e19094 Background: WM/LPL is an indolent B-cell Non-Hodgkin Lymphoma with prolonged survival and predisposition to secondary malignancies (SM) influencing clinical outcomes and survivorship care. We evaluated the incidence, demography, treatment utilization, and outcomes of SM in patients with WM/LPL using population-based data. Methods: SEER-22 database was used to identify patients with LPL/WM diagnosed between 2000–2022 and stratified by SM. Overall survival (OS) was analyzed using Kaplan–Meier survival analysis and propensity score matched Cox regression was used to assess mortality risk. Hazard ratios were reported, with p<0.05 deemed significant. Results: 22,170 patients with WM/LPL were identified, with a median age of 71 years (IQR 16); the cohort was predominantly male (59.0%), White (84.0%), had a median household income of $50,000–$75,000 (48.9%), and resided primarily in urban areas (89.5%). Among all WM/LPL patients, 20.8% (n=4,615) developed a SM. Patients who developed SM were older than those without (median age 75 vs 70 years, p<0.0001) with 45.2% alive at predefined follow-up. The most common solid organ SM were gastrointestinal adenocarcinoma (16%), prostate cancer (14%), and lung adenocarcinoma (9%), while the leading hematologic SM were plasma cell myeloma (6%), diffuse large B-cell lymphoma (5%), and myelodysplastic syndrome (2%). 35.3% of the cohort received chemotherapy, while 0.1% received cancer-related surgery or radiation. On multivariable analysis, older age (OR 0.82, 95% CI 0.81–0.83), male sex (OR 0.59, 95% CI 0.44–0.80), urban residence (OR 1.99, 95% CI 1.24–3.18), and higher income (OR 2.16, 95% CI 1.13–4.15) were significantly associated with SM diagnosis. Kaplan–Meier analysis demonstrated inferior survival among patients with SM (54.8% vs 45.2%, p<0.0001), with shorter median OS (9 vs 14 years, log-rank p<0.001). Similarly, Propensity-matched analysis revealed worse OS in patients with SM (HR 1.15, 95% CI 1.09–1.22, p<0.001). Median OS varied substantially by SM site (see Table). Conclusions: Our study demonstrates a substantial burden of SMs among patients with WM/LPL and are associated with substantially inferior survival despite the indolent nature of the disease. The marked heterogeneity in SM types and outcomes highlights the need for risk-adapted surveillance, survivorship-focused care, and equitable strategies to address disparities and improve long-term outcomes in this population.

e19092 Background: Advances in immunochemotherapy and cellular treatment have improved outcomes for diffuse large B-cell lymphoma (DLBCL), but the population-level effect and equity of benefit are unclear. Understanding mortality trends and inequality is critical to developing targeted medicines. Methods: We used ICD-10 codes to assess DLBCL mortality from the CDC WONDER Multiple Causes of Death data (1999-2023). The age-adjusted mortality rates (AAMR) per 100,000 were calculated using the 2000 US standard population. Trends were assessed using Joinpoint regression to calculate annual percent change (APC) and average annual percent change (AAPC). Mortality was broken out by gender, race/ethnicity, age group, US Census area, and urban-rural categorization. Results: From 1999 to 2023, the national AAMR for DLBCL decreased from 3.8 to 2.5 per 100,000 (AAPC -2.1%) (p < 0.001). Non-Hispanic White patients saw the greatest decline (AAPC -2.5%), followed by non-Hispanic Black patients (AAPC -1.2%), resulting in increasing racial inequalities (rate ratio Black:White 1.35 in 2023 vs. 1.18 in 1999). Urban areas had much larger mortality decreases than rural areas (AAPC −2.3% versus −1.1%). Regional disparities were clear, with rates typically higher in the Southeast and Midwest. Inflection points were identified in 2006 and 2012, coinciding with widespread use of rituximab-based therapy and better availability of second-line medications. Conclusions: Although DLBCL mortality has decreased throughout the US over the last two decades, progress has been patchy, with significant racial and regional differences. Clinical Takeaway: Targeted interventions addressing access to therapy and early detection in high-risk populations are needed to close persistent DLBCL outcome gaps.

