Abstract The field of infectious diseases (ID) offers a rewarding career path and is widely viewed as an essential subspecialty in medicine. However, in recent years, these positive aspects have been overshadowed by concerns surrounding low fellowship match rates, undercompensation, and burnout. The Infectious Diseases Society of America Fellowship Training Program Directors Committee met in 2023, discussed the future of ID as a specialty, and sought to develop strategies to highlight the value and opportunities of ID for future generations, as well as underscore the importance of and provide tools for positive messaging to trainees about the subspecialty. This paper presents ideas generated at this meeting and is meant to serve as a reference for ID training program directors, as well as the wider ID community, in uplifting and shaping the future of the field.

PURPOSE The nodal burden of patients with residual isolated tumor cells (ITCs) in the sentinel lymph nodes (SLNs) after neoadjuvant chemotherapy (NAC) (ypN0i+) is unknown, and axillary management is not standardized. We investigated rates of additional positive lymph nodes (LNs) at axillary lymph node dissection (ALND) and oncologic outcomes in patients with ypN0i+ treated with and without ALND. METHODS The Oncoplastic Breast Consortium-05/ICARO cohort study (ClinicalTrials.gov identifier: NCT06464341 ) retrospectively analyzed data from patients with stage I to III breast cancer with ITCs in SLNs after NAC from 62 centers in 18 countries. The primary end point was the 3-year rate of any axillary recurrence. The rate of any invasive recurrence was the secondary end point. RESULTS In total, 583 patients were included, of whom 182 (31%) had completion ALND and 401 (69%) did not. The median age was 48 years. Most patients (74%) were clinically node-positive at diagnosis and 41% had hormone receptor–positive/human epidermal growth factor receptor 2–negative tumors. The mean number of SLNs with ITCs was 1.2. Patients treated with ALND were more likely to present with cN2/3 disease (17% v 7%, P < .001), have ITCs detected on frozen section (62% v 8%, P < .001), have lymphovascular invasion (38% v 24%, P < .001), and receive adjuvant chest wall (89% v 78%, P = .024) and nodal radiation (82% v 75%, P = .038). Additional positive nodes were found at ALND in 30% of patients, but only 5% had macrometastases. The 3-year rates of any axillary and any invasive recurrence were 2% (95% CI, 0.95 to 3.6) and 11% (95% CI, 8 to 14), respectively, with no statistical difference by type of axillary surgery. CONCLUSION The nodal burden in patients with ypN0(i+) was low, and axillary recurrence after ALND omission was rare in patients selected for this approach. These results do not support routine ALND in all patients with ypN0(i+).

Abstract With the increasing opportunities for medical management of von Hippel–Lindau (VHL)-related lesions, fundamental questions are arising regarding the possibilities of the FDA-approved medication (Belzutifan) to delay the progression of other non-VHL-related tumors that are not requiring urgent surgical interventions. We present a follow-up report on a VHL patient, with a co-morbid history of pulmonary mucosa-associated lymphoid tissue lymphoma, who was initially described in the clinical scientific literature ~10 years ago. This patient’s case highlights some of the challenges for some VHL patients with comorbid non-VHL-related tumors and potential opportunities for targeted support.

Abstract The OmicsFootPrint framework addresses the need for advanced multi-omics data analysis methodologies by transforming data into intuitive two-dimensional circular images and facilitating the interpretation of complex diseases. Utilizing deep neural networks and incorporating the SHapley Additive exPlanations algorithm, the framework enhances model interpretability. Tested with The Cancer Genome Atlas data, OmicsFootPrint effectively classified lung and breast cancer subtypes, achieving high area under the curve (AUC) scores—0.98 ± 0.02 for lung cancer subtype differentiation and 0.83 ± 0.07 for breast cancer PAM50 subtypes, and successfully distinguished between invasive lobular and ductal carcinomas in breast cancer, showcasing its robustness. It also demonstrated notable performance in predicting drug responses in cancer cell lines, with a median AUC of 0.74, surpassing nine existing methods. Furthermore, its effectiveness persists even with reduced training sample sizes. OmicsFootPrint marks an enhancement in multi-omics research, offering a novel, efficient and interpretable approach that contributes to a deeper understanding of disease mechanisms.

