Oncol Lett 2018; 17:1042-1052. [PMID: 30655864 PMCID: PMC6312964 DOI: 10.3892/ol.2018.9693] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2018] [Accepted: 09/17/2018] [Indexed: 12/13/2022] Open
Abstract
A solitary fibrous tumor (SFT) is a rare mesenchymal tumor. Ex situ hepatectomy and liver autotransplantation are novel methods for the treatment of complicated liver tumors, for example, those involving vascular structures, including the inferior vena cava, which are unresectable by conventional approaches. The present study describes a rare case of a massive hepatic SFT in a 32-year-old female who underwent ex situ hepatectomy and liver autotransplantation to achieve a radical resection. The surgery was without complications. Post-operative histopathological and immunohistochemical examinations revealed an SFT of the liver. The patient was discharged 29 days after the surgery with fully recovered liver function. The routine check-up 3 months after surgery indicated normal liver function and no evidence of recurrence. Additionally, an exhaustive review of available literature was performed to provide a complete overview of the current status of SFTs. In summary, the present study found that ex situ hepatectomy and liver autotransplantation are suitable surgical techniques for treating a giant SFT, as well as other liver neoplasms that are considered unresectable by conventional surgery.

Abstract
Background Solitary fibrous tumours (SFT) are neoplasms of mesenchymal origin that predominantly arise from the pleura. SFT of the liver (SFTL) are a rare occurrence with little number of cases reported in English literature. Malignant cases of hepatic SFT are an even rarer occurrence. For this reason, the prognostic evaluation of SFTLs is unknown and difficult to measure. Methods A search on English literature on “Solitary Fibrous Tumour of the Liver” was conducted on common search engines (PubMed, Google). All published articles, case reports and literature reviews and their reference lists were reviewed. Case report This paper presents a 61-year-old male who was referred to a tertiary hospital in April 2010 with marked hepatomegaly. USS, CT and MRI scans were suggestive of a neoplasm, and the patient underwent a subsegmental IVb resection in June 2010. The specimen demonstrated histological and immunohistochemical features of malignant SFTL with clear resection margins. The patient was followed up regularly for 3 years with imaging and no suggestion of recurrence. Six years after the initial surgery, the patient represented with worsening right upper quadrant pain and dyspnoea secondary to extensive tumour recurrence adjacent to the resection site and metastatic deposits in the pleura. The patient was managed symptomatically and discharged for community follow-up after palliative involvement. Conclusions SFTL are rare with only 84 cases reported in the English Literature including the present case. The average age of patients is 57.1 and occurs in females more than males (1.4:1). Most SFTLs follow a benign course, however, 17.9% of cases displayed malignant histological features. Only three cases including the current case are reported to have both local recurrence and metastasis. Surgical resection remains the mainstay of treatment and appears to be curative of most cases. The rarity of this tumour makes it difficult to evaluate its prognosis and natural course.

Abstract
INTRODUCTION Solitary fibrous tumors of the liver (SFTL) are uncommon tumors; to the present day, less than 50 cases has been reported in the English scientific literature, most of which behaved as benign tumors. The present article reports a new case of SFTL and has the main purpose of updating the current knowledge of SFTL because due to its rarity, its clinical presentation, study, treatment, and prognosis are not well known. The clinical presentation, radiologic study, surgical treatment, immunohistochemical study, and prognosis are updated and comprehensively discussed. METHODS Using the common search engines, a search of the English literature was conducted for "Solitary Fibrous Tumor of The Liver," and the relevant articles were retrieved, reviewed, and analyzed. RESULTS All published articles reported anecdotal SFTLs, or SFTLs were included in large series analyzing solitary fibrous tumors on different sites. CONCLUSION The SFTL is an uncommon neoplasm. The clinical presentation is habitually indolent and its behavior is uncertain. In some cases, the SFTL acts as an aggressive sarcoma with poor prognosis. Currently, only surgery offers a therapeutic opportunity for these patients. Due to the lack of current knowledge of long-term behavior of supposedly benign SFTLs and to the lack of specific therapies, methodical long-term follow-up is essential to ensure the survival of patients treated for SFTL.

