Abstract

BACKGROUND: Sex hormone-binding globulin (SHBG) plays a critical role in regulating androgen bioavailability and has been hypothesized to influence prostate cancer risk, though existing evidence is inconsistent. This systematic review and meta-analysis aimed to evaluate the association between SHBG levels and prostate cancer risk.

METHODS: A comprehensive search was conducted across PubMed, Embase, and Web of Science for studies published up to December 1, 2024. Observational studies assessing SHBG levels and prostate cancer risk were included. Effect sizes were pooled using random-effects meta-analysis. Heterogeneity was evaluated using the I2 statistic, and quality assessment was performed using the Newcastle-Ottawa Scale. Statistical analysis was performed using R software version 4.4.

RESULTS: Sixteen studies, including 720,298 participants and 90,799 prostate cancer cases, were analyzed. The pooled odds ratio (OR) for prostate cancer risk per unit increase in SHBG was 0.907 (95% CI 0.799-1.030), indicating no statistically significant association. Substantial heterogeneity was observed among the included studies (I2 = 79%; P
