Diagnosis of a clinical entity like pregnancy associated breast cancer (PABC) is as demanding and challenging as its rarity. Increasing incidence and controversy that exists in the literature upon prognosis, tumor aggressiveness and underlying mechanisms, highlight the importance of optimizing the diagnostic strategy in women with PABC. Adjustment of(More)
BACKGROUND Primary hepatic neuroendocrine tumor with exophytic growth is a unique entity. CASE A 74-year-old man presented to our hospital with abdominal discomfort. Diagnostic imaging procedures revealed a 15 x 10-cm mass in the liver with exophytic growth. The tumor was adjacent to the stomach, and clinical suspicion of gastrointestinal stromal tumor of(More)
Peroxisome Proliferator Activated Receptor-gamma (PPAR-gamma) is a ligand-activated transcription factor belonging to the steroid receptor superfamily. It is a key regulator of adipogenic differentiation and glucose homeostasis, the ligands of which have also been demonstrated to induce differentiation in human breast, lung and colon cancer cell lines. In(More)
Peroxisome proliferator-activated receptor-γ (PPAR-γ) has currently been considered as molecular target for the treatment of human metabolic disorders. PPAR-γ has also been implicated in the pathogenesis and progression of several types of cancer, being associated with cell differentiation, growth and apoptosis. The present study aimed to evaluate the(More)
The role of vascular endothelial growth factor (VEGF) in tumor angiogenesis is well characterized; nevertheless, it is also a key element in promoting tumor evasion of the immune system by downregulating dendritic cell maturation and thus T cell activation. We sought to investigate the possible direct effect of VEGF on T cell activation and through which(More)
OBJECTIVE GHRH is secreted by the hypothalamus and, upon binding to specific GHRH receptors in the pituitary, stimulates growth hormone (GH) production and release from the pituitary. In addition to this neuroendocrine action, accumulated evidence implies additional roles for GHRH in carcinogenesis in non-pituitary tissues. In vitro and in vivo studies have(More)
The morphological evaluation of cytological specimens from body cavity fluids presents difficulties in the differential diagnosis between benign reactive mesothelial (RM) cells and adenocarcinoma (AC) or malignant mesothelioma (MM). The aim of our study was to investigate whether a panel of five different antibodies can offer reliable markers in the(More)
Focal adhesion kinase (FAK), a non-receptor tyrosine kinase protein, acts as an early modulator of integrin signaling cascade, regulating basic cellular functions. In transformed cells, unopposed FAK signaling has been considered to promote tumor growth, progression and metastasis. The aim of this study was to assess the clinical significance of FAK(More)
INTRODUCTION The presence of CD3(+) tumor-infiltrating lymphocytes (TILs) has been found to correlate with improved survival in epithelial ovarian cancer, but the association of TIL subpopulations with clinical outcome remains controversial. We performed a prospective analysis of TIL subpopulations from patients with epithelial ovarian cancer and their(More)
OBJECTIVES To investigate, in a retrospective study, the expression of erythropoietin (Epo) in human renal cell carcinoma (RCC) and its correlation with overall survival, as Epo (an haematopoietic cytokine that regulates the production of red blood cells), with its receptor, was recently localized in non-haematopoietic tissues, e.g. liver, uterus, central(More)
