Caudal lymphography was performed in 80 patients suffering from histologically determined carcinoma of the prostate of different degree and stages of malignancy. Metastases of the lymph nodes occur earlier and more frequently than visceral or skeletal metastases. 39% of our patients showed metastases in the lymph nodes and only 20% metastases in the skeleton. The more dedifferentiation of the tumors increases, the more frequently occur metastases in the lymph nodes. Before lymphography only 20% of the cases belonged to stage D, after it, however, the number of the patients in this unfavourable stage had doubled. Due to caudal lymphography an exact classification of stages in the carcinoma of the prostate can be achieved. It helps differentiating the curative from the palliative stages, thus influencing the therapeutic plan. Moreover, it is useful for establishing prognoses and controls of the course.
