THE EFFICIENCY OF TOMOTHERAPY HD SYSTEM ON THE TREATMENT OF DIFFERENT CANCER LOCALIZATIONS.

Helical tomography is an intensively modulated radiation therapy that has a geometry similar to that of a computed tomography. The aim of this study is to demonstrate the feasibility of the Tomotherapy HD system for the treatment of various cancer localizations: breast, rhinopharynx and prostate. There are retrospectively selected the complex cases involving positively lymph-nodes according to the histopathological results. Advantages of tomotherapy include better conformity of treatment with low doses for the organs at risk (OARs) and fewer adverse reactions comparing with 3D conformal radiotherapy (3DCRT).