e19046 Background: While outcomes in pts with R/R FL have improved with current SOC treatments (Tx), there remains a need for safe, efficacious, and convenient Tx options. GOLCA is a potential, first-in-class, oral CELMoD designed for Tx of lymphoma, with preferential distribution to lymphoid organs and enhanced activity in lymphoma cell lines. GOLCA induces rapid and deep degradation of Ikaros and Aiolos, leading to direct cell killing and immunomodulatory activity. GOLCA + R was well tolerated and effective in heavily pretreated pts in the two-part Ph 1/2 study, CC-99282-NHL-001. Here, we provide longer f/u in pts with R/R FL from Part B of the study. Methods: Pts with R/R FL with ≥2 prior lines of Tx (≥1 if prior anti-CD20 Tx) received GOLCA orally, once daily at 0.2 mg (n=22) or 0.4 mg (n=38) ± R for up to 2 y or until progressive disease (PD)/unacceptable toxicity. Primary endpoints included safety and RP2D determination; secondary endpoints are preliminary efficacy and PK. Results: As of September 15, 2025, 60 pts were enrolled. In 0.2 and 0.4 mg groups, median prior Tx lines were 3 and 3, 32% and 32% had prior lenalidomide (LEN), 27% and 29% had prior T-cell–redirecting Tx (CAR T and/or bispecific antibody) and 32% and 32% were refractory to last regimen. Tx is ongoing in 6 (27%) and 17 (45%) pts at 0.2 and 0.4 mg, respectively; discontinuations (d/c) were mostly due to PD. Neutropenia, an on-target side effect of GOLCA, was the most common grade 3/4 Tx-emergent adverse event (TEAE) occurring in 59% and 68% of pts at 0.2 and 0.4 mg, followed by anemia (9% and 16%) and febrile neutropenia (9% and 8%). Median time to resolution of neutropenia was 8 days. Dose reductions occurred in 14% and 37% of pts at 0.2 and 0.4 mg, most commonly due to neutropenia (5% and 21%) and febrile neutropenia (5% and 5%). No d/c or deaths were from GOLCA-related TEAEs. Non-hematologic TEAEs were infrequent and mostly low grade. In efficacy-evaluable pts (GOLCA 0.2 and 0.4 mg + R, n=22 and n=36), median f/u was 14.03 months (mo), overall response rate (ORR) was 77% (complete response rate [CRR], 41%) at 0.2 mg, and 97% (CRR, 78%) at 0.4 mg. In the 0.4 mg group, responses were consistent in high-risk subsets including pts with prior LEN (ORR, 100%; CRR, 75%) and/or T-cell–redirecting Tx (ORR, 91%; CRR, 64%). GOLCA 0.4 mg + R demonstrated durable responses (median DOR, 9.17 mo; 91% of pts who achieved a CR remained in CR at cutoff). Conclusions: With longer f/u, GOLCA + R demonstrated promising efficacy with durable responses and no new safety signals. The 0.4 mg group had higher ORR and CRR than 0.2 mg, including in pts with prior LEN-based and/or T-cell–redirecting Tx, with a manageable safety profile at both doses. The results support the development of GOLCA + R as a fixed-duration, chemotherapy-free outpatient Tx in the Ph 3 GOLSEEK-4 study in 2L+ FL (NCT06911502). Clinical trial information: NCT03930953 .

