Target definition and dose prescription in the era of dose painting and probabilistic planning
The concepts of GTV, CTV and PTV form the backbone of describing a treatment in present-day radiation oncology. While powerful, these concepts are not quite suitable to describe probabilistic nature of our knowledge of tumor location and dose requirements. In probabilistic planning, the PTV concept is circumvented by including uncertainties upfront. Currently however, a standardized method is lacking for describing the uncertainties that need to be considered. In this symposium the speakers will discuss these uncertainties and a possible generalization of the current GTV, CTV and PTV concepts to accommodate a probabilistic approach to delineation and dose prescription.
