ABSTRACT
Mercaptopurine (6-MP), a critical component of acute lymphoblastic leukemia (ALL) therapy, is metabolized to 6-thioguanine (6-TGN) which is responsible for its anti-leukemic effect, and to 6-methylmercaptopurine nucleotides (6-MMPN/6-MMP) which can be hepatotoxic. Some patients preferentially metabolize 6-MP to 6-MMPN which may increase the risk of liver injury, reduce serum levels of 6-TGN and potentially increase the risk of relapse. The addition of allopurinol to oral 6-MP has been shown to optimize metabolism towards 6-TGN in patients with inflammatory bowel disease (IBD); however, this use has not been reported in patients undergoing treatment for ALL.
