Immunotherapy treatment responses in hepatocellular carcinoma patients with nonalcoholic fatty liver disease cirrhosis.

e16199 Background: Primary liver cancer is the third most frequent cause of cancer-related death worldwide, with hepatocellular carcinoma (HCC) composing 75% of cases. Recent preclinical models suggest that immunotherapy targeting programmed cell death protein 1 (PD-1) leads to CD8+ T-cell activation but not tumor regression in nonalcoholic fatty liver disease (NAFLD) induced HCC. However, additional studies are required to understand the response of NAFLD-associated HCC patients to PD-1 and programmed death-ligand 1 (PD-L1) therapies. Methods: Our team conducted a retrospective, single center study to determine the best responses to anti-PD-1/PD-L1 containing regimens in patients with HCC and underlying NAFLD cirrhosis. There were 2 groups included in this study: patients with HCC associated with NAFLD cirrhosis and those who had HCC without NAFLD cirrhosis. All patients included in this study received either an anti-PD-1/PD-L1 targeted agent as monotherapy or combined with other systemic treatment. Radiologic evaluations were conducted between February 2018 and January 2022. Results: There were 81 patients were included in this study: 15 in the NAFLD cirrhosis HCC group and 66 in the HCC group without NAFLD cirrhosis. When determining the best responses to anti-PD-1/PD-L1 therapies, 6 patients (40%) with HCC and NAFLD cirrhosis had disease progression as their best responses versus 7 patients (10.6%) who had HCC without NAFLD cirrhosis (risk ratio 3.8, p = 0.012). Furthermore, in the HCC group without NAFLD cirrhosis, 59 patients (89.4%) experienced disease control (defined as stable disease, partial response, or complete response) from anti-PD-1/PD-L1 containing regimens compared to 9 patients (60%) in the NAFLD cirrhosis-related HCC group (risk ratio 1.5, p = 0.012). No significant differences were found in gender, patient age, or treatment regimens received between the two groups. See the table below for details on immunotherapy regimens and treatment responses. Conclusions: In this study, HCC patients with NAFLD cirrhosis experienced significantly higher rates of disease progression as the best response to anti-PD-1/PD-L1 therapies compared to HCC patients without NAFLD cirrhosis. As the use of immunotherapy in the HCC population continues to expand, additional prospective studies are necessary to clarify the impact of underlying liver disease on treatment response.[Table: see text]

Responses to immunotherapy in hepatocellular carcinoma patients with nonalcoholic steatohepatitis cirrhosis.

389 Background: Hepatocellular carcinoma (HCC) is the most rapidly growing cause of cancer-related mortality in the United States. Recent preclinical studies suggest that immunotherapy agents targeted at programmed cell death protein 1 (PD-1) do not lead to tumor regression in HCC with underlying nonalcoholic steatohepatitis (NASH). However, further clinical studies are needed to clarify the impact of immunotherapy on patients with NASH-related HCC. Methods: This was a single center, retrospective study analyzing the best responses to immunotherapy in patients with HCC and underlying cirrhosis due to NASH. Patients were divided into 2 groups: those with HCC related to NASH cirrhosis and those with HCC without NASH cirrhosis. All patients received immunotherapy, either as a single agent or in combination with other cancer-directed therapy, with response assessments conducted during their treatment courses. Results: A total of 79 patients were included in this study. There were 15 patients in the NASH cirrhosis-related HCC group and 64 patients in the HCC group without NASH cirrhosis. When analyzing the best disease responses to immunotherapy, 7 patients (46.7%) with HCC and NASH cirrhosis were found to have disease progression as their best responses compared to 7 patients (10.9%) who had HCC without NASH cirrhosis (risk ratio 4.27, p = 0.004). In addition, for the group without NASH cirrhosis, 57 patients (89.1%) experienced disease control (stable disease, partial response, or complete response) from immunotherapy versus 8 patients (53.3%) in the NASH cirrhosis-related HCC group (risk ratio 1.67, p = 0.004). There were no notable differences in patient age, gender, or immunotherapy agents received between the two groups, but there was a significantly greater proportion of patients of Hispanic ethnicity in the HCC group with NASH cirrhosis (p = 0.006, full patient characteristics listed in the table). However, when looking at all individuals in the study, patients of Hispanic ethnicity were not found to have a significantly higher risk of disease progression compared to non-Hispanic patients (p = 0.07). Conclusions: There were significantly higher rates of disease progression as the best response to immunotherapy in patients with HCC and NASH cirrhosis compared to those without NASH cirrhosis. With the expanded use of immunotherapy in HCC patients, further prospective studies are needed to clarify the impact of underlying liver disease etiology on immunotherapy response.[Table: see text]

Sequential Portal Vein Embolization and Percutaneous Radiofrequency Ablation for Future Liver Remnant Growth: A Minimally Invasive Alternative to ALPPS Stage-1 in Treatment of Hepatocellular Carcinoma.