Objective Computer-based auditory training (CBAT) has been shown to improve outcomes in adult cochlear implant (CI) users. This study evaluates in new CI users whether starting CBAT within 3 months of activation or later impacts CI outcomes. Study Design Prospective natural experiment. Setting Tertiary academic medical center. Patients Sixty-five new adult CI users. Interventions CBAT use over the first-year postactivation. Main Outcome Measures Speech recognition scores and CIQOL-35 Profile score improvements between CI recipients who started CBAT resources early (<3 mo) and late (3–12 mo) postactivation. Results A total of 43 CI recipients started using CBAT within 3 months postactivation (early) and 22 after 3 months (late). Patients who used CBAT within 3 months postactivation showed significantly greater improvement in consonant-nucleus-consonant words (CNCw) (48.3 ± 24.2% vs 27.8 ± 24.9%; d = 0.84), AzBio Sentences in quiet (55.1 ± 28.0% vs 35.7 ± 36.5%; d = 0.62), and CIQOL-35 listening domain scores (18.2 ± 16.3 vs 6.9 ± 12.9, d = 0.73 [0.023, 1.43]), at 3 months postactivation, compared to those who had not yet initiated CBAT. However, by 12 months postactivation, after which all CI recipients had started CBAT, there were no differences observed between patients who started CBAT early or late in speech recognition scores (CNCw: d = 0.26 [−0.35, 0.88]; AzBio: d = 0.37 [−0.23, 0.97]) or in any CIQOL global or domain score (d-range = 0.014–0.47). Conclusions Auditory training with self-directed computer software (CBAT) may yield speech recognition and quality-of-life benefits for new adult CI recipients. While early users showed greater improvement in outcomes at 3 months postactivation than users who started later, both groups achieved similar benefits by 12 months postactivation.

ImportanceSince 2021, American College of Surgeons Commission on Cancer (CoC) accreditation standards require providing a survivorship program for patients with adult-onset cancer treated with curative intent. Since more than 70% of all patients with cancer in the US are treated at CoC-accredited facilities, this presents an opportunity for a landscape analysis of survivorship care availability.ObjectiveTo determine the prevalence, types, and outcomes of cancer survivorship services at CoC-accredited facilities.Design, Setting, and ParticipantsThis survey study used an anonymous, online, cross-sectional survey conducted from May 4 to 25, 2023. Participants were CoC-accredited facilities in the US representing diverse CoC program categories, institutional characteristics, geographic regions, and practice types. Department of Veterans Affairs cancer programs were excluded due to data usage restrictions. Data were analyzed from July to October 2023.ExposureCoC Survivorship Standard 4.8 was released in October 2019 and programs were expected to adhere to the Standard beginning January 1, 2021.Main Outcomes and MeasuresQuestions included self-reported survivorship program characteristics, availability of services aligned to CoC Survivorship Standard 4.8, and perceived program impacts. Response frequencies and proportions were determined in aggregate and by CoC program category.ResultsThere were 1400 eligible programs, and 384 programs participated (27.4% response rate). All regions and eligible program categories were represented, and most had analytic caseloads of 500 to 4999 patients in 2021. Most survivorship program personnel included nurses (334 programs [87.0%]) and social workers (278 programs [72.4%]), while physical (180 programs [46.9%]) and occupational (87 programs [22.7%]) therapists were less common. Services most endorsed as available for all survivors were screening for new cancers (330 programs [87.5%]), nutritional counseling (325 programs [85.3%]), and referrals to specialists (320 programs [84.7%]), while treatment summaries (242 programs [64.7%]), and survivorship care plans (173 programs [43.0%]), sexual health (217 programs [57.3%]), and fertility (214 programs [56.9%]) were less common. Survivorship services were usually delivered by cancer treatment teams (243 programs [63.3%]) rather than specialized survivorship clinics (120 programs [31.3%]). For resources needed, additional advanced practice clinicians with dedicated survivorship effort (205 programs [53.4%]) and electronic health record enhancements (185 programs [48.2%]) were most endorsed. Lack of referrals and low patient awareness were endorsed as the primary barriers. A total of 335 programs (87.2%) agreed that Survivorship Standard 4.8 helped advance their programs.Conclusions and RelevanceThese findings of this survey study of CoC-accredited programs establish a benchmark for survivorship care delivery in the US, identify gaps in specific services and opportunities for intervention, contribute to longitudinal reevaluation for tracking progress nationally, and suggest the value of survivorship care standards.

