Although there is a concern regarding the safety of soy food consumption among breast cancer survivors, researchers have found that women in China who had breast cancer and a higher intake of soy food had an associated lower risk of death and breast cancer recurrence, according to a study in the December 9 issue of JAMA. http://www.physorg.com/news179513192.html Medicine & Health Tue, 08 Dec 2009 16:46:59 EST news179513192 (PhysOrg.com) -- A team of Northwestern University researchers, using an extremely sensitive nanotechnology-based tool known as the biobarcode system, has detected previously undetectable levels of prostate-specific antigen (PSA) in patients who have undergone radical prostatectomy. This new assay, just one of many being developed by investigators at the Nanomaterials for Cancer Diagnostics and Therapeutics Center for Cancer Nanotechnology Excellence (Northwestern CCNE), is 300 times more sensitive than commercially available PSA tests. http://www.physorg.com/news177775224.html Nanotechnology Wed, 18 Nov 2009 14:50:01 EST news177775224 A team of Northwestern University researchers, using an extremely sensitive tool based on nanotechnology, has detected previously undetectable levels of prostate-specific antigen (PSA) in patients who have undergone radical prostatectomy. http://www.physorg.com/news175188038.html Medicine & Health Mon, 19 Oct 2009 18:20:05 EST news175188038 There is concern that mastectomy is over-utilized in the United States, which raises questions about the role of surgeons and patient preference in treatment selection for breast cancer. New data from an observational study found that breast-conserving surgery was presented and provided in the majority of patients evaluated. Surgeon recommendations, patient decisions, and failure of breast-conserving surgery were all found to be contributing factors to the mastectomy rate. The findings are published in the October 14 issue of the Journal of the American Medical Association (JAMA), a theme issue on surgical care. http://www.physorg.com/news174661234.html Medicine & Health Tue, 13 Oct 2009 14:50:05 EST news174661234 A statistical model can accurately predict which patients will have poor outcomes after bladder surgery and can determine the need for chemotherapy. The analysis, to be published in the December 1, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society, concludes that the model, which considers both how far the cancer has spread and other information, such as how the cancer cells look under the microscope and the time between diagnosis and surgery, could better identify patients who need to undergo further treatment. http://www.physorg.com/news174545519.html Medicine & Health Mon, 12 Oct 2009 06:20:01 EST news174545519 A new look at a large database of prostate cancer patients shows that obesity plays no favorites when it comes to increasing the risk of recurrence after surgery: Being way overweight is equally bad for blacks and whites, say researchers at Duke University Medical Center. http://www.physorg.com/news169403980.html Medicine & Health Thu, 13 Aug 2009 18:00:03 EST news169403980 Two people with the same kind of cancer who receive the exact same treatment may nevertheless have different chances of their tumors coming back years later. Now a team of scientists has developed a computer model that predicts cancer recurrence in an individual based on how her tumor changes size in response to the first rounds of radiation therapy. http://www.physorg.com/news168016968.html Medicine & Health Tue, 28 Jul 2009 16:23:00 EST news168016968 ORLANDO, Fla.--The combination of chemotherapies 5FU and oxaliplatin compared to 5FU alone after surgery for colon cancer decreases colon cancer recurrence and promotes longer survival for patients under 70 -- but not for those who are older, according to Mayo Clinic and Dana-Farber Cancer Institute scientists who will present their findings at the American Society of Clinical Oncology's (ASCO) annual meeting in Orlando, Fla. http://www.physorg.com/news162813755.html Medicine & Health Fri, 29 May 2009 11:03:09 EST news162813755 An experimental drug derived from cottonseed shows promise in treating the recurrence of glioblastoma multiforme, widely considered the most lethal brain cancer, said researchers at the University of Alabama at Birmingham (UAB). http://www.physorg.com/news162725213.html Medicine & Health Thu, 28 May 2009 10:31:50 EST news162725213 Fox Chase Cancer Center researchers have discovered that low-oxygen regions in prostate tumors can be used to predict a rise in prostate-specific antigen (PSA) levels, a marker of tumor recurrence in prostate cancer.
