[Intraoperative radiotherapy of brain gliomas].

11 patients with recurrent brain tumours underwent intraoperative radiotherapy (IORT) at a dosage of 15-25 Gy of fast electrons (17-20 MEV). IORT allows a higher dose of irradiation to be delivered to a well-defined target than is possible with external radiation, in anticipation of favourable results. However, tumour growth was not influenced in 7 out of the 11 patients and these patients died between 2 and 10 months following IORT. The remaining four patients are living still up to 15 months postoperatively. Due to the inhomogeneity of our patients no definitive conclusions can be drawn. However, well-defined tumours which can be radically excised are definitely more suitable for IORT than large, infiltrating tumours.

[Rectal shielding for a Selectron-ring applicator system (HDR- and LDR-afterloading)].

In order to decrease the morbidity rate after combined radiotherapy of the cervix carcinoma, a tungsten shield 3 and 5 mm thick for the rectum has been developed by the authors which is applied with the ring and pin applicator of the Selectron unit (LDR- and HDR-afterloading). The isodose curves were measured in a plexiglas phantom, and the radiation dose at the reference points was determined by means of a ionization dosimeter. The phantom measurements were performed with the same arrangement of sources as applied in radiotherapy. The measurements showed a dose reduction at point Rmax of 33% (HDR) and 44% (LDR) with the tungsten shield 5 mm thick.
