Pediatr Radiol 2024:10.1007/s00247-024-05958-w. [PMID: 38831055 DOI: 10.1007/s00247-024-05958-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 05/15/2024] [Accepted: 05/16/2024] [Indexed: 06/05/2024]
Abstract
BACKGROUND Multiple differentials exist for pediatric liver tumors under 2 years. Accurate imaging diagnosis may obviate the need for tissue sampling in most cases. OBJECTIVE To evaluate the imaging features and diagnostic accuracy of computed tomography (CT) in liver tumors in children under 2 years. METHODS Eighty-eight children under 2 years with treatment naive liver neoplasms and baseline contrast-enhanced CT were included in this institutional review board approved retrospective study. Two blinded onco-radiologists assessed these tumors in consensus. Findings assessed included enhancement pattern, lobulated appearance, cystic change, calcifications, central scar-like appearance, and metastases. The radiologists classified the lesion as hepatoblastoma, infantile hemangioma, mesenchymal hamartoma, rhabdoid tumor, or indeterminate, first based purely on imaging and then after alpha-fetoprotein (AFP) correlation. Multivariate analysis and methods of comparing means and frequencies were used for statistical analysis wherever applicable. Diagnostic accuracy, sensitivity, and positive predictive values were analyzed. RESULTS The mean age of the sample was 11.4 months (95% CI, 10.9-11.8) with 50/88 (57%) boys. The study included 72 hepatoblastomas, 6 hemangiomas, 4 mesenchymal hamartomas, and 6 rhabdoid tumors. Presence of calcifications, multilobular pattern of arterial enhancement, lobulated morphology, and central scar-like appearance was significantly associated with hepatoblastomas (P-value < 0.05). Fourteen out of eighty-eight lesions were called indeterminate based on imaging alone; six lesions remained indeterminate after AFP correlation. Pure radiology-based diagnostic accuracy was 81.8% (95% CI, 72.2-89.2%), which increased to 92.1% (95% CI, 84.3-96.7%) (P-value > 0.05) after AFP correlation, with one hepatoblastoma misdiagnosed as a rhabdoid tumor. If indeterminate lesions were excluded for biopsy, the accuracy would be 98.8% (95% CI, 93.4-99.9%). CONCLUSION CT had high accuracy for diagnosing liver neoplasms in the under 2-year age population after AFP correlation. Certain imaging features were significantly associated with the diagnosis of hepatoblastoma. A policy of biopsying only indeterminate lesions after CT and AFP correlation would avoid sampling in the majority of patients.

Abstract
Malignant focal liver lesions (FLLs) represent various kinds of epithelial and mesenchymal tumors. In pediatric patients, the understanding of pediatric liver diseases and associated imaging manifestations is essential for making accurate diagnosis and differential diagnosis. This paper will discuss the latest knowledge of the common pediatric malignant FLLs, including undifferentiated embryonal sarcoma, rhabdomyosarcoma, epithelioid hemangioendothelioma, angiosarcoma, and malignant rhabdoid tumor. Medical imaging features are not only helpful for clinical diagnosis, but can also be useful in the evaluation and follow-up of pre- and post-treatment. The future perspectives of contrast-enhanced ultrasound (CEUS) enhancement patterns of FLLs in pediatric patients are also mentioned.

Outcomes of Primary Tumor Excision do not Differ from Non-Resection Methods in Pediatric Mesenchymal Hamartoma of the Liver: A Rapid Systematic Review. J Pediatr Surg 2023; 58:2356-2361.

Abstract
BACKGROUND To conduct a rapid systematic review comparing the outcomes of primary tumor resection versus non-resection on patients with hepatic mesenchymal hamartoma. METHODS We searched the Ovid MEDLINE, EMBASE, Scopus, PubMed, Web of Science, and Google Scholar databases from January 1, 2000 to March 31, 2022. Studies that described cases of hepatic mesenchymal hamartoma, including management and outcomes, were included. RESULTS 62 articles met inclusion criteria with 95 cases in total. Patients were assigned to the primary tumor resection (n = 85) or non-resection (n = 10) cohort based on the described management. Similar rates of morbidity (17% vs 20%) and mortality (6 vs 10%) were identified between cohorts. There were no differences in sex, liver lobe involvement, or tumor size among study groups. CONCLUSIONS Complete tumor resection should remain the gold standard for hepatic mesenchymal hamartomas when an adequate liver remnant exists. Reports of non-resected tumors demonstrating spontaneous regression or stability with watchful waiting have poor long term follow-up and have inadequate evidence of a true mesenchymal hamartoma diagnosis.

