Researchers Studying Model to Learn Why Certain Cancers Become Resistant to Drugs (9/24/2007)

Resistance to chemotherapy treatments can be the worst news a cancer patient ever receives. A pair of researchers are working steadfastly to learn why some tumors eventually build a tolerance to the common chemotherapy drug cisplatin, in hopes of identifying the particular genes that can be manipulated to make treatment as effective as possible. ...> Full Article

Flu virus trots globe during off season (9/21/2007)

The influenza A virus does not lie dormant during summer but migrates globally and mixes with other viral strains before returning to the Northern Hemisphere as a genetically different virus, according to biologists who say the finding settles a key debate on what the virus does during the summer off season when it is not infecting people. ...> Full Article

Radiation Oncologists to Use Real-Time System to Help Plant 'Seeds' Against Prostate Cancer (9/21/2007)

Radiation oncologists and urologists have begun using a real-time system to implant radiation-emitting seeds in prostate cancer patients. While the system is only being used for imaging and planning purposes so far, it ultimately will help with the actual placement of the seeds. ...> Full Article

Liver Cancer Marker Could Yield Blood Test for Early Detection (9/20/2007)

In the face of an emerging liver cancer crisis in Asia, researchers at the Chinese University of Hong Kong have developed a test that could help millions. Due to widespread hepatitis B virus (HBV) infection, nearly 10 percent of China's population is at high risk for hepatocellular carcinoma (HCC), a liver cancer with low survival rates if not detected and treated early. Researchers report on a new blood screening technique that could make it possible to detect early-stage liver cancer and predict how well a patient will do following treatment. ...> Full Article

Test for Lung Cancer Looks for Discomforting Quiet among Protective Genes (9/20/2007)

When it is quiet - "almost too quiet" - in movies, it is a sign that something is about to go wrong for the good guys. This holds true for the genes that protect against lung cancer, as researchers at the University of Toledo in Toledo, Ohio, have learned. They identified a panel of 15 genes that could serve to predict cancer; if enough of their collective activity becomes quiet - almost too quiet -- it could mean they are being suppressed by other factors in the cell, a step that may lead to cancer. ...> Full Article

To Evade Chemotherapy, Some Cancer Cells Mimic Stem Cells (9/20/2007)

Anti-cancer treatments often effectively shrink the size of tumors, but some might have an opposite effect, actually expanding the small population of cancer stem cells believed to drive the disease, according to findings presented today in Atlanta, Georgia at the American Association for Cancer Research's second International Conference on Molecular Diagnostics in Cancer Therapeutic Development. ...> Full Article

Impact of New Cancer Vaccine to be Evaluated in Rochester (9/20/2007)

Rochester has been chosen as one of four national sites to monitor the effectiveness of the new cervical cancer vaccine. The project, which is funded by the national Centers for Disease Control and Prevention (CDC), will be jointly conducted by the University of Rochester Medical Center (URMC) and the New York State Department of Health. ...> Full Article

A New Technology for Cancer Screening Listens for the Signs of Cancer (9/19/2007)

Cancer-sensing devices built as cheaply and efficiently as wristwatches - using many of the same operating principles - could change the way clinicians detect, treat and monitor cancer in patients. Researchers from the Georgia Institute of Technology have created an acoustic sensor that can report the presence of small amounts of mesothelin, a molecule associated with a number of cancers including mesothelioma, as they attach to the sensor's surface. ...> Full Article

Cell death in sparrow brains may provide clues in age-related human diseases (9/19/2007)

T vs. B: Re-engineered Human T Cells Effectively Target and Kill Cancerous B Cells (9/19/2007)

Human white blood cells, engineered to recognize other malignant immune cells, could provide a novel therapy for patients with highly lethal B cell cancers such as acute lymphoblastic leukemia (ALL), according to researchers at Memorial Sloan-Kettering Cancer Center (MSKCC). By administering repeated doses of T cells designed to express an artificial receptor which recognizes human B cells, the researchers were able to eradicate cancer in 44 percent of mice bearing human ALL tumors. ...> Full Article
