Differentiating Well-Differentiated from Poorly-Differentiated HCC: The Potential and the Limitation of Gd-EOB-DTPA in the Presence of Liver Cirrhosis. Diagnostics (Basel) 2024; 14:1676. [PMID: 39125552 PMCID: PMC11311873 DOI: 10.3390/diagnostics14151676] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2024] [Revised: 07/30/2024] [Accepted: 07/31/2024] [Indexed: 08/12/2024] Open
Abstract
This study uses magnetic resonance imaging (MRI) to investigate the potential of the hepatospecific contrast agent gadolinium ethoxybenzyl-diethylenetriaminepentaacetic acid (Gd-EOB-DTPA) in distinguishing G1- from G2/G3-differentiated hepatocellular carcinoma (HCC). Our approach involved analyzing the dynamic behavior of the contrast agent in different phases of imaging by signal intensity (SI) and lesion contrast (C), to surrounding liver parenchyma, and comparing it across distinct groups of patients differentiated based on the histopathological grading of their HCC lesions and the presence of liver cirrhosis. Our results highlighted a significant contrast between well- and poorly-differentiated lesions regarding the lesion contrast in the arterial and late arterial phases. Furthermore, the hepatobiliary phase showed limited diagnostic value in cirrhotic liver parenchyma due to altered pharmacokinetics. Ultimately, our findings underscore the potential of Gd-EOB-DTPA-enhanced MRI as a tool for improving preoperative diagnosis and treatment selection for HCC while emphasizing the need for continued research to overcome the diagnostic complexities posed by the disease.

Brusset B, Jacquemin M, Teyssier Y, Roth GS, Sturm N, Roustit M, Bône A, Ghelfi J, Costentin CE, Decaens T. Radiological diagnosis of hepatocellular carcinoma does not preclude biopsy before treatment. JHEP Rep 2024; 6:100957. [PMID: 38234407 PMCID: PMC10792651 DOI: 10.1016/j.jhepr.2023.100957] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 10/16/2023] [Accepted: 10/17/2023] [Indexed: 01/19/2024] Open
Abstract
Background & Aims The diagnosis of hepatocellular carcinoma (HCC) in patients with cirrhosis relies on non-invasive criteria based on international guidelines. The advent of systemic therapies warrants reconsideration of the role of biopsy specimens in the diagnosis of HCC. Accordingly, we investigated the diagnostic performance of the LI-RADS 2018 and the AASLD 2011 criteria. Methods Consecutive patients with cirrhosis who underwent a biopsy for suspected HCC between 2015 and 2020 were included. The available imaging studies (computed tomography and/or magnetic resonance imaging) were blindly reviewed by two independent radiologists. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were assessed for LI-RADS, AASLD, and biopsies. Results In total, 167 patients underwent both available biopsy and imaging. Of the 137 relevant biopsies, 114 patients had HCC (83.2%), 12 (9%) had non-HCC malignant lesions, and 11 (8%) had benign nodules. The PPV and NPV of the biopsies were 100% and 62%, respectively; 30 biopsies were non-contributive. The PPV and NPV of the LI-RADS categories were 89% and 32.8% for LR-5 and 85.5% and 54.5% for LR-4 + 5 + TIV, respectively. The PPV and NPV of the 2011 AASLD criteria were 93.2% and 35.6%, respectively. The interobserver kappa (k = 0.380) for the LR-5 categories was reasonable. Of 100 LR-5 nodules, 11 were misclassified, in particular one case was a colorectal metastasis, and two cases were cholangiocarcinomas, of which nine were identified through biopsy, whereas six were correctly classified according to LI-RADS (LR-M or LR-TIV). Fifty percent of macrotrabecular HCC and 48.4% of poorly differentiated HCC (Edmonson 3 and 4) were not classified as LR-5. Conclusions LI-RADS 2018 did not outperform the AASLD 2011 score as a non-invasive diagnosis of HCC. Tumor biopsy allowed restoration of an accurate diagnosis in 11% of LR-5 cases. A combined radiological and histological diagnosis should be considered mandatory for good treatment assessment. Impact and Implications Although biopsy is not required for hepatocellular carcinoma diagnosis when the LI-RADS criteria are met according to current guidelines, our study underscores the limits of radiology and the need for biopsy when hepatocellular carcinoma is suspected. Histological findings could change therapeutics of liver tumors even if only for a small proportion of patients. Histological proof of the type of cancer is a standard in oncology.

