Study summary

The purpose of this study is to compare different estimates of calculating creatinine clearance by mathematical formula and compare them to creatinine clearance based on a timed urine collection in patients who received high-dose methotrexate for the treatment of primary CNS lymphoma or CNS involvement of systemic lymphoma.

Read the detailed description

We intend to perform a retrospective chart review to identify a serum creatinine-based equation that gives the best estimate of CrCl as compared with an equation derived from a 24-hour urine collection.

Study subjects will be identified using the Brigham and Women's Hospital and Dana-Farber Cancer Institute's Adult Pharmacy systems to identify patients who received high-dose methotrexate. Data will be collected starting with December 31, 2010 and proceeding chronologically backwards until the target enrollment of 40 patients is reached.

What researchers measure

Primary outcomes

  1. To identify a serum creatinine-based equation that gives the best estimate of CrCl as compared to a measured creatinine clearance formula.

    Serum creatinine-based equations to be included in that analysis are: Cockcroft-Gault with the following weight descriptors; ideal body weight, actual body weight, and adjusted body weight; Modified MDRD; CKD-EPI.

    Time frame: 1 year

Secondary outcomes

  1. To further compare each formula in a different subset of patients.

    To further compare each formula in a different subset of patients: Age \< 65 years and \>/= 65 years; body mass index \< 25, 25-30, 30-35, and \> 35; serum creatinine \<1.5 mg/dL and \>/= 1.5 mg/dL.

    Time frame: 1 year
