Primary hepatic angiosarcoma is a rare type of tumor with a poor prognosis. To the best of our knowledge, curative surgery of a metastatic gastrointestinal angiosarcoma from a hepatic angiosarcoma has not been reported previously. In the present report, a case of colonic metastasis from a primary hepatic angiosarcoma is discussed. A rapidly growing mass was identified in the liver of an 84-year-old Japanese male who underwent a subsegmentectomy of the liver. Microscopic examination determined that the mass was an angiosarcoma composed of sheets of spindle cells...

A carcinoid tumor of the pancreas (CTP) is a rare pancreatic neoplasm, and usually presents with carcinoid syndrome (CS). CS consists of the classic symptom triad of cutaneous flushing, diarrhea and valvular disease, and occurs in the majority of patients with liver metastases. In the present study, the patient presented with symptoms of CS. A diagnosis of CTP with CS was suspected due to high levels of urine 5-hydroxyindolacetic acid, and this was confirmed by a fine-needle aspiration biopsy. Computed tomography showed extended lymphadenopathy, but no liver metastases...

Sphingosine kinase 1 (Sphk1) is an oncogenic kinase that is responsible for the phosphorylation of sphingosine to sphingosine-1-phosphate (S1P). Mounting evidence suggests that Sphk1 serves a crucial role in the proliferation and development of a variety of human cancer cells. However, the role of Sphk1 in hepatocellular carcinoma (HCC) has not been fully elucidated. Therefore, the expression of Sphk1 was examined in 127 formalin-fixed, paraffin-embedded HCC tissues using immunohistochemistry, and its clinical implications and prognostic significance were analyzed...

The prognosis of alveolar soft part sarcoma is poor, despite the slow growth of the tumor. A number of cases with spontaneous regression of this rare tumor have been reported. Although the mechanisms underlying spontaneous regression remain uncertain, local immune reaction may be a possible contributing factor. Immunohistochemical expression of human leukocyte antigen (HLA) class I, cluster of differentiation (CD) 3, CD4, CD8, CD20, CD45, CD56, CD68, CD138 and CD163 were assessed in a series of 10 alveolar soft part sarcomas, and the expression profiles were associated with patients' clinicopathological parameters...

Brain metastasis is a common complication in patients with cancer, with lung cancer being the most frequent origin of brain metastases. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have begun to serve a pivotal role in lung cancer treatment and have been reported to demonstrate anticancer activity against brain metastases by penetrating the blood-brain barrier. The present study reports, to the best of our knowledge, the first case of EGFR-mutated non-small cell lung cancer (NSCLC) brain metastasis that was surgically resected while the lesion was responding to the EGFR-TKI erlotinib...

The B-Raf proto-oncogene serine/threonine kinase (BRAF)(V600E) mutation is an important oncogene in the development of papillary thyroid carcinoma (PTC) and has been identified as a risk factor for poor prognosis in patients with PTC. However, whether the BRAF(V600E) mutation is a prognostic marker in patients with solitary papillary thyroid microcarcinoma (sPTMC) has not yet been established. The present study aimed to identify the association between BRAF(V600E) mutation and the clinicopathological features of patients with sPTMC...

Human aspartyl-(asparaginyl)-β-hydroxylase (HAAH) has recently been the subject of several studies, as it was previously observed to be overexpressed in numerous types of carcinoma cells and tissues in patient tumor samples. HAAH has been implicated in tumor invasion and metastasis, indicating that it may be an important target and biomarker for tumor diagnosis and treatment. However, the immunological tools currently available for the study of this protein, including monoclonal antibodies, are limited, as is the present knowledge regarding the role of HAAH in tumor therapy and diagnosis...

Biomarkers that facilitate the prediction of breast cancer prognosis can improve the quality of life in patients during the long period of illness and treatment. Particularly in recent years, with the advent of a more exhaustive analysis of genetic information and gene products, the molecular mechanisms at play during breast cancer have gradually become clearer. In the present study, a systematic review of the literature between 2009 and 2014 was conducted by searching for the keywords 'breast cancer', 'biomarkers', 'diagnosis', 'prognosis' and 'drug response' to clarify the present state of knowledge regarding biomarkers...

Mantle cell lymphoma (MCL) is a mature B-cell non-Hodgkin lymphoma. Patients with MCL generally present with extensive lymphadenopathy and extranodal involvement. To the best of our knowledge, no cases of primary bone MCL with multiple vertebral compression fractures have been reported in the literature thus far. The current study reports the case of a 75-year-old Chinese male patient presenting with lower back pain for 1 year. B symptoms were not observed in the patient's medical history. X-ray revealed osteoporosis, and mixed osteolytic and osteosclerotic lesions in the T10 and L1 vertebrae with decreased height...

Paragangliomas of the organ of Zuckerkandl (OZ-PGL) are rare tumors that, in >70% of cases, occur in association with succinate dehydrogenase complex iron sulfur subunit B (SDHB) or SDHD gene mutations. The aim of the current study was to determine whether a somatic genetic defect in the hypoxia-inducible factor 2α (HIF2α) gene was present in a case of sporadic OZ-PGL. A 32-year-old African female presented with uncontrolled hypertension during the first trimester of pregnancy. A diagnostic hysteroscopy was performed 3 months after delivery, precipitating a hypertensive crisis...

Cardiomyopathies often have a genetic etiology. New genetic diagnostic strategies based on next generation sequencing (NGS)-approaches will continuously increase our knowledge about the genetic basis of cardiomyopathies within the following years. Diagnostics and therapy of rare, genetically-induced cardiac diseases increasingly require special cardiac and genetic knowledge. Interestingly, mutations in the same gene or even identical gene mutations can be associated with different cardiomyopathy phenotypes and can exhibit incomplete penetrance or variable expressivity...

A therapeutic vaccine is meant to activate the patient's immune system to fight and finally control or ideally eliminate an already established infectious pathogen. Whereas the success of prophylactic vaccination is based on rapid antibody-mediated neutralization of an invading pathogen, control and elimination of persistent viruses such as hepatitis, herpes or papilloma viruses requires multi-specific and polyfunctional effector T cell responses. These are ideally directed against continuously expressed viral antigens to keep the pathogen in check...

OBJECTIVES: For women who have been diagnosed with unilateral breast cancer there is an increasing trend for them to request removal of the contralateral healthy breast, so called contralateral risk reducing mastectomy (CRRM). The current literature is only just beginning to identify patient-reported reasons for undergoing CRRM and associated patient reported outcomes. It is also unclear whether women at moderate/high risk of developing a subsequent primary contralateral breast cancer report similar outcomes to those considered to be at low/average risk...

Using a homemade auxiliary device, urinating in a standing position was a feasible alternative to a seated position for women during pregnancy. Pregnant women can experience difficulty voiding in a squatting or crouching position in the absence of a sitting toilet; voiding in a standing position represents a potential alternative. In previous studies [1, 2], voiding in the standing position using a homemade auxiliary device was demonstrated to be a feasible alternative for both young, healthy women [1] and elderly patients with knee osteoarthritis [2]...

Diverticulosis and diverticular disease of the colon are common conditions in Western countries. The incidence and prevalence of these diseases are increasing and becoming significant for health systems. A growing body of knowledge is shifting the paradigm of the pathogenesis and treatment of diverticular disease. Low-grade inflammation, altered intestinal microbiota, visceral hypersensitivity, and abnormal colonic motility have been identified as factors leading to diverticular disease. The risk of developing diverticulitis among individuals with diverticulosis is lower than 10 to 25%...