Abstract
BACKGROUND Primary hepatic solitary fibrous tumor is a rare neoplasm that originates in the submesothelial tissue of the liver and is frequently misdiagnosed because of its rarity and unfamiliar characteristics. AIM To analyze, summarize and update the clinical and pathological features of primary hepatic solitary fibrous tumor. METHODS We systematically extract the clinical data of 4 cases from the relevant medical records, analyze the macroscopic, histological and immunohistochemical features and review the 59 previously reported cases in the English literatures. RESULTS The patients' mean age 50.75 years (range, 49-52 years), and the gender ratio was 1:1. The tumors ranged in size from 2.3 to 12.0cm (average diameter, 7.85cm). The tumors were composed of spindle cells with oval, fusiform or banded nuclei that were arranged in bundled, storiform or peculiar random patterns. Mitosis and hemangiopericytoma-like vessels were occasionally observed. Immunohistochemically, three cases were positive for Signal transduction and activator of transcription 6, cluster of differentiation 34, B-cell lymphoma-2 and vimentin but were negative for nervous, muscular and hepatocellular markers. Hepatic lobectomy was performed in all cases, and one patient received adjuvant chemotherapy simultaneously. One patient suffered two recurrences without metastasis, and the remaining patients experienced favorable outcomes. CONCLUSIONS A consensus on the essential and definite diagnostic criteria for primary hepatic solitary fibrous tumor must be reached in a timely manner. Signal transduction and activator of transcription 6 is a highly sensitive and specific immunohistochemical marker for primary hepatic solitary fibrous tumor.

Abstract
A 42-year-old male presented right upper abdomen pain for more than 6 days, which misdiagnose calculus of intrahepatic duct and acute cholecystitis. An approximately 1.5 cm x 1.0 cm x 1.0 cm nodule was found and resected in left lateral lobe of hepatic. Pathological examination showed spindle cell and fibroblast -like cells within the collagenous stroma. Immunohistochemically, these spindle tumor cells showed diffuse Vim and Bcl-2 positive reactivity, but S-100 protein and HMB45 were negative. The post-operative course was uneventful. Solitary fibrous tumors of the liver, although rare, should be differentiated from mesenchymal lesions of the liver.

Abstract
Solitary fibrous tumors (SFTs) of the liver are rarely described; only 38 cases have been reported in literature, most of which have shown benign clinical characteristics, and only 3 of these cases exhibited malignant variants. In this study, we present a 24-year-old woman with a 1-month history of a rapidly enlarging abdominal mass and a CT showing an exophytic heterogeneous liver mass with a firm parietal bone mass. The patient underwent a transcatheter arterial chemoembolization (TACE) before operation, and an extended right hepatectomy and craniectomy with a negative margin was performed under general anesthesia. The masses showed histological features of oval spindle cells haphazardly arranged in the classic short-storiform or so-called patternless pattern of solitary fibrous tumors. The tumor cells showed positive immunohistochemical reactions to CD34 and bcl-2. The tumor recurred in the residual liver 2 months after operation, metastatic osteoblastic lesions in the thoracic and lumbar vertebrae were identified 3 months after the operation, and lumbar vertebrae metastasis 7 months after operation paralyzed the patient. The patient underwent percutaneous ethanol injection therapy (PEI) and chemotherapy, but the patient died because of the uncontrolled tumor 16 months after the initial operation. To our knowledge, this is the first case of malignant solitary fibrous liver tumors with skeletal metastasis.

Abstract
Solitary fibrous tumors (SFTs) are a unique group of mesenchymal neoplasms of fibroblastic or myofibroblastic origin. These tumors were originally described as "benign fibrous mesotheliomas" of the pleural cavity and were erroneously thought to be confined to the serosal surfaces (due to a putative mesothelial or submesothelial origin). It is now established that SFTs are ubiquitous neoplasms with both pleural and extrapleural distribution. Extrapleural SFTs commonly occur in middle-aged adults and manifest as asymptomatic, slow-growing, large tumors. Fewer than 5% of patients with SFTs present with symptomatic hypoglycemia. SFTs are histopathologically diverse with a variable admixture of fibroblasts or myofibroblasts, numerous thin-walled vessels, and dense fibrosis. Tumors previously categorized as hemangiopericytomas are now considered cellular variants of SFTs. At imaging, SFTs demonstrate remarkable heterogeneity, with variable degrees of enhancement, necrosis, or hemorrhage. Although most extrapleural SFTs have a benign clinical course, 10%-15% of these tumors demonstrate aggressive behavior in the form of recurrence or malignancy.

