مقارنة بين تقنيات مختلفة لعلاج سرطان الثدي باستخدام العلاج الإشعاعي المطابق (3D-CRT)

Abstract

In this research, the radiation dose distribution of different techniques used in the treatment of breast tumors, namely single treatment center  and  two treatment center ,  and  with the application of half and complete beams to the chest wall and clavicle area, were evaluated. The number of Monitor Units (MU) was calculated, Dose Volume Histograms (DVHS) were given, analyzed, and quality indicators were calculated for comparison between techniques. The dose of healthy organs adjacent to the tumor was also calculated and the doses of Dmin, Dmean and Dmax were compared for each treatment plan. In addition to using the Wilcoxon test to calculate the p-value statistic, and display the results of all planned target sizes  in the form: (Average ± standard deviation), mean value and statistical value P-value that highlight the fundamental difference between the techniques. The results showed that  reduces the number of MUs , analysis of volume dose curves for ,  ,  and  shows that  Intervention for maximum dose Dmax and minimum dose Dmin,  and  without high dose in the contact area, and there is no significant difference between the techniques for the dose of OAR Organs At Risk. The results of  show a more homogeneous dose distribution within the planned area of the tumor, and also the dose coverage prescribed for the planned target is better than in other techniques, so we can use  In radiation therapy planning systems for breast tumors with a high degree of reliability.
