ABSTRACT Newly diagnosed patients with non‐Hodgkin lymphoma (NHL) often have a history of other diseases, and these comorbidities can impact patient treatment and management options, as well as overall survival (OS). We developed the Lymphoma Epidemiology of Outcomes (LEO) comorbidity index (LCI) as a sum of 10 comorbidities adapted from the Self‐Report‐Generated Charlson Comorbidity Index (SRG‐CCI) for use in the LEO cohort, a national prospective study of newly diagnosed NHL. Of the 5502 participants with self‐reported comorbidity data, 3107 (56.4%) were male and the mean age at diagnosis was 60.9 years (range, 18–99 years). The LCI ranged from 0 to 6, with 48.6% having 0, 30.2% having 1, 21.2% having 2 or more comorbidities. With a median follow‐up of 62.4 months among surviving participants, 2099 patients had an event and 1219 died. Continuous LCI similarly predicted both 1‐year mortality (c‐statistic = 0.654) and OS (c‐statistic = 0.655), while it showed a weaker but still statistically significant predictive ability for lymphoma‐specific (c‐statistics = 0.617) and event‐free (c‐statistic = 0.574) survival. Participants with 1 (HR = 1.21, 95% CI 1.05–1.39) and 2+ (HR = 1.80, 95% CI 1.56–2.08) comorbidities had inferior OS compared to those with no comorbidities after adjustment for age and sex (c‐statistic = 0.654), and performance strengthened after adjustment for the International Prognostic Index (c‐statistic = 0.672). LCI predicted OS most strongly in marginal zone (c‐statistics = 0.748) and weakest in T‐cell (c‐statistic = 0.579) lymphoma. The cumulative incidence of death due to lymphoma, lymphoma treatment, and other causes all increased with increasing comorbidities, with the greatest increase observed for death due to other causes. The LCI performs comparable to other published comorbidity indices, supporting its use in the LEO cohort to better model real‐world outcomes and more generally providing an approach to implementing comorbidity indices in cancer survivorship cohorts.

Objective: To examine prospective associations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test positivity, coronavirus disease 2019 (COVID-2019) symptom severity, and COVID-2019 hospitalization with incident clinical diabetes among aging women. Methods: A cohort study was conducted using data from 34,405 eligible Women’s Health Initiative participants who completed ≥1 COVID-2019 surveys (Survey 1: June–December 2020; Survey 2: June 2021–February 2022) and were followed up for an average of 1.86 (±0.49) years, yielding 399 incident diabetes cases. Results: SARS-CoV-2 test positivity was associated with diabetes risk in the age-adjusted Cox regression model (hazard ratio [HR] = 1.76, 95% confidence interval [CI]: 1.10, 2.82), but not when fully adjusted (HR = 1.43, 95% CI: 0.88, 2.31). Diabetes risk was higher among those with 1–2 COVID-19 symptoms (HR = 1.39, 95% CI: 1.09, 1.77) and those with 3± COVID-2019 symptoms (HR = 1.53, 95% CI: 1.06, 2.22) compared with those without COVID-2019 symptoms in fully-adjusted models, irrespective of self-reported SARS-CoV-2 testing. COVID-2019 hospitalization was associated with 2–3 times the risk of clinical diabetes in age-adjusted (HR = 2.95, 95% CI: 1.52, 5.72) and fully-adjusted (HR = 1.90, 95% CI: 0.97, 3.72) models. Conclusions: Age-adjusted self-reported SARS-CoV-2 test positivity was associated with a higher incidence of diabetes. Reporting of COVID-2019 symptoms and being hospitalized for COVID-2019 were each associated with higher incidence of diabetes in aging women, after controlling for demographic, socioeconomic, lifestyle, and health characteristics.

