Advanced Breast Cancer Fourth International Consensus Conference (ABC4)

02 November 2017 — 04 November 2017 The European School of Oncology (ESO)

Media have until 15 October to register online to attend the Advanced Breast Cancer Fourth International Consensus Conference (ABC4) in Lisbon, Portugal, Thursday 2 to Saturday 4 November 2017. After 15 October, you will need to register onsite when you arrive in Lisbon. Registration for bona fide journalists is free.

A press conference will take place at 12.30 hrs GMT on Thursday 2 November, chaired by Professor Fatima Cardoso, the co-ordinating chair of ABC4. Further details will be sent at the end of October.

The International Consensus Conference for Advanced Breast Cancer (ABC) has established itself as a major international conference. Despite advances in the treatment of early breast cancer in the past decades, patients with advanced breast cancer face a poor prognosis and are under-served and largely forgotten [1]. There are no reliable figures for the numbers of women (and men) living with advanced breast cancer. However, there are over 1.7 million new cases of breast cancer a year in the world and 0.5 million deaths. About 5-10% of cases are either locally advanced or have spread to other parts of the body at diagnosis, and these figures can reach 80% in developing countries. About a third of all early breast cancer cases will become metastatic even with the best care, and the average overall survival for these patients is around two to three years.

Over 1,200 participants from approximately 80 countries around the world will attend ABC4 in Lisbon this November, including health professionals and patient advocates. Sessions will include those on affordability and access to care, new treatments, new technologies and techniques, survivorship, supportive and palliative care, and patient advocacy.

ABC Global Alliance

ABC4 will be followed by the first meeting of the ABC Global Alliance, established by the European School of Oncology. The Alliance is for people and organisations, interested in collaborating on common projects relating to ABC around the world, to develop, promote and support tangible improvements that will ultimately create awareness and actions that will improve and extend the lives of patients living with ABC worldwide. The meeting will take place in the congress centre, in the afternoon of 4 November and morning of 5 November. Further information is available at

[1] Advanced breast cancer is defined as cancer that has spread beyond the site of the first (primary) tumour to other sites either within the same breast such as the skin, chest wall and some lymph nodes (locally advanced) or other parts of the body (metastatic cancer). The primary aim of ABC4 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. At the end of the 2017 conference, a group of world renowned breast cancer experts will agree on a new set of guidelines for the best treatment of ABC patients and these will be published subsequently in peer-reviewed journals. These guidelines constitute the European and International guidelines for the management of these diseases and are widely used all over the world.
