Abstract
Angiosarcomas are rare and highly malignant soft tissue sarcomas originating from endothelial cells lining the lymphatic or vascular system. While they predominantly emerge from (sub)cutaneous regions, occurrences have been reported throughout the body. The etiology of angiosarcoma remains elusive in most clinical cases. Nevertheless, several prognosis risk factors play a pivotal role, including chronic lymphedema, therapeutic irradiation, environmental carcinogens, familial syndromes, and the presence of foreign materials like metallic objects and biomedical implants. Despite evidence implicating retained foreign material in angiosarcoma development, understanding its prognosis and pathogenesis remains limited. The pathogenesis of angiosarcoma appears to involve a complex interplay of chronic inflammation, tissue remodeling, and genetic factors that create a conducive microenvironment for malignant transformation. Management of these sarcomas remains challenging due to their infiltrative nature owing to the high chance of metastasis and local recurrence. The primary treatment modalities currently include surgery, radiotherapy, and chemotherapy, but recent advances in targeted immunotherapy and gene therapy hold promise for more effective approaches. This comprehensive review delves into the potential etiological and pathogenic roles of foreign materials, such as metallic objects, biomedical implants, and biomaterials, in the development of angiosarcoma. Further research into the underlying molecular mechanisms could provide valuable insights for tailored management and developing novel targeted therapeutic strategies.

Abstract
PURPOSE OF REVIEW The success of liver transplantation (LT) in treating unresectable hepatocellular carcinoma (HCC) has resulted in interest in LT for other oncologic conditions. Here, we discuss the role of LT for rare oncologic indications including metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs), hepatic epitheliod hemangioendothelioma (HEHE), fibrolamellar hepatocellular carcinoma (FLC), and hepatic angiosarcoma (HAS). RECENT FINDINGS Conditions reviewed have been documented indications for LT in the available literature. We summarize the experience of LT for these indications and proposed management guidelines. SUMMARY GEP-NETs with isolated metastases to the liver can be treated with LT with excellent long-term outcomes (10-year survival 88%) if strict selection criteria are used (low-intermediate grade, Ki-67% < 20%, complete resection of primary tumor, stable disease for 6 months, <50% hepatic involvement). HEHE is a rare hepatic tumor for which LT can be performed with reported 10-year survival around 70%. FLC is a distinct clinical entity to HCC and is optimally treated with surgical resection though experience with LT is described in observational series (5-year survival 50%, recurrence in 10%). HAS is a rapidly progressive tumor with a dismal prognosis with or without treatment, including LT.

Abstract
Angiosarcoma is a very rare soft tissue sarcoma that originates from endothelial cells and typically has a poor prognosis. It is most commonly found in elderly white men and can occur anywhere in the body, particularly in the head, neck, and scalp. Patients who have undergone previous radiation treatment or who have chronic lymphedema also face an elevated risk of this condition. Various genetic changes are suspected to contribute to the development of angiosarcoma, and these changes have been identified as potential targets for treatment. For localized disease, wide surgical resection is often the prudent course of action. A multidisciplinary approach, which may include surgery, radiotherapy, systemic chemotherapy, or immunotherapy, is typically the most effective way to achieve favorable outcomes. In this review, we discuss the general understanding of angiosarcoma and its management, with a particular focus on the current evolving treatments for the disease.

Abstract
OBJECTIVES Primary hepatic angiosarcoma is a rare tumor of the liver that originates from endothelial and fibroblastic tissue, with poor prognosis and lack of standardized treatment. We retrospectively analyzed the clinical characteristics and treatment outcomes of 23 patients with primary liver angiosarcoma treated at an academic sarcoma center. METHODS We screened all patients with primary liver angiosarcoma treated at Stanford between 2000 and 2022. Data was collected from EPIC electronic medical records and included patient demographics, tumor characteristics, treatment modalities, and patient outcomes. Statistical analysis was completed using Python 3.0, while survival curves were generated using the Kaplan-Meier method and Lifelines Packages. RESULTS There were nearly equal numbers of males (11) and females (12) in our study, with most patients aged 70 to 79 at diagnosis. The median overall survival (OS) was 6 months (range 0.07 to 222.6 mo). The 2- and 5-year OS were both 38.6%. 71% of patients received systemic treatment with chemotherapy, while 29% received immunotherapy. Local treatment with surgery or radioembolization was performed in 14% of patients. Three patients in our study displayed particularly improved OS and received various treatments, which ranged from hepatic resection to ipilimumab/nivolumab. CONCLUSION Our study demonstrated that primary liver angiosarcoma has poor outcomes despite treatment. Surgical resection with negative margins is the only curative modality. However, most patients present with advanced disease and are not surgical candidates. Further research is needed to identify more effective systemic therapy options for this devastating disease.

Abstract
Primary hepatic angiosarcoma (PHA) is an exceedingly rare and aggressive neoplasm of mesenchymal origin. PHA makes a very small portion of primary liver tumors and conveys a poor prognosis. Symptomatology can be vague and often mimics primary hepatocellular carcinoma upon presentation. Diagnosis requires careful immunohistopathologic confirmation. We present a case of PHA in a patient with abdominal pain and suspected underlying cryptogenic cirrhosis.

