PURPOSE Patient-centered outcomes (PCOs) are pivotal in cancer treatment, as they directly reflect patients' quality of life. Although multiple studies suggest that factors affecting breast cancer–related morbidity and survival are influenced by treatment side effects and adherence to long-term treatment, such data are generally only available on a smaller scale or from a single center. The primary challenge with collecting these data is that the outcomes are captured as free text in clinical narratives written by clinicians. MATERIALS AND METHODS Given the complexity of PCO documentation in these narratives, computerized methods are necessary to unlock the wealth of information buried in unstructured text notes that often document PCOs. Inspired by the success of large language models (LLMs), we examined the adaptability of three LLMs, GPT-2, BioGPT, and PMC-LLaMA, on PCO tasks across three institutions, Mayo Clinic, Emory University Hospital, and Stanford University. We developed an open-source framework for fine-tuning LLM that can directly extract the five different categories of PCO from the clinic notes. RESULTS We found that these LLMs without fine-tuning (zero-shot) struggle with challenging PCO extraction tasks, displaying almost random performance, even with some task-specific examples (few-shot learning). The performance of our fine-tuned, task-specific models is notably superior compared with their non–fine-tuned LLM models. Moreover, the fine-tuned GPT-2 model has demonstrated a significantly better performance than the other two larger LLMs. CONCLUSION Our discovery indicates that although LLMs serve as effective general-purpose models for tasks across various domains, they require fine-tuning when applied to the clinician domain. Our proposed approach has the potential to lead more efficient, adaptable models for PCO information extraction, reducing reliance on extensive computational resources while still delivering superior performance for specific tasks.

AbstractWith the proliferation of cancer research based on large databases, misalignment of research questions and data set capabilities is inevitable. Nationally maintained databases are appealing to cancer researchers because of the ease of access to large amounts of patient data available for analysis and risk estimation. Data sets that are commonly used in cancer research include the National Cancer Database, the SEER (Surveillance, Epidemiology, and End Results) program of the National Cancer Institute, the SEER–Medicare database, the American College of Surgeons National Surgical Quality Improvement Program, and the Healthcare Cost and Utilization Project databases, among others. Each data set has pros and cons with respect to variable availability and the ability to analyze cancer‐specific outcomes. It is critical for researchers to understand the strengths and limitations of each database. Changing variable definitions, the length of postoperative data collection, and the availability of patient‐reported outcomes or social determinants of health data are examples of factors that researchers must consider when selecting a data set for research purposes. For the current review, the authors summarized the advantages and disadvantages of various national data sets for cohort studies in cancer populations.

Neuroblastoma is the most common extracranial solid tumor diagnosed in children. This inaugural version of the NCCN Guidelines for Neuroblastoma provides recommendations for the diagnosis, risk classification, and treatment of neuroblastoma. The information in these guidelines was developed by the NCCN Neuroblastoma Panel, a multidisciplinary group of representatives with expertise in neuroblastoma, consisting of pediatric oncologists, radiologists, pathologists, surgeons, and radiation oncologists from NCCN Member Institutions. The evidence-based and consensus recommendations contained in the NCCN Guidelines are intended to guide clinicians in selecting the most appropriate treatments for their patients with this clinically heterogeneous disease.

AbstractPrior studies have suggested that immune thrombotic thrombocytopenic purpura (iTTP) may display seasonal variation; however, methodologic limitations and sample sizes have diminished the ability to perform a rigorous assessment. This 5‐year retrospective study assessed the epidemiology of iTTP and determined whether it displays a seasonal pattern. Patients with both initial and relapsed iTTP (defined as a disintegrin and metalloprotease with thrombospondin type motifs 13 activity <10%) from 24 tertiary centers in Australia, Canada, France, Greece, Italy, Spain, and the US were included. Seasons were defined as: Northern Hemisphere—winter (December–February); spring (March–May); summer (June–August); autumn (September–November) and Southern Hemisphere—winter (June–August); spring (September–November); summer (December–February); autumn (March–May). Additional outcomes included the mean temperature in months with and without an iTTP episode at each site. A total of 583 patients experienced 719 iTTP episodes. The observed proportion of iTTP episodes during the winter was significantly greater than expected if equally distributed across seasons (28.5%, 205/719, 25.3%–31.9%; p = .03). Distance from the equator and mean temperature deviation both positively correlated with the proportion of iTTP episodes during winter. Acute iTTP episodes were associated with the winter season and colder temperatures, with a second peak during summer. Occurrence during winter was most pronounced at sites further from the equator and/or with greater annual temperature deviations. Understanding the etiologies underlying seasonal patterns of disease may assist in discovery and development of future preventative therapies and inform models for resource utilization.

