Janowitz T, Williams EH, et al. Because carboplatin clearance depends largely on GFR, the carboplatin dose needed to achieve a target AUC has historically been calculated starting with an assessment of All material on this website is protected by copyright, Copyright 1994-2022 by WebMD LLC. All hospitals used the Calvert formula to calculate carboplatin dose with glomerular filtration rate estimated by a formula, most commonly the Cockcroft-Gault equation (80.7%). This tool estimates the total Carboplatin dose (in mg) based on the Cockcroft Gault equation which provides the estimated creatinine clearance level which is then adjusted by the target AUC. DICP. The dose of carboplatin was administered to the patient and pharmacokinetic levels were obtained. Modification of Diet in Renal Disease Study 1976;16(1):31-41; FDA Center for Drug Evaluation and Research. Use the Cockcroft and Gault method to calculate estimated creatinine clearance: CrCl = (140 - age) x wt. Start. carboplatin dose reduction of as little as 10% was sug-gested to result in a doubling of 5-year relapse rate.5 Both studies highlight the importance of accurate dosing. Results Calculate Multiply extremes, then means (outer . Nephron. Knowing the GFR of a patient and using the target AUC value of 6 mg/ml/min, we can calculate carboplatin dose for the patient. Remember that the results from the calculator are for informational purposes only and you should ask for professional advice and explanation result. (Age, Weight, Gender, Serum creatinine) Creatinine Clearance Value = (140-age) (weight kg) / (72 X S cr) in mL/min. This method also provides useful information about the kidney function because it computes the creatinine clearance rate. He is co-chair of Airways Research Group and the chair of the Quality Assurance Committee. The CrCl Cockroft-Gault calculator is created by QxMD. A measured creatinine of less than 0.8 mg/dl may not be reflective of fantastic renal function. the auc determines toxicity of carboplatin. CrCl for serum creatinine in mg/dL = [(140 - age) x Weight in kilograms (x 0.85 if female)] / (Serum Creatinine in mg/dL x 72), CrCl for serum creatinine in mol/L = [(140 - age) x Weight in kilograms x (1.23 if male or 1.04 if female)] / (Serum Creatinine in mol/L). Now we know the GFR value of the patients using the target AUC which is around 7 mg/ml/min, we can find the dosage of the Carboplatin of the patient. Ann Intern Med Creatinine clearance (Ccr), calculated using the Cockroft-Gault, Jelliffe, Modified-Jelliffe or Wright formulae, has been used as a substitute for the GFR. If your patient is overweight or obese (calculated BMI 25 kg/m), consider using adjusting body weight for your carboplatin dose calculator. (1989) Carboplatin dosage: prospective evaluation of a simple formula based on renal function. The dose of carboplatin in the MRC TE19/EORTC 30982 trial was calculated by the Calvert formula [ 4 ]: [GFR + 25] AUC, with a target AUC (area under the plasma concentration curve) of 7. In addition to these four formulae, the Chatelut formula has been proposed as a way to calculate carboplatin clearance. Target AUC values differ depending on the status of the patient: For patients already treated, target AUC should be around 4 7 mg/mL/min; For patients without previous treatment target AUC should be around 6 8 mg/mL/min. Calvert AH, Newell DR, Gumbrell LA, et al. All Rights Reserved. Target AUC usually has values around 4-7 mg/ml/min in clinical practice for already treated patients but for those without previous chemotherapy sessions the target should revolve around 6-8 mg/ml/min. J Clin Oncol. With our water intake calculator, you don't need to rack your brain any longer! If the Cockcroft and Gault (C-G) creatinine clearance (CrCl) equation is utilized and substituted for glomerular filtration rate in the Calvert formula, the chance for inaccurate dosing occurs especially in these populations.

This carboplatin dosing calculator uses the Calvert method to calculate the total carboplatin dose needed to achieve a given AUC (area under the free carboplatin plasma concentration versus time curve) while taking into account renal function. The calculation of the ideal body weight by Devines formula: Male = 50 kg + (2.3 * (Height in inches - 60)), Female = 45.5 kg + (2.3 * (Height in inches - 60)). Am J Nephron; 16(1):31-41. This information is not intended to replace clinical judgment or guide individual patient care in any manner. If Cockcroft & Gault or Wright formula are used, the dose should be adjusted per cycle based on a serum creatinine obtained within 48 hrs of drug administration If isotope GFR is used, the dose should remain the same provided the serum creatinine is 110% irAEs Tool. Am J Hosp Pharm This calculator calculates carboplatin doses via the Calvert formula with a target Area Under the Curve (AUC), using three options for kidney function: Directly Measured GFR (mGFR)* Body Surface Area (BSA) Adjusted eGFR CKD-EPI ** Creatinine Clearance (CrCl) calculated via the Cockcroft-Gault equation J Clin Oncol. 2002 National Kidney Cockcroft DW, Gault MH. Check out 56 similar general health calculators . Pharmacotherapy 2011 31:7 , The Calvert formula was developed using the clearance of 51 Cr-ethylenediamine tetraacetic acid ( 51 Cr-EDTA) as measure of GFR (glomerular filtration rate). Conclusion These results suggest that in overweight and obese patients, with a normal renal function, a at carboplatin dose should be administered, based on the population carboplatin clearance (8.38 l/h = 140 mL/min). Hypothetically, even if the administered carboplatin dose was exactly as calculated from Cockcroft-Gault equation and manufacturer's recommendation, majority (83.1% and 81.8%, respectively) would have still received a lower dose compared to the reference and those receiving 20% overdose would have been only two (2.6%) and three (3.9% . If Cockcroft & Gault or Wright formula are used, the dose should be adjusted per cycle based on a serum creatinine Estimating If the serum creatinine is expressed in mol/L then: CrCl for male = [(140 - age) * Weight in kilograms * 1.23] / (Serum Creatinine in mol/L), CrCl for female = [(140 - age) * Weight in kilograms * 1.04] / (Serum Creatinine in mol/L). This information should not be used for the diagnosis or treatment of any health problem or disease.
