e13121 Background: Triple-negative breast cancer (TNBC) lacks reliable prognostic biomarkers beyond standard clinical staging, limiting individualized risk stratification and treatment planning. The neutrophil-to-lymphocyte ratio (NLR), a readily available marker of systemic inflammation, has been proposed as a prognostic indicator in TNBC; however, existing evidence remains inconsistent. We performed an updated systematic review and meta-analysis to evaluate the prognostic value of pretreatment NLR in the contemporary treatment era. Methods: PubMed, Embase, Cochrane CENTRAL, and ClinicalTrials.gov were systematically searched from database inception through January 1, 2026, for randomized and observational studies reporting associations between pretreatment NLR and survival outcomes in TNBC. Two reviewers independently screened studies and extracted data with discrepancies resolved by consensus. Outcomes included overall survival (OS), disease-free survival (DFS), and progression-free survival (PFS). Hazard ratios (HRs) were pooled using random-effects models. Risk of bias was assessed using ROBINS-I tool. Prespecified subgroup and sensitivity analyses were performed based on NLR cut-off values, follow-up duration, geographic region, and risk of bias. Results: Twenty-three retrospective studies comprising 4,731 patients with TNBC were included. On multivariate analysis, elevated pretreatment NLR was independently associated with poorer OS (HR 2.21, 95% CI: 1.56–3.13) and DFS (HR 1.97, 95% CI: 1.65–2.37. Similar associations were observed on univariate analysis (OS: HR 1.70, 95% CI: 1.07–2.72; DFS: HR 1.84, 95% CI: 1.14–2.98). No statistically significant or consistent association was observed between NLR and PFS. Associations between high NLR and adverse OS and DFS remained robust across prespecified subgroup and sensitivity analyses, representing the largest contemporary synthesis of multivariable-adjusted outcomes in TNBC. Key pooled outcome associations are summarized in Table 1. Conclusions: Elevated pretreatment NLR is independently associated with worse OS and DFS in patients with TNBC, supporting its potential role as a low-cost tool for clinical risk stratification and treatment planning. Given its availability from routine blood tests, NLR may assist in identifying high-risk patients who could benefit from intensified surveillance or therapeutic strategies. Prospective validation in the modern chemo-immunotherapy era is warranted. Summary of pooled associations between pretreatment NLR and survival outcomes in TNBC.

9022 Background: High quality education is crucial for hematology/oncology (H/O) training and lifelong learning. However, H/O has historically prioritized clinical and research careers over medical education careers. Consequently, few programs support H/O educators. A CoP is a group that shares “a concern or passion for something they do and learn how to do it better as they interact regularly.” We formed the ASCO Med Ed CoP in 2021 to provide a collaborative network and professional development venue for H/O educators. Methods: Following a published framework for developing a global health professions educator community (Establish-Grow-Sustain), we (ASCO Education Scholars Program graduates) developed CoP mission and vision statements and a leadership structure (Establish), formed committees and projects (Grow), and gathered at the ASCO Annual Meeting and via virtual Town Halls (Sustain). In 2023, we collected demographics and evaluated the CoP using a logic model focused on inputs, activities, outputs, and impact. Results: As of December 2023, the CoP includes 238 members from 143 institutions (38 [27%] non-U.S.): 207 (87%) ASCO members; 127 (53%) women, 106 (45%) men, 5 (2%) no response (NR); 111 (47%) White, 88 (37%) Asian/Pacific Islander, 27 (11%) Latinx/Hispanic, 12 (5%) Black/African-American, 8 (3%) Middle Eastern, 1 (0.4%) African, 16 (7%) NR; 146 (61%) hematologist/oncologists, 68 (29%) trainees, 6 (3%) radiation oncologists, 3 (1%) surgical oncologists, and 15 (6%) other professionals. The logic model is displayed (Table). Conclusions: The CoP has had an impact on its members, ASCO, and beyond and continues to grow and sustain itself by recruiting broadly, driving projects forward, and making structural adjustments for long-term sustainability. Upcoming projects include providing more educational resources and measuring outcomes such as changes in members’ knowledge, skills, and attitudes. Membership diversity continues to be a challenge and a priority. [Table: see text]