Abstract
Mesenchymal hamartoma (MH) is a benign liver tumor accounting for 3% to 8% of all liver tumors in children, commonly manifesting before 3 years of life. Distinguishing MH from hepatoblastoma and other liver tumors relies on imaging and alpha-fetoprotein (which is usually within normal range in MH), before histologic examination. We report a case of a hepatic MH associated with elevated alpha-fetoprotein, leading to a misdiagnosis of hepatoblastoma and the administration of chemotherapy. We draw the attention to the diagnostic difficulty and pitfalls related to alpha-fetoprotein elevation in the setting of a liver tumor, and we highlight the importance of imaging and histology in establishing the diagnosis.

Abstract
Benign solid liver tumors are frequently discovered during routine sonographic examinations. As a rule, malignant tumors can be excluded using contrast medium-based sectional imaging; however, unclear cases can represent a diagnostic challenge. The category of solid benign liver tumors includes first and foremost hepatocellular adenoma (HCA), focal nodular hyperplasia (FNH) and hemangioma. Based on the most recent data, an overview of the current standards in the diagnostics and treatment is given.

Abstract
Background Hepatoblastoma (HB) is the most common primary malignant liver tumor in children. The prognosis of HB metastasis is poor, despite the increasing diversity of treatment. Piezo, a ubiquitously expressed membrane mechano-transduction protein, is involved in the process of tumor cell migration. Under the gene expression profiling interactive analysis (GEPIA) database, Piezo1 was highly expressed in HB and negatively correlated with the overall survival time. Methods Firstly, the expression of Piezo1 in both paracancerous and HB tissues (n = 7) was detected, and the prognostic value of Piezo1 was assessed in HB (n = 160) patients. Secondly, the inhibition and overexpression of Piezo1were executed in two HB cell lines, HepG2 and Huh 6. Methyl thiazolyl tetrazolium (MTT), wound healing and trans-well assays were performed to identify the effect of Piezo1 on the proliferation and metastasis of HB cells, respectively. In addition, a co-immunoprecipitation assay was performed to determine whether Piezo1 has an interaction with HIF-1α. Finally, the expressions level of Piezo1, HIF-1α, and VEGF by overexpression/inhibition each other were detected by RT-qPCR and western blots to find a possible signaling channel in HB metastasis. Results We found that Piezo1 was highly expressed in HB tissues and associated with poor prognosis of patients. Piezo1 was related to cell proliferation in HepG2 and Huh 6 cells. We also found that Piezo1 stimulated HIF-1α expression. Meanwhile, overexpression of Piezo1 promoted the migration and invasion of HB cells, while the promotion was not detected when HIF-1α was suppressed. Additionally, the silencing of HIF-1α inhibited the expression of VEGF, but showed no effect on Piezo1 expression. Conclusion In this study, we identified that Piezo1 was involved in HB metastasis, and the Piezo1-HIF-1α-VEGF axis could be a possible signaling pathway in HB metastasis.

Abstract
INTRODUCTION Up to a third of children undergoing partial hepatectomy for primary hepatic malignancies experience at least one perioperative complication, with a presumed deleterious effect on both short- and long-term outcomes. We implemented a multidisciplinary treatment protocol in the management of these patients in order to improve complication rates following partial hepatectomy. METHODS A retrospective chart review was completed for all patients < 18 years of age who underwent liver resection at our institution between 2002 and 2019 for primary hepatic cancer. Demographic, intraoperative, postoperative, pathologic, and outcome data were analyzed for perioperative complications using the CLASSIC and Clavien-Dindo (CD) scales, event-free survival (EFS) and overall survival (OS). RESULTS A total of 73 patients were included in the analysis with 33 prior-to and 40 after dedicated provider protocol implementation. Perioperative complication rates decreased from 52% to 20% (p = 0.005) with major complications going from 18% to 10% (p = 0.31). On multivariable logistic regression, protocol implementation was associated with a reduction in any (OR 0.29 [95% CI 0.09 - 0.89]) but not major complications. On multivariate cox models, post protocol implementation was associated with improved event free survival (EFS) (HR 0.19 (0.036 - 0.195). Among patients with a diagnosis of hepatoblastoma (n = 62), the occurrence of a major perioperative complication was associated with a worse EFS (HR=5.45, p = 0.03) on multivariate analysis, however this did not translate into an impact on overall survival. CONCLUSIONS Our results demonstrate that, for children with primary liver malignancies, a dedication of patients to high-volume surgeons can improve rates of complications of liver resections and may improve the oncological outcome of hepatoblastoma.

