Financial Toxicity in Radiation Oncology: Impact for Our Patients and for Practicing Radiation Oncologists.

With rising costs of diagnosis, treatment, and survivorship, financial burdens on patients with cancer and negative effects from high costs, called financial toxicity (FT), are growing. Research suggests that FT may be experienced by more than half of working-age cancer survivors and a similar proportion may incur debt or avoid recommended prescription medications due to treatment costs. As FT can lead to worse physical, psychological, financial, and survival outcomes, there is a discrete need to identify research gaps around this issue that constrain the development and implementation of effective screening and innovative care delivery interventions. Prior research, including within a radiation oncology-specific context, has sought to identify the scope of FT among patients with cancer, develop assessment tools to evaluate patient risk, quantify financial sacrifices, and qualify care compromises that occur when cancer care is unaffordable. FT is a multifactorial problem and potential solutions should be pursued at all levels of the health care system (patient-provider, institutional, and systemic) with specific regard for patients' individual/local contexts. Solutions may include selecting alternative treatment schedules, discussing financial concerns with patients, providing financial navigation services, low-cost transportation options, and system-wide health policy shifts. This review summarizes existing FT research, describes tools developed to measure FT, and suggests areas for intervention and study to help improve FT and outcomes for radiation oncology patients.
