BACKGROUND: Liver cancer exhibits geographic and ethnic differences in its prevalence and biology, which implies that it is impractical to develop universal guidelines for all patients. Thus, a meta-analysis was conducted to identify the accuracy of apparent diffusion coefficients (ADCs) for discriminating malignant from benign liver lesions in Asians. METHODS: Eligible studies published in PubMed, Ovid, and Embase/Medline were updated onto October 2014. STATA 12...

Parkinson's disease (PD) is a severe neurodegenerative disorder caused by progressive loss of dopaminergic neurons in the substantia nigra pars compacta of the midbrain. The molecular mechanism of PD pathogenesis is unclear. Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are a common genetic cause of familial and sporadic PD. However, studies on LRRK2 mutant mice revealed no visible dopaminergic neuronal loss in the midbrain. While surveying a LRRK2 knockout mouse strain, we found that old animals developed age-dependent hepatic vascular growths similar to cavernous hemangiomas...

INTRODUCTION: Hemangioma is the most common benign tumor of the liver. Most cases are asymptomatic and do not require treatment. A hemangioma can rarely be pedunculated; as a result, it may undergo torsion and infarction, which can make it symptomatic. CASE PRESENTATION: We report the case of a 45-year-old woman with acute abdominal pain due to torsion of a giant pedunculated hepatic hemangioma around its vascular stalk. CONCLUSIONS: Pedunculated hemangioma of the liver is an uncommon benign tumor, a rare differential diagnosis for a mass located in the upper abdomen...

BACKGROUND: Liver resection or enucleation has been the basic treatment for liver hemangioma. However, there were few reports about laparoscopic surgery (LS) of hemangioma. The intention of this study is to explore the indication and efficacy of LS for laparoscopic hepatectomy (LH) and develop an opinion of these modern developments. PATIENTS AND METHODS: Forty-four patients with LH underwent LS, with hemihepatic vascular occlusion (HVO group n = 24) or modified vascular occlusion (MVO group n = 20), and were retrospectively reviewed, including patients' demography, surgical technique, tumor size and location, blood loss, operation time, complications, modes of hepatic vascular occlusion and changes in postoperative liver function, and the difference in patients demography and operative outcome between HVO and MVO groups were compared as well...

We report a case of a benign liver hemangioma with intense prostate-specific membrane antigen (PSMA) uptake on Ga PET/CT. A 77-year-old man with prostate adenocarcinoma underwent routine staging with PSMA PET/CT. This revealed an intensely PSMA-avid liver lesion. The known prostate adenocarcinoma was localized and had mild uptake. Diagnostic CT and MRI were characteristic of a hemangioma without interval growth over a 3-month period. PSMA PET/CT is becoming increasingly popular for staging in prostate cancer, and the presence of PSMA uptake in extra-prostatic tumors is being increasingly documented...

BACKGROUND: Mutations in the tumor suppressor gene von Hippel-Lindau (VHL) underlie a hereditary cancer syndrome-VHL disease-and are also frequently observed in sporadic renal cell carcinoma of the clear cell type (ccRCC). VHL disease is characterized by malignant and benign tumors in a few specific tissues, including ccRCC, hemangioblastoma and pheochromocytoma. The etiology of these tumors remains unresolved. METHODS: Conditional inactivation of the VHL gene in mouse (Vhlh) was generated to examine the pathophysiological role of the VHL gene function...

AIM: To analyze retrospectively a 5-year experience of human hepatocyte isolation from resected liver tissues with benign disease. METHODS: We established a method of modified four-step retrograde perfusion to isolate primary human hepatocytes. Samples were collected from the resected livers of patients with intrahepatic duct calculi (n = 7) and liver hemangioma (n = 17). Only the samples weighing ≥ 15 g were considered suitable for hepatocyte isolation. By using the standard trypan blue exclusion technique, hepatocyte viability and yield were immediately determined after isolation...

Automatic liver segmentation not only plays an important role in the analysis of liver disease, but also reduces the cost and humanity's impact in segmentation. In addition, liver segmentation is a very challenging task due to countless anatomical variations and technical difficulties. Many methods have been designed to overcome these challenges, but these methods still need to be improved to obtain the desired segmentation precision. In this paper, a fast algorithm is proposed for liver extraction from CT images with single-block linear detection...

BACKGROUND: Laparoscopic major hepatectomy remains a challenging procedure [1, 2]. In the case of giant tumors in the right liver, conventional approach (complete mobilization of the right liver before parenchymal transection) could be dangerous during mobilization because of large volume and weight [3, 4]. We present the case of a pure laparoscopic right hepatectomy for a giant hemangioma using an anterior approach. METHODS: We achieved the informed consent with this patient and approved by the Ethics Committee of the Asan Medical Center...

BACKGROUND & AIMS: Effective treatments are urgently needed for hepatocellular carcinoma (HCC), which is usually diagnosed at advanced stages. Signaling via the insulin-like growth factor (IGF) pathway is aberrantly activated in HCC by IGF2 overexpression. We aimed to elucidate the mechanism of IGF2 overexpression and its oncogenic activities and evaluate the anti-tumor effects of reducing IGF2 signaling. METHODS: We obtained 228 HCC samples from patients who underwent liver resection, 168 paired non-tumor adjacent cirrhotic liver samples, and 10 non-tumor liver tissues from patients undergoing resection for hepatic hemangioma...

We aim to provide an up-to-date summary of infantile hepatic hemangioma (IHH) and its misnomers and to dialectically present the differential diagnosis of these rare entities of the liver. Eligible peer-reviewed articles on hepatic infantile hemangiomas, published between 2000 and 2015, were reviewed for this study. IHH is the most common hepatic vascular tumor in children. Once a liver mass is identified in an infant, the differential diagnosis ranges from vascular malformations to benign and malignant tumors including mesenchymal hamartoma, hepatoblastoma, metastatic neuroblastoma, so careful physical examination, imaging studies, and, if indicated, tumor markers and biopsy, are of pivotal importance to ascertain the correct diagnosis...

Chuan-Xing Wu, Wan-Yuan Bao, Feng Zhu
The aim of this study is to compare the effect of liver enucleation with resection of a giant hemangioma proximal to the hepatic portal vascular structures. From 2008 to 2014, 53 patients with giant hemangiomas proximal to the hepatic portal vascular structures underwent surgery in our hospital by the same surgical team. The indications for surgery included a tumor size greater than 8 cm, a middle size greater than 4 cm but with abdominal pain, a rapidly increased tumor size with uncertain malignancy, or tumor rupture...

Although it has been recognized that those who are positive for anti-hepatitis B core antibody (anti-HBcAb) and negative for hepatitis B surface antigen (HBsAg) with normal liver function could be donors for living donor liver transplantation under appropriate prophylaxis, the negative impact of positive HBcAb on such donors themselves has not been reported. We present a case of a living donor with positive HBcAb, who donated his left lobe for his sister with unresectable giant hepatic hemangioma, and the donor himself developed a de novo hepatocellular carcinoma (HCC) 10 years after donation...
