The new radiotherapy techniques as HDR and LDR brachytherapy, stereotactic radiotherapy, 3D-CRT, and IMRT require an accurate knowledge of the biological characteristics of the tumor with correct definition of target volumes. As demonstrated by the two reported cases, the formulae equivalent to 2 Gy in the special techniques are useful for the increase in the total dose to GTV while sparing the organs at risk.
