| 1 | The Promise of Pharmacogenomics in ReducingToxicity During Acute Lymphoblastic LeukemiaMaintenance Treatment显示文摘Pediatric acute lymphoblastic leukemia(ALL) affects a substantial number of children every year and requires a long and rigorous course of chemotherapy treatments in three stages, with the longest phase, the maintenance phase, lasting 2–3 years. While the primary drugs used in the maintenance phase, 6-mercaptopurine(6-MP) and methotrexate(MTX), are necessary for decreasing risk of relapse, they also have potentially serious toxicities, including myelosuppression, which may be life-threatening, and gastrointestinal toxicity. For both drugs, pharmacogenomic factors have been identified that could explain a large amount of the variance in toxicity between patients, and may serve as effective predictors of toxicity during the maintenance phase of ALL treatment.6-MP toxicity is associated with polymorphisms in the genes encoding thiopurine methyltransferase(TPMT), nudix hydrolase 15(NUDT15), and potentially inosine triphosphatase(ITPA), which vary between ethnic groups. Moreover, MTX toxicity is associated with polymorphisms in genes encoding solute carrier organic anion transporter family member 1B1(SLCO1B1) and dihydrofolate reductase(DHFR). Additional polymorphisms potentially associated with toxicities for MTX have also been identified, including those in the genes encoding solute carrier family 19 member 1(SLC19A1)and thymidylate synthetase(TYMS), but their contributions have not yet been well quantified. It is clear that pharmacogenomics should be incorporated as a dosage-calibrating tool in pediatric ALL treatment in order to predict and minimize the occurrence of serious toxicities for these patients. | Shoshana Rudin Marcus Marable R.
