Biological but not chronological age plus performance have more impact on decision making in glioblastoma patients. We investigated how progression-free survival (PFS) and overall survival (OS) in older patients with IDH wild-type glioblastoma were influenced by concomitant radio-chemotherapy and MGMT promotor methylation status in real-life settings. In total, 142 out of 273 (52%) evaluated patients were older than 65 years, and 77 (55%) of them received concomitant radio-chemotherapy. In senior patients, the initiation of concomitant radio-chemotherapy was associated with significantly better PFS: 15.3 months (CI95: 11.7–18.9) vs. 7.0 months (CI95: 4.3–9.6; p = 0.002). The favorable influence on PFS was not related to MGMT promotor methylation status as it was in the younger cohort. In seniors, concomitant radio-chemotherapy was related to significantly better OS: 20.0 months (CI95: 14.3–26.7) vs. 4.9 months (CI95: 3.5–6.2), p < 0.001. MGMT promotor methylation was related to a more favorable OS only, if concomitant radio-chemotherapy was initiated. In conclusion, more than half of the glioblastoma cohort was older than 65 years of age. Even if PFS and OS were shorter than in the younger cohort, concomitant radio-chemotherapy provided a survival advantage. In real life, MGMT promotor methylation had a positive impact on OS only if the adjuvant therapy was applied.

Metastases are the most frequent intracranial malignant tumors in adults. While Karnofsky Performance Status (KPS) and Clinical Frailty Scale (CFS) are known to have significant impact on overall survival (OS), temporal muscle thickness (TMT) has been postulated to be a promising new parameter to estimate prognosis. Patients who received a resection of one to three brain metastases in our institution were included. Temporal muscle thickness was measured in preoperative MRI scans according to a standardized protocol. In 199 patients, the mean TMT was 7.5 mm (95CI 7.3–7.7) and the mean OS during follow-up was 31.3 months (95CI 24.2–38.3). There was no significant correlation of TMT and preoperative or follow-up CFS and KPS. While CFS and KPS did significantly correlate with OS (p < 0.001 for each), no correlation was demonstrated for TMT. CFS showed a superior prognostic value compared to KPS. TMT failed to show a significant impact on OS or patient performance, whereas the clinical scales (KPS and CFS) demonstrate a good correlation with OS. Due to its superiority over KPS, we strongly recommend the use of CFS to estimate OS in patients with brain metastases.

Background/Objectives: Neurological impairment after glioma resection is a common postoperative event, but many deficits improve during recovery. The present study investigated whether transient and persistent postoperative neurological deficits differ in their association with overall survival (OS) and progression-free survival (PFS). Methods: We retrospectively reviewed data from patients who underwent initial surgical treatment for glioma in our institution. Neurological function was evaluated using documented clinical examinations performed before surgery, in the immediate postoperative period, and during routine follow-up 3–6 months after the procedure. Results: The study cohort comprised 496 patients, of whom 44.4% were women. The mean age at surgery was 60 years (95% CI, 58–61), and the average follow-up period was 21 months (95% CI, 19–23). According to the 2021 WHO classification, 80.0% of tumors were grade 4, 11.1% were grade 3, and 7.3% were grade 2. IDH mutations were absent in 81% of cases. Median survival for the entire cohort was 34 months (95% CI, 30–38). Preoperative neurological deficits, including hemiparesis, were not significantly associated with OS. Postoperative deficits that were resolved by the follow-up assessment showed no relationship with either OS or PFS, irrespective of IDH mutation status. In contrast, neurological deficits that persisted at follow-up were independently associated with shorter OS and PFS among patients with IDH-wild-type gliomas (p < 0.001), whereas no significant association was observed in the IDH-mutant subgroup. Similarly, when new neurological deficits were present at follow-up, poorer OS and PFS were predicted only in patients with IDH-wild-type tumors (p < 0.001). Conclusions: Temporary neurological deterioration following glioma surgery does not appear to adversely influence overall or progression-free survival, regardless of IDH status. However, persistent postoperative deficits, as well as newly acquired deficits that remain evident during follow-up, are strong indicators of an unfavorable prognosis in patients with IDH-wild-type gliomas.
