Abstract:
e18522 Background: Bone marrow transplant (BMT) has become an increasingly common treatment modality for both malignant and non-malignant conditions. However, BMT requires significant healthcare and financial resources, which can result in allocation disparities across socioeconomic, demographic, and racial/ethnic groups. The data exploring how demographic disparities impact survival after BMT is limited, particularly within the adolescent and young adult (AYA) population, defined as patients between the ages of 15 and 39 years. The goal of this study was to assess overall survival of AYA patients undergoing transplant at our institution and to gain insight into if demographic factors impact the likelihood of mortality after transplantation. Methods: Patients aged 15-39 who underwent transplant at the Wilmot Cancer Institute in Rochester, NY between 2012-2020 were identified. Information regarding demographic characteristics, indication for transplant, and mortality was collected. The primary endpoint was overall survival (OS), defined as the time from transplant to the date of death from any cause or the date of last in-person contact. Survival criteria were estimated using the Kaplan-Meier method and compared using mortality odds ratios. These analyses were stratified by indication for transplant, recorded race/ethnicity, gender, and by age. Results: 169 patients met inclusion criteria, and median OS for the entire cohort was not reached. Of 108 allogenic transplant recipients, median OS was 7.85 years (95% CI [3.3, not estimated]). Median OS for patients receiving transplant for solid tumor pathology was 3 years (95% CI [0.4 years, not estimated] ), compared to other indications for transplant where survival exceeded the median. For allogenic transplant patients, median OS for Black patients was 4.8 years (95% CI [0.7 years, not estimated]), 7.8 years for Caucasian patients (95% CI [3.3 years, not estimated] ), median OS was not reached for Hispanic patients, and 1.1 years for all other minorities (95% CI [0.4 years, not estimated]) (p = 0.28). There was no significant difference in mortality based on insurance type or gender for either type of transplant. There was a significant difference in mortality for allogenic transplant patients based on average median household income when compared at an average income of $60,000/ year (OR 2.6, 95% CI [1.164, 5.6] p = 0.0097). Conclusions: Overall survival for AYA patients who had a transplant for any indication at our institution was better than expected. There were no significant differences for either transplant type based on gender, racial/ethnic background, gender, age, or indication for transplant. There was a significant difference based on median household income. Larger multi-institutional studies are likely needed to accurately identify further demographic disparities.
