Gastrointestinal stromal tumors (GISTs) of the stomach presenting as an intra-abdominal abscess are extremely rare. We herein report a case that underwent successful laparoscopic resection of gastric GIST presenting with an intra-abdominal abscess. A 70-year-old man presented with a 3-day history of acute upper abdominal pain with a fever. Laboratory data showed an elevated white blood cell count and C-reactive protein level. A CT scan revealed a mass of mixed solid and fluid components, measuring 5.5 cm, in the adjacent lesser curvature of the stomach...

Gastrointestinal stromal tumor is a rare pathology. GISTs account for 0.3-1% of all tumors of the gastrointestinal tract. At the same time, this type of cancer is the most common, malignant, non-epithelial tumor of the gastrointestinal tube. Over 90% of GISTs are found in the stomach and small intestine. This cancer usually develops without characteristic clinical symptoms and is diagnosed incidentally. This clinical situation, in which the first symptom of a GIST-pattern tumor includes a fully-symptomatic, non-complicated umbilical hernia, is an unprecedented anomaly...

High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) to rescue hematopoiesis is considered standard care for patients with a relapsed chemosensitive lymphoma, but diagnosis of lymphoma has been a risk factor for poor mobilization in several studies. The aim of this prospective noninterventional clinical audit was to review the mobilization strategies used by EBMT centers in relapsed lymphoma and to evaluate their efficacy. Between 2010 and 2014, 275 patients with relapsed lymphoma from 30 EBMT centers were prospectively registered...

Premature ovarian failure (POF) refers to the presence of ovarian atrophic permanent amenorrhea in women under the age of 40. The pathogenesis of POF remains to be fully elucidated. Telocytes are a group of specialized cells with a small cell volume and very long cytoplasmic prolongations with dichotomous branching. Previous studies have indicated that telocytes function to support the trachea and serve as stem cell niches. Although it has been confirmed that telocytes are present in numerous organs in mammals, it remains to be determined whether they are present in ovarian tissues and whether they are involved in the development of POF...

Synovial sarcoma is one of the poorly differentiated malignant soft tissue tumour occuring commonly among young adults in the extremities. We report a 50-year-old female presenting with a soft tissue mass in the right palm. On examination, a single firm and non tender swelling was noticed adjacent to the thenar muscles. Radiology suggested a benign soft tissue lesion. The swelling, clinically thought to be a lipoma, was excised and sent for histopathological examination. Microscopy showed a highly cellular tumour arranged in nests, cords and pseudo glandular pattern separated by dense fibrocollagenous tissue...

Solitary fibrous tumors (SFTs) are uncommon spindle-cell tumors of mesenchymal origin initially described in the pleura and subsequently in other extra-pleural sites. These tumors are categorized as tumors of 'intermediate malignancy' under the World Health Organization classification of soft tissue tumors. SFT was virtually non-existent or misdiagnosed until its characteristic features, particularly the strong and diffuse immuno-reactivity to CD 34 were described. Extra-pleural manifestations of SFT, particularly in the head and neck region are rare...

OBJECTIVE: Giant cell tumor of bone (GCTB) invades extensively and metastasizes, however, the pathological grade and imaging findings are not accurate predictors of its prognosis. Thus, the aim of this study was to explore the relationships between expression of cluster of differentiation (CD)34 and matrix metalloproteinase-9 (MMP-9) and the biological behavior of GCTB with the hope of identifying predictors of prognosis. METHODS: Sixty-eight patients with GCTBs attending our institution from September 2008 to August 2013 were enrolled in this prospective study and grouped according to tumor location...

Ovarian cancer is the leading cause of mortality due to gynecological malignancy, and vasculogenic mimicry (VM) formation is correlated with poor prognosis. In a previous study, the present authors observed that human chorionic gonadotropin (HCG) could promote VM formation in three-dimensional OVCAR-3 cell cultures. In order to investigate whether HCG could promote VM formation in ovarian cancer in vivo, the role of OVCAR-3 cells overexpressing or depleted of chorionic gonadotropin, beta polypeptide 5 (CGB5, which is the fifth subunit of β-HCG and was identified as the key part of HCG) were injected into nude mice in the present study, while BeWo cells were used as a positive control...

Endothelial progenitor cells (EPCs) are important in tumor angiogenesis. Stromal cell-derived factor-1α (SDF-1α) and its receptor C-X-C chemokine receptor type 4 (CXCR4) are key in stem cell homing. Melittin, a component of bee venom, exerts antitumor activity, however, the underlying mechanisms remain to be elucidated. The present study aimed to assess the effects of melittin on EPCs and angiogenesis in a mouse model of osteosarcoma. UMR‑106 cells and EPCs were treated with various concentrations of melittin and cell viability was determined using the MTT assay...

INTRODUCTION: Fat grafting for breast cancer (BrCa) reconstruction and breast augmentation has become increasingly more popular. A major area of debate and controversy is the effect of adipose-derived stem cells (ASCs) on remnant or undetected BrCa cells. We investigate the in vitro response of BrCa to ASCs in a coculture model with regards to cell migration. METHODS: The study was approved by the institutional review board. BrCa and adipose tissue specimens either from subcutaneous breast tissue or abdominal lipoaspirate were obtained from the same patient...

Adequate hematopoietic progenitor cell (HPC) collection is critical for patients undergoing autologous HPC transplant (AHPCT). Historically, 15 - 30% of patients failed HPC mobilization with granulocyte-colony stimulating factor (G-CSF) alone. Bortezomib, a proteasome inhibitor, has been shown to down regulate very late antigen-4 (VLA-4), an adhesion molecule expressed on HPCs. In this pilot study, bortezomib was administered on days -11 and -8 at a dose of 1.3 mg/m(2) intravenously (IV) or subcutaneously (SQ), followed by G-CSF 10 mcg/kg SQ, on days -4 to -1 prior to HPC collection (Day 1)...

A 72-year-old female presented with dyspepsia for 2 years and an incidental mass in the head of the pancreas on abdominal computed tomography (CT) scan. Patient had multiple negative endoscopic ultrasound guided biopsies. She was followed up for 3 years with serial imaging until an abdominal CT scan showed an increase in size of the pancreatic mass. Physical examination was unremarkable. Laboratory tests including tumor markers were normal. Given the enlarging size of the mass and its impingement on the portal vein, the consensus was to proceed with surgery...

Curcumin may exert a more selective cytotoxic effect in tumor cells with elevated levels of free radicals. Here, we investigated whether curcumin can modulate etoposide action in myeloid leukemia cells and in normal cells of hematopoietic origin. HL-60 cell line, normal myeloid progenitor cluster of differentiation (CD)-34(+) cells, and granulocytes were incubated for 4 or 24 hours at different concentrations of curcumin and/or etoposide. Brown Norway rats with acute myeloid leukemia (BNML) were used to prove the influence of curcumin on etoposide action in vivo...

Leukemia stem cells (LSCs) are hypothesized to be capable of driving the development of leukemia, and are responsible for disease relapse. Antibody therapy targeting cell surface antigens has significantly improved the treatment outcomes of leukemia. Therefore, it is important to identify cell surface markers that are expressed on LSCs, and that are unexpressed or expressed at reduced levels on normal hematopoietic stem cells (HSCs), in order to establish novel therapeutic targets. In the present study, the immunophenotypic characteristics of cluster of differentiation (CD)34(+)CD38(-)lineage (Lin)(-) stem cells were analyzed, and antigen expression levels were compared with the expression of other cell components, using multicolor flow cytometry, in 54 patients with newly diagnosed acute myeloid leukemia (AML) and 11 control patients with immune thrombocytopenia...