406 Background: Anxiety is highly prevalent among oncology patients, often arising from uncertainty around diagnosis, treatment options, and prognosis. Elevated anxiety can impair decision-making, reduce treatment adherence, and diminish overall quality of life. Effective second opinion consultations may help mitigate anxiety and increase patients’ confidence in recommending healthcare services to others. Our study evaluates the impact of oncology second opinion (OSO) consultations on anxiety level (AL) and confidence in the organization (CIO) providing the second opinion, i.e., Cincinnati Cancer Advisors (CCA) and Naples Cancer Advisors (NCA). Methods: The study included patients with cancer diagnoses, age ≥18 years, who were served in person for OSO at CCA and NCA. A survey was used before and after consultation, measuring AL (scale 1- 10) and CIO level (scale 1 - 10), assessed by asking patients how likely they would refer loved ones to the organization. After the content and face validation, patients completed the survey anonymously, put it in a sealed envelope, and dropped it in a dedicated box. Data was analyzed using paired t-tests to compare the change from pre- to post-consultation scores. Spearman’s correlation test was used to assess the relation between the changes in AL and CIO. Statistical significance was assessed using an alpha-level of 0.05. Analyses were conducted via R and R Studio (version 2025.5.1.513). Results: Overall, 46 consecutive patients participated (45 completed AL pre and post visit survey and 43 completed the CIO pre and post visit survey). The mean pre-consultation anxiety score was 5.92 (SD = 2.58), and the post-consultation score was 3.87 (SD = 2.10), demonstrating a significant reduction (mean paired difference = -2.05; p < 0.0001). The mean pre-consult CIO was 8.21 (SD = 2.03), increasing to 9.73 post-consultation (SD = 0.53), indicating a significant improvement (mean paired difference = 1.66; p < 0.0001). The correlation between changes in AL and CIO was not statistically significant, which may be attributed to the high baseline CIO scores (ceiling effect) and the small sample size. Conclusions: Oncology second opinion was associated with a marked decrease in patient AL and a significant increase in CIO. The patient survey will continue to recruit additional participants to increase the sample size and explore the correlation between changes in AL and CIO. Studying the downstream impact on patient experience and outcome is warranted.

Abstract While many postmitotic cells in the body harbor cilia, certain aggressive cancers such as glioblastoma (GBM) display low frequencies of cells harboring a primary cilium. Ciliated GBM cells that plan to multiply have to disassemble their cilium in order for centrioles to duplicate and re-purpose for mitosis. Little is known about the molecular mechanisms underlying cilia disassembly in GBM, or whether this may represent a driving factor in disease onset, progression, or recurrence. In many cell types, ciliary disassembly is thought to be orchestrated by the aurora kinase A (AURKA) and histone deacetylase 6 (HDAC6) signaling axis. These molecules are often overexpressed in GBM, perhaps owing to the less frequent observation of ciliated GBM cells. Here, we review regulators of the core pathway, and discuss recent studies attempting to inhibit AURKA and HDAC6 in patient and mouse models of GBM and resulting effects on cilia. In the face of potent inhibitors, GBM cells appear to engage pathways independent of the core axis to promote cilia disassembly and/or engage other forms of modified axonemal tubulin to ensure persistence of cilia on GBM cells. GBMs upregulate a host of proteins implicated to drive cilia disassembly. Thus, clarifying these alternate mechanisms may be important as the roles of cilia in tumor formation and propagation, angiogenesis, and treatment resistance are increasingly reported. A deeper understanding of the role of cilia in these hallmarks of glioma may hold clues to the high recurrence rate of GBM.

Abstract Chimeric antigen receptor (CAR) T-cell (CAR-T) treatment for B-cell acute lymphoblastic leukemia (ALL) induces high initial response rates, but most patients relapse. Low disease burden (often defined as &lt;5% blasts in the bone marrow) is associated with better outcomes. CAR HEMATOTOX (HT) is a score using prelymphodepletion hematologic and inflammatory parameters to predict outcomes in lymphoma. Here, we assess its prognostic utility in a large multicenter adult B-cell ALL cohort. Patients who received brexucabtagene autoleucel across 33 centers in North America were included as part of the Real-World Outcomes Collaborative of CAR-T in Adult ALL (ROCCA) consortium. An independent cohort of 61 patients with ALL treated with an investigational CD19 CAR-T therapy at 1 center was also described. Among 199 ROCCA consortium patients, 43 (22%) patients with HTlow scores had lower rates of delayed neutrophil recovery than those with HThigh scores (26% vs 52%, P = .002) and fewer severe infections (2.5% vs 18.8%, P = .011). They also had higher response rates, overall survival (OS), and event-free survival (EFS), as well as lower nonrelapse mortality and cumulative incidence of relapse. The survival differences remained significant after multivariable adjustment for disease burden and other covariates. In the investigational cohort of 61 patients, patients with HTlow scores had improved OS and EFS, as well as higher peak CAR-T expansion. In summary, CAR HT score is a prognostic factor independent of disease burden in adult ALL. HTlow score is associated with superior outcomes after CD19 CAR-Ts and higher CAR-T expansion in a single-center cohort. These trials were registered at www.clinicaltrials.gov as #NCT01044069 and #NCT01860937.

