BOSTON, Mass. (September 14, 2009) -- In a one-two punch, a familiar diabetes drug reduced tumors faster and prolonged remission in mice longer than chemotherapy alone, apparently by targeting cancer stem cells, report Harvard Medical School researchers in the Sept. 14 advance online Cancer Research.
A new study finds that there is little information available about the use of new testing technologies and targeted therapies in breast cancer, specifically the anti-cancer drug trastuzumab (Herceptin).
ANN ARBOR, Mich.---The growth of cancerous tumors is fueled, at least in part, by the buildup of free radicals---highly reactive oxygen-containing molecules.
NEW YORK -- A new type of stem cell discovered in the prostate of adult mice can be a source of prostate cancer, according to a new study by researchers at the Herbert Irving Comprehensive Cancer Center at Columbia University Medical Center and NewYork-Presbyterian Hospital.
HOUSTON ― Active, but non-invasive breast cancer is set free to roam as invasive breast cancer when an overexpressed protein converts it to a different cell type, scientists at The University of Texas M. D. Anderson Cancer Center report in the Sept. 9 issue of the journal Cancer Cell.
A new study identifies a molecule that acts cooperatively with a well known oncoprotein to drive progression of noninvasive breast cancer to metastatic, life-threatening disease.
PHILADELPHIA -- Use of the molecularly targeted agent lapatinib to delay tumor growth and improve the survival of patients with inoperable hepatocellular carcinoma, or liver cancer, only benefited certain subgroups of patients.
PHILADELPHIA -- Immune responses are capable of killing tumors before they can be directed toward normal body tissue, according to new scientific findings published in Cancer Research, a journal of the American Association for Cancer Research.
JACKSONVILLE, Fla. -- Scientists at the Mayo Clinic campus in Florida have found that the lung cancer oncogene PKCiota is necessary for the proliferation of lung cancer stem cells. These stem cells are rare and powerful master cells that manufacture the other cells that make up lung tumors and are resistant to chemotherapy treatment.
(SALT LAKE CITY) -- In a finding with potentially major implications for identifying a viral cause of prostate cancer, researchers at the University of Utah and Columbia University medical schools have reported that a type of virus known to cause leukemia and sarcomas in animals has been found for the first time in malignant human prostate cancer cells.
A molecular signature that helps account for the aggressive behavior of a variety of cancers such as pancreatic, breast and melanoma may also predict the likelihood of successful treatment with a particular anti-cancer drug.
DURHAM, N.C. -- One person's breast cancer is not the same as another person's, because the gene mutations differ in each tumor. That makes it difficult to match the best therapy with the individual patient.
JACKSONVILLE, Fla. -- In a biological rendition of fiction's Strange Case of Dr. Jekyll and Mr. Hyde, researchers from the Mayo Clinic campus in Florida and Harvard Medical School have found that a protein thought to protect against cancer development can actually spur the spread of tumors.
The targeted therapy Avastin, alone and in combination with the chemotherapy drug CPT-11, significantly increased response rates, progression-free survival times and survival rates in patients with a deadly form of brain cancer that had recurred.
