Liver cancer is one of the main malignant tumors in the digestive system.Early detection and treatment have positive significance in improving patient prognosis and reducing mortality.MRI is the main method for liver cancer examination,which mainly uses computers to compare imaging of different energy regions of tumors,observe the density and signal changes of liver cancer,and the degree of tumor enhancement.In particular,various new MRI functional imaging technologies,such as diffusion-weighted imaging,perfusion weighted imaging,delayed imaging,liver cell specific contrast agent enhanced imaging,etc.,can be used at the molecular level Multiple aspects such as cell function provide clinicians with richer diagnostic information.Therefore,further comparative analysis of MRI manifestations and pathological results of liver cancer can help to gain a deeper understanding of the biological behavior of tumors and provide a basis for treatment decision-making and prognosis evaluation. 展开更多

Background:The natural history of chronic HBV infection is typically characterized by four stages:the immune tolerance period,the immune clearance period,the immune control period,and the immune escape period.These stages are associated with the distribution of HBcAg in liver cells;however,this relationship remains a topic of broad debate within the field of liver disease.To objectively and quantitatively measure the intracellular distribution of HBcAg,this paper aims to design a method referred to as the“layered evaluation method”and to examine its validation.Methods:The distribution of HBcAg in liver cells is assessed using Image Pro Plus image processing software,along with calculations of cytoplasmic and nuclear positive staining rates.Results:The findings indicate that the highest proportion of patients exhibited a positive cytoplasmic expression rate ranging from 0-2.5%.More than 40% of the total sample was categorized within the 0-2.5% positive nuclear expression range.The HBcAg cytoplasmic positive staining rates were classified into five levels:a cytoplasmic HBcAg positive staining rate of less than 0.05% is designated as level 0,indicating negative expression;a staining rate between 0.05% and 5% is classified as level 1;a rate from 5% to less than 10% is classified as level 2;a rate from 10% to less than 20% is classified as level 3;and a nuclear positivity rate exceeding 20% is classified as level 4.Conclusion:The inflammatory activity grade in these patients was positively correlated with the cytoplasmic distribution of HBcAg.Furthermore,the nuclear distribution rate of HBcAg was significantly higher in the G3 group compared to the other groups. 展开更多

The liver has a central role in metabolism,therefore,it is susceptible to harmful effects of ingested medications(drugs,herbs,and nutritional supplements).Druginduced liver injury(DILI)comprises a range of unexpected reactions that occur after exposure to various classes of medication.Even though most cases consist of mild,temporary elevations in liver enzyme markers,DILI can also manifest as acute liver failure in some patients and can be associated with mortality.Herein,we briefly review available data on DILI induced by targeted anticancer agents in managing classical myeloproliferative neoplasms:Chronic myeloid leukemia,polycythemia vera,essential thrombocythemia,and myelofibrosis. 展开更多

AIM To study the clinicopathological characteristics of neuroendocrine neoplasms(NEN) on liver samples and apply World Health Organization(WHO) 2010 grading of gastroenteropancreatic(GEP) NEN.METHODS Clinicopathological features of 79 cases of NEN of the liver diagnosed between January 2011 to December 2015 were analyzed. WHO 2010 classification of GEP NEN was applied and the tumors were graded as G1, G2 or G3. Two more categories, D1/2(discordant 1/2) and D2/3(discordant 2/3) were also applied. The D1/2 grade tumors had a mitotic count of G1 and Ki-67 index of G2. The D2/3 tumors had a mitotic count of G2 and Ki-67 index of G3. The follow up details which were available till the end of the study period(December 2015) were collected.RESULTS Of the 79 tumors, 16 each were G1 and G2, and 18 were G3 tumors. Of the remaining 29 tumors, 13 were assigned to D1/2 and 16 were D2/3 grade. Male preponderance was noted in all tumors except for G2 neoplasms, which showed a slight female predilection. The median age at presentation was 47 years(range 10-82 years). The most common presentation was abdominal pain(81%). Pancreas(49%) was the most common site of primary followed by gastrointestinal tract(24.4%) and lungs(18%). Radiologically, 87% of the patients had multiple liver lesions. Histopathologically, necrosis was seen in only D2/3 and G3 tumors. Microvascular invasion was seen in all grades. Metastasis occurred in all grades of primary NEN and the grades of the metastatic tumors and their corresponding primary tumors were similar in 67% of the cases. Of the 79 patients, 36 had at least one follow up visit with a median duration of follow up of 8.5 mo(range: 1-50 mo). This study did not show any impact of the grade of tumor on the short term clinical outcome of these patients.CONCLUSION Liver biopsy is an important tool for clinicopathological characterization and grading of NEN, especially when the primary is not identified. Eighty-seven percent of the patients had multifocal liver lesions irrespective of the WHO grade, indicating a higher stage of disease at presentation. Follow up duration was inadequate to derive any meaningful conclusion on long term outcome in our study patients. 展开更多

