PURPOSE Systematic integration of tobacco cessation treatment within cancer centers is needed to improve smoking cessation outcomes among cancer patients and survivors. The current study characterizes baseline rates of tobacco use, use of cessation support, and changes in tobacco use over time among 756 participants diagnosed with cancer and enrolled in 9 ECOG-ACRIN Cancer Research Group trials. MATERIALS AND METHODS Participants completed surveys at trial enrollment and at 3- and 6-month follow-ups. Descriptive statistics were used to characterize patient characteristics and selected items from the Cancer Patient Tobacco Use Questionnaire (C-TUQ). Generalized estimating equations were used to examine the time point effect on tobacco product use. RESULTS At baseline, 11% of participants (n = 740) currently smoked cigarettes. Among participants with data available at all time points (n = 443), prevalence of current smoking was stable over time, with 7.2% of participants (n = 32) reporting current smoking at baseline, 7.0% (n = 31) at the 3-month follow-up assessment, and 6.8% (n = 30) at the 6-month follow-up assessment. Most participants (n = 77/104) who smoked cigarettes within the year prior to their cancer diagnosis continued smoking after their diagnosis, and during (n = 44/72) and following completion (n = 30/46) of their treatment. Sixty-two percent of participants (n = 81) who were currently smoking at baseline reported using smoking cessation medication and 32.1% reported use of nonpharmacologic smoking cessation support since their cancer diagnosis. In longitudinal analyses, the odds of using cigarettes since their cancer diagnosis, 3-month follow-up, and 6-month follow-up was higher than the odds of using cigarettes for the past 30 days at baseline (odds ratio [OR] = 1.97, OR = 1.62, and OR = 1.50, respectively; all p s < .01). CONCLUSION Smoking persists over time among patients with cancer enrolled in therapeutic cancer trials. Findings highlight the importance of increasing access to integrated and longitudinal smoking cessation support.

Abstract Purpose This study evaluates associations with suicidal ideation (SI) of impact of work on personal relationships (IWPR), self-valuation (SV), and imposter phenomenon and compares the SI point prevalence in physicians vs other workers. Method This study used American Medical Association Physician Professional Data to sample US physicians across different specialties between November 2020-March 2021. Of 7360 survey respondents, 6497 (88.3%) completed the SI question. A probability-based sample included 2508 nonphysician individuals from the US population employed at the time of survey administration, with 2501 workers (99.7%) completing the SI item. Logistic regression was used to evaluate the associations of occupational distress factors, including IWPR, SV, imposter phenomenon, and other factors, with SI before and after adjusting for depression and compare the risk of SI among physicians with other US workers. Results The study included 6497 physicians and 2501 workers in other fields. Adjusting for sex, age, relationship status, parenting status, and depression, each 1-point higher IWPR score (range, 0-10) was associated with 10% increased SI odds (odds ratio [OR], 1.10; 95% confidence interval [CI], 1.05-1.15). Adjusting for the same variables, each 1-point higher SV score (range, 0-10) was associated with 10% lower SI odds (OR, 0.90; 95% CI, 0.85-0.95). The association between imposter phenomenon scores (range, 4-20) and SI was not statistically significant (OR, 1.03; 95% CI, 0.99-1.08). The unadjusted 1-year SI point prevalence was 6.6% (95% CI, 6.0%-7.4%) in physicians vs 5.6% (95% CI, 4.7%-6.6%) among workers in other fields (P = .09). In a multivariable model, workers in other fields with a bachelor’s or master’s degree had lower SI odds compared with physicians (OR, 0.64; 95% CI, 0.46-0.87). Conclusions IWPR and low SV are associated with SI among physicians, independent of depression. Development and evaluation of interventions designed to mitigate these factors in physicians may be warranted.