Abstract
Hepatic angiosarcoma (HAS) is an aggressive mesenchymal malignancy that remains underexplored with respect to its etiology and mutational landscapes. To clarify the association between HAS and end-stage renal disease (ESRD), we used nationwide data of the National Health Insurance Research Database (NHIRD) in Taiwan, covering ~99% of the population, from 2001 to 2016. To investigate molecular signatures, we performed whole-exome sequencing (WES) in 27 surgical specimens, including nine ESRD-associated cases. The NHIRD analysis demonstrated that HAS ranked second among all angiosarcomas in Taiwan, with the incidence rates of HAS being 0.08, 2.49, and 5.71 per 100,000 person-years in the general population, chronic kidney disease (CKD), and ESRD patients, respectively. The standardized incidence ratios of HAS in CKD and ESRD patients were 29.99 and 68.77, respectively. In comparison with nonhepatic angiosarcoma, the multivariate regression analysis of our institutional cohort confirmed CKD/ESRD as an independent risk factor for HAS (odds ratio: 9.521, 95% confidence interval: 2.995-30.261, p < 0.001). WES identified a high tumor mutation burden (TMB; median: 8.66 variants per megabase) and dominant A:T-to-T:A transversion in HAS with frequent TP53 (81%) and ATRX (41%) mutations, KDR amplifications/gains (56%), and CDKN2A/B deletions (48%). Notably, ESRD-associated HAS had a significantly higher TMB (17.62 variants per megabase, p = 0.01) and enriched mutational signatures of aristolochic acid exposure (COSMIC SBS22, p < 0.001). In summary, a significant proportion of HAS in Taiwan is associated with ESRD and harbors a distinctive mutational signature, which concomitantly links nephrotoxicity and mutagenesis resulting from exposure to aristolochic acid or related compounds. A high TMB may support the eligibility for immunotherapy in treating ESRD-associated HAS. © 2023 The Pathological Society of Great Britain and Ireland.

Abstract
Angiosarcomas involving the liver can be hepatic primary or metastasis from another anatomic site, which have not been systematically compared. We analyzed a series of liver biopsy or resection specimens carrying a diagnosis of angiosarcoma collected between 2005-2018 at 3 tertiary medical centers. The cohort included 32 patients (20 M, 12 F) with a median age of 64 years old. Nineteen were primary hepatic angiosarcoma (PHA) and 13 metastatic to liver (MA). Males were predominant in PHA (15/19, 78%) compared to MA (5/13, 38%, P=0.025). There was no age difference between the two groups. Five cases had background hepatic cirrhosis, which more likely harbored PHA (4/5, 80%). Multifocality and multi-organ involvement were common in both groups. Tumor size was significantly larger in PHA than MA (10.4 vs. 4.7 cm, P<0.01). Histologically, there were no differences in terms of tumor morphology (spindled vs. epithelioid) and growth patterns (vasoformative vs. solid) between the two groups. Immunohistochemically, all tumor cells were positive for CD31 (28/28, 100%) and ERG (18/18, 100%). Molecular analysis in 5 cases demonstrated different mutation profiles involving different genes including MTOR, PIK3CA, ARID1A, CDKN2A, PTEN, TP53, ATRX, KDR/VEGFR2, etc. On follow-up, 30 (93%) patients died of disease at a median survival of 114 days. Univariate and multivariate analysis revealed PHA and epithelioid morphology to be associated with worse survival (P<0.05) while treatment associated with better survival (P<0.001). Our results confirmed that angiosarcoma, particularly PHA is extremely aggressive. Epithelioid morphology is an adverse prognosticator and may be used for tumor subclassification.

Abstract
Angiosarcomas are a rare subtype representing 1-2% of soft tissue sarcomas. Risk factors are rarely elucidated but radiotherapy and lymphedema are the most common ones, usually following local treatment for local breast cancer. Despite the improvement of our knowledge, the prognosis remains poor with 35-40% of 5 year-overall survival. Local treatment when feasible should include a R0 surgery completed with adjuvant radiation. When metastatic, front lines chemotherapies include doxorubicine or weekly paclitaxel. If possible, in oligometastatic patients, metastasectomy should always be considered allowing the best responses. The knowledge of angiosarcoma's biology is rapidly increasing and new biomarkers are emerging. The use of immunotherapy in particular subtypes including head and neck angiosarcomas shows promising results. The model of the angiosarcoma project, a patient-participating study, seems to be an excellent way to study rare tumors. We should focus our efforts on understanding the underlying molecular biology to propose the best precision medicine for those patients.

Abstract
BACKGROUND This article examines primary hepatic angiosarcoma (PHA) and fat-poor angiomyolipoma (AML), two uncommon vascular cancers. Clinical decisions in these situations are frequently aided by pathology reports and imaging techniques. Uncommon malignant tumors of the vascular endothelium include PHA. Another diagnosis that should not be overlooked when employing contrast-enhanced MR and contrast-enhanced computed tomography (CT) imaging techniques is fat-poor AML, one of the uncommon vascular tumors of the liver. In both conditions, biopsy is the primary means of diagnosis.
CASE SUMMARY In our article, besides the diagnosis of PHA, fat-poor AML, one of the other rare vascular tumors of the liver, is mentioned. In the case, a 50-year-old female patient with VHL Syndrome was admitted to our hospital with nonspecific lesions such as right upper quadrant pain, weight loss, and nausea. Abdominal ultrasonography (US) revealed a hypoechoic heterogeneous lesion with occasional faint contours. In computed tomography, it was observed as a hyperdense nodular lesion in segment 4. Magnetic resonance imaging (MRI) revealed that the lesion did not contain fat. In connection with the known history of VHL Syndrome, we first evaluated the possibility of AML. Thereupon, a histopathological sample was taken and the diagnosis was made as fat-poor AML with 5% fat content.
CONCLUSION In conclusion, PHA in our case report and fat-poor AML in our clinic are two uncommon liver vascular malignancies with comparable incidences. Important imaging techniques like contrast-enhanced US (CEUS), CECT, and CEMRI give us substantial advantages in both cases. However, a biopsy is used to provide the final diagnosis.

Abstract
Surgical extirpation of liver tumors remains a proven approach in the management of metastatic tumors to the liver, particularly those of colorectal origin. Ablative, non-resective therapies are an increasingly attractive primary therapy for liver tumors as they are generally better tolerated and result in far less morbidity and mortality. Ablative therapies preserve greater normal liver parenchyma allowing better post-treatment liver function and are particularly appropriate for treating subsequent liver-specific tumor recurrence. This article reviews the current status of ablative therapies for non-hepatocellular liver tumors with a discussion of many of the clinically available approaches.