Abstract
BACKGROUND Solid fibrous tumor (SFT) is a rare neoplasm, preferentially involving the pleura, rarely the liver. CASE A primigravida between 13-15 weeks gestation developed nausea, vomiting, and abdominal pain. Imaging revealed a large, complex septated mass filling the abdomen and pelvis. At surgery a firm, lobular mass involved in the inferior aspect of the right liver lobe. Open cholecystectomy and hepatic segmentectomy were performed; confirmatory immunohistochemical staining was positive for SFT. CONCLUSION A rapidly growing abdominopelvic mass during pregnancy may be a SFT. The diagnosis and perioperative management of SFT presents multiple challenges to the obstetrician.

Abstract
Hepatic solitary fibrous tumor (SFT) is a rare tumor originating from the mesenchyme. Here we report a new case of SFT in the liver and review the clinical presentation, radiological and operative findings, diagnosis, treatment, and outcome. The patient was a 59-year-old man who presented with progressive fatigue for 3 months and an abdominal mass for 3 days. On laboratory tests, no abnormality was detected except that abdominal ultrasonography revealed a 9.0 × 6.2 cm hypoechogenic mass in the left lobe of the liver. A computed tomographic scan confirmed a hypodense lesion in the left lobe of the liver. The patient underwent left hepatectomy. SFT was diagnosed on the basis of histopathological findings. The patient was free from all symptoms and had no signs of local recurrence after 24 months' follow up.

Abstract
Solitary fibrous tumor (SFT) is a rare neoplasm. Liver parenchyma is a rare location of SFT and, in this case, it usually follows a benign course. We report here the case of a 54-year-old man who presented a large SFT tumor of the right hepatic lobe. The tumor was surgically resected. Local recurrence occurred 6 years later as a 15 cm diameter liver tumor. Histological examination of the resected lesion showed features of an aggressive form of SFT. Two years later, the patient presented with complaints of neck pain and ensuing examinations revealed a tumor of the cranial base. A new surgical resection was performed and histological examination confirmed a metastasis of the SFT. Few weeks later, the patient presented an irreducible psoitis due to an iliac bone metastasis. He died within 1 month.

Abstract
Antiangiogenic treatment activity has been reported in solitary fibrous tumor (SFT), a rare and little chemosensitive sarcoma. We explored the activity of sunitinib malate (SM) in SFT and studied receptor tyrosine kinase (RTK) activation profile. Eleven patients with progressive metastatic SFT resistant to chemotherapy were treated with continuous-dosing 37.5 mg/d SM on a named-use basis. One of them also received the insulin-like growth factor I receptor (IGFIR) inhibitor figitumumab after developing secondary resistance to SM. Besides, biochemical, molecular, and fluorescence in situ hybridization analyses were done in eight naïve SFTs whose cryopreserved material was available to clarify RTK upstream and downstream signaling. In two cases treated with SM and belonging to the naïve series, both pretreatment and posttreatment samples were available. Ten patients were evaluable for response to SM. The best response according to the Choi criteria was six partial response (all with Response Evaluation Criteria in Solid Tumors stable disease), one stable disease, and three progressive disease. Responses lasted >6 months in five patients. The eight naïve samples showed high expression/phosphorylation of PDGFRB, epidermal growth factor receptor, and IGFIR/IR, in the presence of their cognate ligands. Downstream pathways revealed expression/activation of Akt, extracellular signal-regulated kinase 1-2 and, closely related to SFT subtypes, of S6 and 4E-BP1. In two patients, whose pretreatment and posttreatment clinical and molecular status were available, biochemical data confirmed the activity of SM, although they also suggested a possible time-dependent shift of dominant RTK from PDGFRB to IGFIR/insulin receptor. A Response Evaluation Criteria in Solid Tumors partial response to figitumumab corroborated these findings. SM has antitumor activity in SFT, possibly through a PDGFRB-mediated mechanism, but treatments with IGFIR/insulin receptor and possibly epidermal growth factor receptor inhibitors are worth testing.

Abstract
BACKGROUND Portal vein tumour thrombus (PVTT) is highly associated with the progression and metastasis of hepatocellular carcinoma (HCC). However, there are no appropriate cell models of PVTT with which to study the biological and physiological characteristics of PVTT. METHODS Primary cell culture was performed by the use of a successive xenograft line called PVTT-#1, which was obtained from a 60-year-old male HCC patient accompanied by PVTT. RESULTS A successive cell line named CSQT-2 was established. The cell line showed aggressive phenotypes in terms of cell growth, survival, migration, xenograft and metastasis. Moreover, an orthotopic transplantation assay showed that PVTT can be generated in nude mice when CSQT-2 cells were inoculated in the liver and that it shows a typical migratory tendency in the vascular branches of portal vein. Moreover, the established CSQT-2 cells also showed varied expression of tumour-initiating cell (TIC) markers such as CD133, CD90 and EpCAM. CONCLUSION Establishment of CSQT-2 may provide a suitable model with which to investigate the molecular mechanisms of PVTT-related HCC.