Serum-Exosome-Derived miRNAs Serve as Promising Biomarkers for HCC Diagnosis. Cancers (Basel) 2022; 15:cancers15010205. [PMID: 36612201 PMCID: PMC9818484 DOI: 10.3390/cancers15010205] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 12/23/2022] [Accepted: 12/25/2022] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Serum exosomes are emerging as key liquid biopsy biomarkers for the early diagnosis of cancer. However, the proportion and distribution of small RNA (sRNA) species from serum exosomes of hepatocellular carcinoma (HCC) patients remain unclear. Effective and reliable biomarkers for HCC diagnosis should be explored. METHODS In this study, we aimed to use sRNA sequencing to profile the sRNAs of serum exosomes in HCC and non-tumor donors. The serum exosomes of 124 HCC patients and 46 non-tumor donors were enrolled for detecting the values of the potential biomarkers for the diagnosis of HCC. RESULTS We found that miRNAs accounted for the maximal percentage of all types of sRNAs both in the serum exosomes of HCC patients and non-tumor donors. This indicated that the serum-exosome-derived microRNAs (miRNAs) were the most valuable as potential biomarkers in HCC diagnosis. Then, miRNAs were set as research candidates. In our Chinese cohorts, three serum-exosome-derived miRNAs (miR-122-5p, let-7d-5p, and miR-425-5p) could be promising biomarkers for distinguishing HCC patients from non-tumor donors. In addition, they were preferred for the early diagnosis of HCC. We also presented the base distribution of some novel serum-exosome-derived miRNAs and described the potential values as biomarkers. CONCLUSIONS The results suggested that the serum-exosome-derived miRNAs were the most crucial sRNA species and they highlighted the potential of serum-exosome-derived miRNAs as promising biomarkers for HCC diagnosis.

Abstract
This study aimed to assess the degree of differentiation of hepatocellular carcinoma (HCC) using Gd-EOB-DTPA-assisted magnetic resonance imaging (MRI) with T1 relaxometry. Thirty-three solitary HCC lesions were included in this retrospective study. This study's inclusion criteria were preoperative Gd-EOB-DTPA-assisted MRI of the liver and a histopathological evaluation after hepatic tumor resection. T1 maps of the liver were evaluated to determine the T1 relaxation time and reduction rate between the native phase and hepatobiliary phase (HBP) in liver lesions. These findings were correlated with the histopathologically determined degree of HCC differentiation (G1, well-differentiated; G2, moderately differentiated; G3, poorly differentiated). There was no significant difference between well-differentiated (950.2 ± 140.2 ms) and moderately/poorly differentiated (1009.4 ± 202.0 ms) HCCs in the native T1 maps. After contrast medium administration, a significant difference (p ≤ 0.001) in the mean T1 relaxation time in the HBP was found between well-differentiated (555.4 ± 140.2 ms) and moderately/poorly differentiated (750.9 ± 146.4 ms) HCCs. For well-differentiated HCCs, the reduction rate in the T1 time was significantly higher at 0.40 ± 0.15 than for moderately/poorly differentiated HCCs (0.25 ± 0.07; p = 0.006). In conclusion this study suggests that the uptake of Gd-EOB-DTPA in HCCs is correlated with tumor grade. Thus, Gd-EOB-DTPA-assisted T1 relaxometry can help to further differentiation of HCC.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common and fatal cancer in the world. HCC frequently presents with advanced disease, has a high recurrence rate and limited treatment options, which leads to very poor prognosis. This warrants urgent improvement in the diagnosis and treatment. Liver biopsy plays very important role in the diagnosis and prognosis of HCC, but with technical advancements and progression in the field of imaging, clinical guidelines have restricted the role of biopsy to very limited situations. Biopsy also has its own problems of needle tract seeding of tumor, small risk of complications, technical and sampling errors along with interpretative errors. Despite this, tissue analysis is often required because imaging is not always specific, limited expertise and lack of advanced imaging in many centers and limitations of imaging in the diagnosis of small, mixed and other variant forms of HCC. In addition, biopsy confirmation is often required for clinical trials of new drugs and targeted therapies. Tissue biomarkers along with certain morphological features, phenotypes and immune-phenotypes that serve as important prognostic and outcome predictors and as decisive factors for therapy decisions, add to the continuing role of histopathology. Advancements in cancer biology and development of molecular classification of HCC with clinic pathological correlation, lead to discovery of HCC phenotypic surrogates of prognostic and therapeutically significant molecular signatures. Thus tissue characteristics and morphology based correlates of molecular subtypes provide invaluable information for management and prognosis. This review thus focuses on the importance of histopathology and resurgence of role of biopsy in the diagnosis, management and prognostication of HCC.

