Abstract
BACKGROUND: Previous observational studies have been controversial regarding the association of leukocyte telomere length (LTL) with prostate cancer (PCa) and benign prostatic hyperplasia (BPH).</p>
METHODS: First, we conducted an observational study utilizing UK Biobank data. The correlation between LTL and the risk of PCa and BPH was evaluated via multivariate-adjusted logistic regression. Then, we conducted a 2-sample Mendelian randomization to examine causal links between LTL (472 174 individuals) and PCa as well as BPH. To verify the reliability of the primary analysis, we conducted a second analysis and sensitivity analyses.</p>
RESULTS: In the UK Biobank study, individuals in the longer quartiles of LTL were observed to have a higher risk of PCa (1.155-fold to 1.349-fold, all p < .001) and BPH (1.119-fold to 1.212-fold, all p < .001) compared to those in the lowest quartile in multivariate-adjusted logistic regression. We observed that genetically predicted longer LTL resulted in a 1.427-fold risk of PCa (odds ratio [OR] = 1.427, 95% confidence interval [CI] = 1.197-1.702, p < .001) and 1.539-fold risk of BPH (OR = 1.539, 95% CI = 1.387-1.707, p < .001) in the primary analysis. In the second analysis, the results also indicated that longer LTL increased the genetic liability to both PCa (OR = 1.338, 95% CI = 1.189-1.507, p < .001) and BPH (OR = 1.006, 95% CI = 1.003-1.008, p < .001). Sensitivity analyses also supported the reliability of the results.</p>
CONCLUSIONS: Our study provides convincing evidence supporting that longer LTL increases the risk of PCa and BPH in European individuals. Large-scale studies are needed to elucidate the potential mechanisms of LTL in PCa and BPH occurrence.</p>