Introduction The treatment of cancer is associated with high risk for toxicity and high cost. Strategies to enhance the value, quality, and safety of cancer care are often managed independently of one another. Oncology stewardship is a potential framework to unify these efforts and enhance outcomes. This landscape survey establishes baseline information on oncology stewardship in the United States. Methods The Hematology/Oncology Pharmacy Association (HOPA) distributed a 38-item survey composed of demographic, institutional, clinical decision-making, support staff, metrics, and technology sections to 675 HOPA members between 9 September 2022 and 9 October 2022. Results Most organizations (78%) have adopted general pharmacy stewardship practices; however, only 31% reported having established a formalized oncology stewardship team. More than 70% of respondents reported implementation of biosimilars, formulary management, and dose rounding as oncology stewardship initiatives in both inpatient and outpatient settings. Frequently cited barriers to oncology stewardship included lack of clinical pharmacist availability (74%), lack of oncology stewardship training (62%), lack of physician/provider buy-in (32%), and lack of cost-saving metrics (33%). Only 6.6% of survey respondents reported their organization had defined “value in oncology.” Lack of a formalized stewardship program was most often cited (77%) as the rationale for not defining value. Conclusions Less than one-third of respondents have established oncology stewardship programs; however, most are providing oncology stewardship practices. This manuscript serves as a call to action for stakeholders to work together to formalize oncology stewardship programs that optimize value, quality, and safety for patients with cancer.

AbstractBackgroundTranscatheter tricuspid valve‐in‐valve (ViV) replacement has yielded good hemodynamic outcomes in the treatment of dysfunctional bioprosthetic valves (BPVs). Intentional fracture of certain rigid BPV frames, if feasible, allows a larger implanted valve when compared with implant into an unfractured BPV. There remains limited data on the feasibility of tricuspid valve frame fracture.AimsEvaluate the feasibility of transcatheter tricuspid ViV replacement with fracture of the underlying BPV ring.MethodsAn international multicenter registry of tricuspid ViV replacement with intentional tricuspid valve frame fracture was created. Demographic data along with procedural characteristics, outcomes, and follow‐up data were collected. Comparison was made to the pre‐ and post‐ViV replacement with fracture of the tricuspid valve frame conditions.ResultsTen patients from six centers were included with a median age and weight of 29 years and 67.3 kg respectively. Tricuspid valve frame fracture was performed using a median balloon diameter 3 mm (IQR 3–5) larger than the true inner diameter (ID). The final ID was a mean of 1.5 mm (95% CI: 0.35, 2.64: p < 0.05), and median 1.1 mm (0.5, 2.1) larger than the reported true ID of the surgical BPV after ViV replacement. The mean tricuspid inflow gradient by echocardiogram decreased by 6.65 mmHg (95% CI: 4.14, 9.15: p < 0.001). All procedures were without complication, specifically there was no heart block, pericardial effusion, or right coronary disruption.ConclusionIntentional tricuspid valve frame fracture with tricuspid ViV replacement is feasible and can increase the valve orifice potentially reducing the risk of ViV patient prosthesis mismatch and is not associated with significant complications.

ImportanceCutaneous squamous cell carcinoma (CSCC) is the second most common malignant disease in the US. Although it typically carries a good prognosis, a subset of CSCCs are highly aggressive, carrying regional and distant metastatic potential. Due to its high incidence, this aggressive subset is responsible for considerable mortality, with an overall annual mortality estimated to equal or even surpass melanoma. Despite this morbidity, CSCC is excluded from national cancer registries, making it difficult to study its epidemiology and outcomes. Therefore, the bulk of the CSCC literature is composed of single-center and multi-institutional retrospective cohort analyses. Given variations in reporting measures and analyses in these studies, interpretability between studies and the ability to pool results are limited.ObjectiveTo define standardized reporting measures for retrospective CSCC studies.FindingsAn expert panel was convened to determine standardized guidelines for recording and analyzing retrospective CSCC data. A total of 13 dermatologists and dermatologic surgeons with more than 5 years of posttraining experience and considerable experience with performing CSCC outcomes research were recruited to the panel. Consensus recommendations were achieved for CSCC retrospective study reporting measures, definitions, and analyses.Conclusions and RelevanceThe recommendations in this report present the potential to standardize future CSCC retrospective studies. With such standardization, future work may have greater interstudy interpretability and allow for pooled analyses.