e16469 Background: Pancreatic cancer remains among the most lethal malignancies worldwide, with limited improvement in survival despite therapeutic advances. Contemporary real-world data characterizing recent diagnosis acceleration, demographic disparities, and future burden remain limited. We evaluated national trends in pancreatic cancer burden using a large federated electronic health record (EHR) network. Methods: We conducted a retrospective multicenter real-world cohort analysis using the TriNetX Research Network. Adult patients (≥18 years) with pancreatic cancer were identified using ICD-10-CM code C25. Annual newly recorded diagnosis proportions, prevalence, and incidence rates were calculated for calendar years 2020–2024 and stratified by age, sex, race, and ethnicity. New diagnoses were defined as first recorded pancreatic cancer encounters within each calendar year. Exploratory future burden projections were generated through 2028 using autoregressive integrated moving average (ARIMA) time-series modeling. Results: Between 2020 and 2024, newly recorded pancreatic cancer diagnoses increased from 0.032% (21,118 cases) to 0.046% (23,660 cases), representing a descriptive relative increase exceeding 40%. Prevalence increased from 0.101% (65,971 cases) to 0.145% (74,139 cases), reflecting rapid expansion of disease burden. Diagnosis burden increased markedly with advancing age, with the highest burden observed among individuals aged ≥65 years. Males consistently demonstrated higher diagnosis proportions compared with females. Racial stratification demonstrated higher recorded diagnosis proportions among White and Asian populations, while substantial prevalence burden persisted across all racial groups, potentially reflecting differences in healthcare utilization and access. Non-Hispanic individuals exhibited higher diagnosis and prevalence proportions compared with Hispanic individuals. Exploratory ARIMA forecasting projected continued growth in pancreatic cancer burden through 2028, with widening uncertainty intervals over time, indicating escalating long-term healthcare demand. Conclusions: Pancreatic cancer burden in the United States is rapidly increasing, with disproportionate impact among older adults and males and persistent demographic disparities. Exploratory projection modeling suggests continued expansion of disease burden in the near term. These findings highlight the urgent need for earlier detection initiatives, risk-adapted screening strategies, and healthcare system preparedness to address the growing national impact of pancreatic cancer.

e16377 Background: 1L systemic treatment of mPDAC can lead to severe adverse events (AEs). To contextualize the safety profile of irinotecan-based regimens, real-world data were used to characterize AEs and their management in patients receiving 1L mPDAC treatment with FOLFIRINOX (FFX) or gemcitabine+Nab-paclitaxel (Gem+NabP). Methods: De-identified data from Mayo Clinic electronic health records (all sites; records collected 2010–2023) were used. Natural language processing was leveraged to confirm staging and metastatic classification and to extract treatment data. Adults with mPDAC with stage IV and/or TNM staging of M1 who received ≥ 1 dose of FFX or Gem+NabP were included. Primary endpoint: proportion of patients with AEs of interest (diarrhea, nausea, vomiting, neuropathy, and neutropenia) following initiation of 1L treatment. Secondary endpoints: proportion of patients who received treatment for each AE of interest, median time to resolution and treatment of each AE of interest, and proportion of patients who switched mPDAC treatment or had dose reductions due to AEs. Results: In total, 405 patients (FFX, 197; Gem+NabP, 208) were identified. The proportions of patients who experienced and were treated for any-grade AEs of interest are reported in the Table. Of the AEs of interest, neutropenia resolved most quickly (median time from onset to resolution, FFX: 9.5 days; Gem+NabP: 12.5 days); neuropathy took the longest time