policy implementation. Determining the public’s risk perception is an essential step inevaluating overall risk, especially with regard to sensitive projects. This study aims toinform Quebec’s public decision-makers about the socio-political issues surroundinglarge-scale projects. In addition to measuring risk perception, the study evaluates confidencein public project management and in the information related to the project,each of which has an influence on risk perception. To evaluate these variables, we havedesigned a groundbreaking province-wide survey. We probe public opinion and riskperception on projects and issues related to the environment, technology, health andthe economy. A survey was conducted in June 2011. This presentation will analyze theresponses of 1130 representative people living in Quebec. We first present descriptiveresults (risks categories that are of greatest concern, top 3 of riskiest projects, etc..)and then expose differences in responses in relation to different socio-demographiccriteria (age, sex, region, language, education, income, employment, etc.). Given thelarge spectrum of our inquiry, our results will be a valuable reference for the Quebecgovernment and public decision-makers. Our findings may also incite governments toconsider communications as an important tool of risk management, leading them todraw from our study when announcing a big decision or developing a communicationplan for a new project.P.104 Demichelis SO, Cermignani L, Segal-Eiras A, Giacomi N, Croce MV;sandrademichelis@yahoo.comNational University of La Plata, University J.F. Kennedy of Argentina, Buenos AiresBREASTFEEDING AND NUMBER OF CHILDREN ARE RELEVANTRISK FACTORS IN BREAST CANCER PATIENTS FROM AN ARGEN-TINE COASTAL MIDCLASS POPULATIONBackground: In Argentina, it has been estimated that there are 17.000 new casesof breast cancer diagnosed each year; this tumor localization is the commonestcause of cancer death among women reaching 5.400 deaths per year, the second rateof mortality in Latin America. Purpose: to analyze the relationship among differentrisk and prognostic factors in invasive breast cancer patients in order to highlighttheir possible clinical relevance. Patients and methods: 360 patients from La Plataarea (Buenos Aires Province, Argentina) with invasive breast cancer were included.Risk factors were age, number of children, breast feeding, menopausal status andmenarche age while prognostic factors were histological type and grade, tumor size,number of metastatic nodes, disease stage, mitotic figure counts, Nottingham PrognosticIndex (NPI), vascular invasion (VI) and estrogen and progesterone receptors.Statistical analysis: Multiple and simple correlation, frequency analysis and ANOVAwere performed (p
