A new study is taking a closer look at the benefits versus risks for lung cancer patients to undergo preventative brain radiation therapy as a means to stop cancer from spreading to the brain. Study results show that while preventative brain radiation for patients with non-small cell lung cancer "“ the most common form of lung cancer "“ does reduce the chance of developing brain metastases, it impacts some short-term and long-term memory. The study also reveals that preventative...

Fox Chase Cancer Center researchers report that radiation therapy alone can reduce prostate specific antigen (PSA) levels below detectable amounts in prostate cancer patients. Patients who have an undetectable level of PSA after therapy have less chance of biochemical failure than other patients and a good chance of being cured. The data was presented today at the annual meeting of the American Society for Radiation Oncology. "With high quality radiation"“"“whether it is from an...

After mastectomy, breast cancer patients who receive radiation treatment to the lymph nodes located behind the breast bone do not live longer than those who do not receive radiation to this hard-to-treat area, according to a randomized 10-year study presented at the plenary session, November 2, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO). Breast cancer that is located in an internal, central location in the breast area, and larger tumors that have...

Patients with non-small cell lung cancer treated with preventative brain radiation (called prophylactic cranial irradiation or PCI), significantly decrease their risk of developing brain metastases (cancer spread in the brain) by more than 50 percent (from 18 percent to 8 percent), compared to those who did not receive the treatment, according to a randomized study presented at the plenary session November 2, 2009, at the 51st Annual Meeting of American Society for Radiation Oncology...

High-risk melanoma patients who are treated with radiation after surgery have a significantly lower risk of their cancer returning to the lymph nodes (19 percent), compared to those patients who do not have radiation therapy (31 percent), according to the first randomized study of its kind presented at the plenary session, November 2, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO). "Results of this trial now confirm the place of radiation therapy in...

Moderately to severely obese prostate cancer patients may have improved treatment outcomes when treated with image-guided radiation therapy (IGRT) over traditional external beam radiation therapy (EBRT) because IGRT corrects for prostate shifts, which, if not planned for, can lead to incorrect doses of radiation to the disease site, according to a study in the September 1 issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for...