Since the first description of intraductal papillary mucinous neoplasms(IPMNs)of the pancreas in the eighties,their identification has dramatically increased in the last decades,hand to hand with the improvements in diagnostic imaging and sampling techniques for the study of pancreatic diseases.However,the heterogeneity of IPMNs and their malignant potential make difficult the management of these lesions.The objective of this review is to identify the molecular characteristics of IPMNs in order to recognize potential markers for the discrimination of more aggressive IPMNs requiring surgical resection from benign IPMNs that could be observed.We briefly summarize recent research findings on the genetics and epigenetics of intraductal papillary mucinous neoplasms,identifying some genes,molecular mechanisms and cellular signaling pathways correlated to the pathogenesis of IPMNs and their progression to malignancy.The knowledge of molecular biology of IPMNs has impressively developed over the last few years.A great amount of genes functioning as oncogenes or tumor suppressor genes have been identified,in pancreatic juice or in blood or in the samples from the pancreatic resections,but further researches are required to use these informations for clinical intent,in order to better define the natural history of these diseases and to improve their management. 展开更多

De novo neoplasms account for almost 30% of deaths 10 years after liver transplantation and are the most common cause of mortality in patients surviving at least 1 year after transplant. The risk of malignancy is two to four times higher in transplant recipients than in an age- and sex-matched population, and cancer is expected to surpass cardiovascular complications as the primary cause of death in transplanted patients within the next 2 decades. Since exposure to immunosuppression is associated with an increased frequency of developing neoplasm, long-term immunosuppression should be therefore minimized. Promising results in the prevention of hepatocellular carcinoma(HCC) recurrence have been reported with the use of m TOR inhibitors including everolimus and sirolimus and the ongoing open-label prospective randomized controlled SILVER. Study will provide more information on whether sirolimus-containing vs m TOR-inhibitorfree immunosuppression is more efficacious in reducing HCC recurrence. 展开更多

Liver biopsy evaluation plays a critical role in management of patients with viral hepatitis C. In patients with acute viral hepatitis, a liver biopsy, though uncommonly performed, helps to rule out other nonviral causes of deranged liver function. In chronic viral hepatitis C, it is considered the gold standard in assessment of the degree of necroinflammation and the stage of fibrosis, to help guide treatment and determine prognosis. It also helps rule out any concomitant diseases such as steatohepatitis, hemochromatosis or others. In patients with chronic progressive liver disease with cirrhosis and dominant nodules, a targeted liver biopsy is helpful in differentiating a regenerative nodule from dysplastic nodule or hepatocellular carcinoma. In the setting of transplantation, the liver biopsy helps distinguish recurrent hepatitis C from acute rejection and also is invaluable in the diagnosis of fibrosing cholestatic hepatitis, a rare variant of recurrent hepatitis C. This comprehensive review discusses the entire spectrum of pathologic findings in the course of hepatitis C infection. 展开更多