Background: While surgeon burnout is extensively documented, the medical community has limited corresponding data regarding what it might mean to thrive in the profession as captured by robust measures of “flourishing.” Study Design: We conducted a cross-sectional survey measuring flourishing in a sample of 1,000 practicing US surgeons from the American Medical Association Masterfile between September and December 2025, including the Harvard Flourish Index (FI) and Secure Flourish Index (SFI). We used multivariable regression to assess personal and professional correlates of flourishing. Results Of 959 eligible surgeons in our sample, 283 (30%) responded. Mean flourishing (SFI) score was 7.98 (± 1.21) on a 0-10 scale (higher score=higher flourishing). Surgeons reported the highest flourishing in "Financial and Material Stability" (8.57 ± 2.11) and "Meaning and Purpose" (8.50 ± 1.39), while "Close Social Relationships" (7.41 ± 2.08) was the lowest-ranked domain. In multivariate linear regression, working fewer hours (adjusted β (each additional hour), -0.02; p<0.001), having children (adjusted β, 0.43; p=0.05) and viewing surgery as a calling (adjusted β, 0.28; p=0.006) were associated with higher flourishing. A majority (88%) of surgeons view the profession as a calling. Conclusion: Practicing surgeons report high levels of flourishing, with scores surpassing several historical medical and non-medical cohorts. Most surgeons reported comparatively high scores in meaning and purpose concurrent with deficits in social connectivity. Burnout and well-being conversations in the surgical professions may benefit from a flourishing framework. Naming meaning and purpose exemplars while being able to identify key deficits like social connectivity may be crucial for helping surgeons thrive.

Abstract Purpose To evaluate the correlation between occupational burnout and depression, frequency with which they coexist, how often 1 condition may be present in the absence of the other, and their association with suicidal ideation. Method The authors conducted a secondary analysis of cross-sectional national surveys of practicing U.S. physicians (conducted October 19, 2023, to March 3, 2024) and residents/fellows (“trainees”; conducted November 30, 2023, to January 2, 2024). They measured correlation between emotional exhaustion (EE) and depersonalization (DP) scores using the Maslach Burnout Inventory and depression T-scores using the National Institutes of Health Patient Reported Outcomes Measurement Information System Depression scale. Results A total of 5993 practicing physicians and 2676 trainees were included in the analysis. The pooled R2 value between EE and depression scores for physicians and trainees was 0.42 (P &lt; .001) and between DP and depression scores was 0.28 (P &lt; .001). Among the 4087 practicing physicians with normal depression scores, 1201 (29.4%) had high EE and/or high DP. Among the 1601 trainees with normal depression scores, 485 (30.3%) had high EE and/or high DP. On multivariable logistic regression adjusting for age, gender, relationship status, and work hours, each 1-point increase in depression T-score was associated with 15% higher odds of suicidal ideation among practicing physicians (OR 1.15; 95% CI, 1.13–1.17; P &lt; .001) and trainees (OR 1.15, 95% CI, 1.13–1.17; P &lt; .001). No statistically significant association between EE or DP scores and suicidal ideation was observed. Conclusions Occupational burnout and depression are correlated but distinct constructs with distinct outcomes. Less than half the variation in burnout is explained by depression (and vice versa). Population health approaches to improve physician well-being should address both conditions. Organizational efforts should go beyond providing support for individuals experiencing distress and also address the work environment factors that contribute to it.

