had a significantly longer survival time than those who did not (p < 0.0292). Recurrence is the most common cause of death after hepatectomy for HCC, and patients should undergo careful, long-term follow-up. Early detection and treatment of recurrence with curative intent should improve the prognosis of these patients.
