Resumo(s)
Radiotherapy is one of the therapeutics selected for localized prostate cancer, in cases where the tumour is confined to the
prostate, penetrates the prostatic capsule or has reached the seminal vesicles (T1 to T3 stages). The radiation therapy can be
administered through various modalities, being historically used the 3D conformal radiotherapy (3DCRT). Other modality of radiation administration is the intensity modulated radiotherapy (IMRT), that allows an increase of the total dose through modulation of the treatment beams, enabling a reduction in toxicity. One way to
administer IMRT is through helical tomotherapy (TH). With this study we intent to analyze the advantages of helical
tomotherapy when compared with 3DCRT, by evaluating the doses in the organs at risk (OAR) and planning target volumes (PTV).
