Proton Therapy Has Better Outcome over IMRT for Advanced Head and Neck Cancers

Radiation oncologists compared the world’s literature on outcomes of proton beam therapy in the treatment of a range of advanced head and neck cancers of the skull base compared to intensity-modulated radiation therapy and found that proton beam therapy significantly improved disease-free survival and tumor control when compared to IMRT.

Four Imaging Approaches Can Differentiate Malignant and Benign Breast Tumors

Imaging breast tumors using four approaches together, can better distinguish malignant breast tumors from those that are benign, compared with imaging using fewer approaches, and this may help avoid repeat breast biopsies.   More...

NMR-Based Diabetes Risk Index Helps to Identify Normal-Weight Individuals at High Risk of Progressing to Type 2 Diabetes

A nuclear magnetic resonance-based diabetes risk index is being used to identify normal-weight individuals at high risk of progressing to type 2 diabetes, and may enable a more comprehensive risk assessment and intervention in at-risk patients.  More...

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).

Proton Therapy Provides Safe, Long-Term Treatment for Hodgkin Lymphoma

In spite of various successes in treating patients with Hodgkin lymphoma, many patients suffer from the late effects of radiation therapy and chemotherapy treatment, including the possible onset of breast cancer or heart disease.   More...
