title: [Diagnostic and prognostic value of quantitative monitoring of prostate specific antigen in blood serum and urine from patients with prostate cancer after radical prostatectomy].
abstract: OBJECTIVE
  To study values of prostate-specific antigen (PSA) in the blood serum and urine before and after massage of the prostatic bed in patients with prostatic cancer (PC) after radical prostatectomy.
  
  
  METHODS
  Changes in serum and urine PSA concentrations were followed up in 17 patients with PC (T2-3N0M0) 14 months (4-24 mon) after radical prostatectomy. Control examinations were made once a month. MRT or CT and osteoscintigraphy were made in suspected recurrence and/or metastases of PC.
  
  
  RESULTS
  There were no changes in PSA consentrations in the serum and urine before and after the massage of prostatic bed in 10 of 17 patients. In 3 patients PSA concentrations in blood and serum increased after the massage, in one of them blood levels of PSA after the massage went up 5 months after PSA increase in the urine. In 4 of 17 patients urine PSA levels increased after the massage, the blood levels remaining the same.
  
  
  CONCLUSIONS
  Follow-up measurements of blood and urinary levels in PC patients after radical prostatectomy before and following massage of the prostatic bed allow detection of prostatic PSA-positive cells which were not removed at surgery. We suggest that these cells may be the basis of recurrent disease.
