Prostate Specific Antigen (PSA) has emerged as the most applicable and important tumor marker for carcinoma prostate. In the present study PSA was determined in serum of healthy subjects, patients of benign prostate hypertrophy (BPH) and Carcinoma Prostate (Ca−P) to evaluate its diagnostic efficiency in day to day management of prostate cancer patients and in differentiating patients of early prostate cancer from those with BPH. Receiver operating characteristic curve (ROC) revealed 2 ng/ml and 10 ng/ml cut off serum PSA level for BPH and untreated carcinoma prostate patients (Ca−P). An extremely significant increase (P<0.0001) was observed in mean PSA concentration in BPH patients and adenocarcinoma prostate patients when compared to healthy males. Clinical relevance of PSA was highlighted by a case study of cancer patient prior to any therapy till death. [ABSTRACT FROM AUTHOR]

Zinc (Zn), copper (Cu), magnesium (Mg) and retinol levels were studied in serum and tissue of the patients with prostatic carcinoma (Ca), benign hyperplasia (BHP) and control subjects. Zinc and retinol levels were low in both serum and tissues of patients with carcinoma, while in BHP, both zinc and retinol level were decreased. Copper levels were high in serum and tissues of both BHP as well as carcinoma patients. Magnesium levels were elevated in both serum and tissues of cancerous patients. The results indicate that Zn, Cu, and Mg metabolism is disturbed in malignancy. [ABSTRACT FROM AUTHOR]
