83 Background: Colon cancer is among the leading causes of cancer-related morbidity and mortality globally, with an increasing incidence observed in younger populations. Lifestyle and metabolic risk factors seem to play an important role in this rising incidence. Glucagon-like peptide-1 (GLP-1) receptor agonists are widely used for the treatment of type 2 diabetes and obesity. Emerging evidence suggests that these agents may have potential anti-tumor activity as GLP-1 signaling may influence pathways involved in cell proliferation and inflammation. Our study aims to evaluate the impact of GLP-1 receptor agonists on outcomes among patients with colon cancer with comorbid obesity, exploring potential interactions between metabolic modulation and disease behavior. Methods: A retrospective cohort study was conducted using the US Collaborative Network TriNetX, covering January 2000 to December 2023, encompassing data from 105 global healthcare organizations. Adult patients aged 18 and above with colon cancer and comorbid obesity were identified and then stratified into two groups based on treatment with GLP-1 agonists or not. The two groups were then propensity-matched based on age, sex, race, and common comorbidities. We followed these patients for 5 years to assess outcomes, including overall mortality, myocardial infarction, sepsis, acute pancreatitis, need for mechanical ventilation and hemodialysis. Results: We identified 1986 patients with colon cancer and obesity who received GLP-1 receptor agonists, and 16384 patients with colon cancer and obesity who did not receive GLP-1 therapy. The average age was 68.8 years in the first cohort and 74.3 years in the second cohort. After propensity matching, each cohort consisted of 1983 patients with similar baseline characteristics and ethnicity distribution. Our analysis found that over 5 years, patients with colon cancer and obesity who received GLP-1 receptor agonists had a significantly lower risk of overall mortality (Hazard Ratio (HR): 0.461, 95% CI: 0.401 to 0.532, p-value < 0.001), myocardial infarction (HR: 0.827, 95% CI: 0.668 to 0.993, p-value =0.005), sepsis (Risk Difference: -3.48%, 95% CI: -4.774 to -2.185, p-value < 0.001), and need for mechanical ventilation (HR: 0.486, 95% CI: 0.321 to 0.739, p-value = 0.037). There was no statistically significant difference in the risk of acute pancreatitis and need for hemodialysis between the two subgroups. Conclusions: Our study revealed that patients with colon cancer and obesity who received GLP-1 receptor agonists had a significantly lower risk of mortality, myocardial infarction, sepsis, and need for mechanical ventilation. Further longitudinal cohort studies are imperative to better understand these associations and guide evidence-based clinical practice in this population.

517 Background: Hepatocellular carcinoma (HCC) is a major cause of cancer related morbidity and mortality worldwide, with increased incidence in patients with chronic liver disease, obesity and metabolic syndrome. Of note, increasing burden of metabolic dysfunction-associated steatohepatitis (MASH) and non-alcoholic fatty livery disease (NAFLD) has contributed to increased incidence of cirrhosis and progression to HCC. Glucagon-like peptide-1 (GLP-1) receptor agonists are widely used for the treatment of type 2 diabetes and obesity. Their pleotropic benefits including improved insulin sensitivity, potential anti-proliferative and anti-inflammatory benefits may significantly benefit these patients by potentially reduced hepatic inflammation and steatosis. Our study aims to evaluate the impact of GLP-1 receptor agonists on outcomes among patients with hepatocellular carcinoma with comorbid obesity, exploring potential interactions between metabolic modulation and disease behaviour. Methods: A retrospective cohort study was conducted using the US Collaborative Network TriNetX, covering January 2000 to December 2023, encompassing data from 105 global healthcare organizations. Adult patients aged 18 and above with HCC and comorbid obesity were identified and then stratified into two groups based on treatment with GLP-1 agonists or not. The two groups were then propensity-matched based on age, sex, race, and common comorbidities. We followed these patients for 5 years to assess outcomes, including overall mortality, myocardial infarction, acute pancreatitis, sepsis, need for mechanical ventilation and hemodialysis. Results: We identified 401 patients with HCC and obesity who received GLP-1 receptor agonists, and 3974 patients with HCC and obesity who did not receive GLP-1 therapy. The average age was 63.7 years in the first cohort and 61.4 years in the second cohort. After propensity matching, each cohort consisted of 399 patients with similar baseline characteristics and ethnicity distribution. Our analysis found that over 5 years, patients with HCC and obesity who received GLP-1 receptor agonists had a significantly lower risk of overall mortality (Hazard Ratio (HR): 0.48, 95% CI: 0.371 to 0.623, p-value = 0.001). There was no statistically significant difference in the risk for myocardial infarction, acute pancreatitis, sepsis, need for mechanical ventilation and hemodialysis between the two subgroups. Conclusions: Our study revealed that patients with HCC and obesity who received GLP-1 receptor agonists had a significantly lower risk of mortality. Further longitudinal cohort studies are imperative to better understand these associations and guide evidence-based clinical practice in this population.