Background: To evaluate the feasibility and efficacy of sequential portal vein embolization (PVE) and radiofrequency ablation (RFA) (PVE+RFA) as a minimally invasive variant for associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) stage-1 in treatment of cirrhosis-related hepatocellular carcinoma (HCC).Methods: For HCC patients with insufficient FLR, right-sided PVE was first performed, followed by percutaneous RFA to the tumor as a means to trigger FLR growth. When the FLR reached a safe level (at least 40%) and the blood biochemistry tests were in good condition, the hepatectomy was performed. FLR dynamic changes and serum biochemical tests were evaluated. Postoperative complications, mortality, intraoperative data and long-term oncological outcome were also recorded.Results: Seven patients underwent PVE+RFA for FLR growth between March 2016 and December 2019. The median baseline of FLR was 353 ml (28%), which increased to 539 (44%) ml after 8 (7–18) days of this strategy (p < 0.05). The increase of FLR ranged from 40% to 140% (median 47%). Five patients completed hepatectomy. The median interval between PVE+RFA and hepatectomy was 19 (15–27) days. No major morbidity ≥ III of Clavien-Dindo classification or in-hospital mortality occurred. One patient who did not proceed to surgery died within 90 days after discharge. After a median follow-up of 18 (range 3–50) months, five patients were alive.Conclusion: Sequential PVE+RFA is a feasible and effective strategy for FLR growth prior to extended hepatectomy and may provide a minimally invasive alternative for ALPPS stage-1 for treatment of patients with cirrhosis-related HCC.

Screening, clinical features and prognostic analysis of liver cirrhosis-related hepatocellular carcinoma

Objective To explore the impact of the screening interval and methods on cirrhosis-related hepatocellular carcinoma (HCC) detection and to analyse the clinical features and prognosis of HCC. Materials and methods We recruited 3000 patients diagnosed with liver cirrhosis, who had been treated at the First Affiliated Hospital of Anhui Medical University from January 2016 to January 2020. The time of admission was divided into 3- (group A, 539 cases), 6- (group B, 1012 cases), and 12-month screening groups (group C, 1449 cases). We compared the detection rate of small HCCs in each group and analysed the clinical characteristics and prognosis of the patients with HCC. Results We detected a total of 124 HCC cases, including 41 cases of small HCC: 21, 14, and 6 cases in groups A, B, and C, respectively. The detection rate was 3.9% (21/539) in group A, which was significantly higher than that in groups B and C (χ 2 = 31.186, p < .001). Single small, right liver lobe, and alpha-fetoprotein-negative HCCs accounted for 90.2%, 73.2%, and 68.3%, respectively. We detected vascular invasion and lymph node metastasis in one and three cases, respectively. The average survival time of patients in the small HCC group was significantly higher than that in the non-small-HCC group (35.68 ± 12.95 vs. 22.87 ± 11.42 months) (t = 5.623, p < .001). Conclusions Screening patients with a history of liver cirrhosis at intervals of 3 months can increase the detection rate of small HCCs. Early detection can provide more patients with an opportunity for radical treatment and prolong their survival.

Rescue radiofrequency ablation or percutaneous ethanol injection: a strategy for failed RALPPS stage-1 in patients with cirrhosis-related hepatocellular carcinoma

