Lifestyle Risk Factors Associated with Adult Primary Brain Tumours: Quality Assessment of Existing Systematic Reviews, Followed by Updated Analyses and De-Novo Syntheses

Background: A compilation of high quality systematic reviews (SRs) on lifestyle factors associated with adult glioma and meningioma was developed.
Methods and Materials: Phase 1 consisted of a systematic overview of existing SRs. For Phase 2, high quality SRs were incorporated in an update. Moderate or low quality SRs which had not been considered in a high quality review were eligible for a de-novo synthesis.
Results: Phase 1 resulted in seven moderate to low quality reviews. From this, in Phase 2, smoking, mobile phone and hair dye use were subjected to de-novo reviews. For smoking, it was suggestive that past smokers had an increased risk. For mobile phone use, there was no overall association, however it was suggestive that ipsilateral and high cumulative call time were associated with slight increased risk. No association was observed for personal hair dye use.
Conclusions: Despite these null associations, rigorous SR methods were used providing confidence in conveying these results.
