MRI scans of children who have had chemotherapy can detect early changes in their hearts finds research in biomed Central's open access journal Journal of Cardiovascular Magnetic Resonance. Chemotherapy with anthracyclines, such as Doxorubicin, is one of the most effective treatments against many types of cancer, including leukaemia and Hodgkin's lymphoma, breast, lung, and ovarian cancer.
A new study has found that women can be screened for colorectal cancer at least five to 10 years later than men when undergoing an initial "virtual colonoscopy." Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings may help establish guidelines for the use of this screening technique, which is less invasive than a traditional colonoscopy.
Three out of 20 flexible gastrointestinal (GI) endoscopes used for screening were found to harbor unacceptable levels of "bio dirt" – cells and matter from a patient's body that could pose potential infection risk -- according to a study of endoscopes used at five hospitals across the U.S.
The average 5-year survival for colorectal cancer is less than 10% if metastasis occurs, but can reach 90% if detected early. A new non-invasive test has been developed that measures methylation of the SDC2 gene in tissues and blood sera. This test detected 87% of all stages of colorectal cancer cases (sensitivity) without significant difference between early and advanced stages.
New research has found that routine screening using a non-invasive test that analyzes fetal DNA in a pregnant woman's blood can accurately detect Down's syndrome and other genetic fetal abnormalities in the first trimester. Published early online in Ultrasound in Obstetrics & Gynecology, the results suggest that the test is superior to currently available screening strategies and could reshape standards in prenatal testing.
Today, two scientists from Cold Spring Harbor Laboratory (CSHL) publish a mathematical method of simplifying and interpreting genome data bearing evidence of mutations, such as those that characterize specific cancers. Not only is the technique highly accurate; it has immediate utility in efforts to parse tumor cells, in order to determine a patient's prognosis and the best approach to treatment.
MRI may be an effective way to diagnose mental illnesses such as bipolar disorder, according to experts from the Icahn School of Medicine at Mount Sinai.
