The financial burden and distress of patients with cancer: Understanding and stepping‐up action on the financial toxicity of cancer treatment
Open accessAbstract
“Financial toxicity” has now become a familiar term used in the discussion of cancer drugs, and it is gaining traction in the literature given the high price of newer classes of therapies. However, as a phenomenon in the contemporary treatment and care of people with cancer, financial toxicity is not fully understood, with the discussion on mitigation mainly geared toward interventions at the health system level. Although important, health policy prescriptions take time before their intended results manifest, if they are implemented at all. They require corresponding strategies at the individual patient level. In this review, the authors discuss the nature of financial toxicity, defined as the objective financial burden and subjective financial distress of patients with cancer, as a result of treatments using innovative drugs and concomitant health services. They discuss coping with financial toxicity by patients and how maladaptive coping leads to poor health and nonhealth outcomes. They cover management strategies for oncologists, including having the difficult and urgent conversation about the cost and value of cancer treatment, availability of and access to resources, and assessment of financial toxicity as part of supportive care in the provision of comprehensive cancer care.

In “Evidence About Financial Burden on and Financial Distress by Patients With Cancer” (page unavailable), the review reports that higher psychological distress was significantly associated with financial toxicity. “Cancer Drugs and Financial Toxicity” discusses financial distress alongside anxiety, but does not report an association between greater financial toxicity and increased anxiety specifically. (LLM, conf=0.83)
Experimental — accuracy not yet measuredAlthough these sacrifices were perceived as meaningful demonstrations of love and familial commitment, they also risked household financial instability, anxiety about accumulated debt, and vulnerability to future crises.

From The burdens, coping strategies, and unmet needs of family caregivers of Chinese patients with lymphoma receiving commercial CAR-T-cell therapy: A qualitative study (2026) · cites this paper as [59]
In “A Household Economic Perspective on Financial Toxicity” (page unavailable), the paper describes families using savings, selling assets, and borrowing to cope with cancer costs, and says accumulated debt affects household welfare. It also describes financial distress and worry about coping strategies. It does not describe these sacrifices as demonstrations of love or familial commitment, or specifically discuss vulnerability to future crises. (LLM, conf=0.85)
Experimental — accuracy not yet measuredThe decision to change the attention control from finances to nutrition was made because of increasing acknowledgment of the relevance and salience of financial toxicity among cancer survivors.
“This decision was made because of the increasing acknowledgment of the relevance and salience of financial toxicity experienced among cancer survivors [54]”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
