BACKGROUND Axillary lymph node status has been the most important prognostic factor in operable breast carcinoma, but it does not fully account for the varied disease outcome. More accurate prognostic indicators would help in selection of patients at high risk for disease recurrence and death who are candidates for systemic adjuvant therapy. Our recent(More)
The epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein whose expression is important in the regulation of breast cancer cell growth. The relationship between EGFR status (determined by an immunocytochemical assay) and various prognostic factors was investigated in 164 primary breast cancers. Overall 56% of tumours were EGFR-positive and(More)
PURPOSE Experimental studies suggest that angiogenesis is necessary for breast cancer progression and metastasis and that it may play a role in responsiveness to some chemotherapeutic agents and to tamoxifen. To investigate whether angiogenesis predicts the clinical outcome of patients with node-positive breast cancer, we determined intratumoral microvessel(More)
In operable breast cancer, cell kinetics can be utilized in the prediction of the clinical outcome of patients. The discovery of monoclonal antibodies recognizing antigens related to cell proliferation has permitted the assessment of cell kinetics by rapid and practical immunocytochemical methods. It is claimed that the Ki-67 mouse monoclonal antibody(More)
BACKGROUND Endothelin-1 (ET-1) is able to determine functional and structural renal alterations and plasma levels of this vasoconstrictor peptide are increased in diabetic patients. In a selected group of type 2 normotensive diabetic patients with microalbuminuria, we investigated circulating ET-1 levels compared to a control group and verified whether(More)
PURPOSE A study was undertaken to define the prognostic value of the expression of the c-erbB-2 oncoprotein in a series of breast cancer patients when compared by multivariate analysis with expression of the epidermal growth factor receptor (EGFR), DNA ploidy, and conventional clinicopathologic features. PATIENTS AND METHODS Prognostic indicators were(More)
Hyperhomocysteinemia is widely recognised as an emerging risk factor of endothelial dysfunction and vascular damage. In this study we wanted to verify if it, when associated to arterial hypertension--traditional risk factor--represents a higher added risk of organ damage during menopause, which is a condition connected to a higher incidence of(More)
The authors report a typical case of JHF. The complete review of the literature shows that no more than 20 cases have been so far described. The clinical, pathological and electron microscopic features are stressed and the main clinical and pathological differential diagnoses are considered. The disease, formerly thought to be due to an abnormal composition(More)
