UAMS Study Finds Genetic Subtypes of Myeloma, Hope for Targeted Treatments
UAMS Study Finds Genetic Subtypes of Myeloma, Hope for Targeted Treatments
Little Rock, AR (PRWEB) September 19, 2006
A genetic analysis of more than 400 patients with multiple myeloma (http://myeloma.uams.edu/), a cancer of the bone marrow, identified seven subtypes of the disease that had a bearing on a patient’s prognosis and offered the potential for targeted treatments, reported a team of researchers from the Myeloma Institute for Research and Therapy (MIRT – http://myeloma.uams.edu/) in the September issue of the journal Blood.
The researchers from the Myeloma Institute, located on the campus of the University of Arkansas for Medical Sciences (UAMS – http://www.uams.edu), used gene expression profiling to analyze bone marrow plasma cells from 414 newly diagnosed myeloma patients. Of the seven genetic disease subtypes identified, four were associated with better patient outcomes following high-dose chemotherapy and a stem cell transplantation.
An article on the study, “The molecular classification of multiple myeloma,” is published in the Sept. 15, 2006, issue of Blood, the journal of the American Society of Hematology. The article is available online at http://www.bloodjournal.org/.
“These results are likely to have a profound influence on the diagnosis, prognosis and treatment of multiple myeloma,” said John D. Shaughnessy Jr., Ph.D., director of the Lambert Laboratory (http://lambertlab.uams.edu/)in the MIRT. “While on the surface most myelomas look alike, the power of modern molecular techniques has allowed us to identify the specific genetic switches that are altered in each disease subtype and these insights may offer entry points for new tailored therapeutic options.”
The study noted that although high-dose therapy improved the prognosis for patients with multiple myeloma, individual patients’ survival remains variable and unable to be accurately predicted. The researchers said the relationship between the disease subtypes and survival rates should lead to better risk stratification.
