External radiation therapy treatment with electron boost for the chest wall is the treatment protocol for breast cancer after mastectomy with positive axillary lymph nodes. followed by a local electron boost to the local lymph nodes with a total dose of 10 Gy. Outstanding locoregional control was shown in the majority of patients treated with this strategy, with a 3-year survival rate of 90% and a 5-year survival rate of 87%, and a 3-year survival rate of 61% and a 5-year survival rate of 47% without distant metastases.
Purpose and Objective(s): The study's objective is to compare the computed monitor units with RadCal software dosimetry in order to evaluate the monitor unit of electron cutout boost for treatments of the chest wall following the external beam radiation therapy.
Material/Methods: 15 patients with mastectomy, aged range from 35 to 75 years. They all went for a single electron boost field with dose of 10 Gy using 12 MeV beam. Then the delivered dose MU were compared with RadCal software dosimetry.
Results: The result showed no statistically significant difference between the MU measured with electron filed and the calculated MU with the RadCalc software dosimetry. The excellent result outcome achieved with electron cutout with comparison with the RadCal and found to be statistically significant (P = 0.025).
Conclusions: The result showed a assess the monitor unit of electron cutout for treatments in chest wall irradiation after mastectomy boost in external beam radiation therapy in comparison with the calculated monitor units with RadCalc software dosimetry.
