PURPOSE The COSMIC-021 study assessed the safety and efficacy of cabozantinib plus atezolizumab in advanced solid tumors. Presented here are results from the expansion cohorts with advanced urothelial carcinoma (UC). METHODS This phase Ib study (ClinicalTrials.gov identifier: NCT03170960 ) enrolled patients with inoperable locally advanced/metastatic UC into four tumor cohorts: first-line cisplatin-eligible (cis-eligible), first-line cisplatin-ineligible (cis-ineligible), previous platinum-containing chemotherapy (previous chemotherapy-treated), and previous immune checkpoint inhibitor (ICI)–treated. Patients received oral cabozantinib 40 mg once daily and intravenous atezolizumab 1,200 mg once every 3 weeks. The primary end point was objective response rate (ORR), as assessed by the investigator per RECIST v1.1 every 6 weeks for 12 months and every 12 weeks thereafter; the secondary end point was safety. RESULTS A total of 121 patients (previous ICI-treated cohort, n = 31, and each of the other cohorts, n = 30) received study treatment from March 2018 to November 2021. The ORR (95% CI) was 30% (15 to 49) for cis-eligible, 20% (8 to 39) for cis-ineligible, 27% (12 to 46) for previous chemotherapy-treated, and 10% (2 to 26) for previous ICI-treated cohorts. The median progression-free survival (95% CI) was 5.5 (1.6 to 11.6), 5.6 (3.1 to 11.1), 5.4 (1.6 to 7.6), and 3.0 (1.8 to 5.5) months, respectively. Grade 3 or 4 treatment-related adverse events (TRAEs) were experienced by 43%, 67%, 57%, and 45% of patients, respectively. TRAEs led to discontinuation of all treatment components in 17%, 13%, 3%, and 19%, respectively. No grade 5 TRAEs were reported in any cohort. CONCLUSION The novel combination of cabozantinib plus atezolizumab exhibited clinical activity in advanced UC that is cis-eligible, cis-ineligible, or previously treated with platinum-containing chemotherapy; clinical activity in previous ICI-treated UC was modest. The toxicity profile was consistent with that previously reported for the combination.

PURPOSE Idecabtagene vicleucel (ide-cel) and ciltacabtagene autoleucel (cilta-cel), two B-cell maturation antigen–directed chimeric antigen receptor (CAR) T-cell therapies have demonstrated remarkable efficacy in relapsed/refractory multiple myeloma (RRMM). We compare safety, efficacy, and survival among patients with RRMM treated with standard-of-care (SOC) ide-cel or cilta-cel. METHODS Data were from a retrospective chart review of patients with RRMM leukapheresed by December 31, 2022, with the intent to receive SOC ide-cel or cilta-cel at 19 institutions. An inverse probability of treatment weighting (IPTW) approach was used to compare outcomes by therapy type. RESULTS A total of 641 patients were leukapheresed by December 31, 2022, with ide-cel (n = 386) and cilta-cel (n = 255). Five hundred eighty-six patients were infused (n = 350 for ide-cel; n = 236 for cilta-cel) with a median follow-up of 12.6 and 13.0 months for ide-cel and cilta-cel, respectively. After IPTW, patient characteristics were well balanced. Cilta-cel was associated with higher likelihood of grade ≥3 cytokine release syndrome (CRS; odds ratio [OR], 6.80 [95% CI, 2.28 to 20.33]), infections (OR, 2.03 [95% CI, 1.41 to 2.92]), second primary malignancies (OR, 1.77 [95% CI, 0.89 to 3.56]), and delayed neurotoxicity (OR, 20.07 [95% CI, 4.46 to 90.20]). Cilta-cel was also associated with better treatment responses (≥complete response: OR, 2.42 [95% CI, 1.63 to 3.60]), longer progression-free survival (hazard ratio [HR], 0.48 [95% CI, 0.36 to 0.63]), and longer overall survival (HR, 0.67 [95% CI, 0.46 to 0.97]). No associations were observed between therapy type and immune effector cell–associated neurotoxicity syndrome, any CRS, severe cytopenia at days 30 and 90, or nonrelapse mortality. We observed consistent findings when repeating the analyses restricting the ide-cel cohort to patients infused during the same time period as Food and Drug Administration approval for cilta-cel (≥March 2022). CONCLUSION Cilta-cel demonstrated superior efficacy and survival, with higher incidence of certain toxicities, compared with ide-cel.

