Clinical Trial Results - Progress in Cancer Care
These summaries highlight recently released results from cancer clinical trials. The findings are significant enough that they are likely to influence your medical care.
The summaries are listed in reverse chronological order. You may also use the navigation tools on the left to search the summaries by keyword or type of cancer.
1. Review of Prostate Cancer Prevention Study Shows No Benefit for Use of Selenium and Vitamin E Supplements
(Posted: 10/27/2008, Updated: 12/09/2008) - Initial, independent review of study data from the Selenium and Vitamin E Cancer Prevention Trial (SELECT), funded by the National Cancer Institute (NCI) and other institutes that comprise the National Institutes of Health shows that selenium and vitamin E supplements, taken either alone or together, did not prevent prostate cancer. The data also showed two concerning trends: a small but not statistically significant increase in the number of prostate cancer cases among the over 35,000 men age 50 and older in the trial taking only vitamin E and a small, but not statistically significant increase in the number of cases of adult onset diabetes in men taking only selenium.
2. New Targeted Fluorescent-Imaging Compound Allows Researchers to Detect Viable Cancer Cells in Mice
(Posted: 12/08/2008) - Researchers have developed a new type of imaging compound that allows them to visualize viable breast cancer cells that have spread to the lungs in mice. The compound binds to a protein called HER2, which is found on the surface of some breast cancer cells, and it glows, or fluoresces, only when taken inside living cells. This method of targeting and activation allowed researchers to detect specific types of live cancer cells in a mouse model of breast cancer.
3. Depression Management Effective in Low-Income Hispanic Cancer Patients
(Posted: 11/20/2008) - A collaborative-care intervention to treat depression in cancer patients was more effective than usual care in relieving symptoms of depression among low-income Hispanics, according to the Sept. 20, 2008, Journal of Clinical Oncology.
4. High Dose Chemotherapy Significantly Prolongs Survival for Patients with Acute Myeloid Leukemia
(Posted: 11/17/2008) - Preliminary results from a large, randomized clinical trial for patients ages 16 to 60 with previously untreated acute myeloid leukemia, a cancer of the blood and bone marrow, show that patients who received a high dose of a commercially available chemotherapy drug, daunorubicin, during initial therapy lived longer than patients who received a standard dose of the same drug.
5. Colorectal Cancer Trials Support Gene Testing for Two Drugs
(Posted: 11/12/2008) - A trio of 2008 studies adds to the growing evidence that patients with colorectal cancer should have their tumors tested for genetic mutations prior to starting therapy with cetuximab (Erbitux) or panitumumab (Vectibix).