Abstract Prognostic indices such as the CLL International Prognostic Index (CLL-IPI) and the International Prognostic Score for Early-stage CLL (IPS-E) can predict time to first treatment (TTFT) in patients with early-stage CLL. Their ability to predict risk of infection - a leading contributor to morbidity and mortality in CLL - remains uncertain. The CLL-TIM is a machine-learning model developed in Europe that integrates clinical, laboratory, and infection-related data to predict TTFT or infection risk within 2-years of diagnosis, Receiver Operating Characteristic - Area Under the Curve (ROC-AUC) 0.74; Agius et al., Nat Comm 11, 363 2020. We conducted the first validation of CLL-TIM in a US cohort of newly diagnosed CLL patients and compared its performance with the CLL-IPI and IPS-E indices. Adults with newly diagnosed CLL (2000-2020) were identified through the Rochester Epidemiology Project using International Classification of Disease (ICD) codes; all diagnoses were confirmed. We replicated the variable selection from the original CLL-TIM model and applied it to our cohort. The primary endpoint was a 2-year composite of either TTFT or incident infection (defined as having blood cultures drawn). Model performance was evaluated using ROC-AUC consistent with the original CLL-TIM methods. CLL-IPI and IPS-E performance was assessed using time-dependent ROC-AUC; pairwise differences in discrimination were tested using DeLong. We identified 454 CLL patients with a median age of 72 years [range, 30-97], 166 (37%) were female, Rai Stage was 0-II in 399 (92%) patients. IGHV genes were unmutated in 130/305 (42%) patients and TP53 disruption (either del17p by FISH or TP53 mutation) was present in 24/329 (8%) patients. At 2-years, 55 (12%) patients received CLL therapy, and 56 (12%) patients had an infection. The 2-year composite endpoint was observed in 94 (21%) patients. The ROC-AUC was 0.74 (95% CI 0.68-0.80) for CLL-TIM, 0.69 for CLL-IPI (95% CI 0.63-0.75, p=0.11 compared to CLL-TIM) , and 0.68 for IPS-E (95% CI 0.62-0.74, p=0.02 compared to CLL-TIM). We also evaluated the ROC-AUC using all the prognostic models for each individual endpoints. The corresponding ROC-AUC for TTFT at 2 years were 0.79, 0.74, and 0.76 for CLL-TIM, CLL-IPI, and IPS-E, respectively; and for infection at 2 years were 0.68, 0.57, and 0.52, respectively. This is the first validation of the CLL-TIM in a US-based cohort of newly diagnosed CLL patients. Although the CLL-TIM model exceeded the minimally meaningful discrimination threshold (AUC &gt;0.7) for individual patient-level risk prediction, there was no statistical difference in AUC between CLL-TIM and CLL-IPI, suggesting either model can predict the composite endpoint at 2 years. Most of the observed discrimination was driven by prediction of TTFT rather than infection, underscoring the need to develop more infection-specific risk models for newly diagnosed CLL.

Importance Exploring the relationship between moral distress and occupational burnout is necessary to understand the association between these constructs. Objective To evaluate moral distress among physicians and US workers, and to explore the association of moral distress with burnout, intent to leave (ITL) current position, and intent to reduce clinical work hours (ITR). Design, Setting, and Participants This cross-sectional national survey study included physicians from all specialties and a probability-based sample of employed nonphysicians. Participants were aged 29 to 65 years. Data were collected between October 19, 2023, and March 5, 2024. Data were analyzed from June 30 to October 20, 2025. Main Outcomes and Measures Moral distress was measured using the Moral Distress Thermometer (MDT, range 0-10), with a high level of moral distress defined by a score of 4 or higher. Burnout was measured using the complete Maslach Burnout Inventory (MBI). Professional fulfillment was measured using the Stanford Professional Fulfillment Index. ITL and ITR were measured using a standardized item with response options of none, slight, moderate, likely, and definitely. Results This survey study included 5741 physicians and 3501 nonphysician US workers. The median (IQR) age of physicians was 53 (44-62), and included 3262 men (58.0%), 2255 women (40.1%), and 107 individuals who responded other (1.9%). The mean (SD) moral distress score for physicians was 3.29 (2.81), with 2243 (39.1%) reporting a high level of moral distress (4 or more considered high). On multivariable analysis, women physicians had higher odds of moral distress (OR, 1.29; 95% CI, 1.12-1.48). Compared with internal medicine subspecialists, emergency medicine physicians (OR, 3.16; 95% CI, 2.27-4.4) and general internal medicine physicians (OR, 1.92; 95% CI, 1.42-2.59) were more likely to report high levels of moral distress. Mean emotional exhaustion and depersonalization scores, as well as the proportion of physicians with burnout, were higher with each 1-point increase in moral distress score. The overall correlation between the emotional exhaustion score and moral distress score was R = 0.55 ( P &amp;lt; .001) while the correlation between the depersonalization score and moral distress score was R = 0.50 ( P &amp;lt; .001). Additionally, 1068 of 3477 physicians (30.7%) with a moral distress score less than 4 had burnout symptoms compared with 1675 of 2231 physicians (75.1%) with scores of 4 or more ( P &amp;lt; .001). The prevalence of ITL and ITR was higher for each 1-point increase in moral distress score. For example, 619 of 3404 physicians (18.2%) with low moral distress reported ITL within 24 months compared with 748 of 2171 (34.5%) among those with high moral distress ( P &amp;lt; .001). Compared with other US workers, physicians had markedly higher odds of experiencing moral distress (OR, 4.40; 95% CI, 3.84-5.06). Conclusion and Relevance In this survey study, moral distress was common among physicians and experienced at higher rates than the general US working population. Understanding the differences between moral distress and burnout may allow organizations to more effectively implement interventions to address both concerns among clinicians.