to resolve (FFX: 44.0 days; Gem+NabP: 74.0 days). Median time to AE treatment was shortest for nausea and vomiting (both 0.0 days for FFX and for Gem+NabP). Time to treatment was longest for neuropathy (FFX: 158.5 days; Gem+NabP: 70.0 days). Only 5.1% of patients on FFX and 13.4% on Gem+NabP received treatment for neuropathy. Of patients in the FFX group who switched/reduced treatment (n=140), 58.6% received a dose reduction and 7.1% switched to Gem+NabP due to AEs. Conclusions: At the Mayo Clinic sites, incidence of any-grade AEs associated with 1L mPDAC treatment were similar or higher than rates of any-grade or ≥ 2/3–4 grade AEs reported in the literature. Nausea, vomiting and diarrhea were the most commonly treated AEs for both irinotecan-based (FFX) and non-irinotecan-based (Gem+NabP) 1L regimens; neutropenia and neuropathy were less commonly treated. FFX dose reductions were commonly attempted before switching regimens. Proportion experiencing any-grade AE (AE incidence in the literature) Proportion experiencing AE treated for an AE FFX Gem+NabP FFX Gem+NabP Diarrhea 74.6% (50–80%, any grade) 43.8% (< 5%, any grade) 92.5% 56.0% Nausea 81.7% (45%, any grade) 72.1% (20%, grade ≥ 2) 98.8% 96.7% Vomiting 54.8% (10%, any grade) 42.8% (20%, grade ≥ 2) 98.1% 98.9% Neutropenia 58.9% (45%, grade 3–4) 48.1% (12–21%, grade 3–4) 62.1% 46.0% Neuropathy 59.9% (25%, grade 3–4) 32.2% (30%, grade 3–4) 5.1% 13.4%

e16334 Background: Liver cancer remains a leading cause of cancer-related mortality in the United States. Although overall mortality has increased over the past two decades, age-specific patterns and demographic disparities are not fully characterized. Here, we analyzed U.S. liver cancer mortality trends from 1999 to 2023, with a focus on age-related, racial and ethnic, and geographic differences. Methods: Mortality data for U.S. adults aged ≥25 years from 1999 to 2023 were obtained from the CDC WONDER database (ICD-10 codes C22.0–C22.9). Age-adjusted mortality rates (AAMRs) were standardized to the 2000 U.S. population. Joinpoint regression was used to estimate annual percent change (APC) and average annual percent change (AAPC) across age groups, sex, race/ethnicity, U.S. census regions, and levels of urbanization. Results: From 1999 to 2023, overall liver cancer AAMRs increased from 6.95 to 10.1 per 100,000. Marked age-specific differences were observed. Mortality among adults aged 45–54 and 55–64 years peaked in the mid-2010s and subsequently experienced significant declines through 2023 (recent APCs < −4.5% for both groups; P < 0.001). Specifically, while the overall AAPC for the 55–64 age group was +1.89%, mortality significantly reversed after 2016 (APC, −4.59%). In contrast, mortality continued to rise among older adults, including those aged 65–74 years (AAPC, +2.26%), 75–84 years (AAPC, +1.69%), and aged ≥85 years (AAPC, +1.77%) (all P < 0.001). Differences in mortality trends were also identified across racial and ethnic groups. Sustained increases were observed among Non-Hispanic White individuals (AAPC, +1.89%; P < 0.001), while Hispanic/Latino populations experienced declines after 2013 (APC, −0.67%; P = 0.003). Non-Hispanic Black individuals demonstrated a significant decrease in mortality between 2017 and 2020 (APC, −3.82%; P = 0.03). Regionally, liver cancer mortality declined in the Northeast after 2013 (APC, −0.66%; P < 0.001), whereas no significant post-peak declines were observed in the South or West. Conclusions: U.S. liver cancer mortality trends exhibit substantial heterogeneity by age, race and ethnicity, and geographic region. The recent, sharp declines among middle-aged adults (APCs < −4.5%) likely reflect the success of large-scale viral hepatitis screenings and highly effective antiviral therapies, whereas continued increases among older adults may relate to the cumulative impact of metabolic risk factors and delayed diagnosis. Persistent racial and regional disparities highlight the need for targeted, age-specific prevention and surveillance strategies.

