Dear Colleagues,

The International Consensus Conference for Advanced Breast Cancer (ABC) has established itself as a major international breast cancer conference. Its primary aim is the development of international consensus guidelines for the management of ABC patients. These guidelines are based on the most up-to-date evidence and can be used to guide treatment decision making in many different health care settings globally, with the necessary adaptations due to different access to care.

The last meeting, which took place in Lisbon, Portugal in November 2015, brought together over 1.200 participants from 84 countries around the world, including health professionals, patient advocates and journalists.

We believe that health professionals working closely together with patient advocates and with the strong support of media can raise awareness about the needs and challenges faced by this traditionally underserved and forgotten group of patients. ABC also aims to identify research priorities based on the most important areas of unmet need, analyse and discuss available data to provide the most accurate management recommendations, as well as influence policy makers and funding bodies and ultimately improve standards of care, survival and quality of life. Research and education, with accurate usage of available knowledge, throughout the world, are key to achieve these goals.

ABC guidelines are jointly developed by ESO (European School of Oncology) and ESMO (European Society of Medical Oncology) and guidelines or ABC conferences have been endorsed and supported by several other international oncology organizations such as EUSOMA (European Society of Breast Cancer Specialists), ESTRO (European Society of Radiation Oncology), ESGO (European Society of Gynaecological Oncology), UICC (Union International Contre le Cancer), SIS (Senologic International Society) / ISS (International School of Senology), FLAM (Federacion Latino-Americana de Mastologia), OECI (Organization of European Cancer Institutes), Susan G. Komen
and BCRF (Breast Cancer Research Foundation), and have official representation from ASCO.
The recent creation of the Global MBC Alliance, will also provide a much needed platform for the development of important projects, aiming to strongly impact on the survival and quality of life of advanced breast cancer patients.

It is therefore with great enthusiasm that we invite you to attend the Advanced Breast Cancer Fourth ESO-ESMO International Consensus Conference (ABC4) that will take place in Lisbon, Portugal, on 2-4 November 2017.

Fatima Cardoso,
Coordinating Chair
