An Evaluation Of Methods To Reduce Inframammary Surface Dose In Prone Breast Irradiation, Seth Alvarado

Culminating Experience Projects

In cases of breast radiation treatments via external beam radiation therapy, the incidence of radiation dermatitis has been reported. In prior studies, this acute radiation side-effect has been correlated with the immobilization devices in cases of prone breast irradiation. They attribute this to the bolus effect that occurs with the interaction of the incident photon beam at different projections causing an increase in measured surface dose. The type of radiation planning technique, and patient positioning during the undertaking of these techniques, have also shown to influence this bolus effect. This study focuses on these factors in treatment planning in order …

A Comparison Between Rectal Dose In Prostate Radiotherapy Patients Treated With Spaceoar Hydrogel Present Versus Patients Treated Without Spaceoar Hydrogel., David Desano

Culminating Experience Projects

Introduction: External beam radiation therapy is a common treatment option for prostate cancer patients with localized disease. Radiation-induced side effects associated with the rectum can impact a patient’s ability to complete treatment or affect the quality of life years after radiation treatment. Spaceoar hydrogel has been developed to reduce radiation dose to nearby pelvis structures, and therefore decreasing potential side effects.

Methods: A total of 20 patients who received definitive radiation therapy to the prostate and seminal vesicles were selected and placed into 2 groups (10 spaceoar, 10 non-spaceoar). The individuals’ age ranged from 60 to 79 years old with …
