ESO-ESMO 2nd International Consensus Guidelines for Advanced Breast Cancer (ABC2)

This is a clinical practice guideline for the treatment of patients with advanced breast cancer (ABC). Treatment options are discussed for inoperable locally advanced breast cancer (LABC), both inflammatory and non-inflammatory; and metastatic breast cancer (MBC), with recommendations specific to site of metastasis. Treatment recommendations are further stratified by cancer subtype (tumour status) and by specific populations including patients with BRCA-associated triple-negative or endocrine-resistant MBC and male patients with ABC.
