Targeting Cancer’s Own Stem Cells to Fight Recurrence

New research demonstrates that cancer stem cells or “tumor-initiating cells,”  when targeted with a reprogrammed herpes virus, can be prevented from turning malignant and re-initiating disease.  The finding bolsters the theory that cancer harbors its own secret cache of stem cells that are resistant to conventional therapies and responsible for tumor re-emergence.  This type of virus-against-cancer therapy may be the next generation of anti-cancer treatments.  The study was published online Jan. 21 in the journal PLoS (Public Library of Science) One.