Intrahepatic cholangiocarcinoma(iCCA)is a rare biliary tract cancer with high mortality rate.Complete resection of the iCCA lesion is the first choice of treatment,with good prognosis after margin-negative resection.Unfortunately,only 12%-40% of patients are eligible for resection at presentation due to cirrhosis,portal hypertension,or large tumor size.Liver transplantation(LT)offers margin-negative iCCA extirpation for patients with unresectable tumors.Initially,iCCA was a contraindication for LT until size-based selection criteria were introduced to identify patients with satisfied post-LT outcomes.Recent studies have shown that tumor biology-based selection can yield high post-LT survival in patients with locally advanced iCCA.Another selection criterion is the tumor response to neoadjuvant therapy.Patients with response to neoadjuvant therapy have better outcomes after LT compared with those without tumor response to neoadjuvant therapy.Another index that helps predict the treatment outcome is the biomarker.Improved survival outcomes have also opened the door for living donor LT for iCCA.Patients undergoing LT for iCCA now have statistically similar survival rates as patients undergoing resection.The combination of surgery and locoregional and systemic therapies improves the prognosis of iCCA patients. 展开更多

Background: Lysine is used widely in livestock production due to the shortage of feed protein resources.Llysine·H2SO4 contains L-lysine sulphate as well as fermentation co-products which contain other amino acids and phosphorus.However,there are few articles about L-lysine·H2SO4 product regarding intestinal morphology and liver pathology of broiler chickens.In this article,we focus on the absorption and metabolism of L-lysine·H2SO4 revealed in the variation of intestinal morphology and liver pathology to determine the tolerance of chicks for L-lysine·H2SO4.Methods: To evaluate the tolerance of broilers for L-lysine·H2SO4,240 one day old broilers were allocated randomly to one of five dietary treatments which included corn-soybean diets containing 0,1%,4%,7% or 10% L-lysine·H2SO4(L-lysine content = 55%).Results: Supplementation of 1% L-lysine·H2SO4 in the diet had no negative effects.However,4%,7% or 10% Llysine·H2SO4 supplementation produced negative responses on broiler performance,carcass characteristics,blood biochemistry,and particularly on intestinal morphology and liver pathology compared with broilers fed the control diet.Conclusion: Our results show that supplementation with 1% L-lysine·H2SO4 had no negative effects on performance,carcass characteristics,blood biochemistry,intestinal morphology and liver pathology in broilers,but supplementation with 4%,7% or 10% L-lysine·H2SO4 produced a negative response,particularly with respect to intestinal morphology and liver pathology. 展开更多

Background:Perihilar cholangiocarcinoma(phCCC)is a dismal malignancy.There is no consensus regard-ing the best treatment for patients with unresectable phCCC.The present review aimed to gather the current pieces of evidence for liver transplantation and liver resection as a treatment for phCCC and to build better guidance for clinical practice.Data sources:The search was conducted in PubMed,Embase,Cochrane,and LILACS.The related references were searched manually.Inclusion criteria were:reports in English or Portuguese literature that a)patients with confirmed diagnosis of phCCC;b)patients treated with a curative intent;c)patients with the outcomes of liver resection and liver transplantation.Case reports,reviews,letters,editorials,conference abstracts and papers with full-text unavailability were excluded from the analysis.Results:Most of the current literature is based on observational retrospective studies with low grades of evidence.Liver resection has better long-term outcomes than systemic chemotherapy or palliation ther-apy and liver transplantation is a good alternative for selected patients with unresectable phCCC.All candidates for resection or transplantation should be medically fit and free of intrahepatic or extrahep-atic diseases.As a general rule,patients presenting with a tumor having a longitudinal size>3 cm or extending below the cystic duct,lymph node disease,confirmed extrahepatic dissemination;intraoper-atively diagnosed metastatic disease;a history of other malignancies within the last five years,and did not complete chemoradiation regimen and were medically unfit should not be considered for transplan-tation.Some of these criteria should be individually assessed.Liver transplantation or resection should only be considered in highly experienced hepatobiliary centers,and any decision-making must be based on a multidisciplinary evaluation.Conclusions:phCCC is a complex condition with high morbidity.Surgical therapies,including hepatec-tomy and liver transplantation,are the best option for better long-term disease-free survival. 展开更多

