Patients Undergoing Radiation Therapy Are at Risk of Financial Toxicity: A Patient-based Prospective Survey Study

Little is known about the financial burden experienced by patients receiving radiation therapy. Furthermore, currently, no financial toxicity screening tools have been validated for use in radiation oncology.

Physician surveys were used to gauge provider understanding of treatment costs and their willingness to adopt the use of financial toxicity screening tools. Post-treatment patient surveys were used to investigate the covariates of treatment-induced financial risk.

Of the 210 radiation oncologists who completed our survey, 53% reported being "very concerned" with treatment-related costs negatively affecting their patients, and 80% believed that a financial toxicity screening tool would be useful in practice. An analysis of patient surveys using logistic regression found age and cancer site to be the most important variables associated with financial toxicity. Thirty-four patients (22%) experienced financial toxicity related to treatment. The financial toxicities experienced were loss of job (28%), loss of income (24%), difficulty paying their rent or mortgage (20%), difficulty paying for transportation (15%), and difficulty paying for meals (13%).

Financial toxicity is an important measure for patients and providers and is experienced by approximately one quarter of patients. Further studies to improve models to predict financial toxicity and how financial toxicity is related to patient outcomes and quality of life are warranted.