Abstract
Background Primary hepatic angiosarcoma (PHA) is a rare malignant tumor of mesothelial tissue origin in the liver. The diagnosis of PHA relies on pathology, and it is frequently misdiagnosed as multiple hepatic hemangioma. Noncirrhotic portal hypertension is a relatively rare pathological manifestation, and there are few reports of PHA as an uncommon cause of noncirrhotic portal hypertension. Case summary A 36-year-old male was admitted with abnormal liver function and suspected drug-induced liver injury (DILI), initially manifesting as multifocal hepatic hemangioma. The liver biopsy revealed features of noncirrhotic portal hypertension (NCPH), and the patient was eventually diagnosed with multifocal hepatic angiosarcoma. Conclusion Patients with PHA may present with NCPH in the liver due to injury to hepatic sinusoids; therefore, it is necessary to consider the possibility of unsampled vascular malignancy when hepatic masses are identified, and the histology is consistent with PHA.

Abstract
An 80-year-old Japanese man presented to our hospital with intra-abdominal hemorrhage due to a ruptured liver tumor. Transcatheter arterial embolization (TAE) temporarily achieved hemostasis, but he died following re-rupture 4 days later. Based on autopsy findings, the liver tumor was diagnosed as hepatic angiosarcoma. Embolic agents used during embolization were identified within the hepatic small interlobular arteries. However, there were no findings of tumor cell necrosis or ischemic change in the angiosarcoma. In the present case, TAE alone did not induce ischemia-induced tumor necrosis, suggesting that TAE might be unsuitable to treat hepatic angiosarcoma. Treatment optimization for ruptured hepatic angiosarcoma is desired.

Abstract
Primary hepatic angiosarcoma (PHA), a rare soft tissue tumor, accounts for only 2% of all liver malignancies. Pathologically challenging, PHA is difficult to be distinguished from other malignancies with ultrasound, Computed Tomography (CT), or Magnetic Resonance Imaging (MRI). Due to late diagnosis and resistance against traditional chemotherapy and/or radiotherapy, only 3% of PHA patients can survive up to two years after diagnosis. To our best knowledge, this case report presents the first case of an advanced diffuse PHA with ruptured hemorrhage that has been effectively treated with TACE and Anlotinib plus Camrelizumab. So far, the patient has received 10 cycles of treatment and is faring well. Latest MRI results show that the tumor has shrunk by 56% and can be assessed as a partial response (PR). This case report includes our experience in treating such a advanced malignancy, and we hope that larger studies on advanced PHA can better quantify the potential benefit.

BACKGROUND Primary hepatic angiosarcoma (PHA) is a rare malignant tumor of the vascular endothelium. Clinical manifestations and laboratory and imaging examinations often lack specificity for PHA. We report a case of PHA, and describe the ultrasound characteristics and characteristic changes in laboratory values associated with PHA.
CASE SUMMARY A 75-year-old woman presented with right upper quadrant abdominal pain for half a month. Magnetic resonance imaging (MRI) at a local hospital revealed multiple liver space-occupying lesions, and she was admitted to our hospital for further diagnosis. Contrast-enhanced ultrasound (CEUS) revealed multiple slightly hyperechoic nodules in the liver, which were suspected to be of malignant vascular origin. Contrast-enhanced computed tomography revealed multiple low-density nodules in the liver, considered to be metastatic hematopoietic malignancies. Contrast-enhanced MRI showed that the multiple liver nodules shared features with infectious lesions. Laboratory examination revealed normal alpha-fetoprotein levels, slightly increased other liver enzymes, decreased platelets, and significantly increased D-dimer levels. Liver biopsy and histopathology confirmed the presence of PHA.
CONCLUSION CEUS can provide valuable clues for the diagnosis of PHA and greatly improve the success rate of puncture biopsy.

Abstract
A 59-year-old woman presented to our hospital with liver dysfunction. Imaging revealed multiple lesions in the liver. The patient was diagnosed with peliosis hepatis using percutaneous and laparoscopic biopsies. However, her condition worsened with the appearance of new, obvious mass-forming lesions. Therefore, she underwent a second percutaneous biopsy of these lesions and was diagnosed with hepatic angiosarcoma. Her condition progressed rapidly, and she died two weeks after the diagnosis. Diagnosis of hepatic angiosarcoma in the early stages is difficult. It should be noted that hepatic angiosarcoma may be associated with the development of peliosis hepatis.

Hepatic Angiosarcoma Post-Renal Transplantation: A Case Report. Transplant Proc 2022; 54:1597-1600. [PMID: 35868873 DOI: 10.1016/j.transproceed.2022.05.015] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 05/05/2022] [Accepted: 05/21/2022] [Indexed: 01/20/2023]
Abstract
BACKGROUND DNA damage and oncogenic viruses increase the risk of cancer post-kidney transplantation, including skin cancer, Kaposi's sarcoma, oral cancer, and non-Hodgkin lymphoma. Here we report an uncommon case of liver angiosarcoma that occurred 8 years after kidney transplantation. This study strictly complied with the Helsinki Congress and the Istanbul Declaration regarding donor source. CASE REPORT A 57-year-old female patient received a cadaver kidney transplantation 8 years ago. She followed a long-term regimen of tacrolimus, mycophenolate sodium, and everolimus, with good renal function. She received annual regular abdominal ultrasound examinations after kidney transplantation, which showed no findings. The patient suffered from several symptoms for approximately 2 weeks before a scheduled abdominal ultrasound: diarrhea, epigastric pain, abdominal fullness, tea-colored urine, and little stool passage. The abdominal computerized tomography showed multiple hepatic tumors in both the hepatic lobes with engorged vasculatures and mild hemoperitoneum. A liver biopsy revealed the histopathology of angiosarcoma. The patient suffered multiple organ failure within one month of treatment. CONCLUSIONS Various post-transplant malignancies are not uncommon after transplantation, warranting periodic screenings for any symptoms in these patients.

Abstract
Vascular sarcomas encompass 3 well-defined sarcoma types: hemangioendothelioma, Kaposi sarcoma, and angiosarcoma. These distinct types are exceedingly rare and very different in terms of clinical behavior, biological features, and treatment approach. Because of this rarity and heterogeneity, it is crucial that vascular sarcomas are treated in sarcoma reference centers or networks, in order to ensure optimal management. The diversity of vascular sarcomas also needs to be taken into account in the design of clinical trials, in order to produce meaningful results that can be consistently translated into everyday clinical practice.

