Multicenter Study
Lung irradiation for Ewing's sarcoma with pulmonary metastases at diagnosis: results of the CESS-studies.
In the German CESS-studies, Ewing's sarcoma patients with pulmonary metastases at diagnosis were considered as candidates for additional bilateral lung irradiation. We have retrospectively analyzed the impact of radiotherapy on survival. ⋯ In this retrospective analysis, lung irradiation was beneficial in terms of improved survival of patients with pulmonary metastases of Ewing's sarcoma. We actually recommend lung irradiation with 18 (to 20) Gy for pulmonary metastases of Ewing's sarcoma.

Multicenter Study Clinical Trial
[Radiotherapeutic quality assurance in the Hodgkin's disease study HD4 supported by the BMFT (Bundesministerium für Forschung und Technologie)].
In the German Hodgkin Study Group a radiotherapy assurance program is being carried out at the radiotherapeutic reference centre in Göttingen since April 1988: 74 patients were entered from 27 radiotherapeutic institutions. 18 of them participated in a quality assurance program and submitted the data of 29 patients: In 21 of the 29 patients the protocol was followed correctly. Physical aspects of quality control showed two major deviations from the protocol: one center used photon energies of more than 15 MVX without mould; another had a anterior-posterior loading of 3:1. The radiation oncology assessment detected six inadequate treatments: The safety margin was inappropriate in three of 26 mantle fields. Another center used a multiple field technique, and in two patients the paraaortic region was not irradiated.
