Development and validation of a clinical prediction rule to identify suspected breast cancer: a prospective cohort study.

Background: The number of primary care referrals of women with breast symptoms to symptomatic breast units (SBUs) has increased exponentially in the past decade in Ireland. The aim of this study is to develop and validate a clinical prediction rule (CPR) to identify women with breast cancer so that a more evidence based approach to referral from primary care to these SBUs can be developed.

Methods: We analysed routine data from a prospective cohort of consecutive women reviewed at a SBU with breast symptoms.

COX inhibitors modulate bFGF-induced cell survival in MCF-7 breast cancer cells.

Basic fibroblast growth factor (bFGF) serves as a modulator of survival in breast cancer cells. The mechanisms by which bFGF transduces the anti-apoptotic signal and interacts with COX inhibitors were investigated. bFGF reduced apoptosis in MCF-7 breast cancer cells and up-regulated the expression of mitocondrial Bcl-2, whereas COX inhibitors meloxicam (selective COX-2) and aspirin (non-selective), induced apoptosis.
