Summary
This Mendelian randomisation study investigated causal relationships between specific gut microbial taxa and five urological cancers, addressing limitations of observational studies through genetic instrumental variable analysis. The authors identified distinct microbial associations for each cancer type—including taxa from Rikenellaceae, Ruminococcus, Oscillibacter, and other genera—and employed comprehensive sensitivity analyses to validate findings. The study provides genetic evidence for a role of the gut microbiota in urological cancer aetiology, though the mechanisms underlying these associations remain to be elucidated.
UK applicability
The findings are derived from UK Biobank data and are therefore directly relevant to UK population health and microbiota-cancer associations. These results could inform UK dietary and microbiota-targeted interventions for urological cancer prevention, though translation to clinical practice would require mechanistic studies and prospective validation.
Key measures
Genetic variants associated with gut microbial taxa (from MiBioGen consortium GWAS); genetic associations with urological cancers (from UK Biobank and FinnGen); Wald ratio and inverse variance weighted estimates; sensitivity analyses to test causal robustness
Outcomes reported
The study identified specific gut microbial taxa causally associated with five types of urological cancer (bladder, prostate, renal cell, renal pelvis, and testicular cancer) using Mendelian randomisation analysis. Sensitivity analyses were conducted to confirm the robustness and reliability of the causal associations identified.