Abstract Creating a People-Centered Organization: 12 Organizational Actions to Reduce Burnout and Foster Professional Fulfillment tells the story of the evolving journey to create a better work environment for health care professionals. It dwells not on the story of occupational distress, burnout, moral injury, and cognitive dissonance but rather on a narrative of hope, well-being, camaraderie, values alignment, and meaning. Achieving this aspiration requires health care professionals and operational leaders working together to create 10 “Ideal Work Elements”: community at work and camaraderie; intrinsic motivation and rewards; control and flexibility; fairness and equity; professional development and mentorship; partnership; safety; trust and respect; gratitude; and work–life Integration. The ultimate aspiration is a people-centered organization with a culture that inspires enthusiasm, loyalty, engagement, and strong regard for the welfare of the team and the best interests of patients. Creating a People-Centered Organization: 12 Organizational Actions to Reduce Burnout and Foster Professional Fulfillment provides a road map for you to create such an environment for your team and organization. The map is paved with information about reliable, thoughtfully designed systems built on a psychologically safe and just culture. The authors drew on their extensive research on the well-being of health care professionals and their executive leadership experience in staff wellness, quality improvement, organization development, and operations management.

Bruton tyrosine kinase inhibitors (BTKis) and BCL2 inhibitor (BCL2i)–containing regimens significantly improve survival outcomes in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Results from randomized clinical trials have demonstrated that time-limited treatment with BCL2i-containing regimens resulted in higher rates of undetectable measurable residual disease (uMRD) than BTKi monotherapy or chemoimmunotherapy (CIT). Pirtobrutinib (a noncovalent BTKi) and lisocabtagene maraleucel (CD19-directed CAR T-cell therapy) are newer options for relapsed or refractory disease after prior therapy with BTKi and BCL2i-contining regimens. Histologic transformation of CLL/SLL to diffuse large B-cell lymphoma (Richter transformation) is associated with a poor prognosis. Molecular analysis to determine whether there is clonal relationship between CLL/SLL and transformed diffuse large B-cell lymphoma is useful to select an appropriate treatment option. These NCCN Guideline Insights highlight significant updates to the NCCN Guidelines for the treatment of CLL/SLL and Richter transformation.

