Endocrine effects of MEK and BRAF inhibitor therapy in paediatric patients: a tertiary centre experience.
Article in Journal of neuro-oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeBRAF and MEK inhibitors are used to treat a range of paediatric tumours including low-grade gliomas. The ubiquitous nature of the BRAF/MAPK/MEK pathway means such treatments are not without side effects such as renal tubulopathies and hyperglycaemia. This study aims to describe the endocrine dysfunction observed in a cohort of children treated with BRAF and MEK inhibitors at the largest paediatric centre in the UK utilising these treatments.
methodsElectronic data for patients treated with dabrafenib (BRAF inhibitor) and trametinib (MEK inhibitor) from January 2019 to May 2022 were retrospectively reviewed. Outcomes included diagnosis of glucose dysregulation, the presence of hyponatraemia (< 135 mmol/l) and sodium nadir during treatment.
resultsA total of 55 patients were included for analysis. Nine patients had at least one hyponatraemic episode during treatment of whom three had coexisting central diabetes insipidus. A statistically significant difference (p-value = 0.037) with regards to the plasma sodium nadir during treatment was observed between patients with diabetes insipidus (median = 134 (132-137) mmol/l) and patients without (median = 137 (127-141 mmol/l). Six patients were diagnosed with a form of glucose dysregulation (e.g. insulin resistance, type 2 diabetes), of whom four were diagnosed during treatment with dabrafenib, all with hypothalamo-pituitary lesions.
conclusionClinicians using such treatments need to be aware of these potential effects, particularly the risk of hyponatraemia in patients with pre-existing central diabetes insipidus and monitor for these accordingly, including performing measurements of sodium and glucose prior to, during and after treatment.
