A new study on the incidence of liver cancer after transplant found that high levels of the immunosuppressant cyclosporine favored tumor recurrence and identified blood levels of the drug that should not be exceeded. Lower levels of cyclosporine levels did not affect rejection rates. The results of this study appear in the May 2005 issue of Liver Transplantation, the official journal of the American Association for the Study of Liver Diseases (AASLD) and the International Liver Transplantation Society (ILTS). The journal is published on behalf of the societies by John Wiley & Sons, Inc. and is available online via Wiley InterScience at http://www.interscience.wiley.com/journal/livertransplantation.
