Infection-Fighting Cancer Treatment Could Boost Leukemia Risk
Compounds called growth factors, given to help cancer patients better tolerate chemotherapy and reduce infection, may actually boost their risk for leukemia or a bone marrow disorder later on, new research suggests. Even so, the researchers said the findings are not cause for alarm.

Childhood Cancer Survivors Face Increased Sarcoma Risk
Survivors of pediatric cancer face nine times the normal risk for developing a sarcoma at least five years after treatment for the initial cancer, a new study reveals. The risk for developing sarcoma -- a cancer of the connective or supportive tissue -- is particularly elevated among patients with a family history of cancer or whose primary childhood bout was a form of sarcoma, a bone tumor or Hodgkin lymphoma, the researchers found.

Cancer Genome Scientists Discover 100 More Mutated Genes
Cancer is a disease of genes gone awry, but new insights into the "cancer genome" could point the way to effective treatments, an international team of researchers reports. Scientists taking part in the Cancer Genome Project say they've identified more than 100 mutated genes that help drive 210 different cancer types.

Study Compares Stem Cell Transplants for Myeloma
Younger patients diagnosed with the blood cancer myeloma survived longer if they received a stem cell transplant from themselves that was followed by one from a matched sibling -- rather than receiving two transplants from themselves, researchers report. However, while the protocol may be a good treatment alternative for some patients, they represent only a fraction of the total who develop myeloma, outside experts said.

Childhood Leukemia Survivors at Long-Term Risk of Second Cancer
The longest such study of its kind has found that people who survive acute lymphoblastic leukemia (ALL) in childhood are at higher risk of developing a secondary cancer well into middle-age. The risk for these tumors only increases over time, the 30-year study found.

Gene Insights Could Boost Blood Supply
A new discovery by Australian scientists could greatly extend the shelf life of donated blood. The team says they've gained a greater understanding of the internal clock in blood components called platelets, potentially paving the way toward ways to keep them alive longer.

First U.S. Online Autism Registry Begins
Experts say they've launched the first U.S. national online autism registry. The Interactive Autism Network (IAN), which began on Monday, will link parents of children with autism with researchers in an effort to learn more about the causes, treatments and possible cures for autism.

Health Highlights: April 12, 2007
People who took the drug Gleevec (imatinib mesylate) after having a particular type of gastrointestinal tumor removed were significantly less likely to have the cancer recur than people who didn't take the drug, the U.S. National Institutes of Health said Thursday in announcing results of a new study

Daily Aspirin May Reduce Cancer Risk
A daily aspirin may lower the odds of colon, prostate and breast cancer for people at high risk for those malignancies, researchers at the American Cancer Society report. Men and women who used adult-strength aspirin daily for five or more years had about a 15 percent lower overall rate of developing cancer, particularly colon, prostate and possibly breast cancer," said study lead author Eric Jacobs, an epidemiologist at the ACS.

Studies Assess Risk of Developing Primary, Secondary Cancers
The risk of developing primary or secondary cancer is dependent on the interaction of genetics, personal habits and environmental exposure, new research suggests. The studies were expected to be presented Monday at the annual meeting of the American Association for Cancer Research, in Los Angeles.

Health Highlights: May 1, 2007
The U.S. Food and Drug Administration warned Tuesday that 24 apparently related Web sites that appear on pharmacycall365.com may be involved in the distribution of counterfeit drugs. In recent months, the FDA has received reports that counterfeit versions of the weight-loss drug Xenical were obtained from consumers from two different Web sites. Further investigation revealed that the two Web sites (brandpills.com and pillspharm.com) involved in these incidents are among 24 that appear on the pharmacycall365.com home page under the "Our Websites" heading.

Gene Discovery May Improve Pancreatic Cancer Diagnosis, Treatment
Scientists say they can use small bits of genetic material called microRNA to spot key differences between chronic pancreatitis and pancreatic cancer, aiding in earlier diagnosis for the lethal malignancy. The researchers say doctors might also someday use microRNA to help predict the survival of patients with pancreatic cancer.

Hepatitis C Infection Ups Lymphoma Risk
People with the liver disease hepatitis C face a higher risk of developing lymphoma, a cancer of the immune system, new research suggests. Overall, the risk is almost 30 percent higher, but for a certain type of lymphoma called Waldenstrom's macroglobulinemia, the risk is almost 300 percent higher, according to the study.
