Serum Prostatic Antigen Measurement in Localized Prostatic Cancer: Correlation with Clinical Course

Abstract

Serial serum prostatic antigen measurements were performed on patients treated for localized prostatic carcinoma. There was good correlation of mean serum prostatic antigen levels and the surgical stage of the disease. Among patients treated by radical prostatectomy there was good correlation of an elevated serum prostatic antigen and the development of metastatic disease. It appears that serum prostatic antigen is a good indicator and predictor of the development of distant metastasis in this group of patients.
