Abstract Background Immigrants to the United States often face challenges from limited healthcare access and less healthy environments which contribute to rising obesity and cardiovascular risk. Purpose To assess the feasibility and effectiveness of a community-based social network intervention for cardiovascular risk reduction among Hispanic and Somali adults. Methods A social network-informed, community-based participatory research-derived health promotion intervention was delivered by Hispanic and Somali lay health promoters (HPs) to members of their social networks over 1 year (12 biweekly sessions in months 0-6; 12 biweekly check-ins in months 7-12). Using a closed-cohort stepped wedge cluster randomized design, social networks were randomly assigned to receive the intervention immediately or after a delay of 1 year. Measurements at baseline, 6 months, and 12 months were derived from 6 of the American Heart Association’s “Life’s Simple 7”: BMI, blood pressure, fasting glucose, cholesterol, physical activity and dietary quality (range 0-12, with higher values indicating lower cardiovascular risk). Waist circumference and proportion of participants who achieved >5% body weight loss were also assessed. Results Four hundred seventy-five participants were enrolled among 51 HPs (29 Hispanic; 22 Somali). There was a statistically significant improvement in cardiovascular risk in the intervention group (n = 246) compared with controls (n = 229) at 6 months (0.4 [1.8] vs. −0.1 [1.7]; P = .03) that was not sustained at 12 months (0.5 [1.9] vs. 0.3 [1.8]; P = .38). There was a statistically significant higher proportion of participants who lost >5% of body weight in the intervention group compared with controls at 12 months (37% [15] vs. 18% [7.9]; P = .02). Reductions in weight and waist circumference in the intervention group compared with controls did not achieve statistical significance. Conclusion A social network intervention, delivered by lay HPs was feasible and resulted in a modest improvement of cardiovascular risk and clinically significant weight loss.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Non-Small Cell Lung Cancer (NSCLC) provide recommendations for the treatment of patients with NSCLC, including diagnosis, primary disease management, surveillance, and subsequent treatment. The panel has updated the list of recommended targeted therapies based on recent FDA approvals and clinical data. This selection from the NCCN Guidelines for NSCLC focuses on treatment recommendations for advanced or metastatic NSCLC with actionable biomarkers.

Abstract Background Anti‐M antibodies were described as rarely eliciting hemolytic disease of the fetus and newborn (HDFN) in pregnancy. More recent literature, primarily from Asia, reports severe HDFN attributed to maternal anti‐M. The objective of this study is to determine if there is a difference in the frequency and/or severity of anti‐M HDFN among subjects who self‐report as Asian compared to non‐Asian. Methods Retrospective data were collected from 18 sites. Fetuses/neonates affected by HDFN were categorized as unaffected, mild, moderate, or severe based on clinical management and outcomes. Results Anti‐M was identified in 557 obstetric patients. Among 332 neonates with complete data for analysis, anti‐M was detected in isolation during the pregnancies of 210 (63.3%) neonates; 198 (94.3%) were unaffected by HDFN. The overall frequency of HDFN was 6.5% (2/31) in Asian patients and 5.6% (10/179) in non‐Asian patients. The frequency of severe HDFN was 6.5% (2/31) among Asian patients and 0.6% (1/179) among non‐Asian patients. Among non‐Asian patients, eight (4.5%) were mild and one (0.6%) was moderate. Of 63 pregnancies with anti‐M and ABO incompatibility, 6 (9.5%) were associated with mild HDFN and 57 (90.5%) were unaffected. Of 49 pregnancies with anti‐M and non‐ABO antibody(s), 6 (12.2%) were associated with mild HDFN and 43 (87.8%) were unaffected. One case (10.0%) of HDFN (mild) occurred in the presence of anti‐M, additional antibody(s), and ABO incompatibility. Conclusion In this study, severe anti‐M HDFN was rare in non‐Asian subjects. There is a signal that Asian patients are at greater risk for severe anti‐M HDFN.

