Twenty-nine european centers belonging to Germany, United Kingdom, Austria, France and Italy contributed to this trial during 374 patients has been included from 1987 to 1988. This programme concerned the control of the external radiotherapy equipment available in the participating centers and the examination of the patient treatment data.