The purpose of this study was to determine the efficacy of using an ultrasound contrast agent(levovist)to enhance the color Doppler imaging of liver neoplasms.Thirty patients with hepatic tumors were enrolled in this study.After intravenous administration of levovist,the color Doppler signals of normal hepatic vessels were enhanced.In various hepatic tumors,the different patterns of tumor vascularity were observed,which had not been demonstrated in conventional non contrast color Doppler imaging.In 11 of 16 patients with hepatocarcinoma,additional color Doppler signals were observed in the central part of the tumors.On the contrary,3 patients with metastatic liver lesions the enhanced color Doppler signals appear only at the peripheral of tumors.A typical rim like color enhancement was seen in 2 of the 3 cases.In six patients with hepatic hemangiomas contrast enhanced color Doppler imaging demonstrated the blood vessels at the margin of the neoplasms.Contrast enhanced color Doppler imaging improves the visualization of the hepatic neoplasm vascularity.This technique holds great promise for detecting small liver tumors and differentiating hepatic neoplasms. 展开更多

The study examined the association between calcified liver metastases and the histopathology of the primary colorectal carcinoma in Chinese.The clinical,pathological and CT data were retrospectively analyzed in 210 patients (mean age:54.2 years) with liver metastases from colorectal carcinoma.Plain CT scanning and contrast-enhanced scanning were performed in all the patients.For the contrast-enhanced examination,iohexol was injected by using a high pressure syringe at a flow rate of 2.5-3.0 mL/s.The arterial phase lasted approximately 25 s and the portal venous phase about 60 s.All patients had no history of chronic liver diseases and had never received interventional treatments.χ 2-test was used to analyze the rate of calcification in the liver metastasis from colorectal cancer of different differentiation degrees.Among the 210 cases of liver metastases,22 patients (10.5%) were found to have calcified liver metastases on CT scan.Two patients with calcified liver metastasis received lumpectomy and developed calcification in recurrent tumors.Another two patients had calcification in newly developed tumor masses.And the calcification in the newly developed masses was similar to that of their primary counterparts in terms of morphology and distribution.On the enhanced CT scan,the tumors exhibited no enhancement during hepatic arterial phase and showed slight rim enhancement during portal venous scan in the 22 cases.The calcification became obscure on contrast-enhanced scans.Histopathologically,the primary tumors were well-differentiated adenocarcinoma in 6 cases,moderately-differentiated adenocarcinoma in 10,poorly-differentiated adenocarcinoma in 4 and mucinous adenocarcinoma in 2 among the 22 cases.No statistical correlation was noted between the incidence of calcified liver metastasis and the pathological subtypes and differentiation degrees of the primary colorectal carcinoma.It was concluded that calcified liver metastases may result from colorectal adenocarcinomata of different differentiation degrees or mucinous adenocarcinomata in Chinese population.There is no correlation between calcification of liver metastases and the pathological subtype of the primary colorectal carcinoma in Chinese,which is different from the findings that calcified metastases were associated with colorectal mucinous adenocarcinoma in other ethnic groups. 展开更多

Methods: 59 patients with different liver diseases were examined by two-phase or multi-phase dynamic helical CT. Results: Small hepatocellular carcinoma showed a higher density in the arterial phase, and a lower den- sity in the portal vein phase. Large hepatic carcino- ma showed a mixed pattern of higher-density in the arterial phase, and a lower density in the portal vein phase. Metastasis carcinoma showed an 'oxeye sign' in the portal vein phase. Hemangioma was not obvi- ously enhanced in the early arterial phase, marginal- ly enhanced in the arterial phase, and equally-densed in the balanced phase. Conclusion: Two-phase helical CT is of value in im- proving the detection rate of or determining the fea- tures of hepatic diseases by two-phase helical dyna- mic scan (2.0-3.0 ml/s speed, and delay time 25- 30 s and 70-85 s). 展开更多

