Microvessel density as a prognostic and predictive biomarker in newly diagnosed glioblastoma: correlations with radiological features and bevacizumab efficacy.

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
purposeThis study aimed to evaluate the prognostic significance of microvessel density (MVD), assessed by CD34 immunohistochemistry (IHC), and its correlation with radiological features and bevacizumab (BEV) treatment efficacy in newly diagnosed glioblastoma.
methodsWe retrospectively analyzed 41 patients with newly diagnosed glioblastoma. MVD was quantified using CD34 IHC, and patients were stratified into low and high MVD groups according to the cutoff value determined by receiver operating characteristic curve analysis (sensitivity, 76.5%; specificity, 75.0%; AUC, 0.725). Radiological characteristics-including relative cerebral blood flow (rCBF), peritumoral edema, and cystic components-were assessed. Survival outcomes were compared using Kaplan-Meier analysis. Treatment responses to temozolomide (TMZ) with or without BEV were evaluated in both MVD groups.
resultsPatients in the low MVD group exhibited significantly longer progression-free survival (PFS, p < 0.001) and overall survival (OS, p < 0.001) than those in the high MVD group. Low MVD was associated with significantly lower rCBF, less peritumoral edema, and a higher prevalence of cystic components. All six cystic-type cases were found in the low MVD group and showed favorable prognosis. The addition of BEV to TMZ significantly prolonged PFS in the high MVD group (p = 0.001) but not in the low MVD group, with no OS benefit observed in either group.
conclusionMVD serves as a prognostic biomarker and may help predict BEV treatment efficacy in glioblastoma. Combined with radiological features, MVD assessment could support more individualized therapeutic strategies. Further prospective studies using both CD34 protein and mRNA expression are warranted to validate these findings.