Objective To identify the incidence of positive autoimmune laboratory markers in idiopathic sudden sensorineural hearing loss (iSSNHL) and its impact on hearing prognosis. Study Design Retrospective cohort database study Setting A collaborative national database (TriNetX) sourced from 79 large healthcare organizations in the United States. Patients Adults (≥18 years old) diagnosed with iSSNHL (ICD-10 H91.2) treated with systemic steroids. Interventions Autoimmune laboratory markers and salvage intratympanic (IT) steroids for SSNHL (CPT 69801). Main Outcome Measures 1) Positivity of autoimmune laboratory markers—rheumatoid factor (RF), ANCA, DNA double strand antibody (Ab), Sjogren syndrome A and B Abs, SCL-70 Ab, cardiolipin IgG Ab, Jo-1 Ab, ANA, mitochondria Ab. 2) Percent of patients that underwent salvage IT steroids, cochlear implantation, or hearing aid evaluation—all utilized as a proxy for hearing outcomes. Results Subjects with iSSNHL who had autoimmune testing (n = 17,413) were marginally more likely to be positive for at least one autoimmune laboratory marker compared to subjects without iSSNHL (n = 17,413; 23.0% vs. 21.4%, p = 0.0006). Statistical significance was lost after removing nonspecific autoimmune markers, however. Of those with iSSNHL who received systemic steroid treatment, subjects with positive autoimmune markers (n = 5,153) versus negative autoimmune markers (n = 5,153) underwent similar rates of salvage IT steroids (7.1% vs. 7.8%, p = 0.154), hearing aid evaluation (2.76% vs 2.47%, p = 0.354), and cochlear implantation (1.65% vs. 1.69%, p = 0.878). Conclusions Patients with iSSNHL have a marginally higher incidence of nonspecific positive autoimmune laboratory markers compared to those without iSSNHL; however, the presence of these markers does not predict treatment response or prognosis. Specifically, autoimmune markers did not predict the need for salvage IT steroids, nor CI and hearing aid use in iSSNHL. Autoimmune laboratory testing may be useful in iSSNHL patients with additional symptoms suspicious for an autoimmune disorder; however, a generalized screening is not recommended as it is unlikely to alter management or prognosis.

Objective To examine the quality of information provided by artificial intelligence platforms ChatGPT-4 and Claude 2 surrounding the management of vestibular schwannomas. Study design Cross-sectional. Setting Skull base surgeons were involved from different centers and countries. Intervention Thirty-six questions regarding vestibular schwannoma management were tested. Artificial intelligence responses were subsequently evaluated by 19 lateral skull base surgeons using the Quality Assessment of Medical Artificial Intelligence (QAMAI) questionnaire, assessing “Accuracy,” “Clarity,” “Relevance,” “Completeness,” “Sources,” and “Usefulness.” Main Outcome Measure The scores of the answers from both chatbots were collected and analyzed using the Student t test. Analysis of responses grouped by stakeholders was performed with McNemar test. Stuart-Maxwell test was used to compare reading level among chatbots. Intraclass correlation coefficient was calculated. Results ChatGPT-4 demonstrated significantly improved quality over Claude 2 in 14 of 36 (38.9%) questions, whereas higher-quality scores for Claude 2 were only observed in 2 (5.6%) answers. Chatbots exhibited variation across the dimensions of “Accuracy,” “Clarity,” “Completeness,” “Relevance,” and “Usefulness,” with ChatGPT-4 demonstrating a statistically significant superior performance. However, no statistically significant difference was found in the assessment of “Sources.” Additionally, ChatGPT-4 provided information at a significant lower reading grade level. Conclusions Artificial intelligence platforms failed to consistently provide accurate information surrounding the management of vestibular schwannoma, although ChatGPT-4 achieved significantly higher scores in most analyzed parameters. These findings demonstrate the potential for significant misinformation for patients seeking information through these platforms.

Abstract Primary central nervous system lymphoma (PCNSL) is a rare form of non-Hodgkin lymphoma involving the brain, cerebrospinal fluid, or retina/vitreous without systemic involvement. Induction with high-dose methotrexate (HD-MTX) followed by consolidation with autologous stem cell transplant (auto-SCT) has become the standard treatment paradigm for most patients. However, limited data are available regarding the efficacy of a maintenance approach with HD-MTX. Herein, we retrospectively reviewed the characteristics and outcomes of 148 patients diagnosed with PCNSL between October 2010 and June 2022, who underwent HD-MTX–based induction therapy followed by either auto-SCT consolidation (n = 70) or HD-MTX maintenance therapy (n = 37). At a median follow-up time of 4.5 years, the progression-free survival (PFS) was 8.3 years and the overall survival (OS) was not reached. Compared to patients who underwent auto-SCT, patients who received maintenance HD-MTX had a higher median age at diagnosis of 72 vs 62 years and a trend toward higher proportion of patients being Eastern Cooperative Oncology Group 2 or higher (41% vs 29%). At 5-years postinduction treatment initiation, the PFS rates in the auto-SCT cohort and HD-MTX maintenance cohort were 74.6% and 72.6%, respectively, and the OS rates were 76.0% and 82.4%, respectively. Overall, there was no significant difference in PFS or OS based on postinduction management strategy. Our data suggest that maintenance HD-MTX may be a reasonable, time-limited treatment strategy for patients with PCNSL responding to initial induction therapy.

