Hearing/vestibular dysfunction and longitudinal changes in psychosocial well-being among breast cancer survivors.

12084 Background: Breast cancer treatment, in some cases, can cause hearing/vestibular dysfunction and negatively affect patients’ quality of life. The breast cancer survivor population is both growing and aging. Despite evidence that other cancer survivors have higher rates of hearing/vestibular problems than the general population, little is unknown about the impact of hearing/vestibular dysfunction on long-term changes in psychosocial well-being (PSWB) among breast cancer survivors. Methods: We surveyed the Chicago Multiethnic Epidemiologic Breast Cancer Cohort regarding whether patients had ever been told by a doctor that they had tinnitus, hearing loss, and/or vertigo between July and September 2023. PSWB was assessed repeatedly using the 10-item PROMIS on psychological distress/social isolation in 2020, 2021, 2022, and 2025. Total scores range from 0 to 40, with higher scores reflecting better PSWB. We fit separate linear mixed-effects models for hearing/vestibular dysfunction, controlling for age, race/ethnicity, marital status, income, insurance, comorbidity, AJCC stage, and treatment modality. Adjusted coefficients ( β ) and 95% CIs were calculated. Results: 1,466 breast cancer survivors were included: the mean age at survey was 63.5 years (SD 11.7); 69.6% identified as White, 22.6% as Black, 3.7% as Asian or Pacific Islander, and 3.6% as Hispanic. Overall, 16.5%, 17.4%, and 8.6% had tinnitus, hearing loss, and vertigo, respectively. The distribution of PSWB scores and trend over time are presented in the table. Survivors with hearing/vestibular dysfunction had lower mean scores than those without. After covariate adjustment, tinnitus ( β –1.12; 95% CI –1.93, –0.30), hearing loss ( β –1.12; 95% CI –1.93, –0.30), and vertigo ( β –1.34; 95% CI –2.44, –0.24) were associated with significantly lower PSWB scores. In all subgroups, the PSWB score increased significantly over the years. Furthermore, Hispanic ethnicity, Medicaid, and being single were correlated with lower scores; whereas higher income levels were associated with higher scores. Conclusions: In this diverse cohort, breast cancer survivors with hearing/vestibular dysfunction experienced suboptimal PSWB over the study period. PSWB also varied by socioeconomic status. Oncology programs should consider screening for hearing/vestibular dysfunction and unmet sensory healthcare needs to improve PSWB and quality of life among breast cancer survivors.
