An anti-allergy drug in use for more than 40 years significantly reduced tumor growth in animal models of human pancreatic cancer and also increased the effectiveness of standard chemotherapy, say researchers at M. D. Anderson. In the Dec. 20 issue of the Journal of the National Cancer Institute, the investigators report that combining the drug, cromolyn, with chemotherapy was nearly three times better at retarding growth of pancreatic tumors in mice compared to the chemotherapy agent gemcitabine alone.
