RESUMO
Background: It has been hypothesized that men with long term diabetes have a lower risk of prostate cancer then non-diabetic men. Whether diabetes influences level of biomarkers such as prostate specific antigen (PSA), which is involved in the detection of prostate cancer is, unknown. In view of the aforementioned controversial literature, it was decided to evaluate this relation-ship in non-diabetic men. We evaluated the correlation between fasting glucose, prostate specific antigen and different biochemical lipid profile parameters with serum uric acid and serum creatinine in non-diabetic male between age group 40-61 years. Methods: Association between fasting serum glucose , different lipid parameters, serum uric acid, serum creatinine and prostate specific antigen in 83 non-diabetic males aged 40 to 61years were studied retrospectively. Glucose and lipid parameters and serum creatinine, serum uric acid were measured on fully automated analyser using standard reagent kits. Serum prostate specific antigen was measured by TOSOH-AIA-360, immunoassay method. Results: Correlations between different biochemical parameters were determined. Prostate specific antigen were negatively correlated with HDL (r= -0.22, p= 0.03) in age group 40-61 years. At the same fasting blood sugar were correlated positively(r= 0.34, p= 0.02 ) with prostate specific antigen in age group 51-60 years , but not in age group 40-50 years. Conclusion: We concluded that serum HDL (high density lipoprotein) was negatively associated and FBS (fasting blood sugar) was positively associated with risk of prostate cancer. We also suggest that in men of this age group a low HDL level should not be ignored while assessing prostate cancer risk especially if accompanied with an elevated FBS level even in the upper normal range.