Abstract
A solitary fibrous liver tumor is a rare disease that is difficult to diagnose. Radiological findings are not specific and cannot confirm benignity or malignancy. Immunohistologically, CD 34, Vimentin, and Desmin should be used as markers to precisely diagnose solitary fibrous tumors. In most cases, there is low cellularity with no cellular atypia or necrosis, making this a benign lesion. Occasionally, a large size, high mitotic rate, cellular pleomorphism and atypia, and necrosis are interpreted as features suggestive of an increase malignant potential. The outcome of solitary fibrous tumor mostly is related to resectability, although correlated with neither pathological grade nor tumor size. Thus, total surgical resection of the neoplasm is most commonly proposed. Physicians should be alerted that solitary fibrous tumor of the liver can be malignant and can metastasize.

Abstract
Solitary fibrous tumour of the liver is an extremely rare neoplasm, the reported imaging features of which are largely non-specific. We present a case in which dynamic contrast-enhanced CT, MRI and diffusion-weighted MRI findings suggested a diagnosis of solitary fibrous tumour of the liver that was subsequently confirmed by immunohistochemical evaluation.

Abstract
A case of a successfully treated solitary fibrous tumor (SFT) of the liver is reported. An 82-year-old female presented with left upper abdominal discomfort, a firm mass on palpation, and imaging studies revealed a large tumor, 15 cm in diameter, arising from the left lobe of the liver. A formal left hepatectomy was performed. Microscopic evaluation showed spindle and fibroblast-like cells within the collagenous stroma. Immunohistochemistry disclosed diffuse CD34 and positive vimentin, supporting the diagnosis of a benign SFT. The patient remained well 21 months after surgery. SFT of the liver is a very rare neoplasm of mesenchymal origin. In most cases it is a benign lesion, although some may have malignant histological features and recur locally or metastasize. With less than 30 reported cases in the literature, little can be said regarding its natural history or the benefits of adjuvant radiochemotherapy. Complete surgical resection remains the cornerstone of its treatment.

Abstract
INTRODUCTION We report a rare case of solitary fibrous tumour (SFT) of the liver associated with non-islet cell tumour hypoglycaemia (NICTH), which caused a hypoglycaemic coma due to over-production of big-insulin-like growth factor-II. DISCUSSION Although generally benign, SFTs are better characterised, lately due to Western blot, but less than 40 cases have been reported where the liver is the target organ. In only two benign cases has hypoglycaemia been a feature. CONCLUSION We report for the first time a demonstrable relationship between benign liver SFT and NICTH.

Abstract
We report the case of an 84-year-old man who presented with collapse secondary to hypoglycaemia and was found to have a hepatic Solitary Fibrous Tumour (SFT) secreting Insulin-like Growth Factor II (IGF-II). Solitary fibrous tumours of the liver are very rare tumours and have occasionally been described in association with hypoglycaemia. SFT's of other organs have been associated with production of IGF-II but to our knowledge however there are no reports of a SFT of the liver with confirmed IGF-II hypersecretion, and we suggest that this mechanism underlies the hypoglycaemia seen in this case.

Abstract
Sarcomas of the liver are rare. We report a case of intractable hypoglycemia secondary to a solitary fibrous tumor that underwent malignant transformation into a fibrosarcoma. A 70-year-old man presented with a hepatic mass and tumor-associated hypoglycemia which was resistant to medical management. Blood tests were remarkable only for elevated serum insulin-like growth factor (IGF)-2. The hypoglycemia resolved following resection of a solitary fibrous tumor surrounded by a high-grade fibrosarcoma. Real time reverse transcriptase polymerase chain reaction (RT-PCR) measured elevated levels of IGF2 mRNA in both the solitary fibrous tumor and the fibrosarcoma. Immunoblotting demonstrated a series of bands in the size range of pro-IGF2. Unfortunately, disseminated metastases developed 1 year later, concurrent with a recurrence of hypoglycemia, marked again by elevation of serum IGF2. Solitary fibrous tumors of the liver have a real risk of malignant transformation. The severity of the tumor-associated hypoglycemia may parallel the tumor burden and activity. The syndrome is the systemic effect of IGF2 secreted by the tumor. Surgery can treat the hypoglycemia syndrome and the underlying malignancy.

