Abstract

Introduction: Patients with adolescent idiopathic scoliosis (AIS) are susceptible to high doses of radiation from radiographs. The purpose of this study was to examine the future cost of radiation-induced breast cancer in patients with AIS and its potential financial and mortality impact. Methods: A literature review identified articles relating radiation exposure in patients with AIS to increased risk for cancer. Based on population statistics and breast cancer treatment costs in the year 2020, the financial impact of radiation-induced breast cancer and the estimated number of additional deaths per year due to breast cancer for patients with AIS were calculated. Results: The US female population in 1970 was 205.1 million. Based on a prevalence of 3.0%, an estimated 3.1 million patients had AIS in 1970. With an incidence of breast cancer in the general population of 128.3/100,000 and a standardized incidence ratio of 1.82—2.4 for breast cancer in patients with scoliosis, there will be a 3,282 to 5,603 patient increase in radiation-induced breast cancer in patients with scoliosis over the general population. With a projected base cost of $34,979 per patient for the first year of breast cancer diagnosis in 2020, the cost of radiation-induced breast cancer will be 114.8 to 196.0 million dollars per year. Using a standardized mortality ratio of 1.68 for scoliosis radiation-induced breast cancer, there will be an expected increase in deaths of 420 patients due to breast cancer presumably secondary to radiation exposure in the evaluation and treatment of AIS. Conclusion: The estimated radiation-induced breast cancer financial impact in 2020 will be between 114.8 and 196.0 million dollars per year, with an increase in deaths of 420 patients per year. Low-dose imaging systems reduce radiation exposure by up to 45 times while maintaining sufficient image quality. New low-dose radiography should be used whenever possible with patients with AIS. Level of Evidence: Level 5.