Abstract
A correct diagnosis of hepatocellular carcinoma (HCC) in cirrhotic patients with focal liver lesions is one of the most important issues nowadays. Probably one of the oldest debates in the hepatology community is whether to perform liver biopsy (LB) in all cirrhotic patients with focal liver lesions. We now face a time when oncology is moving towards personalized medicine. According to the current European Association for the study of Liver diseases HCC guidelines, LB has only a minor role in the management of HCC. However, the current recommendations were made more than five years ago. As time has passed, the development of high-throughput molecular technologies has helped reveal the main molecular mechanism involved in HCC development and progression. Several subtypes of HCC, with both molecular and histological characterization, have been described. Importantly, some of these subtypes have prognostic impact. In the context of personalized treatment, the role of LB will be carefully reconsidered. Until then, it is mandatory to know the various techniques of LB, their performances, complications and limitations. The balance of risk and benefit defines many of the decisions that we make as providers of medical care. In this review, we discuss not only the risks associated with LB, but also the benefits of biopsy in various clinical scenarios. Not long from now, the role of LB will be reconsidered. It is possible that we will go back in time and once again use biopsy for HCC diagnosis. Then again, we may move back to the future to try to improve the use of liquid biopsy in the follow-up of HCC patients after various treatment modalities.

Abstract
Hepatocellular cancer is one of the most common and fatal cancer tumor worldwide. However, the obtained results are questionable in terms of medical treatment of hepatocellular cancer. The muscle, soft tissue and cutaneous metastases of hepatocellular cancer, for instance, are rare and may result from interventional procedures. Seeding of tumor along the biopsy needle upon percutaneous biopsy is a very rare phenomenon. We report a very rare case of a 79 -year- old man, known to be hepatitis C virus carrier with a metastatic tumor in abdominal wall caused by seeding of tumor after three years following a percutaneous biopsy procedure. Even years later, after a biopsy procedure for diagnostic purposes and may be soft tissue metastases. This complication is a very rare condition that should not be ignored but can be observed. The biopsy requirement should be questioned closely and avoided unnecessary biopsy procedures.

Abstract
Liver transplantation (LT) for hepatocellular carcinoma (HCC) has been established as a standard treatment in selected patients for the last two and a half decades. After initially dismal outcomes, the Milan criteria (MC) (single HCC ≤ 5 cm or up to 3 HCCs ≤ 3 cm) have been adopted worldwide to select HCC patients for LT, however cumulative experience has shown that MC can be too strict. This has led to the development of numerous expanded criteria worldwide. Morphometric expansions on MC as well as various criteria which incorporate biomarkers as surrogates of tumor biology have been described. HCC that presents beyond MC initially can be downstaged with locoregional therapy (LRT). Post-LRT monitoring aims to identify candidates with favorable tumor behavior. Similarly, tumor marker levels as response to LRT has been utilized as surrogate of tumor biology. Molecular signatures of HCC have also been correlated to outcomes; these have yet to be incorporated into HCC-LT selection criteria formally. The ongoing discrepancy between organ demand and supply makes patient selection the most challenging element of organ allocation. Further validation of extended HCC-LT criteria models and pre-LT treatment strategies are required.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) represents an increasing health burden worldwide and a challenging disease both in terms of diagnosis and treatment. METHODS The literature available on PubMed for the period of 1990-2016 was reviewed with reference to liver allocation, HCC, liver transplantation (LT), and prediction, and the allocation rules of the German Transplant Act were reviewed. RESULTS Due to etiological and geographical diversity, HCC is not a homogeneous disease. In the vast majority of patients, HCC develops as a complication of chronic liver disease and cirrhosis. While most patients present with advanced HCC for which palliative strategies are the only available option, LT is the best treatment approach as it not only eliminates the diseased liver and the underlying hepatocarcinogenic mechanisms but also the cancer. The decision for LT is not an easy one to make, because outcome prediction, staging, bridging therapy, and recurrence prevention are difficult and are estimated against the background of the scarce resource of donor organs which are also competitively sought after by patients suffering from non-neoplastic terminal liver diseases, raising the issue of equality of chances in a rationed therapeutic modality. Currently, the Milan criteria are the best evaluated decision tool for LT, but many issues such as down-staging, favorable biological behavior during treatment, expansion of the morphological classification, molecular predictors, and individualized approaches are not yet satisfactorily addressed. CONCLUSION In order to provide a fair and effective approach to LT in HCC, the employed allocation rules require continuous development and scientific evaluation. Recently, the allocation rules for standard exception priority according to the German Transplant Act have been revised to improve patient selection for LT in HCC.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) recurrence remains a key issue after liver transplantation. This study aimed to determine a subgroup of HCC patients within the Milan criteria who could achieve a theoretical goal of zero recurrence rates after liver transplantation. METHODS Between 1999 and 2009, 179 patients who received liver transplantation for HCC within the Milan criteria were retrospectively included. Analysis of the factors associated with HCC recurrence was performed to determine the subgroup of patients at the lowest risk of recurrence. RESULTS Seventy-two percent of the patients received a bridging therapy, including 54 liver resections. Eleven (6.1%) patients recurred within a delay of 19+/-22 months and ultimately died. Factors associated with recurrence were serum alpha-fetoprotein level >400 ng/mL, satellite nodules, poor differentiation, microvascular invasion and cholangiocarcinoma component. Recurrence rates decreased from 6.1% to 3.1% in patients without any of these factors. CONCLUSIONS Among HCC patients within the Milan criteria, selecting patients with factors based on histology would allow tending towards zero recurrence, and prior histological assessment by liver biopsy or resection may be essential to rule out poorly differentiated tumors, microvascular invasion, and cholangiocarcinoma component.

