OBJECTIVE The aim of this review is to study natural history, presentation, treatment and prognosis of head and neck liposarcomas. METHODS We carry a retrospective study about 15 patients diagnosed and treated in our department between 1969 and 2001. Therapeutic modalities included surgery, radiotherapy and chemotherapy. RESULTS Tumors were mostly(More)
Matrix metalloproteinases (MMPs) are proteolytic enzymes that play important roles in tumor invasion and metastasis by degrading extracellular matrix components. Genetic variations in promoter regions of MMP genes, affecting their expression, have been associated with susceptibility to cancers. The aim of this study was to investigate the susceptibility and(More)
Le mélanome muqueux primitif de la fosse nasale est une tumeur maligne très agressive, rare, constituant 1% de l’ensemble des mélanomes. Sa symptomatologie est non spécifique et son diagnostic est anatomo-pathologique, appuyé par l’immunohistochimie. Son traitement est essentiellement chirurgical basé sur une résection large de la tumeur. Le pronostic est(More)
Tissue inhibitors of metalloproteinases (TIMPs) appear to affect many aspects of cancer biology, playing a crucial role in cell signaling by regulating cell growth, apoptosis, invasion, metastasis, angiogenesis, and genomic instability. In the present study, we investigate whether TIMP-2 SNP, TIMP-2 mRNAs, and TIMP-2 protein is associated with(More)
Leiomyosarcoma (LMS) of inferior vena cava is a rare and aggressive tumor, arising from the smooth muscle cells in the vessel wall. A large complete surgical resection is the essential treatment. The need of vascular reconstruction is not always mandatory. It's above all to understand the place of the reconstruction with artificial vascular patch(More)
Matrix metalloproteinase-2 (gelatinase A) is a well-known mediator of cancer metastasis, but it is also thought to be involved in several aspects of cancer development, including cell growth and inflammation. In the present study, we investigate whether MMP-2 SNP, MMP-2 mRNAs, and MMP-2 protein are associated with the susceptibility to colorectal cancer in(More)
