Objective:
To investigate differences in serum uric acid levels between elderly patients with prostate cancer and patients with benign prostatic hyperplasia(BPH).Methods:
A total of 300 prostate cancer patients admitted to the urology department of our hospital between Feb.2010 and Jun.2019 were retrospectively analyzed.During the same period, 240 BPH patients and 400 elderly men with normal prostate size were enrolled as the control group.Serum uric acid and prostate-specific antigen(PSA)levels, C-reactive protein(CRP), neutrophil count and lymphocyte count were determined.Serum uric acid concentrations were monitored in prostate cancer patients with different clinicopathological characteristics.Results:
CRP and Neu/Lym levels were higher in the prostate cancer group than in the BPH and control groups( P<0.05). The serum uric acid level was (327.0±58.3)μmol/L in the prostate cancer group, lower than in the BPH group(375.2±68.4)μmol/L and the control group(377.8±73.2)μmol/L( F=55.69, P<0.001). Multivariable Logistic regression analysis indicated that serum uric acid was a protective factor for prostate cancer( OR=0.593, 95% CI 0.542-0.718, P=0.004). There were significant differences in serum uric acid levels between prostate cancer patients with different ages and pathological grades( t=-4.63, F=12.73, P<0.001). However, serum uric acid levels were not significantly correlated with clinical staging or lymph node metastasis( F=-2.72 and 0.77, P=0.068 and 0.460).Conclusions:
Compared with BPH patients and healthy males, serum uric acid levels are reduced and inflammatory markers are increased in prostate cancer patients, indicating that serum uric acid may be a risk factor for the occurrence and progression of prostate cancer in the elderly.
