When only the subjects with DM were divided into two groups (group 1 and 2) according to HbA1c level (&lt;6.5% vs. \u22656.5%), group 2 demonstrated significantly higher rate of extraprostatic extension of tumor (<jats:italic>P<\/jats:italic>\u2009=\u20090.043) and high (\u22657) pathological Gleason score (<jats:italic>P<\/jats:italic>\u2009=\u20090.005) than group 1. Also among those with DM, HbA1c level was observed to be an independent predictor for high pathologic Gleason score (<jats:italic>P<\/jats:italic>\u2009=\u20090.010) and extraprostatic extension of tumor (<jats:italic>P<\/jats:italic>\u2009=\u20090.035), respectively in multivariate analyses.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>Although simple history of having DM may not be a significant factor regarding aggressiveness of clinically localized prostate cancer, the glycemic control, as represented by HbA1c level, may be a useful preoperative predictor of aggressive tumor profile among patients with DM who are also diagnosed with clinically localized prostate cancer.