Abstract
Morphological criteria have always been considered the benchmark for selecting hepatocellular carcinoma (HCC) patients for liver transplantation (LT). These criteria, which are often inappropriate to express the tumor’s biological behavior and aggressiveness, offer only a static view of the disease burden and are frequently unable to correctly stratify the tumor recurrence risk after LT. Alpha-fetoprotein (AFP) and its progression as well as AFP-mRNA, AFP-L3%, des-γ-carboxyprothrombin, inflammatory markers and other serological tests appear to be correlated with post-transplant outcomes. Several other markers for patient selection including functional imaging studies such as 18F-FDG-PET imaging, histological evaluation of tumor grade, tissue-specific biomarkers, and molecular signatures have been outlined in the literature. HCC growth rate and response to pre-transplant therapies can further contribute to the transplant evaluation process of HCC patients. While AFP, its progression, and HCC response to pre-transplant therapy have already been used as a part of an integrated prognostic model for selecting patients, the utility of other markers in the transplant setting is still under investigation. This article intends to review the data in the literature concerning predictors that could be included in an integrated LT selection model and to evaluate the importance of biological aggressiveness in the evaluation process of these patients.

Abstract
Hepatocellular carcinoma (HCC) is rapidly becoming one of the most prevalent cancers worldwide. With a rising rate, it is a prominent source of mortality. Patients with advanced fibrosis, predominantly cirrhosis and hepatitis B are predisposed to developing HCC. Individuals with chronic hepatitis B and C infections are most commonly afflicted. Different therapeutic options, including liver resection, transplantation, systemic and local therapy, must be tailored to each patient. Liver transplantation offers leading results to achieve a cure. The Milan criteria is acknowledged as the model to classify the individuals that meet requirements to undergo transplantation. Mean survival remains suboptimal because of long waiting times and limited donor organ resources. Recent debates involve expansion of these criteria to create options for patients with HCC to increase overall survival.

Abstract
The increasing incidence of hepatocellular carcinoma (HCC) has led to the need to identify patients at risk for HCC so that a program of screening can be undertaken. Screening for HCC has led to earlier diagnosis of tumors and thus has aided in initiating optimal medical treatment earlier in the disease course. Advances in radiological techniques and the identification of more accurate serum tests to diagnose HCC continue to be important areas of study and exploration. In particular, there have been efforts to develop new tumor markers to aid in the diagnosis of HCC and guide therapy of tumors.

Preoperative tumour biopsy does not affect the oncologic course of patients with transplantable HCC. J Hepatol 2014; 61:589-93. [PMID: 24818985 DOI: 10.1016/j.jhep.2014.04.046] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2013] [Revised: 04/17/2014] [Accepted: 04/21/2014] [Indexed: 12/13/2022]
Abstract
BACKGROUND & AIMS Preoperative fine-needle aspiration biopsy (PFNAB) allows obtaining reliable hepatocellular carcinoma (HCC) diagnosis before liver transplantation (LT) in doubtful situations, but may result in higher recurrence rates following LT. This study aimed to evaluate whether PFNAB actually jeopardized the outcome of patients with transplantable HCC. METHODS From 2002 to 2012, among 309 HCC patients listed for LT, 80 (26%) underwent PFNAB (PFNAB+). Their characteristics, modalities of recurrence, and survivals were retrospectively compared to those of the 229 (74%) patients without PFNAB (PFNAB-). RESULTS The two groups (PFNAB+ vs. PFNAB-) were similar in terms of demography, rates of lesions within the Milan criteria (81% vs. 79%, p=0.676), and duration on the waiting list (7.0 vs. 6.9 months, p=0.891). Dropout following tumour progression was similar between both groups (6% vs. 11%, p=0.424). Among the 278 (90%) transplanted patients, pathological analysis revealed that 11 (4%) patients had non-HCC lesions including 10 in PFNAB- patients. Median follow-up was 34 months (12-135) and recurrence after LT was observed in 25 (9%) patients with no difference between both groups (9.3% vs. 8.9%, p=0.904). Parietal recurrence was observed in one PFNAB+ patient and in 2 PFNAB- patients after radiofrequency ablation (p=0.797). On an intention to treat basis, 1-, 3-, and 5-year overall survivals (89%, 69%, and 60% vs. 85%, 67%, and 61%, p=0.601) were not significantly different between PFNAB+ and PFNAB- patients. CONCLUSIONS This study supports that preoperative tumour biopsy does not negatively influence the oncologic course of HCC patients eligible for LT. Hence, there is no argument to restrict biopsy in doubtful situations.

