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%).

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.

Conventional heparin and semisynthetic heparin analogue (SSHA) alteration of blood coagulation after embolic occlusion of human renal circulation.

Blood coagulation and fibrinolytic variables were measured in a peripheral vein in a study of 21 consecutive patients before and after angio-embolization of renal carcinoma. The first ten patients received conventional heparin, 5000 IU twice daily, and the following eleven a semi-synthetic heparin analogue (SSHA), 50 mg twice daily, for 5 days. The first injection was given 2 hours before embolization and the last injection at least 12 hours before the last blood sampling.

Blood coagulation alterations after embolic occlusion of the renal circulation.

Alterations in blood coagulation and fibrinolysis after embolic occlusion of renal adenocarcinoma were investigated in 11 patients. Peripheral vein blood was collected before, 2 hours after and on the first, third and fifth to seventh day after embolization. Five patients had renal vein blood sampling before and 2 hours after embolization.