402 Background: Trastuzumab deruxtecan (T-DXd) is a HER2-targeted antibody-drug conjugate (ADC) with a cytotoxic payload. TDXd was approved in 2021 to be used in advanced gastric or GEJ cancers. Although given the recent approval, real-world evidence on efficacy and safety is limited. We sought to evaluate the efficacy and safety of T-DXd through a combined meta-analysis of clinical trials and real-world studies. Methods: A comprehensive search was conducted across PubMed, Embase, Scopus, and Clinicaltrials.gov databases. The original studies evaluating T-DXd in patients with metastatic/recurrent gastric/gastroesophageal junction (GEJ) cancers were included in the analysis. The pooled objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and the incidence of adverse events (AEs) were analyzed. A random-effects model was used for meta-analysis, and the heterogeneity of the data was evaluated by Chi-sq Q test and the I 2 statistic using OpenMeta [Analyst] (Tufts Medical Center, Boston, MA, USA). Results: This meta-analysis incorporated 8 studies (3 phase II clinical trials, 5 retrospective studies) comprising 915 patients with advanced HER2-positive gastric/GEJ cancer. The median patient age was 66.5 years (range: 27–89), with 75.4% males, 70.4% Asian, and 29.0% Caucasians. 77.9% had an ECOG performance status of 0–1, while 21.8% had ECOG ≥2. Histologically, 53.6% had intestinal and 22.9% diffuse-type adenocarcinoma. HER2 overexpression (IHC3+) was observed in 75.8% of evaluable cases, and 22.4% were IHC2+/FISH positive. 77.6% had primary gastric and 22.4% GEJ tumors. The median line of therapy was 3 (range: 2–11), with prior immune checkpoint inhibitor use in 31.8% and prior surgery in 44.5% .The pooled ORR was 47.7% (95% CI 43.0-52.4%) and DCR was 82.50% (79.40%–85.72%); PFS and OS were 4.92 and 9.86 months, respectively. Safety analysis revealed grade ≥3 AEs in 48.2% of patients, neutropenia (24.5%) being the most common. Treatment discontinuation due to adverse events occurred in 12.2%, and dose reductions were required in 21.5%. Patient-reported outcomes were not assessed in any of the studies. Conclusions: Our meta-analysis, encompassing both clinical trials and real-world data, confirms the encouraging efficacy of T-DXd in gastric/GEJ cancers, with a pooled ORR of 47.7% and a median PFS of 4.92 months, and supports its use as an early-line treatment in this challenging disease landscape. This analysis also highlights the significant incidence of grade ≥3 AEs, particularly neutropenia, which necessitates vigilant monitoring and proactive management. Future research should focus on optimizing patient selection, exploring combination therapies, and refining dosing strategies to maximize clinical benefit while mitigating toxicity.