The accumulation of senescent cells, a hallmark phenotype of aging tissues, elevates the risk of cardiovascular disease with age. Our prior studies have illustrated a crucial role played by senescent cells in promoting coagulation during murine atherosclerosis through the senescence-associated secretory phenotype (SASP). To explore the heterogeneity of senescent vascular cells in thrombotic vascular diseases and identify potential druggable pathways to counter senescence, we utilized the senescence reporter mouse p16TdTomato+/-, which was injected with an adeno-associated virus expressing Proprotein Convertase Subtilisin/Kexin type 9 to induce atherosclerosis when subjected to a high-fat diet (HFD). In a subset of HFD mice, some were left untreated, while others were treated with senolytic drug ABT-737 to selectively eliminate senescent cells. Aortas from ABT-737-treated mice exhibited increased collagen deposition and reduced arterial stiffness. Paired with pseudo-bulk RNA-sequencing analysis, we observed that HFD-induced extracellular matrix (ECM) remodeling genes were diminished by ABT-737, suggesting that ECM-platelet interactions may be influenced by senescence. Single-cell RNA-sequencing analysis from aortas identified 28 distinct cell clusters. Utilizing Gene Set Enrichment Analysis with the SenMayo and CellAge panels, we identified four cell clusters exhibiting increased senescent features that were mitigated by ABT-737. These included two VSMC clusters, fibroblasts, and neutrophil-like cells. Unbiased subclustering of potentially senescent clusters revealed a small population of cells enriched with HFD and reduced by ABT-737, confirming their senescent nature. In the most abundant cluster, Spp1 and Serpine2 strongly represented the senescent VSMC subpopulation, enriched for TGFβ signaling, ECM remodeling, and coagulation cascade genes. Further, we validated these findings through spatial transcriptomics and single-molecule FISH of brachiocephalic arteries from atherosclerotic mice and atherosclerotic mice depleted of senescent cells. Our results reveal a novel transcriptomic signature for senescent vascular cells that holds potential for therapeutic targeting in age-related vascular diseases.

Abstract Unirradiated patients with relapsed/refractory (R/R) B-cell non-Hodgkin lymphoma (NHL) who undergo anti-CD19 chimeric antigen receptor T-cell therapy (CART) have a predominant localized pattern of relapse, the significance of which is heightened in individuals with limited/localized disease before CART. This study reports on the outcomes of patients with R/R NHL and limited (&lt;5 involved sites) disease bridged with or without radiotherapy. A multicenter retrospective review of 150 patients with R/R NHL who received CART with &lt;5 disease sites before leukapheresis was performed. Bridging treatment, if any, was administered between leukapheresis and CART infusion. Study end points included relapse-free survival (RFS), event-free survival (EFS), and overall survival. Before CART infusion, 48 patients (32%) received bridging radiotherapy (BRT), and 102 (68%) did not. The median follow-up was 21 months. After CART infusion, BRT patients had higher objective response (92% vs 78%; P = .046) and sustained complete response rates (54% vs 33%; P = .015). Local relapse in sites present before CART was lower in the BRT group (21% vs 46%; P = .003). BRT patients had improved 2-year RFS (53% vs 44%; P = .023) and 2-year EFS (37% vs 34%; P = .039) compared with patients who did not receive BRT. The impact of BRT was most prominent in patients who had ≤2 pre-CART involved disease sites, with 2-year RFS of 62% in patients who received BRT compared with 42% in those who did not (P = .002). BRT before CART for patients with limited (&lt;5 involved disease sites) R/R NHL improves response rate, local control, RFS, and EFS without causing significant toxicities.