ABSTRACT The epidemiology of myelodysplastic syndromes/neoplasms (MDS) is challenging to define due to inconsistent reporting, complex diagnostic procedures, and evolving diagnostic criteria. Using the National MDS Natural History Study—a prospective cohort with centrally adjudicated histopathology and genetic variant review—we characterized the landscape of MDS across the United States and identified differences across demographics. Among 2115 participants, 64% (1346) had an MDS spectrum condition, including MDS (24%), MDS/myeloproliferative neoplasm (5%) and precursor conditions—clonal cytopenia of undetermined significance (22%) and idiopathic cytopenia/dysplasia of undetermined significance (13%). The median age was 74 years, and participants were predominantly male (66%), White (91%), and Non‐Hispanic (92%). Myeloid‐associated variants were detected in 68% of participants, most commonly in TET2, DNMT3A, ASXL1, SF3B1, and SRSF2 . Black, compared to White, participants were younger at diagnosis (69 vs. 74 years, p = 0.01), had equal or increased prevalence of higher‐risk MDS, lower hemoglobin, and higher peripheral blood blasts, yet were less likely to receive MDS‐directed therapy (14% vs. 42%, p = 0.008). Black and Hispanic participants had fewer detectable gene mutations than White participants. Females had lower variant allele frequencies and fewer RNA splicing gene mutations than males. After multivariable adjustment, TP53 mutations, MDS diagnosis, and higher‐risk disease were associated with worse progression‐free and overall survival; age was also associated with overall survival. Black race trended toward improved progression‐free survival. These findings highlight the need for enhanced understanding of MDS pathogenesis across patient groups and refined prognostic tools to improve personalized management of MDS spectrum conditions.

Background: Sharing of family cancer history (FCH) in Black families has been documented as lower than in other populations. There has been limited exploration as to the factors and circumstances that facilitate or hinder FCH communication in these communities. Objective: To explore intersecting factors influencing FCH discussion in Black families with a breast or ovarian cancer diagnosis. Interventions/Methods: We conducted qualitative interviews with socioeconomically diverse breast and ovarian cancer patients or family members. Interviews were thematically analyzed for iterative themes on FCH. Results: A total of 107 participants completed an interview. Discussion of FCH was reported as being influenced by several factors, including relationship and family dynamics, personality of family members, involvement in caregiving and support, and perceived importance and responsibility of communicating FCH for cancer prevention. Participants also described how inequitable access to medical care influenced disclosure of a cancer diagnosis, and socioeconomic concerns can influence family communication and documentation of FCH in the medical record. Conclusion: Our analysis indicates that disclosure of FCH is improving over time as access to healthcare has increased for Black families. Implications for Oncology Nursing Practice: Strategies to collect FCH outside of clinic settings, such as digital tools or chatbots, should be considered for increased capture of cancer pedigrees in families where discussion is limited. Patient education on options for preventative care and communications tools may assist patients with family discussions, although patients with adverse social determinants of health are likely to experience additional barriers to genetic screening based on FCH alone.

Abstract Purpose: Knowledge of prognostic factors and long-term survival in patients with diffuse hemispheric glioma, H3 G34–mutant (DHG, H3 G34), remains limited in this tumor with a poor prognosis. Experimental Design: This retrospective, multi-institutional study investigated prognostic variables for patients with DHG, H3 G34, and their association with progression-free survival (PFS) and overall survival (OS). Uni- and multivariable Cox proportional hazard models were applied with multiple imputed datasets. Results: A total of 153 patients (142 G34R, 9 G34V, 2 via DNA methylation) were included. The median age at diagnosis was 17 years (range, 2–45). Initial gross/near total resection (GTR/NTR) was achieved in 43% of patients. Radiation was given in 91% (85% focal irradiation), and initial chemotherapy was given in 87% [70% temozolomide-based (TMZ), 25% TMZ/lomustine, 5% non-TMZ]. Median OS was 24 months [interquartile range (IQR), 22–28] with a median PFS of 14 months (IQR, 12–19). Twelve patients (8%) were found to be long-term survivors (≥5 years). Exploratory multivariable analysis showed that adjuvant radiotherapy [HR, 0.076; 95% confidence interval (CI), 0.033–0.17] and achieving GTR/NTR compared with < NTR (HR, 0.51; 95% CI, 0.33–0.78) were associated with improved PFS. Multivariable analysis showed improved OS with increasing age at diagnosis (HR, 0.70; 95% CI, 0.57–0.87), initial radiotherapy (HR, 0.38; 95% CI, 0.15–0.96), and initial GTR/NTR compared with < NTR (HR, 0.60; 95% CI, 0.37–0.97). Conclusions: This cohort highlights prognostic factors for patients with DHG, H3 G34, and describes relapse patterns and therapy approaches. Clinical trials and prospective registries are needed to improve outcomes.

