Other investigators have expanded the C-DVH to include functional and spatial information [ 4 34 35 ] , but the current investigation is the first report correlating a DVH which has been expanded to include BED parameters with late treatment toxicity for prostate cancer irradiation .
The authors are aware of the recent efforts regarding advanced modeling concepts for evaluating the relationship between physical irradiation and biological damage on normal structures - in particular, BED provides a measure of biological effect at a point at which it is calculated - measuring the absolute biological effect over a volume having a non-uniform dose distribution formally requires the computation of the equivalent uniform dose (EUD) [ 23 ] . However, this caveat does not apply directly to the current task, because the goal of the current investigation is to use the DVH (constructed using either conventional dose or BED) as a relative measure of biological response, not as an absolute measure, and in this context constructing a DVH from BED computations and averaging the DVH's (both C-DVH's and BED-DVH's) over a patient population was felt to be an appropriate methodology.
First, there is an inherent loss of spatial information with the construction of a DVH plot.
As expected, the DVH's (both C-DVH's and BED-DVH's) were predictive of rectal and urinary toxicity - that is, those that developed late GI or GU toxicity had DVH's that demonstrated more integral dose to the rectum or bladder than those patients who did not develop such toxicity.
Second, the dose plotted on the x-axis of a conventional DVH (C-DVH) is conventional dose, which does not take into account many factors influencing the effects of the dose on the given tissue.
