[Radiological check-up examinations for the assessment of therapeutic response in malignant bone diseases].

Results of the improved treatment in radiation therapy of malignant bone lesions demand regular check-up examinations in order to assess the therapeutic response. For this purpose roentgenographic verifications are recommended before the beginning of treatment and after finishing radiation therapy and furthermore two or three months later. Follow-up by radionuclide scanning is suggested. An initially possible increase of a bone lesion in the course of radiotherapeutic treatment does not justify to stop radiation therapy.
