Methotrexate Therapy for Pediatric Leukemia

Cited 16 times

Patients who consented to the optional therapeutic window were randomized to receive upfront methotrexate over 4 or 24 hours. Four days after methotrexate treatment, remission induction therapy began with prednisone, vincristine, daunorubicin, and asparaginase (Table 1). Patients with ≥ 1% MRD on day 19 received three additional doses of asparaginase. Subsequent induction therapy consisted of cyclophosphamide, mercaptopurine and cytarabine. Upon hematopoietic recovery (between days 43 and 46), MRD was assessed, and consolidation therapy began (Table 1).

During initial continuation therapy (Table 1), low-risk cases received daily mercaptopurine and weekly methotrexate with pulses of mercaptopurine, dexamethasone and vincristine. Two reinduction treatments were given between weeks 7–9 and weeks 17–19. Standard-risk cases received weekly asparaginase and daily mercaptopurine with pulses of doxorubicin plus vincristine plus dexamethasone. They also received two reinduction treatments between weeks 7–9 and weeks 17–20.
For the remaining continuation therapy (Supplementary Table 1), low-risk patients received mercaptopurine and methotrexate, with pulses of dexamethasone, vincristine and mercaptopurine, and standard-risk patients received three rotating drug pairs (mercaptopurine plus methotrexate, cyclophosphamide plus cytarabine, and dexamethasone plus vincristine). Dosages of mercaptopurine and methotrexate were adjusted according to the tolerance, and thiopurine methyltransferase phenotype and genotypes.17 (link) Total scheduled dosages of anthracyclines and cyclophosphamide were limited to 110 mg/m² and 230 mg/m², and 1 g/m² and 4.6 g/m², for low-risk and standard-risk patients, respectively. Continuation treatment lasted 120 weeks in girls and 146 weeks in boys.

What are some specific applications of Asparaginase?

More about "Asparaginase"

Asparaginase is an essential enzyme that plays a crucial role in the treatment of certain types of cancer, particularly acute lymphoblastic leukemia (ALL).
This enzyme catalyzes the hydrolysis of the amino acid L-asparagine, converting it into aspartic acid and ammonia.
This process is particularly beneficial for cancer cells, as they are often dependent on external sources of L-asparagine for their growth and survival.
By depriving these cells of this essential nutrient, asparaginase effectively starves the cancer cells, leading to their demise.
In addition to its use in cancer treatment, asparaginase is also employed in the food processing industry to reduce the formation of acrylamide, a potentially carcinogenic compound.
Acrylamide can be formed during high-temperature cooking processes, and asparaginase helps to mitigate this risk by breaking down the precursor, L-asparagine.
Researchers can leverage the power of PubCompare.ai to optimize their asparaginase-related research.
This AI-driven platform allows users to effortlessly locate the best protocols and products from literature, preprints, and patents, enhancing the reproducibility and accuracy of their work.
By taking the guesswork out of the research process, PubCompare.ai empowers researchers to focus on their core objectives, ultimately accelerating scientific progress.
To further enrich the understanding of asparaginase, it is worth exploring related terms and concepts.
L-asparaginase is a specific form of the enzyme, while L-asparagine is the amino acid that asparaginase acts upon.
Fetal bovine serum (FBS), dexamethasone, L-glutamine, and rapamycin are all commonly used in cell culture experiments involving asparaginase.
Additionally, DMSO (dimethyl sulfoxide) is often used as a solvent for asparaginase, and a FACSCalibur flow cytometer may be employed to analyze the effects of asparaginase on cell populations.
Chloroquine, an antimalarial drug, has also been studied in combination with asparaginase for its potential synergistic effects in cancer treatment.
By incorporating these related terms and concepts, researchers can gain a more comprehensive understanding of the broader context surrounding asparaginase and its applications.
This knowledge can lead to more informed experimental design, improved research outcomes, and ultimately, advancements in the field of asparaginase-based therapies and applications.
