Treating oligodendroglioma - An analysis of a homogeneous 1p/19q-codeleted and isocitrate dehydrogenase-mutant patient cohort.

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
Background: Oligodendrogliomas (ODG) are rare, diffusely infiltrating brain tumors, defined by their 1p/19q-codeletion and isocitrate dehydrogenase (IDH) mutation. Herein, we analyze the influence of various tumor and patient characteristics on progression-free survival (PFS) and overall survival (OS) in a homogeneous patient cohort. Material and methods: Patients treated for a 1p/19q-codeleted and IDH-mutant ODG were evaluated. The patient and tumor characteristics were analyzed for their influence on PFS and OS. Results: One-hundred-fourteen patients met the inclusion criteria. The median clinical and radiographic follow-up periods were 68.6 and 69.8 months. The median PFS and OS were 66.9 and 236.0 months, respectively. The 2-, 4- and 6-year PFS rates were 89.5%, 76.3%, and 46.0%. The 2-, 4- and 6-year OS rates were 99.0%, 97.9%, and 96.2%. For WHO grade 2 ODG, extent of resection ( Conclusion: Whereas previous studies often comprise tumors with IDH wild type status and without 1p/19q-codeletion, this homogeneous ODG cohort, as defined by the current WHO classification, demonstrated PFS benefits for various therapies, especially concerning RCT. While this is generally in accordance with comparable studies, more prospective work on homogeneous patient cohorts is required to refine treatment guidelines and to determine the role of TMZ in ODG.
