Gross tumor volume

Fig. 1. This example of a cumulative dose volume histogram (DVH) exemplifies the manner in which three dimensional treatment planning allows the radiation oncologist to ensure that the tumor receives the planned dose while limiting the dose of radiation received by the normal structures. In this example 100% of the gross tumor volume (GTV) receives 70 Gy whereas the dose received by any length of the spinal cord is less than 45 Gy. Fig. 1.

Figure 16 Proton therapy for uveal melanoma. Dose distribution obtained with a beam of 60-MeV protons with an appropriate spread-out Bragg peak (energy modulated from 14-60 MeV). Transverse section through the center of the eye. The position of the tumor [gross tumor volume (GTV)] is indicated by the posterior hatched area. Protons allow to obtain a homogeneous dose over the whole GTV with effective sparing of the normal structures. This implies a great precision in patient-beam positioning.

The impact of PET for gross tumor volume (GTV) delineation will be discussed based on three examples amino acids-PET in brain gliomas, fluorine-18-labeled glucose analog fluorodeoxyglucose (FDG)-PET in lung cancer, and FDG-PET in head and neck tumors. [Pg.154]
