[On the individualized, combined therapy of Ewing's sarcoma (author's transl)].

With eleven patients, for whom in the period 1967-74 a diagnosis of Ewing's sarcoma was confirmed, it was shown how by intensifying the chemo- and radiotherapy the survival time of some patients could be prolonged. At the same time surgical therapy has become less important. The diagnostical difficulties of the histomorphological differentiation of Ewing's sarcoma from lymphosarcoma are detailed on the example of another patient. A further general intensification of the chemo- and radiotherapy is not possible as the organism's limit of acute tolerance is already reached. Any future improvement on the results of treatment seems therefore only possible if combination therapy is modified to correspond to the particular needs of the individual patient.