BackgroundThe future liver remnant (FLR) faces a risk of poor growth in patients with cirrhosis-related hepatocellular carcinoma (HCC) after stage-1 radiofrequency-assisted ALPPS (RALPPS). The present study presents a strategy to trigger further FLR growth using supplementary radiofrequency ablation (RFA) and percutaneous ethanol injection (PEI).MethodsAt RALPPS stage-1 the portal vein branch was ligated, followed by intraoperative RFA creating a coagulated avascular area between the FLR and the deportalized lobes. During the interstage period, patients not achieving sufficient liver size (≥ 40%) within 2–3 weeks underwent additional percutaneous RFA/PEI of the deportalized lobes (rescue RFA/PEI) in an attempt to further stimulate FLR growth.ResultsSeven patients underwent rescue RFA/PEI after RALPPS stage-1. In total five RFAs and eight PEIs were applied in these patients. The kinetic growth rate (KGR) was highest the first week after RALPPS stage-1 (10%, range − 1% to 15%), and then dropped to 1.5% (0–9%) in the second week (p < 0.05). With rescue RFA/PEI applied, KGR increased significantly to 4% (2–5%) compared with that before the rescue procedures (p < 0.05). Five patients proceeded to RALPPS stage-2. Two patients failed: In one patient the FLR remained at a constant level even after four rescue PEIs. The other patient developed metastasis. Except one patient died after RALPPS stage-2, no severe complications (Clavien-Dindo ≥ IIIb) occurred among remaining six patients.ConclusionsRescue RFA/PEI may provide an alternative to trigger further growth of the FLR in patients with cirrhosis-related HCC showing insufficient FLR after RALPPS stage-1.Trial registration Retrospectively registered.

Cooperative Role of Thrombopoietin and Vascular Endothelial Growth Factor-A in the Progression of Liver Cirrhosis to Hepatocellular Carcinoma.

Primary thrombopoietic mediator thrombopoietin (THPO) is mainly produced by the liver; it may act as a growth factor for hepatic progenitors. Principal angiogenesis inducer vascular endothelial growth factor-A (VEGF-A) is critical for the complex vascular network within the liver architecture. As a cross-regulatory loop between THPO and VEGF-A has been demonstrated in the hematopoietic system, the two growth factors were hypothesized to cooperatively contribute to the progression from liver cirrhosis (LC) to hepatocellular carcinoma (HCC). The mRNA and protein expression levels of THPO, VEGF-A, and their receptors were examined, compared, and correlated in paired cancerous and LC tissues from 26 cirrhosis-related HCC patients, using qRT-PCR and immunohistochemistry. THPO and VEGF-A were alternatively silenced by small interfering RNA (siRNA) in human liver cancer cell lines Huh7 and HepG2. THPO and VEGF-A expressions significantly increased in tumor versus LC tissues. HCC and paired LC cells expressed similar levels of THPO receptor (R), whereas vascular endothelial growth factor receptor (VEGFR) -1 and VEGFR-2 levels were higher in HCC than in corresponding LC tissue samples. A significant linear correlation emerged between THPO and VEGF-A transcripts in HCC and, at the protein level, THPO and THPOR were significantly correlated with VEGF-A in tumor tissues. Both HCC and LC expressed similar levels of gene and protein hypoxia inducible factor (HIF)-1α. Positive cross-regulation occurred with the alternative administration of siRNAs targeting THPO and those targeting VEGF-A in hypoxic liver cancer cell lines. These results suggest THPO and VEGF-A might act as interdependently regulated autocrine and/or paracrine systems for cellular growth in HCC. This might be clinically interesting, since new classes of THPOR agonistic/antagonistic drugs may provide novel therapeutic options to correct the frequent hemostatic abnormality seen in HCC patients.

Safety and efficacy of radiofrequency-assisted ALPPS (RALPPS) in patients with cirrhosis-related hepatocellular carcinoma

Background and aims: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has high morbidity and mortality. In this study, the safety and efficacy of a modification of ALPPS (radiofrequency-assisted ALPPS, RALPPS) were assessed in patients with hepatocellular carcinoma (HCC).Materials and methods: Patients who were diagnosed with HCC and were considered to have an insufficient future liver remnant (FLR) were enrolled. In stage I, a radiofrequency ablation (RFA) device was used to cauterise along the planned transection plane to form a coagulum avascular area. When the FLR reached above 40%, hepatectomy was performed in stage II along the coagulum area established previously. After two stages, operative morbidity, mortality, per cent increase in FLR, operative time and blood loss were evaluated.Results: Between July 2014 and September 2015, 10 patients with HCC (9 with hepatitis-related cirrhosis) were treated with the RALPPS procedure. The incidence of severe complications (Clavien-Dindo ≥ IIIb) was 20% (2/10). One patient died. No biliary leakage, intraperitoneal infection or post-hepatectomy liver failure (PHLF) occurred after both stages. The median FLR before stage I was 31% (364 ml). This increased to 47% (632 ml) before stage II after a median interval of 28 days. The median percentage increase in FLR was 53% (210 ml). Additionally, the median operative time during the first and second stages was 214 and 281 min, respectively. The corresponding median blood loss was 200 and 550 ml, respectively.Conclusions: RALPPS has a potential advantage in eliminating serious complications of biliary leakage and PHLF associated with classic ALPPS. On the basis of rigorous patient selection criteria, RALPPS may achieve the same effect of promoting significant growth of the FLR in patients with cirrhosis-related HCC and insufficient FLR volume, albeit at the cost of a longer interval time.

