Brief Summary:

Pediatric cancer patients are being asked to take part in this study who have a cancer that is treated with high doses of the drug methotrexate (MTX). In addition, these patients have either had significant side effects to methotrexate in the past or their doctor thinks that they are at high risk for side effects from receiving methotrexate. Methotrexate is a cancer-fighting drug that is very important in the treatment of leukemia.

In this study, investigators are testing a new method of giving high dose methotrexate to cancer patients which may reduce the chances that the level of methotrexate in the blood is too high. When the levels are too high this is thought to lead to an increase in side effects. Side effects are unintended and unwanted results of treatment.

The initial ordered amount of methotrexate and the period over which methotrexate is given will not change from the current standard of care (meaning what is usually done by doctors, and would likely be done if the patient was not on this study). This study is testing a new method of monitoring and potentially adjusting the final amount of methotrexate that the patient will end up receiving based on levels of methotrexate in the blood in the first 24 hours in order to try to prevent side effects in patients with a previous history of side effects from methotrexate or who are at high risk for having side effects.

On this study the investigators will check methotrexate levels in the blood 2 hours after the patient starts receiving the drug and the investigators will lower the dose of methotrexate if needed. Investigators will do the same thing again 6-8 hours later.

Investigators will also collect an optional blood sample from the patient because the investigators want to study how genetic (DNA) differences are involved in how the body processes methotrexate.

Arm Intervention/treatment
Experimental: Individualized High Dose Methotrexate
Individualized high dose methotrexate given as a 24-hour infusion.
Drug: Methotrexate

Patients will receive 5g/m^2 high dose methotrexate as a 24 hour infusion.

The methotrexate level in the blood will be checked at two times during the 24-infusion. The dose will be reduced based on the level in the blood.

Primary Outcome Measures :
  1. Incidence of Success (Achieving an End Infusion Peripheral Blood Methotrexate Concentration Between 50-80 μM) [ Time Frame: 1 month ]
    1a) Calculate the incidence of success with the new protocol (achieving an end infusion peripheral blood methotrexate concentration between 50-80 μM)

Secondary Outcome Measures :
  1. Incidence of >Grade 3 Nephrotoxicity [ Time Frame: 2.5 months ]
    Calculate the incidence of >grade 3 nephrotoxicity

  2. Incidence of Neurotoxicity [ Time Frame: 2.5 months ]
    Calculate the incidence of neurotoxicity

  3. Incidence of Mucositis [ Time Frame: 2.5 months ]
    Calculate the incidence of mucositis

  4. Incidence of Hepatoxicity [ Time Frame: 2.5 months ]
    Calculate the incidence of hepatotoxicity

  5. Incidence of Myelosuppression [ Time Frame: 2.5 months ]
    grade >/= 3 hematological toxicity

Other Outcome Measures:
  1. Description of the Genotype of Various Methotrexate Metabolizing SNPs [ Time Frame: 4 weeks ]
    We described the genotype of various identified methotrexate metabolizing SNPs

  2. Examination of Predictors of Success in Achieving Goal Concentration of Methotrexate [ Time Frame: 4 weeks ]
    We examined the predictors of success in achieving goal concentration of methotrexate

Inclusion Criteria:

  1. Age: Patients must be greater than or equal to 365 days and less than 23 years of age at the time of enrollment.
  2. Diagnosis: Patients with any malignancy who will receive high dose methotrexate (HDMTX) given as a 5 g/m2 infusion over 24 hours and a history of ≥ 1 of the following:

    • Documented decreased renal function, defined as Creatinine greater than 1.5 x baseline or glomerular filtration rate (GFR) <65ml/min/1.73m2.
