Researchers have identified a pivotal protein in a cellular transformation that makes a cancer cell more resistant to treatment and more capable of growing and spreading, making it an inviting new target for drug development. http://medicalxpress.com/news/2013-02-protein-central-cancer-stem-cell.html Cancer Wed, 13 Feb 2013 14:30:01 EST news279987024 Researchers at the University of California, San Diego School of Medicine have discovered that hard-to-reach, drug-resistant leukemia stem cells (LSCs) that overexpress multiple pro-survival protein forms are sensitive – and thus vulnerable – to a novel cancer stem cell-targeting drug currently under development. http://medicalxpress.com/news/2013-01-drug-hard-to-reach-leukemia-stem-cells.html Cancer Thu, 17 Jan 2013 12:00:18 EST news277642727 A new targeted drug demonstrated its ability to control metastatic gastrointestinal stromal tumor, an uncommon and life-threatening form of sarcoma, after the disease had become resistant to all existing therapies, report investigators at Dana-Farber Cancer Institute who led the worldwide clinical trial. http://medicalxpress.com/news/2012-11-drug-resistance-patients-rare-sarcoma.html Cancer Wed, 21 Nov 2012 18:30:09 EST news272740107 (HealthDay) -- Long-term medication side effects such as fatigue can be key for patients deciding which cancer drug to take, new research suggests. http://medicalxpress.com/news/2012-06-long-term-side-effects-key-cancer.html Cancer Sat, 02 Jun 2012 14:00:01 EST news257862311 Treatment with three relatively new "targeted" cancer drugs has been linked to a slightly elevated chance of fatal side effects, according to a new analysis led by scientists at Dana-Farber Cancer Institute. They added that the risk remains low, but should be taken into account by physicians and patients. http://medicalxpress.com/news/2012-02-cancer-drugs-fatal-side-effects.html Cancer Mon, 06 Feb 2012 16:00:20 EST news247755859 Cancer treatments designed to block the growth of blood vessels were found to increase the number of cancer stem cells in breast tumors in mice, suggesting a possible explanation for why these drugs don't lead to longer survival, according to a new study by researchers at the University of Michigan Comprehensive Cancer Center. http://medicalxpress.com/news/2012-01-avastin-sutent-breast-cancer-stem.html Cancer Wed, 25 Jan 2012 09:31:17 EST news246706261