Abstract Background: Eltrombopag and romiplostim are thrombopoietin receptor agonists approved for treating thrombocytopenia in various conditions. Post-marketing surveillance data provide valuable insights into their real-world safety profiles. Objective: To analyze adverse event reports for eltrombopag and romiplostim from the FDA Adverse Event Reporting System (FAERS) database to characterize their safety profiles and identify potential safety signals. Methods: We analyzed FAERS reports for eltrombopag and romiplostim from 2015 to 2024. Reports were classified by System Organ Class (SOC), seriousness criteria, patient demographics, time to onset, and clinical outcomes. Descriptive statistics were used to characterize adverse event patterns. Results: A total of 3500 adverse event reports were identified (eltrombopag: n=2262; romiplostim: n=1238). Mean patient age was 57.5 years for eltrombopag and 58.5 years for romiplostim, with female predominance (57.6% and 56.4%, respectively). For eltrombopag, the most frequently reported adverse events were hepatic disorders, with 29.8% of reports involving hepatobiliary events. The top adverse events included ALT increased (n=124), bilirubin increased (n=120), jaundice (n=117), AST increased (n=109), and hepatic failure (n=107). Thrombotic events occurred in 20.5% of eltrombopag reports. The serious adverse event rate was 51.3%, with a mortality rate of 3.3%. For romiplostim, injection site reactions were the most common adverse events, occurring in 18.3% of reports. The most frequently reported events were injection site reaction (n=80), injection site erythema (n=76), and injection site pain (n=71). Thrombotic events occurred in 23.3% of romiplostim reports. The serious adverse event rate was 48.6%, with a mortality rate of 2.7%. The median time to onset was similar for both drugs (eltrombopag: 74 days; romiplostim: 73 days), with most events occurring within 90 days of treatment initiation. Geographic distribution showed predominant reporting from the United States, followed by Japan and European countries. Conclusions: This FAERS analysis confirms known safety profiles of both thrombopoietin receptor agonists. Eltrombopag demonstrates a clear hepatic safety signal requiring regular liver function monitoring, while romiplostim shows expected injection site reactions. Both drugs exhibit similar rates of thrombotic complications. These findings support current prescribing guidelines emphasizing the need for appropriate patient monitoring and risk-benefit assessment in clinical practice.

Abstract Introduction Hodgkin's lymphoma is known to have favorable survival outcomes; however, limited data exist regarding survival disparities between rural and urban populations. In this study, we aimed to investigate the differences in survival outcomes between the two populations. Methods Data for patients diagnosed with Hodgkin lymphoma (HL) between 2000 and 2015 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Rurality was identified using the Rural-Urban Continuum Codes (RUCC). Patients aged ≥ 20 years with HL as the only primary malignancy were included. Individuals with unknown race or those diagnosed at autopsy were excluded. The Ann Arbor Staging system was utilized for HL staging at diagnosis. HL-specific survival was defined as the time from diagnosis to death attributable to HL and was censored at the time of death from other causes or at last follow-up. Meanwhile, overall survival (OS) was defined as the time from diagnosis to death from any cause and was censored if the patient was still alive. A Cox proportional hazards model was performed to analyze the predictors for 10-year overall and HL-specific mortality. All statistical analyses were conducted using RStudio (version 2024.12.0). Results Between 2000 and 2015, a total of 22,505 patients diagnosed with Hodgkin lymphoma (HL) were included in the analysis. Among them, 13,657 (61%) were aged between 20 and 44 years. Overall, 10,137 patients (47%) were female, 14,885 (66%) were White, 2,672 (12%) were Black, and 3,724 (17%) were Hispanic. The majority of patients resided in urban counties, while only 2,266 (10.1%) lived in rural areas. Among rural patients, 845 (37%) were diagnosed with stage II disease, followed by 475 (21%) with stage III at the time of diagnosis. Notably, both the 10-year overall survival (69.5%) and Hodgkin lymphoma–specific survival (79.7%) were significantly lower among rural patients compared with urban patients (75.3% and 83.5%, respectively; p &lt; 0.001). In the multivariable model for 10-year HL-specific survival, older age (&gt; 65 years) was associated with the highest risk of mortality (HR 10.32; 95% CI 9.42–11.32). Although survival improved over the study period, male patients remained at increased risk of mortality (HR 1.26; 95% CI 1.18–1.35). Urban residence, diagnosis in more recent years, early stage, female sex, White race, and married status were independently associated with improved overall survival (p &lt; 0.01). Conclusion In this population-based study, both the 10-year overall and HL-specific survival were consistently lower among rural vs. urban patients. Male sex, older age, and unmarried status were particularly associated with worse survival outcomes. Further research is warranted to identify possible strategies for improving healthcare access and reducing survival disparities among rural patients.

