To assess the importance of using SBRT-LATTICE-PATHY for the radiotherapy treatment of large tumors that would be considered intractable by currently used standard techniques. In this present study, the investigators will have the possibility of combining SBRT and LATTICE techniques, incorporating the concept of hypoxic tissue irradiation, which are potential modulators of abscopal and bystander effects, performing partial punctual treatment in the vertex region, without the need for irradiation of the entire tissue volume, further improving safety in relation to possible toxicities.