Introduction: Percutaneous nephrolithotomy (PCNL) has been a mainstay treatment for large stone burdens since the 1980s, historically offering improved stone-free rates over retrograde intrarenal surgery (RIRS). Gaining optimal access into the renal collecting system can be challenging, requiring advanced skills or interventional radiology assistance. The learning curve for fluoroscopic and ultrasonography access can be steep, with only a minority of PCNL access performed by urologists in the United States. This study compares robotic-assisted electromagnetic (EM) guidance to traditional fluoroscopy for obtaining percutaneous renal access between cohorts of novice and expert urologists. Methods: Ten novices and five expert urologists used robotic-assisted EM guidance to obtain access in a modified supine position compared with using fluoroscopy in a traditional prone position in human cadavers. Primary success was defined as papillary access. Performance metrics, including number of puncture attempts, time to access, radiation exposure, and participant confidence, were compared between novices and experts. Results: Robotic-assisted EM guidance improved success rates for both novices (100% vs 70%) and experts (93% vs 87%) compared with fluoroscopy. Novices showed greater accuracy using robotic assistance (97% vs 37%). The number of insertion attempts decreased with robotic guidance for both groups (novices: 3.42 ± 0.44 vs 1.47 ± 0.19; experts: 2.13 ± 0.36 vs 1.40 ± 0.24; p < 0.002). EM guidance ( p < 0.05) and experience ( p < 0.05) significantly reduced the time from needle insertion to access (novices: 12.86 ± 2.41 minutes vs 4.49 ± 0.96 minutes; experts: 4.90 ± 1.40 minutes vs 4.09 ± 1.12 minutes). Radiation exposure was notably lower with EM guidance (novices, 1.12 ± 0.17 mGy vs 4.86 ± 0.70 mGy; experts, 0.69 ± 0.12 mGy vs 4.11 ± 1.21 mGy; p < 0.001). Novices felt more confident (5[3–5] vs 2[1–4], p < 0.001) and at ease (5[3–5] vs 2.75[1–3], p < 0.001) with EM guidance. Conclusion: Robotic-assisted EM guidance improves percutaneous access success, reduces attempts and radiation exposure, and enhances novice confidence and accuracy. This technology could enable urologists to more effectively and safely perform PCNL, especially for less experienced practitioners.

Purpose: Surgical video review can be used in urologic training, yet significant barriers to the implementation of video review programs exist, and formal assessment of usage and utility for trainees is limited. Here, we evaluate a novel video review platform to describe patterns of use and determine perceived utility. Materials and Methods: We analyzed learning points entered by trainees during video review of radical prostatectomy cases using our surgical intelligence–enabled Film Room platform between September 2023 and July 2024. Learning point content was categorized according to surgical coaching domains as technical, cognitive, nontechnical, or descriptive. Entries were compared by surgical step and level of training. Anonymous surveys were distributed to trainees to determine perceived utility and reveal patterns of video review. Results: Thirteen trainees entered 480 unique learning points across all radical prostatectomy steps and spanning surgical coaching domains during the study period. Learning points varied by training level, with junior trainees entering points more often than senior trainees for Retzius-space dissection ( N = 73 vs 17, p < 0.01) and seminal vesicle and posterior dissection ( N = 58 vs 27, p < 0.01). Trainees used video review in preparation for both upcoming cases and performance analysis. Ninety-four percent of survey respondents reported they either agreed or strongly agreed that video review helped them develop surgical skills. Conclusions: We found usage across training levels and high perceived utility of our Film Room platform for video review of robotic prostatectomy. Implementation of video review platforms holds promise to augment existing urologic training and should be explored further.

Background: Evaluation of otolaryngology resident technical performance has historically relied on subjective perioperative feedback. Despite various assessment tools attempting to provide consistent surgical skill evaluations, current methods remain inherently subjective. Aim: This proof-of-concept pilot study aimed to assess if a 3-dimensional surgical navigation system could capture objective surgical data during endoscopic sinus surgery (ESS). A secondary aim was to analyze if there were any differences between novice and practiced trainees. Methods: Otolaryngology residents performed supervised ESS on patients while their instrument (microdebrider, suction) motion was recorded using a TruDi ® Navigation System. Prior to the surgery, surgical landmarks were defined with sensory beacons in the navigation system using the patient’s preoperative computed tomography (CT) scan. Metrics included time to reach beacons, number of alerts at each beacon, and instrument speed. Results: Fifteen otolaryngology residents performed 87 ESS. The navigation system successfully obtained “time to reach sinus X” data for 64% of sinuses/ case, velocity data in 93% of cases, and number of beacon “alerts” per minute in 93% of cases. We found a significant difference between PGY 3 residents and PGY 4/PGY5 residents in the number of sphenoid sinus alerts per minute ( P = .01) and the percentage of cases in which the resident accessed the maxillary sinus via the natural os ( P < .001). Impact: This study demonstrates the feasibility of collecting objective, navigation-based intraoperative metrics during live surgery and is a first step toward building a comprehensive objective assessment tool in ESS. We hope this report encourages further research into this technology’s application in objective resident skill assessment and correlation with concurrent faculty assessments.

