PET/CT planning beneficial for head and neck cancer patients
Using a combination of positron emission tomography (PET) and computed tomography for radiation therapy treatment planning in head and neck carcinoma patients provides for excellent, local and regional disease control when compared to CT alone. view more (2008-03-05)
Brain stem cells sensitive to space radiation
Cold Spring Harbor Laboratory (CSHL) scientists recently led a team of researchers to study potential effects of space radiation on astronauts. view more (2007-12-12)
Majority of Ordering Physicians Lack Knowledge of Radiation Exposure Risks from CT
Ordering physicians have limited knowledge of CT-related radiation exposure and its associated risks, according to a study performed at the Carilion Clinic in Roanoke, VA. view more (2009-04-24)
Men with prostate cancer avoid radiation due to misconceptions
Negative perceptions about radiation therapy can strongly influence a prostate cancer patient's choice to avoid external beam radiation therapy, even though studies have proven the treatment to be as safe and effective as other treatments for the disease, including surgery. view more (2006-11-06)
Study shows optimal dose management of warfarin improves anticoagulation control
Researchers from Boston University School of Medicine (BUSM) have determined the optimal dose-management strategy to derive maximal benefit from warfarin therapy and improve patient outcomes. Results of the study appear online in the December 2008 issue of the Journal of Thrombosis and Haemostasis. view more (2008-12-23)
A new radiation therapy treatment developed for head and neck cancer patients
Most head-and-neck cancers that recur locally after prior full-dose conventional radiation therapy respond to Boron Neutron Capture Therapy (BNCT). view more (2007-08-17)
Combination therapy shows improvement for breast cancer patients
Giving radiation therapy and chemotherapy at the same time after a lumpectomy helps keep breast cancer from returning locally. view more (2006-12-01)
Tackling the threat of nuclear terrorism
The only effective way to tackle the threat of nuclear terrorism is to abolish nuclear weapons and establish strict international control of all fissile materials that could be used to make new weapons, argue three US physicians in this week's BMJ. In the aftermath of 11 September 2001, nuclear terrorism has emerged as a real threat and could... view more... (2002-02-06)
Researchers discover atomic bomb effect results in adult-onset thyroid cancer
Radiation from the atomic bomb blasts in Hiroshima and Nagasaki, Japan, in 1945, likely rearranged chromosomes in some survivors who later developed papillary thyroid cancer as adults, according to Japanese researchers. view more (2008-08-29)
Normal tissue not spared in new forms of breast cancer radiotherapy
A five day course of radiotherapy to treat breast cancer may, in some cases, expose as much lung and heart tissue to potentially toxic radiation as does the standard six weeks of treatment, say researchers at Mayo Clinic Jacksonville. view more (2007-10-31)
Combination therapy reduces tumor resistance to radiation
Radiation is used to treat a variety of tumors and the response of tumors to radiation is dependent on endothelial cell death, which in turn limits oxygen delivery to the tumor, causing hypoxia and tumor cell death. view more (2007-06-08)
Largest PSA bounce study eases worry of prostate cancer returning
Prostate cancer patients who have a temporary rise in their prostate specific antigen (PSA) levels after radiation therapy-called a PSA bounce-are not at an increased risk of their cancer coming back any more than those who don't have a temporary rise. view more (2006-11-09)
New Treatment for Radiotherapy-Induced Side Effects Developed at Oxford
As seen in recent health news reports, treatments for side effects associated with radiotherapy are in high demand. An Oxford University scientist at the Research Institute of Oxford’s Churchill Hospital has invented a new non-toxic compound therapy that has shown positive results in the treatment of radiotherapy-induced side effects. This... view more... (2002-10-09)
OHSU Cancer Institute researchers study breathing during radiation
Oregon Health & Science University researchers have determined exactly how much breathing affects prostate movement during radiation treatment. view more (2008-09-24)
COMMONLY PRESCRIBED ANTIBIOTIC INEFFECTIVE FOR TREATING BRONCHITIS (p 1648)
A US study in this week's issue of THE LANCET concludes that the antibiotic azithromycin is ineffective for treating bronchitis, even though it is often prescribed by physicians for this condition. Azithromycin is an expensive, broad-spectrum antibiotic; there is limited evidence about its effectiveness in treating bronchitis. Arthur Evans and... view more... (2002-05-08)
Needle-size device created to track tumors, radiation dose
Engineers at Purdue University are creating a wireless device designed to be injected into tumors to tell doctors the precise dose of radiation received and locate the exact position of tumors during treatment. view more (2008-04-09)
Informational handout key to giving parents a better understanding of CT radiation risks
Simply giving parents informational handouts can improve their understanding of the potential increased risk of cancer related to pediatric CT, according to a recent study conducted by researchers from The Children's Hospital in Denver, CO and Yale University School of Medicine in New Haven, CT. view more (2007-08-15)
New treatment option breaks Leukemia's resistance to chemotherapy, radiation therapy
German researchers set out to outwit cancer tumor cells that have become resistant to chemotherapy or radiation therapy and ended up expanding therapeutic applications of radionuclides in fighting leukemia. view more (2006-06-05)
Growing food crops on radioactive soil?
Scientists at Horticulture Research International have been studying natural mutations in vegetables in the hope of identifying the genes responsible for limiting uptake of caesium. The results of their quest, to be presented at the annual SEB conference suggest 'safe' crops could one day be grown on radioactive soil. Four million people in... view more... (2003-03-31)
Experimental agents may prevent radiation-induced leukemia
Treatment with biphosphonates could prevent radiation-induced leukemia, according to data presented at the American Association for Cancer Research 100th Annual Meeting 2009. view more (2009-04-20)