Abstract
The current American Association for the Study of Liver Diseases (AASLD) guideline provides strategies for achieving the diagnosis of hepatocellular carcinoma (HCC) based on the size of liver nodules seen on surveillance imaging. For lesions less than 1 cm in size, follow-up surveillance imaging is recommended. Lesions larger than 2 cm require typical radiological hallmark on dynamic imaging. Lesions of 1-2 cm in size require typical imaging features including intense uptake of contrast during arterial phases followed by decreased enhancement during portal venous phases on at least 2 imaging modalities. In cases of atypical radiological features of the suspected lesion, tissue diagnosis either by fine needle aspiration or biopsy should be obtained. Although fine needle aspiration could give a smaller risk of seeding than biopsy, biopsy has been preferred over cytology. Percutaneous biopsy of HCC carries a potential risk of tumor seeding along the needle tract. However the risk is low and there is no clear evidence of post transplant recurrence due to needle tract seeding. Histopathologic assessment can differentiate between premalignant lesions such as dysplastic nodules and early HCC. Atypical variants of HCC can be recognized morphologically which may have associated prognostic value.

Abstract
Hepatocellular carcinoma (HCC) is a serious health problem worldwide because of its association with hepatitis B and C viruses. In this setting, liver transplantation (LT) has become one of the best treatments since it removes both the tumor and the underlying liver disease. Due to the improvement of imaging techniques and surveillance programs, HCC are being detected earlier at a stage at which effective treatment is feasible. The prerequisite for long term success of LT for HCC depends on tumor load and strict selection criteria with regard to the size and number of tumor nodules. The need to obtain the optimal benefit from the limited number of organs available has prompted the maintenance of selection criteria in order to list only those patients with early HCC who have a better long-term outcome after LT. The indications for LT and organ allocation system led to many controversies around the use of LT in HCC patients. This review aims at giving the latest updated developments in LT for HCC focusing on selection criteria, diagnostic tools, prognostic factors, treatment on the waiting list, role of living donor liver transplantation and adjuvant therapy, and the impact of immunosuppression on HCC recurrence after LT.

Abstract
Hepatocellular carcinoma (HCC) represents one of the most common cancers worldwide with rising incidence in developed countries. The best treatment options with curative intent for patients with HCC are liver resection or transplantation, although the role of hepatic ablative therapies has also been recognized. Surgical resection has emerged as the primary treatment in carefully selected patients of HCC. With the advances in surgical and radiological techniques, the perioperative mortality has been reduced to less than 5 % depending on the extent of resection and hepatic reserve. The role of liver transplantation (LT) as the mainstay of treatment for the majority of patients with HCC has evolved in the last few decades. Historically, the Milan criteria have been considered the gold standard for selecting patients; more expanded selection criteria to include those with more advanced tumors have been implemented in recent years. Living donor liver transplantation (LDLT) has emerged as a way to expand the donor pool and has influenced the role of transplantation for HCC, especially in communities with little access to cadaveric transplantation. Salvage transplantation is an alternative option as it allows a window for the biologically less favorable lesions to declare tumor behavior. Salvage transplantation also decreases the burden on transplant resources. Sirolimus, a novel immunosuppressant drug with anti-tumor effect, may have a role in limiting the severity of recurrent disease after transplantation for HCC, and play an important role in the future management of transplant recipients. This article examines the literature on current status of management of HCC.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is an indication for liver resection or transplantation (LT). In most centers, patients whose HCC meets the Milan criteria are considered for LT. The first objective of this study was to analyze whether there is a correlation between the pathologic characteristics of the tumor, survival and recurrence rate. Second, we focused our attention on vascular invasion (VI). METHODS From January 1997 to December 2007, a total of 196 patients who had a preoperative diagnosis of HCC were included. The selection criteria for LT satisfied both the Milan and the San Francisco criteria (UCSF). Demographic, clinical, and pathologic information were recorded. RESULTS HCC was confirmed in 168 patients (85.7%). The median follow-up was 74 months. The pathologic findings showed that 106 patients (54.1%) satisfied the Milan criteria, 134 (68.4%) the UCSF criteria of whom 28 (14.3%) were beyond the Milan criteria but within the UCSF criteria, and 34 (17.3%) beyond the UCSF criteria. VI was detected in 41 patients (24%). The 1-, 3-, and 5-year overall survival rates were 90%, 85%, and 77%, respectively, according to the Milan criteria and 90%, 83%, and 76%, respectively, according to the UCSF criteria (P = NS). In univariate and multivariate analyses, tumor size and VI were significant prognostic factors affecting survival (P < 0.001). Two factors were significantly associated with VI: alfa-fetoprotein level of >400 ng/ml and tumor grade G3. CONCLUSIONS Tumor size and VI were the only significant prognostic factors affecting survival of HCC patients. Primary liver resection could be a potential selection treatment before LT.

