SOME CHARACTERISTICS OF AGE, ULTRASOUND AND THE RELATION BETWEEN THE PSA DENSITY AND THE HISTOPATHOLOGY OF BENIGN NODULAR PROSTATIC HYPERPLASIA AND PROSTATIC CARCINOMA

Abstract

Background: PSA density by the ratio of tPSA/prostatic volume plays a meaningful role for the orientation of diagnosis and the screening of the prostatic diseases, especially for the prostatic carcinoma and benign nodular hyperplasia. Objectives: - To describe some characteristics of the age, ultrasound of the patient with the prostatic carcinoma and benign nodular hyperplasia; - To determine the relation between PSA density and the histopathology of the patient with the prostatic carcinoma and benign nodular hyperplasia. Materials and Method: cross-sectional study on 70 patients including 35 cases with benign nodular prostatic hyperplasia and 35 ones with carcinoma of the prostate. Results: The average age was the same between 2 groups of the diseases, 73 for prostatic carcinoma and 75 for benign nodular hyperplasia. 100% of the lesions was discovered by ultrasound, the average weight of the carcinoma and benign nodular hyperplasia was 57.3g and 46.9g respectively. The tPSA density was higher in carcinoma than in benign nodular hyperplasia (1.22 vs 0.10); With the tPSA density threshold >0.15, the prostatic carcinoma accounting for 78.4%, then the benign group only 21.6%; the Sensitivity and the Specificity were 82.9% and 77.1% respectively. Conclusions: PSA density should be applied for the diagnosis and the screening of the prostatic tumors beside the tPSA test. Key words: tPSA (total PSA), PSA density, ultrasound, prostatic carcinoma, benign nodular prostatic hyperplasia.
