24. Predictive Value of Neurosurgery Applicant Metrics on Resident Academic Productivity.

Author

Abstract

Background and Objectives: Scholarship has been critical to neurosurgery. As grades and board examinations become pass-fail, finding metrics to distinguish applicants coupled with an emphasis on research has led to growth of reported academic output among neurosurgery applicants. We aimed to evaluate applicant factors that associate with an academically productive neurosurgery resident., Methods: Applicant characteristics were extracted from Electronic Residency Application Service archives from 2 geographically distinct neurosurgical programs for the 2014 to 2015 match cycle. Publications during residency were quantified, and residency careers were examined. Factors associated with residency publications were examined using univariate and multivariate regressions., Results: A total of 228 United States (US) applicants to neurosurgery were assessed (89% of US neurosurgery applicants), with 173 matching across 93 programs. The average publication number of matched applicants was higher at 6.6 (median: 4, range: 0-43) that of than unmatched applicants (mean: 2.9, median: 1, range: 0-51). A total of 93.1% of publications were substantiated on PubMed review. Matched candidates published 19.3 manuscripts (median: 13, range: 0-120) on average during residency. On univariate analysis, factors associated with higher residency publications included taking a non-degree-granting extra year for research in medical school, consistently high clerkship grades, depth of preresidency research involvement, number of coresidents, program R25 status, and academic output of neurosurgery department leadership. After multivariate correction, the training environment played an outsized role in predicting resident academic output, with program R25 status significantly associated with resident academic output (odds ratio: 1.25, P = .012). Taking an extra research year in medical school approached but was not significant (odds ratio: 1.19, P = .099). Twelve matched international medical school graduates (IMGs) were also assessed (75% of matched IMG neurosurgery applicants). IMGs exhibited higher total publications and conference abstracts than US matched applicants and also published more during residency., Conclusion: Cultivating an environment that promotes research endeavors is critical for neurosurgical resident academic growth. Preresidency publication number does not predict publication potential during residency., (Copyright © Congress of Neurological Surgeons 2024. All rights reserved.)

25. Gene Expression Changes Associated With Recurrence After Gross Total Resection of Newly Diagnosed World Health Organization Grade 1 Meningioma.

Author

Abstract

Background and Objective: Patients who undergo gross total resection (GTR) of Central Nervous System World Health Organization (WHO) grade 1 meningioma constitute a "low-risk" group, but some low-risk meningiomas can recur despite reassuring clinical and histological features. In this study, gene expression values in newly diagnosed WHO grade 1 meningiomas that had undergone GTR were evaluated for their association with recurrence., Methods: This was a retrospective, international, multicenter cohort study that included WHO grade 1 meningiomas that underwent GTR, as first treatment, based on postoperative magnetic resonance imaging. Normalized gene expression values from a previously validated 34-gene panel were evaluated for their association with recurrence. Kaplan-Meier, multivariable Cox proportional hazard analyses, and K-means clustering were performed to assess the association of genes of interest with recurrence and identify molecular subgroups among clinically and histologically low-risk meningiomas., Results: In total, 442 patients with WHO grade 1 meningiomas that underwent GTR and had available gene expression profiling data were included in the study. The median follow-up was 5.0 years (interquartile range 2.6-7.7 years), local recurrence occurred in 36 patients (8.1%), 5-year local freedom from recurrence was 90.5%, and median time to recurrence was 2.9 years (range 0.5-10.7 years). Eleven genes were associated with local recurrence, including lower expression of ARID1B, ESR1, LINC02593, PGR, and TMEM30B and higher expression of CDK6, CDKN2C, CKS2, KIF20A, PGK1, and TAGLN. Of these genes, PGK1 had the largest effect size. K-means clustering based on these 11 genes distinguished 2 molecular groups of clinically and histologically low-risk meningiomas with significant differences in local freedom from recurrence (hazard ratio 2.5, 95% CI 1.2-5.1, P = .016)., Conclusion: Gene expression profiling may help to identify newly diagnosed WHO grade 1 meningiomas that have an elevated risk of recurrence despite GTR., (Copyright © Congress of Neurological Surgeons 2024.