Purpose To develop a predictive machine learning model to identify prognostic factors for continued opioid prescriptions after arthroscopic meniscus surgery. Methods Patients undergoing arthroscopic meniscal surgery, such as meniscus debridement, repair, or revision at a single institution from 2013 to 2017 were retrospectively followed up to 1 year postoperatively. Procedural details were recorded, including concomitant procedures, primary versus revision, and whether a partial debridement or a repair was performed. Intraoperative arthritis severity was measured using the Outerbridge Classification. The number of opioid prescriptions in each month was recorded. Primary analysis used was the multivariate Cox‐Regression model. We then created a naïve Bayesian model, a machine learning classifier that uses Bayes’ theorem with an assumption of independence between variables. Results A total of 581 patients were reviewed. Postoperative opioid refills occurred in 98 patients (16.9%). Multivariate logistic modeling was used; independent risk factors for opioid refills included male sex, larger body mass index, and chronic preoperative opioid use, while meniscus resection demonstrated decreased likelihood of refills. Concomitant procedures, revision procedures, and presence of arthritis graded by the Outerbridge classification were not significant predictors of postoperative opioid refills. The naïve Bayesian model for extended postoperative opioid use demonstrated good fit with our cohort with an area under the curve of 0.79, sensitivity of 94.5%, positive predictive value (PPV) of 83%, and a detection rate of 78.2%. The two most important features in the model were preoperative opioid use and male sex. Conclusion After arthroscopic meniscus surgery, preoperative opioid consumption and male sex were the most significant predictors for sustained opioid use beyond 1 month postoperatively. Intraoperative arthritis was not an independent risk factor for continued refills. A machine learning algorithm performed with high accuracy, although with a high false positive rate, to function as a screening tool to identify patients filling additional narcotic prescriptions after surgery. Level of Evidence III, retrospective comparative study.

The use of social media continues to increase in health care and academia. Health care practice, particularly the oncologic field, is constantly changing because of new knowledge, evidence-based research, clinical trials, and government policies. Therefore, oncology trainees and professionals continue to strive to stay up-to-date with practice guidelines, research, and skills. Although social media as an educational and professional development tool is no longer completely new to medicine and has been embraced, it is still under-researched in terms of various outcomes. Social media plays several key roles in professional development and academic advancement. We reviewed the literature to evaluate how social media can be used for professional development and academic promotion of oncology professionals.

PURPOSE: The COVID-19 pandemic led to unprecedented challenges in medical training, and we sought to assess the specific impact of COVID-19 on hematology-oncology (HO) fellowship programs. METHODS: We conducted a cross-sectional anonymous online survey of 103 HO program directors (PDs) in conjunction with the American Society of Hematology (ASH) and ASCO. We sought to assess the specific impact of COVID-19 on HO fellowship programs' clinical, educational, and research activities, evaluate perceptions regarding PD and trainee emotional and mental health, and identify ways to support programs. Data were analyzed using descriptive statistics, parametric and nonparametric tests, and multivariable logistic regression models. Responses to open-ended questions were analyzed with thematic analysis. RESULTS: Significant changes to fellowship activities included transitioning fellow training from outpatient clinics to telehealth (77.7%), shifting to virtual education (94.2%), and moving to remote research work (63.1%). A minority (21.4%) of PDs reported that their fellows were redeployed to cover non-HO services. Most PDs (54.4%) believed COVID-19 had a slight negative impact on fellowship training. PD self-reported burnout increased significantly from 15.5% prepandemic to 44.7% during the pandemic, and most PDs witnessed minor signs of fellow burnout (52.4%). Common PD concerns included inadequate supervision for telehealth activities, reduced opportunities for fellow advancement and promotion, lack of professional development activities, limited research operations and funding, program financial constraints, and virtual recruitment. CONCLUSION: We encourage institutions and national societies to allocate resources and develop programs that can support fellowships and mitigate the potential negative effects of COVID-19 on trainee and PD career development.