Aggressive cytoreduction can prolong survival in patients with unresectable liver metastases(LM)from neuroendocrine neoplasms(NEN),and minimally invasive,liver-directed therapies are gaining increasing interest.Catheter-based treatments are used in disseminated disease,whereas ablation techniques are usually indicated when the number of LM is limited.Although radiofrequency ablation(RFA)is by far the most used ablative technique,the goal of this opinion review is to explore the potential role of laser ablation(LA)in the treatment of LM from NEN.LA uses thinner needles than RFA,and this is an advantage when the tumors are in at-risk locations.Moreover,the multi-fiber technique enables the use of one to four laser fibers at once,and each fiber provides an almost spherical thermal lesion of 12-15 mm in diameter.Such a characteristic enables to tailor the size of each thermal lesion to the size of each tumor,sparing the liver parenchyma more than any other liver-directed therapy,and allowing for repeated treatments with low risk of liver failure.A recent retrospective study reporting the largest series of LM treated with LA documents both safety and effectiveness of LA,that can play a useful role in the multimodality approach to LM from NEN. 展开更多

The BCR/ABL fusion gene or the Ph^1-chromosome in the t(9;22)(q34;q11)exerts a high tyrokinase acticity,which is the cause of chronic myeloid leukemia(CML).The1990 Hannover Bone Marrow Classification separated CML from the myeloproliferative disorders essential thrombocythemia(ET),polycythemia vera(PV)and chronic megakaryocytic granulocytic myeloproliferation(CMGM).The 2006-2008 European Clinical Molecular and Pathological(ECMP)criteria discovered 3variants of thrombocythemia:ET with features of PV(prodromal PV),"true"ET and ET associated with CMGM.The 2008 World Health Organization(WHO)-ECMP and 2014 WHO-CMP classifications defined three phenotypes of JAK2^(V617F)mutated ET:normocellular ET(WHO-ET),hypercelluar ET due to increased erythropoiesis(prodromal PV)and ET with hypercellular megakaryocytic-granulocytic myeloproliferation.The JAK2^(V617F)mutation load in heterozygous WHO-ET is low and associated with normal life expectance.The hetero/homozygous JAK2^(V617F)mutation load in PV and myelofibrosis is related to myeloproliferative neoplasm(MPN)disease burden in terms of symptomaticsplenomegaly,constitutional symptoms,bone marrow hypercellularity and myelofibrosis.JAK2 exon 12mutated MPN presents as idiopathic eryhrocythemia and early stage PV.According to 2014 WHO-CMP criteria JAK2 wild type MPL^(515)mutated ET is the second distinct thrombocythemia featured by clustered giant megakaryocytes with hyperlobulated stag-horn-like nuclei,in a normocellular bone marrow consistent with the diagnosis of"true"ET.JAK2/MPL wild type,calreticulin mutated hypercellular ET appears to be the third distinct thrombocythemia characterized by clustered larged immature dysmorphic megakaryocytes and bulky(bulbous)hyperchromatic nuclei consistent with CMGM or primary megakaryocytic granulocytic myeloproliferation. 展开更多

