Abstract Background People of color (POC) and patients (pts) from socioeconomically disadvantaged backgrounds often face financial, geographic, and systemic barriers, limiting access to advanced treatments (Tx). A survey was conducted to better understand how race and socioeconomic factors affect pt awareness of and access to bispecific antibodies (BsAbs) and chimeric antigen receptor T-cell (CAR-T) therapies in the US. Methods This study used 30-minute online surveys (March-June 2024) of 1301 pts with RRMM across 7 countries. Results were analyzed using descriptive statistics and χ2 tests, with P<.01 for all comparisons unless specified; these are presented for the 305 US pts. Results The 305 US pts identified as White (n=227) or POC (n=78), which included Black/African American (n=42); Hispanic/Latino (n=24); and Asian, Pacific Islander, or Arab (n=12). Pts self-reported as having easy/very easy (n=92), neutral (n=117), or difficult/very difficult (n=96) financial burden, being employed (n=142) or not employed (n=163), and having ≤secondary (n=72) or >secondary education (n=232). In the US, more POC reported difficult/very difficult financial circumstances than White pts (47% v 26%). Fewer POC stated they were in remission (28% v 49%) or had consulted an MM specialist (41% v 59%, P=.028), even after adjusting for self-reported good financial circumstances. Among pts with neutral-very easy financial situations, stated remission rates were still lower for POC (n=41) v White pts (n=168) (34% v 59%, P=.026), as were MM specialist visits (41% v 66%, P=.022). Pts with >secondary education (n=232) and those who were employed (n=142) had higher stated remission rates than those with ≤secondary education (n=72) and those who were not employed (n=163) (47% v 32%, P=.025 and 66% v 24%, respectively). Physical burden was experienced by more POC v White pts (91% v 66%), even after adjusting for financial circumstances (90% v 65%, P=.011, for POC v White pts in neutral/very easy financial circumstances). POC and pts with difficult financial circumstances (including POC and White pts) perceived their Tx as less effective than expected across several measures, including emotional and mental health, overall impact on daily life, side effects, Tx costs, and the effect of Tx schedule on everyday life. Awareness of BsAbs and CAR-T was lower among POC v White pts (BsAb: 49% v 77%; CAR-T: 67% v 81%, P=.032), pts who were not employed v employed (BsAb: 63% v 77%, P=.015; CAR-T: 74% v 81%, P=.046), pts with ≤secondary v >secondary education (CAR-T only: 75% v 78%, P=.021), and those in difficult/very difficult v easy/very easy financial circumstances (BsAb: 54% v 90%; CAR-T: 64% v 90%). Among pts aware of BsAbs, 18% (n=39) reported that the Tx was offered by their physician. More employed v not employed pts were offered BsAbs (26% v 10%). There were non-statistically significant differences in the proportion offered BsAbs based on race (POC 8% v White pts 21%, P=.065), financial status (difficult/very difficult 15% v easy/very easy 23%, P=.288), or level of education (≤secondary education 15% v >secondary education 20%, P=.428). Among pts aware of CAR-T, 24% (n=56) reported that the Tx was offered by their physician. Fewer POC than White pts were offered CAR-T (6% v 29%), even after adjusting for financial status (10% v 32%, P=.04 for pts with good finances). Among those aware of CAR-T, fewer pts not employed v employed (12% v 37%), pts with ≤secondary v >secondary education (11% v 27%, P=.015), and pts with financial burden (difficult/very difficult 10% v easy/very easy 31%) were offered CAR-T. Overall, fewer POC received CAR-T than White pts (1.3% v 10.7%, P=.03). Additionally, more employed v not employed pts received CAR-T (15.2% v 2.5%) or BsAbs (23.5% v 4.4%). Conclusions Consistent with existing health equity inequalities (Chen et al, Int J Equity Health, 2025), POC and pts in poorer socioeconomic circumstances had less awareness of and access to BsAbs and CAR-T. To address these disparities, partnering with trusted messengers and pt advocacy groups supporting Black, Hispanic, and Asian pts and those with socioeconomic hardships can enhance healthcare infrastructure, support initiatives to help pts navigate advanced Tx options, and develop pt- and physician-targeted education. These strategies can improve awareness and promote Tx equity, ultimately ensuring that all pts with MM receive optimal care regardless of their socioeconomic status and race.