PURPOSE: Graduate medical and research training has drastically changed during the COVID-19 pandemic, with widespread implementation of virtual learning, redeployment from core rotations to the care of patients with COVID-19, and significant emotional and physical stressors. The specific experience of hematology-oncology (HO) fellows during the COVID-19 pandemic is not known. METHODS: We conducted a mixed-methods study using a survey of Likert-style and open-ended questions to assess the training experience and well-being of HO fellows, including both clinical and postdoctoral trainee members of the American Society of Hematology and ASCO. RESULTS: A total of 2,306 surveys were distributed by e-mail; 548 (23.8%) fellows completed the survey. Nearly 40% of fellows felt that they had not received adequate mental health support during the pandemic, and 22% reported new symptoms of burnout. Pre-existing burnout before the pandemic, COVID-19–related clinical work, and working in a primary research or nonclinical setting were associated with increased burnout on multivariable logistic regression. Qualitative thematic analysis of open-ended responses revealed significant concerns about employment after training completion, perceived variable quality of virtual education and board preparation, loss of clinical opportunities to prepare for independent clinical practice, inadequate grant funding opportunities in part because of shifting research priorities, variable productivity, and mental health or stress during the pandemic. CONCLUSION: HO fellows have been profoundly affected by the pandemic, and our data illustrate multiple avenues for fellowship programs and national organizations to support both clinical and postdoctoral trainees.

Introduction The COVID-19 pandemic has significantly affected many aspects of healthcare, including medical education and training. Its impact on hematology/oncology (HO) fellowship programs has not yet been characterized. Methods The American Society of Hematology (ASH) and American Society of Clinical Oncology (ASCO) sent an anonymous survey in June 2020 to all HO program directors (PDs) addressing program changes during the COVID-19 pandemic and their perception of impact on trainees' experience, education, and mental health. The survey included 32 multiple-choice and open-ended questions. Participants who completed the survey received a $10 gift card. Quantitative descriptive analyses of multiple-choice questions were conducted. Open-ended responses were analyzed qualitatively using NVivo software. Results Of 233 invited PDs, 103 (44%) respondents completed the survey; 22 additional surveys were incomplete and not included in the analysis. Table 1 summarizes PDs and program characteristics. In response to the pandemic, 42% (N=43) of programs removed fellows from outpatient clinics and 63% (N=65) changed research location to home (Figure 1). Most PDs reported their fellows were participating in telehealth for HO care (79%, N=81) and 21% (N=22) had their fellows re-deployed to cover medicine and other non-HO services. To support fellows' mental health most programs held additional virtual meetings (76%, N=78) and social events (52%, N=54). Twenty one percent of PDs (N=22) reported their program's professional development funds were completely cut or frozen and 17% (N=17) had funds cut slightly. Most PDs reported the pandemic negatively impacted fellowship overall (67% slight to significant negative impact, N=69), 72% identified clinical education as negatively impacted (72% slight to significant negative impact, N=74), and 35% (N=36) reported significant negative impact on research training/productivity. Twenty three percent (N=24) of PDs thought their fellows were not able to make good use of their time during the pandemic, professionally speaking. One third (33%, N=34) of PDs anticipated the pandemic would lead to lack of fellow clinical preparedness, 24% (N=25) with need to make up clinical rotations, and 15% (N=15) anticipated a negative impact on HO board pass rates. Post-pandemic, most PDs plan to maintain some virtual educational sessions (73%, N=75) and telehealth in fellows' continuity clinic (55%, N=57). Among PDs, the prevalence of burnout increased from 16% (N=16) pre-pandemic to 45% (N=46) during the pandemic (p<0.0001). Seventeen percent (N=18) of PDs witnessed moderate signs of fellow burnout and 52% (N=54) witnessed minor signs of fellow burnout during the pandemic. Several educational and research constraints were identified via qualitative analysis: limited in-person clinical rotations, supervision of telehealth encounters, training year promotion and making up clinical time, limited professional development activities, board exam cancellations, and inability to perform research. Additional PD-identified trainee concerns included: ability to obtain childcare, separation from family, and Visa concerns among international fellows. PDs anticipated that financial constraints leading to cuts or removal of discretionary funds may have negative consequences for fellows' professional development activities and could force PDs to decrease program size in the future. PD recommendations for ASH and ASCO included: reducing or eliminating fellow membership fees, providing free access to educational materials and meetings, eliminating in-training examination fees, providing virtual sessions on career development, telehealth and wellness, virtual journal clubs, PD webinars focused on navigating fellowship issues and virtual interviews, and extending ASCO YIA funding for a second year. Conclusions PDs reported that their fellowship programs' clinical, educational, and research experiences have been impacted by the COVID-19 pandemic. PDs are concerned about the impact of budget cuts on fellows' professional and career development. PD burnout increased during the pandemic and most PDs observed at least mild burnout among their fellows. Professional societies can support fellowship programs by limiting fees and costs associated with membership, exams, and meetings, and increasing virtual opportunities for both fellows and PDs.

