Diagnostic methods in the detection of prostate cancer: a study of a randomly selected population of 2,400 men.

We investigated the value of digital rectal examination, transrectal ultrasonography and prostatic specific antigen (PSA) analysis as aids in general clinical practice and in the early detection of prostate cancer. Of a randomly selected population of 2,400 men 55 to 70 years old who were offered examination with digital rectal examination, transrectal ultrasound and PSA analysis, 1,782 (74%) accepted and prostate cancer was detected in 65 (3.6%).

Modal DNA values and estramustine-binding protein (EMBP) as prognostic markers in prostatic cancer.

In this study, we have investigated the model DNA values and the expression of estramustine-binding protein (EMBP) in formalin-fixed and paraffin-embedded TUR specimens from 76 untreated patients with prostatic cancer. In addition, specimens from 13 patients were analyzed for tumour EMBP expression only. Ploidy was measured as diploid, tetraploid and non-tetraploid aneuploid or aneuploid in the near-diploid region.

Digital rectal examination versus transrectal ultrasound in detection of prostate cancer. Preliminary results from a study of a randomly selected population.

In a study of 2,400 randomly selected men (age 55-70 years) for early detection of prostate cancer the authors have compared the diagnostic value of digital rectal examination (DRE), transrectal ultrasound (TRUS) and prostate specific antigen (PSA). Altogether 62 prostate cancers were detected, corresponding to a detection rate of 3.5% but by use of DRE the detection rate was only 2.

Expression of estramustine-binding protein (EMBP) and the proliferation-associated antigen Ki-67 in prostatic carcinomas.

The expression of EMBP and the proliferation-associated antigen Ki-67 was studied in in vitro cultured prostatic carcinoma cells and in tumor tissues removed by transurethral electroresection (TUR). EMBP was found to be expressed predominantly in the moderately differentiated carcinomas. A technique based on the immunohistochemical analysis of fine needle specimens was also evaluated.
