1 · What the graph read from it

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.

2 · The registry

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

objectivesRecent preclinical studies suggest that treating glioblastoma (GBM) with a combination of targeted chemotherapy and radiotherapy may enhance the anti-tumor effects of both therapies. However, the effects of these treatments on glioma growth and progression are poorly understood.

methodsIn this study, we have tested the effects of combination therapy in a mouse glioma model that utilizes a PDGF-IRES-Cre-expressing retrovirus to infect adult glial progenitors in mice carrying conditional deletions of Pten and p53. This model produces tumors with the histological features of GBM with 100% penetrance, making it a powerful system to test novel treatments. Sunitinib is an orally active, small molecule inhibitor of multiple receptor tyrosine kinases critical for tumor growth and angiogenesis, including PDGF receptors. We investigate the addition of Sunitinib to radiotherapy, and use bioluminescence imaging to characterize the effects of treatment on glioma growth and progression.

resultsTreating our PDGF-driven mouse model with either Sunitinib or high-dose radiation alone delayed tumor growth and had a modest but significant effect on survival, while treating with low-dose radiation alone failed to control glioma growth and progression. The addition of Sunitinib to low-dose radiation caused a modest, but significant delay in tumor growth. However, no significant survival benefit was seen as tumors progressed in 100% of animals. Histological analysis revealed a reduction in vascular proliferation and a marked increase in brain invasion. An additional study combining Sunitinib with high-dose radiation revealed a fatal toxicity despite individual monotherapies being well tolerated. DISCUSSION: These results show that the addition of Sunitinib to radiotherapy fails to significantly alter survival in GBM despite enhancement of the effects of radiation. Furthermore, an enhanced risk of toxicity associated with combined therapy must be considered in the design of future clinical studies.