The Polycythemia Vera Study Group(PVSG),World Health Organization(WHO) and European Clinical,Molecular and Pathological(ECMP) classifications agree upon the diagnostic criteria for polycythemia vera(PV) and advanced primary myelofibrosis(MF). Essential thrombocythemia(ET) according to PVSG and 2007/2008 WHO criteria comprises three variants of JAK2V617 F mutated ET when the ECMP criteria are applied. These include normocellular ET,hypercellular ET with features of early PV(prodromal PV),and hypercellular ET due to megakaryocytic,granulocytic myeloprolifera-tion(ET.MGM). Evolution of prodromal PV into overt PV is common. Development of MF is rare in normocellular ET(WHO-ET) but rather common in hypercellular ET.MGM. The JAK2V617 F mutation burden in heterozygous mutated normocellular ET and in heterozygous/homozygous or homozygous mutated PV and ET.MGM is of major prognostic significance. JAK2/MPL wild type ET associated with prefibrotic primary megakaryocytic and granulocytic myeloproliferation(PMGM) is characterized by densely clustered immature dysmorphic megakaryocytes with bulky(bulbous) hyperchromatic nuclei,which are never seen in JAK2V617 F mutated ET,and PV and also not in MPL515 mutated normocellular ET(WHO-ET). JAK2V617 mutation burden,spleen size,LDH,circulating CD34+ cells,and pre-treatment bone marrow histopathology are mandatory to stage the myeloproliferative neoplasms ET,PV,PMGM for proper prognosis assessment and therapeutic implications. MF itself is not a disease because reticulin fibrosis and reticulin/collagen fibrosis are secondary responses of activated polyclonal fibroblasts to cytokines released from the clonal myeloproliferative granulocytic and megakaryocytic progenitor cells in ET.MGM,PV and PMGM. 展开更多

BACKGROUND Amyloidosis is a rare disorder that can be classified into various types,and the most common type is the systemic light chain type.The prognosis of this disease is extremely poor.In general,amyloidosis mainly affects the kidneys and heart and manifests as abnormal proliferation of clonal plasma cells.Cases in which the liver is the primary organ affected by amyloidosis,as in this report,are less common in clinical practice.CASE SUMMARY A 62-year-old man was admitted with persistent liver dysfunction of unknown cause and poor treatment outcomes.His condition persisted,and he developed chronic liver failure,with severe cholestasis in the later stage that was gradually accompanied by renal injury.Ultimately,he was diagnosed with hepatic amyloidosis through liver biopsy and pathological examination.CONCLUSION Hepatic amyloidosis rarely occurs in the clinic,and liver biopsy and pathological examination can assist in the accurate and effective diagnosis of this condition. 展开更多

AIM To determine the prevalence,characteristics and clinical course of pancreatic cystic neoplasms(PCNs) in liver transplantation(LT) recipients.METHODS We retrospectively studied consecutive patients who underwent LT between January 1998 to April 2016. Clinical and laboratory data were obtained from patient medical records. Imaging findings on computed tomography and magnetic resonance cholangiopancreatography were reviewed by two radiologists.RESULTS During the study period,872 patients underwent cadaveric LT. Pancreatic cysts were identified in 53/872(6.1%) and 31/53(58.5%) were PCNs [28 intraductal papillary mucinous neoplasm(IPMN),2 mucinous cystic neoplasm(MCN),1 serous cystadenoma]. Patients with PCNs exhibited less male predominance(55% vs 73%,P = 0.03) compared to patients without pancreatic cysts. Thirteen patients(42%) were diagnosed with PCN pre-LT while 18 patients(58%) developed PCN post-LT. The median size of PCNs was 13 mm [interquartile range(IQR) 10-20 mm]. All IPMNs were side-branch type. Most PCNs were found in the head and body of pancreas(37% each),followed by the tail(25%). Five patients underwent further evaluation with endoscopic ultrasound. Progress imaging was performed on 81% of patients. PCNs remained stable in size and number in all but 2 patients. During a median follow up of 39 mo(IQR 26-58 mo),the 2(6%) patients with MCN underwent pancreatectomy. No PCN patient developed pancreatic adenocarcinoma,while 5 died from illnesses unrelated to the PCN. Among patients without PCN,1/841(0.1%) developed pancreatic adenocarcinoma.CONCLUSION The prevalence of PCNs in LT recipients was similar to the general population(3.6%,31/872). Side-branch IPMNs do not appear to have accelerated malignant potential in post-LT patients,indicating the current surveillance guidelines are applicable to this group. 展开更多