Abstract Introduction: CAR T-cell therapy represents a pivotal treatment for individuals with relapsed or refractory (R/R) MM. Currently, two CAR T-cell therapeutics have received regulatory approval: Abecma (idecabtagene vicleucel, ide-cel) and Carvykti (ciltacabtagene autoleucel, cilta-cel). Although direct comparative investigations delineating the efficacy of these modalities are absent, clinical trials have shown significant disparities in response and remission rates between these therapies. Both agents are implicated in the manifestation of CRS and ICANS; however, variations in the frequency and severity of these adverse effects have been observed. We harnessed data from the National Inpatient Sample (NIS) to gain a deeper understanding of the incidence of different adverse events associated with both CAR T products in MM. Method: In this retrospective study, the 2022 NIS database was used to identify hospitalizations with MM and those who received ide-cel or cilta-cel using appropriate ICD-10-CM diagnostic and ICD-10-PCS procedure codes. Data on CRS, ICANS, infections, and adverse cardiac events were extracted using relevant ICD-10-CM codes. These outcomes were compared between the two CAR-T products using Pearson's chi-square analysis. Multivariate logistic regression was also performed, adjusting for demographics, hospital-specific characteristics, and comorbidities. Results: We identified 805 patients with MM who received CAR T-cell therapy, among whom 530 patients (60.4% male; 67% Caucasian, 14.6% African American and 17.5% other ethnicities) received ide-cel and 275 patients (70.9% male; 79.6% Caucasian, 14.3% African American and 6.1% other ethnicities) received cilta-cel. The incidence of CRS was 72.6% for ide-cel and 56.4% for cilta-cel, and the difference was almost statistically significant by chi-square analysis (p = 0.051). This difference was not statistically significant after multivariate analysis [Adjusted Odds ratio (OR) = 0.5, CI 0.2 to 1.3, p=0.154]. The incidence of ICANS was 19.8% for ide-cel and 18.2% for cilta-cel, and it was not statistically significant by chi-square analysis (p = 0.825). Among cardiovascular events, there was no significant difference in the incidence of cardiogenic shock (ide-cel vs cilta-cel, 0.9% vs 0%, p = 0.497), stroke (0.9% vs 1.8%, p = 0.661) and arrhythmias (22.6% vs 21.8%, p = 0.892) between these CAR T-cell therapies. Furthermore, there were no significant differences in the incidence of infectious complications, including pneumonia (1.9% vs 0%, p = 0.334), sepsis (0.9% vs 3.6%, p = 0.247), or septic shock (0.9% vs 0%, p = 0.430) between these CAR T-cell therapies. There was no significant difference in all-cause in-hospital mortality between these therapies (1.9% vs 5.5%, p = 0.181). Conclusion: There was no significant difference in the occurrence of CRS and ICANS between ide-cel and cilta-cel in our study. Both CAR T-cell therapies have the potential to cause infections and cardiovascular issues, necessitating careful monitoring, early detection, and timely treatment. When choosing between these CAR T-cell therapies, several factors should be considered, including the patient's previous treatment history, manufacturing time, cost, availability, and potential short-term and long-term side effects. Our study has some limitations, including its retrospective design, dependence on ICD-10 codes for identifying patients with adverse events, and the lack of long-term longitudinal data on adverse effects. However, this study provides important insights for hematologists regarding the rates of specific adverse events associated with both the CAR T-cell products in a real-world setting.

