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

Pediatric brain tumors are highly prevalent and remain one of the leading causes of cancer-related deaths in children. There are numerous different brain tumor types that are now well characterized by magnetic resonance imaging (MRI), patient clinical course, and neuropathological and molecular genetic alterations. One of the challenges with treating pediatric brain tumors with systemic chemotherapy is the inability of several chemotherapeutic agents to cross the blood-brain barrier (BBB), which serves as a protective mechanism for neuronal homeostasis. The BBB primarily comprises microvascular endothelial tight junctions. Controlling BBB permeability to allow for therapeutics to cross and combat brain tumors is now possible using MR-guided focused ultrasound (MRgFUS). In this approach, microbubbles are administered intravenously prior to MRgFUS BBB disruption at the targeted tumor site in the brain. In the presence of MRgFUS, the microbubbles in the brain capillaries oscillate and temporarily disrupt the BBB, enabling systemically administered chemotherapy drugs to cross at the targeted site. In this review, we provide evidence supporting the use of MRgFUS BBB disruption to treat brain tumors in animal models and in ongoing human clinical drug trials. We conclude with efforts to harness the potency of the immune system using MRgFUS against pediatric brain tumors.
