Description of intervention(s) / exposure
To prospectively describe real-world clinicopathologic presentation and treatment selection in patients with newly or recently diagnosed HR+ve, HER2-ve Advanced Breast Cancer in Australia of approximately 300 patients from 10-15 sites. Recruitment is expected to take place over a 3 year period. The entire study duration is 4 years, with an estimated median patient follow up of 2.5 years.
There is no active participation of patients required as data will be collected from medical records. Information collected would include details about the presentation and course of disease, the type and sequence of therapies and the outcomes for each patient. The data would be collected retrospectively from January 2020 onward and prospectively for new patients and data.

Statistical methods / analysis
Kaplan-Meier survival curves will be defined from survival data and constructed using SAS® software (SAS Institute Inc., Cary, NC, USA) to compare clinical outcomes across different subgroups. The stratified log rank test will be used to compare survival curves between different groups of participants. Comparison of specific variables will be performed using the Chi square method. P-values of <0.05 will be considered statistically significant. Due to the non-randomised nature of such comparisons, propensity score techniques will be used to balance comparison groups according to baseline factors.
