title: [Diagnosis and evaluation of the extent of cancer of the prostate].
abstract: Diagnosis is suggested by the functional symptoms and digital rectal examination and must be confirmed by histological examination. The second step is to evaluate the patient's condition, the extent of the cancer and the consequences on the urinary system; the choice of the treatment depends on this evaluation. The most common tumors are adenocarcinomas with a histological grading strongly correlated to the lymphatic involvement and frequency of metastases. Lymphatic involvement is closely related to the local clinically demonstrable involvement, histological grade, serum acid phosphatase concentrations and results of lymphography. Upon diagnosis of cancer of the prostate more than half the patients already harbour metastases, usually of the bone. This percentage is correlated to the size of the primary tumor, involvement of the seminal vesicles, histological grade and lymphatic involvement. The authors propose a series of investigations adapted to each case.