Abstract
Solitary fibrous tumor (SFT) is commonly found on serosal surfaces, and is rarely localized in the liver. There are benign and malignant variants of hepatic SFT. We report a new case of benign SFT. Our patient, a 63-year old woman, who has been followed for 5 years for an asymptomatic liver mass, was admitted for abdominal pain. Ultrasonography (US), CT, MR Imaging and angiography showed the liver mass with typical imaging features, situated in the right hepatic lobe with blood supply from the hepatic artery. Histopathological examination demonstrated a highly vascularized tumor, composed of short spindle cells alternating with hypocellular collagenous regions, with a hemangiopericytoma-like vascular pattern. The immunohistochemical staining was positive for CD 34. Tumor resection was performed. Follow-up 8 years after the resection showed no tumor recurrence or metastasis, thus confirming the initial diagnosis of benign SFT.

Abstract
We report a new case of benign solitary fibrous tumor (SFT) of the liver. A 65-year-old man presented to our unit with upper right abdominal discomfort. On examination abdominal distension was present and palpation showed a large firm mass in the right hypochondrium and epigastrium. The patient's past medical history was not significant and laboratory tests were normal. Ultrasonography and computed tomography showed a large tumor, 20 cm in diameter, in the right lobe of the liver. An extended right hepatectomy was performed. The tumor measured 30 x 28 x 14 cm and weighed 4725 g. Microscopic evaluation showed a benign SFT of the liver with tumor cells typically positive for vimentin and CD34. The postoperative course was uneventful, and the patient is alive 30 months after surgery. This is a rare neoplasm of mesenchymal origin that occasionally involves the liver in adult patients. Most SFTs are benign, but some may have malignant histological features and recur locally or metastasize. Because of their rarity, overall experience has not been significant and little has been published concerning this tumor, Including the present one, 28 cases have been reported in the English literature. Surgery is the mainstay of treatment. Little can be said about the benefits of adjuvant radiochemotherapy in these patients. As SFT of the liver is often a benign neoplasm, chemotherapy or radiotherapy should not be necessary, and should be reserved for when resection is incomplete and/or histological examination reveals features of malignancy. Surgeons must be aware of SFT of the liver, and this neoplasm should be included in the differential diagnosis of a single large hepatic mass.

Abstract
BACKGROUND Solitary fibrous tumours (SFTs) of the liver are very rare entities. Although firstly described to be tumours of pleural origin, SFTs have been reported in various organs such as the meninges, orbit, upper respiratory tract, thyroid, peritoneum, retroperitoneum and soft tissues. Histologically, this tumour often shows alternating cellular and relatively acellular areas. The cellular areas show a wide variety of patterns, making it difficult for it to be differentiated from other mesenchymal tumours. Its immunohistochemical positivity for CD34 and vimentin is believed to be unique. Histiogenesis of SFTs, however, is not yet fully understood. They are known to be usually benign, with only few reports indicating their ability to metastasize. PATIENTS AND METHODS We review the literature on SFTs of the liver and report on the case of a 63-year-old female patient with a large SFT of the right liver. CONCLUSIONS Surgical resection seems to be the treatment of choice. Local recurrence is scarce. Due to the very limited number of cases, data regarding the long-term survival of patients are lacking.

Abstract
Hepatic hemangiopericytomas are rare vascular tumors that may be associated with profound hypoglycemia. Although this tumor is more likely to arise in the lower extremities, pelvis, or retroperitoneum, it may very rarely arise in the liver. Unlike other vascular liver tumors, hemangiopericytomas are frequently large at the time of appearance and may have characteristic imaging features. We present the correlative imaging findings in a patient who had a large symptomatic hepatic hemangiopericytoma that produced intractable and ultimately terminal hypoglycemia. Although hemangiopericytomas seldom occur in the liver, the associated hypoglycemia that is known to occur may suggest the diagnosis and may help in differentiating the mass from other large vascular tumors of the liver.

OBJECTIVE This study describes the imaging features of solitary fibrous tumor of the liver in three patients. CONCLUSION A single large, well-circumscribed, heterogeneously enhancing hepatic mass was present in each patient. These imaging features are suggestive of, but not diagnostic for, solitary fibrous tumor of the liver. The two benign and one malignant solitary fibrous tumors of the liver in this series were indistinguishable from one another on imaging studies.
