RESUMO
This manuscript describes the Advanced Breast Cancer (ABC) international consensus guidelines updated at the last two ABC international consensus conferences (ABC 6 in 2021, virtual, and ABC 7 in 2023, in Lisbon, Portugal), organized by the ABC Global Alliance. It provides the main recommendations on how to best manage patients with advanced breast cancer (inoperable locally advanced or metastatic), of all breast cancer subtypes, as well as palliative and supportive care. These guidelines are based on available evidence or on expert opinion when a higher level of evidence is lacking. Each guideline is accompanied by the level of evidence (LoE), grade of recommendation (GoR) and percentage of consensus reached at the consensus conferences. Updated diagnostic and treatment algorithms are also provided. The guidelines represent the best management options for patients living with ABC globally, assuming accessibility to all available therapies. Their adaptation (i.e. resource-stratified guidelines) is often needed in settings where access to care is limited.
RESUMO
In January 2016, the Metastatic Breast Cancer Alliance (the Alliance) convened a think tank of stakeholders from academia, government, industry, and patient advocacy to discuss gaps and opportunities in clinical and translational research in metastatic breast cancer. Priorities that emerged from the meeting included the following: the need for innovative preclinical model systems to study metastatic disease; increased sharing of resources and data; collaboration across cancer care teams and scientists; biorepositories for studies to identify biomarkers for treatment response; creation of patient registries to increase access to clinical trials and tissue procurement; and redesign of clinical trials in metastatic breast cancer.
