Radiation Therapy News and Research

RSS

Radiation therapy (also called radiotherapy, x-ray therapy, or irradiation) is the use of a certain type of energy (called ionizing radiation) to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated (the “target tissue”) by damaging their genetic material, making it impossible for these cells to continue to grow and divide. Although radiation damages both cancer cells and normal cells, most normal cells can recover from the effects of radiation and function properly. The goal of radiation therapy is to damage as many cancer cells as possible, while limiting harm to nearby healthy tissue.

Using a light hand to treat Hodgkin disease

Children with low-risk Hodgkin disease can be cured using cancer drugs that have only minimal or no toxicity, combined with low doses of radiation, according to St. Jude researchers.

Survivors of childhood cancers have a ninefold increased risk of developing a secondary sarcoma

Treatments for childhood cancer have resulted in a current overall cure rate of over 70 percent. However, long-term survivors of childhood cancer are at a higher risk of developing a secondary cancer than the general population.

HIV protein TAT used to pull protein Bim into cancer cells - helps kill cancer cells

Cancer cells are sick, but they keep growing because they don't react to internal signals urging them to die. Now researchers at Washington University School of Medicine in St. Louis have found an efficient way to get a messenger into cancer cells that forces them to respond to death signals. And they did it using one of the most sinister pathogens around - HIV.

Seed implants critical for achieving a better prostate cancer outcome

More than ninety percent of men who receive appropriate radiation dose levels with permanent radiation seed implants to treat their prostate cancer are cured of their cancer eight years after diagnosis, according to a study released in the February 1 issue of the International Journal for Radiation Oncology - Biology - Physics, the official journal of ASTRO.

Cetuximab may prolong survival for head and neck cancer patients

Preliminary findings show adding the chemotherapy drug cetuximab (brand name Erbitux) to radiation therapy and chemotherapy may help some patients with head and neck cancer live longer, according to a study presented at the plenary session of the Multidisciplinary Head and Neck Cancer Symposium, co-sponsored by the American Society for Therapeutic Radiology and Oncology, the American Society for Clinical Oncology and the American Head and Neck Society.

Cetuximab with radiotherapy does not increase side effects for head and neck cancer patients

The addition of Cetuximab (brand name Erbitux) to radiation therapy treatments does not increase the rate or duration of some side effects in the treatment of advanced head and neck cancers, according to a study presented at the plenary session today at the Multidisciplinary Head and Neck Cancer Symposium, co-sponsored by the American Society for Therapeutic Radiology and Oncology, the American Society for Clinical Oncology and the American Head and Neck Society.

Piolitazone shows promise for preventing brain injury from radiation therapy

Researchers at Wake Forest University School of Medicine are the first to report that in animal studies, a common diabetes drug prevents the memory and learning problems that cancer patients often experience after whole-brain radiation treatments.

DNA methylation and breast cancer

A new study using mastectomy tissue shows that precancerous changes can occur in normal-appearing areas of the breast as distant as two inches from a tumor's edge.

Enzyme PMR1 reveals kind side

New research shows that a recently discovered enzyme that destroys the messenger RNA (mRNA) for some proteins can also help to protect the mRNA during times of stress. The response might help cancer cells survive chemotherapy and radiation therapy.
