NUDT15 genetic variants and 6-mercaptopurine intolerance in pediatric acute lymphoblastic leukemia: an updated review
Acute lymphoblastic leukemia (ALL) accounts for nearly 30% of pediatric cancers. The maintenance treatment for ALL comprises daily oral 6-mercaptopurine (6-MP) and weekly methotrexate (MTX). 6-MP is a purine analog that can significantly improve the long-term survival of ALL patients. Despite more than 90% of 5-year survival of childhood ALL in developed countries, treatment interruption due to...
متن کاملTPMT and ITPA Gene Polymorphism and Their Adverse Events during Chemotherapy of Acute Lymphoblastic Leukemia among Bangladeshi Children
Background: The pharmacogenetic-oriented approach reduces the toxicity and increases the safety of chemotherapeutic agents. 6-mercaptopurin (6-MP) metabolizing enzymes such as thiopurine S-methyltransferase (TPMT) and inosine triphosphate pyrophosphatase (ITPA) contribute to variable responses and adverse effects among leukemia patients treated with 6-MP. The aim of our study was to identify th...
متن کاملAdherence to 6-Mercaptopurine in children and adolescents with Acute Lymphoblastic Leukemia
OBJECTIVE Studies on children with Acute Lymphoblastic Leukemia (ALL) reported non-adherence in 2-54% of cases. The primary objective of this study was to assess rates of adherence to 6-MP using two different methods in children and adolescents with ALL. Secondary aim was to identify factors that influence adherence to 6-MP in children with ALL. METHODS All eligible children with ALL who are ...
متن کاملBrain MRI Findings in Children with Acute Lymphoblastic Leukemia
Background: Patients with leukemia are facing more complications in order to achieve longer survival. We aimed to evaluate the frequency of central nervous system abnormalities (CNS) on MRI of children with acute lymphoblastic leukemia (ALL). Methods: Sixty-six children with diagnosis of ALL aged 2-18 years were recruited. Non-contrast sequences of brain MRI in addition to diffusion weighted i...
متن کاملComparison of Direct Sequencing, Real-Time PCR-High Resolution Melt (PCR-HRM) and PCR-Restriction Fragment Length Polymorphism (PCR-RFLP) Analysis for Genotyping of Common Thiopurine Intolerant Variant Alleles NUDT15 c.415C>T and TPMT c.719A>G (TPMT*3C)
Thiopurine intolerance and treatment-related toxicity, such as fatal myelosuppression, is related to non-function genetic variants encoding thiopurine S-methyltransferase (TPMT) and Nudix hydrolase 15 (NUDT15). Genetic testing of the common variants NUDT15:NM_018283.2:c.415C>T (Arg139Cys, dbSNP rs116855232 T allele) and TPMT: NM_000367.4:c.719A>G (TPMT*3C, dbSNP rs1142345 G allele) in East Asia...