Liver Resection for Primary Hepatic Angiosarcoma: Bicentric Analysis of a Challenging Entity. J Clin Med 2022; 11:jcm11112990. [PMID: 35683376 PMCID: PMC9181818 DOI: 10.3390/jcm11112990] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2022] [Revised: 05/16/2022] [Accepted: 05/22/2022] [Indexed: 11/16/2022] Open
Abstract
Primary hepatic angiosarcoma (PHA) is a rare malignant tumor of the liver, and data on patient outcome after surgical treatment are scarce. The aim of this study was to evaluate postoperative morbidity and overall survival (OS) of patients who underwent hepatectomy for PHA. This is a bicentric retrospective analysis of all consecutive patients who underwent liver resection in curative intent for PHA between 2012 and 2019 at the University Hospital of Muenster and the University Hospital of Bern. Nine patients (five female, four male) were included from both centers. Median age was 72 years (44–82). Most lesions (77.8%) were larger than 5 cm, and mean size of the biggest lesion was 9.4 ± 4.5 cm. Major hepatectomy was performed in four (44.4%), and radical resection (R0) was achieved in six (66.7%) patients. Postoperative complication rate was 88.8%, including 44.4% higher than 3a in the Clavien–Dindo classification. OS survival rates at 1, 2, and 3 years were 44.4%, 22.2%, and 12.5%, respectively, and median OS was 5 months. OS was significantly better after radical resection (R0: 15 months vs. R1: 0 months, p = 0.04), whereas presentation with tumor rupture at diagnosis was associated with the worst OS (0 months vs. 15 months, p = 0.005). Disease recurrence occurred in three patients (33.3%) between three and seven months after surgery. Radical resection remains the only potentially curative treatment option for PHA. However, postoperative morbidity is high, and the overall prognosis remains poor. Multimodal therapy options and management strategies are urgently needed and could improve the prognosis of patients suffering from PHA in the future.

Treatment Outcomes for Primary Hepatic Angiosarcoma: National Cancer Database Analysis 2004-2014. Curr Oncol 2022; 29:3637-3646. [PMID: 35621682 PMCID: PMC9139369 DOI: 10.3390/curroncol29050292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Revised: 05/13/2022] [Accepted: 05/16/2022] [Indexed: 11/16/2022] Open
Abstract
Background: To determine the risk of mortality and factors associated with survival amongst patients diagnosed with primary hepatic angiosarcoma (PHA). Methods: All patients diagnosed with hepatocellular carcinoma (HCC) or PHA from 2004 to 2014 were identified from the National Cancer Database (NCDB). Further analysis was performed within the cohort of patients with PHA to assess the impact of surgery, chemotherapy, radiation, and facility type on overall survival (OS). A multivariable analysis using the Cox proportional methods and a survival analysis using the Kaplan−Meier method were used. Results: A total of 117,633 patients with HCC were identified, out of whom 346 patients had PHA. Patients with PHA had a mean age of 62.9 years (SD 13.7), the majority were men (64.7%), white (85.8%), and had a Charlson comorbidity index (CCI) of zero (66.2%). A third of the patients with PHA (35.7%) received chemotherapy, and 14.6% underwent a surgical resection. The median survival was 1.9 months (1.8−2.4 months) compared to patients with HCC (10.4 months, 10.2−10.5) (aHR-2.41, 95% CI: 2.10−2.77, p < 0.0001). Surgical resection was associated with a higher median survival (7.7 versus 1.8 months, aHR-0.23, 95% CI: 0.15−0.37, p < 0.0001). A receipt of chemotherapy was associated with a higher median survival than no chemotherapy (5.1 versus 1.2 months, aHR-0.44, 95% CI: 0.32−0.60, p < 0.0001), although the survival benefit did not persist long term. Conclusion: PHA is associated with poor outcomes. A surgical resection and chemotherapy are associated with improved survival outcomes; however, the long-term benefits of chemotherapy are limited.

Abstract
DLC1 is a focal adhesion molecule that regulates cell polarity, proliferation, migration, and survival. DLC1 functions as a tumor suppressor and its expression is often down-regulated in various malignant neoplasms of epithelial origin. Recent studies have suggested that lack of DLC1 in endothelial cells may contribute to the development of angiosarcoma, and that DLC1 mutations have been identified in patients with nephrotic syndrome, a disease mainly due to leaky glomerular filtration barriers. To demonstrate whether lack of endothelial DLC1 induces angiosarcoma and/or damages glomerular capillaries leading to nephrotic syndrome, we have extended our analyses on endothelial cell-specific DLC1 knockout mice with focuses on their liver and kidney function. Mice were monitored up to 24 months of age. However, no histological or clinical difference was found between DLC1 knockout and wild type mice, indicating that lack of endothelial DLC1 alone does not compromise kidney and liver function in mice.

Abstract
Objective Angiosarcoma is a rare malignant vascular tumor, and the management and outcome of this disease are not well-described. The aim of this study was to report the incidence, patient demographics, and outcomes of angiosarcoma based on national data. Methods Data on patients with angiosarcoma were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. Inverse probability treatment weights (IPTW) were used to assess the survival benefit of operation with additional chemo or radiation therapy compared to operation alone. These variables were further compared against patients who did not receive an operation despite being initially offered one. Cox regression was used to assess survival. Statistical analyses were performed on RStudio. Results For this study, 5,135 patients (46% men; median age 69, range 0–102) with angiosarcoma were identified in the SEER database between 1975 and 2016. The age-adjusted incidence rate was 1–4%. Patients were mostly non-Hispanic Caucasian (75.4%). The average tumor size was 4.7 cm, range (.1–98.9). Tumor grades were high at presentation (Grade III 17.2, Grade IV 19, and unknown 50.6%), but half were considered localized tumors. Most patients underwent an operation (66.1%). In 5.6% of patients, the operation was recommended but not performed. The overall 5-year survival was 26.7% (95% CI 25.4–28.1%). IPTW with adjusted Cox proportional hazard model demonstrated worse survival, showing that operation compared to no operation and operation with chemo/radiation compared to operation alone had worse survival between months 0 and 25 but had improved survival after month 25. Conclusions The incidence of angiosarcoma is low and long-term survival is poor. Multimodal therapy in the form of neoadjuvant or adjuvant chemo/radiation therapy offers significant long-term survival benefits over operation alone.