ABSTRACT Introduction Breast cancer remains a leading cause of death among Latinas. Although breast cancer risk assessment models exist and show promise in reducing mortality, few studies have elicited women's interest in and perceptions around breast cancer risk assessment, particularly among underserved populations, like Latinas, who are susceptible to disparities in breast cancer outcomes. These disparities stem from factors such as limited access to healthcare services, lower rates of screening utilization, language barriers, and socioeconomic challenges, all of which compound their risk and hinder effective engagement with risk assessment tools. This qualitative study aims to explore Latinas' perspectives regarding breast cancer risk assessment and implications on future behaviors. Methods Twenty‐three under‐ or uninsured Latinas aged 45–65 with no personal history of breast cancer took part in either a focus group ( n = 3, 15 participants) or individual interviews (8 participants). Guided by health behavior theories (Theory of Planned Behavior and Health Belief Model), data were transcribed, translated, and analyzed using a deductive‐inductive approach to thematic content analysis, resulting in four themes. Results Latinas expressed high interest in knowing their breast cancer risk and reported that the benefits of knowing one's risk outweighed the harms. Latinas also stated that they would continue screening as recommended if found to be at low risk, but that they would speak with their provider or increase screening frequency if found to be at increased risk. Moreover, Latinas described the pivotal role of providers and social networks in influencing interest and perceptions around breast cancer risk assessment and preventive behaviors. Conclusion Underserved Latinas viewed breast cancer risk assessment positively and underscored the need for multilevel, culturally tailored strategies to improve breast cancer risk assessment. This study yielded four distinct themes: (1) Interest and Awareness of Personal Breast Cancer Risk, (2) Benefits and Barriers of Knowing Personal Breast Cancer Risk, (3) Screening Implications of Knowing Personal Breast Cancer Risk, and (4) Provider Influence on Breast Cancer Risk Assessment and Behaviors. Potential strategies include efforts to improve provider engagement and communication and leveraging social networks to increase awareness and encourage preventive behaviors.

Abstract Introduction Cancer clinical trials have historically faced challenges in achieving fully representative trial population, particularly in terms of including patients from diverse ethnic and racial groups, those with low socioeconomic status, and those living in rural regions. This has contributed to inequities in access to novel therapeutic options. Background The I-SPY adaptive platform trials have prioritized diversity since inception, consistently enrolling in >10% of trial patients being Black and/or Hispanic individuals. The majority of participating institutions in the I-SPY 2.2 study are academic or large well-resourced health systems. In 2023, the I-SPY ACCESS (Achieving Cancer Clinical Trial Equity in Socioeconomically Diverse Sites) Initiative was launched to enhance representation by engaging and involving nontraditional trial sites- such as safety-net hospitals, community cancer centers, and rural cancer centers- that serve historically excluded patient populations. Methods The I-SPY ACCESS Initiative offers customized and personalized tailored support to under-resourced sites. This includes comprehensive feasibility and readiness assessments, onboarding guidance, enhanced site-specific training, centralized institutional review board (IRB) navigation, site peer mentorship, and educational materials for both patient and provider. Additionally, patients gain access to I-SPY advocate peer trial navigators. Sites are provided culturally responsive patient education tools- including multilingual brochures, a dedicated patient website, and content co-developed with community partners. A Clinical Trial Navigator supports both patients and sites, helping to locate logistical, social, and trial specific resources.Tools such as virtual Clinical Research Coordinators (vCRC's) and OneSource technology are deployed strategically based on assessed site need and resource availability. OneSource is an innovative platform that enables direct extraction of clinical data from electronic health records into trial databases, reducing site workload and improving data quality. Funding models are currently being explored to extend OneSource and vCRC services across more ACCESS sites. In the future, there are plans to pilot financial navigation services and integrative care resources for all patients enrolled in I-SPY with particular focus on those enrolled at ACCESS sites. Results and Progress As of June 2025, seven sites have been assessed as ACCESS sites for I-SPY 2.2, with two sites having successfully completed activation and currently enrolling participants. Beginning in mid-2024, one DCIS RECAST ACCESS site has been activated and 11 additional sites are in the onboarding process. The modest pace of I-SPY 2.2 activation reflects the complexity and operational demands associated with resource-intensive platform trial. In contrast, the DCIS RECAST protocol was designed with a lower burden, facilitating easier implementation by under-resourced sites, reflected by increased interest in the study among ACCESS sites. The ACCESS framework is being explored for potential future application in the Pre I-SPY Phase 1 platform trial, particularly considering the historical underrepresentation of such sites in the early-phase clinical research. Conclusion and Future Goals The I-SPY ACCESS initiative demonstrates that investing in thoughtful, innovative, and effective means for trial delivery, as well as incorporating community-based support, can strengthen representation in complex, adaptive breast cancer trials. The initiative offers a flexible, equity-driven framework that is impactful now and scalable for future innovation in oncology research. Citation Format: S. L. Horton, D. A. Idossa, K. C. Hewitt, J.

