BACKGROUND: Life expectancy (LE) is essential for triage between aggressive and conservative management for all prostate cancer risk subtypes. We sought to investigate differences in how Black and Hispanic men interpret LE in treatment decision-making.
METHODS: We used targeted crowdsourcing to sample a cohort reflecting sociodemographics of a US prostate cancer population. Subjects completed a conjoint analysis exercise where they iteratively chose between aggressive treatment versus conservative management across levels of 4 tradeoffs-tumor risk (lives saved by aggressive treatment at 5/10/20 year); erectile dysfunction; urinary incontinence; and irritative urinary symptoms-while considering their LE as calculated by the Prostate Cancer Comorbidity Index. Multinomial conditional logistic regression compared odds of choosing aggressive vs. conservative treatment across LEs ranging from 0 to 20 years overall and across racial/ethnic subgroups.
RESULTS: Of 2046 men, 435 (22%) were Black and 230 (11%) were Hispanic. Across all men, the odds of aggressive treatment choice increased by 17% for every 5 years of additional LE (OR = 1.17, 95%CI = 1.12-1.22, p < 0.001). Men were significantly more likely to choose aggressive treatment at LE > 13 y and non-aggressive treatment at LE ≤ 10 y. Among Black men, LE was not associated with treatment choice, as they consistently preferred aggressive treatment across all LE categories. Among Hispanic men, increased LE was associated with a higher likelihood of choosing aggressive treatment, with significant preference for aggressive treatment observed only when LE > 10 years. These patterns remained consistent when further stratified by tumor risk.
CONCLUSIONS: LE had no impact on treatment decisions in Black men, in contrast to other races and ethnicities. Future research is needed to identify reasons for this phenomenon and to inform culturally relevant approaches to communicating competing mortality risks.
