Removal of Lymph Nodes During Surgery For Thyroid Cancer May Be Beneficial

*Procedure may reduce recurrence rates, lower tumor marker levels*

Papillary thyroid cancer accounts for the majority of all thyroid malignancies, which primarily impact women. A new study indicates that routinely removing lymph nodes in the neck in these cancer patients may help prevent the disease from coming back.

When thyroid cancer metastasizes, lymph nodes in the neck may be affected, but these lymph-node tumors can be tiny and may not be detected by ultrasounds done before surgery to remove the diseased thyroid — or even during the procedure itself. (more…)

Marijuana Use Continues to Rise Among U.S. Teens, While Alcohol Use Hits Historic Lows

ANN ARBOR, Mich.— Among the more important findings from this year’s Monitoring the Future survey of U.S. secondary school students are the following:

Marijuana use among teens rose in 2011 for the fourth straight year—a sharp contrast to the considerable decline that had occurred in the preceding decade. Daily marijuana use is now at a 30-year peak level among high school seniors.
“Synthetic marijuana,” which until earlier this year was legally sold and goes by such names as “K2” and “spice,” was added to the study’s coverage in 2011; one in every nine high school seniors (11.4%) reported using that drug in the prior 12 months.
Alcohol use—and, importantly, occasions of heavy drinking—continued a long-term gradual decline among teens, reaching historically low levels in 2011.
Energy drinks are being consumed by about one third of teens, with use highest among younger teens. (more…)

Yale Scientists Identify Gene That Controls The Spread of Melanoma

Yale Cancer Center researchers have identified a gene in melanoma that can dramatically affect the spread of the disease. The study, published in the journal Cancer Cell, provides new insight into how melanoma metastasizes in patients with advanced disease, and which organs are most likely to be affected. These findings could potentially lead to new drug treatments.

Malignant melanoma is the most deadly form of skin cancer, accounting for 80 percent of all skin cancer deaths. Nearly all melanoma deaths are a result of metastasis, which can occur early in the course of tumor growth in the skin. (more…)

Understanding How Cancer Spreads: Nanotech Single-Cell Monitoring Technique Could Give Insights

ANN ARBOR, Mich.— A technique that lets researchers monitor single cancer cells in real time as they float in liquid could help doctors study the breakaway tumor cells that cause metastasis. Metastasis is the process of the disease spreading through the body. (more…)

UCLA Scientists Engineer Blood Stem Cells to Fight Melanoma

Researchers from UCLA’s cancer and stem cell centers have demonstrated for the first time that blood stem cells can be engineered to create cancer-killing T-cells that seek out and attack a human melanoma. The researchers believe the approach could be useful in about 40 percent of Caucasians with this malignancy.

Done in mouse models, the study serves as the first proof-of-principle that blood stem cells, which make every type of cell found in the blood, can be genetically altered in a living organism to create an army of melanoma-fighting T-cells, said Jerome Zack, the study’s senior author and a scientist with UCLA’s Jonsson Comprehensive Cancer Center and the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA.