Abstract
BACKGROUND AND OBJECTIVES Visceral angiosarcoma is rare and aggressive, accounting for 2% of soft tissue sarcomas. Using a national data set, we examine determinants of outcomes for patients presenting with this rare disease. METHODS The 2004-2015 National Cancer Database was queried for patients with visceral angiosarcoma. Trends in treatment and outcomes were examined. Factors affecting overall survival (OS) were assessed with log-rank and Cox regression. RESULTS Eight hundred and ninety-three patients with visceral angiosarcoma were identified (median age 65 years, male [63%], Charlson comorbidity index <1 [86%]). Tumor size was <5 cm in 20.7%, and 34.2% were moderate/high grade. Median OS was 3.8 months (95% CI: 3.4-4.4). By multivariate analysis, increased tumor grade and size, and liver/biliary origin demonstrated worse OS while surgery, radiation, and systemic chemotherapy demonstrated improved OS (all p < 0.001). Survival was similar between patients achieving R0 resection and those with R1/2 resection receiving chemotherapy by Kaplan-Meier analysis. CONCLUSIONS Visceral angiosarcomas are rare tumors with poor outcomes. Liver/biliary origin, higher tumor grade, and larger tumor size demonstrate worse outcomes. While R0 resection remains the mainstay of treatment, patients with R1/R2 resection have improved survival with addition of chemotherapy. Consideration should be made for multimodal therapy in these patients.

Abstract
PURPOSE Hepatic angiosarcoma is very rare malignancy and more common in men than in women. To date, only a few female cases of liver angiosarcoma have been reported. Here, we report a female case of liver angiosarcoma, first detected in Vietnam, with a high malignancy stage, rapid progression, and poor prognosis. CASE PRESENTATION A 61-year-old woman was admitted to the Bach Mai Hospital with fatigue, anorexia, weight loss, and severe pain in the right upper quadrant for 2 weeks prior. Clinical examination detected a firm 4-cm hepatomegaly below the right costal margin and grade I splenomegaly. Abdominal ultrasonography and CT revealed diffuse lesions in the entire liver parenchyma, spreading to the spleen, while MRI showed signs of bone metastasis. Blood tests showed elevated transaminase enzymes, especially Gamma Glutamyl Transferase 501 U/L; thrombocytopenia; no anemia; and other tumor markers such as AFP, CEA, and CA19-9 were within normal limits. On CT images, the dots and nodules in the liver and spleen appeared hyperenhanced in the arterial phase and washout in the venous phase. The results of both histopathology and immunohistochemistry showed liver angiosarcoma. Surgery and radiation were not indicated due to the suspicion of bone metastasis. Chemotherapy with doxorubicin at a dose of 60 mg/m2 and intravenous infusion once every 21 days was administered. Unfortunately, during the first dose of chemotherapy with doxorubicin, side effects appeared. Since the disease developed continuously and uncontrollably, the patient was subsequently exhausted, anemic, presented peritoneal fluid, and eventually died of intra-abdominal bleeding. CONCLUSION For the diagnosis of liver angiosarcoma, ultrasound-guided liver biopsy could be applied for safe and effective histopathology, and selective embolization of the hepatic artery is necessary to prevent bleeding complications. The disease has a very poor prognosis, and if chemotherapy does not respond, the patient can die within six months of diagnosis.

Abstract
Primary hepatic angiosarcoma (PHA) is a rare and aggressive mesenchymal liver tumor with a poor prognosis and high mortality. Treatment options are limited to palliative chemotherapy with surgical resection reserved for the few cases that present early. We present a case of a patient who presented with jaundice and elevated liver enzymes. Imaging identified a diffusely heterogeneous liver consistent with cirrhosis, findings of portal hypertension, and 2 ill-defined liver lesions. Biopsy results confirmed PHA. Primary hepatic angiosarcoma does not have a typical presentation but should be considered for any patient presenting with an infiltrative liver mass.

Abstract
Although deep vein thrombosis, as well as subsequent pulmonary embolism, is one of the major and fatal complications in cases of malignant neoplasm, it most often occurs after the diagnosis or treatment of the tumor. On the other hand, malignant tumors that develop with deep vein thrombosis as a specific initial symptom are extremely rare. Here, we report a case of angiosarcoma of the iliac vein, whose initial symptom was dyspnea due to pulmonary embolism. Although angiosarcoma arising directly from major blood vessels is rare, literature reviews, as well as our case, indicate that thromboembolism is an important initial symptom related to angiosarcoma from thick blood vessels and may contribute to immediate diagnosis and therapeutic intervention.

Abstract
Background Malignant vascular tumors (MVTs) are rare and often misdiagnosed due to wide range of clinical presentations, varied histology, and exquisite imagining features. We aim to characterize two different types of MVTs of the liver: hepatic angiosarcomas (HA) and hepatic epithelioid hemangioendotheliomas (HEHE). Methods Data on HA and HEHE between 1975 and 2016 were extracted from the SEER database and analyzed. Results A total of 366 patients with HA were identified where 64.2% were male and 79% of White race. The median age at diagnosis was 64 ± 16.2 years. Distant metastasis was found in 24% of patients, regional disease in 22.1%, and localized disease in 21.3%. The median overall survival for HA was 2 months. For HEHE, 120 cases were identified, 32.5% were male and 80% of White race. The median age of diagnosis was 51 ± 16.8 years. Distant metastasis was found in 37.5% of patients, regional disease in 27.5%, and localized disease in 20%. The median overall survival was 182 months. Conclusion Patients’ demographics such as race, age, and gender may assist in elucidating distinct subtypes of MVTs. HA is an aggressive tumor despite intervention. Patients with HEHE tumors have significantly better survival compared to patients with HA. Further studies are needed to deepen our knowledge about the histopathology of these tumors, the outcomes of liver transplantation as a therapeutic alternative, and available molecular targets for MVTs.

