Image: An axial CT scan slice through the heart (red) of a patient with Hodgkin lymphoma involving the mediastinum. On the left is the X-ray plan and on the right is the proton plan. The dark blue line in both represents the tumor and target area for the radiation. The green line represents the volume of the body receiving 95% of the total prescribed dose of radiation, while the light blue line reflects the volume of the body receiving 10% of the total prescribed radiation dose. As is apparent, with conventional radiation (left), the X-rays deposit more radiation in the heart and breasts than the proton plan. In fact, the proton plan reduced the mean dose to the heart by more than 50% and the mean dose to the breast by 70%. For this reason, it’s believed that Hodgkin lymphoma patients will have a much lower risk of heart disease and second malignancy with proton therapy than what’s been observed in the past with conventional radiation therapy (Photo courtesy of the University of Florida Proton Therapy Institute).