Abstract
Liver biopsy with histological examination of liver tissue was for many years the cornerstone of the diagnosis of haemochromatosis, allowing assessment of the degree of iron overload and examination of liver histology for the acute and chronic effects of iron overload. In the past two decades the role of liver biopsy in haemochromatosis has changed dramatically. Liver biopsy is rarely requested for two main reasons: (1) genetic testing for human haemochromatosis (HFE) mutations has proved to be very reliable in the diagnosis of haemochromatosis in Caucasian populations, and (2) the majority of patients with haemochromatosis are now diagnosed at an early stage well before permanent tissue damage occurs, so the need to assess tissue and organ damage has diminished. Liver biopsy continues to have a very important role in a small number of haemochromatosis patients for whom it has both diagnostic and prognostic implications. Liver biopsy is essential for the accurate assessment of patients with non-HFE haemochromatosis and in patients who have dual pathology. It is also useful where there appears to be a discrepancy between HFE genotypes and iron studies, particularly in HFE heterozygotes. Finally, liver biopsy is currently the 'gold standard' for the diagnosis of fibrosis and cirrhosis, although this is changing as non-invasive methods for assessing fibrosis become more reliable and available. Therefore, it is important that pathologists maintain their knowledge and skills in the use of liver biopsy in haemochromatosis and other iron storage disorders.

Abstract
The role of fine needle aspiration (FNA) biopsy of the liver has evolved. Advances in imaging modalities have obviated the need for tissue confirmation in clinically classic hepatocellular carcinoma (HCC). The risks of needle tract seeding and haematogenous dissemination have been actively debated. Nowadays, cytopathologists are confronted by smaller and smaller nodules, detected due to increased surveillance of high-risk cirrhotic patients. Tissue characterization of small well-differentiated hepatocellular nodular lesions (size less than and equal to 2 cm) is extremely challenging and has therapeutic implications. Major issues in the cytodiagnosis of HCC include: (i) distinguishing benign hepatocellular nodular lesions, namely, large regenerative nodules, dysplastic nodules, focal nodular hyperplasia and hepatocellular adenoma from reactive hepatocytes; (ii) distinguishing well-differentiated HCC from benign hepatocellular nodular lesions; (iii) distinguishing poorly differentiated HCC from intrahepatic cholangiocarcinoma and metastatic carcinomas; (iv) determining the histogenesis of a malignant tumour; and (v) determining the site of origin of a malignant tumour. An overview of the biological evolution and histopathological aspects of dysplastic nodules, small HCCs and 'nodule-in-nodule' lesions is presented in tandem with clinically relevant nomenclature. An algorithmic approach to FNA diagnosis of HCC and hepatocellular nodular lesions is outlined. Optimal results depend on (i) a dedicated radiologist-cytopathologist team; (ii) an on-site cytology service, (iii) a combined cytohistological approach, (iv) immunohistochemistry, and (v) clinicopathological correlation. As we move towards personalized medicine, it is envisaged that hepatic FNA is likely to become a point of care in the management protocol as it takes on the additional role of procurement of tumour and peritumoural tissues for genomic and proteomic profiling to enable targeted molecular therapy.

Abstract
The role of hepatic fine-needle aspiration (FNA) biopsy has evolved. Advances in imaging modalities have obviated the need for tissue confirmation in most hepatocellular carcinomas (HCCs). There is risk of needle-tract seeding. Increasingly, small nodules are being detected on ultrasound surveillance of high-risk patients. Diagnostic challenges associated with cirrhosis include distinction of benign hepatocellular nodules, namely, large regenerative nodules and dysplastic nodules, from reactive hepatocytes; and distinction of well-differentiated HCCs from benign hepatocellular nodules. This paper will discuss (i) controversies regarding preoperative/pretransplantation FNA diagnosis of HCC, (ii) update of biological evolution, nomenclature, and histopathologic criteria for diagnosis of precancerous nodules and small HCCs, and (iii) algorithmic approach to FNA diagnosis of hepatocellular nodules. Optimal results depend on dedicated radiologist-cytopathologist team, on-site cytology service; combined cytohistologic approach, immunohistochemistry, and clinicopathologic correlation. Hepatic FNA is likely to be incorporated as a point of care as we move towards personalized medicine.

Abstract
Hepatocellular carcinoma (HCC) is the most frequent malignant tumour of the liver. HCC prognosis is dependent on the determination of the tumour stage by conventional imaging and early screening. However, patient survival can vary with the same tumour stage. Biomarkers thus have a role in providing an earlier diagnosis, better prognosis classification before treatment and classification prognosis during treatment. In this review article, we will provide a successive, detailed description of the serum, pathological, molecular and imaging markers of HCC.

