New radiation technique helps brain cancer patients keep their hair
October 17, 2005Patients 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.
Most brain cancer patients whose cancer has spread to the brain receive whole brain radiotherapy. This treatment uses two simple radiation beams on each side of the head to target the cancer. It also causes patients to lose the hair on their head. Since hair loss can be upsetting for patients, doctors are experimenting with new types of radiation therapy to see if they are as effective in treating the cancer while preventing hair loss.
In this study, researchers enrolled 10 patients with stage IV cancer that had spread to the brain. Doctors were able to improve upon whole brain radiation therapy by using intensity modulated radiation therapy. This technique, called IMRT, allowed them to further control the intensity of each beam and shape them to better target the cancer while sparing nearby healthy tissue (including hair follicles), allowing patients to significantly reduce the amount of hair they lost.
Half of the patients in the study reported only slightly noticeable hair loss four weeks after treatment ended, and half had no noticeable hair loss. Patients also didn't experience some of the side effects of whole brain radiation, such as a rash on the scalp or behind the ears. With a short follow-up period, overall survival is 100 percent and only one patient has seen their cancer progress.
"This new study will encourage doctors to consider using this new radiation technique to treat cancer that has spread to the brain," said Todd Scarbrough, M.D., lead author of the study and a radiation oncologist at the MIMA Cancer Center in Melbourne, Florida. "Although hair loss may seem trivial, losing one's hair can be difficult for a patient who is already depressed from the diagnosis and the strain of the treatments. I'm hopeful this new study will help us improve the quality of life for these patients."

Visualizing atomic-scale acoustic wavesin nanostructures
Acoustic waves play many everyday roles - from communication between people to ultrasound imaging. Now the highest frequency acoustic waves in materials, with nearly atomic-scale wavelengths, promise to be useful probes of nanostructures such as LED lights.
PET scans track small tumors after stereotactic body radiotherapy
Readily available CT screening for lung cancer is increasing the discovery of small, primary lung cancers. For many, a radiation technique called stereotactic body radiotherapy presents a less invasive treatment option to surgery that is typically offered to non-surgical candidates.
Lymphedema risk greatly increased with boost of radiation to axillary nodes
The significant risk of developing lymphedema may outweigh the benefit of receiving an extra boost of radiation to lymph nodes possibly involved in early-stage breast cancer.
New radiation technique can greatly reduce painful skin burns in women with breast cancer
Breast cancer patients who undergo a new radiation technique called intensity modulated radiation therapy (IMRT) after surgery are three times less likely to have severe skin reactions from the treatment compared to standard radiation therapy.
New technique in permanent bradytherapy for the treatment of lung cancer
The University Hospital at Navarre University has developed a system for the percutaneous implantation of palladium 103 seeds, a new technique in permanent bradytherapy for the treatment of lung cancer. Recently, the fourth experiment was carried out and the results remitted to the scientific magazine, "Bradytherapy", for its publication. To date there has been no description in world scientific literature of any case using this therapeutic procedure. The Cl'nica Universitaria has hosted the only cases of bradytherapy using palladium implantation although, in the literature, there exist two articles on the treatment of 8 patients with iodine 125, a radioisotope especially suited to treatmen

![1961 Cold War Nuclear Fallout Propaganda Movie by the American Government [DVD]: Civil Defense, Radiation Sickness, Radioactive Poisoning & Fallout Shelter Footage](http://ecx.images-amazon.com/images/I/41hxCDROosL._SL160_.jpg) |
1961 Cold War Nuclear Fallout Propaganda Movie by the American Government [DVD]: Civil Defense, Radiation Sickness, Radioactive Poisoning & Fallout Shelter Footage This 1961 U.S. Civil Defense film is significant because it was among the first of its kind to characterize nuclear fallout as dangerous. Making the claim that every U.S. citizen lives within fallout range of a "likely nuclear attack target," the film uses maps and various shots of highways, suburbs, crowds, and pedestrians to show the potential for fallout to affect everyone. The use of dramatic music and narration suggests that this was a typical "scare film" meant to induce the public to take the threat of nuclear fallout seriously. There is even footage of a man dying in a hospital bed, presumably of radiation sickness. Various methods for surviving nuclear war for humans and even livestock are shown. Not a cheery Cold War propaganda relic, this film about the dangers and effects of... |