Abstract Background: Monoclonal B-cell lymphocytosis (MBL), a precursor to chronic lymphocytic leukemia (CLL), is an understudied yet common premalignant condition present in ~8 million adults in the United States. Based on flow cytometry, MBL can be classified into two immunophenotypes: CLL-type (CD5, CD23, and CD20 co-expression) and non-CLL-type (CD5-negative). While the majority of the data to date pertains to CLL-type MBL, the available evidence indicates non-CLL-type MBL is also associated with an increased risk of hematologic malignancies. Clonal hematopoiesis of indeterminate potential (CHIP) is another precursor condition associated with hematologic malignancies. The relationship between non-CLL-type MBL and CHIP and their combined effect remains unknown. Herein, we report findings on these two precursor conditions in the largest screening cohort to date. Methods: Using flow cytometry, we screened for MBL in the Mayo Clinic Biobank participants who were 40 years or older with no prior history of hematologic cancers. Using whole-exome sequencing of whole-blood DNA, CHIP was screened on 291 genes related to myeloid (56 genes) or lymphoid malignancies (235 genes). Incident hematologic malignancies were detected during follow-up using International Classification of Diseases (ICD) codes in the medical record. All diagnoses were manually reviewed for confirmation. Multivariable logistic regression was used to evaluate the association between non-CLL-type MBL and CHIP. Time to incident hematologic malignancy was calculated from date of MBL screening to the earliest date of incident malignancy, withdrawal, death, last medical visit, or study end. Overall survival (OS) was calculated from date of MBL screening to date of death or last known alive. Multivariable Cox regression, adjusted for age, sex and residency, was used to investigate associations between non-CLL-type MBL and CHIP with clinical outcomes; with results reported using hazard ratios (HR) and 95% confidence intervals (CI). Results: In total, 8,802 individuals with MBL screening and CHIP data were analyzed. Non-CLL-type MBL was detected in 249 (2.8%) individuals; 121 (49%) were male, and median age was 78 years (range, 47-95). We identified 757 (8.6%) individuals with CHIP in at least one of the 291 genes tested. The most frequently mutated CHIP genes were DNMT3A, TET2, ASXL1, PPM1D, and TP53. A total of 47 (0.5%) individuals had both non-CLL-type MBL and CHIP; the four genes with the highest number of CHIP variants in these individuals were DNMT3A (n=16), TET2 (n=10), ASXL1 (n=3), and ATM (n=3). An association between non-CLL-type MBL and any CHIP (OR=1.6, 95%CI:1.2-2.3, P=0.006) was observed. When analyzing CHIP in genes related to myeloid malignancies, the association with non-CLL-type MBL was also significant (OR=1.6, 95%CI:1.1-2.3, P=0.012); however, the association was not statistically significant for genes related to lymphoid malignancies (OR=1.6, 95%CI:0.8-3.3, P=0.165). With a median follow-up of 5.4 years, 104 individuals developed incident hematologic malignancies (66 lymphoid and 38 myeloid malignancies). Non-CLL-type MBL (HR=3.5, 95%CI:1.9-6.5, P&lt;0.001) and CHIP (HR=3.2, 95%CI:2.1-5.1, P&lt;0.001) were each associated with increased risk of incident hematologic malignancies. Co-existence of both precursor conditions was associated with a substantially higher risk of incident hematologic malignancies (HR=10.3, 95%CI:4.0-26.2, P&lt;0.001) compared to individuals with neither precursor condition. Among individuals with non-CLL-like MBL, any CHIP was a borderline significant predictor for incident hematologic malignancy (HR=3.6, 95%CI:1.0-12.9, P=0.049). Compared to individuals with no precursor conditions, OS was not significantly different in those with non-CLL-type MBL-only (HR=1.1, 95%CI:0.8-1.5, P=0.40), those with CHIP-only (HR=1.2, 95%CI:0.99-1.4, P=0.06), or those with both CHIP and non-CLL-type MBL (HR=1.3, 95%CI:0.8-2.1, P=0.39). Conclusions: In the largest screening cohort to date evaluating the relationship of CHIP and non-CLL-type MBL, we found that non-CLL-type MBL and CHIP are associated with each other. Individuals with non-CLL-type MBL were more likely to have CHIP variants in DNMT3A, TET2, ASXL1, and ATM. Among individuals with non-CLL-type MBL, the presence of any CHIP was associated with increased risk of developing hematologic malignancy.

