Abstract
Introduction: More adjuvant treatment options are becoming available for hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) early breast cancer (EBC) based on results of clinical trials. This study quantified the importance of different attributes of EBC adjuvant therapies to patients and the benefit-risk tradeoffs patients were willing to make. Methods: = 40). Participants (pts) made 10 choices between pairs of hypothetical treatments described by varying levels of 6 attributes. DCE data were analyzed using a correlated mixed logit model. Relative attribute importance scores captured the impact of each attribute across clinically relevant ranges. Benefit-risk tradeoffs were captured as the minimum improvements in 5-year invasive disease-free survival (iDFS) that pts would require to tolerate increases in therapy-associated adverse event (AE) risks. Results: A total of 866 patients from the USA, France, Spain, Canada, the UK, Germany, South Korea, and Australia completed the DCE (mean age: 57.7 years; 76% postmenopausal; 29% stage I disease, 55% stage II, 16% stage III). Improved 5-year iDFS (75.4-82.7% range; associated with combination regimens [CRs] vs. endocrine therapy [ET] alone) contributed the most to treatment preferences (clinically relevant relative attribute importance: 38.4%), followed by reduced risks of venous thromboembolic events (VTEs) (20.4%), neutropenia (20.3%), and diarrhea (15.0%). Treatment type + duration (3.7%) and fatigue (2.3%) were less important. Pts required the largest improvement in 5-year iDFS (3.9%) to tolerate increased risks of VTE (0.7%-2.5%) or neutropenia (5.6%-46%); willingness to accept tradeoffs depended on the AE. Preference heterogeneity was observed across subgroups, but 5-year iDFS improvement was consistently the most impactful on treatment choice in all subgroups. Conclusion: A multicountry sample of patients most valued adjuvant therapies with higher 5-year iDFS and may therefore prefer CRs over ET alone. The value of CRs depends on their specific safety profiles, and shared decision-making should consider this to select treatment options that align with individual preferences.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