Abstract
Early diagnosis of hepatocellular carcinoma (HCC) has a significant impact on survival by implementation of effective treatment strategies, including hepatic resection, locoregional ablative therapy, and liver transplantation. The use of serum tumor markers and biopsy are particularly important for diagnosis of small hepatic lesions with atypical features on imaging studies. α-Fetoprotein remains the most frequently used tumor marker for the diagnosis of HCC. The development of novel serum biomarkers for HCC, identification of molecular markers for tissue immunohistochemistry, and emergence of new diagnostic techniques such as proteomic profiling may improve the early detection rate of HCC in the future.

Abstract
BACKGROUND & AIMS Knowledge of pre-operative tumour grade is crucial in the management of hepatocellular carcinoma (HCC) because it can influence recurrence and survival after surgery. The accuracy of pre-operative needle core biopsy (NCB) in tumour grading has been assessed in only a few studies with conflicting results. Our aim was to determine the long-term safety and the overall accuracy of NCB in assessing tumour grading in subjects who had undergone liver resection for a single HCC. METHODS Eighty-one cirrhotic patients with HCC who had undergone NCB before liver resection were selected. Only patients with a single HCC and with at least a five-year-follow-up were included. Tumour grading was scored according to a modified Edmondson-Steiner classification: well/moderately (low grade) vs poorly-differentiated (high grade). RESULTS In the 81 patients with a solitary HCC (mean size 4.1 ± 2.3cm) tumour grade was correctly identified by NCB in 74 out of 81 (91.4%) HCCs. NCB overall sensitivity and specificity were 65% and 98.1%, respectively, with a PPV of 92% and an NPV of 91%. No major complications (in particular tumour seeding) were observed. The overall survival rates at 1, 3, and 5 years were 83%, 62%, and 44%, respectively; the recurrence rate after a 5-year-follow-up was 56.2% for low grade and 82.3% for high grade tumours (p<0.007). CONCLUSIONS Pre-operative NCB can be performed on early (<5 cm) HCC cirrhotic patients because it provides histologically useful information for HCC management with good accuracy and a low complication rate.

Abstract
BACKGROUND Despite a growing body of evidence reporting the deleterious mechanical and oncological complications of biopsy of hepatic malignancy, a small but significant number of patients undergo the procedure prior to specialist surgical referral. Biopsy has been shown to result in poorer longterm survival following resection and advances in modern imaging modalities provide equivalent, or better, diagnostic accuracy. METHODS The literature relating to needle-tract seeding of primary and secondary liver cancers was reviewed. MEDLINE, EMBASE and the Cochrane Library were searched for case reports and series relating to the oncological complications of biopsy of liver malignancies. Current non-invasive diagnostic modalities are reviewed and their diagnostic accuracy presented. RESULTS Biopsy of malignant liver lesions has been shown to result in poorer longterm survival following resection and does not confer any diagnostic advantage over a combination of non-invasive imaging techniques and serum tumour markers. CONCLUSIONS Given that chemotherapeutic advances now often permit downstaging and subsequent resection of 'unresectable' disease, the time has come to abandon biopsy of solid lesions outside the setting of a specialist multi-disciplinary team meeting (MDT).

Abstract
Early identification of hepatocellular carcinoma (HCC) is more frequent because of surveillance programs for HCC worldwide. The optimal strategy of surveillance in cirrhosis is a current topical issue. In terms of diagnosis, recent advances in non-invasive imaging technology, including various techniques of harmonic ultrasound, new ultrasound contrast agents, multi-slice helical computed tomography and rapid high quality magnetic resonance, have all improved the accuracy of diagnosis. Consequently the role of liver biopsy in diagnosis of HCC has declined. The imaging diagnosis relies on the hallmark of arterial hypervascularity with portal venous washout. However, with recent advances in genomics and proteomics a great number of potential serum and tissue markers have been identified and are being developed as new candidate markers for both diagnosis and prognosis of hepatocellular carcinoma, and may increase the need for liver biopsy.