TPS2698 Background: Chimeric antigen receptor (CAR) T-cell therapies for treating solid tumors are challenging due to a lack of tumor-specific targets that discriminate cancer from normal cells. Previous studies using CEA T-cell receptors and T-cell engagers have resulted in dose-limiting, on-target, off-tumor toxicities (1,2). A2B530 is an autologous logic-gated, CEA-targeted Tmod CAR T-cell therapy that addresses the challenges of on-target, off-tumor toxicity by combining a CAR-activating receptor with a blocking receptor to discriminate tumor from normal cells (3). The activator recognizes CEA on the surface of both tumor and normal cells while specificity for tumor cells is provided by a blocker that binds HLA-A*02. In patients with both germline HLA-A*02 and tumor-associated HLA-A*02 LOH, the blocker prevents on-target, off-tumor toxicity on normal cells owing to retained HLA-A*02 expression (4). HLA-A*02 LOH can be detected using next-generation sequencing (Tempus AI, Inc.). With this definitive discriminator target, A2B530 can potentially provide a therapeutic window to treat patients with CEA-expressing solid tumors exhibiting HLA LOH. Methods: EVEREST-1 (NCT05736731) is a seamless, phase 1/2, open-label, nonrandomized study to evaluate the safety and efficacy of A2B530 in adult patients. Patients are enrolled through BASECAMP-1 (NCT04981119), a master prescreening study that identifies patients with HLA LOH at any time in the course of their disease. BASECAMP-1–eligible patients undergo leukapheresis and, when clinically appropriate, their banked T cells are manufactured for the EVEREST-1 study. The key inclusion criteria include histologically confirmed recurrent unresectable, locally advanced, or metastatic cancers associated with CEA expression: non-small cell lung, colorectal, or pancreatic cancers. Patients should have received ≥1 line of prior therapy such as checkpoint inhibitor, molecular targeted, or chemotherapy. The primary objective of phase 1 is to evaluate the safety and tolerability of A2B530 and determine the recommended phase 2 dose (RP2D). The dose-escalation portion is based on the Bayesian optimal interval design. The dose-expansion phase will confirm RP2D and collect biomarker data to further characterize A2B530. Phase 2 will assess overall response rate per RECIST v1.1. As of January 29, 2024, 8 patients have been enrolled on EVEREST-1. A2B530 was successfully manufactured for all patients, and all patients have received A2B530 infusion, with the first patient dosed in May 2023. Dose escalation is ongoing. 1. Parkhurst, et al.

ImportanceIntraocular pressure (IOP) elevations of clinical relevance have been observed after the commonly used 0.05-mL volume for intravitreous injections. However, more recently approved intravitreous agents involve volumes from 0.07 to 0.1 mL. It is not well established whether repeated 0.1-mL intravitreous injections may result in IOP-related complications.ObjectiveTo investigate the effect of 1 year of repeated 0.1-mL intravitreous injections on IOP outcomes.Design, Setting, and ParticipantsThis study was a post hoc analysis of 2 clinical trials investigating the IOP safety of intravitreous lampalizumab on geographic atrophy secondary to age-related macular degeneration. Both trials were conducted between 2014 and 2018 and recruited participants who were 50 years or older and had bilateral geographic atrophy. This post hoc analysis was performed between 2018 and 2022.InterventionsIntravitreous lampalizumab, 0.1 mL, every 4 weeks; lampalizumab, 0.1 mL, every 6 weeks; or sham procedure every 4 weeks or 6 weeks for 48 weeks.Main Outcomes and MeasuresIOP changes in the 4-week-frequency study arms and ocular adverse events to week 48 in all arms. The hypothesis for this analysis was formulated after data collection.ResultsAmong a total of 1851 participants, there was no change in mean pre-injection IOP values through 48 weeks in either arm. The adverse events glaucoma and ocular hypertension were reported for 1.8% of participants treated with lampalizumab and 1.6% of those in the sham arm.Conclusions and RelevanceOver 1 year, IOP increases were rare and did not affect treated participants more frequently than sham arm participants. These findings support the low risk of persistent IOP increases, on average, of intravitreous 0.1-mL injection volumes administered for 1 year in a manner similar to that performed in these clinical trials. These results may be valuable in the design of future therapeutic trials considering this volume for injections particularly as more recently approved agents use volumes of 0.07 to 0.1 mL.Trial RegistrationClinicalTrials.gov Identifiers: NCT02247479 and NCT02247531
