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.

Shaped-beam radiation therapy is a promising treatment for life-threatening metastatic liver tumors

...according to researchers at the University of Rochester Medical Center who report an 88 percent success rate for controlling the lesions. This is the first evidence that doctors can treat these tumors with radiation, and the results doubled the average length of survival.

Patients with head and neck cancer may be spared the risk and expense of surgery by undergoing a CT scan

Researchers with the UF Shands Cancer Center have identified criteria doctors can use to evaluate CT scans four weeks after patients undergo initial treatment. If these criteria are met, there is a 94 percent likelihood a patient's lymph nodes are cancer free, said Stanley L. Liauw, M.D., a resident in radiation oncology.

Intensity modulated radiation therapy (IMRT) for head and neck cancer

Results from a University of Pittsburgh study evaluating intensity modulated radiation therapy (IMRT) for head and neck cancer determined the ideal doses for lessening treatment side effects. The findings were presented today at the 47th Annual Meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Denver.

Treating malignant melanoma of the uvea with radiation therapy can spare patients from significant vision loss

Treating a rare form of eye cancer with radiation therapy can spare patients from significant vision loss, according to new research at Wake Forest University Baptist Medical Center.

Possible new combination treatment regimen for patients with head and neck cancers who develop a second tumor

Few treatment options exist for patients with head and neck cancers who develop a second tumor or whose disease recurs in an area that has previously received radiation. Data from an international study reveal a possible new combination treatment regimen that offers a significant survival advantage for many of these patients.

Treating four or more brain tumors in a single radiosurgery session resulted in improved survival

...compared to whole brain radiation therapy alone, according to a study the University of Pittsburgh School of Medicine presented today at the 47th Annual Meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Denver.

Single men are less likely to seek radiation re-treatment for pain caused by prostate cancer

"Patients often experience a great deal of pain if their cancer spreads to the bone," explained Andre Konski, M.D., M.B.A., M.A., F.A.C.R., director of clinical research in the radiation oncology department at Fox Chase Cancer Center and lead author of the paper on the Radiation Therapy Oncology Group study (RTOG 97-14).

Study shows possibilities for curing patients with early-stage Hodgkin's lymphoma of their cancer

Doctors in Germany have determined that patients suffering from early-stage Hodgkin's lymphoma can receive a reduced dose of involved field radiation therapy, combined with chemotherapy, and still retain a high survival rate, according to a study presented October 17, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

Researchers identify biomarker that indicates a more agressive form of prostate cancer

Staging factors for prostate cancer such as PSA and the Gleason score are extremely useful in predicting prostate cancer outcome," explained Pollack. "However, new biomarkers hold promise in strengthening our ability to predict response to treatment. By identifying the more virulent forms of prostate cancer, we may be able to tailor treatment or develop therapies to target the abnormalities identified."

Treating breast cancer with "MammoSite" study

Treating breast cancer with MammoSite resulted in a low risk of complications and was generally well tolerated, according to a University of Pittsburgh School of Medicine study presented today at the 47th annual meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Denver.

Breast magnetic resonance imaging helps doctors select best treatment for early breast cancers

Breast magnetic resonance imaging enhances patient selection for accelerated, partial breast irradiation by detecting previously unsuspected, microscopic lesions within the breast, according to a study presented October 17, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

Accelerated partial breast irradiation using balloon brachytherapy is an excellent option for women with early breast tumors

A new method of radiation -- accelerated partial breast irradiation using balloon brachytherapy -- makes it more convenient for breast cancer patients to receive radiation therapy after surgery and appears to be safe, offer good cosmetic results, and keep cancer from coming back, according to four-year results of an ongoing study presented October 17, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

Course of radiation after prostate cancer surgery improves cancer-free survival rates

Patients with advanced stage prostate cancer who receive radiation therapy immediately after surgery to remove their prostate live longer without their cancer returning than patients who do not receive radiation after surgery, according to a study presented October 17, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

17 Oct 2005

Radiation therapy combined with hormone therapy after surgery is more effective in keeping the breast cancer from returning

The current standard of care for early-stage breast cancer is breast conserving surgery (lumpectomy) to remove the tumor followed by radiation and hormone therapy to kill any remaining cells.

Radiation therapy combined with chemotherapy before surgery helps patients beat rectal cancer

For patients with rectal cancer, receiving radiation therapy and chemotherapy before surgery to shrink the tumor so it can be more easily removed helps keep the cancer from coming back, according to a study presented October 17, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

17 Oct 2005

Breast conserving surgery followed by radiation therapy is a good option for women with early-stage breast cancer who have breast implants

The new findings challenge past studies that showed delivering radiation to a breast with an implant in place causes significant problems in the implant, resulting in poor cosmetic results.

New radiation technique to treat cancer that has spread to the brain prevents hair loss

Patients whose cancer has spread to the brain can avoid typical hair loss (alopecia) when treated with newer radiation techniques, thereby improving their quality of life while still controlling their cancer, according to a study presented October 16, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

Gene therapy may prevent the damaging effects of radiation

Gene therapy could be used as an agent to protect normal tissues, including the esophagus and lung, from damage during a second administration of radiation therapy for non-small cell lung cancer, according to an animal study presented by University of Pittsburgh researchers at the 47th Annual Meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Denver.
