Financial toxicity is a growing concern due to its considerable effects on medical adherence, quality of life, and mortality. The cost associated with breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is substantial from diagnosis to treatment, including adjuvant therapy and surgery. This study aims to assess the prevalence of financial toxicity in BIA-ALCL patients. We performed a cross-sectional, survey-based study on women with confirmed cases of BIA-ALCL from December 2019 to March 2023. The primary study outcomes were financial toxicity measured by Comprehensive Score for Financial Toxicity (COST) score and patient-reported financial burden measured by the responses to the Evaluation of the Financial Impact of BIA-ALCL survey. Lower COST scores signify higher financial toxicity. Responses were linked to patient data extracted from the medical records. Thirty-two women treated for confirmed BIA-ALCL were included. Patients were all White and were diagnosed at a median age of 51 years (range, 41-65 years). The mean COST score was 27.9 ± 2.23. Lower COST scores were associated with receipt of radiotherapy ( P = 0.033), exceeding credit card limits ( P = 0.036), living paycheck to paycheck ( P = 0.00027), requiring financial support from friends and family ( P = 0.00044), and instability in household finances ( P = 0.034). Financial toxicity is prevalent in BIA-ALCL patients and has a substantial impact on patient reported burden. Insurance denial is frequent for patients with a prior history of cosmetic augmentation. Risk assessments and cost discussions should occur throughout the care continuum to minimize financial burden.
