Selection and delineation of target volumes in head and neck tumors: beyond ICRU definition.
Implementation of three-dimensional conformal radiotherapy (3D-CRT) and intensity modulated radiation therapy (IMRT), which permits far greater control of dose distribution, requires proper selection and delineation of target volumes, and adequate control of setup uncertainties. The present manuscript intends to review available data on selection and delineation of target volumes for primary tumor and neck nodes. Setup uncertainties and how they influence the PTV delineation are also discussed.
