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.

- To identify a serum creatinine-based equation that gives the best estimate of CrCl as compared to a measured creatinine clearance formula. [ Time Frame: 1 year ]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.
- To further compare each formula in a different subset of patients. [ Time Frame: 1 year ]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.
