Abstract

The dosage of cisplatin is adjusted according to creatinine clearance (Ccr) estimated by the Cockcroft-Gault formula, which is commonly used as a marker for renal function. It is known that different serum creatinine (Scr) levels are reported depending on the analytical methods utilized such as the Scr level by the enzyme method being lower than that by the Jaffe method. Although the enzyme method is used in Japan, most drug dosages, including cisplatin, are adjusted according to the estimated Ccr using the Jaffe method-based Scr level. The purpose of this study was to investigate whether assessment of renal function with or without Scr adjustment affects cisplatin-based chemotherapy in cervical cancer patients. The patients were divided into two groups, normal (Ccr≥60 mL/min with adjusted Scr) and false normal (Ccr<60 mL/min with adjusted Scr, but Ccr≥60 mL/min with non-adjusted Scr). The false normal group had significantly higher rates of cisplatin dose reduction after the second course than the normal group ( p<0.05). Leukocytopenia and Grade 2 or higher neutropenia were significantly more common in the false normal group than in the normal group ( p<0.05). These results suggest that evaluation of renal function using the adjusted Scr is important for the accurate dosage of cisplatin and that it helps to improve the patient's quality of life. Further investigations may provide useful information for accurate and safe cisplatin-based chemotherapy for cancer patients.