AbstractSurveillance of individuals at high‐risk of pancreatic cancer using CAPS criteria and other expert consensus guidelines may result in earlier pancreatic cancer detection in some cases; therefore, clinicians are responsible for appropriately identifying and referring these individuals to appropriate high‐risk pancreas cancer screening programs. This study aimed at assessing the perspective, knowledge, and clinical practices of cancer genetic counselors surveyed nationwide towards identification of individuals at high‐risk of pancreatic cancer and utilization of high‐risk pancreatic cancer screening programs. One hundred and eighty‐nine genetic counselors who listed “Cancer” as their specialty on the NSGC website responded to the survey, which consisted of multiple practice‐based, knowledge‐based, and clinical vignette‐based questions. Almost 70% of the genetic counselors surveyed accurately identified when an individual would be considered for high‐risk pancreatic cancer screening, when using 2019 CAPS consensus guidelines as a benchmark. Access to high‐risk pancreatic cancer screening programs and increased provider comfort in counseling individuals at high‐risk of pancreatic cancer were found to be statistically associated in accurate identification of high‐risk individuals in three of the clinical vignettes. Additionally, 60% of genetic counselors reported the majority of high‐risk individuals accept a referral for pancreatic cancer screening, which shows a high uptake of patients accepting referrals from genetic counselors. Genetic counselors have high accuracy in determining who is eligible for high‐risk pancreas screening; thus, they are the ideal providers for initiating referrals to high‐risk pancreatic cancer screening programs. Genetic counseling programs and high‐risk pancreatic cancer screening programs should establish a close working relationship to optimize the identification and subsequent referrals of high‐risk individuals eligible for pancreas cancer screening.

INTRODUCTION: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is frequently used to risk-stratify pancreatic cystic lesions (PCLs). Rising PCL incidence and developments in tissue acquisition and specimen analysis necessitate updated appraisal of EUS-FNA safety, particularly the risk of postprocedure pancreatitis, the most common EUS-FNA-related adverse event. Our systematic review aims to accurately quantify the risk of EUS-FNA-related pancreatitis to best inform decisions regarding EUS-FNA's optimal role in PCL workup. METHODS: We performed systematic searches in 4 databases from inception to April 2024 for original English-language studies investigating EUS-FNA-related pancreatitis. We extracted data on demographics and EUS-FNA-related pancreatitis risk, severity, and risk factors. These were meta-analyzed through the DerSimonian Laird Method using a random-effects model. Meta-regression of pancreatitis risk was performed to delineate associations with clinical and procedural characteristics. RESULTS: Sixty-four studies comprised 8,086 patients and reported 110 EUS-FNA-related pancreatitis events. Pooled risk of EUS-FNA-related pancreatitis was 1.4% (95% confidence intervals, −0.8% to 3.5%; I 2 = 0.00), which was predominantly of mild severity (67%) and uniformly nonfatal. Pancreatitis risk lacked significant association with sample size, age, sex, cyst size, needle caliber, or passes, although we noted trends toward higher risk in studies published after 2015, those using higher gauge needles (19 G vs 22 G/25 G), and those performing EUS-guided through-the-needle biopsy. DISCUSSION: We note with high certainty that pancreatitis after EUS-FNA of PCLs is infrequent and mild in severity with no mortality in the included cohort. EUS-guided through-the-needle biopsy may serve as a significant risk factor for EUS-FNA-related pancreatitis risk; however, further studies are needed to delineate other predisposing characteristics.

689 Background: Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal cancer typically discovered at incurable stages. The PRECEDE Consortium was established to accelerate early detection by using a large-scale, collaborative, innovative model, predicated on standardized collection of demographic, clinical, and imaging data from high-risk individuals (HRI). Here we report the initial pancreas imaging findings in Cohort 1, representing HRI with familial pancreatic cancer (FPC) or pathogenic germline variants (PGV) in PDAC susceptibility genes with a 1 st or 2 nd degree relative with PDAC. Methods: The PRECEDE Consortium (NCT04970056) began enrollment in 5/2020. HRI enrolled prospectively at centers worldwide into one of 7 cohorts based on personal and/or family history of PDAC and PGV status. PRECEDE’s planned enrollment is 10,000 patients. Data sharing is required to join PRECEDE, facilitated by a standardized data collection system and central database (PRECEDELink). Imaging (MRI/MRCP and EUS) is performed using standardized image acquisition and reporting templates. Imaging and clinical sequencing data are stored and analyzed in the PRECEDE data cloud. Results: By 9/16/2022, 26 sites enrolled 3156 patients in 7 cohorts, with 1716 in Cohort 1. Cohort 1 was 60% female, 80% white; 48% met FPC criteria, and 52% were PGV carriers. Within Cohort 1, 658 FPC and 965 PGV (1353 total, 79%) underwent imaging (68% MRI; 32% EUS). Overall, 573/1353 (42%) had pancreas abnormalities: 320/573 (49%) FPC, and 253/573 (36%) PGV (OR [95% CI] 1.65 [1.32–2.06], P < 0.001). Cysts were the most common abnormality, present in 549/1353 (41%) and accounting for 310/320 (97%) FPC and 239/253 (94%) PGV HRI abnormalities. Of 549 HRI with cysts, 262 (48%) had 1 cyst, including 137/310 (44%) FPC and 125/239 (52%) PGV HRI (OR 1.43 [1.07–1.92], P = .012) The remaining 287/549 (52%) had ≥2 cysts, including 173/310 (56%) FPC and 114/239 (48%) PGV HRI (OR 1.98 [1.49–2.64], P < 0.001). Worrisome features occurred in 83/1353 (6.1%) including: 14 (1%) cyst > 2 cm, 7 (0.5%) cyst ≥3 cm, 35 (2.6%) main pancreatic duct (MPD) diameter ≥5 mm; 2 (0.15%) duct strictures; and 25 (1.8%) solid masses. Solid masses included 1 (0.07%) PDAC, 9 (0.7%) neuroendocrine tumors, and 15 (1.1%) benign lesions (e.g. lipoma, splenule). Conclusions: Pancreatic abnormalities are common in a cohort of 1353 HRI enrolled in PRECEDE; 6.1% of HRI had findings with worrisome features and clinical implications. Multiple cysts were significantly more common in FPC HRI (OR 1.98); worrisome findings did not differ between FPC and PGV groups. The longitudinal study of this growing HRI cohort with standardized imaging and matched comprehensive epidemiological, clinical, and laboratory data, along with germline testing, will provide critical information and understanding of PDAC risk, and augment existing clinical decision-making models governing surveillance and treatment.

