Pharmacology & Experimental Therapeutics- Division of Biostatistics, Philadelphia, USA 5 Saint Joseph’s University, Erivan K. Haub School of Business, Philadelphia, USA Purpose or Objective Little is known about the financial burden experienced by patients receiving radiation therapy. Furthermore, there are currently no financial toxicity screening tools validated for use in radiation oncology. Material and Methods Physician surveys were used to gauge provider understanding of treatment costs and their willingness to adopt use of financial toxicity screening tools. Post- treatment patient surveys were used to investigate covariates of treatment induced financial risk. Results Of the 210 radiation oncologists that 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. Analysis of patient surveys using logistic regression found age, money owed, and worries about making the copayment as the most important variables in predicting risk of financial toxicity. Thirty-four (22%) patients experienced financial toxicity related to treatment. Our screening model had a very good predictive performance in these data (c- statistic = 0.85).

Material and Methods The study was conducted between 1 st June, 2014 and 31 st March, 2015 at the Radiation Oncology Department, University College Hospital Ibadan, South West Nigeria. All histologically diagnosed cervical cancer patients that have completed treatment and were on follow up were considered. The patients were interviewed using a set of questionnaires which addresses medical and non-medical costs. All costs were expressed in naira and converted to dollar as of January 2014 rate. The data was analysed using the Statistical Package for the Social Sciences (SPSS) version 21.0. Results Seventy-eight (78) cervical cancer patients participated in the study. The mean age of patients was 58.8 (SD=11.7) years and ranged between 35-82 years. Trading was the predominant occupation (79.5%) while civil servants (11.5%) and teachers (7.7%) constituted the rest of the study population. About 10.3% underwent surgery while most had chemotherapy (98.7%) and radiotherapy (97.4%). The commonest histology was squamous cell carcinoma (95%). Majority of the patients perceived the financial burden as a result of cervical cancer to be significant (79.5%). Also none of the patients had any health insurance that covered their treatment. Their mean annual income was $2,215.1 (SD=$3,847.8) The mean total cost incurred by patients was $2,675.9 (SD=$1,251.3) with mean medical costs accounting for $1,713.0 (SD=$889.7); surgery $1,001.6 (SD=$593.9) had the highest mean cost followed with chemotherapy $603.7 (SD=$434.2), radiotherapy $453.7 (SD=$345.4), investigations $433.0 (SD=$371.7) and consultation fee $164.8 (SD=$166.0). The mean non-medical cost was $962.9 (SD=$686.2); lodging $533.7 (SD=$358.3) had the highest mean cost followed with transportation $279.5 (SD=$198.1), feeding $256.2 (SD=$193.7) and domestic services $186.6 (SD=$204.5). Conclusion Financing cervical cancer treatment is a serious burden on patients and their caregivers in our environment as they pay out of pocket. There is need for a comprehensive health insurance program that will incorporate cancer care and help reduce the burden on our patients.

Conclusion Financial toxicity is an important measure for patients and providers that is experienced in approximately one quarter of patients. A financial toxicity screening tool is feasible and can predict patients at high risk of developing financial toxicity due to treatment. Further studies to improve models to predict financial toxicity and how financial toxicity is related to patient outcomes and quality of life are warranted.