e16322 Background: Small intestine neuroendocrine carcinoma (NEC) is a rare, aggressive malignancy comprising less than 0.1% of gastrointestinal cancers. Population-level data remain limited, restricting understanding of long-term survival patterns, demographic disparities, and evolving disease burden. We evaluated survival outcomes, demographic predictors, and incidence trends of small intestine NEC in the United States. Methods: We conducted a retrospective population-based cohort study using SEER Research Data (17 registries, November 2024 submission). Patients diagnosed with malignant small intestine NEC (ICD-O-3 morphology code 9.3.3.1.2) between 2000 and 2022 were identified using SEER*Stat (v9.0.4.2). Variables including age group, sex, race, year of diagnosis, survival time, and vital status were analyzed in R (v4.5.1). Overall survival (OS) was estimated using Kaplan–Meier methods and compared using log-rank testing. Cox proportional hazards models identified independent predictors of OS. Annual case counts were modeled using time-series forecasting to project future incidence. Results: A total of 506 patients were included. Estimated OS was 94.4% (95% CI 92.4–96.4) at 1 year, 88.1% (85.3–91.0) at 3 years, and 82.4% (79.0–85.9) at 5 years, with a subset demonstrating survival beyond 15 years. Increasing age was associated with worse survival (log-rank p = 0.058). Significant racial differences in OS were observed (log-rank p < 0.0001). In multivariable analysis, race remained independently associated with OS. Incidence forecasting projected a modest increase in annual case burden over the next decade. Conclusions: Small intestine NEC demonstrates heterogeneous survival outcomes, significant demographic disparities, and projected growth in disease burden. These findings highlight the need for improved risk stratification, equitable access to care, and integration of molecular and treatment-level data to optimize management of this rare malignancy

e16229 Background: Liver cancer is a leading cause of cancer-related mortality worldwide, with rising incidence linked to metabolic disorders. Conditions such as obesity, diabetes mellitus, and metabolic syndrome contribute substantially to non-viral liver carcinogenesis. However, long-term temporal trends and mortality disparities among adults with metabolic disorders in the United States remain incompletely characterized. Methods: Mortality data for liver cancer among adults with metabolic disorders were obtained from the centers for disease control and prevention (CDC) mortality database. Adults aged 25 years and older were included and age-adjusted mortality rates (AAMRs) per 100,000 were calculated. Temporal trends were evaluated using joinpoint regression and average annual percent change (AAPC) with 95% confidence intervals. Results: From 1999–2023, AAMR for liver cancer in adults with metabolic disorders rose from 0.17 to 0.65 per 100,000 in the U.S., with an overall AAPC of 5.95% [95% CI 5.2–6.7]. Men had higher absolute mortality (0.25→0.93; AAPC 5.68%), while women showed a sharper recent rise (0.11→0.41; AAPC 7.08%), peaking at 11.86% annually after 2016. Hispanic/Latino (0.27→0.89; AAPC 6.73%) and Black populations (0.15→0.75; AAPC 6.15%) experienced steady increases, whereas White mortality accelerated post-2011 (AAPC 9.37%). Regionally, the West had highest rates, the South showed highest growth, and Northeast/Midwest had sharp recent increases. Rural mortality overtook urban by 2020 (0.50 vs. 0.48). Most deaths occurred in medical facilities (48.2%) or home (33.1%), with highest state rates in Hawaii (0.56), Texas (0.47), and Rhode Island (0.47). Conclusions: Mortality from liver cancer in adults with metabolic disorders rose sharply in the U.S. since 1999, with accelerating trends and marked disparities by sex, race/ethnicity, region, and urbanization. These findings highlight an urgent need for targeted metabolic risk reduction and equity-focused prevention strategies.

