Research methodology and new radiotherapy technology.
In the last 25 years there were major dramatic advances in radiotherapy technology with the improvement in treatment quality and a stimulus to clinical research in an era of rigorous control of information in oncology. In radiation oncology, research methodology has aimed at the application in clinical practice of the information provided by basic research, always considering the related ethical principles. A number of trials based on boosting techniques with dose-escalation are in progress and an improved long-term survival is expected; however a prospective analysis of unexpected late side-effects is required. Some personal recommendations for clinical researchers involved in new radiotherapy technology are suggested.