A score model for predicting post-liver transplantation survival in HBV cirrhosis-related hepatocellular carcinoma recipients: a single center 5-year experience

The prognostic prediction of liver transplantation (LT) guides the donor organ allocation. However, there is currently no satisfactory model to predict the recipients' outcome, especially for the patients with HBV cirrhosis-related hepatocellular carcinoma (HCC). The present study was to develop a quantitative assessment model for predicting the post-LT survival in HBV-related HCC patients. Two hundred and thirty-eight LT recipients at the Liver Transplant Center, First Affiliated Hospital, Zhejiang University School of Medicine between 2008 and 2013 were included in this study. Their post-LT prognosis was recorded and multiple risk factors were analyzed using univariate and multivariate analyses in Cox regression. The score model was as follows: 0.114X(Child-Pugh score)-0.002X(positive HBV DNA detection time)+0.647X(number of tumor nodules)+0.055X(max diameter of tumor nodules)+0.231XlnAFP+0.437X(tumor differentiation grade). The receiver operating characteristic curve analysis showed that the area under the curve of the scoring model for predicting the post-LT survival was 0.887. The cut-off value was 1.27, which was associated with a sensitivity of 72.5% and a specificity of 90.7%, respectively. The quantitative score model for predicting post-LT survival proved to be sensitive and specific.

Pleomorphic hepatocellular carcinoma following consumption of hypericum perforatum in alcoholic cirrhosis

Hepatocellular carcinoma (HCC) often develops in patients with underlying liver disease, yet HCC with syncytial giant cells (SGCs) is extremely rare. Herein, we report a 55-year-old man with a 6-year history of alcoholic cirrhosis who during his regular checkup presented with marked elevation of alpha-fetoprotein. Clinical examination and imaging analyses revealed a tumor-like lesion in segment 4 of the liver, which was removed by limited wedge resection. Histological analysis by hematoxylin and eosin staining indicated pleomorphic and atypical nodules, with some SGCs, embedded within the boundaries of the neoplastic lesion. The adjacent liver parenchyma showed microvesicular steatosis, pericellular fibrosis, and moderate hemosiderin accumulation (grade 2, as determined by Prussian blue iron stain) in hepatocytes and Kupffer cells but no copper accumulation (as determined by orcein stain). Immunohistochemical analysis showed hepatocyte antigen-positive staining for the neoplastic cells and SGCs. The diagnosis was made for cirrhosis-related HCC with SGCs. The previous reports of pleomorphic HCC have featured osteoclast-like (i.e., mesenchymal type) giant cells, making this case of epithelial type giant cells very rare. The patient's 6-month history of hypericum perforatum/St John's wort self-medication may have prompted the cirrhosis or HCC progression or the unusual SGC manifestation.

Prognostic Gene Expression Signature for Patients With Hepatitis C–Related Early-Stage Cirrhosis

