  • Title: Carboplatin dosing: gender bias and inaccurate estimates of glomerular filtration rate.
    Author: Dooley MJ, Poole SG, Rischin D, Webster LK.
    Journal: Eur J Cancer; 2002 Jan; 38(1):44-51. PubMed ID: 11750838.
    Abstract:
    The aim was to compare doses of carboplatin calculated using the Calvert formula and Chatelut formula and also to compare doses calculated using Calvert formula, modified with non-isotopic estimation of GFR, using the Cockcroft and Gault formula or the Jelliffe formula. For formulae comparison, doses were calculated to target an AUC of 7 mg/ml x min. When compared with the dose derived from the Calvert formula, the doses calculated in 122 adult cancer patients using the Chatelut formula were significantly higher for males and significantly lower for females. There was a statistically significant difference between the dose per kg calculated for males and females (P<0.0001). The mean percentage difference in dose calculated with substituted measures of renal function with the Cockcroft and Gault formula and Jelliffe formula was -8% (standard deviation (S.D.) 17%) and -14% (S.D. 16%), respectively. Further prospective evaluation of the Chatelut formula is required before it can be recommended for routine clinical application.
