Survival and function in elderly patients with GBM: the role of surgical resection with contemporary multimodal therapy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeIs surgical resection associated with better overall survival and preserved functional outcomes in elderly patients with GBM compared to biopsy alone in a single-institution with homogeneous clinical protocols?
methodsWe conducted a single-surgeon, single-center retrospective cohort study of patients aged ≥ 70 years treated between 2016 and 2024 to compare survival following resection versus biopsy for lobar GBM.
resultsAmong 82 patients, 65 (79.3%) underwent resection and 17 (20.7%) biopsy. Median survival was significantly longer after resection than biopsy (8.8 vs. 2.7 months). On multivariate Cox analysis adjusting for radiation, temozolomide, MGMT status, and ASA score, resection remained associated with improved survival (HR = 0.34, 95% CI = 0.19–0.63, p < 0.001). The survival benefit persisted in both MGMT-methylated and unmethylated tumors but was observed only among patients receiving adjuvant therapy. In octogenarians, resection was independently associated with improved survival (HR = 0.28, 95% CI = 0.10–0.81, p = 0.018), with greatest benefit in MGMT-methylated tumors and those treated with temozolomide. Among patients alive with recorded ECOG assessments, 63.6%, 69.2%, and 70.8% had ECOG < 2 at 3, 6, and 12 months, respectively. Nine patients (11%) survived beyond two years; all achieved gross total resection, had MGMT-methylated tumors, and completed full adjuvant therapy.
conclusionsBy applying uniform clinical protocols, these findings support consideration of maximal safe resection in carefully selected elderly GBM patients when combined with multimodal treatment. Given the retrospective design and limited subgroup sizes, however, these findings should be considered exploratory and warrant validation in larger cohorts.
