Conditions

Acute Lymphoblastic Leukemia

Brief summary

The present study was conducted to assess the population pharmacokinetics of 6-mercaptopurine (6-MP) in Pediatric Acute Lymphoblastic Leukemia (ALL) and genetic polymorphisms

Detailed description

The investigators' purpose was to identify genetic factors and metabolite concentrations associated with both hematological toxicity in patients with ALL maintained on 6-MP in Chinese.

Interventions

DRUGMercaptopurine

Dose of mercaptopurine was adjusted to maintain a target white blood cells (WBC) between 2.0-3.0 × 109/L.

Inclusion criteria

* Patients have been diagnosed with Acute Lymphoblastic Leukemia * Childhood patients who were undergoing chemotherapy or continuous follow-up after completion of chemotherapy * Patients received the phase of maintenance therapy that included oral 6-MP (\>4 weeks) and completion of ≥ 6 months according to the CCLG (Chinese Children's Leukemia Group) protocol-ALL 2015

Exclusion criteria

* Patients with high-risk ALL (presence of higher-risk features: MRD ≥ 1% at 46 day, or age \< 6 month and white blood cell (WBC) count ≥ 300×109/L with translocations t(9;22) (q34;q11) \[BCR-ABL\], t(4;11) (q21;q23) \[AF4/MLL\], t(1;19) (q23;p13) \[E2A-PBX1\] or other MLL-rearrangements) were removed

Design outcomes

MeasureTime frameDescription
Red blood cells (RBC) concentration of 6-mercaptopurine (6-MP)at second day after oral administrationTo detect of RBC 6-MP metabolite concentrations and evaluate the association of metabolite concentrations and side effects
Genetic polymorphisms in Chinese patients with ALLat second day after oral administrationTo detect the frequencies of genetic polymorphisms of Chinese patients receiving 6-MP for treatment of ALL
