Benefit-risk trade-offs in treatment choice in advanced HER2 negative breast cancer: patient and oncologist perspectives.

Abstract

Aim: To evaluate which treatment attributes US patients and oncologists prioritize in HER2 negative advanced breast cancer (ABC). Methods: Preferences were assessed via a discrete choice experiment. Also, treatment goal statements were rated on an agreement scale. Results: Patients (n=169) most valued improving overall survival (OS), followed by improving nausea and neuropathy. Oncologists (n=117) most valued improving OS, followed by neuropathy and progression-free survival. Regarding treatment goals, oncologists (67%) perceived that patients are more focused on efficacy than quality of life; fewer patients (29%) agreed with this statement; 81% of oncologists and 51% of patients agreed that patients prefer oral treatment. Conclusion: Patients and oncologists were willing to accept increases in toxicities in exchange for efficacy improvements in HER2 negative ABC.
