Background: During the 3rd Symposium on "Experimental Radiotherapy and Clinical Radiobiology" (Hamburg, March 1994) the consequences of the recent events in the Department of Radiotherapy of the University-Hospital in Hamburg for daily radiotherapy practice in Germany were discussed. The following topics were covered: information of the patient, choice of therapy, development of new treatment modalities, ethics committee, follow-up and role of radiobiology.
Discussion and results: Information of the patient: Due to the insecure juridical situation in Germany there is a tendency to inform patients excessively, which is rather confusing for them. Adequate information of patients is a difficult task for physicians considering their daily workload. Choice of therapy: Unfortunately in Germany radiotherapists are often not initially involved in planning of the overall treatment strategy for individual cancer patients. The recent events in Hamburg led to a decreased referral of cancer patients for radiotherapy. This might even hold for tumor entities where radiotherapy is an essential part of therapy. Another problem is that dose might be reduced inadequately. This would reduce complications but also significantly increase local failure. Development of new treatment modalities: There are no special juridical problems with the conduction of clinical studies for optimization of radiation treatments. Ethics committee: Ethics committees are not only meant to safeguard patients but also protect physicians and institutions from the consequences of questionable research.
Follow-up: Only radio-oncologists are adequately trained for follow-up after radiation treatment. Nevertheless, because of administrative, financial, legal and political problems many patients in Germany are not regularly seen by the radiation oncologist after end of radiation treatment. Always when new treatment strategies are established, careful follow-up is of special concern. Role of radiobiology: The main obligation of clinical radiobiology is to introduce radiobiological knowledge into clinical practice. This may be best promoted by a period of radiobiological research during residency. However, close collaboration between radiotherapists and radiobiologists is only possible at very few centres in Germany, because the institutes of radiobiology are dismantled systemically.