Abstract Introduction: Chronic lymphocytic leukemia (CLL) is marked by impaired T cell responses that limit the efficacy of immunotherapies. CD19-directed chimeric antigen receptor T cell therapy (CART19) received FDA approval to treat CLL in 2024. However, itsefficacy in CLL patients remains low, with durable remission rate of ~20%. Ibrutinib, a Bruton tyrosine kinase inhibitor, has shown synergy with CART19 in preclinical and early clinical studies. We aimed to study the impact of ibrutinib on CART19 utilizing clinical samples from the pivotal clinical trial E1912 (NCT02048813) of ibrutinib/rituximab (IR) vs fludarabine/cyclophosphamide/rituximab (FCR). This trial led to the FDA approval of first line ibrutinib in CLL. Methods: We generated CART19 incorporating either CD28 (28ζ) or 41BB (BBζ) costimulatory domains from T cells isolated from patients with CLL treated with IR or FCR on the E1912 trial. IR samples were collected at baseline (pretreatment), 6- or 12-months during treatment, or at progression. FCR samples were collected at baseline, 15-18 months during treatment, or at progression. For animal experiments, NOD-SCID-γ-/- (NSG) mice were intravenously (i.v.) engrafted with 1×10⁶ luciferase⁺ CD19⁺ JeKo-1 cells. Upon tumor establishment (~10⁸ photons/sec by bioluminescence imaging), mice were randomized and treated i.v. with 1×10⁶ 28ζ or BBζ derived from longitudinal IR- or FCR-treated patient samples. To further assess the impact of prolonged ibrutinib exposure on CART19 function, we chronically stimulated healthy donor-derived 28ζ or BBζ in vitro for 22 days with JeKo-1 cells and 100nM ibrutinib or vehicle control and then tested CART19 functions. Finally, we performed single cell RNA sequencing (scRNAseq) of longitudinal patient T cell samples treated with IR. Results: Ex vivo T cell expansion was significantly enhanced following IR compared to FCR. BBζ generated from IR-treated patients after 6 months of ibrutinib exhibited enhanced in vitro expansion (p=0.016) and antigen-specific proliferation (p=0.038) in the presence of JeKo-1 cells. This corresponded with significantly improved antitumor efficacy and prolonged survival in vivo compared to cells generated at disease progression (p=0.017). In contrast, 28ζ showed no significant differences in efficacy across IR studied treatment timepoints. BBζ from FCR-treated patients did not show differences in tumor control based on treatment timepoints but demonstrated shorter survival compared to BBζ from IR-treated patients. 28ζ from FCR-treated patients generated at disease progression demonstrated significantly reduced tumor control and shorter survival compared to 28ζ produced at baseline (p=0.0002), indicating detrimental effects of FCR treatment on the therapeutic potential of CART products. To further investigate the impact of prolonged ibrutinib exposure, we utilized in vitro models of CART exhaustion. We found that, after repeated antigen stimulation with JeKo-1 cells, ibrutinib-treated BBζ had significantly increased antigen-specific degranulation (p=0.005), and cytokine production (IL-2, p=0.045; TNF-α, p=0.003; IFN-γ, p=0.001), compared to BBζ treated with vehicle control. In contrast, 28ζ did not show improved degranulation or cytokine production in cocultures with ibrutinib. Prolonged ibrutinib exposure led to downregulation of FOXO3, a transcription factor associated with T cell exhaustion which has been shown to cause dysfunction specifically in BBζ. These results further indicate that ibrutinib may be more beneficial to BBζ. Indeed, scRNAseq revealed that after ≥ 6 months of ibrutinib, T cells showed downregulation of inflammatory, oxidative stress, and apoptosis pathways, paralleled by modest activation of MYC and E2F targets. However, at disease progression, T cells under ibrutinib treatment displayed marked upregulation of interferon signaling, inflammation responses, and stress-related programs, indicating a shift toward immune reactivation or dysfunction.Conclusion: Our study shows that BBζ, but not 28ζ, generated 6 months during ibrutinib treatment has superior antitumor activity and persistence compared to similar later timepoints or FCR-treated counterparts. Prolonged ibrutinib exposure enhances BBζ function by modulating stress and apoptotic pathways. These findings highlight the importance of pre-CART treatment timing and support ibrutinib as a potential enhancer of CART cell fitness in CLL.
