Background: Resuming professional activity after awake surgery for diffuse low-grade glioma (DLGG) is an important goal, which is not reached in every patient. Cognitive deficits can occur and persist after surgery. In this study, we analyzed the impact of mild cognitive impairments on the work resumption. Methods: Fifty-four surgeries (including five redo surgeries) performed between 2012 and 2020 for grade 2 (45) and 3 (nine) DLGG in 49 professionally active patients (mean age 40 [range 23–58.) were included. We retrospectively extracted the results of semantic and phonemic verbal fluency tests from preoperative and 4-month postoperative cognitive assessments. Patients were interviewed about their working life after surgery, between April and June 2021. Results: Patients (85%) returned to work, most within 3 to 6 months. Patients (76%) reported subjective complaints (primarily fatigue). Self-reported symptoms and individual and clinical variables had no impact on the work resumption. Late-postoperative average Z-scores in verbal fluency tasks were significantly lower than preoperative for the entire cohort (Wilcoxon test, p < 0.001 for semantic and p = 0.008 for phonemic fluency). The decrease in Z-scores was significantly greater (Mann Whitney U-test, semantic, p = 0.018; phonemic, p = 0.004) in the group of patients who did not return to work than in the group of patients who did. Conclusion: The proportion of patients returning to work was comparable to similar studies. A decrease in verbal fluency tasks could predict the inability to return to work. [ABSTRACT FROM AUTHOR]

Purpose: Maximal safe tumor resection is the first line of treatment for IDH-mutated gliomas. However, when upfront surgical resection is deemed unsatisfactory due to tumor size and location, chemotherapy could represent an interesting alternative for reducing glioma extension and allowing for a safer and more efficient removal. Methods: We performed a retrospective study (June 2011 to December 2021) on patients with IDH-mutated gliomas undergoing chemotherapy with a neoadjuvant intent, followed by surgical excision in awake conditions. MRI-imaging follow-up was conducted every 3–6 months. Neuropsychological assessments (NPSA) were performed for all patients before surgery, during post-operative period, and at later follow-up, and patients were periodically interviewed about their clinical and job status. Results: We included 6 patients who underwent awake surgery after neoadjuvant chemotherapy (temozolomide in 5 cases, PCV in 1 case) for an IDH-mutated glioma (3 oligodendrogliomas and 3 astrocytomas). Median tumor volume reduction was 47%, allowing for complete resection in one patient, subtotal resection in 4 patients, and partial resection in 1 patient. No major adverse effects were observed under chemotherapy. At the 4 months NPSA, a worsening of flexibility was observed in 2 patients (verbal fluencies in one case and trail making test in the other). Three out of the four patients working full time before procedure resumed their job full time, after a 7 to 10 months delay. Conclusion: Neoadjuvant chemotherapy followed by maximal safe resection can be offered to patients affected by IDH-mutated gliomas for whom upfront surgery would be inadequate. More studies are necessary given the limited size of our sample. [ABSTRACT FROM AUTHOR]
