Anastrozole is a comparatively simple, achiral benzyltriazole derivative, 2,2'-[5-(1H-1,2,4-triazol-1-ylmethyl)-1,3-phenylene]bis(2-++ +methylpropiononitrile), that inhibits human placental aromatase with an IC50 of 15 nM and elicits maximal activity in vivo in rats (inhibition of ovulation and androstenedione-induced uterine hypertrophy) and monkeys(More)
Little information is available regarding the management of BRCA-related breast cancer in Ireland. A cancer genetics programme was initiated in 1992 at our institution to provide counselling and expert management for those with cancers resulting from inherited predisposition. We examined a cohort of BRCA mutation-carriers treated at a single institution(More)
PURPOSE Young age and extensive intraductal component (EIC) histology have been shown to be associated with increased local recurrence in women treated with breast conservation therapy. This study was conducted to determine if the status of the lumpectomy specimen margin consistently predicted for residual tumor burden risk irrespective of these variables.(More)
AIMS Obesity is associated with both an increased risk of postmenopausal breast cancer and increased mortality rates. The mechanism is unclear, and central (visceral) obesity, insulin resistance, altered sex steroids and altered adipokines are mooted as possible factors. These features may cluster in the so-called metabolic syndrome. The relevance of(More)
PURPOSE To investigate the incidence of and variables associated with clinically evident fat necrosis in women treated on a protocol of high-dose-rate (HDR) brachytherapy alone without external-beam whole-breast irradiation for early-stage breast carcinoma. METHODS AND MATERIALS From 6/1997 until 8/1999, 30 women diagnosed with Stage I or II breast(More)
The nasal airway is a common route for oxygen delivery to hypoxemic patients, and it has been advocated as a suitable route for intermittent positive pressure ventilation to patients in respiratory failure. There is, however, conflicting evidence on the question of whether nasal airflow has a stimulant or a depressant effect on ventilation. We therefore(More)
Many patients with newly diagnosed breast cancer undergo multiple staging investigations. We aimed to assess the use and yield of baseline diagnostic imaging in early-stage breast cancer. A review of all patients diagnosed with breast cancer over five years at a single institution was carried out. 781 patients were included. At diagnosis 266 (34%) patients(More)
Obesity and its associated metabolic syndrome (MetS) are recognized risk factors for breast cancer. The molecular basis for this association remains largely unknown. Adipokines, in particular leptin and adiponectin, are thought to form part of the mechanism linking obesity with cancer through their altered expression/production either systemically(More)