Introduction: While the COVID-19 pandemic has affected many aspects of clinical care, research, and medical training, its impact on hematology-oncology trainees and professional development has not been described. The American Society of Hematology (ASH) and the American Society of Clinical Oncology (ASCO) sought to assess the impact of COVID-19 on fellows enrolled in hematology-oncology programs. Methods: In spring 2020, ASH and ASCO developed and administered a survey by e-mail to active hematology-oncology fellow members. Response formats used both a semi-Likert scale and open-ended text. Questions focused on fellow experiences and how changes in their programs have impacted their personal and professional lives across several domains. Multiple-choice responses were analyzed using descriptive statistics, and NVivo software was used for qualitative analysis of open-ended questions. Results: Respondent demographics are described in Table 1. Of 2,306 trainees, 620 (27%) responded to the survey. Most respondents continued patient care responsibilities during the pandemic (80%). Almost half of all trainees (47%) reported that they felt less productive than usual. Stress and/or anxiety about the current situation was the most cited factor affecting productivity in the overall cohort (Figure 1). One-third (33%) of respondents had volunteered or were assigned to clinical/non-clinical COVID-19-related efforts. Of the 90 visa holders in our cohort, 30% (N=27) reported experiencing issues with their visa/immigration status. Eight percent of respondents stated their career plans had changed due to COVID-19. Of those who said their plans had changed, 30 respondents were considering careers in academia pre-pandemic and 11 were considering private practice. However, only 14 respondents were considering academia post-pandemic while 19 were interested in private practice. Overall, most respondents had concerns about at least one of the following: salary reductions, availability of networking events, family well-being, mental health and obtaining a job (Figure 2). The prevalence of burnout increased from 22% (N=105) before the pandemic to 33% (N=161) during (p<.001). Of the respondents who did not report burnout before COVID-19, 22% noted new-onset burnout during the pandemic. New-onset burnout prevalence varied based on the type of work respondents performed: no COVID-related work (17%), COVID-related non-clinical work (26%), and COVID-related clinical work (34%) (p<0.01). The open-ended responses yielded several consistent themes. Clinical and educational constraints were enumerated: lost learning opportunities due to low patient volumes, unavailability of colleagues to discuss cases, and overall low perceived quality of virtual learning. Trainees also reported reduced motivation to complete work within a stipulated time frame due to lack of robust discussions in the virtual environment and technological challenges in navigating educational resources. Trainee research was also severely impacted as laboratories closed, experimental animal colonies were lost, and many research activities ceased. Respondents also expressed concern that cuts in research training initiatives and budgets would jeopardize faculty positions for graduating fellows and that funding for travel and conferences was suspended. Fellows' recommendations for ASH and ASCO included improved online education, virtual research training and networking opportunities, practical guidance on caring for immune-compromised patients during the pandemic, increased funding resources for trainees, mental health resources, and advocating on behalf of trainee visa holders. Conclusions: Hematology-oncology trainees reported their training experiences have been deeply impacted by the COVID-19 pandemic. A majority of trainees are concerned about the negative impact on career opportunities, research funding, financial well-being, and mental health. Burnout increased during COVID-19, especially in trainees who were assigned to specific COVID-related efforts. Training programs and professional societies can support trainees by increasing trainee research funding, online networking and learning opportunities, mental health resources and, support for international trainees.