Abstract
Increased lymphangiogenesis and lymph node metastasis, the important prognostic indicators of aggressive hepatobiliary malignancies such as hepatocellular cancer and cholangiocarcinoma, are associated with poor patient outcome. The liver produces 25% to 50% of total lymphatic fluid in the body and has a dense network of lymphatic vessels. The lymphatic system plays critical roles in fluid homeostasis and inflammation and immune response. Yet, lymphatic vessel alterations and function are grossly understudied in the context of liver pathology. Expansion of the lymphatic network has been documented in clinical samples of liver cancer; and although largely overlooked in the liver, tumor-induced lymphangiogenesis is an important player, increasing tumor metastasis in several cancers. This review aims to provide a detailed perspective on the current knowledge of alterations in the hepatic lymphatic system during liver malignancies, as well as various molecular signaling mechanisms and growth factors that may provide future targets for therapeutic intervention. In addition, the review also addresses current mechanisms and bottlenecks for effective therapeutic targeting of tumor-associated lymphangiogenesis.

Abstract
Hepatic angiosarcoma is a rare disease, and hepatic hemangiosarcoma with Kasabach-Merritt syndrome (KMS) is even rarer. Although there have been several reports about KMS caused by hepatic angiosarcoma, there has been no mention of successful treatment regimens for hepatic angiosarcoma with KMS. A 64-year-old female patient presented with right upper abdominal pain and multiple cutaneous purpuras for 10 days. Blood analysis revealed that hemoglobin, platelet and fibrinogen were significantly decreased, prothrombin time was prolonged, fibrinogen degradation products were increased. Contrast-enhanced computed tomography scan of the abdomen demonstrated a large mass in the right lobe of the liver, which is pathologically suggestive of hepatic angiosarcoma. Based on the above examination, the patient was diagnosed with KMS caused by hepatic angiosarcoma. Repeated transfusion of blood products could only temporarily improve the coagulation function of the patient. After transarterial chemoembolization, the patient experienced a long-term improvement of blood clotting, and the patient's survival increased by six months. Transarterial chemoembolization should be considered one of effective therapies for hepatic angiosarcoma with KMS.

Abstract
Background. Hepatic angiosarcoma is an uncommon, malignant, primary liver tumor, comprising 2% of liver cancers and accounting for < 1% of all sarcomas. Patients usually present with nonspecific symptoms, such as fatigue, weight loss, right upper quadrant pain, anemia, which leads to late diagnosis of an advanced stage tumor. The median life expectancy after the diagnosis of hepatic angiosarcoma is about 6 months, with only 3% of patients surviving more than 2 years. Liver failure and hemoperitoneum are the leading causes of death in patients with liver angiosarcoma. In rarer cases, it might cause paraneoplastic syndromes such as disseminated intravascular coagulopathy. The treatment of angiosarcomas is complicated as there are no established and effective treatment guidelines due to the tumor’s low frequency and aggressive nature. Case summary. We present the case of a 68-year old woman who was admitted to the hospital due to fatigue and severe anemia (hemoglobin 65 g/l). Laboratory results also revealed high-grade thrombocytopenia (8 × 109/l). The abdominal ultrasound and computed tomography scan showed multiple lesions throughout the liver, spleen and kidneys. After the histological examination of the liver biopsy, the patient was diagnosed with hepatic angiosarcoma. The treatment with first-line chemotherapy (doxorubicin) was initiated despite ongoing paraneoplastic syndrome – disseminative intravascular coagulopathy. However, the disease was terminal, and the patient died 2 months since diagnosed. Conclusions. Hepatic angiosarcoma is a rare and terminal tumor. Therefore, knowledge about its manifestations and effective treatment methods is lacking. Disseminative intravascular coagulopathy is a unique clinical characteristic of angiosarcoma seen in a subset of patients.

Abstract
INTRODUCTION AND IMPORTANCE Primary hepatic angiosarcoma (PHA) is a rare and aggressive liver malignancy of endothelial cell origin and is associated with poor outcome. Pre-operative confirmation of the diagnosis is challenging, as clinical and radiological findings are generally non-specific. Very rarely, spontaneous haemoperitoneum may occur due to the spontaneous rupture of previously undiagnosed PHA. CASE PRESENTATION We describe a case of a 28-year-old male with haemoperitoneum due to the rupture of previously undiagnosed PHA. After failing to respond to the non-operative measures, the patient underwent emergency partial liver resection and recovered without any post-operative complications. Histopathological examination of the specimen confirmed the diagnosis of PHA. Two months after the operation, the patient represented with advanced metastatic disease and disseminated intravascular coagulation (DIC). The patient died one month after discharge. CLINICAL DISCUSSION A patient with PHA presents a diagnostic challenge due to its rare incidence and non-specific clinical findings. Spontaneous intra-abdominal haemorrhage can occur due to PHA rupture and carries a dismal prognosis. In addition to emergency haemorrhage control, complete surgical resection with clear margins is the definitive treatment to date, however, most cases of PHA are unresectable at diagnosis and recurrence is common even after complete resection. CONCLUSION PHA is associated with very poor outcomes, due to its rapid progression, early recurrence, and metastatic nature. The median survival is approximately 5 months. Haemoperitoneum secondary to rupture of previously undiagnosed PHA is uncommon and is a poor prognostic indicator. Complete surgical resection of the disease is challenging and there is no established treatment.