Abstract
Fetal hepatomegaly is associated with significant fetal morbidity and mortality. However, hepatomegaly might be overlooked when numerous other fetal anomalies are present, or it might not be noticed when it is an isolated entity. As the largest solid organ in the abdomen, the liver can be seen well with US or MRI, and the normal imaging characteristics are well described. The length of the fetal liver, which can be used to identify hepatomegaly, can be determined by measuring the liver from the diaphragm to the tip of the right lobe in the sagittal plane. Fetal hepatomegaly is seen with infection, transient abnormal myelopoiesis, liver storage and deposition diseases, some syndromes, large liver tumors, biliary atresia, and anemia. Some of these diagnoses are treatable during the fetal period. Attention to the associated findings and specific hepatic and nonhepatic imaging characteristics can help facilitate more accurate diagnoses and appropriate patient counseling.©RSNA, 2020.

Abstract
ABSTRACT Diagnostic and therapeutic innovations have changed the way we now approach liver tumours in children and adolescents. Novel imaging tools, increasing awareness, and surveillance has led to early diagnosis of benign and malignant liver tumours. Multidisciplinary interventions have favourably altered the natural course in some liver tumours. The role of liver transplantation is expanding and has become fully integrated into today's therapeutic algorithms. Transarterial locoregional and ablation therapies have been successful in adults and are being explored in children to facilitate resectability and improve outcome. For the first time, North American, Japanese, and European experts have designed a global trial to optimize management of malignant liver tumours and aim to find signature molecular profiles that will translate to individualised treatment strategies.This article aims to offer an overview of recent advances in our understanding of liver tumours in children. It focuses on the paediatric hepatologist's view and their role in the multidisciplinary management of benign and malignant liver tumours.

Abstract
Hepatoblastoma (HB) is a rare tumor, but it is the most common primary liver malignancy in children and comprised of approximately 1% of all pediatric malignancies. Mostly, this tumor is sporadic in nature but can show a syndrome association. Upregulation in Wnt/β-catenin pathway can be there in 70-80% cases of HB. Most often present as abdominal mass and has a raised alpha-fetoprotein levels. Distant metastasis usually occurs in the lungs. HB is classified into 2 broad categories: epithelial and mesenchymal type. The majority of HB are epithelial type. The HB must be distinguished from focal nodular hyperplasia, hepatocellular adenoma, and hepatocellular carcinoma, while small-cell undifferentiated HB from the malignant rhabdoid tumor. The histomorphology and immunohistochemistry are essential for the diagnosis of different HB. The neoadjuvant chemotherapy followed by surgery is the mainstay of the treatment. The 2 well-established prognostic factors of HB are stage and histological type. Herein, we report a case series of common and rare histological variants of HB.

Abstract
Background This study aimed to investigate the critical factors associated with prognosis for children with hepatoblastoma (HB) in mainland China combined with the aspect of health economics and management. Methods This study retrospectively reviewed children with HB in Renji Hospital Affiliated to the Shanghai Jiao Tong University School of Medicine from January 2013 to December 2019. Descriptive analysis was used to describe the essential characteristics. Kaplan-Meier method and Cox proportional hazard models were used to estimate the survival rate and prognosis factors. Results For the 87 children with HB, the average survival was 2,002.8 days (95% CI: 1,798.7-2,206.9 days), the 1- and 5-year survival rates were 87.7% and 78.9%, respectively. Undergoing surgery and sex were independent prognostic factors of childhood HB. Children with HB undergoing hepatectomy (HR: 0.039) or liver transplantation (HR: 0.142) had a better prognosis, while boys were associated with a poorer prognosis (HR: 3.614). The average medical expenses for childhood HB were 40,217.5±3,862.0 CNY and liver transplantation cost more than hepatectomy. Conclusions The results had a comparable survival rate with other studies globally. Surgical therapy and sex are associated with the prognosis of children with HB. The economic burden of childhood HB deserves to be further explored.