Abstract Background: Luspatercept, an erythroid maturation agent, has shown efficacy in improving anemia in both β-thalassemia and lower-risk myelodysplastic syndromes (MDS). In the BELIEVE trial, which led to its approval in transfusion-dependent β-thalassemia, thromboembolic events were notably higher in patients with risk factors such as splenectomy. More recently, the COMMANDS trial demonstrated superior transfusion independence with luspatercept over erythropoiesis-stimulating agents (ESAs) in ESA-naive, lower-risk MDS patients. However, limited data exist regarding comparative thrombotic risk in real-world MDS populations. We conducted a multicenter, real-world study to evaluate thrombotic event rates associated with luspatercept versus ESAs in MDS patients without prior venous thromboembolism (VTE). Methods: We queried the TriNetX Research Network, a federated real-time electronic health record (EHR) database covering over 100 million patients across major healthcare organizations. Adults (≥18 years) with a diagnosis of MDS (ICD-10-CM code D46) and no prior history of deep vein thrombosis (DVT) or pulmonary embolism (PE) were included. Patients were stratified based on treatment with luspatercept or ESAs (epoetin alfa or darbepoetin alfa). Propensity score matching (PSM) using a 1:1 nearest-neighbor algorithm without replacement was performed to balance demographics and clinical covariates. Primary outcomes included the incidence of DVT, PE, and composite VTE events within 12 months of therapy initiation. Results: A total of 6,448 patients with MDS and no prior VTE were identified: 5,698 received ESAs and 750 received luspatercept. The overall mean age was 72.5 ± 13.5 years, with 48.1% male. After PSM, 741 patients were included in each treatment arm. The matched cohort had a mean age of 76.7 ± 10.7 years, and 41.3% were female. In the ESA group, 58/741 (7.8%) developed DVT compared to 27/741 (3.6%) in the luspatercept group (Hazard Ratio [HR] 1.4; 95% CI, 0.9–2.3). PE occurred in 27 ESA-treated patients (3.6%) versus 13 luspatercept-treated patients (1.8%) (HR 1.3; 95% CI, 0.6–2.7; p=0.941). The overall composite VTE rate was 10.0% (74/741) in the ESA group and 4.9% (36/741) in the luspatercept group (HR 1.3; 95% CI, 0.9–2.0; p=0.732). Conclusion: In this large, multicenter real-world analysis, we observed a numerically lower incidence of thrombotic events with luspatercept compared to erythropoietin-based agents in patients with MDS, though differences did not reach statistical significance. These findings support the thrombotic safety profile of luspatercept observed in clinical trials and warrant further prospective validation.

