Hormone deprivation unnecessary with high-dose radiation, Fox Chase Cancer Center study finds

Men with prostate cancer who do not have a high risk of recurrence or disease progression do not need to have long-term hormone therapy in addition to external-beam radiation therapy if they receive high radiation doses. That is the finding of a Fox Chase Cancer Center study presented today at the 46th Annual Meeting of the American Society for Therapeutic Radiology and Oncology in Atlanta,

Findings from a study published in the September/October issue of Annals of Family Medicine suggest that low educational level should be included in coronary heart disease (CHD) treatment guidelines.

Finding that patients who have not finished high school have a 2.4 percent higher risk of dying of coronary heart disease than those with more schooling, Kevin Fiscella, M.D., M.P.H. and colleagues suggest that educational level of less that 12 years should be incorporated into the curr

Results from a University of Pittsburgh study evaluating intensity modulated radiation therapy (IMRT) for breast cancer indicate that IMRT results in a lower dose of radiation to healthy breast tissue when compared to standard radiation. The findings were presented today at the 46th Annual Meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Atlanta.

“More than 70 percent of breast cancer patients receive ionizing radiation therapy to treat their disease

Kills more cells than high-dose radiation

A new study shows that lower doses of radiation elude a damage detection “radar” in DNA and actually kill more cancer cells than high-dose radiation. With these findings, scientists believe they can design therapy to dismantle this “radar” sensor allowing more radiation to evade detection and destroy even greater numbers of cancer cells.
Researchers at the Johns Hopkins Kimmel Cancer Center tested the low-dose radiation strategy on cu

Postmenopausal women are weaker, as measured by grip and pinch tests, than women who have not entered menopause, according to a study published in the American Journal of Epidemiology. However, the researchers found that physical activity protected women from losing strength as they progress through menopause.

Researchers at Rush University Medical Center and the University of Chicago Hospitals followed a racially mixed group of 563 Chicago-area women for five years. Strength tests d

A three-year study to validate a test to detect the recurrence of bladder cancer has been initiated by the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), at 12 centers* across the United States and Canada. This test was conceived and is being conducted by NCI’s Early Detection Research Network (EDRN). By examining genetic changes in DNA obtained through urine samples, the test, if successfully validated, will provide a sensitive and non-invasive method of
