Evidence for intrathecal sodium butyrate as a novel option for leptomeningeal metastasis.
Article in Journal of neuro-oncology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionThe prognosis for leptomeningeal metastasis (LM) remains extremely poor regardless of intrathecal chemotherapy with various drugs, and thus, new treatments are necessary. Butyrate is an endogenous 4-carbon saturated fatty acid, has been investigated as an anti-tumor agent because of its multiple suppressive effects on several tumors. In this study, we investigated the cellular basis of sodium butyrate (SB), a sodium salt compound of butyrate, in vitro and evaluated the clinical potential of intrathecal SB administration for LM in vivo.
methodsWe examined SB's effects on Walker 256 rat mammary tumor cells with regard to cytotoxicity, cell morphology, colony formation, migration, and invasion. We also examined SB's neurotoxicity for primary neurons and primary astrocytes. We finally evaluated the potency of continuous intrathecal SB administration in rats with intrathecally transplanted breast tumors as an LM model.
resultsPhysiological SB concentrations (2-4 mM) induced growth suppression, morphological changes, and inhibition of migration and invasion, but did not exhibit neurotoxic effects on primary neurons and astrocytes. Continuous intrathecal SB administration in a rat LM model significantly increased survival periods with little neurotoxicity.
conclusionsContinuous intrathecal SB administration significantly improved prognoses in a rat LM model, which suggests that SB is a promising therapy for LM.
