"Patients have a lower survival rate if their surgical margins are positive for tumor cells. A positive surgical margin is commonly the result of inadequate resection of the cancer's intraductal component," said Akiko Shimauchi, MD, at Tohoku University in Sendai, Miyagi, Japan. "Accurate preoperative...http://medicineworld.org/cancer/lead/9-2006/mri-best-to-detect-cancer.html Arthritis For Fatigue In Cancer Patients- February 25, 2007 Scientists here have found evidence that combining a drug typically used to treat rheumatoid arthritis with chemotherapy might help reduce fatigue and muscle wasting that often afflicts cancer patients. The findings of the preliminary study with 24 patients are published in the April 20 issue of the Journal of Clinical Oncology........http://medicineworld.org/cancer/lead/4-2006/arthritis-for-fatigue-in-cancer-patients.html Timing Of Radiation Treatments For Colon Cancer- February 25, 2007 Researchers have unexpectedly discovered that mice with the gene defect that causes colon cancer in humans can differ from normal mice in how they respond to radiation therapys. The large intestine carrying the gene defect in mice that received staggered doses of radiation was three to four times more resistant to the radiation than in control mice........http://medicineworld.org/cancer/lead/4-2006/timing-of-radiation-treatments-for-colon-cance... Fenretinide Cuts The Risk Of Second Breast Cancers- February 25, 2007 A 15-year follow-up of women in a breast cancer trial has found that fenretinide1 - a drug correlation to vitamin A - significantly cuts the risk of a second breast cancer among younger patients. The Italian research team reporting the findings on-line (Thursday 4 May) in Annals of Oncology2, are sufficiently convinced of the drug's protective potential to call for a trial to test its use as a preventive in pre-menopausal healthy women at high risk of the disease. They are now seeking...http://medicineworld.org/cancer/lead/5-2006/fenretinide-cuts-the-risk-of-second-breast-can... Detecting Oral Cancer- February 25, 2007 Scientists supported by the National Institute of Dental and Craniofacial Research, part of the National Institutes of Health, report today their initial success using a customized optical device that allows dentists to visualize in a completely new way whether a patient might have a developing oral cancer........http://medicineworld.org/cancer/lead/4-2006/detecting-oral-cancer.html Summer Sun Safety- February 25, 2007 Fifty years of medical studies show that sun exposure is a primary component in the development of melanoma, the most serious and deadly type of skin cancer, report leading dermatologists in the April 2006 issue of Dermatology Surgery. "Though genetics may play a role in the development of some melanomas, there's overwhelming evidence that shows sun exposure adversely affects patients both with and without genetic predisposition to melanoma," said Elisabeth K. Shim, M.D., an Associate Clinical..http://medicineworld.org/cancer/lead/5-2006/summer-sun-safety.html Low Dose Vitamin A Derivative Not Effective In Cancer Prevention- February 25, 2007 Taking a vitamin A derivative called isotretinoin did not reduce the risk of second primary tumors or improve survival in patients with stage I or II head and neck squamous cell cancers (HNSCC), as per a research studyin the April 5 issue of the Journal of the National Cancer Institute. In addition, current smokers had an increased risk of second primary cancers and death........http://medicineworld.org/cancer/lead/4-2006/low-dose-vitamin-a-derivative-not-effective-in... Carcinogens Found In Their Babies' Urine- February 25, 2007 When mom or dad puffs on a cigarette, their infants may inhale the resulting second-hand smoke. Now, researchers have detected cancer-causing chemicals associated with tobacco smoke in the urine of nearly half the babies of smoking parents. "The take home message is, 'Don't smoke around your kids,'" said Stephen S. Hecht, Ph.D., professor and Wallin Chair of Cancer Prevention at The Cancer Center at the University of Minnesota........http://medicineworld.org/cancer/lead/5-2006/carcinogens-found-in-their-babies-urine.html Pain Medications Prevent Cancer- February 25, 2007 Results results from a new, five-year study is showing that regular use this popular group of prescription pain relievers may reduce the risk of breast cancer by up to 71 percent. In addition, these drugs may also benefit in the prevention of prostate, colon and lung cancers........http://medicineworld.org/cancer/lead/4-2006/pain-medications-prevent-breast-cancer.html Vitamin E Offshoot A Potent Cancer Killer- February 25, 2007 Scientists here have learned how a derivative of vitamin E causes the death of cancer cells. The scientists then used that knowledge to make the agent an even more potent cancer killer. The compound, called vitamin E succinate, or alpha tocopheryl succinate, is taken by some people as a nutritional supplement, mainly for its antioxidant properties. In addition, it has a weak ability to kill cancer cells, and it has been tested as a cancer chemopreventive agent........http://medicineworld.org/cancer/lead/5-2006/a-potent-cancer-killer.html |
