People with genetic disorder linked to long life have increased death rate from a common cancer drug

CANCER DIGEST – Nov. 13, 2016 – Cancer patients with a genetic disorder that has been linked to long life, ironically may be twice as likely to die when treated with a common chemotherapy drug, a new analysis shows.

Led by George McDonald, MD a gastroenterology researcher at Fred Hutchinson Cancer Research Center in Seattle, researchers analyzed the records of 3500 marrow transplant patients over a ten-year period between 1991 and 2011. The records analyzed included people who had been treated with busulfan as part of a chemotherapy regimen prior to bone marrow transplantation for blood cancers like leukemia or lymphoma.
