[Fractionated afterloading irradiation as a new procedure for treating inoperable brain tumors].

A method is shown for fractionated afterloading therapy of inoperable cerebral tumors. A 3 mm thick, tube-form applicator of noble metal which is closed at the front side is implanted into the tumor by a stereotaxic technique and firmly screwed together with the osseous calotte. It remains there up to two weeks, giving full mobility to the patient. The afterloading therapy with a moving iridium source is performed one or two times per day with individual doses of 2 Gray. Thus, the chronological and--to a certain extent--also the spatial dose distribution is variable when applying this method.

[The place of ultrasonic tomography in irradiation planning (author's transl)].

Therapy-planning frequently requires cross-section sketches of the body in correct scale. The use of anatomic-topographic standard cross sections can lead to considerable errors in the estimation of the actual position of the organs and yields no information on the extension of the pathological process. The kidney, the bladder and the prostate were used as examples to demonstrate the capacity of ultrasonic tomography to supply all information, including body contour, relevant to therapy planning, as long as no limits are set to the procedure, as in the thorax area. Ultrasonic tomography can supplement but not replace the radiological procedure in therapy-planning.

[Preoperative radiotherapy of bladder cancer].

Based on the observation of 58 patients with carcinoma of the bladder the effect of preoperative irradiation is reported. After application of 3500 Rad in about four weeks the examination of the surgery preparations revealed histological absence of tumor cells in one third of the cases approximately. The irradiation technique used is described and also the effects and side-effects of synchronization induced by 5-fluorouracil in a part of the group. Consequences for the therapeutic proceeding with regard to the carcinoma of the bladder are discussed.
