[The metastasis of prostatic cancer and the methods for its demonstration]

Metastasizing of prostate gland carcinoma is an essential and characteristic feature of its biological manifestation. The high capacity of prostate tumor cells to spread via lymphatic and blood stream explain the development of metastases in 52 to 80 per cent of patients presenting for primary diagnosis. Metastatic lesions are usually located in the lymph nodes (24.12 per cent), spinal cord (50.37 per cent), pelvis (56.27 per cent) and femur (2.09 per cent). It is impressive that according to personal experience and pertinent literature data, lymph and bone localizations vary in a wide range--29 to 66 per cent--thereby necessitating to resort to all well known diagnostic methods for demonstrating the presence of both contact and distant metastases.
