Pregnancy and neonatal outcomes in patients treated for glioma before or during pregnancy: a single-institution retrospective series.
Article in Journal of neuro-oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundGlioma diagnosed during pregnancy and pregnancy following glioma treatment present complex management challenges. Safety of glioma treatment during pregnancy is not well established. The ability to counsel patients on timing of conception after treatment remains limited. The aim of this study was to describe our institution's experience with pregnancy during and/or after treatment for glioma.
methodsIn this single-institution study, we retrospectively identified patients diagnosed with glioma during or prior to pregnancy and described treatment courses and maternal and neonatal outcomes.
resultsTwenty-one female patients were included. Glioma diagnoses included 12 high-grade tumors and 9 low-grade tumors. Cohort A consisted of 8 patients who presented with glioma during pregnancy, of which, 7 underwent glioma treatment during pregnancy. All pregnancies in cohort A were without significant maternal complications and resulted in delivery of a healthy neonate. Cohort B consisted of 13 patients who experienced pregnancy after a prior diagnosis of glioma, totaling 18 pregnancies that resulted in delivery of a neonate. Antepartum course was complicated by seizure in 3/18 pregnancies. Functionally inconsequential anatomic abnormalities in childhood offspring of cohort B occurred in 5/18 pregnancies. Anatomic abnormalities occurred in 4/13 (31%) of temozolomide exposed offspring and 1/5 (20%) of temozolomide unexposed offspring.
conclusionsIn this retrospective series, diagnosis of glioma before or during pregnancy was associated with generally favorable maternal, fetal and childhood outcomes. We observed higher-than-expected rate of anatomic abnormalities in the post-diagnosis cohort, though none carried meaningful functional consequences. These findings add to the limited literature exploring pregnancy outcomes in patients with glioma.
