Willingness of Women with Early Estrogen Receptor–Positive Breast Cancer to Take Adjuvant CDK4/6 Inhibitors
Bibliographic record
Abstract
Background: The steady decline in breast cancer (bca) mortality has come at the cost of increasingly toxic and expensive adjuvant therapies. Trials evaluating the addition of 2 or 3 years of cyclin-dependent kinase 4/6 (cdk4/6) inhibitors to adjuvant endocrine therapy (et) are ongoing, but the willingness of patients to take such additional therapy is unknown. Methods: We surveyed 100 consecutive postmenopausal women with nonmetastatic estrogen receptor-positive bca who had initiated adjuvant et within the preceding 2 years. Participants were asked about perceived recurrence risk, bca worry, and overall health. They were then asked about their willingness to accept 2 years of treatment with an additional oral drug that would reduce recurrence by 40% for a range of baseline recurrence risks in 2 hypothetical scenarios. Results: Mean age of the 99 evaluable participants was 61.7 years. In the scenario with no drug toxicity, 85% of respondents were likely to accept the new drug for a reduction in recurrence to 30% from 50%, but only 49% would take the drug if risk was reduced to 3% from 5%. In a scenario with drug-induced fatigue, the corresponding drug acceptance rates were 55% and 39% respectively. For the second scenario, bca worry was correlated with increased willingness to take the drug, even for only a 2% absolute reduction in recurrence risk. Conclusions: The willingness of patients with estrogen receptor-positive bca to take an adjuvant cdk4/6 inhibitor will greatly depend on the expected benefit and toxicities described to them as well as on worry about bca recurrence.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
