Quantifying treatment preferences and their association with financial toxicity in women with breast cancer

Background The objective of the current study was to understand treatment preferences and their association with financial toxicity in Patient Advocate Foundation clients with breast cancer. Methods This choice‐based conjoint analysis used data from a nationwide sample of women with breast cancer who received assistance from the Patient Advocate Foundation. Choice sets created from 13 attributes of 3 levels each elicited patient preferences and trade‐offs. Latent class analysis segmented respondents into distinct preference archetypes.

Results Of 220 respondents (for a response rate of 10%), the median age was 58 years (interquartile range, 49‐66 years); 28% of respondents were Black, indigenous, or people of color; and approximately 60% had household incomes
