Characterizing the logistic toxicity of cancer treatment in non–English speaking population.

230Background: The burden of symptoms and financial toxicity are well-documented adverse effects of cancer treatments. Recently, logistic toxicity has emerged, referring to the detrimental impact of logistical demands associated with cancer treatment on patient well-being. For non- English speaking patients, language barriers can affect their treatment experience, increasing logistic burdens. Methods: Between September 2024 and May 2025, semi-structured qualitative interviews were conducted with 21 low English proficiency (LEP)/non-English speaking adults with cancer. The interviews explored logistic challenges faced due to LEP and its impact on patients' cancer care experience. Transcripts were analyzed using an inductive thematic analysis approach. Results: Of the 39 identified eligible individuals, 26 provided consent, and 21 (81%) completed the interview. The most common primary language of the participants was Spanish (9, 43%), followed by Somali (3, 14%), Arabic and Korean (2, 9%), and Amharic, Mandarin, Hmong, Russian, and Vietnamese (1, 5%). Seven major themes emerged regarding the logistic burdens of cancer care: (1) communication challenges, (2) navigating healthcare systems, (3) emotional distress from diagnosis and communication barriers, (4) financial toxicity, (5) transportation challenges, (6) adverse treatment effects, and (7) concerns about the political climate and its impact on resources. Conclusions: The increase in non-English languages in the U.S. highlights the need to understand the unique challenges faced by these patients. This study identified logistic toxicity themes consistent with previous research, while also revealing unique challenges. Further research is necessary to explore strategies to mitigate logistic burdens among those with LEP.
