[Individual fixation during irradiation following breast-conserving surgery. Methodology and clinical results in 50 patients].

From February, 1986 through October, 1987, fifty patients with mammary carcinomas of the stages T1N0M0, T2N0M0, T1N1M0 and T2N1M0 were irradiated after breast-preserving surgery. The irradiation conditions were standardized with cobalt-60 gamma radiation or photons emitted by a linear accelerator and fixed oblique position in a specially manufactured, individual rigid foam bed. The position was checked every week at the therapy simulator with an analog tomographic attachment. The method, positioning in a 30 degrees oblique position and immobilization in an individually moulded rigid foam bed is described, and the necessity of regular tomographic controls in treatment position is underlined. Because of the short follow-up time of eight months, clinical results can only be presented with regard to early side effects and cosmetic results. A final assessment of this method is therefore not yet possible.