Abstract
Vascular liver tumors in the pediatric population can present a diagnostic dilemma. The most common hepatic vascular tumors are hepatic hemangiomas; however the differential diagnosis can also include other benign lesions and malignant masses. Management is unique to the type and nature of the specific lesion. Thus, correct diagnosis and timely intervention is critical. The work up, diagnosis, and management of the different hepatic lesions are discussed in this paper.

Abstract
Contrast-enhanced ultrasonography (CEUS) is a relatively new imaging method for use in children. It is recognized as a safe and easily performed problem-solving method. A premature 10-day-old female infant experienced unusual persistent anemia. The diagnostic workup for the anemia included an abdominal ultrasound examination, which showed pathological formation in the left middle quadrant. MRI was used to further asses the lesion and showed a hypervascular lesion with necrotic areas rising from the left hepatic lobe, mainly showing the pattern that indicates an infantile hepatic hemangioma. Main differential diagnosis, hepatoblastoma, could not be excluded. The crucial examination used to differentiate was CEUS.

Abstract
Liver and biliary pathology in the neonate are rare and include a broad range of structural, neoplastic, infectious, genetic, and metabolic diseases. While most conditions present postnatally, antenatal detection is increasing given recent advances in antenatal imaging capabilities. In certain structural or obstructive liver diseases, antenatal detection now proves essential to help guide treatment and prevent morbidity. We review the epidemiology, pathophysiology, common antenatal diagnostic findings, and recommendations for surgical liver and biliary pathology in the neonate.

Abstract
Mesenchymal hamartoma is a benign tumor of the liver with a poorly understood pathogenesis. It is uncommon in older children, especially after 2 years of age. The signs and symptoms may be nonspecific; therefore, a high index of suspicion is required for diagnosis and treatment. We report a 5-year-old previously healthy male who presented with acute abdominal pain, fatigue, and fever. He was diagnosed with pneumonia initially and treated with antibiotics. A computed tomography (CT) scan done for evaluation of his persistent abdominal pain demonstrated a hepatic mass. Follow-up magnetic resonance imaging (MRI) of the liver demonstrated multiple serpiginous tubular-type structures, read as possible Caroli syndrome. He had a normal abdominal examination and normal biochemistries including alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, and alpha-fetoprotein. He was referred to our institution for second opinion. On further review of his imaging studies, the lesion was thought to be a mesenchymal hamartoma. He subsequently underwent resection of the mass. Pathology confirmed the diagnosis of mesenchymal hamartoma.

Abstract
Hepatoblastoma (HB) is the most common hepatic neoplasm in childhood and the therapeutic outcomes remain undesirable due to its recurrence and metastasis. Increasing evidence shows that dipeptidase 1 (DPEP1) has pivotal function in tumorigenesis in multiple tumors. However, the expression pattern, biological function, and underlying mechanism of DPEP1 in HB have not been reported. Here we showed that DPEP1 was significantly upregulated and was associated with poor prognosis in HB patients. In vitro and in vivo assays indicated that silencing DPEP1 significantly suppressed HB cell proliferation, migration, and invasion, while DPEP1 overexpression exhibited the opposite effect. In addition, we identified that DPEP1 was a direct target of microRNA-193a-5p (miR-193a-5p). Functional experiments demonstrated that overexpression of miR-193a-5p significantly inhibited cell proliferation and invasion of HB cells, while the inhibitory effect could be reversed by DPEP1 overexpression. Moreover, miR-193a-5p was decreased in HB tumor tissues and associated with a poor clinical prognosis. Mechanistically, our results indicated that the miR-193a-5p/DPEP1 axis participated to the progression of HB via regulating the PI3K/Akt/mTOR (phosphatidylinositol-3-kinase/Akt/mammalian target of rapamycin) signaling. In conclusion, our findings suggest that the miR-193a-5p /DPEP1 axis might be a good prognostic predictor and therapeutic target in HB.

Abstract
Mesenchymal tumors in childhood comprise benign and malign entities and differ regarding typical sites of manifestation, age peak and clinical symptoms. In some cases biopsy is mandatory. If nephroblastoma is a possible diagnosis, biopsy must be avoided by all means in order to avoid biopsy tract metastasis. Imaging is used to narrow the differential diagnosis, describe the exact extent of the lesion and deliver complete staging. In pediatric patients sonography and MRI are the most important imaging modalities. Low-dose CT of the thorax serves for assessment of possible pulmonary metastases.

