A new study has found that beta radiation treatment can prevent repeat blockages in heart vessels following angioplasty. The treatment was tested on patients who underwent balloon angioplasty for coronary artery disease and showed a significant reduction in recurrent blockage rates.
Scientists at the University of Rochester Medical Center are exploring the use of genetic algorithms to treat prostate cancer by improving how radiation is delivered. The formulas have been developed by medical physicist Yan Yu, Ph.D., who heads a task force on the subject for the American Association of Physicists in Medicine.
The Comprehensive Cancer Center at Cedars-Sinai has begun treating patients with a next-generation radiation therapy system that allows physicians to deliver precise, three-dimensional radiation treatments. This technology enables the delivery of full doses of radiation to tumors while protecting surrounding normal tissues.
Researchers have discovered a new drug, pifithrin-alpha, that can protect healthy tissues from radiation damage and reduce side effects. The treatment strategy may allow for higher doses of therapy to be administered, improving cure rates.
Xie George Xu's 3D virtual man, VIP-Man, simulates radiation's effect on the skin, lens of the eye, optic nerve, and bone marrow with high accuracy. The model will enable accurate treatment planning for diseases requiring radiation therapy, revolutionizing radiation dosimetry in biomedical sciences and engineering.

Researchers at Thomas Jefferson University have found that radiation therapy helps patients with localized prostate cancer live longer. After examining the results of 1560 patients who received radiation therapy alone for prostate cancer, they discovered that those with high-risk disease benefited the most from higher doses of radiation.
A USC study suggests that radiation therapy is not necessary for DCIS patients with margin widths of 10mm or more, and may even be counterproductive due to side effects and costs. Patients with narrower margins may benefit from postoperative radiation therapy.
A combination of radiation and chemotherapy treatment significantly increased overall survival in esophageal cancer patients, with 22% surviving at least eight years after treatment. The study found that this combined therapy was associated with longer survival compared to radiation therapy alone.
