The clinical significance of calculated versus measured creatinine clearance in patients with gynecologic malignancy.
Measurement of creatinine clearance remains in convenient because of the need for 24-hour urine collection. Our study compared creatinine clearance calculated from serum creatinine (CC alpha) to measured creatinine clearance (MC alpha) using an unsupervised 8-hour urine collection at home. Forty-two women admitted to our gynecologic oncology service participated in this study. Twenty-six of these patients had cancer originating from the ovaries, 8 from the uterus, 7 from the cervix, and 1 from the fallopian tube. There were adequate data for 61 collections. MC alpha using unsupervised 8-hour urine collection at home correlated well with CC alpha. This calculated value may be sufficient to be used as a guide in evaluating renal function in patients with gynecologic malignancy. However, if it becomes necessary to measure creatinine clearance, our data suggest that an 8-hour collection may be used.