ImportanceAcute pulmonary embolism (PE) is a major cause of morbidity and mortality in patients with cancer in the US and worldwide.ObjectivesTo assess the trends in PE-related mortality from 2011 to 2020 among US patients with cancer across age, sex, ethnic and racial groups, urbanicity, and regionality.Design, Setting, and ParticipantsThis cohort study used the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research data system to determine national trends in age-adjusted mortality rates (AAMRs) due to acute PE among US patients with cancer aged 15 years or older from January 2011 to December 2020. Concomitant trends in cancer mortality and incidence that may have contributed to PE-related mortality were obtained from US Cancer Statistics. Data were analyzed from September to November 2024.ExposurePE-related mortality.Main Outcomes and MeasuresThe primary outcome was PE-related deaths among individuals with cancer. AAMRs and cancer incidence were assessed using joinpoint regression modeling, expressed as an average annual percentage change (AAPC) with relative 95% CIs.ResultsFrom 2011 to 2020, a total of 27 280 194 individuals aged 15 years or older (13 897 519 male [50.9%]; 13 382 675 female [49.1%]) died in the US. The AAMR for PE-related mortality in patients with cancer increased during this time period (AAPC, 2.5%; 95% CI, 1.4% to 3.6%; P = .001), without differences between sexes (P for parallelism = .38). The AAMR increased among those aged 15 to 64 years (AAPC, 3.2%; 95% CI, 1.9% to 4.6%; P = .001), non-Hispanic and non-Latinx White individuals (AAPC, 2.7%; 95% CI, 1.52% to 3.94%; P = .001), non-Hispanic and non-Latinx Black or African American individuals (AAPC, 2.2%; 95% CI, 0.7% to 3.7%; P = .001), Hispanic and Latinx individuals (AAPC, 2.6%; 95% CI, 0.7% to 4.5%; P = .006), and among individuals residing in the Southern US (AAPC, 3.7%; 95% CI, 1.3% to 6.2%; P = .003). During the same period, age-adjusted cancer incidence and cancer-related mortality decreased while the absolute number of new cancer diagnoses and cancer-related deaths increased.Conclusions and RelevanceThis cohort study found that despite decreases in cancer-related mortality rates, age-adjusted PE-related mortality in US patients with cancer increased over the last decade; concerning trends included rising PE-related mortality in younger individuals aged 15 to 64 years, particular ethnic and racial groups, and the Southern region of the US. Recognition of such patterns may inform further research into thromboprophylaxis and treatment of PE as a complication of cancer and cancer-directed therapy.

Background and Objectives: Hearing loss is relatively common in older individuals, and individuals with frontotemporal lobar degeneration (FTLD) are no exception; this can exacerbate communication difficulties stemming from speech-language impairments. The co-occurrence of these symptoms can contribute to increased frustration and isolation for patients and their communication partners. The objective of this study was to evaluate the feasibility of self-administered hearing testing. Ultimately, this could be administered remotely, which would increase access to assessment and inform management for this population. Method: Seventeen patients with underlying FTLD, clinically presenting with progressive apraxia of speech with and without agrammatic aphasia, independently completed the Home Hearing Test supervised while in office. Results: Three patients self-reported hearing loss, but results for 100% recommended formal evaluation. Eleven patients demonstrated good test accuracy. Six patients had “poor” or not computable accuracy; among them, five had evidence of cognitive impairment and/or behavioral changes, and one had known severe hearing loss, although differences between those with good and poor test accuracy were not significant. Patients with poor test accuracy had more difficulty with limb praxis. Conclusions: Most participants independently completed the test, though some had reduced test accuracy that may have been associated with cognitive impairment and/or limb apraxia. This study supports the need for hearing screenings in all patients with progressive apraxia of speech and aphasia and highlights both the feasibility and caution required in implementing self-administered testing protocols. Further work should evaluate the feasibility of in-home hearing screenings in a broader range of FTLD phenotypes and directly compare sensitivity and specificity of hearing loss detection with in-clinic administration.

Background: Early surgical intervention in nerve palsies with a high probability of nerve integrity and natural recovery risks unnecessary surgery. Understanding the variables influencing surgeons to offer surgery might provide insight into variations in surgeon beliefs and guide treatment recommendations. Methods: Sixty-nine surgeons of the Science of Variation Group participated in a survey consisting of 6 traumatic and 3 nontraumatic nerve palsy scenarios. Participants were asked what their preferred treatment was and how likely they were to offer surgery on a scale from 0 to 10. Participants were randomized to choose for themselves (n = 31) or for a patient of their age and sex (n = 38). Results: There was no difference in the overall likelihood of offering surgery or in the types of treatment offered to patients compared with oneself. Surgery was least recommended for idiopathic palsies and most for ulnar (β = 0.91; 95% CI, 0.10 to 1.7; P = 0.027) or radial (β = 0.92; 95% CI, 0.12 to 1.7; P = 0.025) nerve palsy following closed distal radius or humerus fractures. Longer symptom duration increased the likelihood of offering surgery. Conclusions: Surgeons were moderately likely to recommend surgery for nerve palsies, with no variation in opinions regardless of whether they were deciding for themselves or for patients. For specific nerve palsies with a documented benign natural history, this likely represents overtreatment. Future studies can assess whether balancing awareness of a benign natural history with the pressure to act and the sense that recovery is “taking too long” might limit the offer of unnecessary surgery.
