Patient-Reported Financial Toxicity in a Population-Based Cohort of Oropharynx Cancer Survivors.

Abstract

Patients with oropharyngeal squamous cell carcinoma (OPSCC) are at high risk for financial toxicity (FT), but the nature, extent, and predictors of FT experienced after primary radiation therapy (RT) or surgery are poorly understood. We used a population-based sample of patients from the Texas Cancer Registry with stage I to III OPSCC diagnosed from 2006 to 2016 and treated with primary RT or surgery. Of 1,668 eligible patients, 1,600 were sampled, 400 responded, and 396 confirmed OPSCC. Measures included the MD Anderson Symptom Inventory Head and Neck, Neck Dissection Impairment Index, and a financial toxicity instrument adapted from the Individualized Cancer Care (iCanCare) study. Multivariable logistic regression evaluated associations of exposures with outcomes. Of 396 analyzable respondents, 269 (68%) received primary RT and 127 (32%) surgery. The median time from diagnosis to survey was 7 years. Due to OPSCC, 54% of patients experienced material sacrifice (including 28% who reduced food spending and 6% who lost their housing), 45% worried about financial problems, and 29% experienced long-term FT. Independent factors associated with more long-term FT included female sex (odds ratio [OR], 1.72; 95% confidence interval [CI], 1.23-2.40), Black non-Hispanic race (OR, 2.98; 95% CI, 1.26-7.09), unmarried status (OR, 1.50; 95% CI, 1.11-2.03), feeding tube use (OR, 3.98; 95% CI, 2.29-6.90), and worst versus best quartile on the MD Anderson Symptom Inventory Head and Neck (OR, 1.89; 95% CI, 1.23-2.90) and Neck Dissection Impairment Index (OR, 5.62; 95% CI, 3.79-8.34). Factors associated with less long-term FT included age >57 years (OR, 0.54; 95% CI, 0.41-0.71; P < .001) and household income ≥$80,000 (OR, 0.60; 95% CI, 0.44-0.82; P = .001). Primary RT versus surgery was not associated with long-term FT (OR, 0.92; 95% CI, 0.68-1.24). Oropharynx cancer survivors experience high rates of material sacrifice and long-term FT, and we identified important risk factors. Chronic symptom burden was associated with significantly worse long-term financial status, supporting the hypothesis that toxicity mitigation strategies may reduce long-term FT.