Abstract Background: Survivor plots permit adjustment by baseline demographics and clinical characteristics; log-normal survival analysis may be more robust than a Cox model under departures from model assumptions. We depicted distant disease-free survival (DDFS) for statistically standardized quantitated ER, PgR, and HER2. Methods: We utilized CCTG MA.27 (NCT00066573), an adjuvant phase III trial of exemestane versus anastrozole in postmenopausal women with ER+ and/or PgR+ tumours. IHC ER, PgR, and HER2 HSCORE were centrally assessed by machine image quantitation, and statistically standardized to mean of 0, standard deviation (SD) of 1 following Box-Cox variance stabilization transformations of square for ER, natural logarithm (ln) and square root for PgR, and ln for HER2. For the ln transformation, 0.1 was added to 0 HSCOREs for a stable transformation. The primary endpoint was DDFS at the longest trial follow-up of 4.1 years. For log-normal survival analysis, ln(time) is a linear function of covariates and had a normal distribution; the Cox models were log-linear for covariates. Survival was depicted with log-normal and Cox survivor plots adjusted at the means of age, T and N stage, grade, lymphovascular invasion, treatment, and baseline patient demographics. We examined ER and PgR ASCO/CAP cut-points at (0; >0), HER2 cut-points at (IHC 0, 0 stain; IHC 0, (0,10%] stain; IHC 1+; IHC 2+; IHC 3+), and ER/PgR/HER2 standardized cut-points at standard deviations about mean of 0 (<-1; (-1,0]; (0,1]; >1). P was based on the likelihood ratio criterion (∼Χ2 (1)) for the addition of ER/PgR/HER2 to the model of baseline covariates, and had nominal significance if P<0.05. Log-normal and Cox multivariable regressions with unstandardized and standardized categorical, and continuous, ER, PgR, and HER2 were adjusted by baseline covariates; 2-sided Wald tests had nominal significance if P<0.05. Results: Of 7576 MA.27 patients, 2325 patients had quantitated image analysis assessments for ER, PgR, and HER2; 113 of 2325 (4.9%) patients experienced a DDFS event during follow-up. Multivariable log-normal survival analysis indicated DDFS was significantly longer for patients with T1 (p=0.01), N0 (p=.002), and grade 1/2 tumors (p=0.01); similar significance levels were found with a Cox model. Log-normal survivor plots were smooth, while Cox survivor plots were step-wise discontinuous at events. Adjusted log-normal survivor plots indicated similar 5-year DDFS for patients by standardized ER categories (p=0.43): 95.4% for those with ER <-1.0 (n=401); 95.8%, for (-1.0,0.0] (n=737); 96.1%, for (0.0,1.0] (n=737); and 96.4%, for >1.0 (n=450). The log-normal standardized PgR survivor plots indicated patients had significantly different 5-year DDFS (p<.001) by categories, with both ln and square root transformations of HSCORE: with a ln transformation, 93.7% for <-1.0 (n=607); 95.4%, for (-1.0,0.0] (n=390); 96.8%, for (0.0,1.0] (n=826); and 97.8%, for >1.0 (n=502). Patients had similar 5-year DDFS by standardized HER2 categories (p=0.71): 96.2% for <-1.0 (n=83); 96.0%, for (-1.0,0.0] (n=1201); 95.9%, for (0.0,1.0] (n=527); and 95.7%, for >1.0 (n=514). In full fit multivariable log-normal survival analyses, DDFS was not significantly different for ER (p=0.51-0.89) and HER2 (p=0.12-0.98); higher PgR was associated with significantly better DDFS (p=0.01 to <.001). Adjusted Cox survival analyses had similar results. Conclusions: Survivor plots adjusted for baseline demographic and clinical characteristics provided similar indications of significance for standardized ER, PgR, and HER2 as those seen in multivariable models with both log-normal and Cox survival analyses. Higher PgR was associated with significantly better DDFS. Citation Format: J. W. Chapman, J. Bayani, S. SenGupta, J. M. S. Bartlett, T. Piper, M. A. Quintayo, S. Virk, P. E. Goss, J. N. Ingle, M. J.