Abstract
BACKGROUND Orthotopic liver transplantation (OLT) for patients with cirrhosis and concomitant hepatocellular carcinoma (HCC) in early stages is the treatment of choice, with an acceptable recurrence rate and excellent survival. AIM We sought to evaluate (1) the accuracy of preoperative imaging; (2) the impact of pre-OLT treatments on survival and recurrence; and (3) the influence of beyond Milan criteria selection on global outcomes. METHODS We studied a cohort of 65 patients with HCC among 300 consecutive OLTs over a single 12-year experience. We analyzed the overall outcomes of survival and recurrence, the accuracy of preoperative diagnosis and staging the influence of neoadjuvant treatment prior to OLT, and the effect on overall outcomes beyond the Milan criteria in our series. RESULTS The 65 transplants were performed for HCC, mostly in association with hepatitis C virus and alcoholic cirrhosis with HTP. At a mean follow-up of 40.32 months, the recurrence rate was 5.7% among the 61 HCC confirmed by histopathology. The overall survival was 30.07. Actuarial survivals at 1, 5, and 10 years were 82%, 77%, and 62%, respectively. Six retransplants occurred among the seven graft losses albeit with poor survival after the second graft. Most explants showed low pTNM stages with favorable microscopic features. Preoperative imaging tests failed to achieve an accurate diagnosis in 15.38% of the series. The role of alpha-fetoprotein (AFP) and hepatic biopsy was irrelevant. Unfavorable histopathologic factors predicted a greater recurrence rate, but had no influence on survival. Neither recurrence nor survival were modified by pre-OLT therapy. CONCLUSIONS In our series, AFP, hepatic biopsy, and pre-OLT treatment had limited roles. Radiological imaging techniques underestimated HCC staging and lead to a misdiagnosis to an expected degree. Despite these findings, this single institution experience with OLT for HCC showed excellent survivals with a low recurrence rate including cases of patients beyond the Milan criteria.

Abstract
Early identification of hepatocellular carcinoma (HCC) is crucial to improving the results of therapy and for patients to be eligible for liver transplantation. Recent advances in noninvasive imaging technology include various techniques of harmonic ultrasound, new ultrasound contrast agents, multislice helical computed tomography and rapid high-quality magnetic resonance. The imaging diagnosis relies on the hallmark of arterial hypervascularity with portal venous washout. Since the use of better radiological techniques has improved the accuracy of noninvasive diagnosis, the role of liver biopsy in the diagnosis of HCC has declined. With recent advances in genomics and proteomics, a great number of potential markers have been identified and developed as new candidate markers for HCC. Locoregional therapies currently constitute the best options for early nonsurgical treatment of HCC. Percutaneous ethanol injection shows similar results to resection surgery for single tumors less than 3 cm in diameter. Radiofrequency ablation is superior to percutaneous ethanol injection in terms of local recurrence. Transarterial chemoembolization is currently the most common approach for the management of HCC without curative options since it improves patient survival, but the optimal embolizing agent, length of interval between sessions and whether the chemotherapeutic agent has any effect have not yet been determined. Combining transarterial chemoembolization with antiangiogenic agents, as well as with other techniques, such as radiofrequency ablation, may improve the results. Injection of radioisotopes such as yttrium-90, via the hepatic artery, may be particularly useful in patients with portal vein thrombosis. Comparisons with other transarterial techniques are needed.

Abstract
BACKGROUND Progress in liver imaging has made pretransplantation tumor biopsy no longer systematic in patients with hepatocellular carcinoma (HCC). OBJECTIVES Our aim was to evaluate the accuracy of a preoperative diagnosis of HCC based on clinical and radiological findings in 102 cirrhotics qualified for liver transplantation (LT) between January 1995 and August 2003 at our institution. METHODS The diagnostic accuracy of our policy was assessed by comparing pretransplant diagnosis with the pathologic report of explanted livers. RESULTS Sensitivity, specificity, positive, and negative predictive values for the preoperative clinical and radiological diagnosis of HCC were 89%, 94.3%, 77%, and 93.3%, respectively. A false-positive preoperative diagnosis was made in 20 of 102 patients (19.6%) (dysplastic nodules [n=9], regenerative nodules [n=5] cholangiocellular carcinoma [n=1], hemangioma [n=1], and no lesion [n=4]). All tumors larger than 3 cm were correctly diagnosed, irrespective of serum alpha-fetoprotein (sAFP) levels. The risk of overestimating the diagnosis of HCC in the subgroup of patients with tumors less than 3 cm was conversely correlated with preliver transplantation sAFP (sAFP<or=100 ng/L: 28%; sAFP>100: 11%; sAFP>200: 0%). CONCLUSION In cirrhotics with nodules larger than 3 cm irrespective of sAFP or nodules less than 3 cm with sAFP greater than 200 ng/L, the pretransplant diagnosis of HCC can be made without performing biopsy. In other cases (i.e., nodules less than 3 cm and sAFP lower than 200 ng/L), histologic confirmation of HCC or a close follow-up imaging should be considered.

Abstract
Liver resection (LR) and transplantation offer the only potential chance of cure for patients with hepatocellular carcinoma (HCC). Historically, all patients were treated by hepatic resection. With the advent of liver transplantation (LT) patients with HCC were preferentially placed on the waiting list for LT. However, early experience with LT was associated with a high rate of tumour recurrence and poor long-term survival. The increasing scarcity of donor livers resulted in restrictions being placed on tumour size, and an improvement in patient survival. To date there have been no randomised clinical trials comparing LR to LT. We review the evidence supporting LR and/or LT for HCC and discuss the role of neoadjuvant therapy. The decision of whether to resect or transplant remains debatable and is often determined by centre experience, availability of LT and donor organs.