AbstractBackgroundIdentifying branch‐duct intraductal papillary mucinous neoplasms (BD‐IPMNs) at lowest risk of progression may allow for a reduced intensity of surveillance.ObjectiveWe aimed to externally validate the previously developed Dutch‐American Risk stratification Tool (DART‐1; https://rtools.mayo.edu/DART/), which identifies cysts at low risk of developing worrisome features (WFs) or high‐risk stigmata (HRS).MethodsThree prospective cohorts of individuals under surveillance for BD‐IPMNs were combined, independent from the original development cohort. We assessed the performance (discrimination and calibration) of DART‐1, a multivariable Cox‐proportional logistic regression model with five predictors for the development of WFs or HRS.ResultsOf 832 individuals (mean age 77 years, SD 11.5) under surveillance for a median of 40 months (IQR 44), 163 (20%) developed WFs or HRS. DART‐1's discriminative ability (C‐statistic 0.68) was similar to that in the development cohort (0.64–0.72) and showed moderate calibration. DART‐1 adequately estimated the risk for patients in the middle risk quintile, and slightly underestimated it in the lowest quintiles. Their range of predicted versus observed 3‐year risk was 0%–0% versus 0%–3.7% for Q1; 0.3%–0.4% versus 3%–11% for Q2; and 2.6%–3% versus 2.4%–9.8% for Q3. The development of WFs or HRS was associated with pancreatic cancer (p < 0.001). Vice versa, in absence of WFs or HRS, the risk of malignancy was low (0.3%).ConclusionsThe performance of DART‐1 to predict the development of WFs or HRS in BD‐IPMN was validated in an external international cohort, with a discriminative ability equal as in the development cohort. Risk estimations were most accurate for patients with BD‐IPMNs in the middle risk quintile and slightly underestimated in the lowest quintiles.

OBJECTIVES: Pancreatic cystic lesions (PCLs) may be precancerous. Those likely to harbor high-grade dysplasia (HGD) or pancreatic cancer (PC) are targets for surgical resection. Current algorithms to predict advanced neoplasia (HGD/PC) in PCLs lack diagnostic accuracy. In pancreatic tissue and cyst fluid (CF) from PCLs, we sought to identify and validate novel methylated DNA markers (MDMs) that discriminate HGD/PC from low-grade dysplasia (LGD) or no dysplasia (ND). METHODS: From an unbiased whole-methylome discovery approach using predefined selection criteria followed by multistep validation on case (HGD or PC) and control (ND or LGD) tissues, we identified discriminant MDMs. Top candidate MDMs were then assayed by quantitative methylation-specific polymerase chain reaction on archival CF from surgically resected PCLs. RESULTS: Of 25 discriminant MDMs identified in tissue, 13 were selected for validation in 134 CF samples (21 cases [8 HGD, 13 PC], 113 controls [45 ND, 68 LGD]). A tree-based algorithm using 2 CF-MDMs ( TBX15 , BMP3 ) achieved sensitivity and specificity above 90%. Discrimination was significantly better by this CF-MDM panel than by mutant KRAS or carcinoembryonic antigen, with areas under the receiver operating characteristic curve of 0.93 (95% confidence interval: 0.86–0.99), 0.71 (0.57–0.85), and 0.72 (0.60–0.84), respectively. Cutoffs for the MDM panel applied to an independent CF validation set (31 cases, 56 controls) yielded similarly high discrimination, areas under the receiver operating characteristic curve = 0.86 (95% confidence interval: 0.77–0.94, P = 0.2). DISCUSSION: Novel MDMs discovered and validated in tissue accurately identify PCLs harboring HGD/PC. A panel of 2 MDMs assayed in CF yielded results with potential to enhance current risk prediction algorithms. Prospective studies are indicated to optimize and further evaluate CF-MDMs for clinical use.
