title: The comparison between vitamin d concentration in upper silesia patients with prostate cancer and with benign prostatic hyperplasia.
abstract: A number of studies have shown that vitamin D has a protective effect against the development of cancer, which may also be related to prostate cancer. Low serum vitamin D concentration has also been demonstrated in benign prostate hyperplasia. We compared serum vitamin D concentration in two groups of Polish men with prostate cancer and benign prostate hyperplasia. Each group comprised 30 patients. The concentration was determined by ELISA. To assess the difference between the study population, non-parametric Mann Whitney U test was used. The results revealed that patients with prostate cancer are deficient in vitamin D (median =25.3, quartiles q1 - q3: 13.4 -33.4). The concentration of vitamin D in the group of patients with prostate cancer was lower than in the group of benign prostatic hyperplasia with vitamin D deficiency (median =34.8, quartiles q1 - q3: 17.9  44.3). Vitamin D concentration in Polish men with prostate cancer is lower compared to patients with benign prostatic hyperplasia.