Abstract
Although liver tumors are rare in the pediatric population, they are common in the setting of children with specific risk factors requiring increased awareness and, in some instances, screening. The evaluation of a liver mass in children is largely driven by the age at diagnosis, the presence of any medical comorbidities, and initial testing with alpha fetoprotein and imaging. Specific guidelines for the management of different tumors have been implemented in recent years such that a multidisciplinary approach is ideal and care should be provided by centers with experience in their management.

Abstract
Thorough study is required to decide the appropriate management of hepatic tumors in children. We present a case report of a hepatic embryonal undifferentiated sarcoma with unfavorable prognosis in a nine-year-old girl. After undergoing a detailed cancer characteristics and extension study, a two-stage surgery approach was decided. The hepatic tumor resection was the first procedure to be performed. One week later, under cardiopulmonary bypass, deep hypothermia, and circulatory arrest, thrombectomy of the inferior vena cava and right atrium was accomplished, plus thromboendarterectomy of the right pulmonary artery. During a four-year follow-up, the patient continues to be disease-free.

Abstract
Hepatic angiosarcoma is a rare, aggressive, malignant neoplasm with fewer than 50 cases reported in children. Prognosis is poor, with a minority surviving beyond 2 years after diagnosis. We report eight cases of pediatric hepatic angiosarcoma, diagnosed at a mean age of 3 years. Seven were initially diagnosed with an infantile hepatic hemangioendothelioma (IHHE) or hemangioma and the eighth with a "vascular tumor." Two patients, who received liver transplant, survived. We suggest hepatic hemangiomas can rarely transform into angiosarcomas and a subset of IHHEs (Type II) are actually a low-grade form of angiosarcoma rather than a benign lesion.

Abstract
RATIONALE Mesenchymal hamartomas of the liver is one type of rare liver tumor. PATIENT CONCERNS Mesenchymal hamartomas of the liver (MHL) is rarely reported in the left lobe of the liver in children who are more than 2 years old. It is difficult to distinguish it from liver lesions such as hepatoblastoma in children, and hepatocellular carcinoma and focal nodular hyperplasia in adults. In addition, it is hard to correctly diagnose it without pathological examination. DIAGNOSES Mesenchymal hamartomas of the liver. INTERVENTIONS This patient underwent an operation assisted by the Da Vinci surgical system and the tumor was completely resected. OUTCOMES No tumor recurrence or metastasis was observed 14 months after operation. LESSONS MHL is a benign tumor that is difficult to diagnose due to the lack of specific clinical symptoms and signs. The management of MHL remains controversial. To achieve a good long-term outcome, complete resection of MHL is recommended.

Abstract
Space occupying liver lesions usually present with abdominal pain or abnormal physical findings, such as a palpable abdominal mass or distention. Liver lesions identified in children include benign and malignant neoplasms, inflammatory masses, cysts and metastatic lesions. Two-thirds of liver lesions in children are malignant. Hepatoblastoma accounts for two-thirds of malignant liver tumors in children. Benign lesions of the liver in children include vascular lesions, hamartomas, adenomas, and focal nodular hyperplasia. Although benign and malignant liver masses share some clinical manifestations, however treatment and prognosis differ. Evaluation involves physical examination, imaging evaluation and laboratory investigations such as serological markers [alpha-fetoprotein (AFP)] for malignant liver lesions. Ultrasound is the initial imaging modality of choice because it can detect, characterize, and provide the extent of liver lesions. However, CT or MRI are often subsequently performed for further characterization, assessment of precise extent, and detection of associated metastatic disease in cases of malignant hepatic neoplasm. Serological markers (such as alpha fetoprotein) can be useful in narrowing the differential diagnosis when they are markedly elevated but a substantial number of patients unfortunately do not have high levels of these markers at the time of presentation or cautious interpretation is warranted as AFP level is frequently elevated in infants up to 6 mo of age and may be slightly elevated with benign tumors and with hepatic insult or regeneration. Therefore, a tissue diagnosis is often required to guide subsequent management. The histology and anatomy of a pediatric liver tumor guides the treatment and prognosis.

