Taking the Side Effects Out of Chemotherapy - Fumagillin, a fungal toxin, recently has been seen as an effective cancer treatment in combination with other anticancer drugs. However, human trials have shown fumagillin to have neurotoxic side effects at the high doses required by standard methods. In their work, the researchers coated nanoscopic beads (500 times smaller than the width of a human hair) of an inert oily compound used in artificial blood with doses of fumagillin that were 1,000 times less than what typically is used. The amount appeared to be as effective as the conventional dosage, but with no adverse effects on lab animals.

Activating Protein to Kill Tumor Cells -
University of Michigan researchers have designed a small molecule, called MI-219, that activates a certain protein to kill tumor cells. Protein p53, which normally helps suppress tumors, is inactivate in almost all human cancers. Traditional cancer drugs also activate p53 but they do so by causing DNA damage. They kill not only tumor cells, but also normal cells, resulting in severe side effects. The molecule targets only cancer growth.

Diamonds Deliver -
Researchers from Northwestern University have shown that nanodiamonds are an ideal vehicle for delivering a chemotherapy drug without harm to healthy cells. To make the material effective, the researchers manipulated single nanodiamonds, each only two nanometers in diameter (a blood cell is about 7.5 nanometers), to form aggregated clusters of nanodiamonds, ranging from 50 to 100 nanometers in diameter. The drug, loaded onto the surface of the individual diamonds, is not active when the nanodiamonds are aggregated; it only becomes active when the cluster reaches its target.
For their study, the researchers used living murine (type of small rodent) macrophage cells (cells that contribute to the immune system), human colorectal carcinoma cells, and the chemotherapy drug doxorubicin hydrochloride. The drug was loaded onto the nanodiamond clusters, which carried the drug inside the cells. Once inside, the clusters broke up and slowly released the drug.

Detecting Cancer in Saliva - Only about half of the 30,000 people in the United States diagnosed with oral cancer will survive five years, because this type of cancer is often detected at a late stage and spreads quickly. But researchers at the University of California, Los Angeles, have developed the first standardized saliva test that can diagnose oral cancer long before telltale lesions appear. The test detects oral cancer by scanning a sample for certain "messenger RNA" (mRNA) molecules that can indicate a developing tumor. The test is 85% accurate (the widely used blood test has about the same accuracy) and results come back in 24 hours. The test was based on breakthrough work in oral cancer that helped researchers prove that there is RNA associated with diseases in saliva. The researchers are looking to simplify the test for home use and standard dentist office equipment. Source:
"Listening in" on Cancer - Researchers at the University of California, Riverside, are developing nanodevices that can "listen" to the subtle cues that cancerous cells emit. The research is based in part on microelectrical arrays, thin metal plates about the size of a human hair in diameter that are used to sense the electrical activity from different types of cells. The technique allows scientists to differentiate cells from various parts of the body as well as cancerous cells from healthy ones. The researchers also are developing drug-delivery systems based on nanotubes in conjunction with the microelectrical array devices. They already have identified electrical activity differences in certain cells and have created a library of different signature patterns. The objective of the research is to replace the standard practice of injecting what often are toxic dyes into cells to find out which ones are cancerous. The project is part of the National Cancer Institute's $144.3 million five-year initiative to incorporate nanotechnology in cancer research. Sources: www.physorg.com/news7980.html
Highlights of Cancer Facts & Figures 2007
Here are some of the highlights from the American Cancer Society's Cancer Facts & Figures 2007:
In 2007, 1,444,920 new cancer cases and 559,650 deaths, or about 1,500 deaths per day, from cancer are expected in the United States.
Among men, cancers of the prostate, lung and bronchus, and colon and rectum account for more than half (54 percent) of all newly diagnosed cancers. Prostate cancer alone accounts for nearly a third (29 percent) of cases in men.
The three most commonly diagnosed types of cancer among women in 2007 will be cancers of the breast, lung and bronchus, and colon and rectum, accounting for more than half (52 percent) of estimated cancer cases in women. Breast cancer alone is expected to account for one in four (26 percent) new cancer cases among women.
Lung cancer surpassed breast cancer as the leading cause of cancer death in women in 1987. Lung cancer is expected to account for 26 percent of all female cancer deaths in 2007.
Colorectal cancer incidence rates decreased from 1998 through 2003 in both males and in females.
Female breast cancer incidence rates leveled off from 2001 to 2003 after increasing since 1980, which may reflect the saturation of mammography utilization and dramatic reduction in hormone replacement therapy use that followed publication of the Women’s Health Initiative in 2002.
Among males under age 40 years, leukemia is the most common fatal cancer, while cancer of the lung and bronchus predominates in men aged 40 years and older.
African American men have a 15 percent higher incidence rate and 38 percent higher death rate than white men. African American women have a nine percent lower incidence rate, but an 18 percent higher death rate than white women for all cancer sites combined.
