Psa prostate test accuracy
The score for carcinoma in the hypoechoic areas was 6. The importance of systematic map biopsy is emphasized. Pathology Oncology Research Vol 6, No 2, Introduction Materials and Methods The ultrasound-directed systematic prostate biopsy, which creates a real "map" of the prostate, was introduced more than 10 years ago and is now considered the most effective diagnostic tool to detect prostate carcinoma.
Furthermore, systematic map-biopsy of the prostate promotes the distinction between clinically significant and so-called "infraclinical" prostate carcinomas indicating therapeutical consequences. Altogether patients were map-biopsied, 77 of them were positive by rectal digital examination RDE and 25 were negative.
The age of RDE positive patients was The serum PSA level was The normal values of PSA by this method are 0.
Hypoechoic zones were detected using a 7. Nine needle biopsies were taken regularly, first in transversel, then in longitudinal section from both lobes, according to the method described by Resnick! Formalin-fixed, paraffin embedded blocks were made and 8 11m sections were stained psa prostate test accuracy haematoxylin and eosin HE. Only 5 samples taken from the 23 hypoechoic zones proved to be CA 6.
Megfertőzhető-e egy lány prosztatagyulladással? Anesthesia: General. Findings: The patient had extensive involvement of the bladder with solid and edematous-appearing hemorrhagic tumor completely replacing the trigone and extending into the bladder neck and prostatic tissue. The ureteral orifices were not identifiable. Postoperative radiotherapy adjuvant radiotherapy is controversial because not all patients with adverse pathological findings will have tumor recurrence.
Out of these, in 43 cases the CA was diagnosed from biopsies taken from other parts of the prostate than the hypoechoic zones and in 5 cases both the hypoechoic zones and other parts of the prostate contained CA. Altogether 29 RDE positive cases proved to be Table 1. None of these zones contained CA, according to the result of biopsy.
These 4 cases can be considered as false negative, regarding RDE see Table 2. Table 3 shows the number of samples of systematic biopsies in which CA could be detected.

It is noteworthy, that in 10 cases only 1 sample was CA positive. After establishing the diagnosis of prostate carcinoma, total prostatectomy was performed in 22 cases and hormonal therapy was induced in 30 cases.
Discussion The classical method for detection of prostate carcinoma, rectal digital examination is still the most important diagnostic tool,l1 which helps to apply more sophisticated techniques, such as ultrasound and ultrasound directed core biopsy.
The relatively low diagnostic score led to the development of ultrasound directed systematic "map" biopsy of the prostate. From the opposite point of view, Table 4.
We may also confirm the data previously reported 7,8,15,16 that hypoechoic area biopsy alone is insufficient for diagnosis of prostate carcinoma. In accordance with the literature6,9,14,16 the proportion of cases with hypoechoic areas was lower among RDE negative than in RDE positive patients.

None of these areas contained carcinoma in our material, however with systematic biopsy four carcinomas could be detected in our RDE negative patients, which confirms the importance of elevated serum PSA levels even in RDE negative casesy,18 Our results provided further data on the diagnostic value psa prostate test accuracy systematic prostate map biopsy and may facilitate the selection of patients for total prostatectomy.

Tumor volume is used, along with the Gleason Score, to prognosticate prostate cancer recurrence. PSA density helps distinguish between BPH and prostate cancer and determine the need for prostate biopsy.