Abstract Introduction Acute chest syndrome (ACS) is a life-threatening complication of sickle cell disease that often requires hospitalization and urgent intervention. Hospitalized patients may present with multiple acute conditions necessitating glucocorticoid therapy. Although glucocorticoids are well known for their anti-inflammatory effects, their use in ACS remains controversial due to concerns about worsening of underlying infection, progression to sepsis, and subsequent respiratory failure. This study aims to evaluate the impact of concomitant glucocorticoid use on clinical outcomes in patients with ACS. Methods A retrospective cohort study was conducted using the US Collaborative Network TriNetX, covering January 2000 to December 2023, encompassing data from 105 global healthcare organizations. Adult patients aged 18 and above with acute chest syndrome were identified and then stratified into two groups based on treatment with glucocorticoids during the index hospitalization or not. The two groups were then propensity-matched based on age, sex, race, and comorbidities. We followed these patients for 5 years to assess outcomes, including overall mortality, simple transfusions, exchange transfusions, need for mechanical ventilation, incidence of pneumonia, influenza, sepsis without shock, sepsis with shock, and need for hemodialysis. Results We identified 4197 patients in the acute chest syndrome with glucocorticoids cohort and 8211 patients in the acute chest syndrome without glucocorticoids cohort. After propensity matching, each cohort consisted of 4111 patients with similar baseline characteristics. Our analysis found that over 5 years, patients with acute chest syndrome who received glucocorticoids during the index hospitalization had a significantly higher risk of overall mortality (Hazard Ratio (HR): 1.361, 95% CI: 1.158 to 1.599, p-value &lt;0.001), simple transfusions (HR: 2.191, 95% CI: 2.015 to 2.381, p-value =0.009), exchange transfusions (Risk difference: 0.008, 95% CI: 0.003 to 0.013, p-value =0.001), need for mechanical ventilation (Risk difference: 0.024, 95% CI: 0.016 to 0.032, p-value &lt;0.001), pneumonia (HR: 1.190, 95% CI: 1.111 to 1.276, p-value =0.004), influenza (Risk difference: 0.044, 95% CI: 0.029 to 0.059, p-value &lt;0.001), sepsis without shock (Risk difference: 0.016, 95% CI: 0.007 to 0.024, p-value &lt;0.001), and sepsis with shock (Risk difference: 0.026, 95% CI: 0.018 to 0.034, p-value &lt;0.001). There was no statistically significant difference in the need for hemodialysis between the two subgroups. Conclusion Our study found that patients with acute chest syndrome who were exposed to glucocorticoids during the index hospitalization had a significantly increased risk of overall mortality, simple transfusions, exchange transfusions, need for mechanical ventilation, incidence of pneumonia, influenza, sepsis without shock, and sepsis with shock. Further longitudinal cohort studies are imperative to better understand these associations and guide evidence-based clinical practice in this population.

Abstract Background: Renal allograft thrombosis, though commonly attributed to surgical or anatomical causes, is increasingly linked to inherited thrombophilia, including Factor V Leiden, prothrombin gene mutations, and deficiencies in protein C, protein S, or antithrombin III. These conditions raise the risk of early graft thrombosis and may impair graft survival. While therapeutic anticoagulation has been proposed as a preventive strategy, there are no established guidelines to direct its use in transplant recipients with thrombophilia. Methods: We systematically searched PubMed, Embase, and the Cochrane Library from inception to July 2025 to assess the role of therapeutic anticoagulation in kidney transplant recipients with thrombophilia. Two reviewers independently screened 275 titles and abstracts, as well as 35 full-text articles, using Covidence. Eligible studies included observational cohorts and case series (with≥2 patients) that reported anticoagulation outcomes in adult transplant recipients with thrombophilia. Case reports (n=1), reviews, pediatric studies were excluded. No randomized controlled trials were identified. Eleven observational studies met our inclusion criteria. Results: Type of anticoagulation medication, timing of use, and outcome reporting were heterogeneous. Only one retrospective cohort study directly compared anticoagulated and non-anticoagulated patients, reporting no thrombotic events in the anticoagulated group versus two in the control group. Several studies suggested benefits of anticoagulation, particularly in patients with antiphospholipid syndrome or lupus anticoagulant. Bleeding complications were reported in some of the studies, with major bleeding rates ranging from 20% to 30% in some cohorts. One study noted a 30% rate of perinephric hematomas in patients receiving perioperative heparin. Due to significant heterogeneity in study design, anticoagulation protocols, thrombophilia, and outcomes reported, meta-analysis was not feasible. Conclusion: Therapeutic anticoagulation may reduce thrombotic risk in kidney transplant recipients with thrombophilia, but bleeding complications and limited comparative evidence preclude general recommendations. Randomized and controlled studies are needed to better define indications and safety. Until then, anticoagulation decisions should be individualized based on patient risk factors and clinical context.