Abstract Background Erectile dysfunction (ED) is a known precursor and sequela of cardiovascular disease (CVD), with ED severity predicting CVD severity. Aim This study aimed to evaluate the utility of ceramide levels in patients with ED. Methods We initiated ceramide testing in all patients with ED. We retrospectively analyzed ceramide levels from electronic records and stratified by severity of symptoms using the erectile function domain of the International Index of Erectile Function (IIEF). Outcomes The study aimed to determine whether abnormal ceramide levels were associated with ED severity and increased cardiovascular risk. Results Three hundred and fifty-four patients were reviewed, of whom 253 (71.5%) had moderate or higher ED. A statistically significant difference in abnormal ceramide values was found in patients with moderate to severe symptoms, and the odds of getting an abnormal ceramide test were increased based on the IIEF scoring alone (odds ratio [OR] 2.3 [1.04-5.12]; P-value = .034). Clinical Implications Serum ceramide testing could be beneficial in identifying cardiovascular risk in men with ED, potentially prompting cardiac referrals and lifestyle modifications. Strengths and Limitations The strengths of this study include a large sample size and the use of a well-established scale, while the limitations include the retrospective nature of the study and the need for further research to validate the findings. Conclusion Patients undergoing management for ED may benefit from serum ceramide testing and subsequent cardiac referral.

Abstract BACKGROUND Glioblastoma (GBM) is highly aggressive with poor prognosis, especially in recurrent cases where treatments are limited. Intra-arterial (IA) Yttrium-90 (Y90) microsphere therapy, CE-marked for hepatic neoplasia, offers the potential for targeted high-dose beta radiation in GBM by leveraging tumor hypervascularity. The FRONTIER trial evaluated the safety and feasibility of IA Y90-glass microsphere treatment for recurrent GBM. MATERIAL AND METHODS FRONTIER is a prospective, single-arm, multi-center study with Investigational Device Exemption approval from the US FDA. This initial cohort included patients with recurrent GBM in non-dominant, non-eloquent regions after 1-2 lines of prior therapy. The primary endpoint was the 30-day incidence of treatment-related toxicities (primarily ≥grade 3 non-hematologic, with exclusions). Secondary endpoints included overall treatment-related adverse events (AE), neurological function changes, technical success, and efficacy measures. Treatment regions, defined via cerebral angiography-MRI fusion to cover the recurrent lesion were targeted with 40±4Gy. Post-treatment evaluations included MRI, Y90-PET for absorbed dose distribution, and serial neurological assessments. Changes in post-contrast T1-enhancing tissue volume (T1C-vol) were tracked longitudinally. RESULTS Twelve subjects (67% male; average age 57 years) were treated. The procedure was well-tolerated with no limiting toxicities reported or device-related AEs reported. Five patients experienced 8 procedure-related AEs (6 Grade 1, 2 Grade 3). At discharge one day after treatment, there was no decline in neurologic status per NIHSS. Technical success was 100%, with post-treatment Y90-PET showing a median absorbed dose of 41.5 Gy (range 39.2-45.4) to the treatment region (median volume 80.3 cc [40.9-118.5]). The median tumor absorbed dose was significantly higher at 124.2 Gy (range 58.5-508.5) within a median tumor volume of 5.8 cc (range 0.5-55.4), indicating preferential tumor perfusion. At 1 month, the best response was partial response in 17% (2/12), stable disease (SD) in 67% (8/12), and progressive disease in 17% (2/12). At 2 months, 73% (8/11 evaluable) had SD, and 33% (4/12) showed reduced T1C-vol within the treated area. Median progression-free survival was 3.0 (95% CI 1.1-3.7) and median overall survival (OS) was 9.3 months (95% CI 5.0-NE) from Y90 treatment. Exploratory analysis revealed a significant OS benefit for patients receiving a tumor absorbed dose above the median (&gt;124 Gy) compared to those below (13.1 vs 5.8 months, p=0.0054). CONCLUSION Results from this initial cohort of the FRONTIER trial suggest IA Y90 glass microsphere therapy is technically feasible and well-tolerated in patients with recurrent GBM. The observed dose-response relationship warrants further investigation of this modality as a potential treatment option.
