Evaluation of the Modified Diet in Renal Disease Equation for calculation of carboplatin dose. The glomerular filtration rate (GFR), the fluid volume filtered from the capillaries of the renal glomeruli into the Bowman's capsule per unit time, is used for calculations of carboplatin chemotherapy doses. In stage II, the authors used this formula to dose 31 patients for target AUCs of 3-8 mg/mL per minute. Carboplatin is a second-generation platinum compound with a broad spectrum of antineoplastic properties. Carboplatin dosage is calculated from sex, age, weight, serum creatinine and AUC (Area Under the Curve) of carboplatin. The FDA has recommended that physicians consider capping the dose of carboplatin for desired exposure (AUC) to avoid potential toxicity due to overdosing. In routine oncologic practice, the carboplatin dosage is usually estimated based on AUC-based dosing since carboplatin clearance closely matches creatinine clearance. Additional factors that should be assessed include: previous exposure to chemotherapy or radiotherapy, and overall health status. Regardless of the number of cycles, the optimal dosing of carboplatin is calculated by the formula ( Calvert and Egorin, 2002 ). AUC 4 = 600 mg . AUC = target area under the concentration versus time curve in mg/mLmin. May alternatively be given at AUC 1.5 on Days 1, 8, and 15; Paclitaxel 80 mg/m 2 I.V. Carboplasm will be administered 1 hour prior to the gemcitabine infusion, bevacizumab will be administered 1 hour following chemotherapy infusion.

Maximum Infusion reactions to systemic chemotherapy reactions (of all types) with carboplatin is approximately 12 percent . After a bit more number crunching, they came up with what is now known as the Calvert formula - a calculation that's still used to this day to calculate the correct dose of carboplatin. This formula can be used to calculate the carboplatin dose accurately in order to obtain a target AUC by using only the GFR. How is the carboplatin AUC and dosage calculated?

Our carboplatin calculator computes the carboplatin dose in two steps: Calculating GFR using the Cockcroft-Gault equation: MEN: GFR = ( (140 - A) W / (72 Cr) WOMEN: GFR = 0.85 GFR formula for men where: `GRF`- Glomerular Filtration Rate `A` - age (years) `W` - weight (kg) `Cr` - serum creatinine (mg/dL) FAQ. 5 Which is more accurate, carboplatin GFR or AUC? AUC 5 = 750 mg . GFR for female (mL/min) describes the flow rate of filtered fluid through the kidney. Glomerular Filtration Rated was estimated mainly by Cockroft-Gault formula (55% of pts), Jeliffe formula (27%), 24-hour urine collection (17%), MDRM (1%): median value was 106 ml/min (range 75 to 209). Utilize the carboplatin dose calculator by the following method: Input: Select the gender Enter the age and weight of the patient Enter the serum creatinine level Enter the targeted AUC Hit the calculate button to find the dosage Output: The Calvert formula calculator displays the following result: Glomerular Filtration Rate (GFR) displayed AUC = target area under the concentration versus time curve in mg/mLmin. The maximum dose is based on a GFR estimate that is capped at 125 mL/min for patients with normal renal function. CARBOplatin is administered once every 7 days concomitantly with radiotherapy for 6 cycles.
