"The case raised the question in medical circles of whether a liver
transplant is a viable option for a leukemia patient because of the immune-
system-suppressing medication such patients must take to prevent organ
rejection. Such medication, while preserving the transplanted liver, could
make the cancer worse.
"Transplantation is not an option for leukemia patients because the
immunosuppressant drugs 'tend to increase the risk and growth of any
tumors,' said Dr. Stuart Knechtle, who heads the liver transplant program
at the University of Wisconsin at Madison and was not commenting
specifically on Nataline's case.
"The procedure 'would be futile,' he said."

company.