Cirrhosis affects 1% to 2% of the world population and is the major risk factor for hepatocellular carcinoma (HCC). Hepatitis C cirrhosis-related HCC is the most rapidly increasing cause of cancer death in the United States. Noninvasive methods have been developed to identify patients with asymptomatic early-stage cirrhosis, increasing the burden of HCC surveillance, but biomarkers are needed to identify patients with cirrhosis who are most in need of surveillance. We investigated whether a liver-derived 186-gene signature previously associated with outcomes of patients with HCC is prognostic for patients with newly diagnosed cirrhosis but without HCC. We performed gene expression profile analysis of formalin-fixed needle biopsy specimens from the livers of 216 patients with hepatitis C-related early-stage (Child-Pugh class A) cirrhosis who were prospectively followed up for a median of 10 years at an Italian center. We evaluated whether the 186-gene signature was associated with death, progression of cirrhosis, and development of HCC. Fifty-five (25%), 101 (47%), and 60 (28%) patients were classified as having poor-, intermediate-, and good-prognosis signatures, respectively. In multivariable Cox regression modeling, the poor-prognosis signature was significantly associated with death (P = .004), progression to advanced cirrhosis (P < .001), and development of HCC (P = .009). The 10-year rates of survival were 63%, 74%, and 85% and the annual incidence of HCC was 5.8%, 2.2%, and 1.5% for patients with poor-, intermediate-, and good-prognosis signatures, respectively. A 186-gene signature used to predict outcomes of patients with HCC is also associated with outcomes of patients with hepatitis C-related early-stage cirrhosis. This signature might be used to identify patients with cirrhosis in most need of surveillance and strategies to prevent the development of HCC.

An Intronic Variant in the GRP78, a Stress-Associated Gene, Improves Prediction for Liver Cirrhosis in Persistent HBV Carriers

BackgroundOur previous study indicated that a common variant (rs430397 G>A) in the intron 5 of glucose-regulated protein 78 (GRP78) gene was associated with risk and prognosis of primary hepatocellular carcinoma (HCC), including HBV- and cirrhosis-related HCC. rs430397 polymorphism may be a contributing factor or biomarker of HBV infection or HBV-related cirrhosis.Methodology/Principal Findings539 non-HBV-infected individuals, 205 self-limited infection and 496 persistent HBV infection were recruited between January 2001 and April 2005 from the hospitals in Southern China. Genomic DNA was genotyped for rs430397. The associations between the variation and susceptibility to liver cirrhosis (LC) in persistent HBV infection were examined. We observed that individuals carrying allele rs430397A were more likely to become HBV-related LC. When persistently infected patients were divided into four subgroups, patients with phase IV had an increased allele A and genotype AG compared with phase I and/or phase III. Decreased serum albumin and prolonged plasma prothrombin time (PT) were showed in LC patients carrying genotype AA. Furthermore, rs430397 genotype had an increased susceptibility to LC with dose-dependent manners (P-trend = 0.005), and the genotype did constitute a risk factor for the development of advanced LC (Child–Pugh classification C and B, P-trend = 0.021).Conclusions/Significancers430397 polymorphism may be a contributing factor to LC in persistent HBV carriers.

Regulatory T cells in HBV and HCV liver diseases: implication of regulatory T lymphocytes in the control of immune response

Importance of the field: Hepatic cirrhosis is a frequent consequence of chronic hepatitis infection (HBV and HCV) or alcohol abuse and the most common cause of hepatocellular carcinoma (HCC). Currently, liver transplantation remains the only effective therapeutic approach for cirrhosis-related HCC patients. The evolution of the pathology strongly depends on immunological mechanisms.Areas covered in this review: Despite the presence of specific T cells, viral chronic infection and continuous tumor growth suggest a failure of immune control. It appears that direct suppression of antiviral or antitumor effector cells by regulatory T cells plays a pivotal role in the impairment of immune response. Several types of regulatory T cells have been described, natural regulatory T cells (nTreg) and induced-type 1 regulatory T cells (Tr1) being the best characterized.What the reader will gain: Currently, there is no evidence for a direct implication of regulatory T cells in the evolution of hepatitis, especially concerning chronic infection, cirrhosis late stage and HCC progress. However, recent studies show that regulatory T cells are implicated in the modulation of HBV- and HCV-associated immune response, thus, promoting HCC progress.Take home message: Therefore, nTreg and Tr1 cells seem to play an important role in the control of immune response leading to chronic hepatitis infection and progression of the pathology to cirrhosis and HCC.