Abstract Introduction: CAR T-cell therapy is an important treatment option for patients with relapsed or refractory (R/R) DLBCL. Three CAR T-cell products have received approval: axicabtagene ciloleucel (Yescarta), lisocabtagene maraleucel (Breyanzi), and tisagenlecleucel (Kymriah). Although direct head-to-head studies comparing the three therapies do not exist, clinical trials have revealed notable differences in response rates and remission rates among them. All three products induce CRS and ICANS; however, variations in the incidence and severity of these adverse effects have been observed. We utilized data from the National Inpatient Sample (NIS) to gain further insights into the incidence of various adverse events associated with different CAR-T products in DLBCL. Method: In this retrospective study, the 2022 NIS database was used to identify hospitalizations with DLBCL and those who received Yescarta, Breyanzi, or Kymriah using appropriate ICD-10-CM diagnostic and ICD-10-PCS procedure codes. Data on CRS, ICANS, infections, and adverse cardiac events were extracted using relevant ICD-10-CM codes. These outcomes were compared across different CAR-T products using Pearson's chi-square analysis. Multivariate logistic regression was also performed, adjusting for demographics, hospital-specific characteristics, and comorbidities. Results: We identified 1440 patients with DLBCL. Among these, 1100 patients (64.6% male; 70.7% Caucasian, 8.8% African American, 20.5% other ethnicities) received Yescarta, 90 patients (66.7% male; 82.4% Caucasian, 0% African American, 17.7% other ethnicities) received Kymriah and 250 patients (64% male; 82.6% Caucasian, 10.9% African American, 6.5% other ethnicities) received Breyanzi. The incidence of CRS was 52% for Breyanzi, 44.4% for Kymriah and 68.6% for Yescarta, and the difference was statistically significant by chi-square analysis (p = 0.03). This difference remained statistically significant for Kymriah after multivariate analysis [Adjusted Odds ratio (OR) = 0.3, CI 0.1 to 0.9, p=0.032], but not for Breyanzi (Adjusted OR = 0.3, CI 0.1 to 0.9, p=0.032) in comparison to Yescarta. The incidence of ICANS was 16% for Breyanzi, 22.2% for Kymriah, and 33.2% for Yescarta, with a statistically significant difference observed by chi-square analysis (p = 0.05). This difference remained statistically significant for Breyanzi after multivariate analysis [Adjusted OR = 0.3, CI 0.1 to 0.6, p=0.002], but not for Kymriah (Adjusted OR = 0.6, CI 0.1 to 2.9, p=0.551) in comparison to Yescarta. Among cardiovascular events, there was no significant difference in the incidence of acute myocardial infarction (Yescarta vs Kymriah vs Breyanzi, 0.5% vs 0% vs 0.2%, p = 0.487), stroke (0.5% vs 5.6% vs 2%, p = 0.07), cardiogenic shock (0.5% vs 0% vs 0%, p = 0.880), and arrhythmias (20.9% vs 27.8% vs 32%, p = 0.258) among these CAR T-cell therapies. Furthermore, there were no significant differences in the incidence of infectious complications, including pneumonia (5.9% vs 5.6% vs 2%, p = 0.510), sepsis (5% vs 5.6% vs 6%, p = 0.962), or septic shock (2.3% vs 0% vs 0%, p = 0.535) among these CAR T-cell therapies. There was no difference in all-cause in-hospital mortality across these therapies (2.3% vs 5.6% vs 2%, p = 0.692). Conclusion: Kymriah showed lower CRS rates and Breyanzi showed lower ICANS rates in comparison to Yescarta in our study. All CAR T-cell therapies have the potential to cause infections and cardiac events, which require monitoring, early identification and prompt treatment. When selecting among various CAR T-cell products, several factors must be considered, including the patient's lymphoma type, prior treatment history, manufacturing turnaround time, cost, availability, and potential short-term and long-term side effects. The limitations of our study include its retrospective nature, reliance on ICD-10 codes to identify patients with adverse events, and the absence of longitudinal data on long-term adverse events. Nevertheless, this study provides essential insights for hematologists regarding the incidence of specific adverse events associated with different CAR T-cell products within the real-world population.