[PMID: 33661569 PMCID: PMC9878303 DOI: 10.1002/pbc.28864] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 11/19/2020] [Accepted: 12/09/2020] [Indexed: 01/28/2023]
Abstract
BACKGROUND Hepatic vascular malignancies (HVMs) are rare malignancies, with no standardized treatment regimens. The most common HVMs, angiosarcoma and malignant epithelioid hemangioendothelioma (EHE), are often grouped together in the literature complicating our ability to achieve reliable survival data and treatment strategies. OBJECTIVE To compare the disease characteristics of HVMs, with a subanalysis on pediatric patients. METHODS The 2016 National Cancer Database was queried for patients with HVMs using international classification of diseases-oncology-3 (ICD-O-3) codes yielding 699 patients. Descriptive statistics, chi-square, Kaplan-Meier, and log-rank analyses were performed. RESULTS We found 478 patients (68%) with angiosarcoma and 221 (32%) with EHE. The median (Q1, Q3) age for angiosarcoma patients was 65 years (56, 75) versus 54 years (37, 65) in EHE patients (P < .001). The rate of resection was lower in patients with angiosarcoma than EHE (13% vs 32%, P < .001). The mean 1-, 3-, and 5-year overall survival for angiosarcoma patients was 17%, 8%, and 6%, respectively, versus 80%, 65%, and 62% in EHE patients (P < .0001). A subgroup analysis was performed on pediatric patients demonstrating six with angiosarcoma and 10 with EHE. The mean 1-, 3-, and 5-year overall survival for pediatric angiosarcoma patients was 67%, 50%, and 50%, respectively, and 90%, 90%, and 90% for pediatric EHE patients. CONCLUSION In the largest study of HVMs to date, we found angiosarcoma has significantly worse overall survival than EHE. Pediatric patients appear to have improved survival and higher rates of resection. Larger studies of HVMs are needed to clearly differentiate tumor types, standardize care, and improve survivorship.

Clinical characteristics and surgical treatments of primary hepatic angiosarcoma. BMC Gastroenterol 2021; 21:156. [PMID: 33827427 PMCID: PMC8028144 DOI: 10.1186/s12876-021-01743-3] [Citation(s) in RCA: 6] [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: 01/29/2021] [Accepted: 03/30/2021] [Indexed: 12/26/2022] Open
Abstract
PURPOSE Primary hepatic angiosarcoma is a very rare and highly malignant tumor with poor prognosis. It is difficult to diagnose because of the lack of typical clinical features, and the treatment protocols for PHA are also not clear. Therefore, this study wants to find out the clinical characteristics and surgical treatments of primary hepatic angiosarcoma. METHODS Among 8990 patients diagnosed with primary malignant tumor of the liver from January 2000 to December 2019 in our hospital, only four patients were diagnosed with primary hepatic angiosarcoma. The demographics, clinical manifestation, past history, serology test results, MRI features, pathology, treatment modality and prognosis of four patients were collected and analyzed. RESULTS Three of four patients had no clinical symptoms, while one patient's symptom was abdominal pain. The levels of tumor markers of all four patients were within the normal reference range and serological tests were negative for hepatitis B and C virus. The MRI imaging findings of all four patients were mixed mass with highly disordered vascular characteristics. All four patients were misdiagnosed preoperatively. One patient who underwent hepatic lobectomy was still alive for about 18 months after surgery. One patient who underwent hepatic lobectomy has survived for only 6 months due to severe pneumonia. The other two patients who received transarterial chemoembolization survived 16 months and 11 months respectively. CONCLUSION The clinical symptoms of primary hepatic angiosarcoma are not typical, and primary hepatic angiosarcoma is easily misdiagnosed. The typical imaging manifestations are structural disorder and heterogeneous tumor. Hepatic lobectomy and transarterial chemoembolization may be important surgical treatments to improve the prognosis of patients.

Abstract
Hepatocholangiocarcinoma, fibrolamellar carcinoma, hepatic haemangioendothelioma and hepatic angiosarcoma represent less than 5% of primary liver cancers. Fibrolamellar carcinoma and hepatic haemangioendothelioma are driven by unique somatic genetic alterations (DNAJB1-PRKCA and CAMTA1-WWTR1 fusions, respectively), while the pathogenesis of hepatocholangiocarcinoma remains more complex, as suggested by its histological diversity. Histology is the gold standard for diagnosis, which remains challenging even in an expert centre because of the low incidences of these liver cancers. Resection, when feasible, is the cornerstone of treatment, together with liver transplantation for hepatic haemangioendothelioma. The role of locoregional therapies and systemic treatments remains poorly studied. In this review, we aim to describe the recent advances in terms of diagnosis and clinical management of these rare primary liver cancers.

Unexpected death due to spontaneous splenic rupture: A rare case in splenic angiosarcoma. Leg Med (Tokyo) 2020; 47:101785.

Abstract
Splenic angiosarcoma (SA) is a rare disease that can cause spontaneous splenic rupture leading to unexpected death. The rare incidence and non-specific clinical presentations made the early correct diagnosis of SA impossible in clinical practice. Even with medical intervention, 80% of patients died within 6 months after diagnosis. Here, we report a man who had complained of abdominal distension for 2 weeks and succumbed to the disease nine hours after admission. Diagnosis of hepatic and splenic angiosarcomas was based on post-mortem histopathological examination and immunohistochemistry, and the cause of death was hemorrhagic shock caused by spontaneous splenic rupture secondary to SA. This present case was the first forensic autopsy of spontaneous splenic rupture secondary to SA, which can highlight the diagnosis of rare diseases in forensic practice, and forensic pathologists should bear in mind these rare diseases even in routine practice.

Abstract
Angiosarcomas (AS) are a diverse group of soft tissue sarcomas, arising from blood and lymphatic vessels. They frequently present in the elderly, and in patients with previous radiation or lymphedema. A wide range of genetic derangements contribute to their development, and AS histology is often high-grade in keeping with aggressive disease biology. The clinical presentation, while often innocuous, is marked by its infiltrative and aggressive nature, with a proclivity for metastatic spread, and outcomes are often poor. Surgery is performed for localized, resectable cases. A multidisciplinary approach, appropriately employing surgery, radiation, chemotherapy, or potentially recently approved immune-oncology agents, can result in positive outcomes.

