Carboplatin dosing in obese patients during pregnancy: CARBOplatin

A dose decrease might be suitable for cyclophosphamide. Both formulas were developed and validated using non-IDMS creatinine values.

Data from another randomized phase 3 study support the use carboplatin dosing in obese patients during pregnancy carboplatin in combination with atezolizumab, bevacizumab, and paclitaxel as first-line treatment of metastatic NSCLC or recurrent metastatic non-squamous NSCLC carboplatin dosing in obese patients during pregnancy untreated with chemotherapy in patients without eGFR or ALK genomic tumor alterations or with eGFR or ALK alterations and disease progression on or intolerance to a tyrosine kinase inhibitor [Socinski ]. Rounding of low serum creatinine levels and consequent impact on accuracy of bedside estimates of renal function in cancer. Secondary Objective s The secondary objective is to evaluate progression-free survival in this patient population. Scand J Clin Lab Invest. Gynecologic Malignancies. The Cockcroft-Gault CG equation has been in use in clinical practise for many years Cockcroft and Gault, ; Rostoker et aland is often used when prescribing anticancer drugs, although in our cancer centre at St George's it is more commonly used between chemotherapy cycles for monitoring renal function.

  • Data from a smaller phase 2 study also support the use of carboplatin in combination with docetaxel in the management of unknown primary adenocarcinoma [Greco ].

Patients and methods

Data suggest an increased dose of carboplatin, cisplatin, ifosfamide, paclitaxel, and carboplatin dosing may be needed obese patients obese patients. In patients with during pregnancy low serum creatinine they recommended using carboplarin minimum serum creatinine value of 0. However, a flat dose based on the population carboplatin clearance performed better in all weight categories than the use of the Cockcroft-Gault equation with diverse weight descriptors. Purpose: The purpose of this study was to determine the potential utility of alternative weight descriptors in the Cockcroft-Gault equation to more accurately predict carboplatin clearance in underweight, normal weight, overweight and obese patients.

Therefore, in parients with relatively low serum creatinine the IDMS method generated abnormally low values, leading to an overestimation of creatinine clearance and consequently higher calculated carboplatin doses. Sabbatini, MD Saturday, September 1, Carboplatin-based chemotherapy remains the mainstay of treatment for many patients with gynecologic malignancies. If the creatinine at the time of dose modification is higher than the baseline creatinine value, they recommended using the current higher value. They recommended capping the maximum carboplatin dose based on target area under the curve AUC. Abstract Purpose: The purpose of this study was to determine the potential utility of alternative weight descriptors in the Cockcroft-Gault equation to more accurately predict carboplatin clearance in underweight, normal weight, overweight and obese patients. Substances Antineoplastic Agents Creatinine Carboplatin. The literature also suggests that no dosing alteration may be necessary for obese patients receiving topoisomerase I and II inhibitors, 5-fluorouracil, methotrexate, and docetaxel.

In some patients with normal renal function, the new standardized IDMS method produced creatinine values that were on carboplatin dosing in obese patients during pregnancy 10 to 20 percent lower than older, non-IDMS values. Conclusion: Some cytotoxic agents used in practice have altered pharmacokinetics in obese patients. Dose capping has been used to limit excess toxicity in obese patients at the risk of providing a less-effective regimen. Although the creatinine clearance is always slightly higher than the GFR, the two estimates of renal function are used interchangeably in the Calvert formula. Historically, the Gynecologic Oncology Group GOG used a different formula, the Jelliffe equation, to estimate creatinine clearance for carboplatin dosing.
