Acute skin toxicity-related, out-of-pocket expenses in patients with breast cancer treated with external beam radiotherapy
Menée auprès de patientes américaines atteintes d'un cancer du sein, cette étude analyse les effets secondaires de la radiothérapie externe, en particulier les effets associés à sa toxicité sévère pour la peau, puis estime les coûts liés aux traitements non médicaux des symptômes dermatologiques
Purpose Acute skin toxicity is one of the most common side effects of breast cancer radiotherapy. To date, no one has estimated the nonmedical out-of-pocket expenses associated with this side effect. The primary aim of the present descriptive, exploratory study was to assess the feasibility of a newly developed skin toxicity costs questionnaire. The secondary aims were to: (1) estimate nonmedical out-of-pocket costs, (2) examine the nature of the costs, (3) explore potential background predictors of costs, and (4) explore the relationship between patient-reported dermatologic quality of life and expenditures. Methods A total of 50 patients (mean age = 54.88, Stage 0–III) undergoing external beam radiotherapy completed a demographics/medical history questionnaire as well as a seven-item Skin Toxicity Costs (STC) questionnaire and the Skindex-16 in week 5 of treatment. Results Mean skin toxicity costs were $131.64 (standard error [SE] = $23.68). Most frequently incurred expenditures were new undergarments and products to manage toxicity. Education was a significant unique predictor of spending, with more educated women spending more money. Greater functioning impairment was associated with greater costs. The STC proved to be a practical, brief measure which successfully indicated specific areas of patient expenditures and need. Conclusions Results reveal the nonmedical, out-of-pocket costs associated with acute skin toxicity in the context of breast cancer radiotherapy. To our knowledge, this study is the first to quantify individual costs associated with this treatment side effect, as well as the first to present a scale specifically designed to assess such costs. Relevance In future research, the STC could be used as an outcome variable in skin toxicity prevention and control research, as a behavioral indicator of symptom burden, or as part of a needs assessment.
