e16342 Background: Pancreatic cancer poses a major challenge due to its high mortality rates and is known as one of the deadliest cancers. The increasing mortality in addition to the aggressive nature of the tumor may be due to major cardiovascular and cerebrovascular events (MACCE). The key to mitigating the risk of pancreatic cancer as well as MACCE, is primary prevention of common risk factors including tobacco use, obesity, dietary factors, alcohol use, and physical activity. Understanding that many of these factors are directly and indirectly influenced by income status, this study aims to explore the relationship between household income on MACCE in pancreatic cancer patients. Methods: Using ICD-10 codes, patients with pancreatic cancer were identified from National Inpatient Sample 2019 database. We included all-cause in-hospital mortality (ACIHM), acute myocardial infarction (AMI), arrythmia, cerebrovascular accident (CVA), and sudden cardiac death (SCD) as MACCE for the outcomes. Baseline characteristics including demographics, comorbidities; and MACCE outcomes were studied using chi-square for categorical or ANOVA for continuous data (statistical significance determined as p-value < 0.05) and results were stratified based on median household income quartiles. Results: Of the 114,235 patients identified with pancreatic cancer who were admitted to the hospital, 25% (28,570) belonged to the first income quartile ($1-47,999), 23.8% (27,235) belonged to the second income quartile ($48,000-60,999), 26.38% (30,135) belonged to the third income quartile ($61,000-81,999), and 24.76% (28,295) belonged to the fourth income quartile ($82,000+). When compared to the patients in the fourth quartile, the adjusted odds ratio (aOR) was found to be higher for all MACCE outcomes for patients in first quartile. The aOR for ACIHM in the first quartile was found to be 1.24 (95% CI 1.06-1.46, p = 0.006) as compared to patients in the fourth quartile. Additionally, the aOR for AMI, was found to be statistically significant in patients belonging to the first quartile at 1.30 (95% CI 1.01-1.70, p = 0.047). Similarly, the aORs for both arrhythmia and SCD were also higher in the population from the first quartile at 3.67 (95% CI 1.10-12.28, p = 0.03) and 1.45 (95% CI 1.01-2.09, p = 0.049). https://docs.google.com/document/d/1v84LyPoGL406_7SDxO1N-wKxwujSgFpf/edit?usp = sharing&ouid = 110330426831507953030&rtpof = true&sd = true. Conclusions: As compared to patients in fourth income quartile, the aOR was found to be higher for all MACCE outcomes for patients in the first income quartile, indicating a vast variation based on income strata. This hints towards a complex interplay of healthcare disparities including but not limited to difficult access to quality healthcare including subspecialities. Further research may be pertinent to explore the causes of this clear disparity to ensure equitable healthcare for all patient population.

e19076 Background: Non-Hodgkin Lymphoma (NHL) is the seventh most prevalent cancer and has sixth highest malignancy mortality in United States. Owing to the advances in treatment of NHL including targeted therapies, the survival of NHL patients has increased over the past decades. However, inequalities may exist in the access to advanced care, clinical trials, and subspecialist appointments in certain patient populations. We aim to study the racial disparities in major cardiovascular and cerebrovascular events (MACCE) in NHL patients. Methods: Using ICD-10 codes, patients with NHL were identified from National Inpatient Sample 2019 database. We included all-cause in-hospital mortality (ACIHM), acute myocardial infarction (AMI), atrial fibrillation (AF), cerebrovascular accident (CVA), and sudden cardiac death (SCD) as MACCE for the outcomes. Baseline characteristics including demographics, comorbidities; and MACCE outcomes were studied using chi-square for categorical or ANOVA for continuous data (statistical significance determined as p-value <0.05) and results were stratified based on patient’s races. Results: Out of the total sample size of 205220 patients admitted with a diagnosis of NHL, 74.94% (153785) were White, 8.95% (18370) were Black, 9.46% (19415) were Hispanic, 3.48% (7140) were Asian/Pacific Islander, 0.42% (875) were Native American, while 2.75% (5635) belonged to other races. When compared to White patients, ACIHM was significantly higher in Black patients with adjusted odds ratio (aOR) of 1.294 (95% CI 1.099-1.523, p=0.002) and Asian/Pacific Islander patients (aOR 1.279, 95% CI 1.005-1.628, p=0.045). Risk of AMI was lower in Black patients (aOR 0.751, 95% CI 0.587-0.96, p=0.023) as compared to White patients. AF risk was significantly lower in Black, Hispanic, and Other race patients compared to White patients. The odds of developing CVA are higher in Asian/Pacific Islander patients (aOR 1.285, 95% CI 1.002-1.649, p=0.048) and of having SCD are higher in Black patients (aOR 2.052, 95% CI 1.5-2.806, p<0.001) when compared to White patients. Conclusions: In patients with NHL, Black patients had higher ACIHM and SCD while Asian/Pacific Islander patients had higher ACIHM and CVA when compared to White patients. Although the reason of disparity is likely multifactorial, the findings of this study highlight the need for development of healthcare strategies stratified by race which may aid to mitigate the increased risk of MACCE in certain races. Further research involving possible genetic influences and social determinants of health contributing to poorer outcomes in Black and Asian/Pacific Islander patients with NHL becomes imperative.
