【 摘 要 】

3D - Conformal Radiotherapy (3DCRT) for decades was a standard technique in the prostate cancer radical radiotherapy treatment. Technological advances and implementation of an innovative 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 organs of risk. This technique gives us possibility to escalate the radiotherapy dose, prerequisite for the adequate local tumor control. 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 organs of risk shows that IMRT is an optimal technique in the prostate cancer radical treatment.
