ESTRO-Varian Clinical Research Awards 1992
The first prize of the Varian Clinical Research Awards 1992 was awarded during the ESTRO 11 Congress in Maim0 to Dr. G. Leunens of the Department of Radiotherapy of the University of Leuven, Belgium, for her report on "The monitoring of quality of the treatment process in a radiotherapy department by in vivo dosimetry". It was a hard task for the jury (H. Bartelink, J. C. Horiot, H. Sack and E. van der Schueren) to arrive at their decision since the quality of other competing projects was very high. A few years ago it was thought by many that in-vivo dosimetry had a limited future in monitoring routine treatments delivered to patients. However, the development of quality assurance gave a strong incentive to revise this statement. The work of Dr. Leunens with semi-conductor detectors was addressed to patients treated for head and neck cancers. The transmission and Target Absorbed Dose could be calculated from entrance and exit dose measurements and allowed not only the estimation of the global accuracy of the dose delivery in a department, but also the evaluation of the accuracy of dose delivery in specific treatment situations and at the individual patient level. It also showed that the inhomogeneity of the dose actually delivered to the target volume was much larger than predicted from the dose computation. In summary, this work brings new evidence: that it is now possible by in-vivo dosimetry to assess the accuracy of treatment delivery checking the entire radiation therapeutic process by a single procedure. This work is a milestone and provides the basis for a new generation of actions in quality assurance which are of primary importance since they provide the missing link represented by the immediate verification of the individual treatment. The second prize was awarded to Dr. S. J. Whitaker from the Royal Marsden Hospital, London, U.K., for "The quantification of ionizing radiation induced DNA double-strand breaks in polymine depleted ceils". The third prize was awarded to Dr. N. G. Burnet from the Institute of Cancer Research, Sutton, U.K. for his work on "The relationship between cellular radiation sensitivity and tissue response to radiotherapy may provide the basis for individualising radiotherapy schedules".