Abstract
BACKGROUND Angiosarcoma is an aggressive and malignant neoplasm. Primary hepatic angiosarcoma is extremely rare and accounts for only approximately 5% of all angiosarcomas. Therefore, many doctors do not know enough about this disease; this lack of knowledge motivated us to perform this study. METHODS We carried out a systematic review of the literature published worldwide from 1990 to 2019 to study the main characteristics, demographics, treatment and prognosis of primary hepatic angiosarcoma. RESULT A total of 219 patients were included in this study. Patients were mainly middle-aged and elderly at diagnosis, with an average age at onset of 56.7 years. The vast majority of patients (61.5%) presented with abdominal pain or distension. Of 143 patients with clear records of metastasis, 31.5% (45 patients) had distant metastasis. The median overall survival time was only 6 months, and the 1- and 2-year survival rates were 30.4 and 17.3%, respectively. Sex, age, tumor size and metastasis at diagnosis showed no correlation with survival rate. Hepatic rupture was a significant predictor of survival. Surgery is a major treatment choice, and adjuvant chemotherapy can improve the prognosis of patients. Hepatic artery embolization is mainly used in cases of tumor rupture. However, liver transplantation is not advised. CONCLUSION We presented an overview of the demographics, tumor characteristics and treatment outcomes of the largest number of primary hepatic angiosarcoma patients investigated to date. We highlight the use of routine physical examinations and surgery combined with adjuvant chemotherapy to improve the outcomes in these cases.

Abstract
Imaging of primary hepatic neoplasms in patients at risk for hepatocellular carcinoma (HCC) and in patients with otherwise normal livers relies on proper multiphase image acquisition technique, with emphasis on a high-quality, late arterial phase, using either CT or MRI for accurate image interpretation. The introduction of liver imaging reporting and data system in 2011, with subsequent multiple updates, the most recent in 2018, has provided standardization of image interpretation, reporting and management recommendations for liver observations in patients at risk for HCC. This review article will emphasize key points of imaging primary liver tumors with emphasis on liver imaging reporting and data system, including strengths of this system. We will also review imaging of less common primary liver tumors such as cholangiocarcinoma and angiosarcomas. Imaging pitfall associated with primary liver malignancies will be demonstrated as well as ways to mitigate them. Finally, imaging and reporting of findings following locoregional treatment of HCC will be reviewed.

Abstract
Primary hepatic angiosarcoma (PHA) is a rare mesenchymal liver tumor, accounting for 0.1–2% of primary liver malignancies. The clinical presentations of PHA are variable, from asymptomatic to liver failure or complicated with tumor rupture. The diagnosis of PHA is difficult due to the lack of specific clinical manifestation and investigation results, which can be confused with other liver tumors resulting in late diagnosis. However, there is currently a paucity of effective therapeutic approaches. We advocate early diagnosis with radiological imaging and histopathology because most of them are diagnosed in late-stage and carry a grave prognosis. Surgical resection remains the mainstay of treatment, which can significantly prolong survival. Chemotherapy, including transarterial chemoembolization, is an option for palliative treatment. Unfortunately, molecular treatment has limited efficacy and liver transplantation is also not recommended due to high rate of recurrence. We present a case series of four patients with biopsy-proven PHA which had distinct presentations and clinical courses.

Abstract
Background Hepatic angiosarcoma is a rare malignant tumor featured by highly aggressive behavior and poor prognosis. There are few reports about diffused hepatic angiosarcoma with Kasabach-Merritt syndrome till now. Case presentation A male patient with the chief complain of hepatic space-occupying lesion accompanied by disturbance of consciousness and jaundice. Hyperbilirubinemia, anemia, thrombocytopenia, prolonged prothrombin time, hypofibrinogenemia, decreased prothrombin activity, and increased fibrinogen degradation product and D-dimer were confirmed by blood analysis; multiple focal hypodense lesions in liver was detected by abdominal computed tomography. Liver failure and Kasabach-Merritt syndrome induced by hepatic hemangioma was diagnosed before operation and liver transplantation was performed. Hepatic angiosarcoma was finally proven by postoperative pathology. This patient died of tumor metastasis 2 months after operation. Conclusions Hepatic angiosarcoma which can generate Kasabach-Merritt syndrome and even liver failure has an extremely poor prognosis; liver transplantation option should not be considered in hepatic angiosarcoma regardless of the reason.

Initial clinical radiological findings and staging to predict prognosis of primary hepatic angiosarcoma: A retrospective analysis. PLoS One 2019; 14:e0225043.

Abstract
OBJECTIVE Primary hepatic angiosarcoma (PHA) is extremely rare and most patients die within 12 months of diagnosis. The object of the study is to determine the association of initial clinical-radiological features and staging with outcomes in patients with PHA. METHODS The medical records of adult patients with PHA were retrieved from an electronic medical record database and a pathology database and retrospectively reviewed. During 10 years, 22 eligible patients were included. Data extracted focused on the information before the first formal treatment with a pathological proof, including demographic characteristics, medical history, laboratory data, preliminary images, histopathological records, treatment, and follow-up survival period. Two radiologists blindly re-analyzed preliminary images of all 22 patients together and recorded tumor features and imaging stage based on the American Joint Committee on Cancer (AJCC) 8th edition tumor-node-metastasis (TNM) Staging System for hepatocellular carcinoma. A radiologist compiled the initial clinical data and preliminary image stage to analyze the association with patients' survival outcome. RESULTS Higher aspartate aminotransferase (AST), higher total bilirubin (TB), lower albumin (ALB), longer prothrombin time (PT) and lower platelet count of serum relative to the normal reference range were more common in patients who survived ≤ 90 days (all P < 0.05). Overall survival was much better in patients with single PHA than in those with other tumor patterns of multiple PHA (all P < 0.05). Overall survival determined by preliminary imaging showed significant differences between stage I and stage III (P = 0.044), stage I and stage IV (P = 0.011), and stage III and IV (P = 0.047). No patients were at stage II. CONCLUSIONS Initial serum levels of ALT, TB, ALB, and PT, platelet count, single mass in liver, and preliminary imaging staging could help predict survival outcomes of patients with PHA.
