Associations between eosinophils and cancer risk in the UK Biobank.

Eosinophils exhibit anti-tumor cytotoxic responses in the tumor microenvironment and may contribute to tumor immunosurveillance. To assess the relationship between circulating eosinophils and cancer risk, we analyzed data from 443,542 adults aged 38-73 in the UK Biobank, who were initially cancer-free, had over a year of follow-up, and baseline white blood cell count measurements. Using multivariable Cox regression, we estimated hazard ratios (aHR) and 95% confidence intervals (95%CI) for each quartile increase in absolute eosinophil count (AEC) across 58 cancer types, adjusting for relevant confounders.

EBV-Associated Gastric Cancer; An In Situ Hybridization Assay on Tissue Microarray: A Multi-Region Study from Four Major Provinces of Iran.
