Advances in the assessment of clinically localized prostate cancer.

Objective: We review the advances in pathology, biology, and radiology which could improve the detection of extracapsular prostate cancer preoperatively.

Method: The experiences of others are compared to ours to give a topical overview of advances in the assessment of clinically localized prostate cancer.

Results: Despite new technologies, such as colour Doppler and endorectal magnetic resonance imaging, radiology does not enhance the ability to detect small invasion through the prostatic capsule.

[A clinical and endoscopic study of the treatment of benign prostatic hypertrophy using focused transrectal ultrasound].

Objective: To evaluate the clinical and endoscopic effects of transrectal focal ultrasound (Sonablate) on benign prostatic hypertrophy.

Method: This was a phase II study, performed in 13 patients with benign prostatic hypertrophy. Patients were evaluated before treatment, and 45 days and 90 days after treatment by means of a symptom score (1-PSS), uroflowmetry, estimation of prostatic volume by transrectal ultrasonography, and urethroprostatic endoscopy.

[Detection of cancer of the prostate. A study of 600 cases].

A free screening consultation for carcinoma of the prostate was proposed to men over the age of 50 years working in different companies in the areas of Paris. This consultation included a digital rectal examination, a blood test for determination of serum acid phosphatase and prostatic specific antigen, and two dimensional trans-rectal ultrasonography of the prostate. 600 patients were seen.

[Magnetic resonance imaging of cancer of the prostate. Preliminary study].

Twenty-two patients with prostatic carcinoma have been studied by magnetic resonance imaging (MRI). Twenty-three examinations have been done for 2 stage A, 11 stage B, 2 stage C and 7 stage D. Prostatic signal and locoregional extension have been compared with rectal examination and the 3 prostatectomies.
