Abstract

This study aims to demonstrate the conformity and homogeneity level achieved by 3D conformal radiation therapy for head and neck malignant tumors patients. Conformity and homogeneity indices are good quantitative tools for assessing and comparing the dose conformity and homogeneity of various treatment plans of one patient. In this study fifteen patients with advanced head and neck tumors have been selected. For each patient, five plans were promoted by using four planning techniques which were, Field-in-Field (FIF), Bellinzona, Conpas, Forward-PlannedMultisegments (FPMS) with multiple energies denoted as FPMS (M) and another identical plan of FPMS but with using single energy denoted as FPMS (S). The CIRTOG recorded values of 1.46±0.16, 1.47±0.16, 1.52±0.18, 1.564±0.20, 1.58±0.21 for FPMS (M), FPMS (S), FIF, Conpas, and Bellinzona respectively. The HI recorded values of 0.187± 0.014,0.193±0.011, 0.196±0.031, 0.202±0.017, 0.219±0.02 for FPMS (S), FPMS (M), FIF, Bellinzona, and Conpas respectively. It has been observed from the results that FPMS technique either using multiple energies or single has the highest conformity and homogeneity followed by FIF technique. For conformity, Conpas has the third rank followed by Bellinzona technique. For homogeneity, Bellinzona has the third rank followed by Conpas technique.
