Gastrointestinal stromal tumours (GIST) are the most common mesenchymal tumours of the digestive tract. Most gastrointestinal soft tissue neoplasms, previously classified as leiomyomas, schwannomas, leiomyoblastomas or leiomyosarcomas, are today classified as GIST on the basis of molecular and immunohistological features. They originate from(More)
PURPOSE Androgens stimulate the production of hypoxia-inducible factor (HIF1α) and ultimately vascular endothelial growth factor (VEGF-A). Additionally, epithelial growth factor (EGF) mediates HIF1α production. Carbonic anhydrase IX (CAIX) expression is associated with tumor cell hypoxia in a variety of malignancies. This study assesses the prognostic(More)
The rupture of an intra-abdominal testicular neoplasm is a rare cause of acute abdomen and massive intra-abdominal haemorrhage. We report the case of a 70-year-old male presenting a massive intra-abdominal bleeding caused by a Leydig cell tumour in an undescended testis. The clinical details and pathology of this rare testicular tumour are discussed.
PURPOSE The feasibility and safety of left-sided colorectal procedures with avoidance of mechanical bowel preparation has recently been demonstrated. Moreover, mechanical preparation has been associated with an increased risk for abdominal septic complications, including anastomotic leakage. This study was designed to determine whether mechanical bowel(More)
Adenocarcinoid of the appendix is an infrequent tumor with histologic features of both adenocarcinoma and carcinoid tumor. Although its malignant potential remains unclear, adenocarcinoids seem to be biologically more aggressive than conventional carcinoids. The aim of this study was to analyze long-term results of surgical treatment for appendiceal(More)
BACKGROUND Sentinel lymph node (SLN) biopsy plays a major role in the surgical management of primary breast cancer. The aim of this study was to assess the diagnostic accuracy of the assessment of axillary frozen sections of SLNs for micrometastasis diagnosis. PATIENTS AND METHODS This study focused on 278 SLNs from 149 patients. Each lymph node was fully(More)
Recent findings have attested the protective effects of erythropoietin (EPO) in ischemically challenged organs. We therefore aimed at elaborating the underlying mechanism of EPO-mediated protection in musculocutaneous tissue undergoing persistent ischemia after acute injury. Mice were assigned to five experimental groups equipped with a randomly perfused(More)
Twenty-seven endometrioid stromal sarcomas of the ovary from patients 38 to 76 (mean 56) years of age are reported. The tumors were unilateral in 20 cases and bilateral in 7. They were solid (9), solid and cystic (9), or predominantly cystic (6) when this information was known and ranged from 1 to 20 (mean 9.5) cm. The solid areas typically had a tan-yellow(More)
Epstein-Barr virus (EBV) is associated with several types of cancers including Hodgkin's lymphoma (HL) and nasopharyngeal carcinoma (NPC). EBV-encoded latent membrane protein 1 (LMP1), a multifunctional oncoprotein, is a powerful activator of the transcription factor NF-κB, a property that is essential for EBV-transformed lymphoblastoid cell survival.(More)
OBJECTIVE The challenges of imaging posterior deeply infiltrating endometriosis with MRI are to image a small anatomic area encompassing several thin fibromuscular anatomic structures such as uterosacral ligaments, and the vaginal and rectal walls; and to image endometriotic lesions, which are fibromuscular structures and have an MRI signal intensity very(More)
