Abstract PO-189: Precision medicine for African breast cancer: Bringing African researchers together to study African breast cancer

Abstract

Introduction In sub-Saharan Africa, breast cancer (BC) is the leading cancer in women and the second cause of cancer mortality. In order to reduce the burden of BC in women with African ancestry there is a need for a structured, coordinated effort to address gaps in our understanding of the factors associated with the disease that influence tumor initiation, progression, and outcomes. To address this need ‘Precision Medicine for African Breast Cancer (PMABC)’ a comprehensive partnership housed at the Henry Ford Cancer Institute was created with the aim of bringing together African researchers to study African BC. We are currently composed of nine leading institutions spanning West and East Africa and two institutions in the United States. Objectives The broad aim of PMABC is to bring together researchers and institutions across sub-Saharan Africa to partner with foreign institutions and funding agencies to study and identify new and improved methods of screening, diagnosing, and treating BC in Africans to improve the overall outcome. Among the aims of PMABC are: • Registry: Create a national BC registry building on data from participating institutions which comprise at least 80% of all BC cases seen in the respective country • Standardization of pathology protocol and reporting: harmonize the pathology reporting scheme and ensure its conformity to international standards Standardization of treatment protocols: Study and compare treatment protocols with international standards and make recommendations • Biorepository: Create a national repository of patient samples to be used in genetic and biological studies • Study African tumor biology: Build the capacity to be able to study African tumors locally and participate in clinical trials • Patient follow up and survival studies: study and obtain data on patient outcomes Achievements We currently have ethical approval and have begun work in nine institutions across West and East Africa. • Creation of a national database in Ghana that currently consists of over 7000 patients. The data is being analyzed to determine risk factors and the distribution of BC by subtypes • We are setting up two research labs in Ghana to train local researchers for basic and translational research • We have a biorepository of over 2000 patient samples that is available for collaborative studies • We have developed tumor models from continental African breast tumors • Building partnership with international organizations, pharmaceutical companies, and funding agencies to study African BC Conclusion PMABC serves as an umbrella institution to coordinate the work between these researchers and to provide resources for the institutions to provide a high level of BC research and treatment. We are aiming to partner with countries across Africa to translate the model created by PMABC in order fulfill the need for further BC research and standardization of data collection and treatment. PMABC is made possible because of the dedication and passion of our collaborating researchers. Citation Format: Sabrina I.
