概要 |
[Objective]Nephrotoxicity is diagnosed in 28-42% of patients applied cisplatin. Mg2+ is involved in active transport of cisplatin in proximal tubule cells, therefore, we retrospectively examined wheth...er Mg2+ supplementation prevent nephrotoxicity during cisplatin-containing chemotherapy. All patients provided written informed consent before treatment. [Methods]Forty four patients of gynecologic cancer treated in our hospital from Oct 2014 to Sep 2015(study group)were analyzed. They were supplied magnesium sulfate containing 8mEq of Mg2+ just before cisplatin administration. Serum creatinine level(Cr:mg/dL)and glomerular filtration rate(GFR:mL/min)were examined before and after treatment. These laboratory data were compared with those of 74 patients treated previously without Mg2+ supplementation(control group). [Results]Statistically significant Cr elevation(+0.11±0.17 vs -0.03±0.10)and GFR decrease(-13.0±22.2 vs+2.2±17.6)were found in control group compared with study group(p<0.001). Discontinuation of chemotherapy occurred in 8 cases in control group due to renal dysfunction. However, all patients in study group could receive scheduled treatment. [Conclusion]Magnesium sulfate supplementation might be effective for renal protection during cisplatin-containing chemotherapy.続きを見る
