(University of Southern California) A new study finds that precision medicine for oncology -- genetic testing to determine the best drug treatment for each cancer patient -- is not always so precise when applied to people of non-European descent. Researchers found that precision medicine using a tumor-only approach to guide therapeutic intervention is less precise for people whose ancestors are from Latin America, Africa and Asia.
