DOSIMETRIC COMPARISON: INTENSITY MODULATED RADIATION THERAPY VS. 3D CONFORMAL RADIOTHERAPY IN PROSTATE CANCER RADICAL TREATMENT

Abstract

3D-Conformal Radiotherapy (3DCRT) for decades was a stand-ard technique in the prostate cancer radical radiotherapy treat-ment. Technological advances and implementation of an innova-tive radiotherapy technique-Intensity Modulated Radiation Therapy (IMRT), enable even more precise treatment of the prostate cancer patients. Intensity Modulated Radiation Therapy (IMRT) is a technological advancement in Conformal Radiotherapy which allows superior conformity and homogeneity of the absorbed dose in planning target volume with maximal sparing or-gans of risk. This technique gives us possibility to escalate the radiotherapy dose, prerequisite for the adequate local tumor con-trol. Evaluation of dosimetric parameters 3DCRT vs. IMRT: the homogeneity index, the conformity index, parameters of absorbed dose in planning target volume, dose volume constraints for or-gans of risk shows that IMRT is an optimal technique in the prostate cancer radical treatment.
