TO QUANTIFY AND EVALUATE THE ECONOMIC COST OF BREAST CANCER SURVIVORS THROUGH CROSS-SECTIONAL STUDY Need to break up into subsections – background, objective and methods Breast cancer is the most common cancer in women worldwide. Economic burden of breast cancer is significant and expected to increase substantially in the future due to medical advancement in treating cancer following cancer diagnosis. In the literature, breast cancer survivors tend to face greater economic cost and productivity loss than persons without cancer history. Breast cancer affects many working population women. This suggests that breast cancer survivors are important contributors to our economy. Health-related productivity loss is a critical yet unnoticed component of the economic burden face by these survivors. Indirect costs such as productivity loss and caregiver costs incurred by these breast cancer survivors contribute significantly to the economic cost. However, currently there are insufficient local studies conducted to quantify the indirect costs incurred by breast cancer survivors. Thus, this study aims to quantify and evaluate the economic cost of breast cancer survivors. Through the study, we hope to reduce the economic cost by reducing productivity loss with help from employers and health-care policy makers by allowing them to better understand the needs of the survivors and to develop and prioritise cancer survivorship programs and enable transition back to employment smoother for these breast cancer. The economic cost is estimated by collecting medical expenditure data of patients who have completed primary treatment for at least 6 months from the financial database in National Cancer Centre Singapore. In addition, the economic cost is also estimated through questionnaire, which collects information about direct costs outside National Cancer Centre and productivity loss due to absenteeism, presenteeism and income loss. These lost time and opportunity will be translated into fiscal terms for quantitative analysis. Analysis will be conducted using STATA.