Abstract
Liver tumours are fortunately rare in children. Benign tumours such as haemangiomas and cystic mesenchymal hamartomas are typically seen in infancy, often before 6 months of age. After that age, malignant hepatic tumours increase in frequency. The differentiation of a malignant from benign lesion on imaging can often negate the need for biopsy. Ultrasound is currently the main screening tool for suspected liver pathology, and is ideally suited for evaluation of hepatic lesions in children due to their generally small size. With increasing research, public awareness and parental anxiety regarding radiation dosage from CT imaging, MRI is now unquestionably the modality of choice for further characterisation of hepatic mass lesions. Nevertheless the cost, length of imaging time and perceived complexity of a paediatric liver MR study can be intimidating to the general radiologist and referring clinician. This article outlines standard MR sequences utilised, reasons for their utilisation, types of mixed hepatocyte specific/extracellular contrast agents employed and imaging features that aid the interpretation of paediatric liver lesions. The two commonest paediatric liver malignancies, namely hepatoblastoma and hepatocellular carcinoma are described. Differentiation of primary hepatic malignancies with metastatic disease and mimickers of malignancy such as focal nodular hyperplasia (FNH) and hepatic adenomas are also featured in this review.. Imaging should aim to clarify the presence of a lesion, the likelihood of malignancy and potential for complete surgical resection. Reviewing and reporting the studies should address these issues in a systematic fashion whilst also commenting upon background liver parenchymal appearances. Clinical information and adequate patient preparation prior to MR imaging studies help enhance the diagnostic yield.

Abstract
With the exception of hemangioma, benign or malignant primary mesenchymal tumors of the liver are seldom encountered. The aim of this review was to discuss the clinical, histopathological, and imaging features of liver hemangiomas (cavernous, capillary, and sclerosed types), liver lipoma, angiomyolipoma, mesenchymal hamartoma, neurofibroma, infantile hemangioendothelioma, epithelioid hemangioendothelioma, myofibroblastoma, angiosarcoma, malignant fibrous histiocytoma, undifferentiated embryonal sarcoma, and nested stromal tumor. In most of these rare liver tumors, radiological findings obtained by cross-sectional imaging may reflect the characteristic pathologic features required for differential diagnosis; however, definitive diagnosis should be confirmed using histopathological examination.

Abstract
The management of hepatic metastatic disease from solid tumors in adults has been extensively described and resection of metastatic liver lesions from colorectal adenocarcinoma, renal adenocarcinoma, breast cancer, testicular cancer, and neuroendocrine tumors (NET) have demonstrated therapeutic benefits in select patients. However, there are few reports in the literature on the management of hepatic metastatic disease in the pediatric and adolescent populations and the effectiveness of hepatic metastasectomy. This may be due to the much lower incidence of pediatric malignancies and the higher chemosensitivity of childhood tumors which make hepatic metastasectomy less likely to be required. We review liver involvement with metastatic disease from the main pediatric solid tumors, including neuroblastoma and Wilms tumor focusing on the management and treatment options. We also review other solid malignant tumors which may have liver metastases including germ cell tumors, gastrointestinal stromal tumors, osteosarcoma, desmoplastic small round cell tumors and NET. However, these histological subtypes are so rare in the pediatric and adolescent populations that the exact incidence and best management of hepatic metastatic disease are unknown and can only be extrapolated from adult series.

Abstract
BACKGROUND Recently, there has been a growing interest in solid benign liver tumors as the understanding of the pathogenesis and molecular underpinning of these lesions continues to evolve. We herein provide an evidence-based review of benign solid liver tumors with particular emphasis on the diagnosis and management of such tumors. METHODS A search of all available literature on benign hepatic tumors through a search of the MEDLINE/PubMed electronic database was conducted. RESULTS New diagnostic and management protocols for benign liver tumors have emerged, as well as new insights into the molecular pathogenesis. In turn, these data have spawned a number of new studies seeking to correlate molecular, clinicopathological, and clinical outcomes for benign liver tumors. In addition, significant advances in surgical techniques and perioperative care have reduced the morbidity and mortality of liver surgery. Despite current data that supports conservative management for many patients with benign liver tumors, patients with severe preoperative symptomatic disease seem to benefit substantially from surgical treatment based on quality of life data. CONCLUSION Future studies should seek to further advance our understanding of the underlying pathogenesis and natural history of benign liver tumors in order to provide clinicians with evidence-based guidelines to optimize treatment of patients with these lesions.
