Now, physicians at Albert Einstein College of Medicine of Yeshiva University have shown that a combination of two chemotherapy drugs not only produced clinical benefit for such patients but were also well tolerated. The findings are published online in the journal Gynecologic Oncology. http://www.physorg.com/news159558309.html Medicine & Health Tue, 21 Apr 2009 18:46:14 EST news159558309 Researchers may have found a way to combine imaging with chemotherapy in a single agent for the treatment of prostate cancer, according to data presented at the American Association for Cancer Research 100th Annual Meeting 2009. http://www.physorg.com/news159546244.html Medicine & Health Tue, 21 Apr 2009 15:24:27 EST news159546244 A combination of two targeted therapies packs a powerful punch to kill pancreatic cancer cells in the laboratory, Mayo Clinic cancer researchers report.

That is the conclusion of a new study published in the May 15, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society. The study's findings indicate that efforts are needed to provide appropriate treatments for black patients and to educate them about the value of those treatments. http://www.physorg.com/news158835141.html Medicine & Health Mon, 13 Apr 2009 09:52:50 EST news158835141 Higher doses of radiation combined with chemotherapy improve survival in patients with stage III lung cancer, according to a new study by researchers at the University of Michigan Comprehensive Cancer Center. http://www.physorg.com/news158409811.html Medicine & Health Wed, 08 Apr 2009 11:44:02 EST news158409811 Researchers at North Carolina State University are looking to soy as a way to make traditional canine cancer therapy more effective, less stressful for the dog and less costly for the owners. http://www.physorg.com/news158409644.html Medicine & Health Wed, 08 Apr 2009 11:41:09 EST news158409644 Seventeen people are still dying from lung cancer each week in Northern Ireland despite a small improvement in survival rates for the disease. http://www.physorg.com/news157954027.html Medicine & Health Fri, 03 Apr 2009 05:07:30 EST news157954027 A novel hemodialysis procedure helps restore kidney function and increases lifespan in patients with multiple myeloma, according to a study appearing in the April 2009 issue of the Clinical Journal of the American Society Nephrology (CJASN). http://www.physorg.com/news157826284.html Medicine & Health Wed, 01 Apr 2009 17:38:39 EST news157826284 New research from UC Davis Cancer Center shows that a protein called Muc4 may be the essential ingredient that allows breast cancer to spread to other organs and resist therapeutic treatment.
