Abstract

Introduction: The use of multiagent chemotherapy in acute lymphoblastic leukemia (ALL) has resulted in improvement in overall survival (OS), albeit to a different extent across various age groups. This large database study aims to assess the disparity in the utilization of chemotherapy in ALL in the real-world setting. Materials and Methods: Using the Surveillance, Epidemiology, and End Results database, patients with ALL diagnosis from 2006 to 2016 were identified. Baseline characteristics were compared between the groups who did vs. did not receive chemotherapy using χ2 test. Multivariable logistic regression was used to evaluate the association between various sociodemographic factors and the receipt of chemotherapy in the entire cohort and in different age groups. Results: Out of 16,196 patients, 1258 patients (8%) did not receive chemotherapy. There was a steady increase in the number of patients who did not receive chemotherapy with advancing age: 2.5% (0-18 years), 5.2% (19-40 years), 9.3% (41-65 years), and 36.2% (>65 years). There was an upward trend in the receipt of chemotherapy in patients >65 years over the last decade. In multivariate analysis, the likelihood of receiving chemotherapy decreased with advancing age, single or widowed status, low income and educational status, and lack of insurance. Insurance status was an independent predictor of receipt of chemotherapy across each age category. Conclusion: A significant proportion of patients >65 years do not receive chemotherapy in the United States. Age, marital status, income, education, and insurance status contribute to the disparity in utilization of chemotherapy.