e16157 Background: Liver cancer mortality remains a major public health burden in the United States despite advances in prevention and treatment. Psychoactive substance use disorder (PSUD) is an increasingly prevalent comorbidity; however, national trends and disparities in liver cancer mortality among adults with PSUD remain poorly characterized. Methods: We conducted a retrospective analysis of liver cancer-related deaths among U.S. adults aged 25 years and older with PSUD from 1999 to 2023 using Centers of Disease Control (CDC) Wide Ranging Online Data for Epidemiological Research (WONDER) mortality database. Age-adjusted mortality rates (AAMRs) were calculated per 100,000 population and stratified by census region, state, urban–rural status, sex, and race/ethnicity. Temporal trends were assessed using Joinpoint regression to estimate average annual percent change (AAPC). Statistical significance was determined using p-value (<0.05). Results: Overall liver cancer related AAMR per 100,000 among adults with PSUD significantly increased from 0.15 in 1999 to 1.02 in 2023 (AAPC: 7.47; 95% CI: 6.33 to 8.61; p < 0.000001). The overall mortality burden was higher in males. However, females experienced larger rises in mortality (AAPC: 10.03; 95% CI: 8.85 to 11.24; p < 0.000001) as compared to males (AAPC: 7.30; 95% CI: 5.78 to 8.84; p < 0.000001). Marked racial disparities were observed, with non-Hispanic Black and non-Hispanic White individuals experiencing the highest mortality rates with persistent increases over time, while Hispanic/Latino populations exhibited modest and variable trends. A substantial geographic variability was observed, with the greatest increases in the Midwest and the South. State-level analysis revealed higher mortality rate in Oregon (1.27) followed by Washington (1.12) and Texas (1.06) respectively. Both rural and urban areas experienced a sharp rise in mortality with AAPC being slightly higher in rural areas (AAPC: 10.34) as compared to urban areas (AAPC: 9.67). Conclusions: Liver cancer mortality among U.S. adults with PSUD has risen markedly over the past two decades, with substantial demographic and geographic disparities. These findings highlight the need for integrated liver cancer screening and substance use disorder interventions targeting high-risk populations.

e16102 Background: Esophageal cancer remains a significant cause of cancer mortality in the United States. While overall trends have been reported, less is known regarding contemporary long-term patterns and specific disparities across demographic and geographic strata. We aimed to characterize esophageal cancer mortality trajectories and identify populations with divergent outcomes by age, race/ethnicity, geographic region, and urbanization status. Methods: We analyzed esophageal cancer mortality data from 1999 to 2023 using the Centers for Disease Control and Prevention (CDC) WONDER database. Age-adjusted mortality rates (AAMRs) were standardized to the 2000 U.S. standard population. Joinpoint regression analysis was utilized to estimate the annual percent change (APC) and average annual percent change (AAPC) with 95% confidence intervals (CIs). Analyses were stratified by age, sex, race/ethnicity, census region, state, and urbanization level. Results: Overall esophageal cancer mortality in the U.S. declined significantly from 1999 to 2023 (AAPC, -0.81%; 95% CI, -0.97% to -0.65%; P < 0.001). Declines were observed across most age groups, with the steepest reductions among adults aged 45-54 years (AAPC, -1.68%; 95% CI, -2.01% to -1.35%) and 55-64 years (AAPC, -1.25%; 95% CI, -1.51% to -0.99%). Marked racial and ethnic disparities were identified. Non-Hispanic (NH) Black individuals experienced the most rapid decline (AAPC, -4.07%; 95% CI, -4.42% to -3.72%). Conversely, trends among NH White individuals remained stable overall (AAPC, -0.05%; P = 0.59), characterized by an initial increase from 1999 to 2005 (APC, 1.14%; P = 0.002) followed by a modest decline from 2005 to 2023 (APC, -0.44%; P < 0.001). Regionally, the West demonstrated the largest decline (AAPC, -1.13%; 95% CI, -1.26% to -0.99%), followed by the Northeast (AAPC, -1.05%). West Virginia was the only state to exhibit a significant increase in mortality (AAPC, 1.01%; 95% CI, 0.38% to 1.64%; P = 0.003). Mortality declined significantly in metropolitan areas (AAPC, -1.09%; P < 0.001), while trends in nonmetropolitan areas remained stagnant (AAPC, 0.48%; P = 0.12). Conclusions: Despite a national decline in esophageal cancer mortality, substantial disparities persist across racial, geographic, and urbanization groups. The dramatic improvement among NH Black populations contrasts with the relative stability in NH White populations and the lack of progress in nonmetropolitan areas. The significant rise in mortality in West Virginia warrants targeted investigation. These findings underscore the critical need for population-tailored strategies to ensure equitable progress in cancer prevention and care.