Single nucleotide polymorphism of rs430397 in the fifth intron of GRP78 gene and clinical relevance of primary hepatocellular carcinoma in Han Chinese: Risk and prognosis

Large number of data showed that allele variants in certain genes are markers for hepatocellular carcinoma (HCC). GRP78 is a stress-associated protein which is a central regulator of endoplasmic reticulum homeostasis due to its multiple functional roles in the folding, maturation and transport of proteins. A case-control study was conducted on 576 HCC patients, and 539 age- and gender-matched healthy subjects to examine whether rs430397 polymorphism in the fifth intron of GRP78 gene is associated with the development and prognosis of HCC. Polymorphism in rs430397 was analyzed by resequencing and TaqMan real-time PCR. Allele A, genotype AA and combined genotypes (AG+AA) displayed significantly increased risk for HCC (OR = 1.48, 95%CI = 1.07-1.79, p = 0.010; OR = 2.25, 95%CI = 1.08-3.38, p = 0.019; and OR = 1.50, 95%CI = 1.09-1.85, p = 0.012, respectively). Genotypes AA and AG were mainly associated with HBV-related HCC (85.8%; p < 0.00001 versus HBV noncarriers with HCC) and cirrhosis-related HCC (90%; p = 0.011 versus noncirrhosis HCC). Patients carrying the AA genotype had a shorter survival time (median 23.0 months in all cases; median 21.0 months in the cases carrying HBsAg). Like HBV and cirrhosis, the rs430397 is an independent prognostic factor influencing the survival of HCC. In conclusion, allele A and genotypes AA and AG of rs430397 may represent high risk and poor prognosis for HCC.

Transcatheter chemoembolization in the treatment of HCC in patients not eligible for curative treatments: midterm results of doxorubicin-loaded DC bead

To examine the results of segmental transcatheter arterial chemoembolization with doxorubicin-loaded DC Bead in the treatment of hepatocellular carcinoma (HCC) in non-surgical candidates. Seventy-one patients (60% men; 11% women; mean age 63; range 46-71 years) with documented HCC of 3-10 cm in diameter (mean 6.2) were enrolled prospectively in the study. All patients had cirrhosis-related HCC that was developed on an underlying controlled hepatitis infection. Only patients with compensated cirrhosis--Child A or B--were included in this study. Overall complete response (CR) according to EASL on an intention to treat basis was seen in 11 patients who developed complete necrosis (15.5%). Objective response (OR) ranged from 66.2% to 85.5% across the four treatments. Survival at 12 months was 97.05%. Sustained CR was observed in 11 (16.1%), and OR in 49 (72%). Sustained partial response was seen in 49 patients (72.05%). Survival at 18 months was 94.1%. At 24 months follow-up survival was 91.1%. Sustained OR was seen in 45 patients (66.2%) while sustained CR was 16.1% (11/68). At 30 months survival was 88.2%. One patient with CR developed multifocal HCC in areas that most likely were not embolized during the previous embolization sessions. In this patient recurrence-free survival was 28 months. Alpha Fetroprotein levels decreased significantly in measurements 1 month post each procedure (p < 0.001). Bilirubin, gamma-GT, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase (ALP) showed only transient increases observed during the study period. Severe procedure-related complications were seen in 4.2% (cholecystitis: n = 1; liver abscess: n = 1; pleural effusion: n = 1). Post Embolization Syndrome (PES) was observed in all patients. Transcatheter arterial chemoembolization with DC Bead is an effective and safe procedure in the treatment of HCC patients not eligible for curative treatments with high rates of response and high rates of mid term survival.

Hepatocellular cancer: resection or transplantation.

Surgery remains the treatment of choice for hepatocellular carcinoma (HCC). For HCC without underlying cirrhosis resection remains the mainstay treatment option. Prognosis depends on the stage of the tumor. Survival appears to be better for small (less than 5 cm) solitary tumors with negative resection margins and absence of vascular invasion. At present, liver transplantation does not have an established role in the treatment of HCC in a non-cirrhotic liver. Because of the high recurrence rate, it should not be considered for more advanced disease which is not amenable to resection. The surgical approach in cirrhotics depends not only on the stage of the tumor but also on the liver functional reserve. Tumor size, presence of multifocal disease, and vascular invasion determine the risk of HCC recurrence after resection, and the functional stability of the liver determines both resectability and outcome. In societies in which transplantation is not available, small tumors will be treated with liver resection. The outcome in patients with well preserved liver function is relatively good, at least in the medium term. However, recurrent tumor and progressive hepatic decompensation have significant adverse effects on long-term survival. Poor functional reserve may be associated with significant perioperative mortality and lower survival due to progressive liver failure. In our opinion, for small cirrhosis-related HCCs, liver transplantation offers better long-term prospects than resection. Therefore, if liver transplantation is available as an option it should be considered as the treatment of choice, particularly for younger patients with otherwise good life expectancy.
