Short-term Hormone Therapy Added to Radiation Increases Survival for Medium-risk, but Not Low-risk, Prostate Cancer Patients
Short-term hormone therapy given prior to and during radiation treatment to medium-risk prostate cancer patients increases their chance of living longer, compared to those who receive radiation alone, however there is no significant benefit for low-risk patients, according to the largest 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). (Embargoed until 02-Nov-2009, 09:00 ET)

Additional, Specialized Radiation Not Necessary for Some Women After Mastectomy
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). (Embargoed until 02-Nov-2009, 09:00 ET)

Radiation After Surgery Reduces Chance of Melanoma Returning
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). (Embargoed until 02-Nov-2009, 09:00 ET)

What Are the Real Benefits Versus Risks of Preventative Brain Radiation for Patients with Non-small Cell Lung Cancer?
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 (ASTRO). (Embargoed until 02-Nov-2009, 09:00 ET)

Stereotactic Radiotherapy Stops Lung Cancer from Growing in Frail Patients
Stereotactic body radiation therapy (SBRT) stopped the growth of cancer at its original site in the lung for three years among nearly 98 percent of patients with early non-small cell lung cancer (NSCLC) who are unable to have the cancer surgically removed, according to an updated three-year study presented November 2, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO). (Embargoed until 02-Nov-2009, 12:00 ET)

Obesity Significantly Increases Side Effects of Stereotactic Body Radiation Therapy in Lung Cancer Patients
Obesity, not the amount of radiation given, is the greatest factor in whether early-stage lung cancer patients develop chest wall pain after receiving stereotactic body radiation therapy to the chest wall, with obese patients being more than twice as likely to develop chronic pain compared to those who have less body weight, according to a first-of-its-kind study presented Tuesday, November 3, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO). (Embargoed until 02-Nov-2009, 13:00 ET)

Adding Proton Therapy “Boost” to X-ray Radiation Therapy Reduces Prostate Cancer Recurrences
Men who receive a “boost” of proton therapy after receiving a standard course of X-ray radiation therapy have fewer recurrences of their prostate cancer compared to men who did not receive the extra dose of proton radiation, according to a first-of-its-kind study presented November 2, 2009, at the American Society for Radiation Oncology’s 51st Annual Meeting in Chicago. The multi-institutional, randomized trial also shows that the high dose treatment is safe for these patients and causes no severe problems later with urinary or bowel functions. (Embargoed until 02-Nov-2009, 12:20 ET)

Proton Therapy Is Well-tolerated in Prostate Cancer Patients
Proton beam therapy can be safely delivered to men with prostate cancer and has minimal urinary and rectal side effects, according to a study presented November 2, 2009, at the American Society for Radiation Oncology’s 51st Annual Meeting in Chicago. (Embargoed until 02-Nov-2009, 12:30 ET)

Shorter Radiation Course Stops Cancer Growth in High-risk Prostate Cancer Patients
Hypofractionated radiation treatment, a newer type of radiation treatment that delivers higher doses of radiation in fewer treatments than conventional radiation therapy, is significantly more effective in stopping cancer from growing in high risk patients, compared to receiving standard radiation treatment, according to a study presented November 4, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO). In addition, findings show there is no increased risk of negative side effects later in patients who undergo hypofractionated radiation. (Embargoed until 03-Nov-2009, 13:00 ET)
51st ASTRO Annual Meeting, November 1-5, 2009
—American Society for Radiation Oncology (ASTRO)

Shorter Radiation Course as Effective as Standard Therapy for Prostate Cancer Recurrence
A shorter, five-week course of radiation treatment that delivers higher doses of radiation in fewer sessions, known as hypofractionation, appears to be just as effective and as safe in reducing the risk of prostate cancer from returning as standard radiation therapy, yet is delivered in two-and-a-half weeks less time, according to interim results of a randomized study presented November 4, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO). (Embargoed until 03-Nov-2009, 13:00 ET)

Three-week Course of Breast Radiation May be as Effective as Conventional Five to Seven Week Course for Early Breast Cancers
According to a study presented November 4, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO), a shortened, more intensive course of radiation given to the whole breast, along with an extra dose of radiation given to the surgical bed of the tumor (concomitant boost), has been shown to result in excellent local control at a median follow up of two years after treatment with no significant sides effects. (Embargoed until 04-Nov-2009, 12:30 ET)

Cancer Patients Want Honesty, Compassion from Their Oncologist
What do patients want from their radiation oncologists? The most significant preference is that more than one-third of female cancer patients (37 percent) prefer to have their hands held by their radiation oncologists during important office visits, compared to 12 percent of men, according to a randomized study presented November 4, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO).

Stereotactic Radiosurgery as Effective in Eliminating Parkinson’s Disease Tremors as Other Treatments, but Less Invasive
Stereotactic radiosurgery (SRS) offers a less invasive way to eliminate tremors caused by Parkinson’s disease and essential tremor than deep brain stimulation (DBS) and radiofrequency (RF) treatments, and is as effective, according to a long-term study presented November 2, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO).
